As used in this specification and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It should be further understood that the term "and/or" as used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.
In an embodiment of the present utility model, a vapor replenishment line 100 based on an evaporative heat exchange system is provided for timely replenishment of high temperature vapor upon start-up of the entire plant or insufficient vapor of the heat source.
As shown in fig. 1, the steam supplementing line 100 based on the evaporation heat exchange system includes a horizontal tube heat exchanger 10, a salt precipitation circulation line 20, a steam compressor 30, a condensed water tub 40, and a new high temperature and high pressure steam input line 50.
The transverse tube heat exchanger 10 comprises a feed liquid passage 11 and a steam passage 12 for heat exchange. The feed liquid passage 11 and the steam passage 12 are arranged in the same direction and in the opposite direction, so that efficient heat exchange can be performed. The feed liquid passage 11 is defined as a cold source to raise the temperature of the internal fluid, the steam passage 12 is defined as a heat source to flow high-temperature and high-pressure saturated steam (i.e. high-temperature steam) to provide heat to the fluid in the feed liquid passage 11, and after heat exchange, part of the high-temperature steam in a gaseous state (e.g. 160-170 ℃) is condensed into liquid high-temperature condensed water (e.g. 80-95 ℃).
Wherein, the two ends of the salt precipitation circulation pipeline 20 are respectively communicated with the two ends of the feed liquid passage 11. The salt precipitation circulation pipeline 20 comprises a salt precipitation tank 21, a circulation pump 22 and a circulation pipeline 23, and the circulation pipeline 23 is communicated with the inside and the outside of the salt precipitation tank 21. The salting-out tank 21 receives a connection between one end of the salting-out circulation line 20 and one end of the steam passage 12. After the feed liquid in the salt precipitation circulation pipeline 20 is heated by the transverse tube heat exchanger 10, secondary unsaturated steam is generated in the salt precipitation tank 21. The low-temperature evaporation raw water enters the feed liquid passage 11, so that the circulation in the salt precipitation circulation pipeline 20 is realized, and the evaporation crystallization process is participated. During the evaporation and crystallization process, the salt precipitation tank 21 precipitates salt crystals at the bottom, and secondary unsaturated vapors generated are accumulated at the top.
The vapor compressor 30 is communicated with the salt precipitation circulation line 20 (specifically, the top of the salt precipitation tank 21) through a first vapor line 301, the vapor compressor 30 is communicated with one end of the vapor passage 12 through a second vapor line 302, and the vapor compressor 30 is used for compressing the secondary unsaturated vapor generated from the salt precipitation tank 21 and input through the first vapor line 301 and then delivering the high-temperature and high-pressure saturated vapor to the second vapor line 302. Specifically, steam from the top of the salt precipitation tank 21 can enter the vapor compressor 30 through the first steam line 301. The vapor compressor 30 compresses the secondary unsaturated vapor, converts electric energy into heat energy to obtain high-quality high-temperature high-pressure saturated vapor, and then delivers the high-temperature high-pressure saturated vapor into the vapor passage 12 to provide a heat source.
The condensed water bucket 40 is communicated with one end of the steam passage 12 away from the second steam pipeline 302 to receive high-temperature condensed water formed after heat exchange between high-temperature high-pressure saturated steam in the steam passage 12 and the feed liquid passage 11. It can be understood that after the heat exchange of the high-temperature and high-pressure saturated steam, the temperature is reduced, and the saturated steam is condensed from a gaseous state to a liquid state and then flows into the condensed water bucket 40 to be collected. The high-temperature condensed water can preheat the low-temperature evaporation raw water and can be used for other purposes.
In the embodiment of the present utility model, one end of the new high temperature and high pressure steam input pipe 50 is connected to the steam generator 51, and the other end is connected to the second steam pipe 302. The steam generator 51 is used for generating new high-temperature high-pressure saturated steam and delivering the steam into the second steam pipeline 302. It can be understood that if the amount of steam in the steam passage 12 is insufficient or the temperature is insufficient, the circulating liquid in the circulating pipeline 23 cannot reach the predetermined temperature, and the secondary unsaturated steam generated during the evaporative crystallization is insufficient, so that the steam compressor 30 cannot generate enough high-quality high-temperature high-pressure saturated steam, and the thermal state balance of the whole heat exchange system is finally damaged, which makes the whole evaporative crystallization process difficult. Therefore, the high-temperature and high-pressure saturated steam can be supplemented into the second steam pipeline 302 through the new high-temperature and high-pressure steam input pipeline 50, so that the salt precipitation circulation pipeline 20 can normally operate, and enough secondary unsaturated steam can be provided for the steam compressor 30.
The new high-temperature and high-pressure steam input pipeline 50 is provided with a flowmeter 52, a pressure sensor 53, a temperature sensor 54 and the like, so that the steam parameters in the new high-temperature and high-pressure steam input pipeline 50 are monitored, the excessive or insufficient amount of supplementary steam is avoided, and the steam quality is ensured.
The new high-temperature high-pressure steam input pipeline 50 is provided with an outlet gate valve 55, and the outlet gate valve 55 is used for controlling the on-off of the new high-temperature high-pressure steam input pipeline 50. Namely, when the supplementary steam is required, the outlet gate valve 55 is opened, and when the supplementary steam is not required, the outlet gate valve 55 is closed, thereby preventing the high temperature and high pressure steam generated in the second steam line 302 by the steam compressor 30 from flowing back.
Further, a steam drain pipeline 60 is further arranged at the middle part of the new high-temperature high-pressure steam input pipeline 50. The steam drain pipeline 60 is disposed below the new high-temperature and high-pressure steam input pipeline 50, and is used for draining condensed water condensed on the inner wall of the new high-temperature and high-pressure steam input pipeline 50. It should be noted that, during the transportation process, there is a part of heat loss (the longer the transportation pipeline is, the more the loss is), so that a small amount of steam is condensed into condensed water, and this part of condensed water can be discharged through the steam drain pipeline 60, so as to avoid the phenomenon that the condensed water forms a water hammer in the steam pipe, and the steam transportation pipe vibrates.
Wherein, steam drain line 60 is provided with a steam drain line front stop valve 61, a steam drain line rear stop valve 62, a Y-type filter 63 and a drain valve 64. Further, the steam trap 60 is also provided with a steam trap bypass 601. The two ends of the steam drain bypass 601 are respectively connected to the ends of the steam drain pipeline front stop valve 61 and the steam drain pipeline rear stop valve 62 which are far away from each other. The steam trap bypass 601 is also provided with a steam trap bypass shut-off valve 602.
In general, the front cut-off valve 61 for steam drain pipe and the rear cut-off valve 62 for steam drain pipe are all in a normally open state, and the condensed water sequentially passes through the front cut-off valve 61 for steam drain pipe, the Y-filter 63 (for filtering impurities), the drain valve 64 (for allowing only the condensed water to pass through, and the steam cannot pass through), and the rear cut-off valve 62 for steam drain pipe, which are the normal condensed water discharge flow paths. The purpose of the front cut-off valve 61 of the steam drain pipe and the rear cut-off valve 62 of the steam drain pipe is to facilitate equipment maintenance, for example, the drain valve 64 is damaged, and at the moment, the front cut-off valve 61 of the steam water pipe can be closed, so that the drain valve 64 can be reliably maintained without worrying about steam leakage.
In special cases, when the steam drain pipeline 60 cannot work normally (such as equipment overhaul and maintenance), the bypass stop valve 602 of the steam drain pipe can only be opened to drain water through the bypass, but because the bypass is not provided with the drain valve 64, steam is carried along while the bypass is drained, so that the bypass is only used for emergency, and when the bypass is used, the steam drain bypass stop valve 602 is kept at a certain small opening degree, or after the drain valve is opened, condensed water is drained completely and then is immediately Ma Guanshang.
In one embodiment, the first predetermined location of the second vapor line 302 is provided with a vapor evacuation line 70 in communication with the outside. The steam evacuation line 70 is provided with a first evacuation hand valve 71, a second evacuation hand valve 72, and a relief valve 73. The steam evacuation line 70 is used to evacuate the internal steam, facilitating a rapid decrease in the feed liquid temperature in the salt precipitation tank 21 when the system is shut down.
The safety valve 73 is used for automatically opening the safety valve 73 to discharge the steam in the pipeline when abnormality occurs in the operation process of the system or the steam in the pipeline is overpressured, so that safety accidents are avoided. Here, the first emptying hand valve 71 and the second emptying hand valve 72 generally have the function of opening the hand valve to discharge the steam in the system for cooling down the temperature of the feed liquid in the salt precipitation tank 21 after the system is stopped, or opening the hand valve to discharge the steam for reducing the pressure in the system during the operation under special conditions. The two emptying hand valves, namely the first emptying hand valve 71 and the second emptying hand valve 72, are mainly used for realizing double guarantee because of a certain danger of operation on a steam pipeline.
The transverse tube heat exchanger 10 is provided at a predetermined position with a non-condensable gas discharge line 80 communicating with the outside. The noncondensable gas discharge pipeline 80 is provided with a first noncondensable gas discharge hand valve 81 and a restriction orifice 82. The first non-condensable gas discharging hand valve 81 is used for controlling the on-off of the non-condensable gas discharging pipeline 80. The restrictor orifice 82 is used to regulate the flow of the non-condensable gas discharge line 80 by varying the outlet size. Further, a non-condensable gas discharge bypass 801 is connected in parallel with the non-condensable gas discharge line 80. The non-condensable gas discharge bypass 801 is provided with a second non-condensable gas discharge hand valve 802 and a non-condensable gas adjusting valve 803. The second non-condensable gas discharging hand valve 802 is used to control the on-off of the non-condensable gas discharging bypass 801. The non-condensable gas control valve 803 is used to control the flow of the non-condensable gas discharge bypass 801.
The non-condensable gas discharging pipeline 80 is mainly used for discharging non-condensable gas affecting heat exchange in the transverse tube heat exchanger 10. It should be noted that, because the non-condensing gas in the pipeline can cause great influence on heat exchange of steam, the non-condensing gas needs to be discharged, and the non-condensing gas is discharged in the process of being discharged together with the discharged steam, so the quantity of the discharged steam is controlled through the flow limiting orifice plate 82, and excessive waste heat of the discharged steam is avoided.
In summary, according to the vapor supplementing pipeline 100 based on the evaporation heat exchange system provided by the utility model, the new high-temperature high-pressure vapor input pipeline 50 is connected between the vapor generator 51 and the second vapor pipeline 302, so that when the vapor in the vapor passage 12 serving as the heat source of the horizontal tube heat exchanger 10 is insufficient or the whole system is started in a cold state, the new high-temperature high-pressure saturated vapor can be timely input into the second vapor pipeline 302, the high-salt-content wastewater passing through the feed liquid passage 11 can be ensured to be continuously and stably evaporated and crystallized, or the whole evaporation and crystallization system can be smoothly started in the cold state, and further, the evaporation effect and the treatment efficiency of the whole evaporation and crystallization process are improved.
The present utility model is not limited to the details and embodiments described herein, and thus additional advantages and modifications may readily be made by those skilled in the art, without departing from the spirit and scope of the general concepts defined in the claims and the equivalents thereof, and the utility model is not limited to the specific details, representative apparatus and illustrative examples shown and described herein.
