A kind of furnace drying method of chimney of the invention, by chimney closed at both ends after, added using moveable burner
Heat, and the smoke tube being connected with blower fan by the setting in chimney, thermal cycle is internally formed using blower fan in chimney, so that
Ensure being heated evenly inside chimney, improve stove quality；During baker, by thermocouple monitoring temperature, and control is fed back to
Cabinet, then the rate of heat addition and heating-up temperature of burner are controlled by regulating gas air inflow such that it is able to effectively control heating
Speed and heating-up temperature, reach the purpose of uniform heating.
In addition, this furnace drying method is heated using portable burner, baker behaviour just can be carried out on the ground in barnyard
Make, it is adaptable to the chimney of various sizes；Burner is using liquefied petroleum gas or natural gas as supplying heat source, it is to avoid power-off can
The trouble that can be caused and duration lose.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing embodiment.
It is as shown in Figure 1 structural representation of the invention,
Reference therein is：Chimney 1, smoke tube 2, blower fan 3, shrouding 4, exhaust outlet 41, burner 5, ignition tube 51, row
Water pipe 6, the direction of arrow represents airflow direction in figure.
As shown in figure 1,
A kind of furnace drying method of chimney, comprises the following steps：
Step one, the lining of chimney 1 are poured, and maintenance terminates, and acceptance(check)；
Thermal Meter verification needed for step 2, baker is finished, and temperature passes through thermocouple monitoring during baker；
Step 3, the axially placed smoke tube 2 inside chimney 1, and smoke tube 2 is connected with blower fan 3, by blower fan 3,
Will be far from the cooler air of combustor end and be delivered to nearly combustor end being heated, due to distal end air pressure, nearly combustor end
Hot-air is gradually pressed onto distal end, forms chimney inside thermal cycle；
Step 4, the two ends of chimney 1 are respectively arranged with shrouding 4, are reserved on an end-plate 4 and send fire hole, and what is connected on burner 5 draws
Fire tube 51 reserves blower fan air outlet and exhaust outlet 41 from sending fire hole to stretch into chimney 1 on another end-plate 4；In the inner side of shrouding 4
Lining ceramic fiber blanket, to avoid heat from being lost in from end；
Step 5, debugging burner 5, it is ensured that tracheae is unobstructed, it is ensured that safety；
Step 6, baker：Input computer heating control program, starts burner 5, and flame size and flame duration are by pre-entering
Program be controlled, according to the automatic baker of drying out curve.
Before baker is carried out, fire-fighting equipment passed examination, and ensure live sufficiency of illumination.
In embodiment, by the heating rate of computer heating control programmed controlled combustion device 5 during baker, and at 80 DEG C extremely
110 DEG C of insulations separate out free water, are then incubated at 200 DEG C to 330 DEG C and separate out the crystallization water.
In embodiment, thermocouple detection temperature information, and temperature information is fed back into computer heating control program, computer heating control journey
Speed, thermostat temperature and constant temperature time that sequence control heats up, temperature deviation are maintained within ± 20 DEG C.
In embodiment, blower fan 3 uses low speed resisting blower, and with burnout-proof, blower fan 3 terminates entirely since baker to baker
Journey must assure that in work, it is ensured that the internal temperature of chimney 1 is uniform, it is ensured that Baker effect.
During baker, chimney 1 is horizontal；The operation of baker can so be facilitated.
In embodiment, exhaust outlet 41 is arranged at the top of the horizontal rear shrouding 4 of the chimney 1.
In embodiment, after chimney 1 is horizontal, the bottom of shrouding 4 sets osculum, and drainpipe 6 is connected on the osculum.
During baker, exhaust outlet 41 need to be opened in good time, and vapor is excluded in time, and only guaranteed vapor is discharged in time,
Just can guarantee that the rising of in-furnace temperature stabilization.And osculum is set can not will become the water of vapor and discharge in time, to ensure
The effect of baker.
In embodiment, burner 5 is using liquefied petroleum gas or natural gas as raw material.Using combustion gas as heat supply raw material,
Trouble and the duration loss being likely to result in can be avoided powering off, hidden danger of leaking electricity is it also avoid.
In order to ensure the accuracy of temperature detection, thermocouple sets one every 5 meters, and thermocouple erects setting, and can not
It is placed directly against on lining.
The furnace drying method of this chimney, is heated using portable burner 5, as long as finding suitable barnyard ground, is become
Furnace operation can be carried out, the method is applied to the chimney of various sizes.During baker, start burner 5 and blower fan 3, using combustion
The heat that burner 5 is produced is heated to the air in chimney 1, meanwhile, the operating of blower fan 3 will be far from the cooler sky of combustor end
Air after gas is delivered to nearly combustor end and is heated by smoke tube 2, and nearly combustor end is heated is due to distal end sky
Atmospheric pressure, moves and enters in smoke tube 2 to distal end, has so just been internally formed a thermal cycle in chimney, makes in chimney 1
Temperature is uniform, stabilization rises.
In heating process, by thermocouple monitoring temperature, and switch board is fed back to, then control by regulating gas air inflow
The rate of heat addition and heating-up temperature of burner 5, reach the purpose of uniform heating.
Highly preferred embodiment of the present invention has been illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
Can depart from the scope of the present invention.
