Abstract
A purge gas system apparatus comprising: a combustion apparatus, a heat exchanger for cooling flue gas discharged from the combustion apparatus, a blower for introducing the gas drawn from the heat exchanger into a foaming soot separator disposed in a water tank so that soot carried by the flue gas is "scraped" by water as the flue gas exits from the separation foaming, and purified exhaust gas is discharged from a chimney disposed above the water tank to prevent air pollution.
Description
The present invention relates to clarification system for flue gas.The flue gas that general spontaneous combustion equipment such as boiler or incinerator burning are discharged later directly enters in the atmosphere and will cause serious air pollution because of dust, flue dust, soot and other organic matters that is suspended in the gas.Waste gas after burning is as being introduced into an electrostatic precipitator, though the dust of being carried secretly in the waste gas can be removed by electrostatic precipitator, the higher meeting of its installation and maintaining cost increase company is the financial burden of medium-sized and small enterprises particularly.And the used heat of flue gas is not just introduced the equipment that also may damage deduster in the deduster except that wasting energy if be recovered.
This case inventor is invention the application's diving-type clarification system for flue gas in view of the shortcoming of habitual combustion apparatus.
The purpose of this invention is to provide a kind of clarification system, this system comprises: a combustion apparatus, the flue gas that one heat exchanger is discharged in order to cooling spontaneous combustion equipment, the gas that one air blast will be taken out in heat exchange is introduced a foaming dust separator that stays under water in a tank, its contained flue dust can " be struck off " by water institute when flue gas was left by separator, purified waste gas is released from the chimney row who is located on the tank again, thereby has prevented air pollution.
Brief description of drawings:
Fig. 1 is a system diagram of the present invention;
Fig. 2 is the front sectional elevation of heat exchanger of the present invention;
Fig. 3 is the side view of this heat exchanger;
Fig. 4 represents foaming dust separator of the present invention;
Fig. 5 is the side view of this foaming dust separator.
Consult each accompanying drawing, system of the present invention comprises: a combustion apparatus 1, as boiler, burner etc.; One cooling device, 2, one air blasts, 3, one foaming dust separating devices, 4, one purified gas blowdown stacks 5, and a flue dust collecting device 6.
The flue gas that spontaneous combustion equipment 1 is discharged is delivered to cooling device 2 by the main chimney 11 that contains valve 111 through shunt valve 12.But shut-off valve 111 when stack gas cleaning is handled.
Foaming dust separating device 4 comprises: a foaming tank 41, one foaming dust separators 42, are arranged on the emptying gas chimney that tank 41 tops are connected with exhaust outlet 43, and one connects the discharge pipe 45 of the overfall 44 of tank top.This foaming tank 41 is poured water to horizontal plane 40, so that flush with overfall 44.This foaming dust separator 42 stays under water under the water surface 40 of tank 41, and it comprises that the ducted body 421 of a sealing is connected with air blast 3, is Fig. 4, the cylinder type shown in 5 approximately; Many smoke exhaust holes 422 are established in ducted body 421 controls, and on the flange cover of its openend 424 blind plate 423 are arranged.Blind plate 423 is removable so that remove flue dust or the mud that is deposited in the ducted body 421.
Flue dust collecting device 6 comprises: an adjacency foaming tank 41 is positioned at the dust-precipitator 61 of separator discharge pipe 45 belows, one places the filter bag 62 in the dust-precipitator 61 to fly at the water surface in order to collection, the flue dust that goes out from overfall 44 overflows, carbon powder etc., one is located at dust-precipitator 61 bottoms and contains the delivery pipe 63 of valve 631, one stillpot 64 receives waste water that delivery pipes 63 discharge and surplus dirt and receives from 411 sludge discharged of sludge pipe that are located at tank 41 bottom band valves 412, and one second circulating pump 65 is used for clear water with stillpot 64 tops through pipe 651, valve 625 pumped back foaming tank 41.
When device of the present invention was operated, the hot flue gases of combustion apparatus 1 was blown in the foaming dust separator 42 by air blast 3 after the cools down of cooling device 2, and flue gas is overflowed by smoke exhaust holes 422 foaming.Flue dust such as the dust of being carried secretly in the gas, carbon powder, particulate are scraped by current when the gas vesicle leaves aperture 422, purified gas is discharged by the top chimney then, the lightweight flue dust is suspended on the water surface, be collected in the bag 62 by overfall 44 outflows, the heavy flue dust then is deposited on tank 41 bottoms, and mud is then removed away by bottom land.
Cooling water is after interchanger 21 heat exchange, warm water store in the groove 23 in case the preheating of raising water for boiler with or be made for the usefulness of other warm water source, cooling water also can be from the water source 22 continues spray and enters in the interchanger 21 heat exchange warm water later and then directly discharged by interior pipe 232 and use; Also can be by interchanger 21, groove 23, pump 234 circulate to cool off in the forced circulation mode and give discharge until reaching the uniform temperature rear.
The pure qi (oxygen) treating apparatus that the present invention is better than habitually practising be following some:
1. the flue gas of cooling off is struck off the flue dust of carrying secretly in the underwater in the bubbling mode, and installation cost is low, operates smooth and easyly, and the maintenance problem is few.
2. hot gas reclaims and sprinkles heat, energy savings earlier with cooling heat transferring.
Unlike water scrubber need add high-pressure hydraulic pump hydro-peening flue dust, and directly bubbling mode dedusting in water can be saved the electric energy that high-pressure pump consumes.
4. need not additionally to install metal screen, and directly with foaming mode dedusting in the water.
