Abstract

The invention discloses a treatment tower for flue gas from boilers, and belongs to the technical field of treatment equipment for waste gas. The treatment tower comprises a tower. A flue gas inlet, a flue gas outlet and a liquid outlet are formed in the tower, a plurality of heat absorbing tube stacks, a suspended particle filter screen, a sulfur dioxide filter screen and spray nozzles are arranged in the tower, the flue gas can flow in the tower in a retracing manner under the effects of the heat absorbing tube stacks, the suspended particle filter screen and the sulfur dioxide filter screen are arranged to form layers, and the spray nozzles are positioned below the sulfur dioxide filter screen, are arranged on the side walls of the tower, are communicated with a liquid delivery pipeline and face the inside of the tower; the heat absorbing tube stacks are communicated with a circulating pipeline via water inlets and steam and water outlets of the heat absorbing tube stacks, and the circulating pipeline is arranged on the outside of the tower and is connected with a pump and a steam and water separator. The treatment tower has the advantage that the problem of air pollution due to the fact that flue gas from existing boilers is directly exhausted to the air can be solved by the aid of the treatment tower.

Description

Boiler smoke treating column
Technical field
The present invention relates to waste gas treatment equipment technical field, especially a kind for the treatment of column for boiler smoke.
Background technology
Boiler is the heat energy utilizing fuel or other energy, water or dielectric heating, export the plant equipment that heat energy supplies people's production and living needs, what in its production process of existing boiler, its fuel combustion produced contains flue dust, the flue gas of sulfur dioxide and carbon dioxide etc. is all directly be disposed in air by chimney, its exhaust gas temperature is generally not less than 180 DEG C, reach as high as 250 DEG C, this high-temperature flue gas discharge not only causes a large amount of thermal waste, the atmosphere pollution that simultaneously also to cause with flue dust and sulfur dioxide be representative, result shows after deliberation, the concentration of Sulfur Dioxide In The Atmosphere often increases by 1 times, general mortality rate increases 1l%, TSP concentration often increases by 1 times, and general mortality rate increases by 4%, and the excessive emissions of carbon dioxide can cause global warming phenomenon, therefore a kind for the treatment of apparatus of convenient and practical boiler smoke is badly in need of.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of boiler smoke treating column, and this treating column can solve that existing boiler smoke is in line causes air-polluting problem in the air.
In order to solve the problem, the technical solution adopted in the present invention is: this boiler smoke treating column, comprise the tower body offering gas approach, exhanst gas outlet and liquid outlet, be provided with flue gas is turned back in described tower body suspended particulate filter screen, sulfur dioxide filter screen that multiple endothermic tube groups of flowing, level arrange in described tower body and be positioned at and be arranged on the nozzle towards tower body be communicated with on described tower body sidewall and with liquid-transport pipe-line below described sulfur dioxide filter screen; Described endothermic tube group is exported by its water inlet and carbonated drink and is connected with the circulating line of steam-water separator with the pump that is connected be arranged at outside described tower body.
In technique scheme, technical scheme can also be more specifically: the cold medium in described endothermic tube group is water, and the liquid in described liquid-transport pipe-line is ammoniacal liquor, and described suspended particulate filter screen is full glass microporous filter membrane; Described sulfur dioxide filter screen is made up of absorbent charcoal material; Described endothermic tube group is regularly arranged and the multiple U-tube communicated of connecting.
Further: steam-water separator to offer water inlet, carbonated drink import, delivery port and venthole, described carbonated drink import is connected with the carbonated drink outlet of described endothermic tube group, and described delivery port is connected with the water inlet of described pump.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, owing to being provided with suspended particulate filter screen and sulfur dioxide filter screen in tower body, and be provided with the nozzle connecting liquid-transport pipe-line below sulfur dioxide filter screen, during work, suspended particulate in flue dust and sulfur dioxide are first by effective filtering, then the ammoniacal liquor in liquid-transport pipe-line sprays to flue dust by the collecting carbonic anhydride in flue dust, obtaining clean gas enters in the air, free from environmental pollution, ensure that people's is healthy; And its carbonic hydroammonium generated can utilize again, has saved resource.
2, due to be provided with in tower body wherein have water and flue gas is turned back the endothermic tube group of flowing in tower body, it extends the flowing time of flue gas, makes the heat in high-temperature flue gas effectively be absorbed by U-shaped ducted water the mixture that changes steam and water into fully and flow out recycling.
3, owing to being provided with steam-water separator, steam and water export by steam-water separator respectively, and steam is used effectively, and water again enter endothermic tube group carry out heat absorption circulation, saved water resource.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
Boiler smoke treating column shown in Fig. 1, comprise the tower body 1 offering gas approach 1a, exhanst gas outlet 1b and liquid outlet 1c, be provided with in tower body 1 make flue gas turn back in tower body 1 flowing multiple endothermic tube groups 21, level arrange suspended particulate filter screen 6, sulfur dioxide filter screen 4 and be positioned at the nozzle 9 towards tower body 1 being arranged on below sulfur dioxide filter screen 4 and being communicated with on tower body 1 sidewall and with liquid-transport pipe-line 8; Endothermic tube group 21 is regularly arranged and the multiple U-tube communicated of connecting, endothermic tube group 21 is exported by its water inlet and carbonated drink and is connected with the circulating line 2 of steam-water separator 3 with the pump 5 that is connected be arranged at outside tower body 1, steam-water separator 3 offers water inlet 3a, carbonated drink import 3b, delivery port 3c and venthole 3d, carbonated drink import 3b is connected with the carbonated drink outlet of endothermic tube group 11, and delivery port 3c is connected with the water inlet of pump 5; Cold medium in endothermic tube group 21 is water, and the liquid in liquid-transport pipe-line 8 is ammoniacal liquor, and suspended particulate filter screen 6 is full glass microporous membrane filtration; Described sulfur dioxide filter screen 4 is made up of absorbent charcoal material.
During work, flue gas passes through suspended particulate filter screen 7 by prefiltration, the most suspended particulate of filtering, turn back in tower body again and flow to sulfur dioxide filter screen 6 place, sulfur dioxide by sulfur dioxide filter screen 6 filtering in flue gas, the ammoniacal liquor then in liquid-transport pipe-line sprays to flue dust by the collecting carbonic anhydride in flue dust; Obtaining clean gas enters in the air from exhanst gas outlet, and its carbonic hydroammonium liquid generated flows out from liquid outlet to be recycled, heat simultaneously in high-temperature flue gas is effectively absorbed cooling by U-shaped ducted water, and water changes the mixture of steam and water into and arrives steam-water separator after flowing out, steam and water export by steam-water separator respectively, steam is used effectively, and water again enter endothermic tube group carry out heat absorption circulation, saved water resource.
