Abstract
The utility model relates to a circulation flue gas cleaning device, which is composed of an exhaust gas recovery tank, a draught fan, an exhaust gas processor, a purifying barn, a lime pit and a circulation pump. The exhaust gas recovery tank is provided with a water cooling chamber in which an air duct is arranged; the exhaust gas processor is provided with a heating wire and catalyst; the purifying barn is provided with a spray header and an adsorption layer; an air exhaust opening of the upper end of the purifying barn is provided with an exhaust gas purifier with a heating wire and a circulation pipe for the secondary purification of the tail gas. The circulation flue gas cleaning device has the de-dusting function, the de-sulfurizing function and the smoke abatement function, and can decrease the height of the chimney; moreover, the utility model has the advantages of simple structure, low cost, small ground occupation, electricity saving, water saving, no secondary pollution, etc.
Description
This practicality relates to the purifier of all kinds of boiler chimneys of a kind of purified treatment and smelting furnace chimney institute exhaust gas discharged, belongs to the useless flue gases purification field of chimney.
At present, the useless gas cleaning of chimney is handled in the prior art, the general method that generally adopts Electrostatic Treatment, the method of these Electrostatic Treatment waste gas, dust discharge amount contained in the waste gas can only be reduced, and can not reduce or except the harmful substances such as sulphur in the waste gas, so its waste gas purification treatment effect is poor.
The purpose of this utility model is: provide a kind of can dedusting again can sulphur removal and the circulating smoke eliminator of smoke abatement.
The utility model is to constitute like this: it is by waste gas recycling can (1), air-introduced machine (2), exhaust processor (3), cleaning position (4), Calcified pond (5), circulating pump (6) is formed, waste gas recycling can (1) is connected with air-introduced machine (2) by pipeline, the gas outlet of air-introduced machine (2) is connected with exhaust processor (3) by pipeline, exhaust processor (3) is connected with tubaeform gas outlet (7) in the cleaning position (4) by pipeline, Calcified pond (5) is positioned over the outlet below of cleaning position (4), valve (8) is housed in the outlet of cleaning position (4), circulating pump (6) is contained on the residual water pipe road (9) of cleaning position (4), water cooling chamber (10) is arranged in waste gas recycling can (1), breather line (11) is housed in water cooling chamber (10), the water inlet pipe (12) and the outlet pipe (13) that communicate with water cooling chamber (10) are arranged on waste gas recycling can (1), heating wire (14) and catalyst (15) are housed in exhaust processor (3), spray header (16) is equipped with in top in cleaning position (4), adsorption layer (17) is arranged in the middle, in the exhaust outlet of cleaning position (4) upper end, the catalytic converter (18) that has heating wire is housed and on its exhaust outlet, is equipped with and reclaim tank connected tail gas double purification circulation pipe (19), the air inlet pipe (20) that is connected with chimney is arranged at the front end of waste gas recycling can (1) with waste gas.
The utility model compared with prior art, the function that not only has dedusting, but also have the function of sulphur removal and smoke abatement, and the utility model can reduce the height of chimney, it also have simple in structure, cheap, floor space is little, power saving, water-saving, do not cause advantages such as secondary pollution.During use, open an aspirating hole (22) earlier in the position, middle and lower part of processed chimney (21) and slightly locate out to open a vent (23) in the top on the opposite of aspirating hole (22), air inlet pipe (20) is connected on the aspirating hole (22), and the water source received respectively on water inlet pipe (12), the spray header (16), and in Calcified pond (5), add an amount of lime and get final product.When in the chimney (21) flue gas being arranged, its flue gas is drawn in the waste gas recycling can (1) by air-introduced machine (2), and by the breather line (11) in the water cooling chamber (10), flue gas enters exhaust processor (3) by air-introduced machine (1) after being cooled and lowering the temperature, after passing through catalyst (15) after heating wire (14) heating in exhaust processor (3), sulphur cigarette in its flue gas is converted to the sulfur trioxide that is easy to water-soluble or lime white, its sulfur trioxide is dissolved in by tubaeform gas outlet (7) in the water of cleaning position (4) lining and (port of tubaeform gas outlet (7) should be immersed in the water during use), the residue flue gas enters by the tail gas double purification circulation pipe (19) on the exhaust outlet by adsorption layer (17) with after having the catalytic converter (18) of heating wire again again and carries out in the waste gas recycling can circulating the second time, wherein has small part flue gas after treatment to enter in the atmosphere by the exhaust outlet of cleaning position (4).
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment of the present utility model: waste gas recycling can (1) can adopt sheet metal to make, air-introduced machine (2), circulating pump (6) all adopts the finished product of selling on the market, waste gas recycling can (1) is connected with air-introduced machine (2) by pipeline, the gas outlet of air-introduced machine (2) is connected with exhaust processor (3) by pipeline, exhaust processor (3) is connected with tubaeform gas outlet (7) in the cleaning position (4) by pipeline, Calcified pond (5) is positioned over the outlet below of cleaning position (4), in the outlet of cleaning position (4), load onto valve (8), circulating pump (6) is contained on the residual water pipe road (9) of cleaning position (4), in waste gas recycling can (1), make the water cooling chamber (10) that can adorn water, and in water cooling chamber (10), load onto tens of breather lines (11), on waste gas recycling can (1), install the water inlet pipe (12) and the outlet pipe (13) that communicate with water cooling chamber (10), in exhaust processor (3), load onto heating wire (14) and catalyst (15), can adopt vanadic anhydride to make catalyst (15), spray header (16) is loaded onto in top in cleaning position (4), use activated carbon as adsorption layer (17) in the middle, in the exhaust outlet of cleaning position (4) upper end, load onto the catalytic converter (18) that has heating wire and on its exhaust outlet, load onto with waste gas and reclaim tank connected tail gas double purification circulation pipe (19), at the front end of waste gas recycling can (1) air inlet pipe that an energy is connected with chimney is installed and (20).
