Description
Technical field
The present invention relates to a kind of flue tail gas multistage combustions to purify efficient treatment process.
Background technique
Flue gas, tail gas are the product after burning, in flue gas and tail gas there are also a large amount of flue dust, dust, carbon monoxide,
The gases such as carbon dioxide, nitrogen dioxide, sulfur dioxide can be to environment and air if these gases are directly discharged in air
Weight causes serious pollution, and a large amount of acid rain is caused to land, and the mode of existing processing exhaust gas is to use high altitude discharge, this
Processing mode cannot be inherently eliminated pollution of the discharge to air of exhaust gas.
Summary of the invention
The purpose of the present invention is to provide a kind of flue tail gas multistage combustions to purify efficient treatment process.
A kind of flue tail gas multistage combustion of technical solution of the present invention purifies efficient treatment process, including sequentially connected secondary
Burner, flue dust adsorbent equipment, residual heat using device, level-one waste gas recovering device, second level waste gas recovering device, washing lotion device
With Vapor adsorption device, inlet exhaust gas, air intlet, exhaust outlet and burner are connected on the after burner, it is described
It is provided with flue dust adsorption stuffing in flue dust adsorbent equipment, is provided with heat absorption filler in the residual heat using device, described one
The discarded recyclable device of grade includes level-one alkali liquid tank and second level alkali liquid tank, and it includes acid solution tank that the second level, which discards recyclable device, described
It is provided with washing lotion filler in washing lotion device, is provided with Vapor adsorption filler in the Vapor adsorption device.
Preferably, the inlet exhaust gas on the after burner is connect with flue dust adsorbent equipment, on the air intlet
It is connected with air blower.
Preferably, the flue dust adsorption stuffing and Vapor adsorption filler are ANTHRACITE FILTER MEDIA.
Preferably, the residual heat using device and the interior heat absorption filler being arranged of washing lotion device and washing lotion filler are
Water.
Preferably, strong base solution and weak caustic solution, acid solution are respectively set in the level-one alkali liquid tank and second level alkali liquid tank
Weak acid solution is set as in tank.
The technology of the present invention the utility model has the advantages that
A kind of flue tail gas multistage combustion of technical solution of the present invention purifies efficient treatment process, utilizes after burner
Gas not sufficiently combusted in tail gas is burnt again, guarantees the tail gas completely burned of discharge, avoids that carbon monoxide occurs
Deng poisoning or explosion phenomenon, using the flue gas particle in flue dust adsorbent equipment initial absorption tail gas, residual heat using device realizes tail
The utilization of heat in gas, level-one waste gas recovering device and second level waste gas recovering device are utilized respectively in lye and acid solution removal tail gas
Sour gas, obtain can emission, washing lotion device and Vapor adsorption device remove respectively can residual acid in emission
Liquid and steam, so that completely arrive at can discharge standard for tail gas.
Specific embodiment
For convenient for those skilled in the art understand that technical solution of the present invention, now does further technical solution of the present invention
It is bright.
A kind of flue tail gas multistage combustion purification efficient treatment process, including sequentially connected after burner, flue dust

Acid solution.
A kind of flue tail gas multistage combustion of this law technical solution purifies efficient treatment process, will using after burner
The unburned gas sufficiently generated such as carbon monoxide etc. carries out full combustion in tail gas, avoids the occurrence of the pernicious gases such as carbon monoxide
Poisoning or explosion, while it being also convenient for neutralization reaction and absorption followed by tail gas, flue dust adsorbent equipment utilizes ANTHRACITE FILTER MEDIA
Soot dust granule etc. in tail gas is absorbed, does not influence the discharge of the gas of each ingredient in tail gas, residual heat using device is filled
Point using the heat in tail gas, reduce the use of electric energy or fuel, while also reducing the temperature of tail gas, it is subsequent convenient for tail gas
It absorbs and reaction, level-one waste gas recovering device is divided into level-one alkali liquid tank and second level alkali liquid tank, level-one alkali liquid tank and second level alkali liquid tank
It is inside respectively set to strong base solution and weak caustic solution, sour gas in tail gas, second level exhaust gas are fully absorbed by two-stage alkali liquid tank
Recyclable device is the acid solution tank for being provided with weak acid, and the residual lye in gas is discharged via alkali liquid tank using weak acid ingredient draws,
Washing lotion device and Vapor adsorption device remove respectively can residual acid solution and steam in emission so that completely arrive at can for tail gas
Discharge standard.
Technical solution of the present invention is exemplarily described to invention, it is clear that the present invention implements not by above-mentioned side
The limitation of formula improves as long as using the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out, or without changing
