The existing treatment method of the waste gas is to directly ignite the carbonized waste gas to ensure that harmful substances in the carbonized waste gas completely react after combustion; however, since the exhaust gas from carbonization contains a large amount of high carbon molecules, the exhaust gas is not only difficult to burn completely after ignition, but also accompanied by strong black smoke. On one hand, the black smoke can further influence the combustion effect of the carbonized waste gas, on the other hand, the treatment difficulty of the carbonized waste gas is increased, so that even if the waste gas is subjected to combustion supporting through various modes or additives, a small amount of unburned and complete toxic gas and untreated clean smoke gas can still be mixed in the discharged waste gas, and the environment is seriously damaged. Therefore, a carbonized exhaust gas treatment apparatus capable of completely treating flue gas and toxic gas is required.

Compared with the prior art, the carbonization waste gas can be ignited through the primary combustion chamber, most toxic gas in the waste gas is burnt and removed after the carbonization waste gas is burnt, smoke is generated, the carbonization waste gas can be sprayed through the matching of the gas passage, the spray head and the guide plate in the dust removal chamber, carbon particles in the waste gas can be mixed with water drops and then flow into the bottom of the box body, and the treatment and the separation of the smoke are realized; meanwhile, after the water flows in, the water is gathered at the bottom of the box body and the mesh plate is immersed, so that the waste gas discharged from the primary combustion chamber can pass through the accumulated water and the mesh plate to enter the gas passing channel, bubbles generated when the waste gas is discharged are divided by the mesh plate, and the contact area of the waste gas and the accumulated water is increased, so that part of carbon particles in the waste gas can be adsorbed by the accumulated water firstly, the removal difficulty of a subsequent spraying process is reduced, and the treatment effect of the smoke is improved; after waste gas is treated by the dust removal chamber, the waste gas is mixed with fuel gas in the secondary combustion chamber for combustion, so that toxic gas and carbon particles which are not removed in the waste gas can be completely combusted, and the emission of smoke and harmful gas is avoided. Therefore, the utility model discloses can handle the flue gas in the carbomorphism waste gas and toxic gas completely.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. Carbonization furnace carbonization waste gas complete combustion device constitutes as shown in figure 1, includes that the pipeline connects gradually once combustion chamber 1, clean room 2 and postcombustion chamber 3, and the outside of once combustion chamber 1 is connected with waste gas and advances pipe 4, and the outside of postcombustion chamber 3 is connected with the gas respectively and advances pipe 5 and waste gas exit tube 6, clean room 2 includes box 7, has polylith mesh board 8 by going up side by side distribution in the box 7, and the hole site on the adjacent mesh board 8 is the dislocation distribution, and top one side of box 7 is equipped with gas channel 9, and gas channel 9's bottom is equipped with guide plate 10, and gas channel 9's top is equipped with shower nozzle 11, and gas channel 9's end connection postcombustion chamber 3 walks.

A check valve is arranged between the primary combustion chamber 1 and the dust removal chamber 2, a waste water outlet pipe 12 is arranged at the bottom of the dust removal chamber 2, and the waste water outlet pipe 12 is externally connected with a sewage treatment device.

Igniters are arranged in the primary combustion chamber 1 and the secondary combustion chamber 3.

And a conveying pipe connected with the gas outlet channel 9 is arranged on one side of the secondary combustion chamber 3, and an igniter and a gas inlet pipe 5 in the secondary combustion chamber 3 are both positioned in the middle positions of the waste gas outlet pipe 6 and the conveying pipe.

The utility model discloses a theory of operation: the waste gas generated after carbonization is firstly sent into the primary combustion chamber 1 and is directly combusted by an igniter, so that most toxic gas in the waste gas is eliminated after combustion, and meanwhile, high-carbon molecules in the waste gas form carbon particles with small particle size in the combustion process, thereby generating black smoke. The burnt waste gas enters the dust removing chamber 2 from the bottom of the box body 7 and passes through the moisture accumulated in the box body 7 to enter the gas passing channel 9; when the waste gas passes through the mesh plate 8 with different hole positions, the waste gas is cut to form a plurality of small bubbles, and meanwhile, the small bubbles are adsorbed by accumulated water, so that part of carbon particles in the waste gas are adhered to water and separated from the waste gas. After the waste gas enters the gas channel 9, the water is sprayed out in a foggy manner through the spray head 11, so that the smoke is adhered again by the water mist and falls into the guide plate 10, thereby realizing secondary clearing of the smoke and effectively improving the clearing effect of the smoke. Rivers continue to get into box 7 along guide plate 10 and form ponding, and bottom ponding is discharged along waste water exit tube 12 simultaneously, makes ponding can keep lasting the change, avoids the stifled hole problem that the excessive carbon particle matter content caused in the ponding. The waste gas after the dust removal chamber 2 is treated enters the secondary combustion chamber 3 through the conveying pipe, meanwhile, the gas and the air are mixed by the gas inlet pipe 5 in the secondary combustion chamber 3 and then are fed into and combusted, so that the waste gas is combusted together with the waste gas in the secondary combustion chamber 3, carbon particles and harmful gas which are not completely removed in the waste gas are completely combusted, and the pollution of the discharged waste gas to the environment is avoided.
