Description

Tail gas incinerator of high-combustion-rate carbonization furnace

Technical Field

The utility model relates to an burn burning furnace, especially a high combustion rate retort tail gas burns burning furnace.

Background

In the production process of the activated carbon, the carbonization furnace tail gas incinerator in the prior art is a straight-barrel type incinerator, and the tail gas is insufficiently combusted in the tail gas combustion process of the straight-barrel type incinerator. The effective combustion space of the straight-tube type incinerator is small, the periphery of the incinerator is in contact with the outside, the heat of tail gas in the incinerator is permeated into refractory bricks, so that the flue gas is insufficiently combusted around the incinerator, and the tail gas incinerator body of the existing carbonization furnace is long, but the incineration temperature is low and can only reach about 900 ℃ at most.

SUMMERY OF THE UTILITY MODEL

To current carbomorphism stove tail gas incinerator burning waste gas not abundant, burning programming rate is slow, technical defect such as combustion efficiency low, the utility model provides a furnace body length is short, and burning programming rate is fast, a high combustion rate carbomorphism stove tail gas incinerator that combustion temperature is high.

The technical effect of the utility model is realized through following mode:

a high-firing-rate carbonization furnace tail gas incinerator, comprising: the furnace body, the resistant firebrick of step on the furnace body, by the S curved burning tunnel that resistant firebrick formed, install the waste gas air inlet that lets in carbomorphism stove tail gas in the furnace body bottom for let in the air vent in burning tunnel with furnace body outside air, install the combustor in the outside UNICOM burning tunnel of furnace body, install the aiutage in the furnace body top connection burning tunnel, install the draught fan on the aiutage.

Furthermore, the refractory brick is an alumina hollow ball heat-insulating refractory brick. The highest combustion temperature of the carbonization furnace tail gas incinerator of the prior art can only reach about 900 ℃, so firebrick generally adopts high-alumina insulating brick or clay insulating brick, the utility model discloses a high combustion rate carbonization furnace tail gas incinerator's incineration temperature can easily burn 1300 ℃, consequently, has used the higher alumina hollow sphere insulating brick of insulating temperature.

Further, the path of the combustion tunnel is five combustion paths from top to bottom. The path of the combustion tunnel is designed to be turned back up and down, so that the combustion space is enlarged, and the flue gas in the tail gas incinerator is combusted more fully.

Further, the burners are installed at the exhaust gas inlet and at all the air through holes. The burner is arranged at the air through hole, and is beneficial to supporting combustion by air.

Further, a smoke detection sensor is installed at the outlet of the exhaust funnel. The flue gas detection sensor detects whether the combusted flue gas reaches the exhaust standard in real time, and comprises SO₂、NO、NO₂、H₂S and dustParticle sensors, and the like. The smoke detection sensor is not limited to the above-described ones.

Furthermore, a cooling water tank is arranged at the bottom of the exhaust funnel, and comprises a water inlet pipeline for water entering from the bottom of the box body and a water outlet pipeline for water drainage from the top of the box body. Because the combustion temperature of the flue gas in the incinerator is very high, the temperature of the discharged flue gas is reduced by installing the cooling water tank at the bottom of the exhaust funnel, and therefore the draught fan installed on the exhaust funnel and the flue gas detection sensor at the outlet of the exhaust pipe are protected from being influenced by high temperature.

The utility model designs the combustion chamber into the S-shaped combustion tunnel, so the utility model has a furnace body with a length greatly shortened compared with the furnace body in the prior art.

The utility model discloses a high combustion rate retort tail gas burns burning furnace, burn in the stove and set up a plurality of burning routes of turning back from top to bottom through resistant firebrick for the flue gas carries out the S in the stove and bends, has enlarged the space of burning, the utility model discloses a high combustion rate retort tail gas burns burning furnace can easily burn 1200 ℃ -1300 ℃ with the interior temperature of stove.
