Abstract

A coke oven coke oven smoke burning furnace comprises a furnace body and a burner, wherein the lower end of the furnace body is arranged with a smoke inlet and a gas distributing opening, while the upper end is arranged with an air outlet, the burner is arranged between the smoke inlet, the distributing opening and the furnace body. The burner comprises a cylinder casing, a baffle plate, a gas head, a fire gas distributing tube, and a fire gas tube. The baffle plate is axially arranged at the lower portion of the casing, which one side is opposite the smoke inlet. The lower end of the casing is arranged with a gas distributing opening. Another side of the baffle plate is arranged with the upward gas head which lower end is connected with the fire gas tube and extruded outside the casing, while the casing at the side is arranged with the fire gas distributing tube. The baffle plate of the utility model can avoid smoke to directly blow fire head, to avoid fire being extinguished. The utility model comprises a plurality of fire heads and gas distributing cylinders to disperse fire uniformly, improve firing and burning effect. The heat storage material in the furnace body can improve the temperature of the furnace body and the stay time of smoke in furnace, to realize complete burning, thereby improving treatment effect. The utility model can ignite easily via an automatic igniter.

Description

Coke oven flue dust combustion furnace

Technical field

The utility model relates to environmental protection equipment, and particularly a kind of coke oven flue dust combustion furnace is used for the flue dust that the coke oven furnace roof is discharged when the coal processing of burning.

Background technology

The match board head of the burner of existing this combustion furnace is directly drawn from the watch box inwall, and duration and degree of heating is concentrated and the flue dust stream that very easily advanced mouth is blown out duration and degree of heating; The manual firing is very inconvenient; Flue dust time of staying in body of heater is short, and it is not high enough to heat, so burning is insufficient, treatment effect is bad.

Summary of the invention

The purpose of this utility model just provides a kind of flame of igniting and is difficult for extinguishing, and can light a fire automatically, and duration and degree of heating disperses, the coke oven flue dust combustion furnace of sufficient combustion.

The technical solution of the utility model is: comprise body of heater, burner, into mouth and air distribution port are arranged in the body of heater lower end, there is the gas outlet upper end, burner is advancing between mouth and distribution and the body of heater, described burner comprises barrel-type casing, demarcation strip, combustion gas head, the gas-distribution pipe of igniting, the Gas Pipe of igniting, demarcation strip axially places lower housing portion, and the one side faces toward into mouth, and there is air distribution port this housing lower end; At the opposite side of demarcation strip is up combustion gas head, and the lower end of this combustion gas head connects ignites Gas Pipe and pass housing, at this side body gas-distribution pipe of igniting.

Described burner shell is a cylindrical shape; Demarcation strip is an arc, and its concave side advances mouth to described; The combustion gas cephalic par is a gradually-reducing shape, and the connected Gas Pipe of igniting has the 3-8 root.

Comprise also being connected in described sub-cylinder of igniting between Gas Pipe and the air supply header that each Gas Pipe of igniting connects the gas outlet on the sub-cylinder.

Also comprise the heat-storing material that places in the body of heater.

Also comprise the igniter that is arranged on described burner top and the observation window of body of heater bottom.

Demarcation strip of the present utility model has avoided flue dust directly to blow match board head, makes duration and degree of heating be difficult for extinguishing; A plurality of match board heads and sub-cylinder make duration and degree of heating dispersion, even, have improved and have ignited and combustion efficiency; Heat-storing material in the body of heater has improved furnace body temperature and the stop burning time of flue dust in stove, and it is fully burnt, and has improved treatment effect greatly; Automatic ignition device has made things convenient for igniting.

The specific embodiment

Referring to Fig. 1-Fig. 3, the utility model comprises body of heater 1, burner 2, and into mouth 3 and air distribution port 4 are arranged in the lower end of body of heater 1, and there is gas outlet 5 upper end.Burner 2 comprises cylindrical shell 21, demarcation strip 22, convergent combustion gas 23, the ignite gas-distribution pipe 24 and the Gas Pipe 25 of igniting, demarcation strip 22 is convexly curved, and vertically place the bottom of housing 21, its recessed side one is advanced mouth 3 facing to housing 21 1 sides, at the opposite side of demarcation strip 22 are up combustion gas 23, its lower end connects ignites Gas Pipe 25 and passes housing 21, the gas-distribution pipe 24 of igniting in the bottom of this side body 21.Air distribution port 4 is connected in the lower end of housing 21.

The combustion gas of this embodiment 23 and the connected Gas Pipe 25 of igniting have 5.For the flame that makes each combustion gas 23 is in optimum state, also be provided with sub-cylinder 7 between Gas Pipe 25 and the air supply header 6 igniting, also can regulate throughput at the control valve of each Gas Pipe 25 of igniting to the combustion gas supercharging by string, thereby guarantee that the combustion gas that is fed is a barotropic state, it is safer to work.

Also in body of heater 1, be provided with heat-storing material 8.

Above described burner 2, be provided with electronic ignition device 9 and be provided with observation window 10 in body of heater 1 bottom.So that the combustion case in the observation stove.

Of the present utility modelly advance mouth 3 and is connected with the gas pipeline that coke oven is discharged flue dust, air distribution port 4 is used to provide the required oxygen that burns.
