Description

Technical Field

[0001] The utility model relates to the technical field of coke oven production equipment, in particular to a ramming coke oven head smoke treatment device. Background Art

[0002] A ramming coke oven refers to a side-loading coke oven that uses the ramming method to load coal for coking. Its furnace head with a coal loading port is located on its side. However, when loading coal or discharging coke, the furnace door of the furnace head must be open, which will cause a large amount of smoke and dust to escape from there. The main harmful substances in this smoke and dust are coal dust, raw coal gas and tar smoke, which are highly polluting to the environment and harmful to human health. Therefore, existing ramming coke ovens usually add a dust collection hood above the furnace head, and use a ground dust removal station to directly extract and remove dust when loading coal or discharging coke.

[0003] For example, the utility model patent with patent number CN211170577U discloses a device for processing smoke on the coke side of a coke oven, including a conical smoke hood, a branch pipe, a guide pipe, a dust collecting main pipe and a ground dust processing device; the coke oven has several carbonization chambers and a coke oven controller connected to each carbonization chamber, and each carbonization chamber has a carbonization chamber door. A conical smoke hood is arranged at a height h above each carbonization chamber door, and h does not exceed 1m; a branch pipe is arranged at the top of the gathering mouth of each conical smoke hood, and an automatic valve is arranged in each branch pipe. The dust collecting main pipe is arranged horizontally above the guide pipe and is connected to the top of each guide pipe. The middle part of the dust collecting main pipe is connected to the ground dust processing device through a dust removal pipeline; the ground dust processing device includes a variable frequency fan; an arc-shaped guide pipe is arranged at the top of each branch pipe.

[0004] There are at least the following problems in the prior art: first, the dust removal method is single, and the dust removal effect cannot reach the designed dust suppression rate of 95% or even lower, causing serious environmental pollution; second, even if the variable frequency fan is turned on to the maximum air volume, the stove smoke will still overflow to a greater or lesser extent, affecting the environment. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model develops a ramming coke oven stove smoke treatment device, which can not only treat stove smoke by combining a variety of dust removal and dust suppression methods, but also inhibit smoke diffusion and reduce smoke overflow, thereby effectively improving the stove smoke treatment effect and improving air quality.

[0006] The technical solution of the utility model to solve the technical problem is: a ramming coke oven smoke treatment device, including a coke oven, a plurality of furnace doors are arranged on the front side of the coke oven, and also includes a dust collecting device and a dust suppression spray device. The dust collecting device is arranged on the top of the coke oven through a bracket. The dust collecting device includes a dust collecting dry pipe and a plurality of dust collecting pipes. One end of the dust collecting pipe is connected to the dust collecting dry pipe, and the other end of the dust collecting pipe is arranged above the furnace door through the bracket. The dust suppression spray device includes a plurality of nozzles and a plurality of spray pipes. The water inlet of the nozzle is connected to the spray pipe, and the nozzle is arranged on the outer side wall of the dust collecting pipe.

[0007] As an optimization, each group of spray pipes is equipped with at least one group of nozzles, which can form a single-point control and multi-point interlocking spray mode, with the spray area coverage reaching more than 98%, and the spray droplets being 4000 microns, achieving mist compatibility and ensuring less unorganized discharge of materials.

[0008] As an optimization, the nozzle is arranged on the outer wall of the dust collecting pipe close to the furnace door, which can improve the dust suppression effect.

[0009] As an optimization, the dust suppression spray device also includes a main pipe, and the spray pipes are connected to the main pipe. By setting the main pipe, clean water can be provided for several groups of spray pipes.

[0010] As an optimization, the dust collecting device also includes a fan, which is connected to the dust collecting main pipe, and the dust suppression spray device also includes a water pump, and the water outlet of the water pump is connected to the main pipe. By setting the fan, the smoke from the stove head can be sucked; by setting the water pump, clean water can be pumped to the nozzle for spraying.

[0011] As an optimization, the dust suppression spray device further comprises a solenoid valve, which is arranged on the spray pipe. By arranging the solenoid valve, single furnace spray control can be achieved.

[0012] As an optimization, a control device is also included, and the output end of the control device is connected to the input end of the solenoid valve, water pump and fan respectively. By setting the control device, the vehicle-mounted dust removal system can be interlocked, and the delayed start and stop and pressure control can be set. The dust suppression spray device can be started in advance before the dust collection device is started, and the spraying is delayed after the dust removal is completed, so as to further suppress the spread of smoke and dust.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By setting up a dust collecting device, the furnace smoke can be collected when the coke oven is loading coal and discharging coke. Each dust collecting pipe can correspond to each furnace door, and the furnace smoke of each furnace door can be uniformly collected into the dust collecting main pipe for easy transportation; by setting up a dust suppression spray device, the diffusion and overflow of smoke can be suppressed. The spray pipe can transport clean water to the nozzle, and the nozzle sprays, and its coverage area is 1㎡, so as to cooperate with the dust collecting device to perform double dust removal and dust suppression. The utility model can not only combine a variety of dust removal and dust suppression methods to control furnace smoke, but also suppress the diffusion of smoke and reduce smoke overflow, effectively improve the treatment effect of furnace smoke, and improve air quality.
