Description

Technical Field

[0001] The utility model relates to a coke quenching anti-splashing device and belongs to the technical field of coke quenching equipment. Background Art

[0002] Coke quenching is an important step in the coal coking process, and its main purpose is to cool the refined red-hot coke. There are two main ways to quench coke, namely, quenching in the furnace and quenching outside the furnace. Modern horizontal chamber coke ovens generally use quenching outside the furnace, and quenching outside the furnace is further divided into dry quenching and wet quenching. Among them, wet quenching is to use water to spray directly on the high-temperature coke to cool it down. The wet quenching process is simple, but it also pollutes the environment. Under the impact of water flow, each quenching will cause coke to splash outside the truck bed, causing waste of resources and environmental pollution. In addition, coke is easy to accumulate on the top end of the truck bed, which falls during transportation within the factory and is difficult to clean. In addition, the mist generated by quenching will also escape and cause air pollution. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a coke quenching anti-splashing device, which aims to effectively reduce the coke splashing and water mist diffusion during wet quenching, thereby significantly reducing resource waste, environmental pollution and subsequent cleaning workload.

[0004] The coke quenching anti-splash device described in the utility model comprises a quenching cover arranged on the track of the quenching bucket, the quenching cover is higher than the quenching bucket, a spray pipe is arranged inside the quenching cover, and the spray pipe is connected to the quenching water supply pipe; a circle of steel brushes is arranged below the outer periphery of the quenching cover, and the steel brushes can contact the top end surface of the quenching bucket when the quenching bucket is moving.

[0005] The spray pipe supplies water through the quenching water supply pipe to achieve uniform spray cooling of high-temperature coke. The steel brush can effectively block the coke to prevent it from splashing outside the bucket during quenching. And when the quenching bucket moves on the track, the steel brush can scrape off the coke residue on the top of the bucket to prevent it from accumulating and falling during transportation. The steel brushes are distributed between the quenching cover and the quenching bucket, making the quenching space semi-enclosed, which can greatly reduce the diffusion of water mist during the quenching process.

[0006] Among them, the height of the steel brush is less than or equal to the distance between the bottom of the quenching hood and the top of the quenching bucket.

[0007] The circle of steel brushes under the outer periphery of the quenching cover is divided into multiple sections, each section of the steel brush can be disassembled, which is easy to maintain and replace after wear.

[0008] Specifically, a circle of horizontal ribs is welded on the edge of the quenching hood, and studs are welded on the top of the brush holder plate of the steel brush. The top of the studs passes through the ribs and is fixed by nuts to ensure that the steel brush can be firmly fixed on the quenching hood.

[0009] In order to effectively control the mist generated during the quenching process, a negative pressure air duct is connected to the top of the quenching hood.

[0010] Preferably, the outlet end of the negative pressure air duct is connected to an air purification device to ensure that the mist can be effectively purified before being discharged, thereby greatly reducing pollution to the environment.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. Reduce coke splashing and resource waste: The steel brush can effectively block coke and effectively avoid coke splashing caused by direct impact of water flow, thereby significantly reducing resource waste.

[0013] 2. Reduce environmental pollution: On the one hand, the direct pollution to the surrounding environment is reduced due to the reduction of coke splashing; on the other hand, the negative pressure air duct and the connected air purification device further ensure that the mist is effectively purified before discharge, greatly reducing air pollution.

[0014] 3. Reduce the workload of subsequent cleaning: The design of the steel brush effectively prevents the accumulation of coke on the top of the truck bed and reduces the possibility of coke falling during transportation within the factory, thereby greatly reducing the workload of subsequent cleaning.

[0015] 4. Easy to maintain and replace: The steel brush is divided into multiple sections, each of which can be disassembled, so that the steel brush can be easily and quickly maintained and replaced after it is worn, reducing maintenance costs.

[0016] 5. Optimize the working environment: Improve the safety of operation by reducing splashing and mist diffusion, and provide a better working environment for workers. BRIEF DESCRIPTION OF THE DRAWINGS
