Description

Technical Field

[0001] The utility model relates to the technical field of transportation equipment, in particular to a clean transportation equipment for red coke from a coke oven. Background Art

[0002] Coke dry quenching is a facility that uses the waste heat of coke produced in coke ovens to generate electricity, thereby achieving energy conservation and environmental protection. The temperature of coke produced in coke ovens is about 1000±50℃, and special red coke transportation equipment is required to transport it to coke dry quenching.

[0003] In the prior art, red coke transportation equipment generally includes: coke tank, coke tank trolley, electric locomotive, and dry coke quenching elevator. The coke tank is used to store the hot red coke unloaded from the coke oven; the coke tank trolley is used to place the coke tank; the electric locomotive is used as a driving vehicle to drive the coke tank trolley to the dry coke quenching elevator shaft; the dry coke quenching elevator is used to lift the coke tank from the coke tank trolley and move it to the top of the dry coke quenching, and return the coke tank to the coke tank trolley after the red coke is unloaded.

[0004] During the process of transporting red coke from the coke oven to the dry quenching coke, the coke drum is open, and smoke is emitted in an unorganized manner during this process, which increases the coke burning loss, causes environmental pollution, and shortens the life of the coke drum.

[0005] After the coke tank trolley travels to the CDQ lifting shaft, the coke tank cover is placed on the coke tank by the hoist. The coke tank cover is equipped with explosion-proof holes. Since the coke tank and the coke tank cover are deformed by heat, the coke tank cover cannot be completely sealed. Therefore, during the transportation of the coke tank to the top of the CDQ, flames, smoke and dust overflow, causing environmental pollution.

[0006] After the coke tank is transported to the top of the dry coke quenching by the elevator, the bottom gate under the coke tank is opened, and the red coke is unloaded into the dry coke quenching through the loading device. The prior art has dust removal pipes on both sides of the loading device for dust removal during the unloading process of the red coke. When the red coke is unloaded and the dry coke oven cover is not closed, the flame and smoke overflow through the open oven mouth, causing environmental pollution. In view of this, we propose a coke oven red coke clean transportation equipment. Utility Model Content
