specific Embodiment approach 2

[0012] Embodiment 2. The difference between this embodiment and the pre-spraying system of a coke oven ground dedusting station described in Embodiment 1 is that the outer wall of the pre-spraying material inlet side of the pre-spraying pipeline 11 is coated with an asphalt layer 10.

specific Embodiment approach 3

[0013] Embodiment 3. The difference between this embodiment and the pre-spraying system of a coke oven ground dedusting station described in Embodiment 1 or 2 is that the outer wall of the pre-spraying material outlet side of the pre-spraying pipeline 11 is fixed with concrete Layer 12.

specific Embodiment approach 4

[0014] Specific embodiment four, a kind of coke oven ground dedusting station pre-spraying method based on specific embodiment one, its method is:

[0015] When the coke oven is working, the coke powder produced by the coke oven is sent into the ash storage bin, and the coke powder enters the ash storage chamber through the ash storage bin. It is blown into the coke oven through the pre-spraying pipeline to realize the pre-spraying of the coke oven ground dust removal station.

[0016] During the pre-spraying process of the coke oven ground dust removal station, the butterfly valve is opened to allow the coke powder to enter the ash tanker through the screw ash unloader.

Abstract

The invention provides a pre-spraying system and a pre-spraying method of a coke oven ground dedusting station and relates to a pre-spraying system and a pre-spraying method of a coke oven dedusting station, solving the problem that the existing pre-spraying system is severely influenced by a temperature and a pre-spraying material so as to result in a poor pre-spraying effect. The pre-spraying method comprises the following steps: feeding the coke powder generated when the coke oven works into a dust putting cabin and feeding into the dust storing chamber; and blowing the coke powder entering into the dust storing chamber into a dust collecting pipeline through the pre-spraying pipeline by utilizing the compressed air, thereby achieving the pre-spraying of the coke oven ground dedusting station. The pre-spraying system and the pre-spraying method are suitable for the pre-spraying process of the coke oven ground dedusting station.

Description

technical field [0001] The invention relates to a pre-spraying system and a pre-spraying method of a coke oven dedusting station. Background technique [0002] The existing pre-spraying system is a peripheral independent pre-spraying chamber. This kind of pre-spraying system needs to be kept warm and maintained when the temperature is low. The pre-spraying material used is white ash, which is expensive and easy to agglomerate. The influence of temperature and pre-spraying materials is serious, and the pre-spraying effect is poor; moreover, the existing feeding method is tank truck or manual feeding, which is labor intensive and operating costs are high. Contents of the invention [0003] The invention aims to solve the problem that the existing pre-spraying system is seriously affected by temperature and pre-spraying materials, resulting in poor pre-spraying effect, thereby providing a pre-spraying system and a pre-spraying method of a coke oven ground dust removal station...
