Top-loading coke oven smokeless coal charging device

Abstract

The invention discloses a smokeless coaling device of a top-charging coke oven. The smokeless coaling device comprises a flashboard device, and a coal charging sleeve, wherein the flashboard device is arranged at the upper part of the coal charging sleeve. The smokeless coaling device is characterized in that a built-in flashboard device is arranged inside the flashboard device; the coal charging sleeve comprises an upper sleeve, a fixed sleeve, a movable sleeve, a sleeve sealing device, and a fire hole sealing device; a fire hole sealing base matched with the fire hole sealing device is arranged on the plane of the fire hole; an outer sleeve capable of axially stretching is also arranged; the outer sleeve is sleeved outside the fire hole sealing device; the upper end of the outer sleeve is connected with the movable sleeve; a work surface butted with the plane of the fire hole is formed at the lower end of the outer sleeve; a drive device guide rack is arranged at the side of the coal charging sleeve; and a movable sleeve drive device for driving the movable sleeve to axially move up and down and an outer sleeve drive device for driving the outer sleeve to axially stretch are connected with the drive device guide rack. By adopting the device, effective sealing of the fire hole of the coal charging furnace is achieved, a raw coke oven gas generated in the coal charging process enters a gas collecting pipe system through an ascend pipe, and the air quantity requirements on a dust removal system also can be reduced.

Description

technical field [0001] The invention relates to the technical field of top-loading coke ovens, in particular to a smokeless coal charging device for top-loading coke ovens, which realizes the sealing of raw gas at the mouth of the top-loading coke oven when charging coal, and passes the raw gas generated during the coal charging process. The rising pipe enters the air collecting pipe system to solve the pollution problem. technical background [0002] During the coal charging process of the top-loading coke oven, a large amount of raw gas overflows from the coal charging furnace mouth, which seriously pollutes the environment. In order to solve the environmental pollution caused during the coal loading process, it is generally solved by dust removal methods (vehicle dust removal, ground station dust removal). Because raw gas has the characteristics of high temperature, flammability and a large amount of coal tar, the basic form of dust removal is through mixing. A large num...

Problems solved by technology

[0003] In order to solve the problem of a large amount of raw coal gas overflowing from the furnace mouth when charging coal in the top-loading coke oven, the present invention provides a smokeless coal charging device for the top-loading coke oven. The raw coal gas generated during coal loading enters the gas collecting pipe system through the riser pipe, which solves the problem of pollution source from the source and can greatly reduce the air volume requirements of the dust removal system
