Coke oven coal feeding port online uncovering system and method

Abstract

The invention relates to a coke oven coal feeding port online uncovering system and method. The online uncovering system is an independent control unit and is linked with an existing riser system and a coal charging car, an uncovering device travels along a fixed rail and automatically travels to a certain oven number according to a remote instruction, and an oven cover is opened and flatly placed by utilizing an electromagnet principle; and the oven cover can run to other areas for operation and residence or continue to be opened, and can also return to a certain furnace number according to a remote instruction, and the furnace cover is put into a corresponding coal feeding opening again. According to the invention, remote control and unmanned operation can be realized, and manual furnace cover opening and closing operation at the top of the existing coke oven can be completely replaced; and ordered empty burning of coaling residual graphite and secondary coke can be realized, coke oven refractory masonry damage caused by excessive empty burning of a local carbonization chamber can be avoided, the problem that raw coke oven gas is not burnt and escapes in the process of opening an ascending pipe cover can also be eliminated, unorganized emission of VOCs in the coking production process is reduced, environmental pollution is reduced, and the coke oven operation environment is improved.

Description

technical field [0001] The invention relates to coke oven technology, in particular to an on-line uncovering system and method for a coke oven coal charging port. Background technique [0002] Each carbonization chamber of the top-loading coke oven has 4-5 coal charging ports. The furnace cover is opened during coal charging operation, and the furnace cover is closed after coal charging. The opening and closing of the furnace cover is carried out by the coal charging car. During the dry distillation process of coking coal in the coke oven, the volatile matter is continuously precipitated to become raw gas, which passes through the high-temperature refractory masonry and enters the bridge pipe to cool and then collects in the gas collecting pipe. Raw coal gas is mainly composed of multi-component hydrocarbons, which are cracked at high temperature to form carbon black, mixed with coal dust during coal charging, and graphite is deposited in rough parts such as coke oven body a...

Problems solved by technology

[0006] In the existing technology, except that the coal loading car uses the cover removal machine to open the cover, it is all carried out manually, and there are problems such as poor working environment for workers, safety risks of man-machine combination, and difficulty in synchronizing the operation and the riser cover.

Restricted by the characteristics of coking production, maintenance operations such as the coal inlet on the top of the coke oven and the riser pipe need to be manually opened. For a long time, there has been no significant breakthrough in domestic and foreign technologies, which restricts the realization of smart coking
