Upright coke-oven transition purification receiving and extinguishing technique and equipment

Abstract

The invention provides a vertical device which has the technology of coke receiving and quenching by translation and purification of a coke oven. The equipment consists of a horizontal car for coke receiving and a drum for coke quenching. The horizontal car for coke receiving consists of systems of coke receiving and coke discharging while the drum for coke quenching consists of a tower body, a water pump station, and a spray system of three directions. The invention is characterized in that the system of coke receiving consists of a storehouse for coke receiving and a horizontal moving device. The storehouse for coke receiving has the structure of a box with grids, and the structure consists of two-side walls, a motherboard, and plates on the two sides. The motherboard is not integrated with the two-side walls, and a gradient is in front and back. The plate of the storehouse for coke receiving which is close to the coke oven is rotatable and is not integrated with the two-side walls.The invention can greatly reduce or avoid the dust pollution resulted from the process of the coking discharging in the coking plant and is applied to the coking discharging system which has a new coke oven as well as the reconstruction of a old coking discharging system. The reconstruction expense is low and the environment protection benefit is distinct.

Description

technical field [0001] The invention relates to a coking and quenching process and matching equipment for avoiding dust pollution in the coking process of a vertical coking oven. Background technique [0002] The so-called vertical coke oven refers to a coke oven in which the ratio of the height to the width of the coal cake in the coking chamber of the coke oven is much greater than 1:1, generally above 6:1. [0003] In China and the world's steel industry and coking industry, the vertical coke oven has always been the dominant furnace type, accounting for more than 95% of the total. At present, the current coke discharge process of the current vertical coke oven is used in conjunction with the coke stop car and the coke quenching car. When the coke is discharged, the coke stop car is aligned with the furnace mouth, responsible for protecting the coke from being skewed, so that the coke can be poured smoothly. It falls on the coke quenching car, and it is this falling proc...

Problems solved by technology

At present, the current coke discharge process of the current vertical coke oven is used in conjunction with the coke stop car and the coke quenching car. When the coke is discharged, the coke stop car is aligned with the furnace mouth, responsible for protecting the coke from being skewed, so that the coke can be poured smoothly. It falls on the coke quenching car, and it is this falling process that produces a large amount of dust, causing pollution to the coking plant and the surrounding air environment, which has become one of the main pollution items in all pollution projects in the coking industry. It is a headache for the coking industry to be completely solved
