Efficient dust removal smoke hood for coke pusher of coke oven

Abstract

The invention relates to the technical field of coke oven vehicles, in particular to an efficient dust removal smoke hood of a 7.63 coke oven coke pusher. The invention discloses an efficient dust removal smoke hood for a coke pusher of a coke oven. Side smoke baffles are additionally arranged on the two sides of the coke pusher; (2) using a fixed smoke hood at the top of the coke pusher; (3) smoke dust at the top of the Nth coke pushing oven number and the top of the oven door of the (N-2) th coke pushing oven number is collected in an interface valve mode; and (4) the fixed smoke hood of the coke pusher is a hollow smoke hood with an interlayer, and holes are only formed in the local part of a smoke dust accumulation area. Negative pressure is uniformly distributed according to a smoke dust accumulation area through the interlayer type smoke hood of the coke pusher, and 100% collection of smoke dust in the span of the coke pusher is guaranteed.

Description

technical field [0001] The invention relates to the technical field of coke oven vehicles, in particular to a 7.63 high-efficiency dust removal hood for coke oven pushing vehicles. Background technique [0002] Large coke ovens over 7m have become the standard equipment in the current coking industry. With the large-scale development of coke ovens, the distance between the coke oven push car and the coke oven body, the distance between the operating platform and the smoke hood on the top of the coke push car, and the span on both sides of the vehicle have also increased, resulting in the coke push process. The diffusion range of the smoke and dust increases, and the difficulty of collecting the smoke and dust increases. The four major 7.63m coke oven vehicles are designed by German Schalke Company. The vehicles have a high level of automation and have fully automatic operation functions. However, there are problems of smoke and dust collection in the essential environmental...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is achieved in the following way: a high-efficiency dust removal hood for coke oven pushing car, (1) adding side smoke baffles on both sides of the coke pushing car , driven by a hydraulic cylinder, opened before the coke pushing operation, retracted before the coke pushing car moves, to solve the problem that the natural ventilation in front of the coke pushing car affects the diffusion of smoke and dust; (2) Use a fixed smoke hood on the top of the coke pushing car, The machine-side fixed smoke baffle is installed between the furnace columns on the upper part of the machine-side furnace roof to cover the entire coke oven machine side. When the coke pusher moves, the fixed smoke hood of the coke pusher and the machine-side fixed smoke baffle pass through The U-shaped groove installed on the top of the furnace column on the side of the machine is sealed to keep the top space within the span of the coke pushing car fully covered; (3) the top of the Nth coke pushing oven and the top of the door of the N-2th coke pushing oven The dust is collected through the interface valve, that is, on the outer edge of the top of the furnace column on the machine side, the height is from the furnace top to the service car track hanger beam, a fixed baffle is installed, and a hole is opened in the center, and it is fixed on the coke pushing car Install a telescopic interface valve at the position directly above the coke pusher rod and at the position of the N-2th coke pusher under the type smoke. Open when working; (4) The fixed fume hood of the coke pusher is a hollow fume hood with an interlayer, which only partially opens holes in the dust accumulation area, and distributes the negative pressure area of ​​the entire fume hood evenly according to the dust accumulation area, so that the inside of the fume hood All the smoke and dust are in the negative pressure area to improve the smoke and dust collection effect
