Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing equipment for coke intercepting vehicles, in particular to a soft sealing device for dust removal on the coke side of a coking plant. Background Art
[0002] A coking plant is a specialized facility specializing in the production of metallurgical coke, as well as the smelting, processing, and recycling of coking products. It consists of a coal preparation workshop, coking, recycling, tar processing, benzene processing, desulfurization, and wastewater treatment plants. The coking process primarily involves coal preparation, coking, quenching, chemical product recovery, and refining. Coke, coal gas, tar, and other by-products are produced from coal and other materials. Coking refers to the process of carbonizing and coking organic matter. Coking includes five processes: delayed coking, kettle coking, open-hearth coking, fluidized coking, and flexicoking.
[0003] The coke quenching car is an auxiliary equipment for large coke ovens, and the coke guide grid is an auxiliary equipment for the coke quenching car. The coke quenching car generally runs on rails on the coke side of the coke oven and is mainly used to open and close the coke oven door. The coke guide grid is installed on the coke quenching car to guide the hot coke in the coke oven. During the production process, the coke guide grid moves with the coke quenching car to the coke oven door. The coke guide grid is aligned with the side of the carbonization chamber where the coke is pushed out. On the coke side, the coke pushed out of the carbonization chamber, which is around 1000 degrees Celsius, is guided into the coke quenching car. When pushing the coke, the coke guide grid of the coke quenching car is connected to the coke oven frame. Because it is a connection between iron parts, it cannot be completely seamless. The gap between the front of the coke guide grid and the oven door frame causes smoke and dust to escape, causing dust and toxic and harmful gas emissions. This not only has a certain impact on the health of on-site workers, but also damages the ecological environment.
[0004] As the country pays more attention to green production, higher requirements are put forward for the production process. The coke guide grid of the coke intercepting car that is still widely used is no longer suitable for the current environmental protection requirements. Therefore, it is necessary to solve the gap at the interface between the front of the coke guide grid and the furnace door frame to achieve the effect of reducing the unorganized emission of dust and toxic and harmful gases. In response to the above problems, the utility model provides a coking coke side dust removal soft sealing device, which mainly installs a soft seal on the side where the coke guide grid and the furnace frame are connected. When the coke intercepting car moves to the coke outlet, the coke guide grid and the coke oven can form a relatively sealed space, which can effectively prevent smoke and toxic and harmful gases from leaking from the gap between the coke guide grid and the coke oven frame, thereby reducing air pollution. Utility Model Content
[0005] The utility model aims to provide a soft sealing device for dust removal on the coke side of a coke oven, so as to solve the problem that when the coke is pushed out of the coke oven, a large amount of smoke and dust overflows from the coke oven, causing air pollution.
[0006] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a soft sealing device for coking coke side dust removal, comprising a coke oven, a coke guide grid and a dust hood, the dust hood being located on one side of the coke oven, the top of the dust hood being connected to a dust removal duct, a dust removal fan being provided in the dust removal duct, a first mounting plate being detachably connected to the side where the coke guide grid docks with the oven frame of the coke oven, a plurality of first steel wire brushes being provided on the first mounting plate, the first steel wire brushes being in contact with the oven frame of the coke oven.
[0007] The working principle of the utility model is as follows: when pushing coke, first open the coke oven door, then start the coke intercepting car, and the coke intercepting car drives the coke guide grid to slide on the track on one side of the coke oven to the coke oven frame, then connect the coke guide grid to the coke oven frame, so that the wire brush on the coke guide grid just fits against the coke oven frame, so that the coke guide grid and the coke oven form a relatively sealed space, when the coke is pushed out, the dust is sucked into the dust removal pipeline by the dust removal fan in the dust removal pipeline, and finally enters the dust removal tower for unified purification and discharge.
[0008] The beneficial effect of the present invention is that: the present invention realizes the sealing between the coke guide grid and the coke oven by arranging a wire brush on the coke guide grid. Compared with the coke guide grid of the coke intercepting car that was widely used before, this design can form a relatively sealed space between the coke guide grid and the coke oven when the coke guide grid moves with the coke intercepting car to the coke oven door and the coke oven frame, preventing smoke and dust from escaping from the gap between the coke guide grid and the coke oven frame, which not only reduces the harm to the health of on-site workers, but also reduces air pollution.
[0009] Option 2 is the preferred option of the basic option. The dust hood is detachably connected to a second mounting plate on one end close to the coke guide grid. A number of second steel wire brushes are provided on the second mounting plate. The steel wire brushes on the dust hood can narrow the gap between the dust hood and the quenching car, thereby further reducing smoke and dust emission.
[0010] Option three is the preferred option of the basic option. The first mounting plate is connected to the focus guide grid bolts, and the second mounting plate is connected to the dust cover bolts, which makes it easy to replace the damaged wire brush.
[0011] Option 4 is the preferred option of the basic option. The dust hood is an umbrella-shaped hood, which can better capture and collect smoke and dust.
[0012] Option 5 is a preferred option of the basic option. The first wire brush and the second wire brush are arranged in a honeycomb shape. The honeycomb shape arrangement makes the wire brushes more densely arranged, preventing smoke and dust from overflowing from the gaps.
[0013] Option six is the preferred option of the basic option. The first wire brush and the second wire brush are both made of chromium alloy steel. Chromium alloy steel has good high temperature resistance, oxidation resistance and corrosion resistance, and can work for a long time in a high temperature environment.
