Abstract
Description
Technical field:
[0001] The utility model belongs to the field of coal coking production, in particular to a smoke removal device at a coke oven mouth in coal coking production. Background technology:
[0002] The coking industry is one of my country's important industries. It has developed rapidly in recent years, but the serious environmental pollution problems caused by coking production have also become increasingly prominent. During the coke oven production process, large amounts of intermittent smoke and dust are emitted into the atmosphere during the coal loading, coke pushing, and coke discharge processes. For example, the smoke leaking from the coke oven side is generated during the coke discharge process of the top-loading coke oven. The existing technology uses a dust collection hood above the coke outlet. Although this method can collect smoke, the smoke absorbed by the hood is mostly upward smoke, while the smoke diffused to the left and right sides of the coke outlet cannot be absorbed in time. In particular, in windy weather, a large amount of smoke and dust will still be emitted, causing serious pollution to the environment and harming the health of on-site workers. Utility model content:
[0003] The purpose of the utility model is to provide a smoke removal device for a coke oven mouth in coal coking production, and to overcome the deficiencies of the above-mentioned prior art, which effectively solves the existing problem of environmental pollution caused by smoke in coal coking production.
[0004] The content of the utility model: A smoke removal device for a coke oven mouth in coal coking production, comprising a smoke collecting hood, wherein a strip dust suction duct is connected to the top wall of the smoke collecting hood, the smoke collecting hood is installed at the top of the side door frame of the coke oven machine, strip auxiliary smoke collecting ducts are vertically arranged on both sides of the smoke collecting hood, the top end of the strip auxiliary smoke collecting duct is connected to the strip dust suction duct, a smoke inlet is opened on the inner side wall of the strip auxiliary smoke collecting duct, and a concave air guide plate is matched and installed on the outer side wall of the strip auxiliary smoke collecting duct.
[0005] Furthermore, an oil storage tank is installed at the bottom opening of the strip-shaped auxiliary smoke collecting duct, an oil drain pipe is connected to the bottom end of the oil storage tank, and a valve is installed on the oil drain pipe.
[0006] Furthermore, the oil storage tank is in the shape of an inverted trapezoid.
[0007] Furthermore, the smoke inlet is inclined downward.
[0008] Furthermore, a smoke guide plate inclined downward is provided above the smoke inlet, and the smoke guide plate is fixedly mounted on the side wall of the strip-shaped auxiliary smoke collecting duct.
[0009] Furthermore, a connecting ear plate is installed on the outer side wall of the strip-shaped dust suction duct.
[0010] The beneficial effects of the utility model are as follows: smoke generated by the coke oven mouth can be effectively collected through the smoke collecting hood and the strip-shaped auxiliary smoke collecting ducts connected on both sides thereof, thereby preventing the smoke diffused from the coke oven mouth from polluting the environment. Description of the drawings:
[0011] Figure 1 This is the main view of the utility model;
[0012] Figure 2 for Figure 1 Sectional view of AA in the middle;
[0013] Figure 3 It is a partial cross-sectional view of the main view of the utility model;
[0014] In the figure, there are 1 smoke hood, 2 dust suction ducts, 3 auxiliary smoke collection ducts, 4 smoke inlets, 5 concave air guide plates, 6 oil storage tanks, 7 oil drain pipes, 8 smoke guide plates, and 9 connecting ear plates. Specific implementation method:
[0015] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:
[0016] like Figures 1 to 3 As shown, a smoke removal device for a coke oven mouth in coal coking production comprises a smoke collecting hood 1, the top wall of which is connected to a strip dust suction duct 2, the smoke collecting hood 1 is installed at the top of the side door frame of the coke oven machine, strip auxiliary smoke collecting ducts 3 are vertically arranged on both sides of the smoke collecting hood 1, the top of the strip auxiliary smoke collecting duct 3 is connected to the strip dust suction duct 2, a smoke inlet 4 is opened on the inner side wall of the strip auxiliary smoke collecting duct 3, and a concave shaped smoke collecting duct 4 is matched and installed on the outer side wall of the strip auxiliary smoke collecting duct 3. shaped air guide plate 5, an oil storage tank 6 is installed at the bottom opening of the strip-shaped auxiliary smoke collecting duct 3, the bottom end of the oil storage tank 6 is connected with an oil drain pipe 7, a valve is installed on the oil drain pipe 7, the oil storage tank 6 is an inverted trapezoidal shape, the angle of the smoke inlet 4 is inclined downward, and a downward-slanting smoke guide plate 8 is provided above the smoke inlet 4, the smoke guide plate 8 is fixedly installed on the side wall of the strip-shaped auxiliary smoke collecting duct 3, and a connecting ear plate 9 is installed on the outer side wall of the strip dust suction duct 2.
[0017] Specifically, the smoke generated by the coke oven mouth can be effectively collected through the smoke collecting hood 1 and the strip-shaped auxiliary smoke collecting ducts 3 connected on both sides thereof, thereby preventing the smoke spreading in the left and right directions of the coke oven mouth from polluting the environment.
[0018] During actual use, the smoke rising from the side opening of the coke oven machine is collected by the smoke collecting hood 1, while the smoke emitted to the left and right is effectively blocked and collected by the strip auxiliary smoke collecting ducts 3 arranged on the left and right sides of the coke oven machine opening; in this process, the smoke is sucked into the strip auxiliary smoke collecting duct 3 through the smoke inlet 4, and the smoke sucked into the strip auxiliary smoke collecting duct 3 is merged with the smoke in the strip dust suction duct 2 and finally transported to the dust removal and filtration system for filtration; the downwardly inclined smoke inlet 4 and the smoke guide plate 8 are conducive to the smoke being quickly sucked into the strip auxiliary smoke collecting duct 3; the smoke in the strip auxiliary smoke collecting duct 3 is The tar gathered on the wall flows into the lowered oil storage tank 6 for temporary storage. The valve on the oil drain pipe 7 can be opened regularly to discharge and recycle the tar to avoid waste of resources and environmental pollution. The two strip auxiliary smoke ducts 3 can not only collect smoke, but also act as wind shields, thereby preventing the wind blowing from the left and right sides of the coke oven mouth from blowing away the smoke, which is beneficial for the strip auxiliary smoke ducts 3 to collect the smoke, and the concave wind guide plate 5 further guides the wind blocked by the strip auxiliary smoke duct 3 to the outside of the oven mouth. By installing bolts on the connecting ear plate 9, the strip auxiliary smoke duct 3 can be quickly connected and fixed to the side wall of the coke oven mouth.
[0019] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
