Description

Technical Field

[0001] The present invention relates to the technical field of smoke dust treatment, and in particular to a dust removal device for dry coke quenching and an exhaust gas treatment system. Background Art

[0002] CDQ is a coke cooling technology used in the coking industry. This technology uses inert gas as a cooling medium to cool the hot coke instead of the traditional water quenching method.

[0003] In the CDQ production process, red coke is pushed out of the coke oven carbonization chamber, loaded into a coke tank car, and then sent to the CDQ device for cooling. However, in the process of transporting coke to the storage or use location by the coke tank car, especially in the device using an open coke tank car for transportation, the smoke generated by the coke during transportation is directly discharged into the atmosphere, causing environmental pollution, and the smoke will also seriously threaten the health of the workers.

[0004] Reference Fig.11 In order to solve the smoke pollution problem during the transportation of coke tank cars, a frameless steel roof is usually installed on the transportation path of the coke tank cars to collect smoke and reduce the escape of smoke.

[0005] However, since there is no supporting truss beam at the bottom of the steel roof, smoke and dust gather on the top of the steel roof. Due to the weight and thermal buoyancy effect of the smoke and dust, the smoke and dust are difficult to be handled by conventional dust removal equipment.

[0006] In view of the above-mentioned related technologies, there is an urgent need for an improved technology for dust removal equipment and exhaust gas treatment system for dry coke quenching, so as to effectively solve the problem of collecting and treating smoke on the top of the steel roof during the transportation of open coke drums. Summary of the invention

[0007] In view of this, the present invention provides a dust removal device and an exhaust gas treatment system for dry coke quenching, aiming to solve the technical problem of collecting and treating smoke on the top of the steel roof during the transportation of open coke drums in the prior art.

[0008] In the first aspect, the present invention provides a dust removal device for dry coke quenching, comprising a plurality of collecting plates and a plurality of exhaust pipes arranged along the long side direction of a steel roof; the collecting plates are arranged in an arch shape, and a channel for smoke to pass through is reserved between two adjacent collecting plates, and the plurality of exhaust pipes correspond one-to-one to the plurality of collecting plates and the exhaust pipes are arranged above the collecting plates; exhaust pipes are arranged on both sides of the long side direction of the steel roof, and the two ends of the exhaust pipe are connected to the two exhaust pipes in sequence; the circumferential side wall of the exhaust pipe is provided with an exhaust groove extending along its own axial direction, and the exhaust groove faces the arc-shaped inner wall of the top of the steel roof, and a rotating part for controlling the rotation of the exhaust pipe around its own axial direction is provided in the steel roof.

[0009] By adopting the above technical solution and setting up a collecting plate, the direction of the smoke flow can be effectively guided, so that the smoke can be more easily collected when passing through the channel between two adjacent collecting plates. The exhaust pipe 1 corresponds to the collecting plate one by one, ensuring that the smoke can be sucked out in time when passing through the channel between two adjacent collecting plates, thereby improving the dust removal efficiency. The design of the exhaust groove enables the exhaust pipe 1 to more effectively suck out the smoke on the top of the steel roof, reducing the accumulation of smoke on the top of the steel roof.

[0010] In addition, the exhaust pipe 1 can rotate. By changing the direction of the exhaust pipe 1, the opening or closing of the exhaust slot can be controlled. For areas with less smoke and dust, the exhaust slot can be closed. For areas with more smoke and dust, more exhaust slots can be opened to improve the exhaust efficiency of the area. When the exhaust volume of the exhaust pipe is fixed, closing part of the exhaust pipe 1 can make the exhaust effect of the opened exhaust pipe 1 stronger and the suction effect better.

[0011] Optionally, the bottom of the interface between the collecting plate and the exhaust pipe 1 is configured as a rounded corner, and an auger blade is fixedly connected to the inner wall of the exhaust pipe 1.

The rounded corners are not easy to form dead corners, making it easier to collect and clean the smoke and dust on the top of the collecting plate. The rounded corner design can also reduce the mutual wear between the collecting plate and the exhaust pipe 1, thereby extending the service life of the device; as the exhaust pipe 1 rotates, the auger blades rotate and can push the smoke and dust on the exhaust pipe 1 and the collecting plate to move downward.

[0013] Optionally, the collecting plate is composed of a horizontally arranged plate one, two symmetrically arranged plates two and two vertically arranged plates three, the two plates two are connected to the two ends of plate one in sequence, the two plates three correspond to the two plates two one by one and plate three is connected to the bottom end of plate two, the top of plate three is located below plate one, the exhaust pipe one is composed of three pipe ones and two pipe twos, the three pipe ones are placed above plate one and the two plates two in sequence, the two pipe twos are rotatably connected to the two plates three in sequence, the circumferential side wall of pipe one is provided with an exhaust groove, the adjacent pipe two is connected to pipe one by a universal joint, and the adjacent two pipe ones are connected by a universal joint; the lower end of pipe two is rotatably connected with a connecting pipe, and the connecting pipe is connected to the exhaust pipe.

[0015] Optionally, the rotating part includes a moving rod slidably connected to the steel roof along the long side direction of the steel roof, the side wall of the moving rod is fixedly connected with a plurality of connecting teeth arranged along the long side direction, and a circumferential side wall of one pipeline 2 is fixedly sleeved with a gear 1, which meshes with the connecting teeth; a support rod is installed on the top of the steel roof, the moving rod is slidably connected to the support rod, a driving motor is connected to the moving rod, a driving wheel is fixedly connected to the output end of the driving motor, and a through groove for the driving wheel to move is opened on the support rod.

[0016] By adopting the above technical solution, through the movement of the moving rod, the connecting teeth are meshed with gear one in turn. When the connecting teeth pass through gear one, gear one is driven to rotate a certain angle, which is convenient for adjusting the direction of the exhaust groove and the switch of the exhaust groove. The setting of the driving motor and the driving wheel makes it convenient to control the moving rod to move back and forth along the long side direction of the steel roof.

[0017] Optionally, the length of the multiple connecting teeth on the moving rod is greater than the diameter of the coke tank on the coke tank car. In the long side direction of the steel roof, when the midpoint of the moving rod corresponds to the midpoint of the coke tank car, the exhaust groove of the exhaust pipe one corresponding to the midpoint of the moving rod faces directly upward, and the exhaust groove of the exhaust pipe one corresponding to the edge of the coke tank car is inclined. In the process from contact to separation between the moving rod and gear one, gear one rotates 360 degrees.

[0018] By adopting the above technical scheme, the exhaust groove located above the midpoint of the coke tank car is opened vertically upward, with the widest exhaust range. The exhaust groove located at the edge of the coke tank car is inclined to facilitate the suction of smoke and dust in the channel, thereby improving the suction efficiency and effect. The gear rotates 360 degrees, causing the exhaust groove to gradually open and then gradually close, so that the exhaust volume of the exhaust pipe can be concentrated on part of the exhaust pipe, thereby improving the suction effect.

[0026] By adopting the above technical solution, when the coke tank car passes by, the second exhaust pipe is driven to rotate so that the exhaust port faces the coke tank car, which is convenient for use and improves the degree of automation of the device.

[0027] In a second aspect, the present invention provides a waste gas treatment system for dry coke quenching, which uses a dust removal device for dry coke quenching proposed in the first aspect to collect and treat smoke on the top of the steel roof.
