Embodiment 1

[0032] A tail gas impurity treatment device, such as figure 1 As shown, it includes an exhaust tube 2 arranged at the exhaust port of the coating kettle and a scraper 1 arranged inside the exhaust tube 2 for scraping off the attachments on the inner wall of the exhaust tube 2, and the exhaust The cylinder 2 has a circular cylindrical structure, and the end of the exhaust cylinder 2 away from the exhaust port is provided with a first motor 3, and the scraper 1 is driven by the first motor 3 to rotate around the axis of the exhaust cylinder 2, and the exhaust cylinder 2 An exhaust outlet 4 communicating with the inside of the exhaust tube 2 is also provided on the outer wall of the exhaust tube.

[0033] Through a tail gas impurity treatment device with the above structure, when the green coke reacts in the coating kettle, the tail gas generated during the reaction will move to the exhaust port and enter the exhaust pipe 2. After a long period of use, the exhaust Attachments wi...

Embodiment 2

[0040] A clad kettle, such as figure 1 with figure 2 As shown, the coating kettle includes a cylinder 7 and the above-mentioned tail gas impurity treatment device, the cylinder 7 is provided with a feed inlet 5, a discharge port 6, an exhaust port and a stirring device arranged in the cylinder 7, The above-mentioned tail gas impurity treatment device is arranged at the exhaust port.

[0041] When using the coating kettle, the user needs to preheat the cylinder 7 to the feeding temperature, then open the feed port 5, put the material into the cylinder 7 through the feed port 5, and then put the feed port 5 Close and enter the reaction stage; during the reaction stage, the material in the cylinder 7 will produce water, volatile matter, tar and other substances, and these substances will move to the tail gas impurity treatment device with the tail gas; During long-term use, the moisture, volatile matter and tar produced by the material will adhere to the exhaust tube 2 and cau...

Abstract

The invention belongs to the technical field of coating kettles, and particularly relates to a tail gas impurity treatment device and a coating kettle. The tail gas impurity treatment device comprisesan air exhaust cylinder, a scrap plate and a first motor, wherein the scrap plate is used for effectively scraping the attaching matters at the inside wall of the air exhaust cylinder; the tail gas impurity treatment device is arranged on the coating kettle. The tail gas impurity treatment device has the advantage that when the raw coke reacts in the coating kettle, the produced tail gas is movedto an air exhaust port and sent into the air exhaust cylinder, the attaching substance is formed at the inside wall of the air exhaust cylinder after long-time use, the scrap plate in the air exhaustcylinder is driven by the first motor to rotate, and the attaching substance at the inside wall of the air exhaust cylinder is scraped off by the rotation of the scrap plate, so as to avoid the blockage of the air exhaust cylinder due to accumulation of attaching substance in the air exhaust cylinder, thereby avoiding the damage to the coating kettle due to failure of pressure release in the coating kettle.

Description

technical field [0001] The invention belongs to the technical field of coating kettles, and in particular relates to a tail gas impurity treatment device and a coating kettle. Background technique [0002] During the reaction process of raw coke in the coating kettle, a large amount of tail gas will be produced. The tail gas contains water, tar and volatile components. In the exhaust pipe of the covered kettle, when the exhaust gas is discharged through the exhaust pipe, it needs to pass through a spiral structure exhaust gas stirring device, and the substances in the above-mentioned tail gas and a small amount of material will adhere to the stirring device; after long-term use , the attachment on the stirring device becomes more and more sticky, so that the exhaust pipe is completely blocked, so that the pressure in the coating kettle cannot be released, and the coating kettle is easily damaged. Therefore, it is a technical problem to be solved urgently by those skilled in...
