Description

Technical Field

[0001] The present invention belongs to the field of pollution control, and particularly relates to an incineration device for waste gas and waste liquid. Background Art

[0002] To meet the domestic market demand for mid - to - high - end products and products relying on imports, the state encourages and supports the construction of chemical new material and high - end fine chemical product plants. During the operation of these chemical plants, a large amount of waste gas and waste liquid are generated, which have no recycling value and cannot be directly discharged, and need to be treated to meet the standards before discharge. For example, steam cracking, ethylene plant, EOEG plant, ethylbenzene - styrene plant, high - density polyethylene plant (HDPE), full - density polyethylene plant (FDPE), polypropylene plant, ABS plant, butadiene plant, C4 combined plant, pyrolysis gasoline hydrogenation combined plant, p - xylene plant, polyether polyol, propylene oxide plant, hydrogen peroxide plant, coal chemical plant, etc. For a chemical plant, these plants are often built together, and the waste gas and waste liquid generated need to be collected and treated uniformly. The characteristics of this waste gas and waste liquid treatment device are: numerous streams, complex components, large fluctuations in flow rate and concentration, and high treatment difficulty.

[0003] Currently, for the treatment of waste gas and waste liquid with complex components from multiple plants, the preferred method is incineration. Through high - temperature thermal oxidation, the waste gas and waste liquid from multiple plants in the whole plant are centrally treated. For waste gas and waste liquid with numerous streams, complex compositions, and different physical properties, how to safely receive and transport the waste gas and waste liquid, and how to reasonably organize combustion to avoid defects such as poor combustion caused by reactions between waste gas and waste liquid are one of the problems urgently needed to be solved in this field. Summary of the Invention

[0017] (III) Beneficial effects

[0019] In the present invention, the first partition plate and the conical part form a top combustion space, the first partition plate and the second partition plate form a middle combustion space, and the second partition plate and the bottom of the cylindrical part form a bottom combustion space. The top combustion space, the middle combustion space, and the bottom combustion space are all enclosed spaces. Therefore, the present invention can treat waste gas and waste liquid with different characteristics in three enclosed spaces at the same time, avoiding the mutual influence of waste gas and waste liquid during the incineration process.

[0020] The partition sliding assembly of the present invention drives the first partition plate and the second partition plate to move up and down through the magnetic attraction connection between the second electromagnet and the first electromagnet. Therefore, the top combustion space, the middle combustion space, and the bottom combustion space in the present invention can actively combine with each other according to the characteristics of the waste liquid to form a combustion space or jointly form an integral combustion space, thereby improving the incineration efficiency and reducing the fuel consumption.

[0021] Before the first partition plate and the second partition plate of the present invention move up and down, the telescopic motor controls the high-calorific value waste gas gun, the second burner, and the third burner to move outward from the inside of the incineration inner tank. The first partition plate and the second partition plate can remove the dirt on the inner wall of the incineration inner tank during the up and down movement. Description of the drawings
