Description

Technical Field

[0001] This utility model relates to the field of tank design, specifically to a fully enclosed horizontal tank. Background Technology

[0002] The coking plant's gas purification area is responsible for gas quality management and chemical product recovery. During the production process, various underground tanks are needed for solution storage or transfer. Due to defects in the initial design and long-term use of most underground tanks, there are cases of liquid leakage and gas release into the air, which brings great environmental problems to the surrounding atmosphere and soil.

[0003] With increasingly stringent environmental protection requirements, the control over unorganized emissions of gas from storage tanks has been further strengthened. Conventional methods such as replacing underground tanks are used to solve the problem. Although conventional storage tanks can solve the problem of gas escape, they are difficult to meet the needs of coking plants for multi-functional chemical production tanks. Moreover, conventional underground tanks are buried low, making it difficult to detect tank leaks. Utility Model Content

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: This utility model is a fully enclosed horizontal tank, including saddle supports, of which multiple sets are provided. A cylindrical body is installed on each of the multiple sets of saddle supports. Elliptical end caps are welded to both sides of the cylindrical body. External pipes are installed through two sets of elliptical end caps. The external pipes are used for liquid inlet and outlet. Two sets of side liquid inlet pipes are installed through the cylindrical body. Two sets of top liquid inlet pipes are installed through the cylindrical body. A manhole is connected to the cylindrical body for equipment inspection. A VOCs interface is connected to the cylindrical body for VOCs gas recovery. A breather valve is connected to the cylindrical body for pressure balance adjustment inside the cylindrical body.

[0006] Furthermore, a steam pipe is connected to the cylinder, and a steam generator is connected to the external steam pipe.

[0007] Furthermore, two sets of mounting bases are installed on the cylinder body, and the mounting bases are used to install the submersible pump.

[0008] Furthermore, a drain pipe is connected to the bottom of the cylinder.

[0009] Furthermore, a conventional level gauge interface pipe is connected and installed on the cylinder body, and the conventional level gauge interface pipe is used to install a conventional level gauge.

[0010] Furthermore, an electronic level gauge is connected and installed on the cylinder.
