Safe diffusing device for gas transmission and using method

Abstract

The invention belongs to the technical field of gas power generation sets, and provides a safe diffusing device for gas transmission and a using method. The safe diffusing device for gas transmission is provided with a hollow cylinder (3) with the two ends closed, an air inlet pipe (4) is arranged in the hollow cylinder (3), and the diameter of the air inlet pipe (4) is smaller than that of the hollow cylinder (3); the air inlet pipe (4) is provided with a straight pipe section, and a gap is formed between an air outlet of the lower end of the straight pipe section and the bottom face of the hollow cylinder; a bent pipe section bent toward one side is arranged at the upper end of the straight pipe section, an outlet of the bent pipe section is located at the upper end of one side wall face of the hollow cylinder (3), and water for carrying out water seal on gas exists in the gap between the air inlet pipe (4) and the hollow cylinder (3); a water level control valve is installed on one side wall face of the hollow cylinder (3), and a diffusing opening (5) is formed in the upper end face of the hollow cylinder (3). Constant pressure diffusion at multiple pressure levels is achieved to meet different process requirements, and the function of pressure stabilization and overpressure diffusion is achieved.

Description

[0001] Technology area [0002] The invention relates to a safety release device for gas transportation and a use method in the technical field of gas generating sets. Background technique [0003] In the application of gas power generation, if the gas pressure cannot be stabilized in time when the gas delivery pressure changes greatly or the working conditions of the engine itself change, it will lead to unstable operation of the gas engine, which will have a great impact on the air-fuel ratio control and performance of the gas engine; In particular, sudden changes in gas pressure can easily lead to rough operation of the gas engine and large-scale fluctuations in power, which will affect the main moving parts of the gas engine and shorten the service life of the gas engine; in severe cases, knocking will occur, resulting in cylinder scuffing, Piston-rod assembly breaks, causing serious failure or accident.

[0003] In the application of gas power generation, if the gas pressure cannot be stabilized in time when the gas delivery pressure changes greatly or the working conditions of the engine itself change, it will lead to unstable operation of the gas engine, which will have a great impact on the air-fuel ratio control and performance of the gas engine; In particular, sudden changes in gas pressure can easily lead to rough operation of the gas engine and large-scale fluctuations in power, which will affect the main moving parts of the gas engine and shorten the service life of the gas engine; in severe cases, knocking will occur, resulting in cylinder scuffing, The piston connecting rod assembly is broken, causing serious failure or accident

[0004] The wet relief valve involved in the existing patents (application numbers: 200620161497.6 and 201120435116.X) has the following characteristics: (1) the valve body is a cross channel or adopts a double barrel structure, and the structure is complex; (2) it passes through the industrial computer and the liquid Level transmitter or liquid level control by adjusting the height of the water pressure difference tank, the height of the isolation plate and the height of the water level in the water pressure difference tank, the operation is complicated and the cost is high; (3) No cleaning port design, cleaning is troublesome , which is not conducive to maintenance; (4) It is impossible to intelligently control the water temperature in the device
