Problems solved by technology

Because the diameter of gas pipelines in iron and steel enterprises is often very large, many of which exceed 2000mm, the price of electric butterfly valves and electric blind valves on large-diameter gas pipelines is very high. The price of a single valve is hundreds of thousands or even hundreds of thousands of yuan. is a big investment

Abstract

The invention provides a full-automatic intelligent cut-off water-sealed valve system and method for hot dirty gas. The system comprises a water-sealed valve body, a radar liquid level meter, a water feeding pipe, a water return pipe, a water tank, a water pump and an electromagnetic valve. The water-sealed valve body is of a box type structure, and a gas inlet, a gas outlet and a gas diffusion opening are formed in the top of the water-sealed valve body. A high-position water outlet, a middle-position water outlet and a low-position water outlet are sequentially formed in the side wall of the box body from top to bottom; the water inlet is formed in the same horizontal position as the high-position water outlet and is connected with a water pump outlet through a water feeding pipe; and the electromagnetic valve is arranged on a pipeline of the middle-position water outlet. The radar liquid level meter is fixed to the upper end in the water-sealed valve body box body, and the radar liquid level meter, the water pump and the electromagnetic valve are all connected with the PLC. Through the electromagnetic valve design of the high water outlet, the middle water outlet, the low water outlet and the middle water outlet, the water-sealed valve can be automatically in the normal working state and the cut-off state, and the water-sealed valve can be applied to a hot dirty gas pipeline and is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of water seal valves, in particular to a system and method for an automatic intelligent cut-off water seal valve for hot dirty gas. Background technique [0002] The gas water seal valve is widely used in industrial enterprises that generate and use gas. The principle of the gas water seal valve is to use the static pressure of water to prevent the flow of gas. There are three functions of the gas water seal: ① It is used for gas pipeline discharge pipes The condensed water accumulated in the tank; ② for gas pipeline cut off; ③ for gas backstop. The gas water seal has the advantages of simple structure, low investment, safety and reliability. [0003] Butterfly valve, blind valve or blind plate can be used to cut off the gas pipeline. Electric butterfly valve and electric blind valve are required for gas with a nominal diameter larger than 600mm. Because the diameter of gas pipelines in iron and steel ente...
