Problems solved by technology

Relying on the self-operated decompression valve or spring-type decompression mechanical device in the prior art is difficult to achieve accurate pressure adjustment when the height difference is small, and for the adjustment device installed in the pool, it is not easy to judge whether the adjustment effect is good or bad

Embodiment Construction

[0012] exist figure 1 In the figure, the air pressure control device (2) is outlined with a dotted line as a whole, and the air source (1) is connected to the air inlet (3) of the air pressure control device (2) through the air intake pipe (11), and the outlet of the air pressure control device The gas port (6) is connected to the gas distributor (8) through the gas outlet pipe (10), and the gas distributor is installed at a certain depth in the water pool (9). The shell (7) of the air pressure control device is a sealed container, and there is a certain height of water in the shell as a water seal. The air pressure control tube (4) connected to the air inlet is inserted below the liquid level of the water seal (5) in the airtight container. There is a liquid level control port (12) at the surface height, which communicates with the gas outlet (6) protruding from the shell of the air pressure control device, and the gas outlet is connected to the gas distributor (8) in the poo...

Abstract

The invention relates to a gas pressure control device, which has a simple structure and automatically forms a water seal when necessary, and can adapt to the needs of gas supply pressure adjustment of different water depths.

Description

technical field [0001] The invention relates to the working principle of an underwater air supply air pressure control device, in particular to the air supply pressure control of different water level heights of pools in the field of water treatment. Background technique [0002] Biochemical processes are often used in the sewage or wastewater treatment process, and air or oxygen needs to be filled into the water, which is divided into blast aeration and mechanical aeration. Generally, blast aeration can obtain different bubble sizes according to different aeration methods, and the size of the bubbles affects the transfer efficiency of oxygen. Due to the small specific surface area and fast rising speed of medium air bubbles, the transfer efficiency of oxygen is relatively low, and the energy consumption of aeration equipment is relatively high, so it is basically only used in a few occasions. Micro-bubbles mostly use porous materials as an aeration device, which is called ...
