Scale type spiral flow gas concentration separator

Abstract

The invention discloses a scale-type spiral flow gas concentration separator, which comprises an inner cylinder (1), an outer cylinder (2) and a spiral panel (3), the spiral panel (3) and the inner cylinder (1), The outer cylindrical body (2) constitutes the spiral flow channel (4); the spiral panel (3) is composed of the short plate of the spiral channel (5), and at the joint of the short plate of the spiral channel (5), the short plate of the spiral channel (5) There is a gap between them; on the one hand, the inertial force generated by the fluid in the spiral flow process is used to separate the gases or solids with different densities; on the other hand, the spiral flow channel (4) and the short plate of the spiral channel (5) are used The suction and blowing phenomenon formed by the gap makes the air flow always in a laminar flow state. The invention has a simple structure and low requirements on the place of use. It can separate and concentrate mixed gases with different densities, especially for the concentration and centrifugal separation of binary mixed gases with large density differences. The gas processing capacity is large during use. Energy consumption is very low.

Description

technical field [0001] The invention relates to a gas separator, in particular to a scale-type spiral flow gas concentration separator, which belongs to the technical field of gas separation devices. Background technique [0002] The separation of mixed gases is generally carried out by physical or chemical methods. Generally, physical methods have higher requirements on temperature, and the temperature needs to be lowered to minus 200°C, which requires higher equipment and site requirements; chemical methods for separating mixed gases require the use of chemical agents, which increases the cost of gas separation. It also has certain requirements for the venue. [0003] Based on the above, it can be seen that for chemical or physical methods, these two hair methods are not suitable on certain occasions. For example, in coal mine production enterprises, it is impossible to install large-scale equipment in underground mines for cooling and other operations. But mines often ...

Problems solved by technology

However, mines often contain a mixture of methane and air. On the one hand, the concentration of methane is too high, which is extremely dangerous for mines; on the other hand, if the air mixed with methane is discharged arbitrarily, limited resources will be wasted.
