Cyclone separator for air sampler

Abstract

The invention discloses a cyclone separator for an air sampler, and belongs to the technical field of cyclone separation equipment. The cyclone separator comprises a cone, a spiral pipe is mounted above the cone, a dusty air inlet is formed in the left side of the spiral pipe, a clean air outlet is formed in the right side of the spiral pipe, and a vortex cover is mounted in the cone. A first cyclone separation space is formed in the left side of the vortex cover, a second cyclone separation space is formed in the right side of the first cyclone separation space, a discharging opening is formed in the lower portion of the cone, and an ash hopper is installed below the discharging opening. When the device is used for separating air, graded air separation is adopted so that the separation effect is good, air backflow cannot be caused, backflow of the whole device is avoided, the backflow effect is avoided, separated air is further separated, and when the air sampler is used, the test result is more accurate; and convenience is brought to use of workers.

Description

technical field [0001] The invention relates to the technical field of manhole covers for cyclone separation equipment, in particular to a cyclone separator for an air sampler. Background technique [0002] In the prior art, the cyclone separator is the key equipment for gas-solid separation, and the separation efficiency is the key index. The conventional design is usually about 85%. How to improve the separation efficiency has become the key issue in the design of the cyclone separator. In addition, the minimum Particles are also one of the important indicators. With the development and application of nanomaterials, it is hoped that the separable critical diameter must be ≤1um. At the same time, from the perspective of environmental protection, it is also hoped that the dust content in the exhaust gas must be ≤0.1Kg / m3 to reduce filtration. The burden of bag or water film dust removal. Ensure the national standard of dust emission ≤30mg / m3. This places extremely high req...

AI Technical Summary

Problems solved by technology

[0004] The cyclone separator of the above-mentioned technology has the following disadvantages: 1. When the device separates air, it does not use fractional separation of air, so that the separation effect is poor, and it is easy to cause air backflow, so that the whole device is tested for backflow, and the backflow effect is poor; 2. , The device does not separate the separated air in a finer step, which makes the test results inaccurate when the air sampler is in use, which is inconvenient for the staff to use
