Treatment system for dust mixed gas

Abstract

The invention provides a treatment system for dust mixed gas. The dust treatment system for dust mixed gas comprises a first filtering system (1), a second filtering system (3) and a control part. The first filtering system 1 comprises a first filtering pipeline 1a, a first filtering device 2a, a first forward air inlet control valve A1 and a first forward air outlet control valve A2, wherein the first filtering device 2a, the first forward air inlet control valve A1 and the first forward air outlet control valve A2 are arranged in the first filtering pipeline 1a. The second filtering system 3 comprises a second filtering pipeline 1b, a second filtering device 2b, a second forward air inlet control valve B1 and a second forward air outlet control valve B2, wherein the second filtering device 2b, the second forward air inlet control valve B1 and the second forward air outlet control valve B2 are arranged in the second filtering pipeline 1b. Two ends of the first filtering pipeline 1a and the second filtering pipeline 1b are respectively used as an inlet and an outlet of the dust mixed gas. A compressed air inlet pipe, a compressed air outlet pipe and a control valve for controlling compressed air are respectively formed on branches at two ends of the first filtering device 2a and the second filtering device 2b. The control valves are controlled by the control part, so the first filtering device 2a and the second filtering device 2b alternately filter the dust mixed gas.

Description

technical field [0001] The invention relates to a dust mixed gas processing system, in particular to the operation of the processing system. Background technique [0002] Lithium resources mainly exist in salt lakes, spodumene and lepidolite rock deposits. In salt lake brine, the ratio of magnesium to lithium is about 500:1. Under the constraints of such ultra-high magnesium-lithium ratio factors, it is difficult to extract lithium resources by commonly used electrodialysis, extraction, calcination, and precipitation methods. Lithium in salt lake brine is usually extracted by lithium adsorbent and adsorption lithium extraction technology Resources, and the production of high-quality lithium adsorbent is the key element to ensure the production of lithium products, so the normal production and quality control of lithium adsorbent is very important. [0003] The main production process of lithium adsorbent is as follows: firstly, several kinds of raw materials are dissolved ...

AI Technical Summary

Problems solved by technology

[0005] The powdery material (dust) mixed in the volatilized organic gas in this process enters the recovery device and adheres to the heat exchange fins, which not only reduces the heat exchange efficiency, but also blocks the heat exchange channel as the amount of dust increases, causing the system to shut down and seriously affecting The normal production of adsorbents is hindered, resulting in economic losses

[0006] After the heat exchange channel is blocked, it needs to be stopped and manually cleaned before starting production. However, the cleaned system will be blocked by dust after a period of operation. After the blockage, stop and clean it, and then start the car after cleaning

[0007] This reciprocating start-stop production method not only reduces production efficiency and equipment service life, but also increases production costs and equipment failure rates, which seriously affects normal production.

[0008] As a solution, although a dust filter device can be installed at the front end of the H liquid recovery device to filter the mixed gas entering the H liquid recovery device to prevent the pipeline from being blocked by dust, the filter device needs to be cleaned regularly or the filter screen needs to be replaced. Fundamentally solve the problem of starting and stopping of equipment in the production process

[0009] The present invention is based on the problems of the above-mentioned prior art, and the first purpose is to solve the problem of discontinuous operation of the dust filter device
