Has the characteristics of simple structure and suitability for mass production.
Description
Technical Field
A hollow fiber membrane module for treating high dust gas.
Background
Flue gas generated during combustion of petrochemical fuel contains high-concentration dust, and the dust is intercepted by using a filter material, which is a main purification method. However, the filter material is always a weak link for a long time, and the conventional bag-type dust remover can only reach the milligram level. Gushaohua proposes a hollow fiber membrane high-dust gas purification device, (patent application No. 2018102481428), and experiments prove that the device can treat high dust in flue gas to a microgram level at one time under the condition of not increasing wind resistance, the filtering efficiency is improved by 3 orders of magnitude compared with that of the traditional bag-type dust remover, and the dust concentration of the treated gas can be lower than the atmospheric background value. Industrial devices manufactured according to this principle are currently undergoing on-line pilot plant tests in smelters and cement plants, with preliminary results being satisfactory.
A hollow fiber membrane high-dust gas purification device (patent application No. 2018102481428) relates to a membrane component with a back-blowing function, in order to resist high temperature and obtain better back-blowing effect under the condition of saving compressed air, a mode that membrane wires are fixed on an air nozzle and the air nozzle is accurately aligned with the air nozzle is adopted, when airflow in inner holes of the membrane wires is upward, a filtering task is executed, directional flow high-pressure back-blowing pulse airflow formed by the air nozzle can easily overcome the filtering airflow, reverse-phase pulse high-pressure airflow from top to bottom is formed in the inner holes of the membrane wires, and dust deposited on the outer surfaces of the membrane wires is cleaned. The successful premise of the structure is that the air nozzle and the air nozzle are accurately aligned and slightly deviated, and directional air flow cannot accurately enter the inner hole of the membrane wire at a fixed point. For this reason, the design of upper flower plate and lower flower plate is adopted in this structure, and the method of gluing or clamping membrane silk and tuyere is adopted, and in order to bear high temperature, these parts adopt metal material. Although the design is good in quality, the mass production is difficult, the workload of metal processing is large, and particularly, the fixing of the air nozzle and the membrane wire and the difficulty of automatic assembly are large. For example, in a power plant, the exhaust gas volume is about 100 ten thousand meters/h, 20 ten thousand membrane filaments are needed, each membrane filament needs a pair of air nozzles and air nozzles, and the processing amount is very large.
