Overview of dust collectors in chemical plants:

The dust collector in the chemical plant has achieved direct collection of dust in China's chemical industry, improving the situation of wet dust collection. This equipment is suitable for direct collection of various dust generated by process equipment in the chemical industry production.

Technical characteristics of dust collectors in chemical plants:

The advantages of comprehensive chamber blowback and pulse jet dust removal in chemical plant dust collectors overcome the shortcomings of insufficient chamber blowback intensity and simultaneous jet filtration, enhance adaptability, improve dust collection efficiency, and increase the service life of filter bags. According to the different corrosiveness of dust in the chemical industry, different anti-corrosion measures are adopted for steel structural components and elements to prevent the entire dust collector from being corroded.

Through examples, it is shown that in the chemical industry, this dust collector is used to collect dust generated in the production of dust recovery and treatment process equipment. The inlet concentration can reach 500g/Nm3, and the outlet concentration is only 50mg/Nm3. The collected dust is directly bagged or returned to the process as finished materials. Chemical dust collectors not only simplify the process of recycling and reuse, but also reduce equipment investment, reduce labor intensity for workers, and lower the cost of dust recovery in chemical plants.

Precautions for the operation of dust collectors in chemical plants

Among various dust removal devices, bag filters in chemical plants have superior dust removal performance, with processing air volumes ranging from hundreds to millions of cubic meters per hour. Moreover, maintenance and management are relatively easy, so various types of bag filters in chemical plants are widely used. However, whether it is the design or operation of bag filters, practical experience accounts for a large proportion compared to theory. A large amount of investigation and statistical materials indicate that if operational management is not taken seriously in daily life, even excellent equipment cannot fully exert its performance, and may even experience various malfunctions, making it difficult to operate normally. If the maintenance and operation personnel are experienced and responsible, even if there are some shortcomings in the design and manufacturing of the equipment, the dust removal equipment can operate for a long time under normal operating and maintenance conditions, and the operating costs are also relatively low. From this, it can be seen that the maintenance and management of bag filters is not an optional issue, but a very important and important issue that must be taken seriously.

Due to the domestic production of chemical plantsBag filterThere are many manufacturers with significant differences in product quality, so it is important to be familiar with and master the product manuals provided by the manufacturers during operation and maintenance. Pay attention to the specific requirements for operation and maintenance management in the manuals, and archive and store them for future reference. In order to ensure the long-term stable operation of the bag filter in the chemical plant system, the following precautions must be taken when using the filter.

a. Before purchasing a bag filter for a chemical plant, it is necessary to thoroughly study the technical information related to the dust collector based on the production process conditions, consider whether it can meet strict environmental requirements and approximately 5 years of operating costs, conduct technical and economic comparisons based on comprehensive factors, and determine the specifications and performance of the equipment to select the best and eliminate the worst.

b. Strictly follow the requirements of the drawings and technical specifications provided by the manufacturer for operation, and do not change the operating conditions arbitrarily without sufficient basis and reasons to prevent faults caused by changes in operating conditions.

c. To understand and master the technical requirements and operating points of bag filters and the various parts that make up the dust removal system, pay attention to the rationality of matching each part, and try to avoid situations where one part is too big or too small.

d. Always pay attention to the working condition of the dust removal bag. If any abnormalities are found, analyze the cause and handle them in a timely manner.

e. Regularly pay attention to and record the temperature, humidity, and pressure of the gas entering the bag filter, so that the filter operates under the specified parameters, and avoid operating below the dew point temperature of the gas.
