Matters needing attention for operation of chemical dust collector:


Among all kinds of dedusting devices, the dedusting performance of chemical dust remover is superior, handling air volume from hundreds of cubic meters to millions of cubic meters per hour. And maintenance management is relatively easy, so a variety of chemical dust remover is widely used.However, both the design and operation of the bag filter, practical experience and theoretical experience account for a large proportion. A large number of investigation and statistical materials show that if the operation management is not paid attention to at ordinary times, even excellent equipment cannot give full play to its performance, and even various failures may occur, making it difficult to operate normally. If the maintenance and operation personnel are experienced and responsible, the dusting equipment can be operated for a long time under normal operation and maintenance conditions even if there are some defects in the design and manufacture of the equipment, and the operation cost is relatively low. It can be seen that the maintenance and management of bag filter is by no means an optional problem, but a very important and important one.


As there are many manufacturers of dust remover in chemical plants in China, the quality of products varies greatly. Therefore, it is necessary to be familiar with and master the product specifications provided by the manufacturer during operation and maintenance.


In order to ensure the stable operation of chemical dust collector in its system, the following points should be noted:

1. Before purchasing deduster in chemical plant, according to the production process conditions, fully study the technical data of the deduster, consider whether it can meet the strict environmental protection requirements and the running cost of about 5 years, and make technical and economic comparison according to the comprehensive factors, so as to determine the specification and performance of the equipment and select the superior and inferior.


2. Operate in strict accordance with the drawings and technical specifications provided by the manufacturer, and do not change the operating conditions without sufficient basis and reasons, so as to prevent faults caused by changes in operating conditions.


3. Understand and master the technical requirements and operating points of bag-type dust collector and all parts of the dust removal system, pay attention to the rationality of matching of all parts, and try to avoid such situation as large or small as possible.


4. Pay attention to the working situation of dusting cloth bags, analyze the causes and deal with them in time.


5. Always pay attention to and record the gas temperature, humidity and pressure entering the bag filter, so that the dust collector can operate under the specified parameters. Do not operate below the temperature of the air dew point.
