Brief introduction of bag dust removal equipment, introduction of bag dust removal equipment 的应用已有一百多年的历史. 其最大优点是除尘效率高(高达99. 99 %以上)，排放浓度可达1以下。 The application of bag dust removal equipment has a history of more than 100 years. The biggest advantage is that the dust removal efficiency is high (up to 99. 99%), and the emission concentration can reach below 1. .... 0 mg / m3, the classification efficiency is also very high, it is 2.5 or less particles. Μm also has a very good capture efficiency, so it is widely used. However, after many years of operation, the bag filter has also exposed some problems, such as easy damage to the filter bag, dew condensation, large running resistance, failure in cleaning, and poor ash discharge. There are many factors that cause problems in the operation of bag dust collectors. In addition to their own factors, improper operation management is also an important cause of problems in the operation of bag dust collectors.
1 filter bag problem
1.1 Damage of filter bag by high temperature smoke
(1) High temperature combustion
(2) Mars burns through
(3) High temperature shrinkage
(4) Ash bucket accumulative heat storage combustion filter bag
1.2 Filter bag corrosion
(1) acid-base corrosion
1. 3 mechanical damage
1. 4 design issues
1. 5 quality issues
1.5.1 Production quality
(1) Filter bag product quality
(2) Quality of bone production
(3) Installation quality does not meet requirements
Due to the characteristics of high viscosity, high temperature, and easy condensation of electric furnace dust, it is easy to cause problems during dust removal. The main reasons are as follows: (1) high humidity, dust adhesion and even stickiness; (2) lower bridge of ash bucket; The ash discharge valve's ash discharge capacity is too small; (4) The ash discharge port leaks air.
1: The pulse bag dust collector is widely used and has become the mainstream of high-efficiency dust removal equipment. Faults occur during use. As long as the analysis is accurate and the processing is timely, the stable operation of the pulse bag dust collector can be guaranteed, the running resistance can be effectively reduced, the service life of the filter bag can be extended, and the dust cleaning gas can be reduced, thereby reducing the operating cost and fully utilizing the pulse Advantages of bag type dust collector, realize cost-effective dust removal.
2: The bag filter cannot be in the design state for a long time. When it deviates from the design state, the bag filter will inevitably be damaged. However, the use cost of the filter bag is the majority of the maintenance cost of the bag filter, accounting for more than 70% of the maintenance cost.
3: There are many parts that are prone to failure, such as filter bags, dust cleaning devices, ash buckets, etc. Damage to the filter bag will cause the dust collector to fail. Only by properly selecting the type and working parameters (such as filtration speed), specifications, and ash removal methods of the filter material, and equipped with reliable control and protection devices, can the purpose of reliable, low resistance, small maintenance and good dust removal effect be achieved.
