, 工业粉尘处理已成为很多企业关注的问题 , 那么企业在选择工业除尘器来治理工业粉尘应注意影响工业除尘器的收集效果有那些 , 现在我们一起来了解一下. Now, with the rapid development of industry, the treatment of industrial dust has become a concern for many enterprises.Then when companies choose industrial dust collectors to control industrial dust, they should pay attention to those that affect the collection effect of industrial dust collectors.Now let us take a look.
A. Filter bag material
The selection and application of bag filter materials is the core technology of bag dust collectors and plays a decisive role in the performance of the dust collector. Due to the environment of each dust collection point, the nature, temperature, and technical requirements of the treated dust are different. According to different conditions, different filter materials should be selected and corresponding technical protection measures should be taken. The requirements for filter bag materials include the following technical properties: filter bag materials are suitable for different temperatures, good peelability, easy dust removal, good air permeability, low resistance, high filtration efficiency, high strength, can withstand high strength dust removal, use Long life and reasonable price.
B. Filtered wind speed
Filtering wind speed is an important parameter that determines the performance of the dust collector, and also an important parameter to measure the advanced nature of the bag dust collector. The filtering wind speed is closely related to the dust concentration, dust particle size, application occasions, viscosity, gas temperature, moisture content and dust removal method of dust-containing gas. When the particle size of the dust is fine, the temperature and humidity are high, the concentration is large, and the viscosity is large, the filtering wind speed should be lower, otherwise a higher value can be selected. Excessive filtering wind speed will increase the load of the filter bag, increase the filtration resistance, and lead to short service life and low efficiency of the filter bag.
C. Air leakage
<3 ％。 Air leakage directly affects the dust collection effect and life of the dust collector, and the required air leakage rate is <3 %. Bag-type dust collectors are generally operated under negative pressure. If there is air leakage, it is easy to form a short circuit short circuit. The dust collection system is not handling enough air volume to form positive pressure dust. Leakage of the air will also reduce the temperature of the system, and it will easily form moisture, which will increase the dust collection resistance and reduce the dust collection effect.
Insulation is also a must for bag dust collectors. Insulation is to keep the gas and to avoid the moisture bag. Most filter bags appear smeared and clogged, which is caused by low dust temperature and high humidity.
E. Dust removal interval
The dust removal time interval is too long, and the dust attached to the filter bag cannot be eliminated in time, which causes the system resistance to increase. 4s 左右 ( 可根据实际生产情况调整 ) 喷吹，喷吹时间为 0 ． Generally, the interval time is about 4s ( can be adjusted according to the actual production situation ) , and the blowing time is 0 . ～ 0 ． 2s ～ 0 ． ，室与室的时间间隔为 30s 左右。 3s , the time interval between room and room is about 30s .
F. Ash removal
The ash bucket cone does not discharge ash smoothly, too much ash is accumulated in the ash bucket, and the air inlet is blocked, resulting in poor ventilation.
The wind on the top of the dust collector and the surrounding walls is severely leaky. It will enter the water when it rains, causing sacks, or wet materials to form clumps and block the ash outlet of the cone.
