What are the general reasons for the damage of the dust bag

Bag filters can be used with cloth bags. Bag filter is a common filter and dust removal equipment, and its working principle is to capture the dust and impurities in the air through the filtration of the bag to achieve the purpose of purifying the air. When using cloth bags, you need to pay attention to the following:

1.The material of the bag should match the dust and impurities that need to be filtered. Bags of different materials have different filtration effects and application ranges, and it is necessary to choose the appropriate bag according to the actual situation.

2.The installation of the bag should be firm and reliable to avoid loosening or falling off, and at the same time, it should also pay attention to the hygienic conditions during installation to ensure the cleanliness of the bag. 3.

The cloth bag needs to be replaced or cleaned regularly during use to ensure the filtration effect and service life. 4.When using a bag filter, you need to pay attention to safety issues, such as....

The reasons for the damage of the dust bag may be as follows:

Excessive use time: With the growth of use time, the dust bag will gradually wear out and age, resulting in the decline of the strength and durability of the bag, and it is easy to break.

Excessive airflow pressure: When the airflow pressure is too large, the pressure on the dust bag will also increase, which can easily lead to damage and damage to the bag.

Dust particles are too large or too hard: If the dust particles are too large or too hard, it will cause a large impact on the surface of the dust removal bag, resulting in damage to the bag.

Frequent ash cleaning: Frequent ash cleaning will lead to repeated vibration of the dust removal bag, which will reduce the strength of the bag and be prone to damage.

The temperature is too high or too low: The dust bag is prone to aging and deformation in a high or low temperature environment, resulting in the damage of the bag.

Selection of unsuitable bag materials: different working conditions and environments need to use different materials of dust bags, if the selection of inappropriate bag materials, will lead to the decline of the strength and durability of the bag, easy to break.

The above are some of the reasons for the damage of the dust bag, and the specific situation needs to be analyzed according to the working environment, working condition requirements and other factors.

The upper mouth of the dust bag is damaged. Causes: Compressed air is too high; The blowpipe is skewed; deformation of the flower plate and other reasons. It is an installation quality problem. Phenomenon: Blown within 30 to 40 cm of the mouth (from the bottom to the outside).

The body of the dust bag is damaged. Reason: The size of the cloth bag and the skeleton do not match, and the finish of the surface of the skeleton is dusted. Phenomenon: The contact part between the bag body and the skeleton is broken.

The bottom of the lower part of the dust bag is broken. Reason: Because the bottom of the skeleton is too small or the bag is too long, the ash cleaning operation is too large, resulting in the inner grinding of the bottom of the bag; Or the dust accumulation is too high, forming a vortex to wear the cloth bag. Phenomenon: The bottom of the bag is worn.

Open flame sparks. Reason: There are sparks in the smoke, which causes small holes to burn. Phenomenon: There are dotted small cylinders on the dust bag.

High temperature flue gas. Reason: The temperature of the bag exceeds the tolerance range of the bag, and the bag is damaged due to excessive turbidity and heat shrinkage. Phenomenon: Shrink violently or harden severely, twist it with your hands on the rotten part of the cloth bag, if it is broken into powder.

There are many reasons for the damage of the dust bag, and there is a corrosive gas in the dust bag burned by high temperature flue gas. Damage to dust bags caused by corrosion. The filtration air speed is too high, which causes damage to the cloth bag. Excessive humidity causes hydrolysis of the cloth bag.

The reasons for the damage of the dust bag are generally as follows. Damage caused by corrosion, damage caused by high temperatures, damage caused by abrasion.

Selection of bags: The material and specifications of the bags need to be selected according to the nature of the materials to be processed, the size of the granular materials, temperature and humidity and other factors, otherwise it will affect the effect of dust removal and grinding.

Bag cleaning: Clean the filter bag regularly to avoid deformation or clogging of the filter bag. It should be noted that when cleaning, do not use hard objects to collide with the filter bag, so as not to damage the empty bucket and damage the filter bag.

Injection system: The injection system also needs to be inspected and maintained regularly to ensure that it is working properly. For example, check whether the nozzle is clogged or worn, whether the injection force is appropriate, etc.

Bottom bucket cleaning: Excessive dust accumulation in the bottom bucket will affect the work efficiency of the bag filter, and it needs to be cleaned regularly and collected and processed.

Air tightness: In order to ensure the dust removal effect, the air tightness of the bag filter must be good, and the parts such as pipeline joints must be sealed reliably.

Operator training: Operators should be professionally trained to master the operation steps and skills, improve operational efficiency and safety, and reduce the risk of damaging equipment.

Bag replacement: Bags have a limited lifespan and need to be replaced regularly. When replacing, it is necessary to pay attention to ensure that the material and specifications of the new and old filter bags are consistent, so as not to affect the dust removal effect.

The above problems are all details that need to be paid attention to when operating the bag filter, and they need to be taken seriously and solved.

First, there is a leak between the air inlet duct and the partition. The reason for this problem is mainly due to the long-term grinding of the partition between the air inlet duct and the individual chambers, which makes the partition thinner.

At the same time, the welding part of the bag filter is often worn through and worn through, so that part of the dust gas can directly enter the dust bag from the leakage point without being filtered by the bag, resulting in the dust particles being directly discharged into the atmosphere, and ultimately reducing the dust removal efficiency of the bag filter.

The second is the leakage between the air inlet duct and the air outlet duct. In fact, the front and rear air ducts of the bag filter flow in the dusty hidden gas and clean gas respectively, and once the partition between the air duct and the air duct is subjected to different degrees of abrasion, the strength of the steel plate will become very low.

At the same time, due to the vibration of the air flow in the front and rear air ducts, the steel plate between the front and rear air ducts is often torn, which undoubtedly increases the wear degree of the bag dust collector, and also reduces its dust removal efficiency to a certain extent.

Hello landlord.

Baghouses generally don't have problems. There are 2-3 types of problems when there is a problem. It is also very good to solve the first: damage to the bag in the bag filter. This is a consumable. A new one will do.

Second: the pipeline is damaged. Just add it directly with the original material. Use self-tapping nails to resist.

Third: it is the problem of fans. If you have a small problem, you will go to the repair, and if you have a big problem, you will go out to find the company that will install the dust box for you. Ask them to come and change the fan or just replace it with a new one.

A dust collection hood is set up in each ash place, and the dust-containing gas is transported to the dust removal device through the pipeline gas path, in which the dust is collected in the dust removal device after the gas-solid separation is carried out, and the clean gas is introduced into the main pipe or directly discharged into the whole set of equipment into the atmosphere, that is, the dust removal system, and the dust collector is an important part of the system. From the perspective of ventilation and dust removal, dust is all solid small particles that can float in the air for a long time, and is a dispersion system, called aerosol, in which air is the dispersed medium and solid particles are the dispersed phase. A dust collector is a device that separates these small solid particles from aerosols.

The main reasons for the damage of the dust collector bag are generally as follows:

1. Filter wind speed.

The filter air velocity of the bag filter is too high, which is the main reason for the damage of the bag of the dust collector. In recent years, some units blindly reduce equipment costs, increase profits, in the design of the bag filter, the filtration speed is increased, the user has no obvious response in a short time, but greatly shortens the service life of the dust collector bag. Instead of saving money, this brings a huge financial burden to the customer and wastes time.

2. Dust medium.

The selection of the bag cloth of the dust collector is determined by the dust nature of the dust, and it is necessary to consider whether the dust contains acid, alkali or corrosive substances. According to the nature of the dust, the filter material suitable for it is selected, so that the filter bag can absorb the dust normally, and its service life is not affected.

3. Operating temperature.

Correctly selecting the dust collector bag suitable for the corresponding dust temperature is the key to the filter bag. If the temperature is too high, the selected dust collector bag will exceed the normal use temperature, and the filter bag will shorten the service life at least, and the serious one will burn out in a short time. Therefore, when selecting filter bags, it is necessary to measure and calculate the inlet temperature of the dust collector, and select the corresponding dust collector bag.

The advantages and disadvantages of the dust removal effect of the general dust collector bag are related to a variety of factors, but it mainly depends on the bag protective sleeve, which is a cloth or felt woven from synthetic fibers, natural fibers or glass fibers. The protective sleeve can be made of cotton wool fiber, glass fiber or various chemical fibers through spinning (or needle-punched) into filter material, and then sewn into a vertically hung filter bag, and different filter materials should be selected for different occasions. Sew the cloth or felt into a bead-type dust collector bag as needed.

There are many reasons why the junior high school does not have damage, and the first one may be caused by too high wind speed. No damage, that is, without a dust collector, the small fan is too large. The second is that the high temperature burns out the dust bag or the fabric produces high-temperature irreparable damage.

The third is due to corrosiveness, the dust bag is damaged. The fourth is caused by the damage of the dust bag by foreign bodies, and the dust bag is damaged.

The filter bag is the heart of the dust collector and is very important for the service and maintenance of the filter bag. The main reasons that affect the service life of the filter bag are as follows:

1. The filter bag is blocked, and the filter bag is blocked, which will cause the filter bag to wear, perforate and fall off. During the service and maintenance process, it can be found that the blockage can be dealt with by temporarily intensifying the cleaning method, or the bag can be replaced directly.

2. If the filter bag is wet, you need to check whether there is water leakage, keep the bag dry, and try to clean the ash repeatedly.

3. The cleaning cycle is too short and needs to be lengthened.

4. The ash cleaning cycle is too long and needs to be shortened.

5. The tension of the filter bag is insufficient, and the adjustment is strengthened.

6. The filter bag is too loose and increases the tensile force.

7. The filter bag is poorly installed and adjusted and fixed.

8. The filter bag is aging, hardening and heating, burning, leaking dust, and the filtration rate is too high, which will cause the aging of the cloth bag.

The shape, installation and structure of the filter bag are the main reasons for the damage, in addition, the temperature is too high, and the reaction of acid and alkali and other compounds in the flue gas will also lead to the aging and damage of the bag.
