Product Details

Anti condensation anti blowing flat bag dust collector is a bag dust collector used to separate dispersed particles from gas. It contains a shell with upper and lower flower plates fixed inside to form an inlet chamber, a dust removal chamber, and a cleaning chamber. The three chambers are equipped with inlet pipes, outlet pipes, and cleaning doors on the shell walls. The anti condensation and anti blowing flat bag dust collector has a set of filter bags fixed on the two flower plates in the dust removal chamber. Its characteristic is that the anti condensation and anti blowing flat bag dust collector has a vibrating grid connected by steel wires suspended from the flower plates, and all filter bags are threaded through its mesh holes. The anti condensation and anti blowing flat bag dust collector has the characteristics of anti condensation and preventing filter bag overheating, so it works reliably, has high dust removal efficiency, long service life, and low manufacturing cost.

Dust cleaning mechanism of anti condensation and anti blowing flat bag dust collector

（1） Anti condensation anti blowing flat bag dust collector three-way directional valve. The three-way directional valve has three inlet and outlet ports. During normal dust removal and filtration in the filter bag chamber of the dust collector, the gas flows from the lower port to the exhaust port, and the blowback port is closed. When blowing back to clean the dust, the back blowing air outlet is opened, the exhaust outlet of the anti condensation back blowing flat bag dust collector is closed, and the back blowing airflow blows back to clean the dust in the filter bag chamber. The working principle of the three-way directional valve is shown in Figure 3-63. The three-way valve of anti condensation anti blowing flat bag dust collector is the most commonly used form of anti blowing dust cleaning mechanism. The characteristic of this valve is that it has a reasonable structure, is tight and does not leak air (with a leakage rate of less than 1%), and the air volume in each room is evenly distributed.

（2） The secondary blocking valve of the anti condensation anti blowing flat bag dust collector (see Figure 3-64). The use of a primary blocking valve and a secondary blocking valve for dust cleaning in the anti condensation anti blowing flat bag dust collector is another form of dust cleaning mechanism. When a bag filter chamber of the anti condensation anti blowing flat bag dust collector is working, the primary valve is open and the secondary valve is closed. When blowing dust, the primary valve is closed and the secondary valve is open, which is equivalent to dividing the three-way reversing valve into two parts. There are two structural forms of the primary and secondary blocking valves. One is similar to a regular butterfly valve, but requires the anti condensation anti blowing flat bag dust collector valve to be tightly closed and the air leakage rate to be less than 5 ^. The other is similar to the three-way reversing valve. The valve is similar, except that the 3 inlet and outlet ports have been changed to 2. The air leakage rate of the anti condensation anti blowing flat bag dust collector valve is less than IX.

（3） Rotary switching valve. The anti condensation and anti blowing flat bag dust collector rotary switching valve consists of a valve body, a rotary spray pipe, a rotary mechanism, a cycloidal pinwheel reducer, a brake, a sealing ring, and a travel switch. The working principle of the rotary switching valve of the anti condensation and anti blowing flat bag dust collector is shown in Figure 3-65. When the dust collector performs chamber back blowing, the rotary spray pipe device, under the action of the control device, rotates the anti condensation back blowing flat bag dust collector according to the program and stays at the position of the cleaning bag chamber air duct. At this time, the filter bag is in an unfiltered state, and the reverse airflow passes through the bag in the opposite direction to shake off the dust. The anti condensation and anti blowing flat bag dust collector program is carried out sequentially until all filter bags are cleaned, and the rotary spray pipe automatically stays at zero position. The anti condensation and anti blowing flat bag dust collector restores the filtering state of the air chamber, similar to the cleaning mechanism of the rotary anti blowing bag dust collector.

（4） Anti condensation and anti blowing flat bag dust collector disc lift valve. There are two types of disc lift valves used for anti condensation anti blowing bag dust collectors. One type is used for negative pressure anti condensation anti blowing flat bag dust collectors, which have the same structure as pulse dust collectors and anti condensation anti blowing flat bag dust collector lift valves. Its appearance is shown in Figure 3-66. One type is used for positive pressure back blowing bag filter, with three inlet and outlet ports. The common feature of anti condensation and anti blowing flat bag dust collectors is that they rely on the valve plate to move up and down to switch the inlet and outlet. Simple construction, reliable operation, and convenient maintenance. The anti condensation and anti blowing flat bag dust collector has a uniform force distribution structure, good anti explosion performance, compact structure, and uses a high-pressure fan to blow back and clean the dust. It is not limited by gas source conditions and uses resistance to automatically control the blowing back and clean the dust, saving energy and extending the use of anti condensation and anti blowing flat bag dust collectors. It can be installed indoors in cold regions and can be installed outdoors in other areas. It can be widely used in many departments such as machinery, casting, mining, smelting, building materials, and grain chemical industry. A new type of high-efficiency pulse dust collector improved on the basis of anti condensation and anti blowing flat bag dust collector, which integrates the advantages of various pulse jet dust collectors with chamber back blowing, overcomes the disadvantages of insufficient cleaning intensity and uneven distribution of inlet and outlet air, and expands the application range. The structure of the anti condensation and anti blowing flat bag dust collector has its own characteristics, which improves the dust collection efficiency, adaptability, and extends the service life of the filter bag of the anti condensation and anti blowing flat bag dust collector. After years of production practice, the equipment has stable operation, small maintenance requirements, and a wide range of combinations, and has been highly praised by users. The anti condensation and anti blowing flat bag dust collector product can be widely used in the dust and smoke collection system of asphalt mixing plants such as crushing, grinding machines, dryers, furnaces, etc. The material of the anti condensation and anti blowing flat bag dust collector filter bag is generally polyester needle punched felt, which allows continuous use temperature ≤ 120 ℃. If the filter bag uses Metas high-temperature needle punched felt, its allowable use temperature can reach 204 ℃. The anti condensation and anti blowing flat bag dust collector can be combined with various specifications of dust collectors according to different specifications of solenoid valves. This series of dust collectors can operate under negative or positive pressure without any changes in their body structure. The anti condensation and anti blowing flat bag dust collector has a dust collection efficiency of over 99.8% and a purified gas dust concentration of less than 100mg/m3. If the anti condensation and anti blowing flat bag dust collector is used in cold areas or when the smoke is below zero, an insulation heating device needs to be added, and the shell should also be subjected to phase strain.
