Fertilizer plant pulse bag house filter dust collector structure

The LPMC type gas shock pulse bag dust collector adopts a compartmental assembly structure and is composed of the dust collector body, inlet and outlet air box body, pulse injection dust cleaning device, ash hopper and ash unloading mechanism, compressed air pipeline system, etc.
The dust collector body includes components such as a clean room, a filter room, compartment partitions, and access doors. The cleaning room is equipped with flower panels, poppet valves, and blow pipes, and filter bags and filter bag frames are installed in the filter room.
The air inlet and outlet box includes the air inlet and outlet ducts and the middle partition. For single-row models, the air inlet and outlet boxes are on one side; for double-row models, the air inlet and outlet boxes are arranged in the middle of the two rows; the A series is smaller, with the air inlet in the ash hopper and the air outlet in the clean room.

Fertilizer factory dust collector filter bags self-cleaning working principle

The pulse injection self cleaning device includes pulse valve, air bag, lift valve cylinder, solenoid valve, etc. The ash hopper and ash discharge mechanism include ash hopper, screw conveyor or air conveying trough and double-layer flap ash discharge valve.

When the dust collector control system sends a dust cleaning control signal, the dust cleaning process is started. First, close the poppet valve of the first chamber to cut off the air flow through the filter chamber.
The chamber exits the filtering state (offline), and then opens the pulse valve. The released high-pressure compressed air carries the air from the clean air chamber and sprays it into the filter bag at high speed, causing the chamber to exit the filtering state (offline).
The filter bag suddenly expands and deforms, which shakes off the dust attached to the surface of the filter bag, and the dust falls into the ash hopper. After a period of settling, the controller opens the poppet valve and restores the chamber to the filtration state (online).
Then start the cleaning process of other rooms in sequence until the entire cleaning cycle is completed.

How does Fertilizer Industrial pulse jet dust collection systems operation work?

The dust-containing gas enters from the air inlet in the air inlet and outlet box of the dust collector, and is diverted to the ash hopper through the inclined partition.
At the same time, the air flow speed slows down. Under the action of inertia, the coarse dust particles fall into the ash hopper, and the fine dust particles are deflected with the air flow.
When it enters the filter chamber upwards, under the filtration effect of the dust cake on the surface of the filter bag, the dust particles are blocked on the outside of the filter bag.
The purified gas enters the clean room from the inside of the filter bag, and is collected into the air outlet box through the opened poppet valve. It is discharged into the atmosphere through the system fan.

Harbor freight Bag filter housing collector dedusting self cleaning device

The harbor freight pulse cleaning of tongli dust collector is controlled by the controller, which provides pressure difference control, timing control and manual control.
The pressure difference control mechanism means that as the filtration process continues, the dust accumulated on the outer surface of the filter bag continues to accumulate, and the operating resistance of the dust collector gradually increases.
When the resistance of the grizzly dust collector filter bag reaches the preset value, a control signal is issued to start dust cleaning. After receiving the signal, the dust collector repeatedly performs the cycle of “back-flushing and cleaning-sedimentation-filtration” room by room until the resistance of the dust collector drops to the set lower limit of resistance.
The pressure difference control mechanism can always stabilize the dust collector resistance within a certain range, and the dust collector maintains the best dust removal efficiency and the lowest operating energy consumption.
Timing control refers to arranging timing to implement backflush based on empirical values. It is usually used to deal with systems with relatively stable working conditions. Generally, the duration of the air-stop blowing in the grizzly dust collector filter bag and the time interval of the blowing in different chambers can be adjusted through operational observation during the trial operation stage.
The operating temperature is ≤120°C; when using aramid needle felt (Nomex), the allowed operating temperature can reach 200°C; when exceeding the allowable temperature of each filter material, cooling measures should be taken before the flue gas enters the grizzly dust collector filter bag.

Allowable concentration at the entrance of harbor freight Bag filter housing dust collector

Due to the special structure of this dust collector and the use of air-stop pulse jet cleaning (offline dust cleaning), the allowable concentration at the inlet is higher than that of traditional pulse jet dust cleaning (online cleaning) dust collectors. The dust concentration allowed in the inlet gas of series A (small) of this dust collector is 200g/m2 (standard), and other series B, C, and D can allow up to 1000g/m2 (standard).

Dust, fume, mist dust bag filter collection systems technical calculation and model selection:

1. Selection of bag filter dust collector air volume:

The filtration wind speed refers to the amount of air passing through the filter material per unit area in unit time. The unit is m3/min/m2. If the area factor is removed, it is simplified to m/min.
The filtration wind speed is a key parameter that affects the performance of the dust collector. It not only determines the size of the dust collector, but also has a great impact on the dust collector resistance, dust removal efficiency, dust cleaning efficiency and filter bag service life.
The selection of filtration air speed and volume should be determined by comprehensively considering the application conditions, characteristics of flue gas and dust, temperature and humidity, dust concentration, dust cleaning method, selected filter material and other factors. LPMC air shock pulse dust collector generally recommends 0.7~0.9 m/min filter wind speed.

2. How to calculate the filter area of bag dust collector

S=Q/(V.60)(m2)
S——Calculated value of total filtration area of dust collector, m2;
Q——The processing air volume of the dust collector, m3/h;
V——filtration wind speed of dust collector, m/min
Based on the filtration area value calculated by the above formula, check the model and performance table, select the LPMC air shock pulse bag dust collector model with a similar filtration area, and then calculate the filtration wind speed based on the filtration area of the dust collector; if the calculated filtration wind speed is within acceptable Within the selected range, the dust collector model can be determined.

3. Selection of dust collector filter bag materials

The selection of filter material is closely related to the operating temperature. The allowable dust-containing gas temperature at the inlet of the dust collector is different, and the filter material is also different. When using film-coated polyester needle felt filter media, continuous use is allowed.

Should I buy a new bag house filter dust collector or used?

The answer is buy a new one. one story short, a used bag filter is not cheap, while spending a little bit more and get a beand new efficient bag dust filter why not?
