Product Introduction of Small Single Machine Bag Dust Collector:

DMC type single machinebag filterIt is a type of filtering single machine dust collector, and the working principle of the tower is to use fiber filter bags to capture dust in the dust removal equipment. When using a filter bag to filter and separate dust particles, the dusty gas can enter from the outside of the filter bag to the inside, separating the dust on the outer surface of the filter bag, or the dusty gas can flow from the inside of the filter bag to the outside, separating the dust on the inner surface of the filter bag. The dusty gas will complete the entire dust removal process through the filtering principle of the filter bag.

The design structure of a small bag filter mainly includes a box (clean air chamber, bag chamber), ash hopper, support legs (columns), stairs (climbing stairs), railings, platform, filter bag frame, filter bag, lifting valve, switching valve, etc; And the dust cleaning air system (or mechanism), dust cleaning control device, and dust discharge device. If it is a pulse jet type bag filter, it also includes a pulse valve distribution box, a pulse valve, and an air bag. A back blowing bag filter also includes a back blowing fan and valve. A coal mill bag filter also has an explosion-proof door. Small bag dust collectors can be divided into DMC24, 36, 48, 64, 80, 100, 120 and other specifications according to the number of bags.

Detailed description of the structure of a small single machine bag filter:

1. Clean air chamber

The clean air chamber is mainly used to fix the bag cage, filter bag, and air circuit components, and is made in a fully enclosed form. When cleaning the dust, compressed air first enters the clean air chamber and then rushes into the interior of each filter bag. There is an access door at the top for installing and replacing bag cages and filter bags. The clean air chamber is divided into several chambers, separated by internal walls. Each chamber is equipped with a lift valve to switch the filtered airflow. The strength of the clean air chamber should be able to withstand the system pressure.

2. Bag room

The bag chamber is located at the lower part of the clean air chamber and is mainly composed of flower boards, partition walls, and filter bags. The thickness of the flower board is generally not less than 5mm and should be able to withstand the system pressure and the load after the filter bag accumulates dust after reinforcement. The important function of the bag chamber is to accommodate the filter bag, forming a filtering space where the purification of flue gas is carried out.

3. Ash bucket

The ash hopper is located at the lower part of the bag chamber, and its strength should be able to withstand the pressure of the system and the weight of the accumulated ash. The ash hopper is divided into two types: trough type and four diamond type. In addition to accumulating and collecting dust, the ash hopper also serves as a lower intake manifold due to its large internal space. The coarse particles in the airflow first separate and settle in the ash hopper by gravity. The lower outlet of the four diamond type ash hopper is equipped with air locking devices such as flap valves or rotary unloaders, and the ash discharge is completed by screw conveyors or air chutes. The trough type ash hopper is equipped with a screw conveyor, zipper machine, or inclined chute, and is then locked by a flap valve and a rotary feeder. Except for single machine bag dust collectors, ash hoppers should be equipped with maintenance doors. For dust with high viscosity, it is advisable to install a poking or cleaning device in the middle of the ash hopper. For bag dust collectors that handle easily condensing exhaust gas, a heater or vibrator can be installed, and a trough type ash hopper should be used. For coal powder explosion prevention, a four diamond type ash hopper should be used.

4. Backblowing (suction) system

The blowback (suction) system includes a blowback (suction) fan, blowback (suction) duct, cylinder, solenoid valve, pressure measuring device, valve plate, and compressed air pipeline.

5. Filter bag frame

The filter bag frame is one of the important components of the bag filter. The filter bag frame of the pulse type bag filter, also known as the bag cage or skeleton; Internal filter anti blowing bag dust collector with anti collapse ring. The function of the filter bag frame is to support the filter bag, so that it can be tensioned and maintain a certain shape during filtration and dust cleaning, and minimize damage caused by folding. The longitudinal number of pulse bag filter cages varies depending on the diameter and material of the filter bags.

6. Compressed air piping system

The compressed air pipeline system includes air treatment equipment (i.e. air source triad: oil mist filter, water filter, pressure regulating valve), electromagnetic control valve, cylinder (control lift valve), etc. For more bag filter products, please follow our website http://www.btshhb.com
