Introduction:
Gas turbines, air compressors, blowers and other aerodynamic equipment will be worn and corroded after they inhale the air which contains dust.
The dust will scale on the surface of the fan blade, resulting in the imbalance of the dynamic balance of the rotor in the equipment, the precision is reduced, the working life is greatly shortened; The harmful chemical composition in the dust will cause rust and corrosion of the equipment.
Therefore, the aerodynamic equipment must be equipped with high precision air filter to ensure the clean air which is sucked into the aerodynamic equipment. In this way, the inside of the aerodynamic equipment will never be worn by dust, and the fan blade has no obvious scaling for many years.
LFZK series self-cleaning air filter is improved on the basis of the domestic and foreign similar air compressor intake requirements, so the current product performance can fully meet the air intake requirements of industrial gas turbine, blast furnace blower, air compressor.
Advantages & Features:
1. We can add dust collection box, dust screen, and water wash dust removal device at the bottom of the equipment according to user requirements to solve secondary pollution.
2. The equipment is controlled by an intelligent distributor, and there are four self-cleaning methods, namely (1) Timing; (2) Pressure Difference; (3) Manual; (4) Remote.
3. The equipment can realize the automatic cleaning of air filter elements so that the equipment runs as usual, without affecting the normal work of other filter elements.
4. It can work normally under the condition of 100% relative humidity.
5. The filter area is large, the flow rate is low, the resistance loss is small, and the resistance loss can be shown on liquid crystal display.
6. Service life of filter element is long. Under normal environmental conditions, the replacement cycle of the filter element can reach 1-2 years.
7. High degree of automation, the main components are imported parts, and it can realize unmanned operation.
8. Back blowing gas consumption is less, generally 0.1 ~ 0.3m3/min(inhalation state); The pressure is 0.4 ~ 0.6Mpa.
9. The equipment is light and the weight is 1/3~1/2 of the bag type dust collector.
10. Reasonable design, no bending design, high-rise block type combination, easy to install.
11. We can carry out non-standard design and production according to customer requirements.
Structure Specification:
1. Core component: air filter cartridge / air filter element
2. Pulse jet cleaning: gas storage device + pulse solenoid valve
3. Automatic dust removal control system: programmable control instrument / PLC control cabinet
4. Pre-filtration unit: front primary filter screen
5. Differential pressure control unit: pressure difference transmitter
6. Fixed component of filter element: rod
Working principle:
1. Filter process:
Under the suction of the air compressor, the dusty air flows through the primary coarse filter box first, and then flows through the high efficiency filter cartridge; due to gravity inertia, diffusion, contact retention and other comprehensive effects, the dust in the air is adsorbed on the surface of the high efficiency filter cartridge, and the clean air flows through the seal washer and then flows into the Ventri tube and then flows into the clean air chamber. All the clean air is merged into the air collecting port in the clean air chamber, and then inhaled from the clean air port pipe by the air compressor.
2. Self-cleaning process:
After the dusty air is filtered, the dust is adsorbed on the surface of the high efficiency filter cartridge, and the reverse blowing self-cleaning process is carried out by PLC according to the set time sequence. When the resistance value exceeds 600 pa, the reverse blowing self-cleaning process is controlled by PLC according to the differential pressure sequence (the reverse blowing time is 0.1-0.2 seconds). Other high efficiency filter cartridges work as usual and dust is blown down during the reverse blowing self-cleaning process.
Application:
*It is widely used in various types of air compressor stations, compressor rooms and so on. Several small capacity compressors can be equipped with one self-cleaning air filter, a large capacity compressor can be equipped with one self-cleaning air filter.
*It is widely used in various industries oxygen stations. It is installed at the entrance of the air compressor to filter and purify the inhaled air.
*It is widely used for blast furnace blowers in iron and steel plants. It is installed at the inlet of the fan to protect the fan impeller. *It is widely used for various capacity gas turbines. It can provide clean power source for gas turbines.
*It is widely used for long time running diesel engines. It can provide clean air power for diesel engines.
*It is widely used for air conditioning system in chemical fiber, textile, electronics and other industries. It can provide clean circulating air for clean workshop.
