Oil bath air filter zksg

In the working environment with high dust concentration in the air, the dust removal filter device used in general air compressors is mostly screen-type secondary dust removal paper and fiber material filtration. The screen-type secondary dust removal is adopted, the dust collection area is small, and only larger dust can be filtered, causing fine dust to enter the air compressor through the suction pipe. Air valve discs, valve seats, springs and other parts are often disassembled, cleaned and replaced. This results in high cost of materials and accessories, many failures, and low equipment efficiency. However, when paper and fiber materials are used for filtration, dust accumulation is easy to block, and frequent shutdowns are required to replace filter materials. Increase the labor intensity of workers.

We aimed at the comparison of the commonly used screen type, Raschig ring type, paper and fiber filters; and designed and produced a type of oil bath air muffler filter, which is a combination of cyclone, oil bath, oil film and filter A variety of dust removal methods are integrated. A new type of high-efficiency low-noise air silencing filter combined with a silencing device. The dust filtering efficiency is 98%, the filtering accuracy is less than 8µ, and the resistance is 50 mm water column. Reduce the noise of the suction port by 35 decibels (A). It significantly reduces environmental noise, prolongs the life of the air compressor, reduces maintenance workload, reduces labor intensity and saves energy consumption Wait.

Schematic diagram of filter principle structure

The filter is cylindrical, and the cylinder is divided into three parts: the outer cylinder, the inner cylinder, and the air outlet pipe. The upper part of the inner part is a swirling plate (or guide vane) and a filter screen, and the lower part is connected to the outer cylinder, and the bottom of the cylinder is filled with compressor oil (waste oil). Air is sucked into the outer cylinder from the tangential direction and rotates at a high speed. The dust particles in the airflow are separated by centrifugal force. Then the air flow traverses the oil surface, and the oil level fluctuates. Part of the oil mist is entrained and rotated by the air flow and adheres to the inner cylinder wall to form an oil film. The dust particles in the air flow are captured by the oil film. The oil film flows back along the wall and becomes a drooping oil curtain. When the air passes through the oil bath, some dust particles are captured. The airflow rotates and rises in the inner cylinder, passes through the swirling plate and then intensifies the rotation, throwing a part of the oil droplets entrained in the airflow into the oil return groove and flowing into the bottom of the cylinder from the oil return pipe, and a part of it flows back along the inner cylinder wall to coat the oil film on the cylinder wall. The collected dust is washed down to the bottom of the cylinder, producing a new oil film. Then the airflow passes through the filter again to filter out smaller dust particles and oil droplets, achieving the purpose of filtering the air. The noise of the suction port is mainly the mechanical noise generated by the air compressor when it is running, and the noise and airflow noise transmitted to the suction port through the pipe and gas, which affect the surrounding environment. The ZKSG type combined air muffler filter adopts tangential air intake, and the airflow is damped and divided by the oil film, oil bath and filter screen, and it has been expanded many times, and there is a muffler cap on the top. Good silencing effect, thereby greatly reducing the noise of the suction port.
