Application of Automatic Backwash Filter in Industry

JX Filtration September 11, 2022 Automatic Backwash Filter

Background:

With the automation of the manufacturing industry, the role of labor in the production process is getting smaller and smaller, which puts forward higher requirements for the reliability and safety practicability of the equipment itself. Using traditional Y-type filters, operators face the dangers of high-altitude work, high-temperature work and deep trench work. The automatic backwash filter is used, which basically does not require manual participation during maintenance, which increases the safety and the filtering effect is better than before. Automatic backwash filters are used to filter and intercept particulate impurities in low viscosity liquids. Its excellent structural design and automatic cleaning function bring users stable and reliable control performance, and also greatly reduce operation and maintenance costs.

Industry application:

1. Metallurgical industry
Due to the relatively high temperature of the working environment, large-scale hydraulic and lubricating systems in the metallurgical industry require high-power heat exchangers. The heating medium is oil and the cooling medium is water. Using ordinary water for a long time will cause a large amount of scale to adhere to the water channel of the heat exchanger, which directly affects the amount of water used for cooling, resulting in a decrease in the heat exchange effect. The use of an automatic backwash filter will protect the heat exchanger well, ensure that the water entering the heat exchanger achieves a high degree of cleanliness, and maintain the normal use of the cooling system. There are also hot-rolled steel plate equipment, industrial descaling nozzle protection filters, and automatic backwash filters are widely used, which ensures that the water entering the nozzle is clean and greatly reduces the douse rate of the nozzle. The same is true for the rolling mill emulsion system. Installing this filter before the pump inlet can effectively prolong the service life of the pump and save maintenance costs.

2. Car Manufacturing
It can be installed in the main lubricant pipeline for centralized filtration or separate filtration of each equipment. To ensure a longer cycle of cooling lubricants (cutting fluid, cleaning fluid), prolong the service life of tools, improve processing efficiency and processing quality, reduce environmental pollution and the cost of processing and replenishing cooling lubricants.

3. Power plant
Thermal power plants are used in the filtration of industrial cooling water, sealing water and dedusting spray water, and pre-filtration of boiler feed water; in hydropower plants, they are used in bearing cooling water, generator oil cooling water and floating ring sealing water, all of which are effectively protected. Cleaning of heat exchange elements and working elements extends their service life

4. Heat concentration
The circulating water used for heating the households passes through thousands of households. Due to the replacement of the radiator in the user's home and the long-term non-cleaning, a large amount of scale and impurities will inevitably remain. If no filtering treatment is performed before recycling and heat exchange, it will definitely lead to blockage and wear of the heat exchanger, resulting in heat exchange. The efficiency is reduced, and the automatic backwash filter is applied, which not only reduces the labor maintenance cost, but also strengthens the quality of the circulating water and ensures the warmth of thousands of households.

5. Municipal environmental protection
These include desalination of sea water, sewage discharge treatment, microfiltration and ultra-microfiltration sterilization pretreatment, etc., which filter out suspended particles in the water body, protect subsequent equipment, and can be widely used as a security filter.

6. Paper mill
The papermaking process requires a lot of water for equipment sealing, spraying, and cooling. The application of backwash filters can effectively protect the nozzles, meshes, vacuum pumps, etc. in the papermaking equipment, reducing the blockage and wear of these equipment. . The backwash filter is also widely used in the protection of the suction pump of the snow making machine, the pipeline flushing water in the oil and gas exploitation, the drinking water in the food industry and the cooling circulating water in the chemical industry, etc.
