How to solve these problems in the process of treating cooling water with self-cleaning filter?

Iron and steel industry is an important industry in the national economy. It provides materials and products for machinery, energy, chemical industry, transportation and other industries. 70% of the steel industry's wastewater still comes from cooling water. If so much water is not recycled, the waste will be very serious. At present, there are a lot of water treatment equipment on the market, among which self-cleaning filter is widely used. Self-cleaning filter in the treatment of cooling water will also appear some problems, how to solve it?

Problem 1: Filter deformation

The deformation of the self-cleaning filter screen leads to the normal operation of the equipment, the blockage of the filter screen, the lack of water supply, so that the cooling equipment is damaged due to the lack of water and water pressure.

Solution: Change the water inlet mode and the structure of the filter screen, add baffle at the water inlet, reduce the impact of water directly on the filter screen.

Problem 2: The fouling device assembly is damaged

The motor of the self-cleaning filter and the dirt suction device are connected by the lead screw through the pin, copper sleeve and other parts, and the upper and lower travel of the dirt suction device is controlled by the limiting device. Because the fault of the limiting device leads to the breaking of the pin, the damage of the copper sleeve and the burning of the motor, the dirt suction device can not operate normally.

Solution: The running track of the pollution absorber assembly is changed from axial rotation to radial rotation to avoid the motor burning, lead screw and pin breaking, copper sleeve damage and other failures caused by frequent limit.

Problem 3: Self-cleaning filter leaks

Water leakage problems generally appear in the drive shaft part of the filter; First, the transmission shaft sealing ring material or specifications do not meet the requirements caused by; Second, the sealing ring after a long time of operation appears wear, causing the transmission shaft and filter body between the seal is not strict and water leakage.

Solution: As long as the replacement of the corresponding specifications of the sealing ring can be solved.

Problem four: Impurities enter the circulating water system, resulting in screen blockage

In spring, there is large sand, dust and catkins. These sundries enter the circulating water system through the cold water tower, resulting in the blockage of the self-cleaning filter screen and the normal use of the equipment.

Solution: A protective net is installed on the cool water tower to avoid the normal use of the self-cleaning filter screen which is blocked by the dust entering the circulating water system through the cool water tower.

In view of the current situation of water resources utilization in the steel industry, Aite Environmental Protection launched the overall solution of different water quality, which has a good effect on the recycling of water resources. In the future, Aite environmental protection will continue to strengthen the production and research of products, continue to boost the comprehensive utilization level of water resources in our country!
