Applicable industries and equipment operating conditions of the product

1. Metallurgical industry: suitable for full flow filtration of continuous casting water, high-pressure phosphorus removal water, and clean circulating water, as well as system side filtration and nozzle protection, to intercept iron oxide scale and solid particles, prevent nozzle blockage, and ensure continuous metallurgical production.

2. Power industry: used for steam turbine cooling water filtration, wet electrostatic precipitator circulating ash water purification, cooling tower water side filtration and full flow filtration, removing water rust and suspended solids, and protecting heat exchangers and cooling tower fillers.

3. In the agricultural field: large-scale sprinkler and drip irrigation system water source treatment, removing weeds and sediment from the water source, preventing drip irrigation holes from clogging, and reducing the frequency of irrigation system maintenance.

4. Chemical and petrochemical industries: pre-treatment of process circulating water and production make-up water, interception of pipeline corrosion products and suspended impurities, protection of precision process equipment such as heat exchangers and pumps and valves.

5. Light industry and manufacturing industry: Water filtration for production in the steel, electronics, textile, paper, food, pharmaceutical, and automotive industries serves as a pre security unit for water treatment, stabilizing the incoming water quality and reducing the pollution load of back-end membranes and precision equipment.

The fully automatic self-cleaning filter is different from Bag Filter and security filter. It does not require regular replacement of filter elements and relies on mechanical brushes to clean the wedge-shaped filter online, without the need for manual disassembly and cleaning throughout the process. The equipment automatically identifies the degree of blockage under continuous water supply conditions, autonomously starts the cleaning and sewage discharge process, and is suitable for industrial circulating water systems with high flow and continuous operation. It is the preferred pre filtration equipment for cost reduction and efficiency improvement in large-scale water treatment projects.

Core competitive advantages of the product

1. Online cleaning, uninterrupted water supply: Cleaning and sewage operations do not require shutdown or water interruption, and downstream production processes are not affected by filtration maintenance, meeting the requirements of continuous industrial production.

2. No consumables design, low long-term operation and maintenance costs: The wedge-shaped stainless steel filter screen can be used for life, without the need to regularly purchase replacement filter cartridges and bags, with only a small number of vulnerable parts, greatly reducing consumables expenses.

3. Intelligent multi-mode control: supports three cleaning modes: differential pressure triggering, timed triggering, and local manual. It can be connected to the DCS system to achieve remote monitoring and automation linkage.

4. Low pressure loss and excellent water-saving performance: normal operating pressure loss ≤ 0.018MPa, sewage water consumption less than 1%, saving water resources while ensuring cleaning effectiveness.

5. Reliable structure, suitable for complex water quality: The vertical compact tank structure is impact resistant and corrosion-resistant, and can cope with high sediment and high suspended solids in raw water, adapting to working conditions with large water quality fluctuations.

6. Easy installation and operation: The whole machine is designed with integration, and can be put into use by on-site flange docking. It operates automatically with minimal manual intervention and simple operation management.

Frequently Asked Questions (FAQ)

Q1: What is the working principle of the fully automatic self-cleaning filter?

A: The water to be treated enters the filter cylinder, and impurities in the water are trapped on the surface of the wedge-shaped stainless steel filter. As the impurities accumulate, the pressure difference between the inlet and outlet gradually increases; When the pressure difference reaches the set threshold, the controller starts the motor to drive the brush body to rotate and clean the filter screen, while opening the drain valve to discharge impurities. The entire cleaning process lasts for tens of seconds, during which the system maintains uninterrupted water supply. After cleaning, the equipment automatically resets and continues to enter the filtering process.

Q2: What are the advantages of this filter compared to filter cartridge filters?

A: The core advantage is the non consumable filter material. The filter element needs to be regularly purchased and replaced, while the wedge-shaped stainless steel filter screen of this equipment can be used for a long time; At the same time, the equipment supports online cleaning without the need to shut down or dismantle tanks, making it suitable for 24-hour continuous operation of high flow circulating water systems with lower long-term operation and maintenance costs.

Q3: What types of cleaning trigger methods does the device support?

A: It has three control modes: differential pressure, time, and manual. The differential pressure mode automatically starts cleaning based on the clogged filter screen and differential pressure; The timed mode automatically cleans according to the preset cycle; Manual mode can trigger on-site cleaning with one click; The equipment can be connected to the DCS system to achieve remote linkage control.

Q4: Is it necessary to stop the system water supply during cleaning?

A: No need. The equipment maintains uninterrupted main water supply during the cleaning and sewage discharge stage, without interrupting downstream process water, which is the core advantage of continuous production type factory circulating water treatment.

Q5: What is the approximate water consumption for sewage discharge and what is the water-saving effect?

A: The sewage consumption is less than 1%, the single cleaning time is short, and compared with traditional side filtration and backwashing equipment, the water resource loss is extremely low. Long term use in large-scale circulating water systems has significant water-saving benefits.
