Baotou automatic pressure filter

Sonic automatic pressure filter is developed in the automatic pressure filter based on a fully automated integrated water treatment equipment with multiple functions; it uses filtration precision of up to 2 m high strength 316L stainless steel sintered mesh , set automatic backwashing and high pressure sterilization scale ultrasonic cleaning technology, and without having to replace the filter element, a thorough cleaning without dead ends, automatic operation, automatic backwash, automatic sewage, also has ultrasonic sterilization, disinfection, scale, lower COD and prevent filter fouling and other features. Widely used in municipal sewage, domestic water, oil field injection water filtration, metallurgy food, farming and other industries landscape. The system safe and reliable operation, easy maintenance, low operating costs. 2 Working Principle an automatic pressure filter (also known as self-cleaning filters, automatic backflushing filter) using foreign technology, according to principles of fluid mechanics, the use of water-driven theory and mechatronics control, with domestic requirements for water quality development of efficient water treatment equipment. When the liquid containing the solid phase into the filter through the inlet pressure, as the filtration process continues, the solid phase inside the liquid impurities are trapped in the surface of the filter element, causing the pressure increases, the filtration resistance increases, the filtration efficiency is decreased. When solid impurities are trapped to a certain extent, the pressure difference on both sides of the filter element reaches the set value, the differential pressure controller provides a signal to the control cabinet, control cabinet and then the received signal is supplied to the electric valve, electric valve automatically open at hydraulic or electromechanical fit the sewage outfall, sewage after a period of time-sensitive, motorized valve automatically close the valve when the pressure difference between the filter element on both sides has reached the set value, repeat the above operation, to filter results. Works two raw water from the inlet into the body, the first outside pressure flows through the coarse screen mode, filter out larger particles of impurities. Coarse screen within fine strainer into the water-pressure, and further small impurities trapped in the water, at the same time, ultrasonic wave synchronization, the liquid microbubble nuclei vibrate when sound pressure reaches a certain value, the bubble will continue to expand, and then suddenly closed, these small bubbles in the bubble collapse rapidly produce high temperature (5000K) high pressure (thousands of atmospheres), and a high speed because the liquid surrounding the bubble into the bubble, but the bubble near the liquid had a strong local shock also formed a local high temperature and pressure to produce ultrasonic sterilization, cleaning, grinding, emulsifying, dispersing, scale, promoting a series of effects of chemical reactions. Frequencies above 20KHz ultrasonic set advanced oxidation, incineration, supercritical water oxidation, and other technology in one, not only to prevent membrane fouling, extend filter backwash cycle, but also has a significant function of sterilization and degradation of organic matter. With the filter media of various pollutants accumulate inside fine strainer, filter channels are blocked, the inlet and outlet pressure is gradually increased, when the pressure reaches a preset value, connected to the inlet and outlet of the pressure transmitter will converts the detected differential pressure signal into 4-20mA current signal transmitted to the control system, (backwash cycle can also be achieved by setting the time), the system automatically starts the motor and backwash stroke high-pressure pump, then the gear drive discharge nozzle mounted on the inside of the filter to do the rotation axis and the horizontal back and forth motion, while the outside of the filter, high-pressure backwash system and sewage installations synchronized action, and was correspondence in without interrupting the normal production of water, Only a small portion of the product water by means of high-pressure filter backwash, backwash water through the filter, along with the release of the filter impurities from the nozzle discharge axis rapid inhalation, finally discharged from the discharge chamber. 3 Applications 1. cooling water, chilled water, cooling towers and other circulatory system. 2. air conditioning, heating and boiler circulating water central heating systems. 3. The circulating water reuse: especially for use in iron and steel, power systems, chemical systems, electronics, food, paper, food industry and other industrial water recycling. 4. Wastewater treatment: sewage treatment plants tertiary treatment, to reduce the cost of fine filtration systems. 5. The lubricating oil, washing liquid, chemical solvents and other similar suspension of the coarse filter and fine filter
