Embodiment Three

A method for using a separator with the functions of separating particles and cleaning the filter element proposed by the present invention includes the separator with the functions of separating particles and cleaning the filter element described in Embodiment 2, and specifically includes the following steps:

S1, pass the high-pressure water into the separation chamber 104 from the two elbows 4, and the elbow 4 changes the flow direction of the high-pressure water so that the high-pressure water flows along the inner wall of the separation chamber 104 to form a vortex;

S2. Particles in the high-pressure water forming a vortex flow enter the funnel 11 along the inner wall of the separation bin 104, and sink into the dirt collection bin 105 along the inner wall of the funnel 11;

The high-pressure water forming a vortex flow contacts the filter element 8 and is filtered. The filtered water enters the liquid inlet chamber 102 and is filtered through the filter part 3 of the lower layer, and then enters the filter chamber 101 to contact with activated carbon for purification. The purified water passes through the upper layer. The filter part 3 enters the water outlet chamber and is finally discharged from the water outlet 2;

S3, during sewage discharge, start the ultrasonic generator 10 and open the sewage valve;

When the sewage valve is opened, the pressure in the sewage collection chamber 105 and the separation chamber 104 is decompressed instantaneously, and the instantaneous decompression forms pulse-like shaking and the water in the collection tank of the inlet chamber 102 flows back, and the filter element 8 is recoiled;

The ultrasonic generator 10 converts the sound energy of the power ultrasonic frequency source into mechanical vibration through a transducer, and radiates ultrasonic waves into the tank by cleaning the tank wall, so that the microbubbles in the liquid in the tank can maintain vibration under the action of sound waves ;

When the sound pressure or sound intensity is reduced to a certain extent by the pressure, the microbubbles expand rapidly and then close suddenly; shock waves are generated at the moment the microbubbles close, causing a pressure of 1000-1020Pa and local temperature regulation around the bubbles.

In summary, in the present invention, the water to be separated is transported from the two elbows 4 to the separation chamber 104 by means of high-pressure pumping, and the elbow 4 changes the flow direction of the high-pressure water so that the high-pressure water follows the inner wall of the separation chamber 104 The flow forms a vortex, using physical principles to slowly sink the particulate impurities in the high-pressure water into the sewage collection bin 105 along the inner wall of the separation bin 104 and the inner wall of the funnel 11, so as to realize the solid-liquid separation of the high-pressure water;

The relatively clean water of the vortex core is separated again through the filter element 8, that is, the high-pressure water forming the vortex flow contacts the filter element 8 and is filtered. Since the water flows in a swirling flow, the flowing water can clean the filter element; the filtered water enters the liquid inlet chamber 102 and pass through the filter part 3 of the lower layer to filter and then enter the filter chamber 101 to contact and purify with activated carbon, the purified water enters the water outlet chamber through the filter part 3 of the upper layer, and finally discharges from the water outlet 2;

When the sewage valve is opened, the pressure in the sewage collection chamber 105 and the separation chamber 104 is decompressed instantaneously, and the instantaneous decompression forms pulse-like shaking and the water in the collection tank of the inlet chamber 102 flows back, and the filter element 8 is recoiled;

During the recoil process of the filter element 8, the ultrasonic generator 10 converts the sound energy of the power ultrasonic frequency source into mechanical vibration through the transducer, and radiates the ultrasonic wave into the tank by cleaning the tank wall. Due to the radiation of the ultrasonic wave, the tank The microbubbles in the inner liquid can keep vibrating under the action of sound waves;

When the sound pressure or sound intensity is reduced to a certain extent by the pressure, the microbubbles expand rapidly and then close suddenly; shock waves are generated at the moment the microbubbles close, causing a pressure of 1000-1020Pa and local temperature regulation around the bubbles. The huge pressure generated by the ultrasonic cavitation can destroy the insoluble dirt and make them differentiate in the solution. On the one hand, the above method can destroy the adsorption of the dirt and the surface of the filter element 8, and on the other hand, it can cause the fatigue damage of the dirt layer and be rejected. The effect of cleaning the dirt on the surface of the filter element 8 is achieved; the vibration of the gas type micro-bubbles scrubs the solid surface, and once there is a gap between the dirty layer and the solid surface, the air bubbles immediately drill into the above-mentioned gap and vibrate to make the dirty layer fall off from the solid surface ;

Due to the effect of cavitation, the two liquids quickly disperse and emulsify at the interface. When the solid particles are wrapped and adhere to the surface of the filter element, the oil is emulsified and the solid particles fall off by themselves. The variable sound pressure forms a jet and impacts the filter element 8. At the same time, due to nonlinear effects, acoustic flow and micro-acoustic flow will be generated, while ultrasonic cavitation will generate high-speed micro-jet at the interface between solid and liquid. All these effects can destroy dirt. , Remove or weaken the boundary dirt layer, increase stirring and diffusion, accelerate the dissolution of soluble dirt, and at the same time, the vortex water separates and drains the dirt away to keep the filter element 8 clean.

The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and within the scope of knowledge possessed by those skilled in the art, various Variety.
