The second driving part 340 is connected to the second rod 320. The second driving part 340 can adjust the length of the second rod 320 inserted into the stripper tube 100. Preferably, the length inserted into the gas stripping tube 100 may refer to the length of the outer wall of the gas stripping tube 100 or the hollow portion inside the gas stripping tube 100. The second driving unit 340 is provided so as to feed at least a part of the second rod 320 into the stripper tube 100. The second drive section 340 is arranged in such a way as to feed at least part of the second rod 320 into the gas stripping tube 100 until the free end of the second rod 320 abuts against the inner wall of the gas stripping tube 100.

The controller 400 may be configured to: the supply of compressed gas into the stripper tube 100 by the compressed gas source 860 continues while the first and/or

second rods

310, 320 are removed. The first preset time period may be set by an operator or the controller 400 according to the quality of the raw water. For example, the first preset time period may be 0.5h, 1h, 2h, or 3 h. If the upstream first rod 310 is removed first, the contaminants that would otherwise adhere to the first rod 310 flow directly to the downstream second rod 320, resulting in an increased likelihood of blockage of the stripper tube 100. The invention can at least realize the following beneficial technical effects by adopting the mode: in the present invention, the second rod 320 is moved out of the gas lift 100 first, the dirt attached to the second rod 320 is separated from the second rod 320 and moves upward to reach the separation region 210, and the first rod 310 is moved out after the second rod 320 is moved out, so as to reduce the possibility of blockage of the gas lift 100.

According to a preferred embodiment, the first rod 310 may be inserted into the stripper tube 100 in a diagonally upward manner. The invention can at least realize the following beneficial technical effects by adopting the mode: the first rod 310 is inserted into the stripper tube 100 in an obliquely upward manner to allow the flow material and the rods in the stripper tube 100 to exert an obliquely upward force on the dirt in the direction of the rods of the first rod 310 as the first rod 310 is removed from the stripper tube 100 to facilitate the dirt on the first rod 310 being carried away from the first rod 310, particularly floe dirt, by the flow material in the stripper tube 100. Preferably, the first rod 310 is angled from horizontal when the washer is in place. The acute included angle between the first rod body 310 and the horizontal direction is 5-45 degrees, and particularly preferably 10-30 degrees.

According to a preferred embodiment, the second rod 320 may be inserted into the stripper tube 100 in a diagonally upward manner. The invention can at least realize the following beneficial technical effects by adopting the mode: the second bar 320 is inserted into the stripper tube 100 in an obliquely upward manner to allow the flow material and bars within the stripper tube 100 to exert an obliquely upward force on the dirt in the direction of the bars of the second bar 320 as the second bar 320 is removed from the stripper tube 100 to facilitate the carrying of the dirt on the second bar 320 away from the second bar 320, particularly floe dirt, by the flow material within the stripper tube 100. The second rod 320 forms an angle with the horizontal direction. The acute included angle between the second rod 320 and the horizontal direction is 5-45 degrees, and particularly preferably 10-30 degrees. Preferably, the distance between the portion of the first rod 310 inserted into the gas stripping tube 100 and the portion of the second rod 320 inserted into the gas stripping tube 100 is 10mm to 1500mm, and particularly preferably 100mm to 200 mm. The spacing between the first rod 310 and the second rod 320 is calculated as the minimum distance in space between the portion of the first rod 310 inserted into the gas lift tube 100 and the portion of the second rod 320 inserted into the gas lift tube 100.

According to a preferred embodiment, the first rod 310 and the second rod 320 may each be inserted into the stripper tube 100 in a diagonally upward manner. Preferably, the acute angle of the second rod 320 located downstream of the first rod 310 with respect to the horizontal may be greater than the acute angle of the first rod 310 with respect to the horizontal.

According to a preferred embodiment, the sand particles with impurities trapped therein are lifted from the lower part of the filter bed 600 by the lifting action of the air in the lifting pipe, and then cleaned and fall back to the upper part of the filter bed 600, so that the filter material continuously moves downwards, the air, the water and the filter material are in a turbulent state in the filter material lifting pipe, the filter material is stirred vigorously and rises, the filter material collides and rubs with each other, and suspended substances attached to the surface of the filter material are collided and washed away, so that the filter material is purified and cleaned. When the mixture of the filter material, the suspended matter and the water is discharged from the lift pipe along with the air and enters the material washer, the air is released from the water and discharged out of the container 500 due to the increase of the pipe diameter of the separation chamber and the reduction of the flow rate and the pressure of the water body. The suspended matter and the filter material lose the support of air, and due to the difference of the densities of the suspended matter and the filter material, the filter material quickly sinks into the cleaning chamber, and the filter material is collided and rubbed again in the tortuous channel to be purified and cleaned. The washed suspended matters rise into the separation chamber and are discharged by a sewage discharge pipe under the support of rising water flow. And the washed filter material continuously falls down and falls back to the upper part of the sand filter layer. Therefore, the filter material on the upper part of the filter bed 600 is always kept in a clean state, and moves downwards along with the lifting of the filter material on the lower part of the filter layer, and suspended matters entering the filter layer along with raw water are continuously intercepted. Therefore, the filter material with the impurities trapped is cleaned and regenerated, and the filter material above the outflow port of the raw water can keep lower suspended matter interception amount, so that the pressure loss of water flow is small, and the power cost is saved.

According to a preferred embodiment, the filter material has a density greater than the density of water. At least a portion of the filter material collects under the force of gravity within the vessel 500 to form a filter bed 600 for filtration. Preferably, the filter material may be a porous filter material. The filter bed 600 formed by the stack of filter material allows the suspended matter to be separated from the liquid. Preferably, the filter material may employ at least one of quartz sand, activated carbon, and activated coke. Preferably, the particle size of the filter material can be 0.2-2 mm. Preferably, the grain size of the filter material can be 0.5-1.5 mm. Preferably, the particle size of the filter material can be 0.7-1.1 mm. Particularly preferably, the filter material may have a particle size of 0.9 mm.

According to a preferred embodiment, a scrubber may include an stripper tube, a separation zone, and a tortuous path. The tortuous path may be provided with a plurality of intersecting non-linear channels that increase material friction. The filter material lifted by the compressed air from the air stripping pipe descends in a friction mode from a plurality of nonlinear filter channels under the action of gravity. The washing waste water flowing based on the difference in the liquid level between the vessel and the separation zone and the pressure of the compressed air can be discharged from the washing waste water pipe through the separation zone. Preferably, the controller controls the pumping mechanism of the raw water and the pumping mechanism of the washing wastewater to ensure that the liquid level between the container and the washer is higher than that of the separation area of the washer. Therefore, the washing material waste water is prevented from entering the container from the bent channel, and the filtering liquid can move upwards from the bent channel to enter the separation area, so that dirt separated from the filtering material in the bent channel is brought into the separation area.

According to a preferred embodiment, the washer may comprise a separation zone 210 and a washing zone 220. The separation zone 210 and the washing zone 220 may be in communication with each other. The cleaning zone 220 may include an inner member 231 and an outer member 232. The inner 231 and outer 232 members may together form a tortuous path 230 for the filtered sand lifted by the stripper 100 to the washer to fall circuitously. The inner member 231 may be provided with a first flap 233 protruding toward the outer member 232. The first flap 233 may be disposed along a surface of the inner member 231 in a spiral manner. The outer member 232 may be provided with a second flap 234 extending toward the inner member 231. The second flap 234 may be helically disposed along the surface of the outer member 232 in a helical manner. The upper surfaces of the first and second flaps 233 and 234 are inclined downward. With the inner member 231 and the outer member 232 in place, at least part of the contours of the first flap 233 and the second flap 234 may coincide with each other when projected towards a horizontal plane, such that at least part of the filter material falling from the tortuous passage 230 may fall from the surface of the first flap 233 to the surface of the second flap 234 or may fall from the surface of the second flap 234 to the surface of the first flap 233.

Preferably, at least one of the inner member 231 and the outer member 232 is movable relative to the other to unblock the occluded site by movement of at least one of the inner member 231 and the outer member 232 when occlusion of the tortuous passageway 230 occurs. Preferably, at least one of the inner member 231 and the outer member 232 is reciprocally movable back and forth within its range of motion to unblock the blocked site by cyclically changing the shape of the tortuous passage 230 by the motion of at least one of the inner member 231 and the outer member 232 when the blockage of the tortuous passage 230 occurs. For example, the inner member 231 may be slidably disposed relative to the stripper tube 100. The inner member 231 may slide up and down by the power provided by the third driving part 235 to unblock the meandering passage 230. Preferably, the third driving part 235 may be configured to define a movement range of the inner member 231 when the inner member 231 is powered to move the inner member 231 within a movement range that does not contact the outer member 232. Preferably, the third driving part 235 is configured to define a movement range of the inner member 231 to move the inner member 231 within a movement range that does not contact the outer member 232 when power of reciprocating back and forth is supplied to the inner member 231.

For example, at least one of the inner member 231 and the outer member 232 may be linearly moved relative to the other to change the shape of the tortuous passage 230 and thereby open the clogged portion. For another example, at least one of the inner member 231 and the outer member 232 can be rotated relative to the other to open the clogged part. For example, the inner member 231 may be connected to the third driving part 235 and driven by the third driving part 235. The outer member 232 may be connected to the fourth driving part 236 and driven by the fourth driving part 236.
