Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water distribution devices, in particular to a filter water distribution method, system and water treatment equipment. BACKGROUND

[0002] The water distribution device of the filter is a device for uniformly distributing water on the working surface. Its main function is to uniformly distribute water flow and prevent filter material loss. In the filtration process, the water distribution device first ensures that the water flow is uniformly distributed to the surface of the filter core to prevent local flow from being too large and causing damage to the filter core or uneven filtration effect. When the water flow passes through the filter core, the fiber weaving structure of the filter core forms countless micro channels and pores. Particulate matter, colloids and microorganisms suspended in the water cannot pass through the water flow because their size is larger than the filter core pores. They are intercepted and retained on the surface and internal pores of the filter core by the filter core fibers, thereby achieving the filtration effect. The water distributor has the characteristics of compact structure, small floor area, high economic benefit, fully enclosed structure, positive pressure operation, no influence caused by waste gas overflow, uniform water distribution, good hydraulic stirring effect, no blockage, low energy consumption, high efficiency, continuous automatic operation, easy management, etc. It is widely used in various filtration equipment such as mechanical filtration equipment, activated carbon filtration equipment, softening water treatment equipment, desalted water equipment, etc. It is also suitable for valveless filter tank, stirring barrel bottom filter screen and other use scenarios.

[0003] However, the existing water distribution device is usually composed of multiple cylindrical screen pipes. Due to the lack of flow planning, the flow distribution of the water distribution device is uneven in different areas, so that some water distribution devices can normally operate during filtration, but cause large pressure difference in some areas during backwashing, thereby causing damage to the water distribution device.

[0031] Combination Figure 1 As shown in the embodiments of this disclosure, a water distribution method for a filter is provided, applied to a filter, and the method includes:

[0032] Step S101: Obtain the water inlet location of the filter;

[0033] Step S102: Construct a screen tube loop with the water inlet position as the central symmetrical point;

[0034] Among them, the sieve tube loop is composed of multiple loop segments with the same shape;

[0035] Step S103: Connect the water inlet positions to the dividing points between adjacent loop segments through the screen pipe passage, and construct a water distribution device based on the screen pipe loop and the screen pipe passage.

[0036] Step S104: The water to be treated is introduced into the water distribution device from the water inlet, so that the water to be treated is filtered through the slits of the screen tube set on the water distribution device.

[0037] The filter water distribution method provided in this disclosure constructs a screen tube loop with the filter inlet as the central symmetrical point. The screen tube loop consists of loop segments with identical shapes. Screen tube passages connecting the inlet are established based on the dividing points between adjacent loop segments. The water to be treated is then filtered through the water distribution device constructed from the screen tube loop and the screen tube passages. This achieves two advantages: First, because the screen tube loop is constructed with the filter inlet as the central symmetrical point, the dividing points between adjacent loop segments establish screen tube passages connecting the inlet, and the lengths of the screen tube passages are all equal, resulting in a uniform pressure distribution from the screen tube slits to the inlet. Second, because the screen tube loop consists of loop segments with identical shapes, the pressure from the screen tube slits to the inlet is evenly distributed, and the pressure at the screen tube connections is evenly distributed across the screen tube loop and the screen tube passages. This two-pronged approach diverts the water to be treated, achieving a uniform flow distribution to the water distribution device and preventing damage to the filter and the water distribution device.

[0038] Optionally, the water inlet position of the filter is obtained by: if the filter has one water inlet, obtaining the water inlet coordinate of the water inlet and taking the water inlet coordinate as the water inlet position of the filter; if the filter has multiple water inlets, obtaining the water inlet pressure corresponding to each water inlet and the water inlet coordinate corresponding to each water inlet; constructing a reference graph according to the water inlet coordinates, and determining a reference point within the reference graph, wherein each water inlet coordinate is located on the edge of the reference graph; determining the coordinate distance between the reference point and the water inlets according to the reference point coordinate corresponding to the reference point and the water inlet coordinate corresponding to the water inlets, and calculating the pressure reference value corresponding to the water inlets according to the coordinate distance corresponding to the water inlets and the water inlet pressure corresponding to the water inlets, wherein the pressure reference value and the coordinate distance are negatively correlated, and the pressure reference value and the water inlet pressure are positively correlated; solving the reference point coordinate corresponding to the reference point according to the pressure reference value corresponding to each water inlet, so that each pressure reference value is equal; and determining the reference point coordinate obtained by solving as the water inlet position of the filter.

[0039] In combination Figure 2 As shown in the figure, the filter has water inlets A, B, C and D; the water inlets A, B, C and D are connected by line segments in sequence, so that each water inlet coordinate is located on the edge of the reference graph to form a reference graph with the smallest area; since the water inlet pressure of the water inlet A is larger, the water inlet A is farther away from the reference point, the water inlet pressures of the water inlets B, C and D are equal, and the distances from the water inlets B, C and D to the reference point are the same, so that the water inlet pressure of the water inlet A is evenly distributed on the connecting pipe between the water inlet A and the reference point, and the water inlet pressures of the water inlets A, B, C and D applied to the reference point are equal; the reference point coordinate is determined as the water inlet position of the filter, and the water inlet pressure of the filter is evenly distributed.

[0040] In some embodiments, if the pressure reference values corresponding to the water inlets cannot be equal, the water inlet pressures of the water inlets are adjusted so that the pressure reference values corresponding to the water inlets are equal.

[0044] In some embodiments, during the backwashing of the water distribution device, the gas or liquid enters the screen pipe passage and the screen pipe loop through the screen pipe slit, and then converges at the water inlet position X to flow out of the filter, so that the water volume of backwashing is uniformly distributed in the entire water distribution device, thereby avoiding damage to the screen pipe due to a large pressure difference caused by different flow rates.

[0045] Optionally, the method further comprises that the screen pipe diameter of the screen pipe loop is smaller than the screen pipe diameter of the screen pipe passage.

[0046] In some embodiments, the screen pipe passage EX, the screen pipe passage FX, the screen pipe passage GX and the screen pipe passage HX are 1-2 specifications larger than the screen pipe diameters of the loop segment AB, the loop segment BC, the loop segment CD and the loop segment AD, so that the flow capacity of the screen pipe passage EX, the screen pipe passage FX, the screen pipe passage GX and the screen pipe passage HX is larger.

[0047] Optionally, the water inlet position is connected to the segmentation points in the adjacent loop segments through the screen pipe passage, including: if the number of screen pipe loops is one, the water inlet position is connected to the segmentation points in the screen pipe loop through the screen pipe passage; if the number of screen pipe loops is more than one, the screen pipe loops are sequentially sorted from inside to outside, and any screen pipe loop is determined as a target loop; if the target loop is in the first order among the screen pipe loops, the water inlet position is connected to the segmentation points in the target loop through the screen pipe passage; if the target loop is after the first order among the screen pipe loops, a screen pipe loop in the first order before the target loop is determined as a reference loop, the water inlet position is connected to the segmentation points in the target loop according to the auxiliary line, and the screen pipe passage is arranged along the auxiliary line between the target loop and the reference loop.

[0048] In combination Figure 4 As shown in FIG. 1, the water inlet position is taken as a center of symmetry, and the screen pipe loop a and the screen pipe loop b are sequentially constructed in the Cartesian coordinate system from inside to outside, wherein the screen pipe loop a is circular, and the screen pipe loop b is square; the segmentation points are arranged in the screen pipe loop a, the screen pipe loop a is evenly divided into four 90° circular arcs through the segmentation points of the screen pipe loop a, and the points of the screen pipe loop b on the X axis and the Y axis of the Cartesian coordinate system are taken as the segmentation points of the screen pipe loop b; the segmentation points of the screen pipe loop a are connected to the water inlet position through the screen pipe passage c; the segmentation points of the screen pipe loop b are connected to the water inlet position according to the reference line, and the screen pipe loop b is connected to the screen pipe loop a through the screen pipe passage d; the screen pipe loop a, the screen pipe loop b, the screen pipe passage c and the screen pipe passage d construct the water distribution device.

[0049] In this way, the water to be treated is evenly distributed through the multi-stage screen pipe loop for multiple times, so as to reduce the flow rate of the water flow and achieve the purpose of uniform water distribution.

[0050] Optionally, after the water to be treated is filtered through the screen pipe slit arranged on the water distribution device, the method further includes: in response to a backwashing instruction, the filtered water to be treated is transported to the water inlet position through the screen pipe slit, and the water to be treated is output through the water inlet position to backwash the water distribution device.
