Description

Technical Field

[0001] The utility model relates to the technical field of tubular microporous aeration in an aerobic pool in wastewater treatment, in particular to a tubular microporous aeration membrane installation structure. Background Art

[0002] In current wastewater treatment, the mainstream aerobic pool aeration methods are divided into two types: disc microporous aerator aeration and tube microporous aerator aeration. The disc microporous aerator is mainly an aeration blower that blows compressed air through the rubber micropores covered on the ABS disc to achieve the purpose of aeration; the tube microporous aerator uses a blower to let the compressed air enter through one end of the ABS pipe of the DN65 pipe, and then exhausts from the pipe surface at 5cm inside the pipe. After the microporous aeration membrane is covered on the surface of the aeration membrane tube, the gas is blown out from the aeration membrane to achieve the purpose of aeration.

[0003] The aeration installation method of the disc microporous aerator is: the aerator is installed at the bottom of the pool by installing a saddle seat on the aeration branch pipe installed at the bottom of the pool. There are many pipes for installation and connection. The aeration of the aerobic pool is operated 24 hours a day. After years of operation, the aeration membrane and pipes will be damaged. At this time, the system needs to be stopped, the pool body needs to be emptied, and manual reinstallation is performed. The maintenance cost is high and it is not easy to operate.

[0004] The installation method of the tubular microporous aerator is: by installing the aerator on a liftable riser, the aeration membrane group is installed on the bottom of the pool through the T-shaped thread at the bottom of the riser. The tubular microporous aeration is to take in air near the end of the riser, and then exhaust air through the microporous aeration membrane on the surface of the membrane tube in the aeration membrane group. Since two DN65 pipe clamps are fixed at both ends of the membrane tube in the tubular microporous aerator, the aeration membrane is in an overall bow shape during normal operation, and the pipe clamps at both ends are under great stress; at the same time, the aeration of the aerobic pool is operated for 24 hours, and the aeration membrane is very easy to be damaged and leaked, resulting in an increase in the frequency of aeration membrane replacement. Although the tubular microporous aerator is liftable, high-frequency aeration membrane replacement is not conducive to the stable operation of the aerobic pool system. Utility Model Content

[0005] The main purpose of the utility model is to provide a tubular microporous aeration membrane installation structure to solve the problem that two pipe clamps are fixed at both ends of the membrane tube of the tubular microporous aerator in the prior art, resulting in the aeration membrane being in a bow shape as a whole during normal operation, causing greater force on the pipe clamps at both ends, and the aeration membrane is very easy to be damaged and leaked.

[0006] In order to solve the above technical problems, the utility model is implemented as follows: a tubular microporous aeration membrane installation structure, comprising: an aeration membrane tube and an aeration membrane, one end of the aeration membrane tube is an air inlet end, and the other end is provided with a pipe plug for blocking the aeration membrane tube; the aeration membrane is sleeved on the outside of the aeration membrane tube; the outer sleeve of the aeration membrane is provided with a plurality of pipe hoops, and the plurality of pipe hoops are arranged in sequence along the length direction of the aeration membrane tube, wherein two pipe hoops are respectively located at the two ends of the aeration membrane;

[0007] A plurality of pipe hoops divide the aeration membrane and the aeration membrane tube into a plurality of equidistant sections along the length direction of the aeration membrane tube, and the aeration membrane tube and the aeration membrane between two adjacent pipe hoops together form a small aeration membrane chamber; a plurality of air outlet holes are arranged on the tube wall of the corresponding aeration membrane tube in each of the small aeration membrane chambers.

[0008] As a further technical solution, the air inlet end of the aeration membrane tube is provided with an air inlet pipe, the interior of the air inlet end of the aeration membrane tube is provided with an internal thread interface, and the air inlet pipe is connected to the aeration membrane tube through the internal thread interface; the air inlet pipe is communicated with the interior of the aeration membrane tube.

[0009] As a further technical solution, the number of the pipe clamps is four; the number of the small aeration membrane chambers is three.

[0010] As a further technical solution, four groups of air outlet holes are provided on the corresponding aeration membrane tube in each of the small aeration membrane chambers, and the air outlet holes are connected to the interior of the aeration membrane tube; each group of air outlet holes includes two air outlet holes, the two air outlet holes in each group are on the same plane, and the two air outlet holes in each group are arranged in sequence along the length direction of the aeration membrane tube; the four groups of air outlet holes are arranged in a cross shape along the circumferential direction of the cross section of the aeration membrane tube.

[0011] As a further technical solution, the two air outlet holes in each group are located in the middle of the aeration membrane tube of the corresponding section.

[0012] As a further technical solution, an interface fixing support is provided between the side of the inner thread interface close to the end of the aeration membrane tube and the air inlet pipe.

[0013] As a further technical solution, the diameter of the air outlet is 58 mm.

[0014] The beneficial effects of the utility model are:

[0015] 1. Compared with the original tubular microporous aerator, the present invention adopts a different method of taking in air from one end and then exhausting it from the surface of the membrane tube, and fixing the two ends of the aeration membrane with pipe hoops. The present application takes in air from one end of the aeration membrane tube and blocks the other end. Instead of blocking the two ends of the membrane tube with the original two pipe hoops, the aeration membrane tube and the aeration membrane are divided into equal parts by four pipe hoops at a fixed distance to form a plurality of small aeration membrane chambers, and air outlet holes are evenly opened on the aeration membrane tube. Each small aeration membrane chamber corresponds to its own air outlet hole. After the compressed air passes through the air outlet hole, it is evenly exposed through the aeration membrane. There are two air outlet holes on the same plane between each two adjacent pipe hoops, that is, there are eight air outlet holes in each small aeration membrane chamber; and the eight air outlet holes are evenly divided into four groups, and the four groups of air outlet holes are arranged in a cross shape in the circumferential direction of the cross section of the aeration membrane tube, that is, the air outlet holes of each adjacent group are supported at 90 degrees.

[0016] 2. The tubular microporous aeration structure of the utility model is simple, and the prior art changes the air outlet of the entire aeration membrane to an evenly divided aeration membrane outlet of multiple sections, shortening the distance between two adjacent pipe clamps, while increasing the aperture and number of the air outlet holes, reducing the air flow rate of the aeration outlet holes, and reducing the pressure at the aeration membrane pipe clamp. The tubular microporous aeration membrane group installation structure provided by the utility model greatly reduces the outlet pressure of the aeration membrane by adding two pipe clamps and air inlet and outlet methods, reduces the frequency of aeration membrane damage and leakage, and under normal working conditions, prolongs the service life of the aeration membrane and the operating cycle of the aerator, increases the stability of the biochemical system operation, and reduces the cost of manual maintenance.
