Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, and specifically to an expanded granular sludge bed for purifying alcohol waste liquid with optimized purification effect. Background Art

[0002] The expanded granular sludge bed, abbreviated as EGSB, is an improved reactor developed on the basis of the UASB reactor. It is widely used in the treatment of various sewage and sludge. Its greatest advantage is that the incoming sewage and sludge will be in full contact with the internal microorganisms, thus greatly improving the treatment efficiency and optimizing the treatment effect.

[0003] Treating alcohol waste liquid with an expanded granular sludge bed has been a development trend in recent years. Alcohol waste liquid is a highly concentrated organic wastewater containing a large amount of suspended matter and flocculants. To optimize the purification effect of alcohol waste liquid, it is often necessary to use an expanded granular sludge bed to recycle the alcohol waste liquid.

[0004] However, in the process of treating alcohol waste liquid with the existing expanded granular sludge bed, there is often a situation where the liquid enters unevenly, resulting in a low purity of the treated liquid. In addition, after long-term use, sludge will accumulate in the dead corners of the expanded granular sludge bed, which will also affect the purity of the treated liquid. Content of the Utility Model

[0005] The purpose of the utility model is to provide an expanded granular sludge bed for purifying alcohol waste liquid with optimized purification effect, which is used to overcome the above-mentioned defects in the prior art.

[0006] An expanded granular sludge bed for purifying alcohol waste liquid with optimized purification effect according to the utility model includes a tank body, a liquid inlet pipe and a liquid discharge pipe. A cyclone gas-liquid separator is fixedly installed on the tank body, and an exhaust pipe is installed on the cyclone gas-liquid separator. A water distributor is fixedly installed at the bottom inside the tank body, and the water distributor is fixedly communicated with the liquid inlet pipe. A first three-phase separator and a second three-phase separator are fixedly installed in sequence inside the tank body;

[0007] A dispersion component is installed on the top of the water distributor. The dispersion component includes a support plate fixed on the inner wall of the tank body, and at least one vortex fan is rotatably installed on the support plate. The rotation of the vortex fan can make the alcohol waste liquid disperse more evenly.

[0008] Preferably, the fan blades of the vortex fan are made into an arc shape to enhance its dispersion effect on the alcohol waste liquid.

[0009] Preferably, the support plate is of a hollow structure.

[0010] Preferably, a circulation component is installed on the tank body. The circulation component includes a pump fixedly communicated with one end of the drain pipe. The other end of the pump is fixedly communicated with a connecting pipe. The connecting pipe is fixedly connected to a multi-way valve. A water return pipe is fixedly communicated with the tank body. The water return pipe is fixedly communicated with the multi-way valve.

[0011] Preferably, at least one spray pipe is fixedly installed in the tank body, and a plurality of spray heads are evenly and fixedly installed on the spray pipe.

[0012] Preferably, the spray heads are arranged obliquely inwards.

[0013] Preferably, a water return pipe extending to the outside is fixedly communicated with each spray pipe. A connector with the same number as the water return pipe is fixedly communicated with the multi-way valve. The water return pipe and the corresponding connector are fixedly communicated through a hose.

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

[0015] 1. A dispersion component is installed on the top of the water distributor. At least one vortex fan is rotatably installed on the support plate of the dispersion component. After the alcohol waste liquid enters from the liquid inlet pipe, it is dispersed and discharged through the water distributor. When the alcohol waste liquid impacts the vortex fan, it will drive the vortex fan to rotate, making the alcohol waste liquid more evenly dispersed, thereby improving the product purity.

[0016] 2. At least one spray pipe is fixedly installed in the tank body, and a plurality of spray heads are evenly and fixedly installed on the spray pipe. Spraying the liquid through each spray head can effectively prevent the silt from precipitating in the tank body, thereby improving the product purity. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0024] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe an expanded granular sludge bed for purifying alcohol waste liquid with an optimized purification effect of the present utility model or several specific implementation manners, and does not strictly limit the specific protection scope claimed by the present utility model. As used herein, the terms up and down and left and right do not limit their strict geometric definitions, but include tolerances for machining or human errors that are reasonable and inconsistent. The specific features of the expanded granular sludge bed for purifying alcohol waste liquid with an optimized purification effect will be described in detail below:

[0025] Refer to Figures 1-6 , an expanded granular sludge bed for purifying alcohol waste liquid with an optimized purification effect according to an embodiment of the present utility model, includes a tank body 10, a liquid inlet pipe 11 and a liquid discharge pipe 13. A cyclone gas-liquid separator 24 is fixedly installed on the tank body 10, and an exhaust pipe 25 is installed on the cyclone gas-liquid separator 24. A water distributor 19 is fixedly installed at the bottom inside the tank body 10. The water distributor 19 is fixedly communicated with the liquid inlet pipe 11. A first three-phase separator 17 and a second three-phase separator 18 are fixedly installed in sequence inside the tank body 10. This is a conventional structure of a collision granular sludge bed, and basic alcohol waste liquid treatment is realized through the above structure.

[0026] Between the water distributor 19 and the first three-phase separator 17 is a fluidized bed reaction chamber, and between the first three-phase separator 17 and the second three-phase separator 18 is a deep purification reaction chamber.

[0027] However, in the fluidized bed reaction chamber, the input process of the alcohol waste liquid by the water distributor 19 is often not uniform enough, resulting in uneven contact between the alcohol waste liquid and microorganisms, thus affecting the product purity.

[0028] Based on the above problems, a dispersion assembly is installed on the top of the water distributor 19. The dispersion assembly includes a support plate 22 fixed on the inner wall of the tank body 10. At least one vortex fan 23 is rotatably installed on the support plate 22. After the alcohol waste liquid enters from the liquid inlet pipe 11, it is dispersed and discharged through the water distributor 19. When the alcohol waste liquid impacts the vortex fan 23, it will drive the vortex fan 23 to rotate, and the rotation of the vortex fan 23 can make the alcohol waste liquid more evenly dispersed.

[0029] Further, the fan blades of the fan 23 are made into an arc shape to enhance the dispersion effect on the alcohol waste liquid.

[0030] In addition, in order to minimize the influence of the support plate 22 on the flow of the alcohol waste liquid as much as possible, the support plate 22 is made into a hollow structure.

[0031] Single treatment cannot process the alcohol waste liquid to the desired state. Therefore, a circulation component is installed on the tank body 10. The circulation component includes a pump 14 fixedly communicated with one end of the drain pipe 13. The other end of the pump 14 is fixedly communicated with a connecting pipe 15, and the connecting pipe 15 is fixedly connected to a multi-way valve 16;

[0032] Further, a water return pipe 12 is fixedly communicated with the tank body 10, and the water return pipe 12 is fixedly communicated with the multi-way valve 16 to realize the liquid reflux.

[0033] In addition, during the long-term use of the expanded granular sludge bed, there will be a problem of silt precipitation at the edge dead angle position. To solve this problem, at least one spray pipe 20 is fixedly installed in the tank body 10.

[0034] Further, a plurality of spray heads 21 are uniformly and fixedly installed on the spray pipe 20. The liquid sprayed through each spray head 21 can effectively prevent the silt precipitation in the tank body 10, thereby ensuring the product quality.

[0035] Further, the spray heads 21 are arranged obliquely inward, which is beneficial to preventing silt precipitation.

[0036] Preferably, the refluxed alcohol waste liquid is used as the liquid sprayed by the spray heads 21. Specifically, a water return pipe 12 extending to the outside is fixedly communicated with each spray pipe 20. A connecting head 26 with the same number as the water return pipe 12 is fixedly communicated with the multi-way valve 16. The water return pipe 12 and the corresponding connecting head 26 are fixedly communicated through a hose (not shown in the figure, but this part of the content is conventional technology. How the hose is installed and what connection method is used are all conventional technologies in this field).

[0037] Those skilled in the art can clearly understand that various modifications can be made to the above embodiments without departing from the general spirit and concept of the present invention. They all fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
