[0021] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0022] like Figure 1 and Figure 2 As shown, the present invention provides an anaerobic reactor for brewing wastewater, comprising: a shell 1, which is cylindrical, and a water inlet pipe 14 is connected to the lower part of the shell 1; a water distribution device, which is arranged at the lower part of the shell 1, and the water distribution device comprises an annular water pipe 13 and a plurality of water inlet nozzles, the annular water inlet pipe 14 is arranged at the lower part of the shell 1, and is coaxially arranged with the shell 1, the annular water pipe 13 is communicated with the water inlet pipe 14, the plurality of water inlet nozzles are arranged on the annular water pipe 13 and are communicated with the annular water pipe 13, the water inlet nozzle is arranged upwardly inclined relative to the vertical direction, and the water outlet directions of the plurality of water inlet nozzles converge on the central axis of the annular water pipe 13; a lower stirring device, which is arranged at the lower part of the shell 1, and the lower stirring device comprises a shaft rod 9, a plurality of first stirring blades and a stirring motor, The shaft 9 is rotatably connected to the bottom end of the shell 1, the shaft 9 is located inside the shell 1, and the lower end of the shaft 9 extends to the outside of the shell 1. The stirring motor is arranged outside the shell 1 and connected to the shaft 9 to drive the shaft 9 to rotate relative to the shell 1. The multiple first stirring blades are arranged on the upper part of the shaft 9, and the first stirring blades include a baffle 7 and a stirring sheet 6. The plate surface of the stirring sheet 6 is vertically arranged, and the plate surface of the baffle 7 is perpendicular to the vertical plane. One end of the baffle 7 is connected to the shaft 9, and the other end of the baffle 7 is connected to one end of the stirring sheet 6. The length direction of the stirring sheet 6 is parallel to the horizontal direction. The shaft 9 passes through the annular water pipe 13, and the multiple first stirring blades are located above the annular water pipe 13.

[0023] When treating brewery wastewater, the brewery wastewater is first sent into the reactor through the water inlet pipe 14, and then flows into the annular water pipe 13 through the water inlet pipe 14, and then sprayed out through the water inlet nozzle of the annular water pipe 13. The stirring motor of the lower stirring device works, driving the shaft 9 to rotate, and then driving the multiple first stirring blades to rotate. Since the water outlet direction of the water inlet nozzle of the annular water pipe 13 points to the central axis of the annular water pipe 13, the sprayed brewery wastewater flow will be blocked by the baffle 7 of the rotating first stirring blade, and then reflected and dispersed, and dispersed at the bottom of the entire reactor. At the same time, the stirring blade 6 of the first stirring blade stirs the brewery wastewater. Under the blocking of the baffle 7 and the stirring of the stirring blade 6, the brewery wastewater can be evenly dispersed at the bottom of the reactor, so that it can fully contact and react with the microorganisms, and finally improve the efficiency and quality of the anaerobic reaction of the brewery wastewater. As brewing wastewater is continuously input into the reactor, the brewing wastewater at the bottom of the reactor flows upward, is filtered by the filtering device 3, and further reacts with microorganisms in the middle of the reactor, and then is processed by the three-phase separator 2. The biogas is collected in the biogas tank, and the wastewater is discharged into the wastewater tank.

[0024] In a preferred embodiment, in the brewing wastewater anaerobic reactor, the multiple water inlets include a first group of water inlets and a second group of water inlets, wherein the first group of water inlets includes a plurality of first water inlets 12, the second group of water inlets includes a plurality of second water inlets 15, and the inclination angle of the first group of water inlets relative to the vertical direction is greater than the inclination angle of the second group of water inlets relative to the vertical direction.

[0025] The present invention divides a plurality of water inlets into two groups, and the inclination angles of the two groups of water inlets are different, so that the brewing wastewater sprayed from the two groups of water inlets have different directions. When the water flows in two directions collide with the baffle 7, the directions of reflection and dispersion will also be different. This will promote the brewing wastewater to be further evenly dispersed, and fully contact and react with the microorganisms.

[0026] In a preferred embodiment, in the brewing wastewater anaerobic reactor, the angles formed between the water outlet directions of the first water inlet nozzle 12 and the second water inlet nozzle 15 and the plate surface of the baffle plate 7 are both greater than 90 degrees.

[0027] When the water outlet direction is 90 degrees to the plate surface of the baffle 7, the brewing wastewater flow may flow along the original direction when it is blocked and reflected by the baffle 7, which will affect the distribution efficiency of the brewing wastewater. When the water outlet direction is greater than 90 degrees to the plate surface of the baffle 7, the brewing wastewater flow will flow in a direction different from the original direction after reflection, thereby improving the dispersion effect of the brewing wastewater flow at the bottom of the reactor.

[0028] In a preferred embodiment, in the brewing wastewater anaerobic reactor, the lower stirring device also includes a plurality of second stirring blades 10, and the plurality of second stirring blades 10 are arranged at the lower part of the shaft 9, the plate surface of the second stirring blades 10 is vertically arranged, and the upper edge and the lower edge of the second stirring blades 10 are both wavy.

[0029] Another set of second stirring blades 10 is provided in the lower stirring device, and the second stirring blades 10 stir the brewing wastewater below the water distribution device to prevent the brewing wastewater from settling below the water distribution device. The upper and lower edges of the second stirring blades 10 are arranged in a wave shape, which can further increase the disturbance of the brewing wastewater and promote the brewing wastewater below the water distribution device to flow upward.

[0030] In a preferred embodiment, in the anaerobic reactor for brewing wastewater, the lower stirring device includes a plurality of first scraper blades 5 and a plurality of second scraper blades 8, and the plurality of first scraper blades 5 and the plurality of second scraper blades 8 are connected to the shaft 9, the plurality of first scraper blades 5 are arranged above the annular water pipe 13, and the plurality of second scraper blades 8 are arranged below the annular water pipe 13, the outer edge of the first scraper blade 5 is in contact with the inner wall of the shell 1, and the outer edge of the second scraper blade 8 is in contact with the inner wall of the shell 1.

[0031] Brewing wastewater contains a large amount of solid particle impurities. In order to prevent these solid particle impurities from settling downward and adhering to the inner wall of the lower part of the shell 1, the lower stirring device also has a first scraper 5 and a second scraper 8. The first scraper 5 is arranged on the upper part of the annular water pipe 13, and can clean the solid particle impurities attached to the inner wall of the shell 1 and located above the annular water pipe 13. The second scraper 8 is arranged below the annular water pipe 13, and can clean the solid particle impurities attached to the inner wall of the shell 1 and located below the annular water pipe 13.

[0032] In a preferred embodiment, in the brewing wastewater anaerobic reactor, the lower edge of the first scraper 5 abuts against the upper surface of the annular water pipe 13 , and the upper edge of the second scraper 8 abuts against the lower surface of the annular water pipe 13 .

[0033] Based on the above arrangement, the first scraper 5 and the second scraper 8 can clean the interior of the lower part of the shell 1 to prevent solid particle impurities from adhering to the inner wall of the shell 1 and affecting the treatment efficiency of brewing wastewater.

[0034] In a preferred embodiment, in the anaerobic reactor for brewing wastewater, the inner edge of the first scraper blade 5 is connected to one end of the first scraper blade 5 connecting rod 4, the other end of the first scraper blade 5 connecting rod 4 is connected to the shaft rod 9, and the first scraper blade 5 connecting rod 4 is arranged above the first stirring blade; the inner edge of the second scraper blade 8 is connected to one end of the second scraper blade 8 connecting rod, the other end of the second scraper blade 8 connecting rod is connected to the shaft rod 9, and the second scraper blade 8 connecting rod is arranged below the second stirring blade 10.
