Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology in the brewing industry, and particularly relates to brewing wastewater treatment equipment. Background Technology

[0002] During the production process of a winery, a large amount of wastewater is generated. Statistics show that producing 1 ton of 53% vol baijiu (Chinese liquor) consumes approximately 24 tons of water and generates 20 tons of brewing wastewater. This wastewater contains a large amount of organic matter, inorganic matter, microorganisms, and nutrients. The main pollutant is organic matter, and direct discharge would cause serious eutrophication. The decomposition of organic matter requires a large number of aerobic microorganisms. However, existing wastewater treatment equipment is mostly tank-type, with an internal stirring shaft continuously agitating and supplying oxygen. Such equipment occupies a large area, has a low wastewater treatment capacity, and insufficient oxygen intake in the central wastewater section, resulting in uneven oxygen supply, insufficient contact between wastewater and oxygen, and relatively low oxygen uptake by aerobic microorganisms. This leads to low decomposition efficiency of organic matter and long purification times. Summary of the Invention

[0003] The present invention aims to provide a brewing wastewater treatment device to solve the problems of insufficient oxygen intake and uneven oxygen supply in existing wastewater treatment devices.

[0004] The brewing wastewater treatment equipment in this solution includes a wastewater tank with an inlet and an outlet at the top and bottom, respectively. It also includes a circulation pipeline, an oxygen pipeline, and several fan-shaped wastewater channels. The oxygen pipeline is vertically connected to the middle of the wastewater tank. The several wastewater channels wind around inside the wastewater tank from the top to the bottom. The inner side of the wastewater channels is connected to the outer wall of the oxygen pipeline, and the outer side of the wastewater channels is connected to the inner wall of the wastewater tank. The wastewater channels are inclined.

[0005] A turbulence shaft is provided above the wastewater flow channel, which rotates under the action of wastewater flow; the oxygen pipeline is used to introduce oxygen into the space between adjacent wastewater flow channels; a water pump is provided at the bottom of the wastewater tank, and a circulation pipeline connects the water pump and the top of the wastewater tank.

[0006] The working principle of this scheme is as follows: multiple wastewater channels are arranged in a spiral pattern from top to bottom. Wastewater flows downwards from the highest channel, and the impact force of the water flow when passing through the turbulence shaft causes the shaft to rotate, resulting in a certain degree of turbulence and increasing the contact area between the water and air. Simultaneously, oxygen is introduced into the space between the wastewater channels through oxygen pipes, improving the uniformity of oxygen content in the upper, middle, and lower parts of the wastewater tank, and increasing the amount of oxygen within the space. With the increased water flow area, more oxygen comes into contact with the wastewater, thus increasing its oxygen content.

[0007] When the wastewater flows to the bottom of the wastewater tank, it is pumped to the top of the tank by a water pump. The wastewater then circulates in the wastewater pipe for multiple rounds of purification treatment, thereby improving the degree of purification.

[0008] The beneficial technical effects of this invention are: 1. The wastewater flow channel is arranged in a spiral pattern, which increases the flow path of the wastewater, increases the wastewater treatment capacity, and prolongs the wastewater flow time, thereby increasing the oxygen content of the wastewater and providing more oxygen for aerobic microorganisms, which is beneficial to the purification and treatment of wastewater.

[0009] 2. During the flow of wastewater, the impact force of the water flow causes the turbulence shaft to rotate. The rotation of the turbulence shaft causes the water flow to tumble. The tumbling water flow increases the contact area with oxygen, allowing more oxygen to be incorporated.

[0010] 3. The multiple wastewater flow channels are arranged in a swirling pattern to divide the wastewater tank into several smaller spaces. Each space receives a nearly uniform amount of oxygen, resulting in a uniform oxygen content throughout the wastewater tank. This promotes the continuous availability of sufficient oxygen for aerobic microorganisms to thrive, enabling them to decompose organic matter more efficiently and improving wastewater treatment efficiency.

[0011] 4. This solution does not require the storage of wastewater in the wastewater tank. The wastewater is treated by circulating it. With the same floor space as existing technologies, the wastewater treatment capacity can be significantly increased.

[0012] Furthermore, the adjacent edges of several of the aforementioned wastewater channels are connected to form a single spiral channel. This spiral channel can be manufactured as a single unit and installed in one step, simplifying the equipment's manufacturing process.

[0013] Furthermore, the surface of the spiral flow channel is evenly distributed with several protruding ridges extending along the width of the spiral flow channel. When the water flows past the protruding ridges, it is slowed down by the ridges and then needs to go over the ridges to continue flowing. This process further prolongs the time the wastewater spends in the wastewater tank, increasing the oxygen contact time and the amount of oxygen.

[0014] Furthermore, the oxygen pipeline is connected to several branch pipes along its length, and each branch pipe has several evenly distributed air diffusers. The branch pipes are located near the lower surface of the spiral flow channel. The branch pipes are arranged in the same manner as the wastewater flow channel within the wastewater tank, resulting in a higher degree of uniformity of oxygen distribution per unit area of ​​the wastewater flow channel.

[0015] Furthermore, gaps are left between the adjacent edges of several wastewater channels, and baffles are installed at the gaps. The baffles connect the adjacent wastewater channels, and an interlayer communicating with an oxygen pipe is provided inside the baffle. Aeration holes communicating with the interlayer are evenly distributed on the side of the baffle facing the fixed axis. Wastewater flows from one wastewater channel to the next, forming a water curtain. The water curtain can contact oxygen on all sides, creating a larger area for contact with more oxygen. Simultaneously, oxygen is introduced through the baffles. The water curtain, being close to the baffles, can more quickly contact the high-density oxygen, promoting an increase in the amount of oxygen incorporated. This is more conducive to the continuous provision of sufficient oxygen for aerobic microorganisms to grow, further improving the efficiency of aerobic microorganisms in decomposing organic matter and increasing wastewater treatment efficiency.

[0016] Furthermore, there are multiple turbulence shafts, which are arranged at equal intervals around the oxygen pipeline from top to bottom. Each turbulence shaft includes a horizontal fixed shaft, on which multiple collars are rotatably connected at intervals, and multiple turbulence plates are connected circumferentially to the collars.

[0017] Furthermore, the edges of adjacent wastewater channels are staggered, and the baffle is connected to the edge of the higher end of the wastewater channel below it. Attached Figure Description

[0020] Figure 3 for Figure 2 Enlarged view of point A in the middle. Detailed Implementation

[0021] The following detailed description illustrates the specific implementation method:

[0022] The reference numerals in the accompanying drawings of the instruction manual include: wastewater tank 1, wastewater channel 2, protruding rib 3, branch pipe 4, fixed axis 5, collar 6, baffle 7, oxygen pipeline 8, circulation pipeline 9, water pump 10, vent hole 11, baffle 12.

[0023] Example 1 is basically as shown in the appendix. Figure 1The image shows a brewing wastewater treatment device, including a wastewater tank 1. The wastewater tank 1 has an inlet and an outlet at its top and bottom, respectively. It also includes a circulation pipe 9, an oxygen pipe 8, and several fan-shaped wastewater channels 2. The oxygen pipe 8 is vertically connected to the middle of the wastewater tank 1. The several wastewater channels 2 wind around the wastewater tank 1 from top to bottom. The inner side of the wastewater channels 2 connects to the outer wall of the oxygen pipe 8, and the outer side of the wastewater channels 2 connects to the inner wall of the wastewater tank 1. The wastewater channels 2 are inclined. The adjacent edges of the wastewater flow channel 2 are connected to form a spiral flow channel. The surface of the spiral flow channel is evenly distributed with several protruding ridges 3 extending along the width direction of the spiral flow channel. A turbulence shaft is provided above the wastewater flow channel 2. The turbulence shaft rotates under the action of wastewater flow. There are multiple turbulence shafts. The multiple turbulence shafts are arranged at equal distances along the oxygen pipeline 8 from top to bottom. The turbulence shaft includes a horizontal fixed shaft 5. Multiple collars 6 are rotatably connected to the fixed shaft 5 at intervals. Multiple turbulence plates 7 are connected to the circumference of the collars 6.

[0024] The oxygen pipeline 8 is connected to several branch pipes 4 along its length. Several air diffusers 11 are evenly distributed on the branch pipes 4. The branch pipes 4 are located near the lower surface of the spiral flow channel and are used to introduce oxygen into the space between the adjacent wastewater flow channels 2. A water pump 10 is provided at the bottom of the wastewater tank 1. The circulation pipeline 9 connects the water pump 10 and the top of the wastewater tank 1.

[0025] In implementing this scheme, wastewater flows downwards from the highest wastewater channel 2 in a spiral motion. Upon passing the turbulence shaft, the impact force of the water flow causes the shaft to rotate, resulting in some turbulence and increasing the contact area between the water and air. Upon passing the convex ridge 3, the wastewater is slowed down by its interception and must then overcome the ridge to continue flowing. This process further prolongs the time the wastewater spends in the wastewater tank 1, increasing the oxygen contact time and oxygen quantity. Simultaneously, the oxygen pipe 8 is connected to an oxygen source, distributing oxygen into the branch pipe 4, ensuring continuous oxygenation in the space between the wastewater channels 2. This improves the uniformity of oxygen content in the upper, middle, and lower spaces within the wastewater tank 1, while also increasing the oxygen quantity within the space. With the increased water flow area, more oxygen is contacted, further increasing the oxygen content in the wastewater.

[0026] When the wastewater flows to the bottom of the wastewater tank 1, it is pumped to the top of the wastewater tank 1 by the action of the water pump 10. The wastewater is then circulated in the wastewater pipe for multiple rounds of purification treatment to improve the degree of purification.

[0027] Example 2 differs from Example 1 in that... Figure 2 , Figure 3As shown: A gap is left between the edges of several adjacent wastewater channels 2. A baffle 12 is installed at the gap, connecting the upper and lower adjacent wastewater channels 2. A cavity connected to an oxygen pipe 8 is provided inside the baffle 12. Ventilation holes 11, connected to the cavity, are evenly distributed on the side of the baffle 12 facing the fixed axis 5. The edges of adjacent wastewater channels 2 are staggered, and the baffle 12 is connected to the edge of the higher end of the wastewater channel 2 below it.
