A high-concentration organic wastewater anaerobic reactor

Abstract

This utility model relates to a high-concentration anaerobic reactor for organic wastewater, comprising a cylindrical body with a drain pipe connected to the bottom and a drainage pipe connected to the top. The top is equipped with an exhaust pipe and a return pipe, and a separator is installed inside. An inlet pipe at the bottom of the cylindrical body connects to an outlet pipe, and a guide pipe is provided on the outer periphery of the outlet pipe. A float is installed at the upper end, and a spiral blade is installed inside. The inlet pipe and outlet pipe are slidably fitted together, with the upper corrugated ring contacting the protruding ends of the lower corrugated ring. The liquid impacts the spiral blade, causing the outlet pipe to rotate. The guide pipe's orientation enhances the rotation effect, ensuring full contact between the liquid and sludge. Simultaneously, the water flow impact and buoyancy cause the corrugated ring to make intermittent contact, and the outlet pipe drives the guide pipe to stir, further promoting the sludge reaction. This utility model effectively improves reaction efficiency and quality through the rotating spray and up-and-down vibration of the outlet pipe, meeting the requirements for sludge treatment.

Description

Technical Field

[0001] This utility model relates to the field of anaerobic reactors, specifically to an anaerobic reactor for high-concentration organic wastewater. Background Technology

[0002] The technical field involved in this utility model patent is sludge treatment equipment. In the sludge treatment process, ensuring sufficient contact between the liquid and sludge to improve reaction efficiency and quality is a crucial step, and the design and improvement of related equipment are of great significance for optimizing sludge treatment results.

[0003] In existing sludge treatment equipment, achieving sufficient contact between liquid and sludge is often difficult. Some devices fail to effectively create a smooth flow pattern during liquid transport, resulting in uneven mixing of the liquid and sludge and affecting reaction efficiency. Furthermore, most existing structures lack effective stirring mechanisms, failing to further promote the reaction between sludge and liquid, making it difficult to achieve ideal sludge treatment quality and meet increasingly stringent requirements. Therefore, those skilled in the art have provided a high-concentration organic wastewater anaerobic reactor to address the problems mentioned in the background section. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a high-concentration anaerobic reactor for organic wastewater. Through the rotating spray and vertical vibration of the effluent pipe, this invention solves the problem that existing equipment cannot effectively drive the liquid to form a good flow state during liquid transportation, resulting in uneven mixing of liquid and sludge, which affects reaction efficiency. Furthermore, most existing structures lack an effective stirring mechanism, which cannot further promote the reaction between sludge and liquid, making it difficult to achieve the desired sludge treatment quality and meet the increasingly demanding requirements for sludge treatment.

[0005] The objective of this utility model is achieved through the following means:

[0006] An anaerobic reactor for high-concentration organic wastewater includes a cylindrical body. A sewage pipe is connected to one side of the bottom of the cylindrical body, and a drain pipe is connected to one side of the top of the cylindrical body. An exhaust pipe is installed at the top of the cylindrical body, and a return pipe is installed on one side of the exhaust pipe. A separator is installed inside the cylindrical body. An inlet pipe is connected to the bottom of the cylindrical body, and an outlet pipe is installed at the end of the inlet pipe inside the cylindrical body. A guide pipe is connected to the outer circumference of the outlet pipe, and a float is installed at the upper end of the outlet pipe. An upper corrugated ring is installed on the outer wall of the end of the inlet pipe, and a lower corrugated ring is installed on the inner wall of the end of the outlet pipe. A spiral blade is installed inside the outlet pipe.

[0007] Furthermore, the inlet pipe and the outlet pipe are slidably connected, and the protruding ends of the upper corrugated ring and the lower corrugated ring are in contact with each other.

[0008] Furthermore, the float has a hollow structure, is made of corrosion-resistant material, and is spherical. Under the force of the float, the water outlet pipe floats upward, causing the lower corrugated ring to contact the upper corrugated ring.

[0009] Furthermore, the guide pipes are arranged in a ring array around the outer wall of the outlet pipe, and the guide pipes are inclined. The spiral blades are fixed inside the outlet pipe by welding. The spiral blades rotate in the same direction as the guide pipes. Through the impact of the liquid, the spiral blades can drive the outlet pipe to rotate. Moreover, the rotation effect of the outlet pipe is further increased as the guide pipes are oriented. While the rotation of the outlet pipe makes the liquid and sludge come into more full contact, due to the impact of the water flow and the buoyancy of the float, the upper corrugated pipe and the lower corrugated pipe make intermittent contact, so that the guide pipes driven by the outlet pipe play a stirring role.

[0010] The beneficial effects of this invention are as follows: The float provides upward buoyancy to the outlet pipe. Combined with the design of the upper and lower corrugated rings contacting each other, after the outlet pipe floats to a suitable position, when liquid is introduced into the outlet pipe through the inlet pipe, the liquid passes through the spiral blades and exits from the end of the guide pipe. The spiral blades drive the outlet pipe to rotate, and the orientation of the guide pipe further enhances the rotation effect, allowing the liquid and sludge to come into more complete contact, thus improving reaction efficiency. Simultaneously, under the impact of the water flow and the buoyancy, the upper and lower corrugated rings make intermittent contact, causing the outlet pipe to drive the guide pipe to achieve a stirring effect, further promoting sludge reaction and effectively improving the quality and efficiency of sludge treatment.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] In this embodiment, refer to Figures 1-3 The specific implementation of the high-concentration organic wastewater anaerobic reactor includes a cylindrical body 1. A sewage pipe 11 is connected to one side of the bottom end of the cylindrical body 1, a drain pipe 10 is connected to one side of the top end of the cylindrical body 1, an exhaust pipe 8 is provided at the top of the cylindrical body 1, a return pipe 9 is provided on one side of the exhaust pipe 8, a separator 7 is provided inside the cylindrical body 1, an inlet pipe 2 is connected to the bottom of the cylindrical body 1, an outlet pipe 3 is provided at one end of the inlet pipe 2 inside the cylindrical body 1, a guide pipe 5 is connected to the outer periphery of the outlet pipe 3, a float 6 is installed at the upper end of the outlet pipe 3, an upper corrugated ring 201 is installed on the outer wall of the end of the inlet pipe 2, a lower corrugated ring 301 is installed on the inner wall of the end of the outlet pipe 3, a spiral blade 4 is installed inside the outlet pipe 3, the inlet pipe 2 and the outlet pipe 3 are slidably sleeved together, and the protruding ends of the upper corrugated ring 201 and the lower corrugated ring 301 are in contact with each other.

[0017] The float 6 is a hollow structure made of corrosion-resistant material and is spherical. Under the force of the float 6, the outlet pipe 3 floats upward, causing the lower corrugated ring 301 to contact the upper corrugated ring 201. The guide pipes 5 are arranged in a ring array on the outer periphery of the outlet pipe 3. The guide pipes 5 are inclined. The spiral blade 4 is fixed inside the outlet pipe 3 by welding. The spiral blade 4 and the guide pipe 5 rotate in the same direction. Through the impact of the liquid, the spiral blade 4 can drive the outlet pipe 3 to rotate. Furthermore, the rotation effect of the outlet pipe 3 is further increased as the guide pipe 5 is oriented. While the outlet pipe 3 rotates, the liquid and sludge come into more complete contact. Due to the impact of the water flow and the buoyancy of the float 6, the upper corrugated pipe and the lower corrugated pipe make intermittent contact, thereby making the guide pipe 5 driven by the outlet pipe 3 play a stirring effect.

[0018] This practical anaerobic reactor for organic wastewater includes a cylindrical body 1, an inlet pipe 2, and an outlet pipe 3. A sewage pipe 11 is connected to one side of the bottom of the cylindrical body 1 for sludge discharge, and a drain pipe 10 is connected to one side of the top of the cylindrical body 1 for the discharge of filtered liquid. An exhaust pipe 8 is installed at the top of the cylindrical body 1 for biogas discharge, and a return pipe 9 is installed on one side of the exhaust pipe 8 for the return of liquid separated from biogas. Two sets of separators 7 are also installed inside the cylindrical body 1 for liquid filtration.

[0019] A water outlet pipe 3 is sleeved on one end of the liquid inlet pipe 2 at the bottom of the cylinder 1, which is inside the cylinder 1. An inclined guide pipe 5 is connected to the outer circumference of the water outlet pipe 3, and a float 6 is installed at the upper end of the water outlet pipe 3. The float 6 can provide buoyancy to make the water outlet pipe 3 rise. In the end of the water outlet pipe 3 that is sleeved with the liquid inlet pipe 2, an upper corrugated ring 201 is installed on the outer wall of the end of the liquid inlet pipe 2, and a lower corrugated ring 301 is installed on the inner wall of the end of the water outlet pipe 3. The protruding ends of the upper corrugated ring 201 and the lower corrugated ring 301 are in contact with each other. A spiral blade 4 is installed inside the water outlet pipe 3.

[0020] Under the force of the float 6, the outlet pipe 3 floats upward, causing the lower corrugated ring 301 to contact the upper corrugated ring 201. As the inlet pipe 2 inputs liquid into the outlet pipe 3, the liquid passes through the spiral blade 4 and is discharged from the end of the guide pipe 5. Through the impact of the liquid, the spiral blade 4 can drive the outlet pipe 3 to rotate. Furthermore, as the guide pipe 5 is oriented, the rotation effect of the outlet pipe 3 is further increased. While the rotation of the outlet pipe 3 makes the liquid and sludge come into more full contact, due to the impact of the water flow and the buoyancy of the float 6, the upper and lower corrugated pipes make intermittent contact, thereby making the guide pipe 5 driven by the outlet pipe 3 play a stirring effect, further reacting the sludge.

[0021] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
