Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater treatment compressed air conveying device. Background Technology

[0002] Wastewater treatment refers to the process of removing or reducing pollutants in wastewater through physical, chemical, and biological methods to meet discharge standards or reuse requirements. Currently, blowers are used in the wastewater treatment process to supply air to the aeration tank. Usually, wastewater treatment plants will install two blowers next to the aeration tank, with one on and one on standby, to meet the aeration volume of the two biological lines.

[0003] If the quality of the incoming wastewater exceeds expectations, and additional aeration pipes are needed to supply aeration to the integrated equalization tank for neutralization, a single aeration blower may not be able to meet the biochemical requirements. Operating two blowers may result in capacity limitations and may easily cause equipment failure. Therefore, a wastewater treatment compressed air delivery device is proposed. By setting up a first air intake component, compressed air from an air compressor can be delivered to tanks such as the aeration tank and the integrated equalization tank. Furthermore, the compressed air can be dehumidified by the first and second metal baffles inside the tank. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] The first air intake assembly delivers compressed air from the air compressor to the air intake tank, the comprehensive conditioning tank, and other tanks. Furthermore, the compressed air is dehumidified by the first and second metal baffles within the tank. Figure 1-4 As shown, the wastewater treatment compressed air conveying device of this utility model includes a main air supply pipe 1. A first air intake assembly 2 is provided at both ends of one side of the main air supply pipe 1. The first air intake assembly 2 includes a first air intake pipe 201 provided at both ends of one side of the main air supply pipe 1. A first flow meter 203 is sleeved on the outside of the first air intake pipe 201. A first butterfly valve 204 is fixed to one end of the first air intake pipe 201 by a flange. A connecting pipe 202 is provided at one end of the first butterfly valve 204. A barrel 5 is fixed between the connecting pipe 202 and the first butterfly valve 204 by a flange.

[0024] The bottom ends of the barrel 5 are fixed with first metal baffles 9 by bolts. The top of the barrel 5 is fixed with a barrel cover 6 by bolts. The bottom ends of the barrel cover 6 are fixed with second metal baffles 10 by bolts. Electric heating wires 11 are fixed equidistantly inside the first metal baffles 9 and the second metal baffles 10. The interior of the first metal baffles 9 and the second metal baffles 10 located outside the electric heating wires 11 is filled with magnesium oxide powder 12.

[0025] When in use, the compressed air generated by the air compressor is delivered to the main air supply pipe 1 through the first air inlet pipe 201 and the connecting pipe 202. The electric heating wire 11 heats the first metal baffle 9 and the second metal baffle 10, which can dehumidify the compressed air flowing in the barrel 5.

[0026] For example, such as Figure 4 As shown, the present invention also includes a second air intake assembly 3 at one end of the main air supply pipe 1. The second air intake assembly 3 includes a second air intake pipe 301 fixed to one end of the main air supply pipe 1 by a flange. A second flow meter 302 is sleeved on the outside of the second air intake pipe 301. A second butterfly valve 303 is fixed to one end of the second air intake pipe 301 by a flange. A second one-way valve 304 is connected to one end of the second butterfly valve 303 by a threaded groove.

[0027] During use, the gas produced by the blower is delivered to the main gas supply pipe 1 through the second air inlet pipe 301, and the second flow meter 302 is used to detect and display the flow rate of the gas in the second air inlet pipe 301.

[0028] For example, such as Figure 3 As shown, the present invention also includes the first metal baffle 9 and the second metal baffle 10 being arranged alternately, the first metal baffle 9 and the second metal baffle 10 being made of copper material, and the inner side of the barrel body 5 being bonded with a heat insulation layer 13, the heat insulation layer 13 being made of polystyrene foam material.

[0029] When in use, the first metal baffle 9 and the second metal baffle 10, made of copper, have good thermal conductivity, and the insulation layer 13, made of polystyrene foam, has good thermal insulation performance, which can reduce the loss of heat inside the barrel 5.

[0030] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes a thermostat 7 mounted on the top of the cylinder cover 6 via a mounting base. The detection end of the thermostat 7 is located inside the cylinder body 5, and the current output end of the thermostat 7 is electrically connected to the current input end of the electric heating wire 11 via a power cord.

[0031] During use, the heating of the electric heating wire 11 and its heating temperature can be controlled by the thermostat 7.

[0032] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a main butterfly valve 4 fixed at the end of the main gas pipe 1 away from the second air intake assembly 3 via a flange, and a pressure relief valve 8 connected to the top of the cylinder cover 6 located on the side of the thermostat 7 via a threaded groove.

[0033] In use, the main butterfly valve 4 is used to shut off the gas in the main gas pipeline 1, and the pressure relief valve 8 is used to release pressure in the barrel 5.

[0034] For example, such as Figure 2 As shown, the present invention also includes a first one-way valve 205 sleeved on the outside of the connecting pipe 202, and one end of the connecting pipe 202 is connected to one side of the main gas pipeline 1 through a pipe joint.

[0035] When in use, the first one-way valve 205 is designed to prevent gas in the main gas pipeline 1 from flowing into the connecting pipe 202.

[0036] In use, one end of the second air inlet pipe 301 is connected to the air outlet of the blower, one end of the first air inlet pipe 201 is connected to the air outlet of the air compressor, one end of the main air supply pipe 1 is connected to the air inlet pipe of the breathing pool, the integrated regulating pool, etc., using a pipe, and the device is connected to an external power source using a power cord.

[0037] Opening the second butterfly valve 303 allows the gas blown out by the blower to be blown into the main gas pipeline 1 through the second air inlet pipe 301, and then transported to the gas tank, the integrated regulating tank and other tanks. The second flow meter 302 is set to detect and display the gas flow rate in the second air inlet pipe 301. The second one-way valve 304 is set to prevent the gas in the main gas pipeline 1 from flowing back into the second air inlet pipe 301.

[0038] Close the second flow meter 302 and open the first butterfly valve 204 so that the compressed air produced by the two air compressors can flow through the first air inlet pipe 201, the main butterfly valve 4 and the connecting pipe 202 to the main air delivery pipe 1, and then the main air delivery pipe 1 is delivered to the breathing pool, the comprehensive regulating pool and other pools.

[0039] The first flow meter 203 can detect and display the flow rate of compressed air in the first air inlet pipe 201. The first check valve 205 can prevent the gas in the main air supply pipe 1 from flowing back into the connecting pipe 202. The main butterfly valve 4 is used to cut off the gas in the main air supply pipe 1.

[0040] The electric heating wire 11 is controlled by the thermostat 7. The magnesium oxide powder 12 transfers the heat generated by the electric heating wire 11 to the first metal baffle 9 and the second metal baffle 10. When the compressed air enters the barrel 5, it is blocked by the first metal baffle 9 and the second metal baffle 10 in turn, thereby increasing the time that the compressed air stays in the barrel 5. The compressed air is heated and dehumidified by the first metal baffle 9 and the second metal baffle 10.

[0041] The insulation layer 13, made of polystyrene foam, serves to insulate and retain heat, reducing heat loss from the barrel 5. When compressed air dehumidifies inside the barrel 5, it increases the pressure inside the barrel 5. The pressure relief valve 8 can release pressure periodically.
