Description

Technical Field

[0001] This utility model relates to the field of environmental protection treatment technology in leather production, specifically to an integrated co-treatment device for waste gas and wastewater from leather production. Background Technology

[0002] The leather production process generates a large amount of waste gas and wastewater. The waste gas usually contains harmful substances such as dust and volatile organic compounds (VOCs), while the wastewater contains various chemical agents, heavy metal ions, and other pollutants.

[0003] Currently, the treatment of waste gas and wastewater is usually carried out separately. This not only requires the construction of two independent treatment facilities, increasing the land area and investment costs, but also may result in resource waste and incomplete treatment during the process. Utility Model Content

[0004] The purpose of this invention is to provide an integrated co-treatment device for waste gas and wastewater from leather production, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] An integrated co-treatment device for waste gas and wastewater from leather production includes a waste gas treatment mechanism, a wastewater treatment mechanism at the bottom of the waste gas treatment mechanism, and a sedimentation mechanism on the right side of the wastewater treatment mechanism.

[0007] The exhaust gas treatment mechanism includes a tower body, a support block fixedly connected to the top wall of the tower body, multiple annular grooves opened at the bottom of the support block, annular pipes fixedly connected to each of the multiple annular grooves, nozzles fixedly connected to the bottom of the annular pipes, a booster water pump installed at the top of the tower body, an inlet pipe fixedly connected to the top of the booster water pump, a first delivery pipe fixedly connected to the front end of the booster water pump, a diversion pipe fixedly connected to the bottom of the first delivery pipe, an air inlet pipe fixedly connected to the left side of the tower body, a filter screen provided on the inner wall of the tower body, and an exhaust pipe fixedly connected to the bottom of the tower body.

[0008] The wastewater treatment device includes a water storage frame, a connecting pipe fixedly connected to the top of the water storage frame, a wastewater pipe fixedly connected to the rear of the water storage frame, a stirring rod rotatably connected inside the water storage frame, a motor fixedly connected to the left side of the stirring rod, a connecting plate fixedly connected to the right side of the water storage frame, a first water pump fixedly connected to the top of the connecting plate, a suction pipe provided behind the first water pump, a second delivery pipe fixedly connected to the top of the first water pump, a chemical inlet pipe fixedly connected to the top of the water storage frame, and a cover plate snapped onto the top of the chemical inlet pipe.

[0009] Preferably, a support ring is fixedly connected to the outside of the tower body, and multiple support legs are fixedly connected to the bottom of the support ring. The ends of the multiple support legs away from the support ring are all fixedly connected to the top of the water storage frame.

[0010] The tower body is stably fixed to the top of the water storage frame by the support ring and support legs, which ensures the connection stability between the waste gas treatment mechanism and the wastewater treatment mechanism and provides a structural foundation for the stable operation of the entire integrated co-processing device.

[0011] Preferably, multiple nozzles are provided, and the multiple nozzles are respectively located at the bottom of multiple annular tubes and distributed in a circumferential array. Multiple diverter tubes are provided, and the multiple diverter tubes are respectively connected to the top of multiple annular tubes.

[0012] Multiple nozzles arranged in a circular array ensure a wider and more uniform spraying range, which is beneficial for the full treatment of exhaust gas. Multiple diversion pipes are connected to the ring pipe, which can evenly distribute the liquid delivered by the booster pump into each ring pipe, and then spray it out through the nozzles, thereby improving the efficiency and quality of exhaust gas treatment.

[0013] Preferably, the bottom of the discharge pipe is fixedly connected to the top of the connecting pipe via a flange, and flanges are provided on the outside of both the air inlet pipe and the sewage pipe. The motor is fixedly connected to the left side of the water storage frame.

[0014] The flange connection ensures a secure and airtight connection, facilitating installation, disassembly, and maintenance. The motor is fixed to the left side of the water storage frame, clearly defining its installation position and facilitating the connection and drive of the motor to the stirring rod, thus ensuring the normal operation of the wastewater treatment system.

[0015] Preferably, the end of the suction tube furthest from the first water pump is connected to the right side of the water storage frame.

[0016] The function of the suction pipe is clearly defined: it can suck out the sewage in the water storage box and transport it to the sedimentation mechanism through the first water pump and the second conveying pipe, thus ensuring smooth liquid transport between the sewage treatment mechanism and the sedimentation mechanism.

[0017] Preferably, the sedimentation mechanism includes a sedimentation tank, and a third conveying pipe is fixedly connected to the right side of the sedimentation tank, and a switch valve is installed inside the third conveying pipe.

[0018] Preferably, the end of the second delivery pipe furthest from the first water pump is located inside the sedimentation tank.

[0019] The function of the second conveying pipe is clarified: it can transport the sewage treated by the sewage treatment unit to the sedimentation tank, ensuring that the sewage can smoothly enter the sedimentation unit for sedimentation treatment, and realizing the continuity of sewage treatment in the integrated waste gas and sewage co-treatment device.

[0020] This utility model, by adopting the above technical solution, has significant technical effects:

[0021] 1. The waste gas generated during the leather production process is introduced into the tower body through the inlet pipe. The flange on the outside of the inlet pipe facilitates connection with the waste gas conveying pipeline, ensuring that the waste gas enters the tower body smoothly. The booster water pump is started, and water enters the booster water pump through the water inlet pipe. After being pressurized, it is conveyed to the distribution pipe through the first conveying pipe. The distribution pipe distributes the water to each ring pipe, and then sprays it out through the nozzles at the bottom of the ring pipe to form water mist. The water mist comes into full contact with the waste gas in the tower body. Harmful substances in the waste gas, such as dust and some soluble gases, are adsorbed or dissolved by the water mist, thus purifying the waste gas. After being sprayed, the waste gas falls with the water droplets and passes through the filter screen set on the inner wall of the tower body. The filter screen further intercepts the residual particulate matter and other impurities in the waste gas, further purifying the waste gas. The waste liquid generated during the spraying process is discharged through the discharge pipe at the bottom of the tower body. The bottom of the discharge pipe is fixedly connected to the top of the connecting pipe via a flange. Wastewater enters the wastewater treatment unit through the connecting pipe. Wastewater generated during leather production is introduced into the storage frame through a wastewater pipe. The flange on the outside of the wastewater pipe facilitates connection to the wastewater conveying pipe. Simultaneously, wastewater generated by the exhaust gas treatment unit also enters the storage frame through the connecting pipe, achieving mixed treatment of exhaust gas treatment wastewater and leather production wastewater. The cover plate at the top of the inlet pipe is opened, and an appropriate amount of wastewater treatment agents, such as flocculants and neutralizing agents, are added to the storage frame. The motor is started, and it drives the stirring rod to rotate within the storage frame, ensuring thorough mixing and reaction between the wastewater and the agents. This promotes the coagulation, sedimentation, or chemical reaction of pollutants in the wastewater, achieving purification. To treat the wastewater, the first water pump is started. The first water pump sucks out the pre-treated wastewater from the water storage box through the suction pipe, and then transports it to the sedimentation mechanism through the second conveying pipe. The end of the suction pipe away from the first water pump is connected to the right side of the water storage box to ensure smooth extraction of wastewater. The waste liquid generated from the exhaust gas treatment is mixed with the leather production wastewater for treatment, realizing the integrated utilization of resources, reducing the footprint and investment cost of the treatment equipment, and improving the overall treatment efficiency. This device integrates the exhaust gas treatment and wastewater treatment mechanisms, realizing the synergistic treatment of exhaust gas and wastewater, avoiding the resource waste and incomplete treatment that may occur when treating them separately, and improving resource utilization efficiency and environmental governance effects.

[0022] Second, the wastewater treated by the wastewater treatment plant enters the sedimentation tank through the second conveying pipe. The wastewater remains in the sedimentation tank for a period of time, allowing suspended solids and sediments to settle to the bottom, thus achieving solid-liquid separation. After sufficient sedimentation, if it is necessary to discharge the treated water, the valve in the third conveying pipe can be opened to discharge the supernatant. The discharged water can be reused or discharged in compliance with standards, depending on the actual situation. The sedimentation tank allows suspended solids and sediments in the wastewater to settle naturally, achieving solid-liquid separation and further purifying the water quality, providing convenience for subsequent water treatment or reuse.

A filter screen 110 is provided on the inner wall of the tower body 101. An exhaust pipe 111 is fixedly connected to the bottom of the tower body 101.

[0032] Through the above technical solution, the waste gas generated during the leather production process is introduced into the tower body 101 through the air inlet pipe 109. The flange on the outside of the air inlet pipe 109 facilitates connection with the waste gas conveying pipeline, ensuring that the waste gas smoothly enters the tower body 101. The internal wiring connection of the booster water pump 105 is existing technology and will not be described in detail here. When the booster water pump 105 is started, water enters the booster water pump 105 through the water inlet pipe 106. After being pressurized, it is conveyed to the distribution pipe 108 through the first conveying pipe 107. The distribution pipe 108 distributes the water to each annular pipe. 103. The water is then sprayed out through the nozzle 104 at the bottom of the annular pipe 103, forming a water mist. The water mist comes into full contact with the exhaust gas inside the tower body 101, and harmful substances in the exhaust gas, such as dust and some soluble gases, are adsorbed or dissolved by the water mist, thus purifying the exhaust gas. After being sprayed, the exhaust gas falls with the water droplets and passes through the filter screen 110 set on the inner wall of the tower body 101. The filter screen 110 further intercepts residual particulate matter and other impurities in the exhaust gas, further purifying the exhaust gas. The waste liquid generated during the spraying process is discharged through the discharge pipe 111 at the bottom of the tower body 101. The bottom of the discharge pipe 111 is fixedly connected to the top of the connecting pipe 202 through a flange, and the waste liquid enters the sewage treatment unit 2 through the connecting pipe 202.

Multiple diverter tubes 108 are provided, and the multiple diverter tubes 108 are respectively connected to the top of multiple annular tubes 103.

[0036] Through the above technical solution, a support ring is fixedly connected to the outside of the tower body 101, and multiple support legs are fixedly connected to the bottom of the support ring. The ends of the multiple support legs away from the support ring are all fixedly connected to the top of the water storage frame 201, so that the tower body 101 can be stably installed above the sewage treatment mechanism to form an integral structure. At the same time, it also provides a channel for the discharge of sewage after the exhaust gas treatment. The layout of the nozzles 104 and the diversion pipes 108 is clarified. The multiple nozzles 104 are distributed in a circumferential array to ensure a wider and more uniform spraying range, which is conducive to the full treatment of exhaust gas. The multiple diversion pipes 108 are connected to the annular pipes 103, which can evenly distribute the liquid delivered by the booster pump 105 into each annular pipe 103, and then spray it out through the nozzles 104, thereby improving the efficiency and quality of exhaust gas treatment.
