Abstract
Description
Technical Field
[0001] This utility model relates to the field of degassing tank technology, and in particular to an acidic water degassing tank for use in environmental protection equipment. Background Technology
[0002] In the field of environmental protection, with the rapid development of industrial production, the discharge of various industrial wastewaters continues to increase. Among them, acidic wastewater contains a large amount of acidic substances and harmful gases. If it is discharged directly without proper treatment, it will cause serious pollution to the ecological environment such as soil and water, endangering the ecological balance and human health. For example, in the chemical, metallurgical and electroplating industries, a large amount of acidic wastewater is generated during the production process. This wastewater is not only highly acidic, but also contains dissolved gases such as hydrogen sulfide and carbon dioxide. Traditional treatment methods are difficult to efficiently remove harmful gases from acidic water and achieve standard discharge. The high temperature and humidity environment generated during the degassing process in the existing equipment causes a large amount of water vapor to mix into the degassed gas. The large amount of water vapor mixed into the gas will make the subsequent gas treatment process more complicated and increase the treatment cost. For example, if the gas needs to be chemically absorbed or catalytically reacted later, the presence of water vapor may affect the rate and effect of the chemical reaction, or even cause corrosion damage to the treatment equipment. Therefore, the above problems need to be improved. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an acidic water degassing tank for environmental protection equipment.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: an acidic water degassing tank for environmental protection equipment, comprising a tank body, an overlapping ring at the lower end of the tank body, a support abutting the bottom surface of the overlapping ring, a support platform at the bottom end of the support, a water pump on the support platform, a vacuum machine on one side of the water pump, an air inlet pipe of the vacuum machine connected to one end of a pipeline via a flange, a separation component connected to the other end of the pipeline via a flange, a connecting flange pipe connected to one side of the top of the separation component via a flange, and a top cover connected to the end of the connecting flange pipe.
[0005] Preferably, the bottom surface of the top cover fits into the top of the tank, multiple fixing bolts pass through the periphery of the top cover and the tank, an observation window is provided on one side of the outer wall of the tank, the bottom of the tank is funnel-shaped, and the bottom of the tank is connected to the liquid inlet of the water pump.
[0006] Preferably, the pipeline is equipped with a pressure gauge, and a water inlet pipe is provided on one side of the upper end of the tank, with a valve on the body of the water inlet pipe.
[0007] Preferably, the separation component includes a cyclone separator tank, the bottom of which is connected to a wastewater tank, the wastewater tank being fixed to the outer wall of the tank body, and a drain pipe being provided on one side of the wastewater tank.
[0008] Preferably, the cyclone separator is provided with an airflow pipe at its axial center, the top end of the airflow pipe is open and connected to a pipeline, and a guide vane is spirally provided on the outer wall of the airflow pipe, the guide vane abutting against the inner wall of the cyclone separator.
[0009] Preferably, a baffle is installed at the bottom of the inner wall of the cyclone separator, and the bottom cross-section of the cyclone separator is conical.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of a cyclone separator, an airflow pipe, and guide vanes, with the airflow pipe axially positioned and its top side opening connected to a pipeline, and guide vanes spirally arranged on the outer wall to abut against the inner wall of the cyclone separator, allows the degassed mixed gas to enter the cyclone separator. The guide vanes guide the gas to move in a spiral motion, using centrifugal force to separate water vapor from the gas, facilitating efficient gas-water separation and improving the purity of the degassed gas. This simplifies the subsequent gas treatment process. Furthermore, through the connection between the bottom of the cyclone separator and the wastewater tank, the separated water vapor flows into the wastewater tank, facilitating centralized collection and treatment of the separated water. This improves the treatment efficiency of water vapor generated during the degassed process, thereby reducing the treatment costs and equipment corrosion risks caused by water vapor mixing into the gas. Ultimately, this solves the problem of high water vapor content in the degassed gas of existing equipment, which leads to complex subsequent treatment processes, increased costs, and susceptibility to equipment corrosion damage. It also improves the efficiency and stability of acidic water degassed gas and subsequent gas treatment. Attached Figure Description

[0014] Example: See Figure 1-4This utility model discloses an acidic water degassing tank for environmental protection equipment, comprising a tank body 1. An overlapping ring is provided at the lower end of the tank body 1, and a support 2 is abutted against the bottom surface of the overlapping ring. A support platform is provided at the bottom end of the support 2, and a water pump 3 is mounted on the support platform. A vacuum machine 4 is mounted on one side of the water pump 3. The air inlet pipe of the vacuum machine 4 is connected to one end of a pipe 5 via a flange. A separation component is flanged at the other end of the pipe 5. A connecting flange pipe 9 is flanged to one side of the top of the separation component, and a top cover is connected to the end of the connecting flange pipe 9. This structure provides a stable support for the acidic water degassing tank. The support and connection base, tank 1 is generally made of 304 stainless steel, which has good corrosion resistance and can withstand the erosion of acidic water; water pump 3 is an ISG series pump, which has stable performance and can provide stable water flow power to ensure the efficiency of acidic water delivery; vacuum machine 4 is a 2XZ series vacuum machine, which has strong air extraction capacity and can effectively reduce the air pressure inside tank 1, improving the degassing effect. Supported by bracket 2, tank 1, together with water pump 3 and vacuum machine 4, facilitates the delivery and degassing of acidic water, improving the stability and operability of the degassing process. The top cover fits snugly against the top of the tank body 1. Multiple fixing bolts pass through the circumference of the top cover and tank body 1. An observation window 6 is located on one side of the outer wall of the tank body 1. The bottom of the tank body 1 is funnel-shaped and connected to the inlet of the water pump 3. The tight fit between the top cover and the tank body 1, secured with fixing bolts, ensures the airtightness of the tank body 1. The 304 stainless steel material of the tank body 1 ensures the durability of the sealing structure. The observation window 6 allows operators to observe the internal conditions of the tank in real time. The funnel-shaped bottom design, combined with the inlet of the water pump 3, facilitates the discharge of degassed acidic water, improving the smoothness of acidic water discharge. Smoothness and efficiency: The stable operation of water pump 3 ensures efficient drainage; a pressure gauge is installed on pipe 5, and an inlet pipe 10 is installed on one side of the upper end of tank 1, with a valve on the pipe body of inlet pipe 10; the pressure gauge can monitor the air pressure in pipe 5 in real time, providing a basis for operators to adjust the working status of vacuum machine 4, improving the controllability of the degassing process; pipe 5 is generally made of PVC pressure-resistant and corrosion-resistant pipe material to ensure the accuracy of air pressure monitoring and the service life of pipe 5; the setting of inlet pipe 10 and valve facilitates the control of the amount and flow rate of acidic water entering, enhancing the flexibility of equipment operation.
[0015] In this invention, the separation assembly includes a cyclone separator 8, with a wastewater tank 7 connected to the bottom of the cyclone separator 8. The wastewater tank 7 is fixed to the outer wall of the tank body 1, and a drain pipe is provided on one side of the wastewater tank 7. The cyclone separator 8 can separate water vapor from the degassed gas. The cyclone separator 8 is made of 304 stainless steel, which has good strength and corrosion resistance. The wastewater tank 7 is used to collect the separated water vapor, and the drain pipe facilitates the discharge of wastewater, improving the efficiency of gas-water separation and the convenience of wastewater treatment. The material of the wastewater tank 7 is the same as that of the tank body 1, ensuring the consistency and durability of the overall structure. An airflow pipe 12 is provided at the axis of the cyclone separator 8. The top end of the airflow pipe 12 is open and connected to the pipe 5. A guide vane 11 is spirally provided on the outer wall of the airflow pipe 12, and the guide vane 11 abuts against the inside of the cyclone separator 8. The gas flow pipe 12, guide vane 11, and cyclone separator 8 work together to make the gas entering the cyclone separator 8 spiral, using centrifugal force to efficiently separate gas and water. The gas flow pipe 12 and guide vane 11 are usually made of 304 stainless steel, which has good smoothness and corrosion resistance, helping to improve the gas-water separation effect. This structural design improves the purity of the degassed gas and reduces the difficulty of subsequent gas treatment. A baffle 13 is installed at the bottom of the inner wall of the cyclone separator 8, and the bottom section of the cyclone separator 8 is conical. The baffle 13 can prevent the separated water vapor from being re-entrained into the gas. The conical bottom design facilitates the smooth flow of water vapor into the wastewater tank 7. The baffle 13 is made of 304 stainless steel, which ensures its durability in humid and acidic environments, further improving the gas-water separation effect and wastewater collection efficiency.
[0016] Working Principle: In use, acidic water flows into tank 1 through inlet pipe 10. The valve on inlet pipe 10 can flexibly control the inflow rate and velocity. Vacuum machine 4 is started, and air is drawn into tank 1 through pipe 5 to reduce the air pressure, causing dissolved gases in the acidic water to escape, thus achieving degassing. During this period, the pressure gauge on pipe 5 monitors the air pressure in real time, assisting the operator in adjusting the working state of vacuum machine 4. The degassed mixed gas enters cyclone separator 8. Inside the tank, airflow pipe 12, in conjunction with spiral guide vanes 11 on the outer wall, guides the gas to move in a spiral motion, using centrifugal force to achieve gas-water separation. The heavier water vapor is thrown towards the tank wall and flows downward along the wall. The baffle 13 at the bottom of the inner wall of cyclone separator 8 prevents the separated water vapor from mixing back into the gas. The separated water vapor gathers under gravity and flows into the wastewater tank 7 connected to it. The drain pipe on one side of the wastewater tank 7 can periodically discharge wastewater. The pure gas after gas-water separation is discharged through connecting flange pipe 9 and enters the subsequent treatment stage. At this point, the device is in use.
