Description

Technical Field

[0001] This utility model relates to the field of gas-liquid separation equipment technology, and in particular to a gas-liquid separation device for a fully enclosed white water system. Background Technology

[0002] The core objective of a fully enclosed white water system is to achieve water recycling and chemical / substance recovery. It achieves "zero discharge" by treating and reusing all wastewater (i.e., "white water") generated during the production process.

[0003] In a fully enclosed white water circulation system, gas-liquid separation is a critical step. Existing separation devices often use simple baffles or packing, which result in incomplete separation and difficulty in capturing small droplets. In addition, white water usually has a certain temperature, and direct venting of the separated gas will lead to heat loss and increase the energy consumption for reheating the system. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing separation devices often use simple baffles or packing, resulting in incomplete separation and difficulty in capturing fine droplets. Therefore, this invention proposes a gas-liquid separation device for a fully enclosed white water system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A gas-liquid separation device for a fully enclosed white water system includes a tank, an air inlet pipe fixedly connected to the outside of the tank, a liquid outlet pipe fixedly connected to the bottom of the tank, and an installation pipe fixedly connected to the top of the tank. It also includes: The separation assembly includes an inclined baffle plate fixedly connected to the top wall of the tank, a spiral filter plate fixedly disposed below the inclined baffle plate, and a filter element fixedly disposed inside the mounting pipe. The auxiliary components include a heat exchanger fixedly connected to the outside of the tank, a flow guide pipe fixedly connected to the output end of the heat exchanger, and a flow stabilizing column fixedly connected to the outside of the flow guide pipe. The flow stabilizing column is fixedly installed inside the tank.

[0006] As a preferred technical solution of this application, the inner bottom wall of the tank is provided with a receiving funnel, the lower end of the receiving funnel is located at the upper end of the drain pipe, a vibration motor is fixedly connected to the outside of the receiving funnel, and a valve is provided on the outside of the drain pipe.

[0007] As a preferred technical solution of this application, both ends of the flow stabilizing column are fixedly connected to conical blocks, and several heat-conducting plates are fixedly connected to the outside of the flow stabilizing column, with the heat-conducting plates fixedly connected to the inside of the tank.

[0008] As a preferred technical solution of this application, an annular pipe is fixedly connected to the inner top wall of the tank, an inlet pipe is fixedly connected to the outside of the annular pipe, and a nozzle is fixedly connected to the inside of the annular pipe.

[0009] As a preferred technical solution of this application, the nozzle is disposed on the upper side of the inclined baffle, and one end of the water inlet pipe penetrates through the outside of the tank.

[0010] As a preferred technical solution of this application, a threaded mounting plate is fixedly connected to the top end of the mounting tube, and a threaded hole is opened in the middle of the threaded mounting plate. The filter element is fixedly connected to the inside of the mounting tube through the threaded hole.

[0011] As a preferred technical solution of this application, a threaded mounting block is fixedly connected to the top of the filter element, the threaded mounting block is threadedly connected to the inside of the threaded hole of the threaded mounting plate, an exhaust pipe is fixedly connected to the top of the filter element, and a sealing plate is fixedly connected to the top of the threaded mounting block.

[0012] Compared with the prior art, this utility model provides a gas-liquid separation device for a fully enclosed white water system, which has the following beneficial effects: 1. Through the installation of spiral filter plates and inclined baffles, the exhaust gas is effectively buffered after entering the tank by the action of the flow stabilizing column and conical block, and forced to change direction. It diffuses evenly in all directions along the flow stabilizing column and conical block, reducing the flow velocity and forming a stable annular settling zone. The droplets settle efficiently. Then, the gas passes through the multiple filtration of the spiral filter plates and inclined baffles. The airflow is forced to change direction multiple times. The droplets collide with the plate wall due to inertia, coalesce, and flow down the plate surface, increasing the chances of gas-liquid contact and separation.

[0013] 2. With the help of the flow stabilizing column, when the exhaust gas is buffered and diverted by the flow stabilizing column, the gas will fully contact the flow stabilizing column and the heat conduction plate. As a result, the temperature inside the exhaust gas will be transferred to the guide pipe. The guide pipe is filled with heat exchange medium, which will then transport the temperature inside the exhaust gas to the heat exchanger, thereby reducing the temperature of the gas and making it easier to filter and separate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model. Example

[0017] Reference Figure 1-3 A gas-liquid separation device for a fully enclosed white water system includes a tank 1, an air inlet pipe 101 fixedly connected to the outside of the tank 1, a drain pipe 102 fixedly connected to the bottom of the tank 1, and an installation pipe 4 fixedly connected to the top of the tank 1. It also includes a separation component and an auxiliary component: the separation component includes an inclined baffle plate 201 fixedly connected to the inner top wall of the tank 1, a spiral filter plate 2 fixedly disposed below the inclined baffle plate 201, and a filter element 402 fixedly disposed inside the installation pipe 4; the auxiliary component includes a heat exchanger 5 fixedly connected to the outside of the tank 1, a guide pipe 501 fixedly connected to the output end of the heat exchanger 5, and a flow stabilizing column 502 fixedly connected to the outside of the guide pipe 501. The flow stabilizing column 502 is fixedly disposed inside the tank 1.

[0018] After the gas-liquid mixture enters the tank 1 through the inlet pipe 101, it is dispersed by the flow stabilizer 502. The heat exchanger 5 then introduces the heat exchange medium, which is transported to the flow stabilizer 502 through the guide pipe 501 and flows out evenly from it. This effectively absorbs the temperature in the gas and improves the separation effect. Then, the gas impacts the spiral filter plate 2, which achieves the initial separation of gas and liquid. Subsequently, the gas carries the remaining liquid droplets and rises to impact the inclined baffle plate 201. Due to inertia, the droplets coalesce on the surface of the inclined baffle plate 201 and fall. The preliminarily purified gas continues to rise to the installation pipe 4 and passes through the filter element 402 for final fine filtration. The completely separated liquid is discharged through the drain pipe 102, achieving efficient and stable separation of gas and liquid.

[0019] Reference Figure 2 , Figure 3 and Figure 4 A gas-liquid separation device for a fully enclosed white water system is further provided with a receiving funnel 104 on the inner bottom wall of the tank body 1. The lower end of the receiving funnel 104 is located at the upper end of the drain pipe 102. A vibration motor 105 is fixedly connected to the outside of the receiving funnel 104. A valve 103 is provided to the outside of the drain pipe 102. Conical blocks 504 are fixedly connected to both ends of the flow stabilizing column 502. Several heat-conducting plates 503 are fixedly connected to the outside of the flow stabilizing column 502. The heat-conducting plates 503 are fixedly connected to the inside of the tank body 1.

[0020] The periodic operation of the receiving funnel 104 combined with the vibrating motor 105 effectively guides and shakes off solid deposits and fiber clumps that have accumulated at the bottom of the tank 1, ensuring that they are smoothly discharged through the drain pipe 102. This significantly reduces the risk of blockage in the drain pipe 102. The valve 103 enables precise control of the drainage process. Meanwhile, the conical blocks 504 at both ends of the flow stabilizer 502 optimize the fluid distribution pattern on its surface, effectively reducing the intensity of local eddies. Combined with the heat-conducting plate 503 fixedly connected to the inner wall of the tank 1, the structural stability of the tank 1 is enhanced, and heat exchange is facilitated to reduce the temperature of the gas. The heat-conducting plate 503 achieves heat balance and dissipation.

[0021] Among them, an annular pipe 301 is fixedly connected to the inner top wall of the tank body 1, a water inlet pipe 3 is fixedly connected to the outside of the annular pipe 301, and a nozzle 302 is fixedly connected to the inside of the annular pipe 301; the nozzle 302 is located on the upper side of the inclined baffle plate 201, and one end of the water inlet pipe 3 penetrates through the outside of the tank body 1.

[0022] After the device has been running for a period of time, flushing water or chemical cleaning agent can be injected into the inlet pipe 3 through an external water source. The fluid then enters the annular pipe 301 and is evenly distributed to each nozzle 302. The nozzles 302 spray the liquid downwards to cover the entire surface of the inclined baffle 201. This effectively flushes away the fiber flocs and solid scale accumulated on the inclined baffle 201, restoring its original high-efficiency separation surface. The inclined structure of the inclined baffle 201 ensures that the flushing waste liquid can flow quickly to the bottom of the tank 1 by gravity and be discharged through the drain pipe 102, thereby realizing the online cleaning and maintenance of the core separation component without stopping the machine. This ensures the stability and reliability of the separation performance of the device under long-term continuous operation. The impurities flushed down will fall onto the spiral filter plate 2, and under the impact of the water flow, they will fall into the inside of the receiving funnel 104.

[0023] Reference Figure 3 and Figure 5 A gas-liquid separation device for a fully enclosed white water system is further provided, wherein a threaded mounting plate 401 is fixedly connected to the top end of the mounting pipe 4, and a threaded hole is provided in the middle of the threaded mounting plate 401. The filter element 402 is fixedly connected to the inside of the mounting pipe 4 through the threaded hole. A threaded mounting block 403 is fixedly connected to the top end of the filter element 402, and the threaded mounting block 403 is threadedly connected to the inside of the threaded hole of the threaded mounting plate 401. An exhaust pipe 404 is fixedly connected to the top of the filter element 402, and a sealing plate 405 is fixedly connected to the top of the threaded mounting block 403.

[0024] The threaded connection between the threaded mounting block 403 and the threaded mounting plate 401 allows the filter element 402 to be quickly and reliably installed inside or removed from the mounting tube 4, greatly simplifying the maintenance process. The sealing plate 405 at the top fits tightly with the threaded mounting plate 401, forming an effective sealing interface to ensure that no gas leakage occurs. All gas must be purified through the filter element 402, and the clean gas after separation is discharged through the exhaust pipe 404 fixedly connected to the top of the filter element 402.

[0025] Specifically, in use, the liquid mixture first enters the tank 1 through the inlet pipe 101, contacts the flow stabilizing column 502 at the inlet and is effectively dispersed. The conical blocks 504 at both ends of the flow stabilizing column 502 continuously optimize the fluid distribution. At this time, the heat exchanger 5 continuously delivers the heat exchange medium to the guide pipe 501. The medium flows through the flow stabilizing column 502 and flows out evenly from it. This process not only absorbs excess heat from the gas, but also significantly improves the subsequent separation efficiency through temperature regulation. The pretreated gas-liquid mixture then impacts the spiral filter plate 2, achieving the initial separation of gas and liquid. The separated gas, carrying the remaining droplets, continues to rise and impacts the surface of the inclined baffle plate 201. Under inertia, the droplets coalesce on the surface of the baffle plate and fall. The initially purified gas continues to rise to the installation pipe 4, passes through the filter element 402 for final fine filtration, and is... The completely separated liquid falls down the tank wall. When the device needs cleaning, rinsing liquid can be injected into the annular pipe 301 through the water inlet pipe 3. The inclined baffle plate 201 is fully rinsed through the nozzle 302. The impurities washed off pass through the spiral filter plate 2 with the liquid flow and finally fall into the receiving funnel 104. The liquid and solid impurities collected at the bottom of the tank 1 are periodically vibrated in the receiving funnel 104 by the vibration motor 105 to effectively prevent sedimentation and agglomeration. They are then smoothly discharged through the drain pipe 102 controlled by the valve 103. The filter element 402 installed at the top is connected to the threaded mounting plate 401 through the convenient connection structure of the threaded mounting block 403 and the reliable sealing of the sealing plate 405, ensuring that all the purified gas is discharged through the exhaust pipe 404. This achieves continuous and efficient gas-liquid separation operation of the entire device in a fully enclosed environment.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
