Description

Technical Field

[0001] The utility model relates to the technical field of gas-water separation of tail gas water sealing tanks, in particular to a gas-water separator used for tail gas water sealing tanks. Background Art

[0002] The tail gas water seal tank is a device that isolates the tail gas branch from the tail gas main pipe, which can ensure that each monomer tail gas system remains independent of each other and avoid the cross-talk of tail gas; at the same time, it can prevent backfire and stop the spread of flames when a fire occurs. When the exhaust volume of the tail gas system is relatively large, the amount of water vapor volatilized by the water seal tank also increases, and a large amount of liquid is volatilized with the exhaust gas, resulting in a rapid drop in the liquid level, frequent water replenishment, and high water consumption.

[0003] To solve the above problem, the Chinese utility model with the prior art patent number CN219897393U includes: a water seal tank; a separation tank, the separation tank is located above the water seal tank, the top of the separation tank is provided with a discharge port, the bottom of the separation tank is provided with a feed port, the feed port is connected to the output end of the water seal tank through a pipe; a liquid mist collecting member, at least one liquid mist collecting member is arranged in the separation tank. The utility model connects a separation tank above the water seal tank, effectively intercepts the liquid mist in the discharged gas through the liquid mist collecting member in the separation tank, and uses the effect of gravity to return the liquid mist to the water seal tank, thereby slowing down the loss of liquid in the water seal tank, reducing water loss and water replenishment frequency. However, in the prior art, the gas carrying water after passing through the water seal tank enters the separation tank from the outlet at the top of the water seal tank, and the water separated by the separation tank still flows into the water seal tank from the same outlet, which makes the separated water collide with the gas entering the separation tank, and the gas entering the separation tank will carry the separated water into the separation tank again, thereby reducing the gas-water separation efficiency. Therefore, it is necessary to optimize and improve the design of the prior art. Utility Model Content

[0004] In view of the above existing technical problems, the utility model provides a gas-water separator for a tail gas water seal tank, which is characterized by comprising a water seal tank, a gas tank, a separation tank, a liquid infusion pipe, a one-way valve, a first baffle, a screen, and a baffle. The gas outlet arranged at the top of the water seal tank is connected to one end of the gas pipe through a flange, and the other end of the gas pipe is connected to the separation tank. The liquid outlet arranged at the bottom of the separation tank is connected to one end of the liquid infusion pipe, and the other end of the liquid infusion pipe is connected to the return liquid port of the water seal tank through a flange. A one-way valve is installed on the liquid infusion pipe, and a first baffle is installed in the separation tank. A screen is installed in a primary separation cavity formed by one side of the first baffle and the inner wall of the separation tank, and a plurality of baffles are installed in a secondary separation cavity formed by the other side of the first baffle and the inner wall of the separation tank.

[0005] Specifically, the bottom of the separation tank is configured as a conical inclined surface structure, and the liquid outlet of the separation tank is located at the lowest point of the bottom surface inside the separation tank.

[0006] Specifically, the screen is arranged in an inclined structure and installed in the primary separation cavity.

[0007] Specifically, the plurality of baffles are arranged in a staggered manner.

[0008] Specifically, a reinforcing rib is provided at the connection between the first baffle plate and the inner top wall of the separation tank to enhance the stability of the installation of the first baffle plate.

[0009] Specifically, the liquid return port is arranged on a side of the water seal tank.

[0010] Specifically, an exhaust port is provided on the top of the separation tank.

[0011] Beneficial effects of the utility model:

[0012] The utility model arranges an air outlet at the top of the water seal tank and connects it to the separation tank through an air delivery pipe. The liquid outlet of the separation tank is connected to a liquid return port arranged at the upper side of the water seal tank through a liquid delivery pipe. The gas carrying water enters the separation tank from the top air outlet, and the separated liquid returns from the liquid return port on the side of the water seal tank, thereby reducing the collision between the separated liquid and the gas and enhancing the separation effect. A one-way valve is installed on the liquid delivery pipe to prevent liquid reflux.

[0013] The gas carrying water enters the separation tank, enters the primary separation cavity and hits the first baffle and the screen. During the collision, the granular liquid water gathers into water clusters and flows down the baffle to the bottom of the separation tank. After the initial separation, the medium enters the secondary separation cavity again, and the water is separated by multiple groups of baffles arranged in an staggered manner. The continuous two separations improve the water separation rate. BRIEF DESCRIPTION OF THE DRAWINGS
