Description

Technical Field

[0001] This utility model relates to a gas-liquid separation plate. Background Technology

[0002] Currently, gas-liquid separation includes inertial force separation, centrifugal force separation, and capillary force separation, corresponding to corrugated plate separators, cyclone separators, and wire mesh separators. Among them, wire mesh separators are widely used due to their simple structure, low cost, and low separation pressure. However, gas-liquid separators still have certain problems, among which the secondary carryover of liquid droplets during the gas-liquid separation process is particularly prominent.

[0020] like Figures 1 to 4 The gas-liquid separation plate shown is installed at a 45-degree angle to the horizontal plane and located at the air outlet. The gas-liquid separation plate 1 consists of an outer protective plate 2, a medium-efficiency filter cotton 3, a coarse-efficiency filter cotton 4, a packing layer 5, and an aluminum grid 6 in sequence, for the discharge of clean gas and the recovery of liquid.

[0021] The outer protective plate 2 is made of 1.2mm thick perforated galvanized steel plate with a perforation-to-plate ratio of 2:5 and an air permeability of 40%. A drainage groove 8 is provided at one end of the outer protective plate 2 for recycling the separated liquid.

[0022] The medium-efficiency filter cotton 3 and the coarse-efficiency filter cotton 4 are made of open-pore polyurethane fiber sponge for exhaust gas purification. The medium-efficiency filter cotton 3 has a filtration accuracy of F5 grade, and the coarse-efficiency filter cotton 4 has a filtration accuracy of G4 grade. They absorb particulate matter in positive pressure airflow, including droplets and dust mixed particles.

[0023] The filler layer 5 uses hollow sphere filler, the hollow sphere is made of PVC plastic, and the filler layer 5 has a thickness of more than 100mm to prevent airflow rebound.

[0024] The aluminum grille 6 is made of aluminum alloy with a thickness of 3mm or more, and is designed to withstand wind pressure of 4000pa. Several grille plates 7 are installed on the aluminum grille 6 at a 45-degree angle. They are opaque in the vertical direction. The grille plates 7 are 50mm or more wide to retain liquid. The water droplets falling on the grille plates 7 flow downwards in sequence and eventually flow into the drainage trough 8.

[0025] In this embodiment, a gas-liquid mixture containing particulate pollutants flows into the gas-liquid separation plate 1 at a 45-degree angle with positive pressure. A portion of the gas flows through the gas-liquid separation plate 1, filtering out the particulate pollutants, while the liquid remains in the gas-liquid separation plate 1, achieving gas-liquid separation and purification, which can be directly discharged. The liquid retained in the gas-liquid separation plate 1, such as the dripping water falling on the grid plate 7, flows towards the drainage trough 8 under the action of gravity. In addition, the liquid retained in the packing layer 5, the coarse filter cotton 4, and the medium filter cotton 3 also accumulates slowly and flows towards the drainage trough 8 under the action of gravity. Finally, all the liquid retained in the gas-liquid separation plate 1 flows into the drainage trough 8, ensuring effective liquid recovery.

[0026] Another portion of the airflow is reflected back. The returned airflow is partially purified airflow, which has already passed through the packing layer 5 and the coarse filter cotton 4. Large particles in the airflow have been intercepted, and only small particulate pollutants are present, requiring further purification.

[0027] The above embodiments are merely illustrative examples of this utility model and are not intended to limit the scope of protection of this utility model. Those skilled in the art can make simple changes or substitutions based on the above embodiments without departing from the technical concept of this utility model, but these changes will still fall within the scope of protection of this utility model.
