Description

Technical Field

[0001] The utility model belongs to the technical field of gas-water separation equipment, and specifically relates to a gas-water separator. Background Art

[0002] Methane is the simplest hydrocarbon. It is widely found in natural gas, biogas, and coal mine gas. It is a high-quality gas fuel and an important raw material for making synthesis gas and many chemical products. At the molecular level, methane is a more active greenhouse gas than carbon dioxide, but its quantity in the atmosphere is relatively small. Methane is mainly used as a fuel, such as natural gas and coal gas, and is widely used in civil and industrial applications. As a chemical raw material, it can be used to produce acetylene, hydrogen, synthetic ammonia, carbon black, nitromethane, carbon disulfide, methyl chloride, dichloromethane, chloroform, carbon tetrachloride, and hydrocyanic acid.

[0003] In the production process of methane, a large amount of steam will be carried, and it needs to be separated from gas and water to obtain high-purity and relatively dry methane gas as a chemical raw material. The existing gas-water separation device mainly adopts two separation methods: condensation and activated carbon adsorption. When activated carbon adsorption is adopted, the gas-water separation effect will be greatly reduced after the activated carbon reaches saturation, while gas-water separation by condensation is not subject to this limitation. By utilizing the different liquefaction temperatures of natural gas and water vapor, a condenser (condenser) is connected to the pipeline, one end of the condenser is connected to the air inlet pipe and the other end is connected to the air outlet pipe, and the water-containing methane enters the condenser. The natural gas is cooled by the condenser, and the water vapor condenses into water droplets and is discharged from the water outlet of the condenser, thereby achieving gas-water separation. However, due to the continuous flow of methane, the methane leading to the condenser will flow out quickly, resulting in a short stay time in the condenser and a poor condensation effect. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art and provide a gas-water separator to improve the condensation effect, the degree of water-gas separation and the purity of methane.

[0006] Through the above scheme, the setting of the speed regulating mechanism reduces the speed of the gas-water mixture entering the separation box through the overlap and misalignment of the first speed regulating hole and the second speed regulating hole, and performs preliminary cooling during the time it stays at the upper end of the separation box, and then performs final cooling through the condensation mechanism, so that the water vapor can be cooled to form liquid water and discharged from the drain pipe, and the gas is secondary separated through the adsorption mechanism, further improving the degree of water-gas separation.

[0007] Preferably, the adsorption mechanism comprises a super absorbent resin layer and an anhydrous calcium chloride layer, the super absorbent resin layer and the anhydrous calcium chloride layer are arranged in parallel, the super absorbent resin layer is arranged below the anhydrous calcium chloride layer, and the air outlet pipe is arranged above the anhydrous calcium chloride layer.

[0008] Through the above scheme, the super absorbent resin layer undergoes a primary adsorption treatment, and the anhydrous calcium chloride layer undergoes a secondary adsorption treatment, so that the water content in the gas is less than 0.008%.

[0009] Preferably, the edges of the super absorbent resin layer and the anhydrous calcium chloride layer are both engaged with the inner wall of the separation box, and one side of the super absorbent resin layer and the anhydrous calcium chloride layer penetrates the wall of the separation box and is sealed and connected to the separation box.

[0010] Through the above scheme, the super absorbent resin layer and the anhydrous calcium chloride layer are connected to the separation box by snapping, which is convenient for replacing the super absorbent resin and the anhydrous calcium chloride and ensures their water absorption effect.

[0011] Preferably, the condensation mechanism includes multiple condensation layers, the condensation layers are arranged below the speed regulating mechanism, the condensation layers are provided with multiple ventilation holes, the condensation layers are hollow structures, the condensation layers are connected through a water inlet pipe, one end of the water inlet pipe passes through the partition and extends to the top of the separation box; the other end of the water inlet pipe passes through the lower end of the separation box; the drain pipe is provided below the condensation layer.

[0012] Through the above scheme, the setting of the condensation mechanism makes it easy to cool the gas-water mixture multiple times to ensure the condensation effect.

[0013] Preferably, the upper end of the drain pipe is abutted against an inclined surface, the lowest point of the inclined surface abuts against the upper end of the drain pipe, and the upper end of the inclined surface is arranged below the partition.

[0014] Through the above solution, the setting of the inclined surface ensures that the water in the separation box is discharged, and further slows down the speed of entering the adsorption mechanism, thereby ensuring the adsorption treatment effect.

[0015] Preferably, the air intake mechanism includes an air intake pump, the output end of the air intake pump is connected to the upper end of the separation box and is connected to an air intake pipe, the air intake pipe is a U-shaped pipe, the outlet end of the air intake pipe is funnel-shaped, and a float is provided at the outlet end of the air intake pipe.

[0017] The beneficial effects of the utility model are as follows: by setting the speed regulating mechanism, the flow rate of the gas-water mixture is reduced, and it will not pass through the condensation mechanism quickly to affect the condensation effect, thereby ensuring a high degree of gas-water separation; the setting of the condensation mechanism performs multi-stage condensation, improves the condensation effect, and further improves the gas-water separation degree; the setting of the adsorption mechanism further improves the gas-water separation degree.
