Description

A biogas water separator

technical field

The utility model relates to a biogas gas-water separator, which belongs to the technical field of environmental protection.

Background technique

The biogas produced by anaerobic treatment of wastewater contains hydrogen sulfide, which will pollute the air after combustion. Therefore, it is necessary to desulfurize and purify the hydrogen sulfide in the biogas before using it. When dry desulfurization is used, the water and water vapor contained in the biogas will affect the desulfurization, and at the same time, it is easy to corrode the equipment. Therefore, before the dry desulfurization of the biogas, it must be separated from the gas and water to remove the water and water carried in the biogas. Steam, traditional gas-water separation equipment realizes gas-water separation through direct condensation of gas in the equipment, and the separation efficiency is relatively low.

Utility model content

The technical problem to be solved by the utility model is to provide a biogas gas-water separator with good gas-water separation effect, high efficiency, low equipment cost, safety and environmental protection.

The utility model adopts the following technical solutions:

The utility model comprises a tank body provided with a bracket, a liquid discharge pipe arranged at the lower end of the tank body, an air inlet arranged at one side of the tank body, an air outlet and an exhaust valve arranged at the top of the tank body, and a filler is arranged in the tank body A wire mesh support frame is set on the upper end of the filler layer, a wire mesh layer is set on the wire mesh support frame, a liquid level gauge is set at the middle and lower part of the other side of the tank, and the other end of the liquid level gauge is connected to the drain pipe.

The positive effects of the utility model are as follows:

The upper end of the filler layer in the tank body of the utility model adds a wire mesh layer. By setting an appropriate flow velocity in the wire mesh layer, the small liquid droplets entrained in the biogas collide with the wire mesh in the wire mesh layer. During the collision process Small and medium droplets are assembled into large droplets, thus settling under the action of gravity, which increases the removal function of smaller droplets and improves the efficiency of gas-water separation; the wire mesh added to the gas-water separator of the utility model The layer increases the contact area of water vapor, accelerates the condensation of water vapor, reduces the volume of the equipment, reduces the investment cost of the equipment, and also reduces the occupied area of the equipment; The liquid level gauge can observe the liquid level in the tank in time to prevent the toxic gas from leaking from the liquid discharge port after all the liquid is discharged, causing environmental pollution.

Detailed ways

As shown in Figure 1, the utility model includes a tank body 2 provided with a bracket 9, a drain pipe 8 arranged at the lower end of the tank body 2, an air inlet 7 arranged at one side of the tank body 2, and an air inlet 7 arranged at the tank body 2. The air outlet 10 and the exhaust valve 1 at the top are provided with a packing layer 5 in the tank body 2, and the packing layer 5 is arranged on the packing layer support 6 for fixing the packing layer 5, and a wire mesh support frame is arranged at the upper end of the packing layer 5 4. Install the wire mesh layer 3 on the wire mesh support frame 4 , and install a liquid level gauge 11 at the middle and lower part of the other side of the tank body 2 , and the other end of the liquid level gauge 11 communicates with the drain pipe 8 .

The tank body of the utility model includes two parts, the contact condensation part and the gas-water separation part, wherein the contact condensation part is the filler layer 5, and the gas-water separation part is the silk screen layer 4. When working, the biogas with water vapor in the water-sealed tank is discharged from the The air inlet 7 of the utility model enters the tank body 2, the mixed gas first enters the packing layer 5, and the packing layer 5 is filled with stainless steel wire mesh, and the gas contact area is increased through the wire mesh to promote sufficient heat transfer between the biogas and the stainless steel wire mesh. Cool down the biogas, thereby reducing the pressure of the saturated steam, the water vapor condenses into small droplets, some of the droplets fall under the action of gravity, and are discharged from the drain pipe 8 to the outside of the tank 2; The wire mesh layer 4, by setting the appropriate flow velocity of the wire mesh layer, the small liquid droplets entrained in the biogas collide with the wire mesh in the wire mesh layer 4, and the small droplets gather into large droplets during the collision process, thus under the gravity Settling under the action of the liquid discharge pipe 8 to the outside of the tank body 2; the setting of the wire mesh layer 4 improves the removal function of the smaller droplets and improves the gas-water separation efficiency; the utility model gas-water separation The wire mesh layer added in the device increases the contact area of water vapor, accelerates the condensation of water vapor, reduces the volume of the equipment, reduces the investment cost of the equipment, and also reduces the occupied area of the equipment; in addition, in this practical A liquid level gauge is installed on one side of the new tank body, which can observe the liquid level in the tank body in time to prevent toxic gas from leaking from the liquid discharge port after all the liquid is drained, causing environmental pollution.
