Description

Biogas water separation automatic drain

technical field

The utility model relates to a gas-water separation and condensed water drainage device for biogas pipelines.

technical background

The biogas produced by artificial use of organic matter contains a large amount of water vapor, which will condense into water when it is cold, and accumulate in the lower part of the gas pipeline, affecting the flow and use of biogas; a large amount of water in the biogas pipeline also weakens the biogas The desulfurization effect of the purifier will affect human health and the service life of biogas equipment. In order to eliminate the hazards of condensed water in biogas pipelines, water storage bottle devices are widely used and installed in buried gas pipelines to store water in the bottle. When the water in the bottle will affect the flow of biogas, Pour out the water in the bottle, but it is difficult to pour the water in time, and it is extremely troublesome to use, and the repeated opening and closing of the device interface is easy to damage the sealing of the gas pipeline, resulting in air leakage and loss of biogas.

Chinese Patent No. 200520024309.0 discloses a gas-water separation automatic drainage device for gas pipelines. The device consists of a water storage cylinder (shell) and a valve (float) inside the water storage cylinder. The valve can move up and down in the water storage cylinder. The upper part of the valve is a sealed tank, and the lower part is a column with a cone head at the bottom. In order to realize the sealing of the tank, a sealing cover must be installed. The disadvantage is that there is a small gap for the biogas to pass through the top of the water storage tank, the residence time of the biogas in the water storage tank is short, and the top of the valve is flat, which is not conducive to increasing the biogas. dehydrating effect. In addition, Hebei Longfeiteng Biogas Equipment Co., Ltd. designs, produces and sells biogas, gas, and water automatic separation drains. The center of the upper part of the valve is an upward open circular hole, and a downward annular groove is added outside the central circular hole. The disadvantage is that in addition to the small gap at the top of the water storage tank, the top of the valve is not only flat, but also there is water in the middle of the top surface, which is not conducive to improving the separation effect of biogas and water. At the same time, the valves in the above-mentioned two kinds of biogas pipeline gas-water separation automatic drainage devices have the problems of complex structure and shape, heavy weight, large amount of materials, and high processing cost.

Contents of the invention

The main purpose of this utility model is to improve the gas-water separation effect of the device on biogas; another purpose of this utility model is to simplify the structure and shape of the valve, reduce the amount of materials used, so as to reduce production costs.

In order to achieve the above object, the utility model adopts the following solutions:

The biogas gas water separation automatic drain is composed of a water storage tank and a valve in the water storage tank. The upper part of the water storage tank has a biogas inlet and a biogas outlet, and a screw cap at the bottom. There is a drainage hole under the screw cap. Sealing pad, valve has upper body and lower body, and lower body has garden-shaped conical head, and upper body is garden cylinder or inverted tank body lighter than water.

Because the material of the upper body of the valve is lighter than water and the accumulated water cannot enter the inverted tank, the small amount of accumulated water in the accumulated water cylinder can easily make the valve float up to realize automatic drainage. Although the weight of these two valves is lighter than that of the prior art products, because the drainage aperture is smaller than the cone head, the contact surface is extremely small, and the smaller the force-bearing area of the same weight, the greater the pressure. After applying 120 cm of water column in the water storage cylinder Under the condition of air pressure, even if the material of the upper body is more than twice as light as that of the prior art product, the biogas will still not leak from the drainage hole.

The top of the valve in the storage tank of the utility model is spherical or conical in shape, and there is a filter screen between the biogas inlet and the biogas outlet at the top of the storage tank.

The positive effect of the utility model scheme is: (1) due to the addition of a filter screen on the top of the water storage tube, more water in the biogas is intercepted, and the void ratio of the upper part of the water storage tube is improved, so that the biogas in the water storage tube The flow velocity slows down, which is more conducive to intercepting the water in the biogas; the top of the valve is spherical or conical, which can prevent the top of the valve from accumulating water, so that the separated water can quickly flow to the bottom of the water storage tank, minimizing the accumulation of water. The moisture in the water cylinder evaporates toward the biogas outlet, thus effectively improving the dehydration effect of the device on the biogas. (2) Since the valve composed of the upper body and the lower body has simple structure and shape, light material and low processing cost, it is beneficial to reduce the cost and improve the market competitiveness of the product.

Detailed ways

As shown in Figure 1, the biogas gas water separation automatic drain is composed of a water storage tank 4 and valves 5 and 11 inside the water storage tank 4. The upper part of the water storage tank 4 has a biogas inlet 1 and a biogas outlet 2, and a screw cap at the bottom 8. There is a drainage hole 10 under the screw cap 8, and there is a sealing rubber pad 9 between the screw cap 8 and the water storage cylinder 4; Be lighter than water cylinder body 6 or inverted tank body 12.

Shown in Fig. 1 and Fig. 2, the upper body top of the valve 5, 11 is in the form of a spherical or garden cone.

As shown in FIG. 1 , there is a filter screen 3 between the biogas inlet 1 and the biogas outlet 2 .

The working principle of this embodiment is: the biogas water separation automatic drainage device is connected in series to the pipe section of the biogas gas transmission pipeline where water accumulation is easy to form, and the biogas enters the water accumulation cylinder 4 from the biogas inlet 1 of the biogas water separation automatic drainage device, Pass through the filter screen 3, then flow out from the biogas outlet 2. When the biogas passes through the filter screen 3, it can promote the contained water vapor to adhere to the filter screen, and because the water content is relatively large, it will naturally settle in the water storage cylinder 4. Because the valves 5 and 11 are lighter than water and the accumulated water at the bottom of the water storage cylinder 4 cannot enter the inverted tank, when the accumulated water in the lower part of the water storage cylinder 4 increases to a certain extent, the valves 5 and 11 are floated to drain water Hole 10 is opened then, because there is air pressure in the water storage cylinder 4, adds the gravity of water, the accumulated water in the water storage cylinder 4 promptly discharges automatically. When the water in the storage tank 4 was too little to float the valves 5 and 11, the valves 5 and 11 would descend, and the garden cone head 7 of the lower body of the valves 5 and 11 would block the drainage holes 10, so that the air pipes The biogas cannot run out from the drain hole 10.
