CN201162009Y - Double outlet biogas generator tank - Google Patents

Abstract

The utility model provides a biogas generating tank with double material outlets, in which a discharge cylinder (4) is arranged at the bottom of the tank body (1), the height of which is greater than that of the biogas generating material (7), and the flange of the discharge cylinder is used at the bottom The disc and gasket (5) are closed. When discharging, the inlet and the discharge cylinder (4) are opened, and the biogas slag is discharged from the discharge cylinder (4). Its positive effects are: convenient manufacturing, transportation and installation; a large amount of low-quality fuel can be used, and the water consumption is small; the gas production rate is high; the material is convenient, safe, and labor-saving; it can be placed in a small plastic shed for easy heating and insulation.

Description

Double outlet biogas generator tank

technical field

The utility model relates to the field of tank type biogas pools.

Background technique

The following substances and corresponding conditions must be met to produce biogas: biogas bacteria, fermentation raw materials, water, airtight containers, certain temperature and pH, etc. These conditions are not available in every region at the same time. At present, the typical hydraulic biogas digesters widely used in rural areas of our country are still in two types: cylindrical and ellipsoidal; conventional biogas digesters buried in the ground generally adopt concrete brick construction technology or cast-in-place concrete construction Built with advanced technology: the highest pool temperature can only reach 25 degrees, and the pool temperature in winter can only reach 5-10 degrees; such temperature is not the best temperature for biogas generation. Although the tank-type biogas digester is easy to manufacture, transport and install, and can be placed in a small plastic shed to keep warm and increase temperature, which can effectively solve this problem, but there is only one sealed feed port at the top of the tank-type biogas digester , for feeding and discharging, such a structure is easy to pollute the tank when discharging slag, and the labor intensity is high.

Utility model content

The problem to be solved by the utility model is to provide a biogas generating tank which facilitates the discharge of biogas slag, and avoids the slag from polluting the tank when discharging the slag;

In the utility model, a discharge cylinder is arranged at the bottom of the biogas tank body, the height of the discharge cylinder is greater than that of the biogas generating material, and the bottom is sealed with a flange plate and a sealing rubber pad. When discharging, open the feed port and the discharge cylinder, and the biogas slag is discharged from the discharge cylinder. This not only facilitates the discharge of material slag, but also increases the gas storage space for biogas.

The beneficial effects are: convenient manufacture, transportation and installation; a large amount of low-quality fuel can be used, and the water consumption is small; the gas production rate is high; the discharge is convenient, safe, and labor-saving; it can be placed in a small plastic shed to facilitate heating and insulation.

Description of drawings

Shown in Fig. 1 is the schematic diagram of the concrete structure of the present utility model.

Detailed ways

The utility model consists of a tank body (1), a biogas conduit (2), a flange plate and a sealing rubber pad (3), a discharge cylinder (4), a discharge cylinder flange plate and a sealing rubber pad (5), a suspension ring ( 8), support (9) constitutes; It is characterized in that: tank body (1) is an airtight container tank, and its feed inlet is provided with the rectangular flange of exhaust duct (2) and sealing rubber pad ( 3) Closed; the bottom of the tank body (1) is welded with the discharge tube (4), the discharge port of the discharge tube (4) is not set correspondingly to the tank body feed port, and the discharge tube flange is used at the end It is closed with sealing rubber gasket (5), and its height is greater than the height of biogas generating material (7). The inner and outer coatings (6) of the tank completely seal the inner and outer structural surfaces of the tank body (1) and the discharge cylinder (4). Tank inner coating and outer coating (6) are anticorrosion coatings, mainly adopt anticorrosion black paint, epoxy asphalt paint, acid-proof asphalt paint or chlorosulfonated polyethylene anticorrosion coatings etc.

Claims (1)
