Gas generation and storage integrated biomass pool

Abstract

The invention discloses a gas generation and storage integrated biomass pool, comprising a biomass pool body (1), a discharge water sealing pipe (2), an inclined charging pipe (3) and a top cover. The gas generation and storage integrated biomass pool is characterized in that: the top cover is a floating top cover (1) installed in the biomass pool body, the bottom surface of the floating top cover is provided with a pulley frame (7) and a pulley (8), and the pulley is inserted into a slide rail (9) at the inner wall of the biomass pool body. A counter weight (6) is installed on a base beam a framework (4) of the floating top cover. A grate (12) is installed at the inlet of the inclined charging pipe. In the invention, the integration of gas generation and gas storage of the biomass pool is achieved by the arrangement of the floating top cover and the counter weight, the ratios of gas generation and gas storage are high, and the air pressure in the biomass pool is constant and adjustable, thereby the normal and stable work of marsh gas appliances is guaranteed; simultaneously, the floating top cover is detachable, people can pull out and clean residues outside the biomass pool, which is safe and convenient; in addition, the arranged grate prevents larger objects, such as plastic bags, tree branches and the like from entering the biomass pool.

Description

technical field [0001] The invention belongs to a biogas digester, in particular to a biogas digester with high gas output, an independent gas storage device, and constant and adjustable air pressure. Background technique [0002] Since the use of biogas can effectively utilize rural waste and improve the rural environment, with the development of biogas science and technology in China, the construction of biogas digesters has been rapidly promoted in rural areas. The general structure of the current biogas digester is as follows: Figure 4 As shown, it includes a biogas digester body 1, a discharge water-sealed pond 2, an inclined feed pipe 3 and an arched hard top cover 4, wherein the arched hard top cover 4 is connected with the biogas digester body 1, the discharge water-sealed pond 2, The inclined feeding pipe 3 is an integral structure, and the arched hard top cover 4 cannot move up and down in the pool body, nor can it be disassembled.

Problems solved by technology

The general structure of the current biogas digester is as follows: Figure 4 As shown, it includes a biogas digester body 1, a discharge water-sealed pond 2, an inclined feed pipe 3 and an arched hard top cover 4, wherein the arched hard top cover 4 is connected with the biogas digester body 1, the discharge water-sealed pond 2, The inclined feed pipe 3 is an integral structure, and the arched hard top cover 4 cannot move up and down in the pool body, nor can it be disassembled

The structure of the biogas digester has the following disadvantages: first, the construction of the arched hard roof of the biogas digester is difficult and the construction cost is high

Second, the gas supply pressure and gas production are not stable; the traditional biogas digester does not have an independent gas storage device, it uses pressure to discharge the reactor space to store gas, as the gas storage increases, the reactor space will decrease, and the gas volume will increase It will also decrease accordingly. The gas supply pressure of the biogas digester changes with the gas volume in the biogas digester. Because the arched hard top cover 4 cannot move up and down in the pond, the gas storage capacity cannot be adjusted, and the biogas pressure in the pond cannot be adjusted artificially, resulting in Gas equipment does not work normally and stably

Third, the biogas digester will produce scum and sediment after long-term use. If it is not cleaned regularly, the biogas digester will not work stably or even be abandoned.

At present, the cleaning of the biogas digester requires workers to enter the pond from the inclined feed pipe 3 to clean it. The workload is very heavy, and because there is a large amount of harmful gas in the digester, it will bring great harm to the personnel entering the biogas digester.

Fourth, the inclined feeding pipe 3 is directly connected to the outside world, and larger objects (such as plastic bags, branches, etc.) will enter the biogas digester due to windy reasons. The effective volume of the biogas digester reduces the gas production
