Abstract
Description
Technical Field
[0001] The device relates to an automatic voltage stabilizing device for a biogas storage cabinet. Background Art
[0002] The biogas storage tank is composed of an outer membrane, an inner membrane, a bottom membrane and auxiliary equipment. It has the ability to resist ultraviolet rays and various organisms and is highly fireproof. An airtight space with variable capacity is formed between the inner membrane and the bottom membrane to store biogas, and the outer membrane constitutes the spherical shape of the gas storage tank. The device can be used to achieve pressure stabilization control of the inner and outer membranes. When the amount of biogas in the inner membrane decreases, the air supply device is started to replenish air to the outer membrane to reach the design pressure of the biogas in the inner membrane. When the amount of biogas increases, the inner membrane stretches normally, and the excess air in the outer membrane is discharged through the pressure regulating device, so that the biogas pressure is always constant at a required design pressure.
[0003] At present, the more commonly used pressure stabilizing device is mainly composed of a blower and a pressure relief valve. The blower needs to supply air 24 hours a day. Its shortcomings are that it causes waste of manpower, waste of electricity, shortens the life of the blower and poses a safety hazard. Summary of the invention
[0004] The purpose of this equipment is to provide an automatic pressure stabilizing device for a biogas storage tank. The control system is composed of an air supply device, an air pressure regulating device, and an air pressure detecting device. It can make the air supply device run intermittently and automatically adjust the outer membrane pressure of the gas storage tank, thereby realizing the function of automatic pressure stabilization of the gas storage tank and the purpose of saving electricity.
[0005] The device relates to an automatic pressure stabilizing device for a biogas storage tank, which is provided with an air supply device, an air pressure regulating device, and an air circulation pipe at the bottom of the fermentation tank, an air inlet hole in the middle of the gas storage tank, and an air pressure detection device at the top of the gas storage tank. It is characterized in that the air supply device at the bottom provides the air source, the air pressure regulating device in the middle maintains the air pressure balance inside and outside the gas storage tank, and the air pressure detection device at the top realizes pressure regulation and monitoring.
[0006] The working process of the whole system is: set the high and low pressure values of the gas locker through the air pressure detection device. When the pressure of the outer membrane of the gas locker drops to the set low pressure value, the air supply device starts to supply air to the gas locker; when the pressure reaches the normal set value, the air supply device stops and the gas locker ends.

[0009] The device relates to an automatic pressure stabilizing device for a biogas storage tank, which is provided with an air supply device, an air pressure regulating device, and an air circulation pipe at the bottom of the fermentation tank, an air inlet hole in the middle of the gas storage tank, and an air pressure detection device at the top of the gas storage tank. It is characterized in that the air supply device at the bottom provides the air source, the air pressure regulating device in the middle maintains the air pressure balance inside and outside the gas storage tank, and the air pressure detection device at the top realizes pressure regulation and monitoring.
[0010] The air supply device is composed of a blower and a one-way valve. When the blower is turned on, the one-way valve opens; when the blower is stopped, the one-way valve closes.
[0011] The air pressure regulating device is composed of a pressure relief valve and a pressure gauge. When the pressure of the outer membrane of the gas storage cabinet is higher than the set pressure of the pressure relief valve, the valve opens and automatically releases air to the outside; conversely, when the pressure is lower than the set value, the valve closes.
[0012] The air pressure detection device can be set with two pressure alarm values, high and low.
