Biogas is a kind of combustible gas produced by various organic substances through the fermentation of microorganisms under the isolation of air (reducing conditions) and at a suitable temperature and pH value. Biogas belongs to secondary energy and is a renewable energy. Biogas is not only easy to obtain, but also has no pollution after burning, which not only solves the source of household fuel, but also reduces the burning of fossil fuels, saves resources and reduces environmental pollution. As a big energy consumer in China, the development and utilization of new energy is of great significance to the sustainable development of the national economy. With the rapid development of rural social economy, rural energy consumption is also increasing. In this context, biogas resources as a The development and utilization of new energy with great application prospects is an effective measure to solve the problem of rural energy supply under the situation of energy shortage, and its development has been paid more and more attention by the country. With the support of the central government's policy guidance and capital investment, the scale of China's biogas industry has shown a trend of increasing year by year, especially the number of household biogas digesters has increased significantly, and has become the main force of the biogas industry.

At present, there are various biogas production systems in China, and the technology is becoming more and more mature and intelligent. However, due to the unstable average gas production of the biogas tank, the pressure of the biogas tank will be unstable, and it will not save energy. Sometimes it is necessary to have someone on duty , Monitor the pressure of the biogas tank. The existing intelligent monitoring system is costly and cannot be promoted. If the pressure of the biogas tank is unstable, it will not be able to carry out ultra-long-distance transportation, and it will bring hidden dangers to the safety of users.

In order to achieve the above object, the technical scheme of the utility model is:

An intelligent gas supply system for a biogas project, characterized in that the system includes a control cabinet, a booster, and a buffer tank, wherein the booster is arranged in the control cabinet and is integrated with the control cabinet, and the inlet of the booster It is connected with the purification module, the outlet is connected with the buffer tank, and the connecting pipe between the supercharger and the buffer tank is provided with a check valve, and the control cabinet is provided with an operation panel and a pressure gauge. After the biogas purified by the purification module is pressurized by the supercharger, it enters the buffer tank through the one-way valve. The gas outlet of the buffer tank is connected to the external centralized gas supply pipeline. The press enters the buffer tank and cannot return to the booster from the buffer tank.

Further, a pressure sensor is installed on the buffer tank, and the pressure sensor is connected to the control cabinet. The pressure sensor is used to monitor the biogas pressure in the buffer tank. When the pressure value is normal, the booster works normally. When the pressure value is not Normally, the control cabinet stops the supercharger and drives the alarm system to prompt the operator to make adjustments.

Further, an air pipeline is arranged on the top of the buffer tank, and the air pipeline is connected to the pressure gauge on the control cabinet, and the real-time pressure value in the buffer tank can be displayed through the pressure gauge on the control cabinet, which can be cooperated with the pressure sensor for double monitoring. Biogas pressure in the buffer tank.

Compared with the prior art, the structure of the biogas engineering intelligent gas supply system provided by the utility model is different. The system can stably control the biogas pressure in the buffer tank, provide stable gas supply pressure for subsequent biogas users, and monitor the buffer tank in real time. The internal biogas pressure ensures that the pressure in the biogas tank is within the normal range. When the pressure of the biogas tank is within the abnormal range, the control cabinet will intelligently control the supercharger to stop working and start the alarm program at the same time. The size of the biogas pressure in the tank starts or stops automatically, and the one-way valve in this system can prevent the biogas backflow in the buffer tank, which is more safe and reliable. The utility model realizes the intelligent control of biogas transportation, makes the biogas constant and stable, unattended, ultra-long-distance transportation, 24-hour uninterrupted gas supply, safe gas consumption for users, energy-saving and reliable.
