Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 As shown, the biogas collection device 1 collects and stores the biogas produced by the fermentation of livestock manure in the farm, passes through the smoke pipe 2 into the biogas purification device 3, and then enters the gas internal combustion engine 5 through the first three-way valve 4, and the purified biogas drives the gas internal combustion engine 5 generates power, drives the water-cooled generator 16 to generate electricity through the output shaft 15, and provides electric energy for users.

[0029] The normal temperature water enters the generator heat exchanger 10 through the first water inlet 7 of the normal temperature water, and the generator cooling water enters the generator heat exchanger 10 through the generator cooling water inlet pipe 11 for heat exchange. Enter the jacket water heat exchanger 6, while t...

Abstract

The invention discloses a distributed combined cooling heating and power supply system based on biomass gas. According to the distributed combined cooling heating and power supply system based on the biomass gas, a power generator is driven through power generated by a gas internal combustion engine to generate electricity, and high-temperature smoke generated by the gas internal combustion engine is introduced into a smoke hot water type lithium bromide absorption chiller-heater at the same time for refrigerating and heating. On one hand, domestic hot water is prepared by combining water cooling of the power generator and water cooling of a cylinder sleeve of the internal combustion engine, and the system can also serve as a supplementary heat source for driving the absorption chiller-heater to prepare cold energy and heat energy. On the other hand, waste heat of the internal combustion engine can be used for constant-temperature fermentation of methane, and thus methane is produced continuously, stably and efficiently. According to the distributed combined cooling, heating and power supply system based on the biomass gas, gradient utilization of energy is achieved, the methane generated during fermentation of organic matter of biomass is fully recycled, and air pollution is effectively reduced.

Description

technical field [0001] The invention relates to a distributed combined cooling, heating and power generation system based on biomass gas. Background technique [0002] As a large agricultural country, my country has abundant biomass energy resources. The resources that can be used to produce biomass gas each year are equivalent to about 250 million tons of standard coal, which can convert about 199 billion cubic meters of biogas equivalent, equivalent to 120 billion cubic meters of natural gas, which is equivalent to my country's natural gas consumption in 2011 was 93% of 129 billion cubic meters. According to the total energy consumption in 2011 (3.48 billion tons of standard coal), the development of biomass gas will increase the proportion of China's gas energy consumption by about 7%. On the other hand, most farmers in our country still continue the habit of scattered farming. At present, there are 107 million pig breeding households in my country, 18 million dairy cows ...
