Problems solved by technology

[0004] The current large-scale utilization of biomass is mainly for power generation and heat supply. The power generation methods include direct combustion power generation and gasification power generation. It is difficult to collect raw materials for direct combustion power generation, the efficiency is low, and its economy is poor
Conventional gasification power generation is mainly through internal combustion engines, which are difficult to achieve large-scale production due to poor stability. Biomass gasification gas turbine power generation has been widely used as an emerging technology. Because gas turbines have high requirements for gas quality, existing production The material gasification gas turbine technology mainly uses pure oxygen as the gasification agent. The gas generated by the gasifier is deeply purified through a complex purification system to obtain high-quality gas. The existing problems are: the operating cost of the air separation system is high, and the gas purification produces The phenol-containing wastewater is difficult to treat, which greatly restricts the promotion of technology

The refrigerating system comprises a carrier heating furnace, a high-temperature pyrolyzer, a pyrolyzer, a second-level condenser, a first-level condenser and the like, wherein an outlet of the carrier heating furnace is connected with an inlet of a cyclone dust collector; and an ash discharge pipe on the bottompart of the cyclone dust collector is connected with an inlet of the pyrolyzer. The production process comprises the steps of heating a carrier, pyrolyzing biomass, pyrolyzing tar, utilizing waste heat, purifying fuel gas, producing freeze water, producing hot water, generating power and the like. Through the matching connection of heat energy, the efficiency of the biomass energy can be maximallyutilized, and the advantage of high utilization efficiency is realized; and no tar or waste water is generated in a gasification power generation system, so that the reliability of system operation is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration utilization, and in particular relates to a refrigeration system and process based on biomass energy. Background technique [0002] Process production plants often have strict requirements on their internal temperature and humidity. Most of the temperature and humidity in process production plants are controlled by a centralized central air-conditioning system. The central air-conditioning system often requires dehumidification. To the low temperature, the water vapor in the air is condensed into a liquid state, and then the air is heated by hot water to realize the adjustment of temperature and humidity. The operation mode of the existing refrigeration system in the factory area is mainly the coordination of the refrigerator and the gas boiler, that is, the chilled water generated by the refrigerator is used for refrigeration, and the steam or hot water generated by the gas boiler is used f...
