Absorption type refrigeration and power combined circulating system

Abstract

The invention relates to a low temperature heat energy recycling technology and discloses a combined circulation system of absorption refrigeration and power. The combined circulation system comprises heat source, a circulating device and a circulating working medium. The combined circulation system is characterized in that the circulating device comprises a rectifier, a condenser and a steam generator which are connected with the rectifier. A superheater, a turbine, an absorber, a circulating pump and a forewarmer are in turn connected with the superheater of the steam generator. A throttle valve and an evaporator are in turn connected wit the condenser. A generator is connected with the turbine in the same shaft. The power is exported by the generator. The forewarmer is connected with the rectifier. The heat source in turn passes through the super heater, the steam generator and the forewarmer. The evaporator is connected with the absorber, and at the same time the cold energy is exported by the evaporator. The circulating working medium is the mixture of ammonia.

Description

technical field [0001] The invention relates to low-temperature heat energy recycling technology, in particular to an absorption refrigeration and power combined cycle system. Background technique [0002] In the process of industrial production, such as the production of industrial products such as cement, sulfuric acid, and glass, a large amount of waste heat resources are discharged into the environment in various forms, causing serious energy waste and environmental pollution. In addition, there are abundant geothermal resources and solar energy in nature. Therefore, the recovery of industrial waste heat and the utilization of renewable energy have important practical significance and engineering application value for alleviating environmental pollution and reducing the consumption of fossil fuels. At present, the steam power cycle system is widely used in the recovery of industrial waste heat. The steam absorbs heat at a fixed temperature, resulting in relatively large...

AI Technical Summary

Problems solved by technology

At present, the steam power cycle system is widely used in the recovery of industrial waste heat. The steam absorbs heat at a fixed temperature, resulting in relatively large irreversible losses in the heat exchange process, and the recovery efficiency of low-temperature waste heat is low. In addition, the steam power cycle can only output power, and It cannot output electric energy and cooling capacity at the same time, and cannot meet the various energy needs of users
