Kalina type industrial waste heat integrated recovery device

Abstract

The invention relates to a Kalina type industrial waste heat integrated recovery device. Phase change heat exchanger technology based on an indirect heat transfer method is adopted, ammoniacal liquor mixture is adopted to recover combustible, explosive, poisonous, corrosion high temperature fluid or the high temperature fluid containing dust and recover waste heat of waste water and exhaust steam produced in industrial processes. Electricity is generated through a Kalina cycle power unit so that integrated recovery of residual heat resources and high-efficient power generation of the whole system is achieved, and thermodynamic cycle processes of an original system in the process of industrial production are not affected. The Kalina type industrial waste heat integrated recovery device not only can be used for recovering the waste heat of the exhaust gas in an industrial furnace, a utility boiler, an internal-combustion engine and the like, but also can be used for integrated utilization of the residual heat resources in a chemical plant. The Kalina type industrial waste heat integrated recovery device has remarkable economic, social and environmental protection benefits.

Description

technical field [0001] The invention relates to a Karina type industrial waste heat integrated recovery device, specifically belonging to the technical field of energy saving and environmental protection. Background technique [0002] Industrial production processes such as power plant boilers, industrial boilers, industrial furnaces and chemical plants will produce waste gas, waste water, waste steam, waste residue, etc., which contain a large amount of unused heat. For example, a large amount of flue gas is emitted during the production process of a power plant boiler, and there is a lot of heat that can be recycled; during the operation of the power plant boiler, continuous and regular sewage discharge must be carried out to ensure that the water quality of the boiler meets the safety requirements. At the same time, the oxygen in the boiler feed water must be Remove to avoid corrosion of the boiler system. At present, the thermal deaerator is the preferred technology for...

Problems solved by technology

[0008] The Kalina cycle power generation technology mentioned above also has its inherent disadvantages: For example, ammonia is flammable, explosive and toxic. When using the waste heat of flue gas to organize Kalina cycle power generation in the tail flue of boilers or industrial furnaces, it must To consider the leakage caused by dust in the flue gas caused by wear and corrosion of the heat exchanger arranged in the flue, it is necessary to consider the resulting explosion protection and the protection of the environment and working place; the ammonia-water mixture as the working medium Karina cycle, ammonia in ammonia water is a flammable, explosive, toxic medium
