Organic rankine-type industrial waste heat integrated recovery device

Abstract

The invention relates to an organic rankine-type industrial waste heat integrated recovery device, which adopts a phase-changing heat exchanger technology based on an indirect heat exchanging way, and adopts organic medium to recover waste heat of combustible, explosive, toxic, corrosive or dust-contained high-temperature fluid or the waste water and waste vapor produced in the industrial production process. The organic rankine-type industrial waste heat integrated recovery device is characterized in that through the power generation of an organic rankine circulation power generator unit, the integrated recovery and high-efficient power generation of the waste heat resource of the entire system can be realized, and the heat circulating process of an oridinal system of the industrial production process is not influenced. The organic rankine-type industrial waste heat integrated recovery device not only can be used for recovering the waste heat of smoke of industrial kilns, power plant boilers and internal combustion engines, but also can be used for the integrated utilization of waste heat resource in chemical plants, and is remarkable in economical, social and environmental benefit.

Description

technical field [0001] The invention relates to an organic Rankine type industrial waste heat integrated recovery device, which specifically belongs 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 ...

Problems solved by technology

[0008] However, ORC technology also has its inherent disadvantages: since the organic working fluid may have the characteristics of flammability and explosion, when using the residual heat of flue gas to organize ORC in the tail flue of a boiler or industrial furnace, it is necessary to consider the dust in the flue gas, etc. The leakage caused by the wear and corrosion of the heat exchanger in the channel must be considered for the resulting explosion protection and the protection of the environment and the working place.
