Problems solved by technology
[0003] However, the design mechanism of the heat transfer structure of the traditional waste heat recovery device is to directly mix the cold medium and the heat source of the waste steam for heat exchange, resulting in a large amount of impurities and bacteria in the waste steam being brought into the cold medium, which greatly increases the contamination of the cold medium. At the same time, there are disadvantages such as long heating time and poor heat transfer effect, which bring a series of processing difficulties to the production of enterprises and cause considerable economic losses.

The invention discloses a novel combined type waste heat recover. The novel combined type waste heat recover comprises a cavity which is divided into a washing cavity body and a heat exchanging cavity body through a partition wall. A washing water inlet is provided with a spraying device, and a water spraying plate is arranged on the inner wall of the washing cavity body. A refrigerant inlet of the heat exchanging cavity body is provided with a distributing device, a heat exchanging pipe vertically placed is arranged in the heat exchanging cavity body, and the heat exchanging cavity body and the washing cavity body are communicated through an opening to form a compact combined structure integrating washing and heat exchanging. In the heat exchanging process, the distributing device enables a refrigerant medium to form a refrigerant liquid film on the heating surface, high heat transfer efficiency is guaranteed, meanwhile, waste gas is washed before entering the heat exchanging cavity body and exchanges heat fully and indirectly with the refrigerant medium, and therefore the quality of the refrigerant medium is guaranteed thoroughly. In addition, the washing process of the waste gas is the preheating process of the refrigerant medium, so that heat energy in the waste gas is used fully and completely.
Description
technical field [0001] The invention relates to the technical field of energy recovery, in particular to a novel composite waste heat recovery device. Background technique [0002] In the fields of grain deep processing industry, fermentation industry, food industry, paper industry, light chemical industry, chemical industry and other fields, the waste steam (waste heat) discharged from the production section is recovered, so as to heat the cold medium required by the production process To process indicators, to completely or partially replace boiler steam, can achieve the purpose of "energy saving and consumption reduction" of enterprises. [0003] However, the design mechanism of the heat transfer structure of the traditional waste heat recovery device is to directly mix the cold medium and the heat source of the waste steam for heat exchange, resulting in a large amount of impurities and bacteria in the waste steam being brought into the cold medium, which greatly increas...
