Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, in particular to a high-efficiency heat exchange device. Background Art

[0002] In existing enterprises that use fuel combustion to provide heating, their exhaust emissions usually contain a high amount of heat. In order to comply with the emission requirements of the environmental protection department, a cooling device is usually used to cool down the exhaust gas. This cooling device is a cooling tower or air-conditioning equipment. However, both of the above methods have disadvantages, which are reflected in the following aspects: 1. Cooling towers and air-conditioning equipment generally treat clean exhaust gas. For example, the exhaust gas of coal-fired enterprises usually contains a high amount of dust, which cannot be directly transported to cooling towers and air conditioners. High-temperature resistant dust reduction and dust removal equipment must be equipped, resulting in an increase in equipment costs; 2. When cooling the exhaust gas, the existing cooling towers or air-conditioning equipment cause a waste of energy, which more or less promotes the occurrence of the greenhouse effect, which is detrimental to the environment.
