Abstract

The invention provides a heat exchange device capable of realizing combustion waste heat utilization. The heat exchange device comprises a heat exchange core and a casing; the heat exchange core is arranged in the casing; an upper header and a lower header are formed by the space between the heat exchange core and the casing; the casing comprises an upper casing and a lower casing; the upper casing comprises an upper casing front frame type baffle and an upper casing back frame type baffle which adopt identical structures; semi-circular holes penetrating through baffles are formed in middle areas of the upper parts of upper baffles; the upper baffle of the front frame type baffle is transversely placed at the front end of the heat exchange body upper casing and the front end of the heat exchange core and is fixed on the inner side of the heat exchange body upper casing; and side baffles of the front frame type baffle are located at the back part of the upper baffle of the front frame type baffle as well as the left side and the right side of the heat exchange core. With the heat exchange device, the baffles and flow guide plates are arranged on the heat exchange body upper casing and the heat exchange body lower casing, so that the thermal load of the heat exchange core is reduced while the heat exchange temperature difference is increased.

Description

technical field [0001] The invention belongs to the field of heat exchange, and in particular relates to a shell-and-tube heat exchange device for waste heat utilization. Background technique [0002] In the past ten years, due to the shortage of energy sources, with the further development of energy conservation work. A variety of new, energy-saving and advanced furnace types are becoming more and more perfect, and the use of high-quality insulation materials such as new refractory fibers has significantly reduced the heat dissipation loss of the furnace. The advanced combustion device is used to strengthen the combustion, reduce the amount of incomplete combustion, and the air-fuel ratio tends to be reasonable. However, the technology of reducing the heat loss of flue gas and recovering the waste heat of flue gas is still not progressing fast. In order to further improve the thermal efficiency of the kiln and achieve the purpose of saving energy and reducing consumption,...
