Abstract

The invention relates to a heat exchanger, in particular to a boiler heat exchanger for asphalt mixing equipment and belongs to the technical field of heat exchangers. The boiler heat exchanger comprises a housing and a plurality of heat exchange tubes. The upper end of the housing is provided with an air outlet; the lower end of the housing is provided with an air inlet. The upper and lower ends of the inside of the housing are provided with an upper baffle and a lower baffle respectively; the heat exchange tubes are fixed between the upper baffle and the lower baffle; the heat exchange tubes allow the air outlet and the air inlet to be connected to form air passages. The boiler heat exchanger is simple, compact and reasonable in structure, allows water to be heated by making effective use of hot air discharged by a boiler of the asphalt mixing equipment, allows the cold water to be heated without polluting the environment and has functions of energy saving and environment protection.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a boiler heat exchanger of asphalt mixing equipment, belonging to the technical field of heat exchangers. Background technique [0002] In the prior art, the hot gas discharged from the boiler used in the asphalt mixing plant is generally directly discharged into the external environment, which not only wastes energy, but also affects the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a boiler heat exchanger, which can effectively use the hot gas discharged from the boiler of the asphalt mixing plant to heat water, and play the role of energy saving and environmental protection. [0004] According to the technical solution provided by the present invention, the boiler heat exchanger includes an outer casing and a heat exchange tube, and the characteristics are as follows: the upper end of the oute...
