A new heat exchanger structure of gypsum board

Abstract

The embodiment of the invention discloses a gypsum board novel heat exchanger structure. The gypsum board novel heat exchanger structure comprises a heat exchange air box and a transition air box. A smoke outlet and a smoke inlet are formed in the left side and the right side of the heat exchange air box separately, an auxiliary heat exchange assembly is further arranged in the heat exchange air box, flow heat exchange assemblies are arranged on the upper side and the lower side of the auxiliary heat exchange assembly, the flow heat exchange assemblies penetrate through the heat exchange air box to be connected with the transition air box, and air pipes are connected to the sides, away from the transition air box, of the flow heat exchange assemblies. Through the arranged auxiliary heat exchange assembly, part of high-temperature smoke can be separated through an arranged transmission assembly to be directly exhausted out of the rear side for heat exchange, the problems that as heat isexcessively concentrated at the position of the smoke inlet, air in heat exchange pipes on the rear side cannot be effectively subjected to heat exchange can be avoided, the heat exchange pipes in the heat exchange assembly are of V-shaped structures, the sharp ends of the heat exchange pipes face the smoke inflow direction, the force bearing directions of the heat exchange pipes during heat exchange can be changed, and the heating anti-deformation capacity of the heat exchange pipes can be greatly improved.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of heat exchangers, in particular to a new structure of a gypsum board heat exchanger. Background technique [0002] During the drying process of the gypsum board, the air-air exchange technology is used to heat the cold air in the hot air pipe through the hot smoke in the heat exchanger equipment, thereby heating and drying the wet gypsum board to achieve a uniform and stable drying effect. During the use of the heat exchanger, due to the high temperature of the inlet smoke of the heat exchanger, there are often problems such as welding deformation of the welding joint between the windward plate and the orifice plate due to heat. Breaking, blowing of the bellows and air leakage seriously affect the heat exchange efficiency, resulting in waste of heat energy, which violates the purpose of energy conservation and environmental protection. Production will cause the temperature of the...

Problems solved by technology

[0003] To this end, the embodiment of the present invention provides a new type of heat exchanger structure for gypsum boards. By setting it in the auxiliary heat exchange component, part of the flue gas that has not been heat-exchanged can directly enter the rear heat exchange component for heat exchange. Heat exchange can evenly distribute part of the high-temperature flue gas, so that the temperature of the entire heat exchange device can be more evenly distributed, and with the set V-shaped heat exchange tube, it can solve the problem that the temperature is too concentrated in the prior art, which is easy to cause the heat exchange tube to open. The problem of low welding life
