Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments.

Principle of microwave drying equipment: microwave refers to electromagnetic waves having a frequency of 300 mhz to 300 ghz. The water molecules in the heated medium material are polar molecules. Under the action of fast changing high frequency electromagnetic field, the polarity orientation will change with the change of the outer electric field, resulting in molecular motion and mutual friction effect. At the moment, the field energy of the microwave field is converted into the heat energy in the medium, so that the temperature of the material is raised, and a series of physical and chemical processes such as thermalization, puffing and the like are generated, thereby achieving the aim of microwave heating and drying.
The embodiment of the application provides a high-efficiency and energy-saving slasher hot air drying system and a heating furnace, and aims to solve the problem that heat loss caused by heating cold air by an electric heating pipe in the related art is large.
Referring to fig. 2 and 3, a heating furnace includes a sealed box 1, an air duct 2, a plurality of microwave absorbing and heating members 3, and a plurality of microwave generators 4; the microwave generator 4 adopts a civil microwave generator to form a cluster waveguide array.
Wherein, the sealed box body 1 is hollow and is provided with an air inlet and an air outlet; the air duct 2 is arranged in the sealed box body 1, and the two ends of the air duct are respectively penetrated with the air inlet and the air outlet.
The microwave absorbing and heating parts 3 are arranged in the air duct 2 and distributed along the length direction of the air duct 2, and a honeycomb type air duct is arranged on the microwave absorbing and heating parts 3 in a penetrating manner; the microwave generators 4 are arranged on the inner wall of the sealed box body 1 and are positioned outside the air duct 2. The microwave absorbing heating element 3 is made of honeycomb ceramic components made of microwave absorbing heating materials. The microwave absorbing and heating material can generate high temperature after absorbing microwave, and the highest temperature can reach 1300 ℃ according to the difference of material quality and microwave density. The material is used for manufacturing honeycomb ceramics, and air passes through the fine holes to heat the air, so that high-temperature gas enough for producing sizing is generated and used for a drying cylinder.

Compared with the mode that the traditional microwave heating device directly heats air, the traditional microwave heating device can heat air only by a certain amount of moisture in the air, the more the moisture is, the better the heating effect is, but the influence of oxidation corrosion is larger when the air with the moisture is heated. Therefore, the indirect heating mode of the heating furnace does not need to ensure that a certain amount of moisture exists in the air, and the heating effect is good; therefore, the traditional heating mode is replaced, energy is saved, the environment is protected, and the market demand direction is adapted; compared with the traditional mode (coal-fired natural gas and commodity steam), the heating furnace can greatly reduce the energy consumption in unit yarn production, reduce the production cost, and has reliable operation, simple and convenient maintenance and low maintenance cost.
