Problems solved by technology

However, the design of the reverse gas infrared radiator needs to solve two technical problems: 1. Reverse combustion will cause the premixed gas to be poured from above the combustion plate, how to control the balance between the input speed of the premixed gas and the burning speed; 2. How to suppress the heat Conduct upwards to control the temperature of the gas infrared radiator to prevent the premixed gas from igniting and exploding inside the combustion plate
[0009] This technical solution has the following negative effects: 1. The speed of airflow input is far greater than the speed of combustion, and the mixing ratio of gas and air is difficult to control, resulting in incomplete combustion and large gas consumption; 2. Burner power Remains high, not suitable for materials that need to be heated and dried at low temperature
3. The source of infrared radiation is a heated metal mesh, resulting in uneven infrared radiation
The air flow blown in laterally has great damage to the high-temperature dry bulb radiation field, greatly weakening the radiation effect

Abstract

The invention discloses a reverse infrared radiation machining method for drying materials. Combustion air flow is injected into an air flow inlet in a gas ejecting mode, gas and combustion air form premixed gas, the premixed gas is ignited by an igniter to burn, cooling air is blown to continuously cool an ejecting pipe and the outer lateral wall of a burning portion, and materials pass through a radiation area below the burning portion to receive radiation generated by burning of pre-burning mixed air to achieve heating drying. An infrared radiator of reverse gas is achieved, the burning speed is also reduced, the method is applicable to materials heated and dried at a low temperature and the effects of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the fields of industrial heating and drying, in particular to a radiation processing method for realizing reverse combustion gas to generate infrared radiation to heat and dry materials. Background technique [0002] Utilizing the principle of thermal effect of infrared radiation on the resonance cracking of macromolecular water mass, it is a common technology in the field of industrial heating to evaporate and dry materials with infrared radiation. Compared with air convection drying, this technology has the advantages of low energy consumption and good drying quality. [0003] In practice, the generation methods of infrared radiation are mainly divided into two ways: electric heating ceramic plate radiation and electric heating infrared lamp tube. Both use electric energy to convert heat energy into secondary heating infrared radiation carrier. Among them, the electrothermal infrared lamp has the defects of easy short circu...
