Problems solved by technology

[0005] 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 Remaining 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

Abstract

The present invention discloses a reversed combustible gas radiation generator comprising a combustible gas injection portion, a combustion portion which is provided with an air-guiding device on an external wall thereof, the air-guiding device including an air-inducing port which faces towards the ground for discharging air, the air-inducing port being provided with an inclined angle extending outwardly in a perpendicular direction thereto. The reversed combustible gas radiation generator herein provides a radiation generator capable of realizing reversed combustible gas, and reduces interference effect of the moisture-removal and transverse dry air flow on the radiation field.

Description

technical field [0001] The invention relates to the field of industrial heating and drying, in particular to a reverse gas radiation generator used in industrial heating and drying. Background technique [0002] In the prior art, the traditional reverse gas infrared radiation generator includes a gas injection device, a combustion device and a radiation area. The gas burns in the combustion part to generate infrared radiation to dry and heat the workpiece in the radiation area. The dry air is blown in to achieve the technical effect of blowing the waste gas produced by the combustion of the gas and the water vapor transpired from the surface of the heated workpiece away from the radiation area. [0003] According to the inverse quadratic law of radiation, the radiation intensity of the radiation of the point light source of the radiator is inversely proportional to the square of the radiation distance, and the radiation energy expands in a spherical shape in space. The air ...
