Non-contact infrared radiation system

Abstract

The invention discloses a non-contact infrared radiation system. The non-contact infrared radiation system comprises non-contact infrared emitters, an outer casing and a support mechanism, wherein each non-contact infrared emitter includes a mixing part, a compression part and a combustion part; the outer casing includes a sealed chamber, a cooling chamber and a combustion chamber; the mixing part is arranged in the sealed chamber; the compression part is arranged in the cooling chamber; the combustion part is arranged in the combustion chamber; the support mechanism comprises a frame body, a combustion-supporting blower, a cooling blower and a proportioning valve; the cooling blower is connected with a cooling air inlet; the combustion-supporting blower is connected with an air blast inlet; and the proportioning valve is connected with the combustion-supporting blower and a combustion gas supply pipeline, and controls the combustion gas output power of the combustion gas supply pipeline according to the wind pressure blown by the combustion-supporting blower. The non-contact infrared radiation system improves power and efficiency of radiation combustion. The non-contact infrared radiation system realizes combined usage of a plurality of non-contact infrared emitters, and overcomes the problem that a ceramic oversheath of a fire needle can be cracked after being heated, thus prolonging the service life of the fire needle and improving stability of work.

Description

technical field [0001] The invention relates to the technical field of industrial heating, in particular to a non-contact infrared radiation system applied to industrial heating and drying. Background technique [0002] With the advancement of technology, the use of infrared radiation to evaporate and dry materials has gradually become a common technology in the field of industrial heating. Compared with air convection drying, this technology has the advantages of low energy consumption and good drying quality. [0003] In the prior art, gas infrared radiation generators mainly include: a forward radiation burner in which an infrared radiation source radiates materials from bottom to top and a side radiation burner in which infrared radiation originates from left and right side radiation materials. However, there are few reverse gas infrared radiators in which the radiation source radiates materials from top to bottom. In practice, the material to be processed is usually p...

AI Technical Summary

Problems solved by technology

The problem with this technical solution is that in order to ensure the proportion of air in the mixed gas, the amount of gas entering through the low-power gas inlet is not large, resulting in low power of infrared radiation

In addition, in the existing reverse gas infrared radiation generator, there is also the problem that the ignition needle of the ignition part is not well sealed, and it is easy to leak air and cause ignition failure; the infrared radiation source is a heated metal mesh, resulting in uneven infrared radiation ; After long-term processing, the water vapor generated on the surface of the material affects the combustion efficiency, and the ratio of air to combustible gas in the combustible mixture is difficult to control and many other problems.
