Description
Technical field
The present invention relates to industry heating, dry field relates in particular to be applied to a kind of industry heating, in dry processing
Reverse infrared radiator.
Background technology
Using infrared ray to the fuel factor principle of macromolecular water body resonance cracking, material is steamed with infrared radiation
Dry processing, is the common technology in current industry heating field.This technology relative atmospheric convective drying has that low energy consumption, dry
High-quality advantage.
In practice, the production method of infrared radiation is broadly divided into:Electric ceramic plate radiates and two kinds of electric heating infrared fluorescent tube
Mode.Heat-energy secondary HEATING INFRARED is both converted into using electric energy and radiates carrier.Wherein, electric heating infrared fluorescent tube exists easy to be short
Road, damaged and with high costs defect;And electric radiation needs to convert electric energy, then the conversion of secondary consumption electric energy by chemical reaction
For heat radiation, energy causes more energy consumptions through multiple conversions.
10,000 kilocalorie heats are generated with electric radiation, institute's consuming electric power about needs to spend 12 yuan (by often 1 yuan of calculating of degree electricity).And such as
Change to directly generate the working method of heat radiation using combustion gas, generates 10,000 the consumed liquefied petroleums of kilocalorie heat and (press per kilogram
6.6 yuan of calculating) only need about 6 yuan.Obviously, it is more economical that heat radiation is generated in a manner of combustion gas.
In prior art, gas-fired infrared radiation generator includes mainly:Infrared emitter radiates from bottom to top
The positive radiant burner and infrared ray of material are originated from left and right sides to the antenna with side radiation direction burner of radiation material from radiating.And rarely have
Radiation source from top to bottom radiates the reverse Gas-fired Radiator in Municipal of material.In practice, usually put what material to be processed lay low
It sets on processing conveyer belt, the heating for receiving radiant burner by heating work region with transmission mode is dried.
For the positive gas-fired infrared radiator that infrared ray radiates from radiation source material from bottom to top:Radiation source and to be added
Barrier has conveyer belt, conveyer belt to bear the direct radiation of infrared ray between work material, and material to be processed is held indirectly across conveyer belt
Raying cannot achieve infrared ray and directly radiate, and heat drying efficiency is relatively low;And to infrared ray from radiation source by side transverse direction spoke
It penetrates for the gas-fired infrared radiator of material:For material far from radiation source, heat drying effect is undesirable.
Above-mentioned two can be solved by designing a kind of reverse Gas-fired Radiator in Municipal that radiation source from top to bottom radiates material
Technological deficiency.But it designs reverse Gas-fired Radiator in Municipal and needs to solve two technical problems:1. reverse combustion will cause pre-
Mixed combustion gas pours into above burner plate, how to control the input speed of pre-mixing gas combustion and the balance of burning velocity;2. how to inhibit
Heat conducts upwards, controls the temperature of gas-fired infrared radiator and prevents pre-mixing gas combustion from lighting and exploding on the inside of diffusion storehouse.
Reverse infrared radiator uses machinery air intake mode in the prior art, constantly from top to bottom with high power air blowers
Air stream is blasted, air stream drives combustion gas to burn in combustion front, heats metal mesh with flame, metal mesh is made to emit infrared waves.Drum
The air stream one side and combustion gas mixing that wind turbine blasts, form pre-mixing gas combustion, on the other hand from the cooling reverse Gas Infrared in inside
The metallic walls of radiator prevent tube wall temperature from spending high pre-mixing gas combustion of being lighted inside radiator and generate explosion.To ensure to cool down
Effect, the air stream blasted must have faster flow velocity.
There are negative interactions as described below for this technical solution:1. the speed of pre-mixing gas combustion input is far longer than the speed of burning
Degree, excess air is more, incomplete combustion, and heat utilization rate is low.2. burner rating is high, to needing low-temperature heat to dry
Material is not applicable.3. infrared emitter is the metal mesh heated, cause infra-red radiation uneven.
How to design it is a kind of not only having supported the infrared radiator of reverse combustion gas, but also reduce burning velocity, be suitable for low temperature
The material of heat drying, and the reverse gas infrared radiation generator of effects of energy saving and emission reduction can be reached, it is those skilled in the art
The work of initiative thinking should be played.
