Description
Technical field
A kind of curing oven heating system is the utility model is related to, more particularly, to a kind of artificial quartz stone plate curing oven
With heating system and curing furnace heating system.
Background technology
Curing oven refers in electronics industry and other various industries, in order to reinforcing material with reference to stress and use plus
The container that hot systems are implemented to resin solidification and the production technology of drying.Heating system is indispensable important dress in curing oven
Put, concern curing oven total quality and operating efficiency.With scientific and technological progress and industry development, the existing curing oven species in market is numerous
It is more, curing furnace and metal-cured stove can be divided into by its action mode, wherein curing furnace heating system is because of Jie of heating
Matter difference can be divided into circulated air heating and heat-conducting oil heating, as the term suggests respective heat transfer medium is respectively air and conduction oil,
Circulated air heating can be divided into fuel oil stove heat and combustion gas stove heat again according to heating comburant is different, lead to first in closed furnace box
Cross naked light by air heating reach predetermined temperature after, air-introduced machine work hot-air is drawn through in pipeline to baking oven, fire
Oil oven, gas furnace can be divided into again to be directly heated and indirectly heat, combustion chamber air inlet communicate with air, and gas outlet connects with air-introduced machine
Connect, directly air heating is blown into curing oven by air-introduced machine by pipeline in combustion chamber and is referred to as directly heating；In combustion chamber
Provided with pipeline, open firing ventilation shaft indirectly heat air, pipeline couples with air-introduced machine, is blown into admittedly by pipeline by air-introduced machine
Change and be referred to as indirectly heat in stove.
It is the main heat form of existing curing oven by open firing formula wind circulating system, but due to fuel qualities not
One, purity not enough, mixed with impurity, What is more adulterates, insufficient due to burning, and influences temperature during burning, or even have
Black smoke or sharp aroma and pernicious gas produce, and are directly blown into by air-introduced machine in curing oven, cause product matter in curing oven
Amount is affected, and with sharp aroma or oily taste, therefore needs to increase waste gas, tail gas discharge system on curing oven, by useless, tail gas
Discharge is aerial to cause atmosphere pollution, and greenhouse effects aggravate, or increase exhaust treatment system, it is necessary to increase corresponding environmental protection equipment, into
Originally greatly increase；Temperature control is difficult, needs constant holding, method one after reaching predetermined temperature in general curing oven：Pass through control
Total amount of combustible control solidification in-furnace temperature processed, but due to combustible factors（The factors such as fuel oil quality, gaseous-pressure）It is bad
Control causes flame velocity, flame size different, causes to solidify in-furnace temperature into wavy change, causes solidfied material nexine
Outer ply stress is different, influences the quality of product；Method two：By controlling Boiler pressure control to solidify in-furnace temperature, but there is intake
CO is also easy to produce less than amount of oxygen burning is insufficient needed for burning, peripheral equipment operator causes security threat to burner.Indirect type
Heating is direct-fired spin-off, is indirectly heated air by setting pipeline in heating, and the warm wind into curing oven is cleaning
, the gas of smoke dust and smell, but the drawbacks of heat exchange thermal losses be present, do not meet the policy for saving energy resources.
No matter there are waste gas, soot emissions in oil burner heating system or gas furnace heating system, it is poorly operated easily produce it is harmful
Gas, it is unfavorable for environmental protection.For production safety, curing oven is typically separated with combustion furnace, is easy to directly observation burning
The dynamic of stove, air-introduced machine are placed between combustion furnace and curing oven, and warm wind is pumped to curing oven, pipeline by air-introduced machine by pipeline and passed
Thermal loss is will also result in when sending.Because combustion furnace individual is huge, it is built in curing oven and takes curing oven inner space significantly, make
Free space reduces inside curing oven, in order to meet yield, can only increase the inner space of curing oven, inner space actually increases
Institute's calorific requirement is more, and resource consumption is bigger, and fuel oil and the presence safety problem of combustion gas are even more unmanageable in built-in curing oven；
Combustion furnace must be provided with air inlet and Waste gas outlet, and pipeline is various, cause should the curing oven of good seal easily occur
Warm problem is rushed down in gas leakage.
The content of the invention
To solve the problems, such as that existing curing oven heating system is present, the utility model provides a kind of reasonable in design, operation side
Just, the high new-type curing oven product of security performance.
The utility model use scheme be：A kind of formula curing furnace heating system, including positioned at curing oven casing
