Description
Technical field
The present invention relates to a kind of rubber regeneration heating means and device, the heater (as digester) that uses in producing in particularly a kind of rubber industry.
Background technology
Process equipment mainly still adopts heat-conducting oil furnace (comprising that hand burns formula heat-conducting oil furnace and coal heat-conducting oil furnace) and far infrared (resistance-type) mode of heating in the rubber industry production at present.(digester of heat-conducting oil heating mode generally is provided with chuck)
1, hand burning formula heat-conducting oil furnace and coal furnace all are to adopt thermal-flame to give metallic conduit in the stove thermal energy transfer, after metallic conduit is heated heat energy is conducted step by step to conduction oil mobile in the pipe again, high temperature heat conductive oil is injected in the chuck of rubber heater by the circulatory system, thereby realizes that thermal energy transfer reaches the production purpose;
2, no matter be that heating of employing handwarmer or coal furnace heating are to adopt the external mode of heating substantially.The metal pipe-wall temperature is generally all at 800 ℃-1300 ℃ in the stove, and the conduction oil temperature that we need generally (is used the conduction oil of different labels according to needs of production about 250 ℃-350 ℃, its temperature ability to bear is also different), so conduction oil is under long term high temperature, it is badly damaged, quicken conduction oil knot charcoal and aging, influence useful life, can only use continuously about 3 years and just must change or regeneration; And such technology mode certainly will cause enterprise to increase the quantity of stocking of conduction oil, for example: 6 cubic metres digester needs 1.5 tons of conduction oils in the reclaimed rubber industry, if enterprise has many digesters and produces simultaneously, just must strengthen the power and the volume of heat-conducting oil furnace, perhaps just must dispose many heat-conducting oil furnaces and could guarantee that ordinary production needs, the own expense of adding conduction oil is higher, brings huge input waste to enterprise;
3, resistance-type heating also belongs to a kind of heat exchange pattern, and its working method is at first after the resistance-type device energized, and the resistance device self-heating passes to heated object to heat energy from outside to inside by contact then.Its efficiency of heating surface is low, usually have only 50% left and right sides heat to be used effectively, and there is very big thermal loss, compare the heat-conducting oil heating mode warm-up time and shorten to some extent, but non-uniform temperature, and the heated object surface temperature is higher, easily deform after working long hours, the resistance-type device is fragile, and energy consumption is relatively large, and later maintenance cost is higher.
Particularly point out that desulfurization is a master operation in the production of reclaimed rubber in the rubber industry, thereby desulphurization plant also is the main production equipment of reclaimed rubber enterprise.What China reclaimed rubber manufacturing enterprise generally used at present is the HTHP sulfur removal technology.The shortcoming that has highly energy-consuming, high pollution, device distortion, production cycle length etc.Though current external existing a lot of new production technologies are come out.Tired various reasons also is difficult to replace existing technology.
Summary of the invention
The purpose of this invention is to provide a kind of rubber regeneration electromagnetic-induction heating method and device, the invention solves prior art and exist: one, highly energy-consuming; Two, high pollution; Three, device distortion; Four, long problem of production cycle.
Rubber regeneration electromagnetic-induction heating method and device comprise heater (digester), electromagnetic generator, solenoid and power supply, and the heater outside is wound with some groups of solenoids, are connected to power supply again after solenoid is connected on the electromagnetic generator.
Rubber regeneration electromagnetic-induction heating method of the present invention and device also have following characteristics, comprise temperature sensor, the position of each group solenoid correspondence is equipped with temperature sensor on the heater sidewall, and the end of transducer is inserted in the inside of heater.
There is solenoid to be wrapped on the heater (1).
On heater, also has feeding mouth.
Outside at heater also is enclosed with insulation material.
Rubber regeneration electromagnetic-induction heating method of the present invention and device than former heat-conducting oil furnace formula and resistance-type heating, mainly have following several significant technical characterstic and advantage.
(1) fail safe is good. and simple and reasonable, maintenance, easy to operate.Owing to got rid of external firing equipments such as old-fashioned heat-conducting oil furnace, adopt the novel electromagnetic induction heater element, have the high advantage of the heat efficiency.In the use than heat-conducting oil furnace safety and reliability.Control instrument electrification in the production.Concentrate on control cubicle, reflect the parameters such as temperature in the production process at any time, easy to operate; And electromagnetic heating apparatus is provided with automatic safety devices such as overvoltage, overcurrent.Meet abnormal conditions in the production. just stop heating automatically.Guarantee production safety.Because the general structure advantages of simple, installation and maintenance are also corresponding simple and convenient.
(2) energy-saving and production-increase.The advantage of electromagnetic type heating means is to make the direct heating of rubber heater self, and the insulation material that heater packs outward can play the purpose of insulation, avoids thermal loss as far as possible, and heat efficiency height shortens the heating-up time greatly.And be not subjected to the temperature difference influence in season basically.Because quick heating has shortened the rubber production time, has improved the output of rubber.
(3) improve rubber regeneration production quality.Because due to the heat resistance of conduction oil, the heat conducting oil type heat temperature raising must be observed certain operational procedure, temperature, pressure control is very strict, can not be too high.And electromagnetic induction heating mode working temperature can be according to the needs of production flexible, its high temperature, high pressure controlled range be much larger than heat conducting oil type, thereby adapt to widely, and high pressure really reaches a high temperature, can satisfy different elastomeric material productions, improve the production quality of elastomeric material.
(4) reduce blowdown, environmental.The electromagnetic type mode of heating has thoroughly been got rid of the leakage of oil, water in the production, and waste oil, waste water are eliminated to the pollution of environment in the production process.Production environment purifies greatly, has created good working condition for a line production operation workman, has alleviated the pressure of manufacturing enterprise's environmental protection pollution treatment simultaneously greatly.
Should be noted that especially, rubber is China's starting late of reclaimed rubber industry particularly, the production technology of existing enterprise and equipment are still more backward, in view of the economic benefit of industry itself is limit, country or collective can not drop into relatively large fund and carry out large-scale technological transformation and introduction at no distant date.So rely on industry and domestic self technical force and fund, upgrade enterprise's production technology, progressively increase the technology content of reclaimed rubber industry, promote the technological progress of reclaimed rubber enterprise, make the technology of reclaimed rubber industry accomplish efficient, energy-conservation, economic, practical, be to revitalize China's reclaimed rubber industry, it is shaped up and grow in strength.
