Abstract
The utility model provides a microwave reaction device, which comprises a reaction vessel and microwave generators, wherein the microwave generators are arranged at the periphery of the reaction vessel and are arranged around one circle of the reaction vessel. The microwave reaction device can be suitable for large-capacity material reaction, and microwaves can be more uniformly distributed on materials, so that the heating temperature of the materials is more uniform, and the phenomenon of local overheating cannot be generated. In addition, as the number and the position of the microwave generators are reasonably distributed, the fewest generators and the minimum power are used while the excellent heating effect is achieved.
Description
Technical field
The utility model relates to a kind of chemical plant installations, particularly utilizes microwave to realize the reaction unit of heating.
Background technology
Often use heater in the commercial production, traditionally, heating realizes through for example electricity, fuel, conducts heating container through heat, and then is the content heating in the container.This traditional approach must also have the heat radiation of heating back container, the thermal diffusion of fill container outer wall etc. in addition earlier with the container heating, therefore causes the great amount of heat loss.
Microwave can pass insulating materials such as glass, pottery, plastics, but can consumed energy, but microwave can't pass metal, and it runs into metal and just reflects.Based on this, reactant is held in place in the water conservancy diversion container of rustless steel container, through microwave alternation (for example power setting is 2450 ± 25 MHz), then the polarity of the molecule in the heated material also changes thereupon.In variation, molecule will produce a large amount of frictional heats, thereby reach the purpose of heating.In heating process, accomplished the transformation of energy of electromagnetic energy thermotropism.Microwave is instantaneous heat temperature raising to dielectric material, and only has material to absorb microwave with power conversion in the container, does not therefore have thermal loss.
For example; China utility model patent CN 202009509 U promptly disclose a kind of microwave heating equipment; It comprises the reactor of a metal shell, is provided with the material stream passed pipeline that microwave generator and insulating materials are processed in the reactor, and the two ends of material stream passed pipeline pass reactor.In this scheme, material is directly heated by microwave, and microwave acts directly on and promotes molecular motion to produce heat energy on the molecule of material, has improved firing rate greatly and has shortened the reaction time.
Again for example; China utility model patent CN 102258970 A disclose a kind of microwave reaction kettle; It utilizes the microwave energy transmission technology and passes through Bomi sealed knot bundle and combine, in the agitated reactor side additional one have the Bomi envelope be total to more can the microwave working cavity, make its suitable microwave transmission and utilization; Utilize this microwave working cavity to import microwave, inhale the ripple material in the radioreaction still and heat or excite chemical reaction.
Yet existing microwave reaction device many places are in the experiment rank, and power is little, capacity is also little; Therefore quantity and the position arrangement for microwave generator do not have too many requirement; Make that microwave generator is usually located at container top or away from the side of container, when agitated reactor was used for large-scale production, capacity increased greatly; Even reach several hectolitres, when going up kilolitre; Be positioned at the bottom that microwave that the microwave generator at top sends is difficult to arrive container, perhaps more generally, the microwave that is sent arrives the amount of container bottom far below near the amount of radiation the microwave generator; Cause the suffered amount of radiation of material at container bottom, centre, top not wait, cause the material heating inhomogeneous.
Summary of the invention
In view of this, the utility model provides a kind of improved microwave reaction device, and it can adapt to jumbo material reaction, and the more even distribution of microwave on material, thereby the heating-up temperature of material is more even, the phenomenon of hot-spot can not occur.In addition, owing to reasonably disposed the quantity and the position of microwave generator, can when using minimum generator, minimum power, reach excellent heats.
A kind of microwave reaction device that the utility model provides, it comprises reaction vessel and microwave generator, it is peripheral that wherein said microwave generator is arranged on said reaction vessel, and be provided with around said reaction vessel one circle.
In an embodiment of the utility model, said microwave generator is provided with around a circle at said reaction vessel middle part.
In an embodiment of the utility model, the power of each of said microwave generator is 2KW to 3KW, for example 2KW, 2.5KW or 3KW.Preferably, each of said microwave reactor all has identical power.
In an embodiment of the utility model, said microwave generator is 4 to 10, and preferably, said microwave generator is 6 to 8, for example 8.
In an embodiment of the utility model, the volume of said reaction vessel is 10L to 1000L, is preferably 200L to 800L, for example 500L.
In an embodiment of the utility model, said reaction vessel is through can passing through the material of microwave, and for example plastics are processed.
The microwave reaction device that the utility model provides; It is provided with the circle of a plurality of microwave generators around the reaction vessel outside; Preferably be arranged on the position near the middle part of reaction vessel, make the top of microwave arrival container and the amount of bottom trend towards equalization, thereby the more even distribution on material; The phenomenon of hot-spot can not appear in the heating-up temperature of material thereby more even.In addition, microwave generator is arranged on the outside of reaction vessel, the installation and removal of more convenient microwave generator, and in prior art, use lateral guide to go into the technology of microwave, structure is simple more and efficient is higher.
Description of drawings
Fig. 1 is the structural representation of microwave reaction device of an embodiment of the utility model.
Fig. 2 is the cross-sectional view of the microwave reaction device of Fig. 1 along the A-A line.
The specific embodiment
Describe the specific embodiment of the utility model in detail below with reference to accompanying drawing.Should be understood that these accompanying drawings and detailed description only are the detailed as far as possible exemplary elaborations to the utility model principle, are not to be the restriction to the utility model protection domain.In the utility model, the figure number at place when this Reference numeral of the leftmost numeral of Reference numeral occurs for the first time, and similar characteristic is represented with similar Reference numeral.
With reference to figure 1, it has shown the structural representation of the microwave reaction device among the embodiment of the utility model.In this example, this microwave reaction device is a microwave reaction kettle 100, and it comprises reaction vessel 102 and the microwave generator 104 that is arranged on reaction vessel 102 outer surfaces.The height of microwave generator 104 is in the middle part of reaction vessel 102 approximately.Certainly, according to the capacity of reaction vessel 102 internal reaction things, also can microwave generator 104 be arranged on different height.
