Description
Technical field
The utility model patent relates to a kind of heating furnace cavity design, especially to the microwave tube furnace, belongs to advanced and makes and technical field of automation.
Background technology
Environmental problem is the hot issue that the current China and even the whole world are all paid close attention to.China is one of the most serious country of atmosphere pollution in the world.In the pollutants of 68 kinds of preferential controls that China environmental monitoring master station proposes, organic compound has 58 kinds, and the visible organic exhaust gas of administering is one of an atmospheric environment protection very part and parcel.The organic exhaust gas fecund is in industrial processes such as oil, chemical industry, printing and dyeing, bonding, coating, and the main feature of these organic exhaust gas is that low concentration, air quantity are easy to volatilization greatly and all.The concentration of these organic exhaust gas is generally less than 5000mg/m
3-, do not have the value of recycling mostly, but the harm of health and ecological environment do not allowed to ignore.Adopting traditional organic waste-gas purification method mainly is the organic exhaust gas that is used for purifying high concentration, and the organic waste-gas purification of low concentration is existed complex process, problem that operating cost is high.For example in the organic exhaust gas to the processing of bitumen flue gas; The method that present stage handles roughly has burning method, static method of trapping, absorption method, absorption process etc., but these methods all exist certain difficulty, and the imflammable gas that for example burns exists cost high; Resistance wire is easily broken; Problems such as heating and cooling are slow, and energy consumption is high, and is seriously polluted.To these problems; Sought out the method for another kind of processing; The method of microwave burning disposal bitumen flue gas, this method not only can expand to handles other industrial pollution gases, and is that national now green metallurgical, the ecological metallurgy of advocating has been opened up the new visual field.Microwave is rarely found in the application of incineration gases, and equipment still can not reach the requirement of handling gas, so this patent has proposed new improving one's methods and studying to its equipment.
In existing technology, the microwave tube furnace adopts the monoblock type fire door, and equipment is when the heating that is used for solid material and processing and gas burning experiment, and the suction ripple medium in the tube furnace often causes SR very big owing to there is not regularly placing, and internal-combustion is inhomogeneous.And when using thermocouple temperature measurement, thermocouple probe is blindly contact in tube furnace, and each is different for the different parts temperature of contact, can cause very big error to the ambient temperature measurement in the tube furnace.
Summary of the invention
The utility model relates to a kind of microwave tubular type furnace cavity; It is a kind of simple in structure that purpose is to provide; Can reduce the furnace cavity of SR, make tube furnace internal temperature homogeneous heating, and thermocouple is disorderly inserted the problem that data are disobeyed can improve thermocouple and survey the inside cavity temperature time.
The microwave tubular type furnace cavity of the utility model is formed structure such as Fig. 1, shown in Figure 2, comprises furnace chamber housing (1), suction ripple medium (2), thermocouple jack (3), furnace chamber inner housing (4), fire resistant heat preserving cotton (5), support ring (6), inhales ripple medium jack (7), thermocouple (8).
Microwave tubular type furnace cavity is to be embedded in furnace chamber shell body (1) inside by furnace chamber inner housing (4); Between furnace chamber inner housing (4) and the furnace chamber shell body (1) flame-proof thermal insulation material (5) is arranged; The furnace chamber inner housing is inlaid with support ring (6); Inhale ripple medium (2) and be arranged in the suction ripple medium jack (7) of support ring (6), it is thermocouple jack (3) that there is a circular hole at the center of support ring, and thermocouple (8) inserts thermometric from centre bore.(like Fig. 1, shown in Figure 2)
There are a plurality of suction ripple medium jacks (7) described support ring (6) cross section inside, inhales and inserts bar-shaped suction ripple medium in the ripple medium jack (7), and length is identical with furnace chamber inner housing length.
Said furnace chamber inner housing material is for passing through the ripple pottery.
Said suction ripple medium is a compound carbofrax material, and by carborundum, silicon nitride, boron nitride are composited.The effect of carborundum is to absorb microwave; Main effect is to improve absorbing property, and the silicon nitride that is obtained by the metallic silicon sintering reaction combines to form body portion with carborundum particle is powerful, has high strength, high rigidity and highly-acidproof; And be electrical insulator; In sintered body, disperse carborundum, increase the intensity of sintered body, prevent silicon nitride oxidation at high temperature; Under the rapid impact condition of High-Power Microwave, require microwave-absorbing body to have anti-sometimes hot and sometimes cold thermal shock property.Boron nitride has bigger thermal conductivity, low elastic modelling quantity and thermal shock resistance.And because the interpolation of boron nitride, the sintered body thermal shock resistance that the silicon nitride sintering reaction combines improves significantly.
The beneficial effect of the utility model is:
Inhaling the ripple medium is compound carbofrax material, and by carborundum, silicon nitride, boron nitride are composited.The effect of carborundum is to absorb microwave; Main effect is to improve absorbing property, and the silicon nitride that is obtained by the metallic silicon sintering reaction combines to form body portion with carborundum particle is powerful, has high strength, high rigidity and highly-acidproof; And be electrical insulator; In sintered body, disperse carborundum, increase the intensity of sintered body, prevent silicon nitride oxidation at high temperature; Under the rapid impact condition of High-Power Microwave, require microwave-absorbing body to have anti-sometimes hot and sometimes cold thermal shock property.Boron nitride has bigger thermal conductivity, low elastic modelling quantity and thermal shock resistance.And because the interpolation of boron nitride, the sintered body thermal shock resistance that the silicon nitride sintering reaction combines improves significantly.
It is inhomogeneous to have solved microwave tubular type furnace interior heating, and the problem that SR is bigger has reduced the error of microwave tube furnace thermometric, has also improved the structural behaviour of microwave tube furnace.
