The utility model content
The purpose of this utility model is to provide a kind of isolated plant of atomizing and oxidizing solution.To be implemented in uniformity of temperature profile in the oxidation reaction, reaction is efficient, quick, shortened process significantly, can realize automation, serialization production, and the gas that produces in the recyclable course of reaction, no waste produces, and environmentally safe can realize that resource circulation utilization and easy operating, raw material are applied widely.
The technical solution of the utility model is:, be provided with a vertical tubular electric furnace that has 2-6 group electric heating system, in the reaction tube of vertical tubular electric furnace inside, be provided with disturbing flow device, be provided with seal cover at the reaction tube top, seal cover is provided with the solution atomization device, and the discharging opening of vertical tubular electric furnace bottom is connected with cyclone separator.
Described reaction tube diameter is 50-500mm.
The gas phase of described cyclone separator is connected with the gas absorbing device that reclaims gas.
Described cyclone separator is 2, is to adopt the cyclone separator that has the continuous pulp discharge device in the prior art.
The electric heating system of described vertical tubular electric furnace is four groups.
Described solution atomization device is a pneumatic atomizer.Can realize high-efficient atomizing; Can effectively control reacting dose by regulating atomizer.
Described disturbing flow device is to be provided with the spiral catch that extends vertically in reaction tube.
Described gas absorbing device is the water wash absorption tower of 2 polyphones.
The utility model becomes the little droplet of superfine liquid by the solution atomization device with the material solution atomizing, makes it have higher specific surface area, and the little droplet of the liquid after the atomizing fully mixes rear oxidation with air in the vertical tubular electric furnace of high temperature be oxide powder.Oxide powder is by the two-stage efficient cyclone separator, utilizes the centrifugal force that produces when containing the fine powder air-flow and rotating, and fine powder is separated from gas.Powder is collected the back by the continuous pulp discharge device on the cyclone separator and is discharged.Collection rate can reach more than 90%, and the soluble gas in the gas phase is recycled by the drip washing absorption tower, to be used to make various diluted acids (watery hydrochloric acid, dilute sulfuric acid, rare nitric acid).Exquisite, tiny, the uniformity of temperature profile of whole device, reaction is efficient, fast, shortened process significantly, easy operating; This equipment capacity is big, is fit to serialization production; Raw material is applied widely, and the whole system no waste produces, environmentally safe, and can realize that resource circulation utilizes again.
Description of drawings
Accompanying drawing is the structural representation of the utility model one embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described further.
Embodiment:
Present embodiment is provided with a vertical tubular electric furnace 1 that has four groups of electric heating systems, and the reaction tube 2 in the inside of vertical tubular electric furnace is at reaction tube 2 outside fill insulant materials 6.In reaction tube 2, be provided with disturbing flow device, present embodiment is a spiral catch 7 that extends vertically, be provided with seal cover 3 at the reaction tube top, seal cover is provided with pneumatic atomizer 4, pneumatic atomizer with held material solution container 9 and be communicated with, by the size of flowmeter 8 control flows, compressed air is by air compressor 10 inputs.
It is the solution after the atomizing to be heated to by room temperature react temperature required that first group of heating system 11-1 mainly acts on, second and third group heating system 11-2,11-3 keep the needed temperature of reaction, and the 4th group of heating system 11-4 is that the assurance oxidation reaction can not carried out to the back reaction direction in the exit.Thermocouple probe by heating control system guarantee temperature accuracy be controlled at ± 2 ℃
The discharging opening 5 of vertical tubular electric furnace bottom is connected with 12-2 with two stage cyclone separator 12-1, utilizes the centrifugal force that produces when containing the fine powder air-flow and rotating, and fine powder is separated from gas.Powder is collected and is discharged by the continuous pulp discharge device on the cyclone separator 13.Collection rate can reach more than 90%.The air-flow of having collected powdered product feeds drip washing absorption tower 14-1 through pipeline, water flows into through recirculated water inlet 19 and carries out drip washing, gas obtains sufficient cooling therein, soluble constituent in the gas is dissolved in the condensed water, restored acid flows in the acid tank 21 by pipeline, and remaining gas phase fully absorbs through absorption tower, second level 14-2 again.The waste gas that meets environmental protection standard at last through pipeline by exhaust fan 20 emptyings that have frequency conversion function,
Outside gas, rush down and produce pollution air, air pressure in reaction tube and the gas recovery system is slightly negative, and this can realize by the air circulation of regulating exhaust fan, and the adjusting by air quantity, can increase solution after the atomizing in the time of staying of reaction tube, be to react more abundant.
