Abstract
The utility model relates to a novel isophthalonitrile carburetor, which comprises a gas-phase inlet, a liquid-phase inlet, an atomizing spraying nozzle, an inner pipe, a heat insulation ball valve and an inverse gas-phase inlet, wherein the gas-phase inlet is arranged on the upper part of the carburetor, the liquid-phase inlet is arranged at the outer end of the gas-phase inlet, the atomizing spraying nozzle is arranged inside the carburetor and is connected with the gas-phase inlet, the inner pipe is arranged in the tube body of the middle part of the carburetor, the heat insulation ball valve is arranged on the bottom of the carburetor, and the inverse gas-phase inlet is arranged at one side of the bottom of the carburetor. Compared with the prior art, the utility model has the advantages that the operation is simple, the consumption of isophthalonitrile in the chlorothalonil production reaches 510 to 525 kg/t chlorothalonil, the use period of catalysts is prolonged by 2 to 4 days, and the consumption of the catalysts is reduced by 4 to 55 kg/t chlorothalonil.
Description
Technical field
The utility model relates to a kind of vaporizer, especially relates to a kind of novel isophthalodinitrile vaporizer.
Background technology
Termil is to be got through superchlorination in fluid bed by isophthalodinitrile.Termil, English chlorothalonil by name, the common name Bravo is a kind of wide-spectrum bactericide of high-efficiency low-toxicity, it mainly acts on is that the prevention crops are subjected to infecting of fungi, also is used as the protective agent of industrial fungicide, fruit antistaling agent, bactericide, coating and adhesive simultaneously.Domestic isophthalodinitrile (IPN) vaporization be adopt add telescopic, IPN liquefaction back sprays into from top, nitrogen up blows from the bottom, cylindrical shell external application conduction oil heats in adding cover, because nitrogen flow rate is fast, and spray into IPN is liquid, can only atomize and can not vaporize, at the bottom of making the big drop of IPN fall into vaporizer, and form polymerization IPN slag, be deposited on the vaporization agent bottom, and very droplet enters blender along with nitrogen, enters fluid bed and reacts, and a part of IPN droplet is stuck with paste the little micropore of dead catalyst, reduce catalyst service time, another part is just participated in reaction.
The IPN vaporizer that Bravo adopted that domestic chlorination production is come out mostly adopts to add telescopic vaporizer, and vaporization effect is not good, go out vaporizer and also contain a large amount of IPN droplets, and form vaporificly, and and make the IPN droplet stick with paste dead catalyst micropore, reduce the catalyst life cycle.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of simple to operate for the defective that overcomes above-mentioned prior art existence, reduces the novel isophthalodinitrile vaporizer of catalyst consumption.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel isophthalodinitrile vaporizer, it is characterized in that, this vaporizer comprises gas phase inlet, liquid phase inlet, atomizer, interior pipe, Thermal insulating ball valve and anti-gas phase inlet, described gas phase inlet is located at the top of vaporizer, described liquid phase inlet is located at the outer end of gas phase inlet, described atomizer is located at vaporizer inside, and be connected with gas phase inlet, pipe is located in the cylindrical shell at vaporizer middle part in described, described Thermal insulating ball valve is located at the bottom of vaporizer, and described anti-gas phase inlet is located at a side of vaporizer bottom.
Described gas phase inlet and anti-gas phase inlet are overheated nitrogen inlet.
Described liquid phase inlet is the isophthalodinitrile inlet.
Compared with prior art, the utility model is simple to operate, makes the consumption of isophthalodinitrile in the Bravo production reach the 510-525kg/t Bravo, and the catalyst life cycle increases 2-4 days, and the catalyst consumption amount reduces the 4-55kg/t Bravo.
Description of drawings
Fig. 1 is the structural representation of this vaporizer.
Among the figure 1 for gas phase inlet, 2 for liquid phase inlet, 3 be atomizer, 4 for interior pipe, 5 for Thermal insulating ball valve, 6 be that anti-gas phase enters the mouth.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of novel isophthalodinitrile vaporizer, this vaporizer comprises gas phase inlet 1, liquid phase inlet 2, atomizer 3, interior pipe 4, Thermal insulating ball valve 5 and anti-gas phase inlet 6, gas phase inlet 1 is located at the top of vaporizer, liquid phase inlet 2 is located at the outer end of gas phase inlet 1, be connected with the overheated nitrogen of part in the gas phase inlet 1, liquid phase inlet 2 is connected with the liquid phase isophthalodinitrile, atomizer 3 is located at vaporizer inside, and be connected with gas phase inlet 1, the liquid phase isophthalodinitrile under the nitrogen effect by nozzle atomization, in vaporizer, vaporize then, interior pipe 4 is located in the cylindrical shell at vaporizer middle part, has strengthened heat exchange area, and anti-gas phase inlet 6 is located at a side of vaporizer bottom, its inner hot nitrogen that feeds, mixed with the isophthalodinitrile formation adverse current under the spray of top, isophthalodinitrile is vaporized rapidly, reduce big drop and form, Thermal insulating ball valve 5 is located at the bottom of vaporizer, can regular cinder-discharge to reduce of the influence of other objectionable impurities to reaction.
Claims (3)
