Abstract
The invention relates to a novel isophthalonitrile carburetor. The carburetor comprises a vapor-phase inlet, a liquid-phase inlet, an atomizing nozzle, an inner tube, a heat-insulating ball valve and an inverse vapor-phase inlet, wherein the vapor-phase inlet is formed on the upper part of the carburetor; the liquid-phase inlet is formed at the outer end of the vapor-phase inlet; the atomizing nozzle is arranged in the carburetor and connected with the vapor-phase inlet; the inner tube is arranged in a cylinder on the middle part of the carburetor; the heat-insulating ball valve is arranged at the bottom of the carburetor; and the inverse vapor-phase inlet is formed on one side of the bottom of the carburetor. Compared with the prior art, the carburetor is simple in operation, so that 510 to 525kg of intermediate phthalonitrile is consumed to produce one ton of chlorothalonil, the life cycle of a catalyst is prolonged by 2 to 4 days, and the consumption of catalyst is reduced by 4 to 55kg during the production of one ton of phthalonitrile.
Description
Technical field
The present invention relates to a kind of vaporizer, especially relate 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
Purpose of the present invention 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.
Purpose of the present invention 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.
Described atomizer is vaporized in vaporizer after making the atomizing of liquid phase isophthalodinitrile.
Pipe has increased heat exchange area in described.
Described Thermal insulating ball valve regular cinder-discharge reduces objectionable impurities.
Compared with prior art, the present invention 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
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
