Abstract
The utility model relates to a device which is used for preparing phosphorus pentachloride, belonging to a synthesizing tower with double layer structural type which is made of anticorrosive enamel materials and steel plates. The synthesizing tower completes the preparing process of phosphorus pentachloride once through a raw material input pipe and a product material outlet device. The produced products has high content and good quality. The utility model does not pollute environment in the process of preparation, being capable of carrying out industrialized production.
Description
A kind of device for preparing phosphorus pentachloride belongs to Chemical Manufacture neck city.
Phosphorus pentachloride is a kind of Chemicals, be applied as chlorizating agent, catalyzer, domestic existing limited production, and the major equipment of producing it is reactor and centrifugal drier, after being about to phosphorus trichloride and placing reactor, adds chlorine and chemical reaction takes place, then reaction product is separated by centrifugal drier, obtain the intact phosphorus trichloride of phosphorus pentachloride and unreacted.Utilize this product of this device fabrication, have two big disadvantages, the one, institute's product content that obtains is low, and promptly qualification rate is low; The 2nd, phosphorus pentachloride and phosphorus trichloride have certain toxicity, contact with damp atmosphere to take place to decompose to generate hydrogen chloride gas, thereby utilize centrifugal drier to separate very easily to produce and decompose and contaminate environment, even bring harm to people and animals.
The purpose of this utility model is the product of producing at aforesaid device, and content is low, and the disadvantage of contaminate environment designs a kind of can improving the quality of products, preparation facilities free from environmental pollution.
The utility model is realized in the following manner, add steel plate with enamel material and make double-deck synthetic tower, be hollow entirely in the tower, it at the bottom of the tower taper, a screw propulsion discharger is adorned at its end, draws pack into the bottom of synthetic tower of a pipe from the chlorine basin, draws pack into the top of synthetic tower of a pipe from the phosphorus trichloride basin, utilize the pressure effect, with the vaporific synthetic tower top that sprays into of phosphorus trichloride.The chlorine that rises and the phosphorus trichloride of vaporific decline react, and reaction formula is; PCI
3+ CI
2=PCI
5, generate the phosphorus pentachloride xln and fall bottom the synthetic tower, come out by the rotation of screw propulsion discharger again, enter in the packaging vessel.
The present invention has following advantage and effect, and reactant reaction is complete, the quality product height, and also free from environmental pollution, but suitability for industrialized production.
Accompanying drawing drawing explanation: Fig. 1 synthetic tower front view, Fig. 2 nozzle sectional view, Fig. 3 nozzle mouth front view, Fig. 4 screw propulsion discharger front view, Fig. 1 accompanying drawing that also makes an abstract.
Describe details of the present utility model in detail below in conjunction with the embodiment accompanying drawing:
The double-deck synthetic tower that the utility model adopts enamel material and steel plate to make, see accompanying drawing 1, internal layer is the thick enamel material (1) of the erosion-resisting 1-2cm of energy, outer with steel plate (2) reinforcing, adorning a phosphorus trichloride feed-pipe (3) the certain position of distance cat head (also can at cat head) feeds in the tower, synthetic tower is communicated with the phosphorus trichloride basin, the end of feed-pipe (3) is equipped with nozzle (4) in the tower, feed-pipe (3) is if when being contained in apart from the certain position of cat head, the mouth of nozzle (4) (best by this way) up enters the mouth down of nozzle (4) as if feed-pipe (3) from cat head.Adorn a chlorine input tube (5) in the tower body bottom and go in the tower, tower bottom is tapered, adorns a screw propulsion discharger (6) at the bottom of the tower, and the available manual operation of screw propulsion discharger (6) is rotated, and also available power drives.
During production the ratio of the phosphorus trichloride of a moL and a moL chlorine is respectively charged in the basin separately, the phosphorus trichloride basin places and is higher than the certain position of synthetic tower, utilize the pressure of its height self, also can in basin, add rare gas element pressurizations such as nitrogen, make phosphorus trichloride pass through feed-pipe nozzle (4) and form vaporific spraying in the tower.Operation steps is as follows: the first step is opened chlorine basin valve, allow chlorine enter the bottom of tower one step ahead toward rising, second step was opened phosphorus trichloride basin valve, phosphorus trichloride forms through nozzle (4) under the effect of pressure and vaporificly sprays into top of tower and slowly descend, when phosphorus trichloride contact with chlorine chemical reaction, generation phosphorus pentachloride just take place is crystalloid and falls tower at the bottom of.The 3rd step was produced the regular hour just the valve closes of two material storaging tanks, rotated screw propulsion discharger (6) at last, and phosphorus pentachloride promptly goes out along screw propulsion discharger (6), enters in the packaging vessel.
Application Example:, made 80 centimetres of middle part internal diameters, high 700 centimetres synthetic tower according to the structure of above-mentioned synthetic tower, used aborning, this synthetic tower can be produced 1.5 tons phosphorus pentachloride in per 24 hours, and product appearance is white in color or faint yellow granular crystal body, content 〉=96%.
Claims (2)
1, the bilayer structure formula synthetic tower made by steel plate, enamel material of a kind of device for preparing phosphorus pentachloride is characterized in that the phosphorus trichloride feed-pipe is equipped with on the top of synthetic tower, and the chlorine input tube is equipped with in the tower bottom, is provided with discharger at the bottom of the tower.
2, device according to claim 1 is characterized in that the phosphorus trichloride feed-pipe is equipped with nozzle.
