Further, be provided with two sieve plates in the tank body, upper sieve plate is arranged on the below of overflow pipe lower limb place horizontal plane, and following sieve plate is arranged on the below of upper sieve plate.
Further, the sieve aperture that is provided with on the upper sieve plate is slightly less than down the sieve aperture that is provided with on the sieve plate.
Further, the outer surface of tank body is provided with chuck, and chuck is provided with circulating water inlet and circulating water outlet pipe.
Further, the bottom of tank body is provided with the bottom valve interface.
The beneficial effects of the utility model are:
The utility model is realized the phosphorus trichloride removal of impurities with the conventional way of phosphorus trichloride solution washing phosphorus trichloride gas, but realize that the equipment of this way is different with existing device, phosphorus trichloride washing tank equipment described in the utility model is simple, easy to use, removal of impurities rapidly and efficiently, the phosphorus trichloride gas high purity that obtains.The utility model is provided with two-layer sieve plate in tank body, be upper sieve plate and following sieve plate, upper sieve plate is arranged on the below of overflow pipe lower limb place horizontal plane, following sieve plate is arranged on the below of upper sieve plate, be provided with centre bore and a plurality of sieve aperture on the sieve plate, the centre bore that air inlet pipe is passed sieve plate directly arrive sieve plate down below.The external reactor of overflow pipe, all phosphorus trichloride solution below the horizontal plane of overflow pipe place, phosphorus trichloride gas directly leads to down below the sieve plate by air inlet pipe, gas is in reflux course, filtration, cooling through phosphorus trichloride solution, portion gas can liquefy, the liquid phosphorus trichloride in the tank body by phosphorus trichloride gas is carried out condensation and in reactor overflow keep the stable of liquid level in the tank body, this has guaranteed that also the yellow phosphorus content in the liquid phosphorus trichloride is unlikely to too high simultaneously.The two-layer sieve plate that the utility model adopts plays buffering, distribution effect again to the backflow of phosphorus trichloride gas, make phosphorus trichloride gas with jar in the abundant mixing, washing of phosphorus trichloride solution, the free phosphorus of wherein carrying secretly is trapped in the liquid, thereby obtains pure phosphorus trichloride gas.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the enlarged diagram of following sieve plate among Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As shown in Figure 1 and Figure 2, phosphorus trichloride washing tank described in the utility model, mainly form by the air inlet pipe 2 that is provided with on tank body 1 and the tank body, escape pipe 3, overflow pipe 5, wherein, be provided with two sieve plates in the tank body 1, be upper sieve plate 9 and following sieve plate 8, upper sieve plate 9 is arranged on the below of overflow pipe 5 lower limb place horizontal planes, and following sieve plate 8 is arranged on the below of upper sieve plate 9.Sieve plate is provided with sieve aperture and centre bore, and the sieve aperture that is provided with on the upper sieve plate 9 is slightly less than play the sieve aperture 11 of setting on the sieve plate 8, and the centre bore 12 that air inlet pipe 2 is passed upper sieve plate 9 centre bores and following sieve plate 8 is fixedlyed connected with sieve plate.The outer surface of tank body 1 is provided with chuck 4, and chuck 4 is provided with circulating water inlet 6 and circulating water outlet pipe 10.The bottom of tank body also is provided with bottom valve interface 7.
The utility model is provided with upper sieve plate 9 and following sieve plate 8 in tank body 1, be provided with centre bore and a plurality of sieve aperture on the sieve plate, upper sieve plate 9 is arranged on the below of overflow pipe 5 lower limb place horizontal planes, following sieve plate 8 is arranged on the 40-60cm place, below of upper sieve plate 9, the centre bore 12 that air inlet pipe 2 is passed upper sieve plate 9 centre bores and following sieve plate 8 is fixedlyed connected with sieve plate, and directly lead to down sieve plate 8 below.Phosphorus trichloride gas by air inlet pipe 2 directly lead to down sieve plate 8 below.Because the phosphorus trichloride gas that comes out from reactor is high-temperature gas, injection along with gas, phosphorus trichloride solution and phosphorus trichloride gas carry out heat exchange, the temperature of phosphorus trichloride solution also can raise gradually, phosphorus trichloride in the solution can evaporate along with the rising of temperature, and what this part evaporated is pure phosphorus trichloride gas.Another outstanding advantage of the present utility model is to be provided with a plurality of sieve apertures on the upper sieve plate 9, is provided with a plurality of sieve apertures 11 on the following sieve plate 8, and the diameter of the sieve aperture on the upper sieve plate 9 is 2-4cm, and the diameter of the sieve aperture 11 on the following sieve plate 8 is 3-5cm.So like this, the backflow of upper sieve plate 9 and 8 pairs of phosphorus trichloride gases of following sieve plate plays fine buffering, distribution effect again, make the phosphorus trichloride solution in phosphorus trichloride gas and the tank body 1 fully mix, wash, the free phosphorus of wherein carrying secretly is trapped in the phosphorus trichloride solution, thereby obtains pure phosphorus trichloride gas.
In industrial processes, along with the phosphorus trichloride high-temperature gas that comes out from reactor constantly is passed in the tank body 1, the temperature of phosphorus trichloride solution can constantly raise in the tank body 1, it will reduce gradually to cooling, the filtration of phosphorus trichloride gas, and the degree of purity of the phosphorus trichloride gas that comes out from escape pipe 3 will be had a greatly reduced quality.The outer surface of tank body 1 described in the utility model is provided with chuck 4, and chuck 4 is provided with circulating water inlet 6 and circulating water outlet pipe 10.Feed cold water in the chuck 4 incessantly, can make the outer wall of cold water and tank body 1 carry out heat exchange, thereby reduce the temperature of the phosphorus trichloride solution in the tank body 1, guarantee that industrial production ground carries out smoothly.This cooling means is simple, easy-to-use, and is less demanding to appointed condition, saved industrial cost to a great extent.
Overflow pipe 5 external reactors described in the utility model, the phosphorus trichloride gas that enters tank body 1 can part cool off, liquefy in tank body 1, liquid phosphorus trichloride in the tank body 1 by phosphorus trichloride gas is carried out condensation and in reactor overflow keep the stable of liquid level in the tank body, this has guaranteed that also the yellow phosphorus content in the liquid phosphorus trichloride is unlikely to too high simultaneously.
The bottom of tank body 1 also is provided with bottom valve interface 7, by bottom valve interface 7 for can tank body 1 being cleaned.
In the industrial manufacture process of phosphorus trichloride gas, by installing the phosphorus trichloride washing tank additional, the throughput rate of phosphorus trichloride doubles, and free phosphorus content is lower than 0.0010% in the finished product phosphorus trichloride, reaches the high-class product standard.And this washing tank equipment is simple, easy to use, can effectively reduce manufacturing cost, saves social resources.
Be noted that at last the above embodiment be explanation to technical solutions of the utility model and unrestricted, described phosphorus trichloride washing tank is not a phosphorus trichloride gas specific washing tank, is well-adapted for other gas yet; The quantity of described sieve plate, the size of sieve aperture and quantity all can increase or reduce according to the actual needs on distance between the sieve plate and the sieve plate, other modification that is equal to replacement or makes of affiliated technical field those of ordinary skill according to prior art, as long as do not exceed the thinking and the scope of technical solutions of the utility model, all should be included within the desired interest field of the utility model.
