Description

Technical Field

[0001] The utility model relates to the technical field of phosphorus oxychloride tail gas utilization equipment, in particular to a phosphorus oxychloride tail gas recycling utilization device. Background Art

[0002] Phosphorus oxychloride is an industrial chemical raw material, a colorless, transparent, fuming liquid, widely used in the production of pesticides, medicines, dyes, phosphates and flame retardants. It is a raw material for the manufacture of organophosphorus pesticides, herbicides, chlordimeform, etc. It is used in the production of plastic plasticizers. It is also used in the chlorination reaction of long-acting sulfonamide drugs. It is an intermediate in the production of dyes, a chlorinating agent and catalyst for organic synthesis, a uranium ore extractant, etc. The actual production of phosphorus oxychloride will be accompanied by tail gas. In order to avoid the pollution of the environment by the tail gas of phosphorus oxychloride, phosphorus oxychloride tail gas recycling devices are now mostly used to achieve the purpose of recycling the tail gas of phosphorus oxychloride.

[0003] The prior art discloses a phosphorus oxychloride tail gas recycling device with publication number: CN206103390U, which includes a reactor, a condenser, a delivery pump, a first inlet, a second inlet, a reactor outlet, a condenser inlet, a condensate outlet and a tail gas outlet. The phosphorus oxychloride tail gas generated in the upstream process enters the reactor through the first inlet, and then the excess tail gas is delivered to the condenser through the delivery pump. Part of the tail gas is condensed into condensate in the condenser, and re-enters the reactor through the second inlet along the condensate outlet for reaction. A small amount of phosphorus oxychloride tail gas enters the tail gas absorption tower through the tail gas outlet for treatment and then is discharged. Most of the phosphorus oxychloride tail gas is reabsorbed and utilized, and only a small amount of tail gas is discharged, which improves the output and waste utilization rate while greatly reducing environmental pollution, achieving small or even zero emissions.

[0036] Working principle:

[0037] When the phosphorus oxychloride tail gas recycling device is actually used, the operator first moves the four sets of mounting plates 18 by hand. When the four sets of mounting plates 18 are moved to a suitable position, the four sets of mounting screws 16 and the eight sets of mounting nuts 17 are used to cooperate with each other. The operator manually rotates the eight sets of mounting nuts 17 clockwise and counterclockwise. When the eight sets of mounting nuts 17 are in close contact with the four sets of socket plates 12, the use position of the four sets of mounting plates 18 is fixed. At this time, the two sets of connecting pipes 9 and the circulation pipe 11 can be placed inside the eight sets of U-shaped plates 30. At this time, the two sets of U-shaped plates 30 can be moved horizontally or rotated. The two sets of connecting pipes 9 and the circulating pipe 11 are connected to each other by bolts. When the two sets of connecting pipes 9 and the circulating pipe 11 are transversely moved or rotated to a suitable position, the two sets of connecting pipes 9 and the circulating pipe 11 can be connected to the inlet pipe 5, the outlet pipe 6, the condensate discharge pipe 7 and the inlet pipe 8 by using eight sets of U-shaped plates 30. At this time, due to the presence of eight sets of U-shaped plates 30, it is not necessary for the operator to lift the two sets of connecting pipes 9 and the circulating pipe 11 for a long time. The socket plate 12 is provided with an auxiliary structure, which can save effort and conveniently complete the connection of the pipelines, thereby improving the efficiency of the phosphorus oxychloride tail gas recycling device. At the same time, when there is leakage at the connection between the inlet pipe 5, the outlet pipe 6, the condensate discharge pipe 7 and the inlet pipe 8, the leaked liquid will fall into the inside of the groove plate 14 through the support filter 26 under the action of gravity. As the dripping liquid increases, the groove plate 14 will be pressed down, and the groove plate 14 will pull the three groups of telescopic hoses 29 and squeeze the two groups of telescopic springs 22. When the groove plate 14 presses the push switch 25, the buzzer alarm 24 starts to work, and the operator can hear the sound emitted by the buzzer alarm 24. To find out whether there is leakage, the operator removes the two sets of cover plates 27 and can remove the liquid inside the groove plate 14 through the through holes of the two sets of cover plates 27. The three sets of support columns 13 serve to guide the groove plate 14, and the three sets of fixed orifice plates 28 serve to install three sets of telescopic hoses 29. The groove plate 14 can remind the operator whether there is leakage at the connection between the inlet pipe 5, the outlet pipe 6, the condensate discharge pipe 7 and the inlet pipe 8, thereby ensuring the continuous use of the phosphorus oxychloride tail gas recycling device.

Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
