Description

Technical Field

[0001] This utility model relates to the technical field of phosphorus trichloride recovery equipment, and in particular to a phosphorus trichloride gaseous cooling and recovery device. Background Technology

[0002] Phosphorus trichloride is a colorless, transparent liquid that is soluble in benzene, ether, carbon disulfide, and carbon tetrachloride. It undergoes hydrolysis in water and produces hydrochloric acid mist in air, which is irritating and corrosive to skin and mucous membranes. In its production, dry chlorine gas is passed into a mixed solution of phosphorus and phosphorus trichloride, resulting in an exothermic reaction that produces gaseous phosphorus trichloride. This gaseous phosphorus trichloride is then cooled to obtain phosphorus trichloride.

[0003] According to Chinese Patent No. CN215177116U, a phosphorus trichloride gaseous cooling and recovery device is provided. The phosphorus trichloride cooling device includes a cooling tank and a heat exchange tube. A phosphorus trichloride inlet is provided on one side of the upper part of the cooling tank, and the phosphorus trichloride entering at the inlet is in a high-temperature mist state. A phosphorus trichloride outlet is provided on one side of the lower part of the cooling tank, and the phosphorus trichloride exiting at the outlet is in a liquid state. A heat exchange tube is installed inside the cooling tank, and both penetration points of the heat exchange tube into the cooling tank are sealed. One end of the heat exchange tube is connected to a coolant inlet chamber, and a coolant recovery chamber is provided on one side of the coolant outlet at the other end of the heat exchange tube. There is a heat exchange tube damage observation area between the coolant recovery chamber and the coolant outlet. Workers can observe the heat exchange tube damage in the observation area. If white smoke is found coming out of the cooling water, it indicates that the heat exchange tube is broken, which can be easily detected.

[0004] The aforementioned patent has a good effect of facilitating observation, but most of the water flows directly away from the middle of the heat exchange tube, which will result in a slow cooling rate of phosphorus trichloride and reduce the cooling recovery efficiency of phosphorus trichloride.

[0018] A further feature of this invention is that one end of the discharge pipe is located inside the water tank, and a valve is fixedly connected to one end of the discharge pipe.

[0019] By adopting the above technical solution, the discharge pipe can be kept in a relatively stable environment, improving the cooling and recovery effect, while the valve can control the discharge.

[0020] A further feature of this invention is that the spraying mechanism includes a water pump, one end of which is fixedly connected to a spray pipe, and one end of which is fixedly connected to a spray head.

[0021] By adopting the above technical solution, the spray mechanism can improve evaporation and thus improve cooling efficiency.

[0022] A further feature of this invention is that a fan unit is fixedly connected to the inner wall of the wind power port, and a dustproof mesh is fixedly connected to the front of the wind power port.

[0023] By adopting the above technical solutions, the fan unit can accelerate air circulation, thereby accelerating evaporation and improving the cooling effect. The dustproof screen can isolate dust in the air and improve the utilization rate of cooling water in the water tank.

[0024] A further feature of this invention is that the number of dustproof meshes is two, with the other dustproof mesh being disposed on the back of the main body.

[0025] By adopting the above technical solution, the dustproof mesh improves the permeability of the device, isolates the internal and external environments while promoting air circulation to ensure the cooling effect.
