Abstract

The invention relates to a phosphorus wash tower of phosphorous trichloride. The phosphorus wash tower comprises a tower bottom (2), a tower body (7), an initial distributor (13) and a tower top (14), which are connected into an integral body. The phosphorus wash tower is characterized in that: the lower part of the tower body (7) is provided with a lower filling chamber (6), both ends of the lower filling chamber (6) are provided with a grid holder (8) and a lower fence (5), the upper part of the tower body (7) is provided with an upper filling chamber (11), and the lower part of the upper filling chamber (11) is provided with an upper fence (10); and a redistributor (9) is arranged between the grid holder (8) and the upper fence (10). The phosphorus wash tower of phosphorous trichlorideof the present invention which allows a further full contact between the gas phase and the liquid phase to be realized overcomes an abuse that minimal particles and free phosphorus can easily enter aliquid finished product of phosphorus trichloride along the wall of the phosphorus wash tower or are condensed by a condenser because of being entrained by gases.

Description

technical field [0001] The invention belongs to environmental protection equipment, in particular to a phosphorus trichloride phosphorus washing tower capable of fully exchanging gas and liquid phases. Background technique [0002] Phosphorus washing tower is one of the main equipments for producing phosphorus trichloride. The structure of the tower is different, the interface between gas and liquid is also different, and the effect is also different. At present, most domestic enterprises use traditional packed towers to produce phosphorus trichloride. A liquid distributor is used in the upper part of the packed tower. The reflux liquid is distributed to the packing through the distributor. The gas-liquid two-phase is reversely fused in the packing layer, and the small solid particles in the gas and the difference in boiling point are separated. To achieve the effect of phosphorus washing, but because the traditional packed tower only relies on the packing layer for gas-liq...
