Description
Technical field
This utility model relates to phosphorous chemical industry production field, and be particularly used on Phosphorous chloride. production line washes phosphorus tower.
Background technology
At present, Phosphorous chloride. all uses conventional filler tower, packed tower top uses a liquid distribution trough, backflow is distributed on filler through distributor, liquid is through filler toward dirty, and gas is up evaporated by the bottom of tower, makes gas-liquid two-phase inversely connect in packing layer and melts, separate different with boiling point height for solid granule in gas, reach to wash phosphorus effect.And the free phosphorus of chlorination reaction can not get fully connecing and melts washes clean, finely ground particles and free phosphorus also easily enter into next link together along with finished product, reduce end product quality.
Utility model content
The purpose of this utility model is aiming at present, Phosphorous chloride. all uses conventional filler tower, packed tower top uses a liquid distribution trough, backflow is distributed on filler through distributor, liquid is through filler toward dirty, and gas is up evaporated by the bottom of tower, makes gas-liquid two-phase inversely connect in packing layer and melts, separate different with boiling point height for solid granule in gas, reach to wash phosphorus effect.And the free phosphorus of chlorination reaction can not get fully connecing and melts washes clean, finely ground particles and free phosphorus also easily enter into next link together along with finished product, reduce the deficiency of end product quality, and provide and wash phosphorus tower on Phosphorous chloride. production line.

Detailed description of the invention
nullAs shown in Figure 1，This utility model includes tower body 1、At the bottom of tower 2、First filler chamber 3、Second filler chamber 4、Distributor 5、A pair grid 6、Drain valve 7、Compression pump 8、Intake valve 9、One group of shower nozzle 11 and air bleeding valve 12，Described tower body 1 is divided into upper and lower two joints，And connected by flange 10，Upper tower body top side has inlet and gas outlet，And inlet is positioned at below gas outlet，Lower tower body bottom side has air inlet，Outage is had bottom 2 at the bottom of tower，At the bottom of tower, 2 are arranged on bottom lower tower body，And communicate with lower tower body，Drain valve 7 is arranged at the bottom of tower on the outage bottom 2，A pair grid 6 is separately mounted in upper and lower two joint tower bodies，And the aperture of a pair grid 6 is 15-25mm,First filler chamber 3 and the second filler chamber 4 are separately mounted in upper and lower two joint tower bodies，And lay respectively at above a pair grid 6，Distributor 5 is arranged in tower body，And be positioned at below grid 6，Air bleeding valve 12 and intake valve 9 are separately mounted on tower body and the gas outlet of lower tower body and air inlet，One group of shower nozzle 11 is arranged in tower body，And be positioned at above the second filler chamber 4，At the bottom of tower, the outage of 2 is communicated by the inlet of compression pump 8 with one group of shower nozzle 11.
It also has level indicator and adjustable support 13, level indicator and adjustable support 13 to be separately mounted to bottom tower body 1.
It also has liquidometer and PLC, and in liquidometer is arranged at the bottom of tower 2, and liquidometer is electrically connected with PLC by input module, the opening and closing of PLC control compression pump 8.
nullOperation principle: during work, liquid is sprayed in the second filler chamber 4 by one group of shower nozzle 11，Gas enters into lower tower body by intake valve 9，Flowed up by pressed gas，Liquid passes through the second filler chamber 4、Grid 6、Distributor 5 and the first filler chamber 3 flow downward，While flowing, gas contacts with liquid and reacts，Gas is continuing up after the reaction of the first filler chamber 3，By distributor 5 and grid 6 respectively uniformly after enter into the second filler chamber 4 in carry out double purification，Purified gas is discharged by air bleeding valve 12，Enter into next link，Participate in reacted liquid drops at the bottom of tower 2，It is transported in feed tube by the liquid at the bottom of 8 towers of compression pump 2 again，Sprayed in the second filler chamber 4 by one group of shower nozzle 11 together with the liquid in pipeline，Carry out again with，When at the bottom of tower, the liquid level in 2 is too low，Liquidometer data transmission to PLC，PLC controls compression pump 8 and reduces transporting velocity or closing presure pump 8，Avoid liquid level too low，Gas in lower tower body is delivered directly in upper tower body，By the time liquid level is normally then turned on，Play and be automatically adjusted at the bottom of tower the effect of liquid level in 2.Level indicator and adjustable support 13 can conveniently regulate the levelness of tower body 1, it is to avoid after tower body 1 tilts, gas-to-liquid contact is uneven and reduce reaction mass.
