Abstract
The utility model relates to a salt adding device of a dehydrating tower kettle, which belongs to the technical field of chemical equipment. The salt adding device of the dehydrating tower kettle is characterized by comprising a conveying belt, a preparing tank is arranged below the discharging end of the conveying belt; a stirring rod is arranged inside the preparing tank; the bottom of the preparing tank is connected with the dehydrating tower kettle through a pipeline; and a valve is arranged on the pipeline. In the salt adding device of the dehydrating tower kettle, refined salt is conveyed into the preparing tank by the conveying belt and prepared into a NaCl solution; and after uniform stirring, the NaCl solution enters the dehydrating tower kettle through the pipeline and the concentration of chloride ions in tower kettle liquid is increased, so that the DCP decomposition is inhibited, the yield of HCl in the tower kettle liquid is reduced, the corrosion to equipment and the pipeline is reduced, the recycling capability of the dehydrating tower is improved, the yield is improved, the production cost is reduced, and the production control is stabilized.
Description
Technical field
The utility model relates to a kind of dehydrating tower still with the salt device, belongs to technical field of chemical.
Background technology
At present; Along with PO (expoxy propane) device is produced improving constantly of load, rectifying and dewatering production ability is obviously not enough, and particularly thick PO purity is low; Seriously restricted the load of rectifying column; Through the design temperature of dehydrating tower still temperature is improved, because of thick PO purity decline, the PO that rectifying column is discharged in the high liquid of mixing boiling point in the dehydrating tower still is able to abundant recovery.But existing dehydrating tower still exists because the raising of temperature accelerates DCP (Dicalcium Phosphate) decomposition rate in the dehydrating tower still, to seriously corrodeds such as tower still reboiler (titanium material), pipeline, valves in running.
The utility model content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: a kind of above-mentioned defective that solved is provided, has suppressed that DCP decomposes in the dehydrating tower still, alleviated dehydrating tower still to the corrosion of equipment and pipeline with the salt device.
The utility model solves the technical scheme that its technical problem adopted: described dehydrating tower still is with the salt device; It is characterized in that: comprise conveyer belt; The discharge end below of conveyer belt is provided with preparing tank; Be provided with stirring rod in the preparing tank, the bottom of preparing tank is connected with the dehydrating tower still through pipeline, and pipeline is provided with valve.
Also be provided with measuring pump on the pipeline between described preparing tank and the dehydrating tower still.Can carry out flow-control, thereby improve reaction effect.
During use, through conveyer belt refined salt is delivered in the preparing tank, is mixed with NaCl solution, after fully stirring, open valve, NaCl solution has increased the Cl in the tower bottoms in pipeline gets into the dehydrating tower still
-Concentration, thus the DCP decomposition suppressed, reduced the HCl growing amount in the tower bottoms, alleviated corrosion to equipment and pipeline.
The beneficial effect that the utility model had is: the dehydrating tower still is delivered to refined salt in the preparing tank through conveyer belt with the salt device, is mixed with NaCl solution, after fully stirring, opens valve, and NaCl solution has increased the Cl in the tower bottoms in pipeline gets into the dehydrating tower still
-Concentration, thus the DCP decomposition suppressed, having reduced the HCl growing amount in the tower bottoms, the corrosion that has alleviated equipment and pipeline alleviates, and has improved the recovery ability of dehydrating tower, has improved output, has reduced production cost, has stablized production control.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, conveyer belt; 2, preparing tank; 3, stirring rod; 4, dehydrating tower still; 5, valve; 6, measuring pump.
The specific embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, the discharge end below of conveyer belt 1 is provided with preparing tank 2, is provided with stirring rod 3 in the preparing tank 2, and the bottom of preparing tank 2 is connected with dehydrating tower still 4 through pipeline, and the pipeline between preparing tank 2 and the dehydrating tower still 4 is provided with valve 5 and measuring pump 6.
During use, refined salt is delivered in the preparing tank 2, is mixed with concentration and is 5～8% NaCl solution through conveyer belt 1; After stirring rod 3 fully stirs, open valve 5, through measuring pump 6 control flows; NaCl solution has increased the Cl in the tower bottoms in pipeline gets into dehydrating tower still 4
-Concentration, thus the DCP decomposition suppressed, reduced the HCl growing amount in the tower bottoms, alleviated corrosion to equipment and pipeline.
