Abstract

The invention discloses gas drying equipment for phosphorus oxychloride production. The gas drying equipment comprises a front cover and a drying cylinder, the front cover is mounted on the outer wallof the front end of the drying cylinder; an inlet pipe is arranged on the circumferential outer wall of the upper end of the front side of the drying cylinder; gas produced by phosphorus oxychlorideabsorbs moisture produced by chemical reaction after high temperature through the activated carbon adsorption layer, the goal of drying is further achieved; at the moment, gas produced by phosphorus oxychloride is introduced into the display layer, and the display layer is made of allochroic silica gel filler; when the allochroic silica gel filler adsorbs water, the color is blue and thus the operator is timely reminded that moisture adsorption is saturated and the moisture in the gas produced by phosphorus oxychloride is not completely adsorbed and dried and the gas needs to be dried again. The gas drying equipment for phosphorus oxychloride production has the advantages that the structure is simple, the gas distribution is more uniform, the gas-solid contact is more sufficient, and the moisture adsorption efficiency is greatly improved due to the multiple layers of separation nets in the drying cylinder.

Description

technical field [0001] The invention belongs to the related technical field of gas drying equipment, and in particular relates to a gas drying equipment used for the production of phosphorus oxychloride. Background technique [0002] Air drying is the removal of moisture in the air, and there are two major forms: adsorption and refrigeration. The adsorption compressed air dryer uses the principle of pressure swing adsorption. When the wet air passes through the adsorbent, the moisture is absorbed to obtain dry air; the refrigerated compressed air dryer uses the principle of cooling the air and reducing the air temperature to remove Moisture is precipitated from the air after condensation to obtain dry air. The heatless regenerative air dryer achieves the drying effect through "pressure change" (principle of pressure swing adsorption). Since the ability of the gas to hold water vapor is inversely proportional to the pressure, a part of the dried gas (called the regeneration ...
