A chemical proportioning device for vinyl chloride isobaric temperature swing adsorption dehydration process

Abstract

The invention belongs to the field of chemical industry, and proposes a chemical proportioning device for a vinyl chloride isobaric temperature swing adsorption dehydration process, including a proportioning box; a columnar cavity is arranged in the proportioning box, and a horizontally disposed inside the proportioning box The first partition, and the first partition divides the columnar cavity into a first cavity and a second cavity, and the first cavity is located above the second cavity; There is a fixed pipe, and the upper and lower ends of the fixed pipe are respectively fixedly connected with the top center of the inner wall of the proportioning box and the center of the upper surface of the first partition; the center of the first partition is provided with a second through hole, and the fixed The inner diameter of the tube is equal to the diameter of the second through hole, and the central axis of the two coincides; the present invention sets an adjustment component in the cabin that can adjust the volume of the cavity, and does not need the staff to repeatedly measure the dosage of the medicine when the medicine is mixed. , which improves the work efficiency, and the staff will not come into contact with the medicament during the proportioning process, making it safer to use.

Description

Technical field [0001] The present invention belongs to the chemical field, particularly relates to a kind of vinyl chloride isobaric temperature absorption dehydration process for pharmaceutical ratio device. Background [0002] Isobaric thermostatic adsorption dehydration is a very effective dehydration process to reduce the moisture in vinyl chloride monomer, and the continuity of isobaric subthermal adsorption dehydration process production is high and relatively stable, and the use cycle of the agent used in the process is more than 5 years, so the raw material requirements required for pharmaceutical production are more stringent. [0003] For example, patent no. CN201920342143.9 of an SNCR denitrant automatic production line with a pharmaceutical compounding reaction device, which includes a mixing barrel, a stirring device disposed in the mixing barrel and a spiral elevator disposed above the mixing barrel; the device transports the agent to the mixing barrel by a spiral ...

Problems solved by technology

[0003] Such as patent number CN201920342143.9, a medicament proportioning reaction device for an SNCR denitration agent automatic production line, which includes a mixing tank, a stirring device arranged in the mixing tank and a screw elevator arranged above the mixing tank; the device is lifted by a screw The medicine is delivered to the mixing tank by the machine, and the dosage and speed of the medicine are controlled by controlling the speed of the screw elevator, so as to mix evenly when stirring in the mixing tank; but when the screw elevator is used to transport the medicine, the medicine is affected by the running speed of the screw elevator. The impact is easy to spray, and the agent splashed on the outside of the mixing tank may cause corrosion on the bottom surface, and the screw elevator is large in size and high in equipment cost, so it is not suitable for the ratio of agents with high precision
