Novel degasser

Abstract

The invention relates to a novel degasser which comprises a body; the body is a vacuum device; a material inlet is disposed at one side of the body; a material outlet for degassed materials is disposed at the lower end of the body; a gas inlet is disposed at the other side of the upper end of the body; a gas outlet is disposed at the same side as the material inlet on the body; a throwing disc made of hydrochloric acid corrosion-resistant materials is disposed in the body; the throwing disc is driven to rotate by a driving device at the upper end of the body; round holes or holes with other shapes and with a diameter of 2-10 mm are disposed on the side wall of the throwing disc; the rotating speed of the throwing disc is 30-200 r / min; a jacket is disposed at the outer side of the body; a heat source inlet with steam or heat-conductive oil as a heat source is disposed at one side of the jacket; and a heat source outlet is disposed at the other side of the jacket. The degasser of the invention is novel in structure, simple and convenient for operation, suitable for degassing of high-viscosity materials, strong in heat conduction function, and strong in corrosion resistance.

Description

Technical field [0001] The invention relates to a degassing device, in particular to a new type of degassing device with a spinner. Background technique [0002] Chlorinated paraffins are chlorinated derivatives of paraffin hydrocarbons. They have the advantages of low volatility, flame retardancy, good electrical insulation, and low price. They can be used as flame retardants and PVC plasticizers. They are now chlorinated at home and abroad. Paraffin wax is produced by continuous or batch method. The generated hydrogen chloride gas and unreacted chlorine gas are dissolved in chlorinated paraffin, and then it needs to go through a degassing process. There are three types of degassing devices. One is a common stirred reaction device. Such a device has a slow degassing speed, unstable product quality, and low production capacity. The other is a tubular falling film degassing tower. Although the production capacity is large, the degassing tower is not suitable for high-viscosity...

Problems solved by technology

[0002] Chlorinated paraffin is a chlorinated derivative of paraffin, which has the advantages of low volatility, flame retardancy, good electrical insulation, and low price. It can be used as a flame retardant and a PVC auxiliary plasticizer. Paraffin wax is produced continuously or intermittently. The produced hydrogen chloride gas and unreacted chlorine gas are dissolved in chlorinated paraffin wax, and then need to go through a degassing process. There are three types of degassing devices, one is an ordinary stirring reaction device, but Such a device has a slow degassing speed, unstable product quality, and small production capacity. The other is the tube falling film degassing tower. Although the production capacity is large, the degassing tower is not suitable for high-viscosity materials, and the metal material The resulting tower body has poor corrosion resistance and operates elastic pins. There is also a tower degassing tower. Although the material is stable, the corrosion resistance is poor and heat transfer is difficult.
