Water vapor recovery device for high-pressure reaction kettle

Abstract

The invention discloses a water vapor recovery device for a high-pressure reaction kettle. A main body of the device mainly adopts the high-pressure reaction kettle, wherein a water vapor discharge port is formed in the top of the high-pressure reaction kettle and connected with one end of a water vapor discharge pipe through a control valve, the other end of the water vapor discharge pipe is communicated with a water vapor feeding port of a water vapor collection tank, a PLC (programmable logic controller) control box is arranged in any position of the outer side of the water vapor collection tank, the bottom of the water vapor collection tank is connected with a drainage port, the outer side of the drainage port is connected with a drainage pipe through an electromagnetic valve, the water vapor feeding port is formed in the middle of the water vapor collection tank, and a liquid level sensor is arranged on the inner wall of the water vapor collection tank right below the water vapor feeding port. The device can recover water vapor discharged from the high-pressure reaction kettle, reduce water vapor into liquid-state water and then treat the water, repeated utilization of high-pressure water vapor is realized, pollution possibly caused to the surrounding environment in the water vapor discharge process is substantially reduced, and threat of high-pressure water vapor to life safety of an operator is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of hot melt adhesive preparation, in particular to a water vapor recovery device for a high-pressure reactor. Background technique [0002] Hot melt adhesive is a kind of plastic adhesive. Its physical state changes with temperature within a certain temperature range, but its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. Because the product itself is solid, easy to pack, transport, store, solvent-free, non-polluting, and non-toxic; and it has the advantages of simple production process, high added value, strong bonding strength, and fast speed. [0003] Polyester and polyamide are currently the most widely used high-performance polymer hot melt adhesives. Polyester resin is easy to crystallize and has high strength in the crystallized state, which is especially suitable for hot melt adhesives. Polyester hot melt adhesive has the ch...

Problems solved by technology

The usual practice is to directly discharge high-pressure water vapor into the external environment, but this operation will pose a threat to the safety of the operator, and at the same time, due to the presence of a small amount of organic matter in the water vapor, it will cause pollution to the surrounding environment
