Acetylene gas recovery device for producing alkylphenol acetylene tackifying resin

Abstract

The invention provides an acetylene gas recovery device for producing alkylphenol acetylene tackifying resin, and mainly relates to the field of chemical equipment. The acetylene gas recovery device for producing the alkylphenol acetylene tackifying resin comprises a reaction kettle, wherein a gas adding pipe and a gas discharging pipe are arranged on the reaction kettle, the gas discharging pipe is connected with a first gas conveying pipe, the first gas conveying pipe is connected with a temperature control heat exchange device, the temperature control heat exchange device comprises a shell, a heat exchange core body is fixedly installed in the shell, a gas inlet pipe is arranged on one side of the shell and fixedly connected with the first gas conveying pipe, a gas outlet pipe is arranged on the upper portion of the shell, a heat exchange medium inlet pipe is arranged on the upper portion of the heat exchange core, and a heat exchange medium outlet pipe is arranged on the lower portion of the heat exchange core. The acetylene gas recovery device has the beneficial effects that the temperature of components such as the heat exchange device can be controlled, so high and stable gas recovery efficiency is ensured, and the requirement for recovery of industrial production acetylene gas can be better met.

Description

technical field [0001] The invention mainly relates to the field of chemical equipment, in particular to an acetylene gas recovery device for producing alkylphenol acetylene tackifying resin. Background technique [0002] At present, the concept of "lucid waters and lush mountains are golden mountains and silver mountains" has been deeply rooted in the hearts of the people. While enterprises are in safe production, environmental protection management is also an urgent task. In view of the characteristics of the "three wastes" in chemical production, how to recycle and reuse waste residue, waste gas and waste water in an effective way can effectively reduce the cost of products for enterprises, reduce environmental pollution, improve economic and social benefits of enterprises, and enhance the competitiveness of enterprises are all significant. [0003] Rubber tackifying resin is one of the important additives in the rubber processing process. Its main function is to improve...

Problems solved by technology

The disadvantage of this kind of production equipment is: because the acetylene gas after the reaction has no safety recovery device when the pressure is released, it not only causes the waste of acetylene gas, but also causes explosion accidents because of the flammable and explosive properties of acetylene gas. Serious will cause property damage or personal injury

The reaction in the reactor is a high-temperature and high-pressure reaction. The gas generated by the reaction contains a large amount of high-temperature water vapor. If the water vapor cannot be removed in time, it will affect the removal of impurities and the drying of the gas. For example, excessive high-temperature water vapor enters the gas for a long time The impurity removal solution will cause the solution to boil, and the desiccant will soon be saturated and cannot continue to absorb water, so it cannot meet the high-efficiency recovery of acetylene gas.
