Reaction kettle for synthesizing scale and corrosion inhibitor from allantoin production effluent

Abstract

The invention relates to a reaction kettle for synthesizing scale and corrosion inhibitors from allantoin production waste liquid, which is characterized in that it includes a reaction kettle body, an inner jacket, an outer jacket, a condenser, a cooling liquid storage tank, Cooling liquid replenishment tank, gas absorption tank and controller, the reactor body is provided with an inner jacket and an outer jacket, the top of the reactor body is provided with a feeding port, and the top of the reactor body is connected to a condensing The top of the condenser is connected to the gas absorption tank through a pipeline, and the cooling liquid storage tank is connected to the cooling liquid replenishment tank through a circulation pipeline. The reaction kettle has precise temperature control and high reflux efficiency. Absorption, high synthesis efficiency, clean and environmentally friendly synthesis process, can meet production needs.

Description

technical field [0001] The invention belongs to the fields of water treatment industry and environmental protection, and in particular relates to a reactor for synthesizing scale and corrosion inhibitors from allantoin production waste liquid. Background technique [0002] Scale and corrosion inhibitors are commonly used in circulating cooling water systems at home and abroad to prevent scaling on heat exchange surfaces and prevent equipment corrosion. Organic phosphine scale and corrosion inhibitors have played an important role in the water treatment industry. At present, energy saving and emission reduction have been valued by the whole society, which has promoted the popularization and application of scale and corrosion inhibitors in various industries. With the continuous expansion of the water treatment agent market, manufacturers and users hope to develop more cost-effective scale and corrosion inhibitors. The corrosion and scale inhibition properties of the products...

AI Technical Summary

Problems solved by technology

[0004] In the process of using allantoin to produce waste liquid to synthesize scale and corrosion inhibitors, the temperature needs to be strictly controlled. At the same time, since the solvent reflux is required during the synthesis process, the speed of solvent reflux also directly affects the synthesis efficiency. The existing reactor Can not meet the needs of allantoin production waste liquid synthetic scale and corrosion inhibitors
