Problems solved by technology

[0002] In the prior art, N-methyldiethanolamine is manufactured by heating ethylene oxide and monomethylamine. In the whole process, a two-stage evacuator system is required, the first stage is a water ring evacuator, and the second stage is a water ring evacuator system. It is a steam evacuator, which consumes a lot of energy and has a complicated system; in the follow-up waste water from the manufacture of N-methyldiethanolamine, it will contain a large amount of monomethylamine, which wastes resources and increases production costs

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, a rectification vacuum system for a desulfurizer device according to the present invention includes a reflux tank 1, the reflux tank 1 is connected to the anti-scouring safety tank 2 through a pipeline, and the anti-scouring safety tank 2 is connected to the anti-scouring safety tank 2 through a pipeline. Dry screw vacuum pump 3 is connected, and described dry screw vacuum pump 3 is connected with water tank 4 through pipeline; Described dry screw vacuum pump 3 has three, they are arranged in parallel; The power of described dry screw vacuum pump 3 is 30kw. The components of the present invention are closely matched and connected, and the operation is safe and reliable. Three dry-type screw vacuum pumps are used to replace the water ring evacuator and the steam evacuator, which not only simplifies the production system,...

Abstract

The invention relates to a rectification vacuum-pumping system of a desulfurizer device. The system comprises a reflux tank which is connected with an anti-impact safety tank through a pipeline. The anti-impact safety tank is connected with a dried screw vacuum pump through a pipeline. The dried screw vacuum pump is connected with a water tank through a pipeline. The system provided by the invention saves steam, and subsequent wastewater contains low content of monomethylamine, so that the whole system is simplified.

Description

technical field [0001] The invention relates to a vacuum treatment system, in particular to a rectification vacuum treatment system. Background technique [0002] In the prior art, N-methyldiethanolamine is manufactured by heating ethylene oxide and monomethylamine. In the whole process, a two-stage evacuator system is required, the first stage is a water ring evacuator, and the second stage is a water ring evacuator system. It is a steam evacuator, which consumes a lot of energy and has a complex system; in the subsequent waste water of manufacturing N-methyldiethanolamine, it will contain a large amount of monomethylamine, which wastes resources and increases production costs. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a rectification and vacuum system for desulfurizer devices that saves steam, has a low amount of monomethylamine in the follow-up waste water, and s...
