Abstract

The invention discloses a control apparatus for a methanol recovery tower reboiler, and relates to the technical field of dimethyl ether production. The apparatus comprises a steam pipe and the methanol recovery tower reboiler, wherein a first ball valve, an electric control valve, a second ball valve and a flowmeter are sequentially arranged between the steam pipe and the methanol recovery tower reboiler in a direction from the steam pipe to the methanol recovery tower reboiler; a liquid level sensor is arranged inside the methanol recovery tower reboiler and is connected with signal treatment device; and the signal treatment device is also respectively connected with the flowmeter and the electric control valve. The control apparatus has the advantages that through the real-time monitoring on the liquid level height of the methanol recovery tower reboiler, the steam supply quantity is automatically regulated, and the steam waste caused by solution insufficiency or no solution in the reboiler is avoided.

Description

technical field [0001] The invention relates to the technical field of dimethyl ether production, in particular to a control device for a methanol recovery tower reboiler. Background technique [0002] Due to the increasing demand for energy and the increasing awareness of environmental protection, dimethyl ether, as a clean fuel, has been paid more and more attention to its high-efficiency, energy-saving and environmentally friendly combustion technology. Dimethyl ether is a colorless gas with a slight ether aroma, which is inert, non-corrosive, easy to compress, condense, and vaporize. From the analysis of the combustion mechanism of dimethyl ether, under the same heat conditions, compared with other gases such as natural gas and liquefied petroleum gas, the combustion efficiency of dimethyl ether can be increased by about 5%. DME has been widely used in automobile fuel and domestic fuel, and it is also a potential new industrial fuel with broad application prospects. ...
