Problems solved by technology

However, in the process of pressurization, the delivery gas pressure is unstable due to the diversion of nitrogen-hydrogen mixed gas, and the control strength and operating range of manual operation are different, which will lead to large fluctuations in the pressure and flow rate of nitrogen-hydrogen mixed gas output by the purifier. , which has a serious impact on the entire glass production process

Abstract

The invention discloses a purifier switching method and a storage medium, wherein the purifier switching method includes the following steps: receiving a switching instruction, controlling the switching device to allow the spare adsorption cylinder to communicate with the regeneration gas pipeline, The backup adsorption cylinder is fed with regeneration gas; the first air pressure in the standby adsorption cylinder and the second air pressure in the main adsorption cylinder are obtained; when the absolute value of the difference between the first air pressure and the second air pressure is less than When it is equal to the set value, control the switching device to disconnect the standby adsorption cylinder from the regeneration gas pipeline, and at the same time allow the standby adsorption cylinder to communicate with the mixed gas pipeline, and the standby adsorption cylinder is fed with mixed gas . Through the optimization of the purifier switching process, a stable mixed gas can still be provided during the purifier switching process.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a purifier switching method and a storage medium. Background technique [0002] In the float glass production process, it is necessary to use a purifier to purify the mixed gas after liquid ammonia is decomposed. The purifier used in this purification process is generally composed of two adsorption cylinders. Switch to fill the used adsorption cylinder with nitrogen, so that the adsorbent molecular sieve that has been saturated and adsorbed in the cylinder can be heated and regenerated, and reused in the purification process. [0003] In order to realize the switching between the two adsorption cylinders, in the prior art, the mixing inlet valve of the spare cylinder is usually opened first, so that part of the nitrogen-hydrogen mixture leading to the use cylinder is passed into the spare cylinder, so as to realize the filling of the spare cylinder. pressure. However, ...
