2results about How to "Control supply" patented technology

This disclosure provides a method for controlling carbon dioxide concentration, a carbon dioxide solution generating device, and related equipment, relating to the field of electrical control technology. The carbon dioxide solution generating device is used to provide a carbon dioxide solution containing carbon dioxide gas and water. The carbon dioxide concentration control method is used to control the carbon dioxide concentration of the carbon dioxide solution provided by the carbon dioxide solution generating device. It collects the actual gas pressure of the carbon dioxide gas, the actual temperature of the water, and the actual volume concentration of carbon dioxide in the carbon dioxide solution formed by mixing the carbon dioxide gas and water. Based on these parameters, the carbon dioxide supply of the carbon dioxide solution generating device is controlled. This disclosure enables more precise control of the carbon dioxide concentration in the carbon dioxide solution provided by the carbon dioxide solution generating device.

This invention belongs to the field of reactor technology and discloses an olefin polymerization reactor with a discharge port at the bottom. It includes: a stirring device, a gas distribution device, a feeding system, an internal cooling system for heat removal, and an external circulation system for heat removal located outside the reactor. The stirring device extends into the reactor. The feeding system consists of a feed pipe installed from the top to the bottom of the reactor. The gas distribution device consists of an inlet pipe installed from the top to the bottom of the reactor. The internal cooling system is located around the gas distribution device. The external circulation system is a jacket located outside the reactor. The feed pipe and the inlet pipe are detachable. This invention effectively solves the problem of material agglomeration and reduced reaction rate caused by the inability to quickly remove heat during the reaction due to exothermic reactions. It enhances heat exchange, improves reaction efficiency, stabilizes production, and significantly reduces maintenance costs.
