A high-low pressure steam mixing heat pump

Abstract

This application discloses a high-low pressure steam mixing heat pump, including a pump body. The pump body has an inlet chamber, a mixing chamber, and a diffusion chamber. The inlet chamber includes a high-pressure inlet chamber and a low-pressure inlet chamber, through which high-pressure steam and low-pressure steam are respectively introduced. A nozzle is opened at the end of the inlet chamber, which is connected to the mixing chamber. The high-pressure steam and low-pressure steam are mixed in the mixing chamber. The mixing chamber is connected to the diffusion chamber, and a diffusion port is opened at the end of the diffusion chamber, which is connected to the outside of the pump body. After the high-pressure steam and low-pressure steam are mixed, they enter the diffusion chamber and are ejected from the pump body through the diffusion port. The application also includes a valve, which includes a plug located in the pump body and movably disposed at the nozzle of the inlet chamber. The flow rate of the high-pressure steam and low-pressure steam ejected from the nozzle is controlled by moving the plug. The high-low pressure steam mixing heat pump designed in this scheme ensures effective mixing of high and low pressure steam and improves the ejection effect of heat pump steam by setting a valve at the connection between the high-low pressure inlet chamber and the mixing chamber and controlling the high and low pressure steam entering the mixing chamber through the plug of the valve.

Description

Technical Field

This device achieves pressure boosting and heat recovery by using high-pressure steam to eject low-pressure steam. Traditional steam jet heat pumps do not have valves in their internal chambers to regulate the flow of high and low-pressure steam, resulting in uneven mixing of high and low-pressure steam and poor diffusion steam ejection effect.
