Description

Technical Field

[0001] The utility model relates to the technical field of exhaust steam recovery, in particular to an exhaust steam recovery device. Background Art

[0002] There are various ways to generate exhaust steam, which is generally steam that needs to be discharged after the equipment is used. The Chinese utility model patent with publication number CN217275667U discloses an exhaust steam recovery device for air discharge, including a shell with an open bottom and a motor installed on the shell. The motor is connected to the exhaust steam condensation recovery structure in the shell and electrically rotates the exhaust steam condensation recovery structure to generate negative pressure. The exhaust steam enters the recovery device from the bottom of the shell. The recovered exhaust steam falls to the bottom of the shell along the inner wall of the shell after centrifugal action and is recovered through the water outlet. After the exhaust steam is recovered, heat can be extracted through the heat exchange equipment to improve the heat utilization rate; and after the heat is extracted, the condensed water can be returned to the process system for repeated use, reducing water resource consumption. A detachable centrifugal plate design is adopted for easy maintenance. An adsorption layer, such as lining cloth, fiber, sponge and other materials, can be set on the inner wall of the shell.

[0003] However, the shell is open at the bottom and closed at other positions to collect exhaust steam. When the cooling water pipe outputs water flow to guide the exhaust steam through the water spray seams or holes, the circulation slot is in a rotating state. Part of the water flow in the cooling water pipe will touch the intervals between the groups of circulation slots and cannot enter the circulation slots, and will drip through the bottom opening of the shell, which is not only likely to affect the flow direction of the exhaust steam discharged below and the discharge equipment, reducing the exhaust steam recovery efficiency, but also there is excessive waste of cooling water.
