Description

Steam Heat Recovery System

technical field

The utility model relates to a recovery device for recovering heat energy in steam, in particular to a system for introducing steam into a heat storage solution in a accommodating tank, and further recovering heat energy through a spray system.

Background technique

High temperature steam contains a lot of heat energy. Therefore, a recovery system is required to recover the heat energy. In the prior art, the high temperature steam is passed into the heat storage solution, which is generally liquid water, and the heat energy in the high temperature gas is recovered through the heat storage capacity of the water. However, because water vapor contains a large amount of non-condensable gas, the gas containing heat energy will be separated from the heat storage solution and enter the environment, which cannot effectively improve the recovery efficiency of heat energy. The reason for the generation of non-condensable gas is due to the physical properties of the dew point that the gas has. Dew point, also known as dew point temperature, in meteorology refers to the temperature at which the gaseous water contained in the air reaches saturation and condenses into liquid water under a fixed air pressure. At this temperature, the condensed water floating in the air is called fog, and when it touches a solid surface, it is called dew, hence the name dew point.

To this end, we need to adopt a system that can recover the heat energy of the mist containing heat energy floating in the recovery system to improve the efficiency of heat recovery.

Still further, the spray head structure of the atomizing spray device is provided with a pressure return device, which includes a main body part, a water blocking plate and a matching spring arranged on the main body part. When the water pressure entering the main body increases, the spring is compressed and deformed, the water baffle moves down, and the outlet section becomes larger; when the pressure becomes smaller, the water baffle moves and the outlet section becomes smaller. This can make the spray more uniform and form a curved spray area to improve interactivity.
