Heat recovery device

Technical Field

The utility model belongs to the technical field of heat recovery, and specifically relates to a heat recovery device.

Background technique

With the advancement of modern life, a large amount of waste brought about by production and consumption activities threatens the human living environment. Due to technical limitations, there will be a large amount of heat that is not reasonably utilized in the production process. Therefore, heat recovery devices play an important role in the production process.

After checking the public (announcement) number: CN211120740U, a heat recovery device for heat energy and power engineering is disclosed. This technology discloses "including a base and a body, the bottom of the body is fixedly connected to the top of the base, the interior of the body includes a heat-conducting glass plate, a heat-collecting cover, a heat-conducting main pipe and a heat-conducting branch pipe, and the left and right sides of the heat-conducting glass plate are respectively fixedly connected to the inner walls of the left and right sides of the body. The heat recovery device for heat energy and power engineering, by setting a heat-conducting glass plate, a heat-collecting cover, a heat-conducting main pipe and a heat-conducting branch pipe, makes the device collect heat energy inside the body when in use, and part of the heat energy is located at the bottom of the body, and then part of the heat energy enters the interior of the heat-conducting main pipe and the heat-conducting branch pipe through the heat-collecting cover, and has the effect of increasing the contact area between water and heat energy at the top of the device through the heat-conducting glass plate, the heat-conducting main pipe and the heat-conducting branch pipe, so that the heat energy is more easily absorbed by water, thereby improving the heat recovery efficiency of the device and other technical effects";

In the above-mentioned comparative documents, when recovering heat energy, although the contact area between water and heat energy is increased, and the efficiency of water absorbing heat energy is improved, the water is in a static state when absorbing heat energy.

At the same time, during the recovery process, the heat energy cannot be converted into another energy source, thereby greatly increasing energy consumption;

In order to solve the above problems, a heat recovery device is proposed in the present application.
