Description

Technical Field

[0001] This utility model relates to the field of steam boiler technology, and in particular to a waste heat recovery component for steam boilers. Background Technology

[0002] A steam boiler is a device that heats water into steam and is widely used in industrial production and heating systems. They generate heat by burning fuels (such as coal, oil, natural gas, etc.) or using other energy sources (such as electricity), which in turn heats the water inside the boiler, turning it into steam. Steam can be used to drive steam turbines to generate electricity, power industrial equipment, provide heat for heating and drying processes, or be used in heating systems.

[0003] After a steam boiler is used, the waste heat inside the boiler is difficult to recover, resulting in energy waste. Therefore, this utility model proposes a waste heat recovery component for steam boilers to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a waste heat recovery component for steam boilers.

[0005] To achieve the above objectives, this utility model provides a waste heat recovery component for a steam boiler, including a waste heat storage tank. A first heat insulation pipe is fixedly installed through one side of the waste heat storage tank. An installation shell is fixedly installed through the end of the first heat insulation pipe away from the waste heat storage tank. An exhaust fan is fixedly installed inside the installation shell. A second heat insulation pipe is fixedly installed through the side of the installation shell away from the first heat insulation pipe. A steam boiler is fixedly connected through the end of the second heat insulation pipe away from the installation shell. A first electric valve is installed on the second heat insulation pipe. A third heat insulation pipe is fixedly installed through the side of the waste heat storage tank away from the first heat insulation pipe. A second electric valve is installed on the third heat insulation pipe.

[0006] Furthermore, the waste heat storage box includes a thermal insulation layer, a waterproof layer is fixedly provided on the outer side of the thermal insulation layer, and a heat-resistant layer is fixedly provided on the inner side of the thermal insulation layer.

[0007] Furthermore, support rods are fixedly installed at the upper and lower ends of the inner side of the mounting shell, and the end of the support rod away from the mounting shell is fixedly connected to the waste heat storage box.

[0008] Furthermore, a fourth heat-conducting pipe is detachably and sealed to the end of the third heat insulation pipe away from the waste heat storage box. The fourth heat-conducting pipe passes through the heating box and is fixedly connected to the heat-conducting pipe through a connector.

[0009] Furthermore, the heat-conducting pipe is wound in an arc shape inside the heating box, and the top end of the heat-conducting pipe penetrates the heating box and extends upward.

[0010] Furthermore, a steam pipe is fixedly installed through one side of the top of the heating box, and a temperature sensor is fixedly installed on the inner wall of the heating box. The temperature sensor is electrically connected to a temperature controller, and the temperature controller is electrically connected to the second electric valve.

[0011] Furthermore, the heating chamber is provided with a switch door on the front, and a sealing ring is fixedly fitted on the fourth heat conduction pipe, which is sealed and fixedly installed on the outer wall of the heating chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By using a structure consisting of a first thermal insulation pipe, an exhaust fan, a second thermal insulation pipe, and a second electric valve, the first electric valve is opened, the second electric valve is closed, and the exhaust fan is started to draw the waste heat from the steam boiler into a waste heat storage tank. The waste heat storage tank stores the waste heat. The mounting shell is fixedly connected to the waste heat storage tank by a support rod. The thermal insulation layer improves the thermal insulation performance of the waste heat storage tank, the waterproof layer improves the waterproof performance of the waste heat storage tank, and the heat-resistant layer improves the heat resistance of the waste heat storage tank. This solves the problem of energy waste caused by the difficulty in recovering the waste heat inside the steam boiler after use.

[0014] 2. Through the structure of a fourth heat-conducting pipe, a temperature sensor, a second electric valve, and a sealing ring, the sealing ring is fixedly installed on the fourth heat-conducting pipe and sealed on the outer wall of the heating box, which improves the sealing performance of the connection between the fourth heat-conducting pipe and the heating box. When it is necessary to utilize the waste heat, the second electric valve is opened, and the waste heat enters the heat-conducting pipe to heat the object to be heated inside the heating box. The temperature sensor senses the temperature inside the heating box. When the temperature reaches a certain value, the temperature sensor sends a signal to the temperature controller, which controls the second electric valve to close, so that the heating temperature is maintained within a certain range.
