Description

Technical Field

[0001] The utility model relates to a heating and supplementary heat system, in particular to a heat supply pipe network return water heating and supplementary heat system, belonging to the technical field of heating. Background Art

[0002] The heating network is composed of multiple heating pipes that start from the boiler room, direct-fired machine room, heating center, etc., and lead from the heat source to the heat entrance of the building. The heating network is a branch-like pipeline system arranged according to the urban heat load distribution, block status, development plan, and geological and topographic conditions.

[0003] In order to ensure the long-distance transmission effect of the heating pipeline network, a high-temperature and high-pressure working state will be maintained. The user's indoor heating system cannot withstand such high-temperature and high-pressure working parameters, and high water temperature poses a great safety hazard. Therefore, the primary network water for heating cannot be directly supplied to users. The secondary network directly provides the required heat to the user's room. The temperature and pressure are lower than those of the primary network, which are the working parameters that the user's indoor system can withstand.

[0004] The primary network is responsible for transporting hot water from the heat source to the heat exchange station, while the secondary network delivers the lower temperature hot water obtained at the heat exchange station to various heat users to meet their heating needs. The amount of heat that can be provided by the thermal pipes of the secondary network directly determines the user experience and the heating effect of the entire community. If the heat that can be provided by the thermal pipes of the secondary network cannot meet the needs of the user, the heating will need to be supplemented by secondary heating, and the return water needs to be heated to improve the efficiency and stability of the heating system.

[0005] The return water temperature is raised to improve the efficiency and stability of the heating system, and supplementary heat is provided to ensure that the hot water supply at the user end meets the set temperature requirements. To this end, a return water heating and supplementary heat system for the heating pipe network is proposed. Utility Model Content

[0029] The embodiment of the utility model provides a heat supply pipe network return water heating and supplementary heat system.

[0031] Please refer to Figure 1 and Figure 3 A heat supply mechanism 2 is connected between the secondary network 104 and the user heating equipment 105 through a pipe 106, and a heat supply mechanism 2 is connected between the user heating equipment 105 and the heat source 101. The two ends of the heat supply mechanism 2 are connected to the pipe 106 through a connecting component 4. The heat supply mechanism 2 includes a heating pipe 201, and an electromagnetic coil 202 is provided on the side of the heating pipe 201. The electromagnetic coil 202 is outer-coated with a glass wool insulation layer 203, which can play a role in thermal insulation. The heat supply mechanism 2 also includes two heating plates 204 fixedly connected to the inner wall of the heating pipe 201, and the two heating plates 204 are cross-arranged on the inner wall of the heating pipe 201.

[0032] After the electromagnetic coil 202 is connected to the AC power supply, the electromagnetic coil 202 and the heating tube 201 cooperate with each other to heat the hot water flowing inside the heating tube 201 through the electromagnetic heating principle. The heating plate 204 can be heated by the heating tube 201, thereby increasing the heating of the water in the middle part of the heating tube 201. A heat supplement mechanism 2 is connected between the secondary network 104 and the user heating equipment 105 through the pipeline 106, which can heat the hot water delivered to the user heating equipment 105 to ensure that the hot water supply at the user end meets the set temperature requirements.

[0033] The principle of electromagnetic heating is to generate an alternating magnetic field through the components of the electromagnetic coil 202. When the iron-containing heating tube 201 is placed on it, the surface of the heating tube 201 cuts the alternating magnetic lines of force, generating alternating eddy currents in the metal part of the heating tube 201. The eddy currents cause the iron atoms of the heating tube 201 to move irregularly at high speed. The atoms collide and rub against each other to generate heat energy, thereby achieving a heating effect.

The electromagnetic coil installation hole 302 is provided to facilitate the installation of the electromagnetic coil 202, and the ventilation hole 303 can provide ventilation.

[0036] Please refer to Figure 4 The connecting component 4 includes a first flange 401 fixedly installed at one end of the heating pipe 201, and a second flange 402 is fixedly installed at one end of the pipeline 106 close to the heating pipe 201.

The device and the pipeline 106 can be connected by the matching arrangement of the first flange 401, the second flange 402 and the flange gasket 403.

[0037] Working principle: First, the heating tube 201 and the pipeline 106 are connected through the first flange 401, the second flange 402 and the flange gasket 403, and then the electromagnetic coil 202 is connected to the AC power supply.
