Detailed Description
The present invention will be described in further detail with reference to specific embodiments in order to make the technical field better understand the scheme of the present invention.
As shown in fig. 1, a boiler conversion device comprises a boiler 1, an energy storage pipeline 2, a heat exchange station 3, a plurality of electric valves 4-7 and pipelines for connecting the above components.
The water outlet of the boiler 1 is divided into two paths, one path is connected with the water inlet of the primary net 3, and the other path is connected with the water inlet of the energy storage pipeline 2 through an electric valve 5.
The water outlet of the heat exchange station 3 is divided into two paths, one path is connected with the water inlet of the boiler 1, and the other path is connected with the water inlet of the energy storage pipeline 2 through an electric valve 7.
The water outlet of the energy storage pipeline 2 is divided into two paths, one path is connected with the water inlet of the boiler 1 through an electric valve 4, and the other path is connected with the water inlet of the primary net 3 through an electric valve 6.
When the electric valves 4-7 of the boiler conversion device of the present invention are operated, the electric valves 4 and 5 are simultaneously opened or closed, and the electric valves 6 and 7 are simultaneously opened or closed.
The boiler conversion device can realize three sets of circulating pipelines by controlling the opening and closing of the electric valves 4-7, and the three sets of circulating pipelines are respectively as follows:
a first circulating pipeline: all the electric valves 4-7 are closed, the water outlet of the boiler 1 is connected with the water inlet of the primary net 3 through a pipeline, and the water outlet of the primary net 3 is connected with the water inlet of the boiler 1 through a pipeline. Therefore, the first circulation pipeline is a circulation mode of the boiler in a normal working state, other valves are closed at the moment, the effluent of the boiler 1 is cooled after heat exchange of the primary network 3 heat exchange station and then returns to the boiler 1, and water circulation of the heat exchange station is achieved.
And a second circulating pipeline: the electric valves 4 and 5 are opened, the electric valves 6 and 7 are closed, and the effluent of the boiler 1 enters the energy storage pipeline 2 through the electric valve 5 and returns to the boiler 1 through the electric valve 4. Therefore, the second part of the circulation pipeline is an energy storage circulation, when the heat generated by the boiler 1 in the standard operation state is excessive, the valves 4 and 5 are opened, and at the moment, a part of the hot water in the boiler 1 enters the energy storage pipeline 2 to store the heat.
A circulating pipeline III: electric valves 4 and 5 are closed, electric valves 6 and 7 are opened, and the effluent of the energy storage pipeline 2 enters the heat exchange station 3 through the electric valve 6 and returns to the energy storage pipeline 2 through the electric valve 7. Therefore, the third circulating pipeline is a heat supply circulation of the storage pipeline, and when the heat generated by the boiler in the standard operation state is insufficient, the second circulating pipeline can be opened again to supply heat; of course, it is also possible to reduce the standard load of the boiler (e.g. from 50% to 30%) and then to supplement the heat with energy storage pipes.
The energy storage pipe 2 is a tubular structure, and the schematic end view thereof is shown in fig. 2. The inner side of the energy storage pipeline 2 is a flowing medium pipeline 203, and the outer side is an energy storage material pipeline 207; a fluid medium 205 flows through the fluid medium pipe 203, and the material of the fluid medium pipe 203 is determined by the use of the fluid medium 205; the material of the flow medium 205 is determined by the actual boiler operating conditions.
An energy storage material 204 is filled between the flowing medium pipe 203 and the energy storage material pipe 207. The energy storage material 204 is used to store energy, and its material is determined according to the specific application. The outer side of the energy storage material pipeline 207 is wrapped by an outer insulating layer 201 which is made of an insulating material and plays a role in insulating the energy storage pipeline 2 so as to isolate the temperature conduction inside and outside the energy storage pipeline 2.
The outer side of the flowing medium pipe 203 is also provided with a plurality of heat conducting fins 202 which are fixed on the outer side of the flowing medium pipe 203. The heat conducting fins 202 are in direct contact with the energy storage material 204, which can increase the heat conducting area and speed of the flow medium 205 and the energy storage material 204, the number of the heat conducting fins 202 depends on the diameter and length of the flow medium pipe 203, and the heat conducting fins 202 may be arranged radially or axially on the flow medium pipe 203.
As shown in fig. 3, the tubular energy storage pipeline 2 can directly replace a heat supply pipeline between the existing boiler 1 and the heat exchange station 3, that is, the boiler 1 and the heat exchange station 3 are connected through the tubular energy storage pipeline 2. By changing the heat supply pipeline into the tubular energy storage pipeline 2, the energy storage pipeline 2 stores certain energy during heating, and when the boiler 1 breaks down for a short time and needs to be shut down for maintenance, the heat stored in the energy storage pipeline 2 can continue to supply heat for the short time; in addition, because certain energy is stored in the energy storage pipeline 2, the heating temperature is basically stable, and the energy storage pipeline is suitable for occasions with high constant temperature requirements.
The inventive concept is explained in detail herein using specific examples, which are given only to aid in understanding the core concepts of the invention. It should be understood that any obvious modifications, equivalents and other improvements made by those skilled in the art without departing from the spirit of the present invention are included in the scope of the present invention.
