Description
Technical Field
[0001] The utility model relates to the technical field of heat supply and insulation in boiler rooms, and particularly to a heat supply and insulation system for recycling the heat source of boiler blowdown. Background Technique
[0002] As an important facility for providing steam and heat energy, the stable operation and equipment protection of boiler rooms are crucial. However, under cold climate conditions, traditional heat supply and insulation measures in boiler rooms usually rely on external heat insulation materials and heating equipment, but these methods have problems such as high energy consumption, unstable effects, and high maintenance costs. Especially for some places located in cold regions or with extremely low winter temperatures, conventional heat supply and insulation means are often difficult to effectively guarantee the temperature inside the boiler room, resulting in situations such as frozen feed water pipes and malfunction of dosing equipment, seriously affecting the normal operation of the boiler room. At the same time, a large amount of blowdown water is generated during the operation of the boiler, and this part of the blowdown water usually carries a relatively high amount of heat. However, in previous operations, this part of the heat has often not been effectively utilized but directly discharged, causing waste of energy. Content of the Utility Model
[0003] The purpose of the utility model is to provide a heat supply and insulation system for recycling the heat source of boiler blowdown, which is used to solve the problems of high energy consumption, unstable effects, and high maintenance costs during the internal heat supply and insulation of existing boiler rooms.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A heat supply and insulation system for recycling the heat source of boiler blowdown, including a boiler and a heat supply and insulation system used in cooperation with the boiler. The heat supply and insulation system includes a flash tank connected to the continuous blowdown port of the boiler, a first water storage tank connected to the drain outlet of the flash tank, a pipeline connected to the steam outlet of the flash tank, a second water storage tank arranged on the pipeline, and a heat supply and insulation component arranged in the boiler room; both the first water storage tank and the second water storage tank are connected to the heat supply and insulation component, and a reversing valve is arranged at the connection.
[0005] Further, the part of the pipeline located inside the second water storage tank is distributed in a serpentine shape.
[0006] Further, a discharge pool is connected to the heat supply and insulation component.
[0007] Further, the heat supply and insulation component includes a plurality of radiators, and the plurality of radiators are connected in series with each other.
[0008] Further, a filter and a water softener are sequentially arranged between the flash tank and the first water storage tank.
[0009] Further, a pressure pump is arranged between the reversing valve and the heat supply and insulation component.
[0010] Furthermore, a stop valve is provided between the boiler and the drain expansion tank.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. The high-temperature sewage discharged from the continuous sewage outlet of the boiler enters the drain expansion tank, the pressure is reduced and the steam and water are separated through the drain expansion tank, the separated sewage with temperature enters the first water storage tank, and the separated steam is discharged through the pipeline, and a part of the pipeline is located in the second water storage tank. When the steam is discharged, the clean water source in the second water storage tank can be heated, so that the liquids in the first water storage tank and the second water storage tank both have temperature. The first water storage tank and the second water storage tank are both connected to the heating and insulation components, so the heating and insulation components can be heated by the sewage in the first water storage tank first to achieve heating and insulation of the boiler room. Since the sewage in the first water storage tank contains impurities, the heating and insulation components can be heated by the clean water source in the second water storage tank after a period of use, which can be used for heating and insulation of the boiler room, and can also be used to flush the inside of the heating and insulation components to extend the service life of the heating and insulation components;
[0013] 2. The device treats the high-temperature sewage discharged from the continuous sewage outlet of the boiler and uses it to heat the boiler room to prevent the normal operation of the boiler room from being affected by freezing of the water supply pipe and failure of the dosing equipment.
