Detailed Description
In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.
Fig. 1 is a schematic structural diagram of a boiler flue heat recovery device provided by the present invention; as shown in FIG. 1, the embodiment of the present invention provides a boiler flue heat recovery device, including: a heat recovery tank 7, a water storage tank 6 and a water pump 8.
The heat recovery tank 7 is covered on the flue of the boiler 1. The heat recovery tank 7 and the water storage tank 6 are filled with water. The tank body of the heat recovery tank 7 is made of stainless steel, so that heat absorption is facilitated. The flue inlet 2 of the boiler 1 penetrates into the heat recovery tank 7, and the flue outlet 3 of the boiler 1 penetrates out of the heat recovery tank 7. When the boiler 1 is operated by combustion, the flue generates heat, which heats the water in the heat recovery tank 7.
The hot water outlet 4 of the heat recovery tank 7 is communicated with the water storage tank 6; the water storage tank 6 is communicated with a cold water inlet 5 of a heat recovery tank 7 through a water pump 8; the water storage tank 6 is externally connected with hot water using equipment, and the water storage tank 6 is also externally connected with a water inlet pipe for storing water. The hot water using apparatus includes: a heating device 9, a shower device 10, etc. In this embodiment, the spiral fin is arranged inside the heat recovery tank 7, so that water in the heat recovery tank 7 can be fully stirred, and uniform heat exchange is realized.
The tank body of the heat recovery tank 7 is provided with a heat preservation and insulation device. The boiler flue heat recovery device of this embodiment collects heat and recycles in integrative system, and the jar body of heat recovery jar 7 sets up heat preservation heat-proof device, can retrieve the heat as far as possible in the jar body. The more heat is collected, the more stable the temperature is maintained and the more heat energy is consumed that can be converted and stored for use in the next functional zone.
The embodiment of the utility model provides a pot burning heat recovery theory of operation: when the boiler 1 works in a combustion mode, the flue generates heat, and water in the heat recovery tank 7 can be heated by utilizing the heat of the flue so as to recycle the heat. The heat recovery tank 7 is provided with a water storage tank 6 by cold water entering from a cold water inlet 5 at the lower part and supplying from a hot water outlet 4 at the upper part, and the water storage tank 6 can lead water into the heat recovery tank 7 through a water pump 8 to carry out water circulation. The rivers in the storage water tank 6 flow into heat recovery jar 7, and the heat that the flue gived off all around can become hot cold water very soon, and hot water flows out from hot water outlet 4 of heat recovery jar 7, returns storage water tank 6 and concentrates the back of storing, can supply with hot water user equipment such as heating equipment 9 and shower equipment 10, utilizes.
In this embodiment, temperature sensors may be disposed in the heat recovery tank 7 and the water storage tank 6, respectively, and control and parameter setting may be performed by an external controller. When the water temperature in the heat recovery tank 7 reaches the preset water temperature, the electromagnetic valve of the hot water outlet 4 is controlled to be opened, and hot water is supplied to the water storage tank 6; when the water temperature in the water storage tank 6 reaches the preset water temperature, controlling an electromagnetic valve connected with hot water using equipment to be opened, and supplying hot water to the hot water using equipment; when the water temperature in the water storage tank 6 is lower than the preset water temperature, the water pump 8 is controlled to work, and cold water is introduced into the heat recovery tank 7 for heating.
