Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery, and in particular to an energy recovery device for biomass heat and co-production. Background Technology

[0002] Waste heat recovery, as the name suggests, is the process of recycling and reusing the waste heat generated by equipment to achieve the goal of energy conservation and environmental protection. A certain amount of waste heat is also generated in the process of biomass heat and co-production, so it is necessary to recover and reuse this part of the heat.

[0003] For example, the biomass boiler waste heat recovery and utilization device for clean production disclosed in the authorization announcement number CN 210291942 U absorbs heat from the boiler flue gas by setting up metal heat conduction pipes, pours water into the box, and heats the water inside the box through the metal heat conduction pipes for use by surrounding workers.

[0004] However, relying on a single metal heat pipe for heat exchange results in low overall exchange efficiency and poor heat flow, which can easily lead to uneven heat transfer and cause the discharged water to fluctuate in temperature, causing discomfort. To address this, we propose an energy recovery device for biomass heat and co-production. Utility Model Content

[0005] The purpose of this utility model is to provide an energy recovery device for biomass heat and co-production. By setting up a waste heat utilization mechanism, it is convenient to use the heat exchange components, air inlet pipe and exhaust pipe to achieve heat exchange. In addition, with the addition of a stirring component, the heat distribution is uniform, thereby achieving uniform and rapid heat exchange.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy recovery device for biomass heat and co-production, comprising a heat exchange chamber and a cover located above the heat exchange chamber, wherein a waste heat utilization mechanism is provided inside the heat exchange chamber, the waste heat utilization mechanism comprising:

[0007] A heat exchange assembly is disposed inside the heat exchange chamber and is used for the flow of heat exchange liquid;

[0008] An air intake pipe and an exhaust pipe are provided, wherein the air intake pipe is fixedly connected to one side of the top of the heat exchange box, and the exhaust pipe is fixedly connected to one side of the bottom of the heat exchange box.

[0009] A stirring assembly is disposed inside the heat exchange assembly and is used to agitate the high-temperature flue gas.

[0010] Preferably, the heat exchange assembly includes an inlet pipe fixedly connected to the outer surface of the cover, a heat exchange pipe fixedly connected to one end of the inlet pipe, and an outlet pipe fixedly connected to one end of the heat exchange pipe, with one end of the outlet pipe extending to the outside of the cover.

[0011] Preferably, the heat exchange pipe includes an outer coil connected to the end of the inlet pipe, a connecting pipe fixedly connected to one end of the outer coil, and an inner coil fixedly connected to one end of the connecting pipe, and one end of the inner coil is connected to the end of the outlet pipe.

[0012] Preferably, the stirring assembly includes a rotating shaft rotatably disposed in the middle of the cover, a plurality of stirring blades fixedly connected to the outer surface of the rotating shaft, a plurality of through grooves opened on the top of the stirring blades, concave arc-shaped sides disposed on both sides of the stirring blades, and a stirring motor fixedly connected to one end of the rotating shaft extending to the top of the cover.

[0013] Preferably, the interior of the heat exchange box, the inner side of the cover, and the outer surface of the heat exchange components are all fixedly provided with an anti-corrosion coating.

[0014] Preferably, the inner coil is located inside the outer coil, and both the outer contours of the inner coil and the outer coil are spiral-shaped.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] Flue gas enters the heat exchange chamber through the inlet pipe. At this time, the heat exchange refrigerant or heat exchange liquid enters the heat exchange components and exchanges heat with the high-temperature flue gas inside the heat exchange chamber, thereby heating the heat exchange refrigerant or heat exchange liquid. Finally, the high-temperature flue gas is discharged from the exhaust pipe. At the same time, the stirring component agitates the high-temperature flue gas, thereby accelerating the flow of heat from the high-temperature flue gas and uniformly heating the heat exchange refrigerant or heat exchange liquid, thus avoiding uneven heating. Even when the inlet pipe no longer receives high-temperature flue gas, the high-temperature flue gas inside the heat exchange chamber can still heat the heat exchange liquid or heat exchange refrigerant. The overall heat exchange efficiency is high, thus making full use of the waste heat generated in the biomass heat and co-production process. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figure 1-4 The diagram shows an energy recovery device for biomass heat and co-production. Example

[0024] The system includes a heat exchange chamber 1 and a cover 2 located above the heat exchange chamber 1. The heat exchange chamber 1 houses a waste heat utilization mechanism, which includes: a heat exchange component 3, located inside the heat exchange chamber 1 and used for the flow of heat exchange liquid; an inlet pipe 5 and an outlet pipe 6, the inlet pipe 5 being fixedly connected to one side of the top of the heat exchange chamber 1 and the outlet pipe 6 being fixedly connected to one side of the bottom of the heat exchange chamber 1; and a stirring component 7, located inside the heat exchange component 3 and used for agitating the high-temperature flue gas. When it is necessary to recover and utilize the waste heat generated during the biomass heat and co-production process, the heat-carrying flue gas in the biomass heat and co-production chamber is introduced through the inlet pipe. 5. The gas enters the heat exchange chamber 1. At this time, the heat exchange refrigerant or heat exchange liquid enters the heat exchange component 3 and exchanges heat with the high-temperature flue gas inside the heat exchange chamber 1, thereby heating the heat exchange refrigerant or heat exchange liquid. Finally, the high-temperature flue gas is discharged from the exhaust pipe 6. At the same time, the stirring component 7 stirs the high-temperature flue gas, thereby accelerating the flow of heat from the high-temperature flue gas, thus uniformly heating the heat exchange refrigerant or heat exchange liquid, thereby avoiding uneven heating. At the same time, when the high-temperature flue gas no longer enters the intake pipe 5, the high-temperature flue gas inside the heat exchange chamber 1 can still heat the heat exchange liquid or heat exchange refrigerant. The overall heat exchange efficiency is high, thus making full use of the waste heat generated in the biomass heat and co-production process.

[0025] It should be further explained that the heat exchange assembly 3 includes an inlet pipe 301 fixedly connected to the outer surface of the cover 2, a heat exchange pipe 302 fixedly connected to one end of the inlet pipe 301, and an outlet pipe 303 fixedly connected to one end of the heat exchange pipe 302. One end of the outlet pipe 303 extends to the outside of the cover 2. The heat exchange pipe 302 includes an outer coil 3021 connected to the end of the inlet pipe 301, a connecting pipe 3022 fixedly connected to one end of the outer coil 3021, and an inner coil 3023 fixedly connected to one end of the connecting pipe 3022. One end of the inner coil 3023 is connected to the end of the outlet pipe 303. The heat exchange liquid... Alternatively, the heat exchange refrigerant can enter through pipe 301, then through outer coil 3021, and then through connecting pipe 3022 into inner coil 3023, so that the heat exchange liquid or heat exchange refrigerant can stay inside the heat exchange chamber 1 for a sufficient time. At the same time, high-temperature flue gas enters the heat exchange chamber 1 from the inlet pipe 5 and then exits from the exhaust pipe 6, thus facilitating the heat exchange liquid or heat exchange refrigerant to fully exchange heat with the high-temperature flue gas. Finally, the heat exchange liquid or heat exchange refrigerant is discharged from the outlet pipe 303 for use, thereby facilitating rapid heat exchange and improving the efficiency of heat exchange. The heat exchange refrigerant or heat exchange liquid can be tap water or other liquids.

[0026] It should be explained in detail that the stirring assembly 7 includes a rotating shaft 702 rotatably disposed in the middle of the cover 2, a plurality of stirring blades 703 fixedly connected to the outer surface of the rotating shaft 702, a plurality of through grooves 705 opened on the top of the stirring blades 703, concave arc-shaped sides 704 disposed on both sides of the stirring blades 703, and a stirring motor 701 fixedly connected to one end of the rotating shaft 702 extending to the top of the cover 2; the stirring motor 701 drives the rotating shaft 702 to rotate, thereby causing the stirring blades 703 to rotate. The stirring blades 703 have concave arc-shaped sides 704, which can better stir the high-temperature flue gas and drive the high-temperature flue gas to move up and down, thereby accelerating the flow of the high-temperature flue gas, so as to distribute the heat evenly and thus produce a uniform heating effect.

[0027] The interior of the heat exchange box 1, the inner side of the cover 2, and the outer surface of the heat exchange component 3 are all fixedly provided with an anti-corrosion coating 4 to prevent the flue gas from corroding the interior of the heat exchange box 1 or the heat exchange component 3. At the same time, a filter of the prior art can be installed at the end of the air inlet pipe 5 to intercept dust in the flue gas. Example

[0028] Example 2 further discloses, based on Example 1, that: the inner coil 3023 is located inside the outer coil 3021, and the outer contours of both the inner coil 3023 and the outer coil 3021 are spiral-shaped, so that the heat exchange refrigerant or heat exchange liquid can stay inside the heat exchange box 1 for a sufficient time, thereby facilitating full contact with the high-temperature flue gas and making full use of the heat of the high-temperature flue gas.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
