Description

Technical Field

[0001] This utility model relates to the technical field of rock wool production equipment, and in particular to a waste heat recovery device for rock wool production. Background Technology

[0002] Rock wool board is a widely used thermal insulation and decorative material in the construction industry. Through a high-temperature melting process, basalt is transformed into fine inorganic fibers, which are then shaped into boards using a special process. This material has advantages such as low density, low thermal conductivity, and good fire resistance, and has become the preferred material for exterior wall insulation, roof insulation, and other projects, especially suitable for public buildings with high fire protection requirements.

[0003] Chinese Patent CN213515119U discloses an energy-saving, emission-reducing, and environmentally friendly incineration heat exchange device for rock wool production, including a furnace body. A waste heat recovery box is fixedly installed on one side of the furnace body. Through the arrangement of the waste heat recovery box and a water tank, waste gas is discharged into the inner cavity of the heat exchange tube through a waste gas exhaust pipe. The hot gas in the heat exchange tube heats the air inside the waste heat recovery box. Then, the waste gas inside the heat exchange tube enters a filter box and is discharged into the water body inside the water tank through a U-shaped pipe, thus utilizing the residual heat in the waste gas to heat the water. A blower draws external air into the inner cavity of the air inlet pipe, where it undergoes initial heating by the hot water inside the water tank. The heated air then enters the inner cavity of the waste heat recovery box through a connecting pipe. The air in the waste heat recovery box absorbs the heat carried by the waste gas inside the heat exchange tube for secondary heating. The heated air is then sent back into the inner cavity of the furnace body by the blower, thus achieving the purpose of waste heat recovery.

[0004] However, the above technical solution has the following shortcomings: the exhaust outlet of the device is directly inserted into the water body inside the water tank, which not only results in low heat exchange efficiency, but also poses a risk of liquid backflow when the exhaust gas stops being discharged. Furthermore, some substances in the exhaust gas will form mud-like substances after encountering water, which will block the exhaust outlet and greatly affect the normal discharge of exhaust gas. Utility Model Content

[0005] The purpose of this invention is to provide a waste heat recovery device for the production of rock wool that not only improves the treatment effect of waste gas, but also avoids water backflow and blockage at the exhaust port.

[0006] This utility model is achieved through the following technical solution: a waste heat recovery device for producing rock wool, comprising a base and a purification device; a heat exchange box and a water tank are provided on the base, a heat exchange tube is provided on the heat exchange box, and a purification box is provided on the water tank; the purification device includes a fixed frame provided inside the purification box, a jet seat provided on the fixed frame, multiple nozzles provided on the jet seat, a first spray seat and a second spray seat provided inside the purification box, multiple spray heads distributed in a ring array on the first spray seat and the second spray seat, a pump body provided on the water tank, and a conduit for connecting the pump body with the first spray seat and the second spray seat; one end of the heat exchange tube is connected to the jet seat, a channel is coaxially provided on the first spray seat, and the second spray seat is located directly above the channel.

[0007] To better realize this utility model, the top of the purification box is provided with a detachable top cover, and a filter plate is provided inside the purification box.

[0008] To better realize this utility model, the purification box is further provided with a positioning frame inside, and the filter plate is set on the positioning frame.

[0009] To better realize this utility model, a cleaning pipe is further provided on the purification box.

[0010] To better realize this utility model, one end of the heat exchange tube is connected to an exhaust pipe, and a rotary connector is provided between the heat exchange tube and the exhaust pipe.

[0011] To better realize this utility model, the heat exchange box is further provided with a drive assembly, which includes a mounting bracket on the heat exchange box, a motor on the mounting bracket, a first gear connected to the motor drive, and a second gear coaxially mounted on the heat exchange tube; the first gear and the second gear are meshed together.

[0012] To better realize this utility model, the heat exchange tube is further provided with multiple connecting rods, the connecting rods are provided with rotating frames, the rotating frames are provided with fixing plates, and the fixing plates are provided with multiple through holes.

[0013] To better realize this utility model, the heat exchange box is further provided with a water inlet pipe and a water outlet pipe.

[0014] Compared with the prior art, this utility model has the following advantages and beneficial effects: (1) In this utility model, the exhaust gas is sprayed downward from the nozzle of the jet seat and diffuses upward. The pump body transports the treatment liquid in the water tank to the first and second spray seats through the conduit. The treatment liquid is sprayed downward from the nozzle and flows downward to form a gas-liquid countercurrent contact, which greatly increases the gas-liquid contact area and can fully adsorb the dust and harmful components in the exhaust gas. At the same time, the purified exhaust gas needs to be filtered twice by the filter plate to further remove residual impurities, and the purification effect is significantly improved. (2) The downward-facing nozzle design of this utility model can prevent the treatment liquid from flowing into the nozzle due to gravity, thus eliminating the backflow of water from the source; and the contact between the waste gas and the treatment liquid is completed in the spray space, rather than the outlet being inserted into the water, which avoids the accumulation of mud-like substances in the nozzle or outlet and completely solves the clogging problem; the detachable top cover of the purification box, together with the positioning frame, allows the filter plate to be quickly removed for cleaning or replacement; the cleaning pipe can directly discharge the waste liquid and a small amount of sediment at the bottom of the purification box without disassembling the device, reducing maintenance costs and improving the ease of use of the equipment; (3) In this utility model, the motor drives the first gear to rotate, and the gear meshing drives the second gear and the heat exchange tube to rotate. When the heat exchange tube rotates, the connecting rod drives the rotating frame and the fixed plate to rotate synchronously. The rotation of the fixed plate can actively accelerate the water flow in the heat exchange box, break the limitation of "natural heat exchange of static water", and improve the heat exchange efficiency. The through holes on the fixed plate can reduce the water flow resistance, so that the water in the heat exchange box forms a spiral flow, avoid the situation of local water overheating and local water not being heat exchanged, ensure that the water temperature in the entire heat exchange box is uniform, and maximize the utilization of the waste heat in the exhaust gas. The water inlet pipe and the water outlet pipe can replace the water in the heat exchange box at any time, realize the continuous recovery and utilization of waste heat, and improve the energy saving effect. (4) All components of this utility model are directly matched in structure and function, with no redundancy or contradiction in design. The device is highly stable during operation and has a low failure rate. The heated water can be flexibly used in various production and living scenarios, and the waste heat utilization rate is high. The emissions after waste gas purification meet environmental protection standards and can meet the environmental protection requirements of different regions. It is suitable for various rock wool production workshops. All components are conventional components in the existing industrial field. There is no need to customize special parts. The manufacturing cost is the same as that of the existing device, but the function and efficiency are significantly improved. It has a high cost performance and is suitable for widespread application. Attached Figure Description

[0020] Example 1: like Figures 1-4 As shown in the figure, the waste heat recovery device for producing rock wool proposed in this embodiment includes a base 1 and a purification device; a heat exchange box 2 and a water tank 12 are provided on the base 1, a heat exchange tube 3 is provided on the heat exchange box 2, and a purification box 4 is provided on the water tank 12.

[0021] The purification device includes a fixed frame 5 installed inside the purification chamber 4, a jet seat 6 installed on the fixed frame 5, multiple nozzles 7 installed on the jet seat 6, a first spray seat 8 and a second spray seat 10 installed inside the purification chamber 4, multiple spray heads 11 arranged in a ring array on the first spray seat 8 and the second spray seat 10, a pump body 13 installed on the water tank 12, and a conduit 14 for connecting the pump body 13 with the first spray seat 8 and the second spray seat 10; one end of the heat exchange tube 3 is connected to the jet seat 6, a channel 9 is coaxially provided on the first spray seat 8, and the second spray seat 10 is located directly above the channel 9.

[0022] In this embodiment, the heat exchange pipe 3 that transports the flue gas passes through the heat exchange box 2 and then enters the jet seat 6.

[0024] In this embodiment, the exhaust gas after the treatment liquid reaction undergoes secondary purification through filter plate 17 to further ensure the quality of the treatment. The detachable top cover 15 and positioning frame 16 facilitate cleaning and replacement of the filter plate 17, improving the ease of use of the device. The cleaning pipe 18 is used to absorb the waste liquid at the bottom of the treatment purification tank 4. A door can also be installed on the side wall of the purification tank 4 to allow for periodic disinfection and cleaning of the interior of the purification tank 4. Other parts of this embodiment are the same as those in the previous embodiment and will not be described again.

[0025] Example 3: like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment proposes a waste heat recovery device for producing rock wool.

A fixing plate 21 is provided on the rotating frame 20. Multiple through holes 22 are provided on the fixing plate 21.

[0026] The heat exchange box 2 is equipped with a water inlet pipe 29 and a drain pipe 30.

[0027] In this embodiment, the exhaust pipe 27 is used to connect the furnace body to transport the waste heat generated during the production of rock wool.

At the same time, the motor 24 is started to drive the first gear 25 to rotate. The first gear 25 and the second gear 26 mesh and drive each other. With the assistance of the rotating connector 28, the heat exchange tube 3 rotates around its own axis. At the same time, the rotating frame 20 on it is driven to rotate through the connecting rod 19 to accelerate the flow rate of the water in the heat exchange box 2, thereby improving the heat exchange efficiency between the heat exchange tube 3 and the water. The fixed plate 21 with through hole 22 design further accelerates the heat exchange efficiency. The heated water can be used to heat the air entering the furnace body or for other water use events, realizing the function of heat recovery and utilization.

[0028] It should be noted that the heat exchange box 2 has reserved space inside for an air inlet pipe connecting to the furnace body, allowing the air entering the furnace body to pass through the heated heat exchange box 2 first, and then be preheated by exchanging heat with the hot water. The other parts of this embodiment are the same as those in the above embodiment and will not be repeated here.
