Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically a waste heat recovery device for calcium oxide digestion. Background Technology

[0002] With global energy supply shortages and rising energy prices, energy conservation and emission reduction have become crucial issues in industrial production. The digestion of calcium oxide (quicklime) releases a significant amount of heat energy, which would be wasted if not recovered. Calcium oxide digestion waste heat recovery devices are designed to recover this heat energy, converting it into usable thermal or electrical energy, thereby improving energy efficiency and reducing production costs.

[0003] Chinese Patent CN219178311U discloses a waste heat recovery and utilization device for calcium oxide production, belonging to the field of calcium oxide production technology. It includes a waste heat recovery cylinder and a heating tank, with a heat conduction device installed between the heating tank and the waste heat recovery cylinder. An exhaust pipe and an inlet pipe are installed at both ends of the waste heat recovery cylinder, respectively. A dust collection box is installed between the waste heat recovery cylinder and the inlet pipe, with a filter screen installed inside. A dust discharge pipe is installed at the bottom of the dust collection box in front of the filter screen. A cleaning mechanism is installed at the bottom of the dust collection box. This device filters the flue gas generated during calcium oxide production through the filter screen inside the dust collection box, and then transfers the heat from the flue gas to the heating tank through the heat conduction device to heat the water, thereby achieving waste heat recovery and utilization. The cleaning mechanism can treat the dust on the filter screen to prevent clogging, which would affect the heat transfer effect and the passage of flue gas, improving the practicality of the device.

[0004] When the above-mentioned calcium oxide digestion waste heat recovery device is in use, after a long period of use, a lot of dust and dirt accumulates in the filter screen during the dust removal operation. As a result, some waste heat is affected by the dust and dirt when it passes through the filter screen, causing the waste heat to be lost, thus resulting in low waste heat recovery efficiency.

[0005] Therefore, this utility model provides a waste heat recovery device for calcium oxide digestion to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a waste heat recovery device for calcium oxide digestion. This device solves the problem that, after prolonged use, dust and dirt accumulate in the filter screen during dust removal operations, causing some waste heat to be lost during filtration and resulting in low waste heat recovery efficiency.

[0008] The cleaning assembly includes a dust collection box with a groove on the inner wall of the dust collection box. A servo motor is fixed to the top of the groove, and a threaded rod is fixed to the output end of the servo motor.

[0014] Beneficial effects

[0015] This invention provides a waste heat recovery device for calcium oxide digestion. Compared with the prior art, it has the following advantages:

[0016] (1) A calcium oxide digestion waste heat recovery device, by setting a cleaning component, enables the filter screen inside the dust collector to be cleaned regularly, thereby preventing the filter screen from being scaled up after long-term use, which would cause heat loss during the dust removal process. This achieves the effect of improving heat recovery while keeping the inside of the dust collector clean. At the same time, the dust collection bag can be installed and removed by the limiting slider, which makes it easier to clean dirt and dust.

[0023] 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.

[0024] Example 1:

[0025] Please see Figure 1-3 A calcium oxide digestion waste heat recovery device includes a device body 1, a cleaning component 2 fixed on the side of the device body 1, and a control component 3 fixed on the top of the device body 1.

[0026] Cleaning component 2 includes a dust collection box 21. A slide groove 22 is provided on the inner wall of the dust collection box 21. A servo motor 23 is fixed at the top of the slide groove 22. A threaded rod 24 is fixed at the output end of the servo motor 23. A slider 25 is threadedly connected to the threaded rod 24. A cleaning brush 26 is fixed on the side of the slider 25.

[0027] A pressure sensor 27 is fixed on the top of the dust collection box 21. The pressure sensor 27 is a KR-3051 type sensor. There are two pressure sensors 27, which are located at both ends of the filter screen. The pressure sensor 27 can control the servo motor 23 to work by measuring the pressure difference before and after the residual heat of the pressure sensor 27.

[0028] The bottom of the dust collection box 21 is fixed with a cleaning port 28, and a lifting groove 29 is provided in the cleaning port 28. A card plate 210 is slidably connected in the lifting groove 29. A handrail 211 is fixed on the side of the card plate 210. Magnetic blocks 212 are fixed on both sides of the top of the card plate 210. When the dust collection bag is replaced, the magnetic blocks 212 can be fixedly adsorbed on the top of the lifting groove 29.

[0029] A trapezoidal plate 213 is fixed inside the cleaning port 28, and a clamping plate 210 is slidably connected to the side of the trapezoidal plate 213. The clamping plate 210 and the trapezoidal plate 213 cooperate with each other to allow the dust collection bag to be installed and fixed.

[0030] In this embodiment, when the dust collector 21 filters and cleans the waste heat for a long time, when the waste heat passes through the filter screen, a pressure difference is formed between the pressure difference before and after the filter screen. This difference is detected by the air pressure sensor 27, which then controls the servo motor 23 to drive the slider 25 to move in the threaded rod 24. This allows the cleaning brush 26 to clean the filter screen periodically. The cleaned dust and dirt fall into the dust collection bag installed in the cleaning port 28. When the dust collection bag is full, the sliding handle 211 can be used to detach the card plate 210 from the trapezoidal plate 213. This allows the card plate 210 to be attracted to the top of the lifting groove 29 by the magnetic block 212 at the top. Then, the dust collection bag can be removed and the dust can be cleaned.

[0031] Example 2:

[0032] Please see Figure 1-4 This embodiment provides a technical solution based on embodiment one. The control component 3 includes a waste heat recovery box 31. The waste heat recovery box 31 has an installation groove 32 inside. A second motor 33 is fixed at the output end of the installation groove 32. A drive gear 34 is fixed at the output end of the second motor 33. A driven gear 35 is meshed with the side of the drive gear 34. A protrusion 36 is fixed on the side of the driven gear 35. A connecting rod 37 is hinged in the protrusion 36. An adjusting block 38 is hinged at the other end of the connecting rod 37.

[0033] The waste heat recovery box 31 is equipped with four sets of regulating blocks 38. The four sets of regulating blocks 38 are symmetrically distributed in the waste heat recovery box 31, and the four sets of regulating blocks 38 can respectively correspond to different devices for heat transfer.

[0034] In this embodiment, according to the heat requirement of the device, the second motor 33 drives the drive gear 34 and the driven gear 35 to mesh and rotate, so that the connecting rod 37 on the side of the driven gear 35 drives the adjusting block 38 to rotate, thereby allowing the adjusting block 38 to control and adjust the amount of heat delivered to the device, so that the waste heat in the waste heat recovery box 31 can be fully utilized, thereby achieving the maximum effect of waste heat secondary utilization.
