Description

[0002] The waste heat drying bed technology for low-temperature flue gas purification of large boilers is an efficient and environmentally friendly technology that can effectively treat low-temperature flue gas emitted by industrial boilers and recover moisture and pollutants in the flue gas. The main principle of this technology is to dry and purify the flue gas at a lower temperature through a heat exchange process. Specifically, when the low-temperature flue gas passes through the drying bed, it comes into contact with the desiccant, and the moisture in the flue gas is adsorbed or reacted by the desiccant, thereby achieving a drying effect.

The fine particles in the soot will block the microporous structure of the desiccant, reducing its adsorption capacity and thus affecting the drying effect. The accumulation of soot may make it difficult for the desiccant to restore its original adsorption performance during the regeneration process, resulting in a decrease in regeneration efficiency.

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figure 1-2 and Figure 6-7 As shown, the utility model proposes a large boiler low-temperature flue gas purification waste heat drying bed, including a drying box 1, and also includes two groups of drying devices installed in the drying box 1. The two groups of drying devices can work independently. The drying device includes a plurality of dehumidification plates 403, and a desiccant is arranged in the dehumidification plate 403. The desiccant absorbs the moisture in the flue gas. A gap is arranged between two adjacent dehumidification plates 403. The drying device includes an air intake mechanism and an air return mechanism. The air intake mechanism blows hot air into the gap between the plurality of dehumidification plates 403. When the desiccant is saturated, the desiccant can be heated by blowing hot air into the gap between the dehumidification plates 403, so that the moisture in the desiccant is discharged. The air return mechanism absorbs the moisture in the gap between the plurality of dehumidification plates 403. The air return mechanism can regenerate the desiccant by absorbing the moisture, so that the desiccant can adsorb the moisture again.

[0034] The drying device includes a drying cylinder 4 fixedly installed in the drying box 1, wherein a cavity 401 is provided in the drying cylinder 4, and a pipe groove 402 is fixedly installed in the cavity 401, and the pipe groove 402 is used to install an air intake mechanism and an air return mechanism. A dehumidification plate 403 is fixedly installed in the cavity 401 and fixedly connected to the pipe groove 402.

The hot air is connected to the first fan 407 (the generation of hot air is a prior art and will not be described in detail here), and the hot air is transported to the inside of the air intake pipe 404 through the first fan 407, and the first valve 406 is in an open state at this time. The hot air entering the air inlet pipe 404 will enter the drying cylinder 4 through the first air inlet hole 410 and the second air inlet hole 411 and be located between the two dehumidification plates 403, thereby heating the desiccant in the dehumidification plates 403, causing the moisture in the desiccant to evaporate into water vapor and escape from the desiccant.

[0036] Among them, the air return mechanism includes an air return pipe 405 fixedly installed in the pipe groove 402, the air return pipe 405 passes through the bottom of the drying box 1 and extends to the outside of the drying box 1, a second valve 408 is installed on the air return pipe 405, a second fan 409 is fixedly installed on the second valve 408, a plurality of first air return holes 413 are provided on the air return pipe 405, a plurality of second air return holes 414 are provided on the pipe groove 402, the first air return holes 413 and the second air return holes 414 correspond to each other one by one and are in a coaxial position, the first air return hole 413 is located between two adjacent dehumidification plates 403, and an air return joint 415 is fixedly installed between the first air return hole 413 and the second air return hole 414. The second fan 409 generates suction in the return air pipe 405. At this time, the second valve 408 is in an open state. The first return air hole 413 and the second return air hole 414 generate suction on the gas between two adjacent dehumidification plates 403, thereby sucking out the water vapor between the two dehumidification plates 403, thereby completing the drying of the desiccant and making the desiccant reusable.

[0037] When the smoke is dried, closing the first valve 406 and the second valve 408 can prevent the smoke from entering the air inlet pipe 404 and the air return pipe 405 , and the moisture in the smoke is absorbed by the multiple dehumidification plates 403 .

[0038] like Figure 3-5 and Figure 8As shown, two dust removal devices are installed on one side of the drying box 1. The two dust removal devices can work independently. The dust removal device includes a vibration dust removal component. The vibration dust removal component separates the smoke on the dust removal device from the dust removal device.

The gas entering the dust removal box 2 will enter the filter bag 701 through the connecting hole 702, and the dust in the gas will be absorbed by the filter bag 701, so that the dust in the gas will remain on the filter bag 701, and the gas can move outward through the filter bag 701, thereby completing the filtration of the gas.

[0039] The driving mechanism includes a first motor 706 fixedly mounted on the vibration plate 704, a linkage belt 705 rotatably mounted on the vibration plate 704, a plurality of pulleys on the linkage belt 705 corresponding to and fixedly connected to the plurality of filter bags 701, and an output shaft of the first motor 706 fixedly connected to one of the pulleys. The linkage belt 705 can be driven to rotate by the first motor 706, thereby causing the plurality of filter bags 701 to rotate synchronously, so that the smoke can be evenly contacted with the filter bags 701, thereby improving the utilization rate of the filter bags, and improving the filtering effect and efficiency.

[0040] The vibration dust removal assembly includes two sets of support seats fixedly installed in the dust removal box 2, a gap is provided between the two sets of support seats, a mounting plate 8 is fixedly installed between the two sets of support seats, the mounting plate 8 is fixedly connected to the support seats, the support seat includes a base plate 805 fixedly installed in the dust removal box 2, a slide plate 801 slidably installed in the dust removal box 2, a spring 802 is fixedly installed between the base plate 805 and the slide plate 801, the mounting plate 8 is fixedly connected to the slide plate 801, a second motor 803 is fixedly installed on the mounting plate 8, and an eccentric wheel 804 is fixedly installed on the output shaft of the second motor 803. An ash hopper 9 is fixedly installed in the dust removal box 2. The second motor 803 is driven to drive the eccentric wheel 804 to rotate, thereby causing the second motor 803 to vibrate and transmit the vibration to the mounting plate 8, which can enable the mounting plate 8 to drive the slide plate to vibrate. The first motor 706 is fixedly connected to the mounting plate 8, which can drive the vibration plate 704 to vibrate, and the vibration plate 704 will drive the filter bag 701 to vibrate, so that the dust absorbed on the filter bag 701 can be separated from the filter bag 701 and the dust can fall into the ash hopper 9.

[0041] like Figure 1-3As shown, the dust removal box 2 is provided with an air inlet 201 and an air outlet 202, and two groups of conveying holes 5 and output holes 503 are provided in the drying box 1. The two groups of conveying holes 5 correspond to and are connected with the two drying cylinders 4 one by one, and the two groups of air outlets 202 correspond to and are connected with the two drying cylinders 4 one by one. A conveying nozzle 204 is commonly provided on the two air inlets 201, and an output nozzle 203 is commonly provided on the two air outlets 202. The air inlet 201 and the air outlet 202 on the same dust removal box 2 are both rotatably installed with valve cores 6, a transmission rod 601 is fixedly connected between the two valve cores 6, a valve motor 602 is fixedly installed on the dust removal box 2, the output shaft of the valve motor 602 is fixedly connected to one of the valve cores 6, an input pipe 3 is fixedly installed on the output nozzle 203, a first connection box 501 is fixedly installed on a group of delivery holes 5, a first connection box 501 is fixedly installed on two first connection boxes 501, an air inlet valve 504 is provided at the connection between the first connection box 501 and the second connection box 502, and the input pipe 3 is connected to the second connection box 502. First, the low-temperature flue gas to be treated is transported to the inside of the dust removal box 2 through the delivery nozzle 204, and the opening and closing state of the valve core 6 is controlled by the valve motor 602, so as to control whether the low-temperature flue gas can enter the dust removal box 2. Thus, the two dust removal devices can work at the same time, or one of the dust removal devices can work. When the dust on the filter bag 701 needs to be cleaned, the valve motor 602 controls the valve core 6 to be closed, and the dust on the filter bag 701 can be cleaned at this time, while the other dust removal device works normally at this time, so that the low-temperature flue gas can be continuously dusted, which can effectively improve the treatment effect of the low-temperature flue gas. By controlling the opening and closing state of the air intake valve 504, it is possible to control whether the gas can enter the drying cylinder 4, so that the two drying devices can work at the same time and one of the drying devices can be started. When the desiccant needs to be dried, the air intake valve 504 connected to the drying device is closed, and the desiccant can be dried through the air intake mechanism and the air return mechanism. At the same time, the other drying device can work normally, so that the low-temperature flue gas can be continuously treated. The treated low-temperature flue gas will be discharged through the output hole 503.

[0042] Working principle: First, the low-temperature flue gas to be treated is transported to the inside of the dust removal box 2 through the delivery nozzle 204, and the opening and closing state of the valve core 6 is controlled to control whether the low-temperature flue gas can enter the dust removal box 2. The dust in the low-temperature flue gas is adsorbed by the dust removal device. When the dust on the filter bag 701 needs to be cleaned, the valve core 6 is controlled to be closed by the valve motor 602, and the second motor 803 is driven to drive the filter bag 701 to vibrate, so that the dust absorbed on the filter bag 701 can be separated from the filter bag 701 and the dust falls into the ash hopper 9. At this time, the other dust removal device works normally and can continuously remove dust from the low-temperature flue gas. The gas passing through the dust removal box 2 enters the drying box 1 through the input pipe 3. Whether the gas can enter the drying cylinder 4 can be controlled by controlling the opening and closing state of the air intake valve 504. When the desiccant needs to be dried, the air intake valve 504 connected to the drying device is closed, and the desiccant can be dried through the air intake mechanism and the air return mechanism. At the same time, the other drying device can work normally, so that the low-temperature flue gas can be continuously processed. The processed low-temperature flue gas will be discharged through the output hole 503.
