Description

Technical Field

[0001] The present invention belongs to the technical field of gasifiers, and in particular relates to a slag remover for a gasifier and a method for extracting harmful gases. Background Art

[0002] The gasifier slag remover is a mechanical slag removal device used under the gasifier. The existing gasifier slag remover is a scraper-type slag remover. The scraper chain continuously runs to transport the quenched slag immersed in water to the slag outlet, completing the slag removal process.

[0003] When the existing scraper-type slag collector is in operation, in order to prevent the leakage of harmful gases, the slag collector is simply sealed. However, gas leakage cannot be avoided during slag discharge, and some gas will still overflow from the slag collector, causing pollution; some harmful gases are dissolved in the slag water. When the slag containing slag water is discharged, the harmful gases in the slag water will volatilize, causing pollution to the working environment. The traditional scraper cannot remove the slag, resulting in poor extraction effect of the harmful gases. Summary of the Invention

[0014] Preferably, the vacuum assembly also includes a collecting movable plate and a collecting cylinder. A slag outlet is provided at the top of the bottom surface of the inclined lifting chassis. The collecting box is fixedly installed at the slag outlet. A movable installation slot is provided on the side of the collecting box.

[0015] Preferably, a drive motor is fixedly installed on the outside of the horizontal chassis, and transmission chains are fixedly connected on both sides of the slag scooping mobile filter plate. The drive shaft of the drive motor passes through the horizontal chassis and the sealing partition and is fixedly connected to the drive gear of the transmission chain.

[0016] Preferably, a plurality of filter holes are provided on the movable filter plate for slag removal, and a slag inlet is provided on the top surface of the horizontal machine box.

[0017] A method for extracting harmful gases, using the above-mentioned gasifier slag remover, comprises the following steps:

[0018] When the slag enters the horizontal machine box, it falls onto the horizontal section of the slag moving filter plate, and the slag moving filter plate rotates, and the fixed scraper block and the rotating filter plate drive part of the slag to move. When the fixed scraper block and the rotating filter plate move to the inclined section of the slag moving filter plate, the rotating filter plate rotates, so that the slag moving filter plate, the rotating filter plate, the installed filter plate and the fixed scraper block form an irregular box-shaped container. At this time, the slag moving filter plate stops rotating, and the rotating water squeezing plate rotates and drives the water squeezing block to move closer to the rotating filter plate to squeeze the slag in the irregular box-shaped container.

[0019] After the water squeezing is completed, the vacuum baffle moves into the inclined lifting chassis to seal the inclined lifting chassis and the horizontal chassis, the air inlet and the vacuum port are opened, the air inlet takes in air, and the vacuum port exhausts air, so that all harmful gases in the inclined lifting chassis are extracted. After the vacuuming is completed, the collection box is opened to discharge the slag in the collection box, the collection box is closed, the air inlet and the air outlet are closed, the vacuum baffle is moved out of the slag scooping chassis, the slag scooping movable filter plate rotates, and the slag that has been squeezed out of the water is transferred to the collection box.

[0020] Compared with the prior art, the present invention provides a gasifier slag remover and a method for extracting harmful gases, which has the following beneficial effects:

[0021] 1. When the slag enters the horizontal machine box, it falls on the horizontal section of the slag moving filter plate. The slag moving filter plate rotates, and the fixed scraper block and the rotating filter plate drive part of the slag to move. When the fixed scraper block and the rotating filter plate move to the inclined section of the slag moving filter plate, the rotating filter plate rotates, so that the rotating filter plate, the rotating mounting plate and the fixed scraper block form an irregular box-shaped container. At this time, the slag moving filter plate stops rotating, and the rotating water squeezing plate rotates and drives the water squeezing block to move toward the rotating filter plate to squeeze the slag in the irregular box-shaped container. The irregular box-shaped container can better squeeze the slag. The slag cannot be moved out of the box-shaped container during squeezing, and the slag water in the slag can be fully squeezed out to prevent the harmful gases dissolved in the water from being discharged from the slag machine box together with the slag, causing pollution to the working environment and endangering the health of the workers.

[0022] 2. After squeezing out water, the vacuum baffle moves into the inclined lifting chassis to seal and isolate the inclined lifting chassis from the horizontal chassis. The air inlet pipe and the vacuum pipe are opened, the air inlet pipe takes in air, and the vacuum pipe exhausts air, so that all harmful gases in the inclined lifting chassis are extracted. After vacuuming is completed, the collection box is opened to remove the slag in the collection box. The collection box is closed, the air inlet pipe and the air outlet pipe are closed, and the vacuum baffle is moved out of the slag removal chassis. The slag removal filter plate rotates to transfer the slag that has been squeezed out of the water to the collection box. When discharging slag, the inclined lifting chassis is separated from the horizontal chassis, and the inclined lifting chassis is vacuumed. When the inclined lifting chassis is completely vacuumed, slag is discharged to prevent harmful gas leakage during slag discharge, which reduces the vacuuming effect.

[0023] 3. The limit slider limits the air intake sealing block, and the partition connecting plate drives the movable push plate to move. When the movable exhaust partition moves into the slag scooping chassis to complete the sealing, the movable push plate pushes the limit slider into the limit installation groove. At this time, the limit slider releases the limit of the air intake sealing block. When the air intake sealing block moves upward to open the air inlet, the air intake sealing block limits the movable push plate. When the horizontal chassis and the inclined chassis are not completely separated, the air intake and the air extraction port cannot be opened. When the air intake and the air extraction port are completely closed, the horizontal chassis and the inclined chassis cannot be released from the separation state to prevent harmful gas leakage.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Clearly, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. Based on the embodiments of the application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the application.

[0041] In the description of the application, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner" and the like indicate the orientation or positional relationship, which are only for the convenience of describing the application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the application.

[0042] Embodiments, please refer to Figure 1 Figure 12 The application is a gasification furnace slag conveyor and a method for pumping and discharging harmful gas, which comprises a slag conveyor box 1, a slag conveying assembly 2 and a gas pumping assembly 3. The slag conveyor box 1 comprises a horizontal machine box 102 and an inclined machine box 101.

[0043] The slag conveying assembly 2 comprises a slag conveying moving filter plate 201, a plurality of scraper units 4 and a plurality of water squeezing units 5. The slag conveying moving filter plate 201 is divided into a horizontal section and an inclined section. The scraper units 4 are arranged on the slag conveying moving filter plate 201, and the water squeezing units 5 are arranged in the slag conveyor box 1. The scraper units 4 comprise fixed scraper blocks 401, rotating filter plates 402 and installed filter plates 403. The water squeezing units 5 comprise rotating water squeezing plates 501 and water squeezing blocks 502.

[0044] The slag conveying moving filter plate 201 can drive the fixed scraper blocks 401 to move. The movement of the fixed scraper blocks 401 and the rotating filter plates 402 can drive the slag on the conveyor belt to move. When the rotating filter plates 402 move to the inclined section of the slag conveying moving filter plate 201, the rotating filter plates 402 can rotate. After the rotating filter plates 402 complete rotation, the rotating water squeezing plates 501 can rotate and drive the water squeezing blocks 502 to move towards the rotating filter plates 402.

[0045] The gas pumping assembly 3 comprises an air inlet pipe 301, a gas pumping pipe 302, a moving gas pumping partition plate 303 and a collection box 304.

[0046] After the water squeezing is completed, the moving gas pumping partition plate 303 can move into the slag conveyor box 1. The air inlet pipe 301 can introduce air, the gas pumping pipe 302 can pump out the gas in the slag conveyor box 1, and the collection box 304 can be opened.

[0047] ​When in use, after the slag enters the horizontal machine box 102, it falls onto the horizontal section of the slag moving filter plate 201. The slag moving filter plate 201 rotates, and the fixed scraper 401 and the rotating filter plate 402 drive part of the slag to move. When the fixed scraper 401 and the rotating filter plate 402 move to the inclined section of the slag moving filter plate 201, the rotating filter plate 402 rotates, so that the slag moving filter plate 201, the rotating filter plate 402, the installed filter plate 403 and the fixed scraper 401 form an irregular box-shaped container. When the slag collecting mobile filter plate 201 stops rotating, the rotating water squeezing plate 501 rotates and drives the water squeezing block 502 to move toward the rotating filter plate 402, squeezing water out of the slag in the irregular box-shaped container. The irregular box-shaped container can better squeeze water out of the slag. The slag cannot be moved out of the box-shaped container during squeezing water, and the slag water in the slag can be fully squeezed out, preventing harmful gases dissolved in the water from being discharged from the slag collecting machine box 1 together with the slag, causing pollution to the working environment and endangering the health of the workers.

[0048] After the water is squeezed out, the suction baffle 303 is moved into the inclined lifting case 101, so that the inclined lifting case 101 is sealed and isolated from the horizontal case 102, the air inlet pipe 301 and the suction pipe 302 are opened, the air inlet pipe 301 is taken in, and the suction pipe 302 is exhausted, so that the harmful gases in the inclined lifting case 101 are all extracted. After the exhaust is completed, the collection box 304 is opened to discharge the slag in the collection box 304, the collection box 304 is closed, the air inlet pipe 301 and the air outlet pipe are closed, and the suction baffle 303 is moved out of the slag collecting case 1, and the slag collecting mobile filter plate 201 is rotated to transfer the slag after the water is squeezed out to the collection box 304; when discharging slag, the inclined lifting case 101 is separated from the horizontal case 102, and the inclined lifting case 101 is exhausted. When the exhaust is completed in the inclined lifting case 101, the slag is discharged to prevent the leakage of harmful gases during the slag discharge, which reduces the exhaust effect.
