Description

TECHNICAL FIELD

[0001] The present application relates to the field of gas purification, in particular to a multifunctional biomass boiler flue gas particulate matter purification device. BACKGROUND

[0002] Biomass boiler is a kind of boiler, biomass boiler is a boiler equipment using biomass energy as fuel, which is environmentally friendly and efficient, and is widely used in industry, commerce and life. Biomass boiler is divided into biomass steam boiler, biomass hot water boiler, biomass hot air furnace, biomass heat conducting oil furnace, vertical biomass boiler and horizontal biomass boiler.

[0003] Biomass boiler produces high-temperature flue gas by burning biomass materials such as straw, rice husk and wood chips, and delivers the high-temperature flue gas to the required heat area through the delivery pipeline to exchange heat and transfer heat to the area that needs heat. The heat energy produced by burning biomass is used for life and production, and the energy generated by biomass materials is reasonably utilized while the biomass materials are treated, saving resources.

[0008] By adopting the technical scheme, the flue gas entering the conveying pipeline is filtered by the filtering mechanism, and the particulate matter is blocked from entering the conveying pipeline, thereby reducing the content of particulate matter in the flue gas in the conveying pipeline, and reducing the probability of damage of the living and production appliances caused by the impact of particulate matter. The vertically arranged filtering part can block the particulate matter in the vertical direction, and the particulate matter needs to overcome its own gravity again to be conveyed again, so it is not easy to be re-entered into the flue gas.

[0010] Optionally, the filter screen comprises a mounting frame, an elastic piece and a screen body, the mounting frame is detachably installed in the filtering part on the machine body, the elastic piece is installed on the mounting frame, and the screen body is installed on the end of the elastic piece away from the mounting frame.

[0011] Optionally, the blocking piece is a receiving hopper, which is detachably installed on the machine body and closes the residue discharge port when installed on the machine body.

[0012] Optionally, a guide ring is installed in the receiving hopper, and the guide ring gradually reduces in diameter from the opening of the receiving hopper to the inner opening of the receiving hopper.

[0013] Optionally, mounting tables are fixedly arranged at both ends of the machine body in the length direction, mounting holes are formed in the mounting tables, and the mounting holes are used to pass through bolts.

[0014] Optionally, the machine body comprises a left half and a right half, the left half and the right half are spliced with each other to form the machine body, the mounting tables comprise a left half table and a right half table, the left half table is fixedly arranged on the left half, and the right half table is fixedly arranged on the right half.

[0015] Optionally, a fixing assembly is arranged between the left half table and the right half table, the fixing assembly comprises a fixing socket and a fixing plug, the fixing socket is formed in the left half table and the right half table, and the fixing socket is an annular hole, two fixing plugs are arranged, and the two fixing plugs are slidably arranged in the left half table and the right half table, respectively, the fixing plug slidably arranged in the left half table is flush with the two sides of the left half table in a normal state, the fixing plug slidably arranged in the right half table is flush with the two sides of the right half table in a normal state, and the fixing plug of the left half table is slidably inserted into the right half table to drive the fixing plug in the right half table to be slidably inserted into the left half table.

[0016] Optionally, a limiting groove is formed in the left half table and the right half table, and a limiting block is fixedly arranged on the fixing plug corresponding to the limiting groove.

[0017] Optionally, the side wall of the fixed plug is deep into the mounting hole, and the bolt is rotated in the mounting hole to drive the fixed plug to slide.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. The filter mechanism filters the flue gas entering the conveying pipeline, blocks the particulate matter from entering the conveying pipeline, thereby reducing the content of particulate matter in the flue gas in the conveying pipeline, thereby reducing the probability of damage to the living and production appliances caused by the impact of particulate matter, and the vertically arranged filter part can block the particulate matter in the vertical direction, and the particulate matter needs to overcome its own gravity again to be conveyed again, thereby being less likely to be reintroduced into the flue gas;

[0020] 2. The flue gas is discharged from the smoke outlet of the boiler into the machine body, and the particulate matter in the flue gas impacts the net body when passing through the net body. The impact force formed by the impact of the particulate matter drives the net body to slide, and the net body reduces the probability of damage caused by the impact by unloading the impact force of the particulate matter. After the particulate matter is blocked and filtered by the net body, the net body is reset under the elastic force of the elastic member. At this time, the particulate matter blocked by the net body is pushed towards the receiving hopper under the action of its own gravity and the elastic force of the net body, and enters the receiving hopper through the guidance of the guide ring. The guide ring can guide the particulate matter into the receiving hopper, and can also reduce the probability of the particulate matter in the receiving hopper being sucked back into the machine body. Subsequently, the particulate matter is discharged by disassembling the receiving hopper, thereby reducing the probability of the particulate matter blocking the connecting channel after the particulate matter accumulates;

[0021] 3. The machine body is divided into two parts, which can facilitate disassembly of the machine body to facilitate maintenance or cleaning of the machine body. At the same time, the division of the machine body can ensure the connection of the boiler and the conveying pipeline when one half of the machine body is cleaned, and the disassembled half of the machine body can be installed without the need for re-alignment with the boiler and the conveying pipeline, thereby facilitating the disassembly and assembly of the machine body;

[0022] 4. The fixed plug of the left half of the machine body slides into the right half of the machine body to drive the fixed plug in the right half of the machine body to slide into the fixed plug hole in the left half of the machine body, so that the fixed plug hole in the right half of the machine body slides into the fixed plug hole left by the fixed plug in the left half of the machine body. The division line between the two fixed plugs is aligned with the division line between the left half and the right half of the machine body by the sliding of the fixed plug, and the left half and the right half of the machine body can be separated. The division line between the two fixed plugs is misaligned with the division line between the left half and the right half of the machine body, and the left half and the right half of the machine body are separated by the fixed plug hole.

[0023] 5. When the limiting block abuts one end of the limiting groove, the two ends of the fixed plug are flush with the connecting surface of the left half or the right half. When the limiting block abuts the other end of the limiting groove, one end of the fixed plug protrudes from the left half or the right half, and the other end is accommodated in the left half or the right half. The arrangement of the limiting block can facilitate the sliding of the partition line between the two fixed plugs to align with the partition line between the left half and the right half, thereby facilitating the disassembly and separation of the left half and the right half, and also reducing the probability of the fixed plug slipping out of the fixed plug hole.

[0024] 6. When the bolt is tightened, the direction of rotation of the bolt is the same as the direction of driving the fixed plug to slide out of the left half or the right half. When the bolt is loosened, the direction of rotation of the bolt is the same as the direction of the fixed plug sliding to flush with the left half or the right half. The rotation of the bolt during tightening or loosening drives the fixed plug to rotate, thereby facilitating the driving of the fixed plug.

[0025] 7. By driving the partition line of the two reinforcing plugs to align with the partition line between the left half and the right half, the reinforcing mechanism loses its reinforcing effect, and at this time the left half and the right half can be disassembled and separated. By driving the partition line of the two reinforcing plugs to be misaligned with the partition line between the left half and the right half, the reinforcing mechanism reinforces the splicing between the left half and the right half, thereby reducing the probability of the left half and the right half being separated.

[0036] With reference to Figure 1 And Figure 4The fixing assembly 7 is arranged between the left half table 51 and the right half table 52, and comprises a fixing socket 71 and a fixing block 72. The fixing socket 71 is arranged in the left half table 51 and the right half table 52, and is a circular hole. Two fixing blocks 72 are arranged in the left half table 51 and the right half table 52, respectively. Since the fixing socket 71 is a circular hole, the fixing block 72 rotates along the central axis of the machine body 1 while sliding. The fixing block 72 in the left half table 51 is flush with the left half table 51 in the normal state, and the fixing block 72 in the right half table 52 is flush with the right half table 52 in the normal state. The fixing block 72 in the left half table 51 is inserted into the right half table 52 to drive the fixing block 72 in the right half table 52 to slide into the left half table 51. One of the fixing blocks 72 is inserted into the fixing socket 71 of the other fixing block 72 to drive the other fixing block 72 to slide into the fixing socket 71 of the first fixing block 72. The sliding of the fixing block 72 aligns the dividing line between the two fixing blocks 72 with the dividing line between the left half body 101 and the right half body 102, and the left half body 101 and the right half body 102 can be separated. The dividing line between the two fixing blocks 72 is misaligned with the dividing line between the left half body 101 and the right half body 102, and the left half body 101 and the right half body 102 are separated by the fixing socket 71. Limiting grooves 8 are arranged in the left half table 51 and the right half table 52, and limiting blocks 9 are arranged on the fixing block 72 corresponding to the limiting grooves 8.

The arrangement of the limiting block 9 facilitates the sliding of the dividing line between the two fixing blocks 72 to align with the dividing line between the left half body 101 and the right half body 102, thereby facilitating the disassembly and separation of the left half body 101 and the right half body 102. The probability of the fixing block 72 sliding out of the fixing socket 71 is also reduced. The side wall of the fixing block 72 protrudes into the mounting hole 6. A bolt is arranged in the mounting hole 6 to drive the fixing block 72 to slide. When the bolt is tightened, the direction of rotation of the bolt is the same as the direction of driving the fixing block 72 to slide out of the left half table 51 or the right half table 52. When the bolt is loosened, the direction of rotation of the bolt is the same as the direction of driving the fixing block 72 to slide to be flush with the left half table 51 or the right half table 52. The rotation of the bolt drives the fixing block 72 to rotate, thereby facilitating the driving of the fixing block 72.

[0037] Referring to Figure 1 and Figure 4The reinforcing mechanism 10 is arranged between the left half body 101 and the right half body 102, and a set of reinforcing mechanisms 10 is arranged on both sides of the slag discharge port 32. The reinforcing mechanism 10 comprises a reinforcing ring groove 1001 and a reinforcing insert block 1002. The reinforcing ring groove 1001 is a circular groove with a T-shaped cross section. The reinforcing ring groove 1001 is arranged on the left half body 101 and the right half body 102. The reinforcing insert block 1002 is a semicircular insert block with a T-shaped cross section. There are two reinforcing insert blocks 1002. The reinforcing insert block 1002 is slidingly arranged in the reinforcing ring groove 1001. When the reinforcing insert block 1002 slides, it rotates along the central axis of the machine body 1. The reinforcing insert block 1002 is uniformly provided with a driving block 11. The driving block 11 provides a gripping point for driving the reinforcing insert block 1002. By aligning the split lines of the two reinforcing insert blocks 1002 with the split line between the left half body 101 and the right half body 102, the reinforcing mechanism 10 loses its reinforcing effect. At this time, the left half body 101 and the right half body 102 can be disassembled and separated. By misaligning the split lines of the two reinforcing insert blocks 1002 with the split line between the left half body 101 and the right half body 102, the reinforcing mechanism 10 reinforces the splicing between the left half body 101 and the right half body 102, thereby reducing the probability of separation between the left half body 101 and the right half body 102.

[0038] The implementation principle of the embodiment of the application is as follows: the filtering mechanism 3 is installed on the left half body 101, then the right half body 102 is abutted against the left half body 101, the filtering mechanism 3 is fixed on the left half body 101 through the slag discharge port 32, the blocking piece 33 is installed on the slag discharge port 32 to close the slag discharge port 32, then the reinforced insertion block 1002 is driven to slide, the separation of the left half body 101 and the right half body 102 is limited, one end of the machine body 1 is bolted to the smoke outlet 01 of the boiler 0, the other end of the machine body 1 is bolted to the conveying pipeline 02, and the installation of the purification device is completed. During the installation process, the rotation of the bolt drives the fixed insertion block 72 in the left half table 51 to slide and insert into the fixed insertion hole 71 in the right half table 52, and the fixed insertion block 72 in the right half table 52 is driven to insert into the fixed insertion hole 71 in the left half table 51. During work, the flue gas generated by the boiler 0 is sent into the machine body 1 through the smoke outlet 01, and the particulate matters in the flue gas impact the net body 313 when the flue gas passes through the net body 313 in the machine body 1. The impact force formed by the impact of the particulate matters drives the net body 313 to slide. After the particulate matters are blocked and filtered by the net body 313, the net body 313 is reset under the elastic force of the elastic piece 312, and the blocked particulate matters are bounced into the receiving hopper 331. When the receiving hopper 331 contains a large amount of particulate matters, the subsequent treatment of the particulate matters is performed by disassembling the receiving hopper 331, and the empty receiving hopper 331 is installed on the slag discharge port 32 to block the slag discharge port 32 and continue the purification of the flue gas. When the machine body 1 needs to be overhauled or cleaned, the bolts between the filtering mechanism 3 and the half machine body 1 to be disassembled are removed through the slag discharge port 32, the bolts connected between the smoke outlet 01 and the conveying pipeline 02 on the half machine body 1 to be disassembled are also removed, the reinforced insertion block 1002 is rotated to align the connecting seams between the reinforced insertion block 1002, the left half body 101 and the right half body 102, and then the half machine body 1 to be disassembled is disassembled for cleaning.
