Description

Technical Field

[0001] The invention relates to the technical field of gasifiers, and in particular to an energy-saving gasifier with a filtering function. Background Art

[0002] The equipment that heats the liquid gas in the vaporizer until it is vaporized. Simply put, the cold liquid gas becomes gaseous gas after passing through the "induction vaporizer". The heating can be indirect or direct. The energy-saving liquefied gasifier makes the liquefied gas molecular bonds fully vaporized and saturated before burning, so as to achieve the effect of increasing the calorific value, increasing the firepower intensity, and saving energy and protecting the environment.

[0003] The gasified fuel gas contains impurities such as dust and tar. These dust particles may come from the raw materials themselves, friction during the production process or intrusion from the external environment. If the dust particles are not filtered, they may cause wear and blockage to subsequent combustion equipment, so they need to be purified by filters. The filter element is the core component of the fuel gas filter, and its main function is to isolate and capture impurities and particulate matter in the fuel gas. Since tar begins to condense and precipitate in small amounts below 300°C, the condensed tar easily blocks the filter material, so the filter element needs to be cleaned or replaced regularly. Once cleaned and replaced, the gas pipe connection needs to be completely dismantled and removed before being assembled. The operation is relatively large, time-consuming and labor-intensive, and the efficiency is relatively low. Moreover, the current filtration relies solely on the filter element without pre-filtering the impurities, resulting in a relatively high cleaning rate for filter element replacement.

The connection structure is simple and stable.

[0039] See also Figure 4 , Figure 5 , Figure 7 and Fig. 9 A servo motor 62 is fixedly installed at the bottom center of one end of the fixed frame 30 by bolts, and a movable screw 60 is connected to the output end of the servo motor 62. A fourth bevel gear 63 is fixedly installed at the top of the movable screw 60 by bolts, and one side of the fourth bevel gear 63 is meshed with a third bevel gear 64. A support shaft 65 is fixedly installed at the top center of the third bevel gear 64 by bolts. The top of the support shaft 65 extends through the filter cartridge 20, and the top of the support shaft 65 is fixedly installed with a second bevel gear 46 that is movably meshed with the first bevel gear 43 by bolts. The rotational meshing of multiple sets of bevel gears drives the cleaning plate 41 to clean the filter screen plate 40 through the rotation of the movable screw 60, and the cleaning structure is simple and stable.

[0040] See also Figure 6 and Figure 8 A connecting plate 66 is fixedly installed at one end of the fourth bevel gear 63 in the fixed frame 30 by bolts, and the top of the movable screw 60 passes through the bearing on the connecting plate 66, and L-shaped movable rods 67 are fixedly installed at both ends of the movable block 61 by bolts, and the top of the L-shaped movable rod 67 is fixedly installed on the two ends of the support plate 31 by bolts, and the penetrating connection is realized to realize the synchronous connection of the movement of the movable block 61.

[0041] A T-shaped slot 37 is provided at the top center of the limiting base 33, and a T-shaped slider 38 is slidably connected to the limiting base 33 in the T-shaped slot 37. The top end of the T-shaped slider 38 is fixedly mounted on the two ends of the support plate 31 by bolts, so that the support plate 31 can move back and forth stably and smoothly. The bottom end of the rotating shaft 35 is connected to a T-shaped fixing column 70 movable in the V-shaped fixing slot 36 through a rotating plate 39 to achieve a flipping effect.

[0042] See also Figure 4 , Figure 5 and Figure 7 A rotating handle 52 is fixed at both ends of one side of the filter element bottom plate 51 by bolts, and the filter element bottom plate 51 and the filter ring 50 are movable in the filter cartridge 20. Filter holes 47 are evenly opened on the filter mesh plate 40. The other side of the filter element bottom plate 51 is threadedly connected with a filter element body 53 to filter the exhausted gas.

[0043] The bottom end of the dust collecting tube 44 is threadedly connected to a dust collecting cylinder 45. The filter cylinder 20 and the fixing frame 30 are both sealed structures. A movable groove 23 that matches the size of the rotating shaft 35 is opened between the filter cylinder 20 and the fixing frame 30, and the rotating shaft 35 moves in the movable groove 23, passing through the connection, driving the filter ring 50 to flip.

[0044] Working principle: Low-temperature liquid is injected into the furnace body through the liquid inlet pipe 14 at the bottom of the gasification furnace body 10, and then high-temperature steam is injected through the heating pipe 13. The low-temperature liquid is heated in the gasification furnace body 10 to turn into gaseous gas and then discharged from the fuel gas pipe and the filter cartridge 20;

[0045] When entering the filter cartridge 20, the large particles of impurities in the gas are first filtered through the filter holes 47 in the filter screen 40. The filter screen 40 blocks the impurities and allows them to enter the arc surface on the top of the fixing frame 30, and then slides down into the dust collecting pipe 44. Finally, the gas is concentrated into the dust collecting cartridge 45 through the dust collecting pipe 44. The gas after filtering the larger impurities enters the filter ring 50. The fine impurities and tar in the gas are blocked by the filter element body 53 on the filter ring 50. The filter element is made of ceramic material. The gas filtered by the filter cartridge 20 is connected to the external pipeline.

[0046] After a certain period of use, when the pressure gauge 19 rises to a certain value, it indicates that the filter element is clogged, and the servo motor 62 in the fixed frame 30 drives the movable screw 60 to rotate, and the movable screw 60 drives the third bevel gear 64 and the support shaft 65 to rotate through the fourth bevel gear 63. The top of the support shaft 65 engages with the first bevel gear 43 through the second bevel gear 46 to rotate. During the rotation of the first bevel gear 43, the cleaning plate 41 and the cleaning brush are driven by the cleaning shaft 42 to brush and clean one side of the filter screen plate 40, and the impurities blocked in the filter hole 47 are brushed down, and then discharged through the dust collecting barrel 45 under the dust collecting pipe 44, and finally the dust collecting barrel 45 is rotated and removed to discharge the impurities, which is simple to operate.

[0047] During the rotation, the movable screw 60 drives the support plate 31 on the limit base 33 to move through the movable block 61 and the L-shaped movable rod 67. The support plate 31 runs stably and smoothly in the T-shaped slot 37 and the T-shaped slide block 38 on the limit base 33. During the movement, the support plate 31 drives the rotating shaft 35, the rotating plate 39 and the T-shaped fixed column on the rotating disk 34 to move synchronously. When the T-shaped fixed column moves in the V-shaped fixed groove 36, the rotating shaft 35 connected to the rotating plate 39 will be driven to flip, so that the filter ring 50 connected to the top of the rotating shaft 35 will flip in the filter cartridge 20. When the filter ring 50 moves to one end of the filter cartridge 20, the filter element 53 is located on the inner side of the filter cartridge 20. At this time, the operator can rotate the filter element bottom plate 51 from the filter ring 50 to remove it through the rotating handle 52 on the filter element bottom plate 51, so as to clean or replace the filter element 53.

[0048] After cleaning or replacement is completed, the servo motor 62 reverses to drive the filter ring 50 to reset and use, and at the same time, the cleaning plate 41 is reversed through the transmission connection of multiple sets of bevel gears to achieve the cleaning effect of the filter plate 40 again, and the cleaning is thorough.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
