[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0026] Refer to Figures 1 - 5 , a waste heat boiler soot control device, including a furnace body 1, a steam chamber 2 is fixed on the top of the furnace body 1 by bolts, a smoke inlet pipe 3 is connected and fixed on one side of the furnace body 1, a filter plate 8 is fixed on one side of the smoke inlet pipe 3 by bolts, the filter plate 8 filters the particles in the flue gas, slide rods 11 are fixed on the inner walls of both sides of the smoke inlet pipe 3 by bolts, a brush plate 10 is slidably connected between the two slide rods 11, and the brush plate 10 is in contact with the filter plate 8. A threaded rod 9 is rotatably connected to the top of the smoke inlet pipe 3, and the threaded rod 9 is threadedly connected to the brush plate 10. An avoidance port 7 is opened at the bottom of the smoke inlet pipe 3, and two L-shaped limiting plates 19 are fixed on the outer wall of the bottom of the smoke inlet pipe 3 by bolts, and the L-shaped limiting plates 19 are located on both sides of the avoidance port 7. A slide plate 17 is slidably connected inside the L-shaped limiting plate 19, and a collection box 18 communicated with the avoidance port 7 is fixed between the two slide plates 17. Rotate the threaded rod 9 to drive the brush plate 10 to move along the slide rod 11, so that the brush plate 10 scrapes the impurities on the filter plate 8, and the scraped impurities fall through the avoidance port 7 into the collection box 18 for collection. A plurality of heat conduction plates 4 are installed on the inner wall of the bottom of the furnace body 1, and a plurality of heat conduction rods 5 are installed on the inner wall of the bottom of the furnace body 1, and the tops of the heat conduction rods 5 and the heat conduction plates 4 both pass through the steam chamber 2. A plurality of heat conduction blocks 6 are installed on the outer side of the heat conduction rod 5, and the heat conduction blocks 6 on two adjacent heat conduction rods 5 are staggered with each other. The filtered flue gas enters the furnace body 1 through the smoke inlet pipe 3. At this time, the heat conduction plates 4, the heat conduction rods 5 and the heat conduction blocks 6 absorb the heat in the flue gas and conduct it into the steam chamber 2.

[0027] In the present utility model, it should be noted that on both inner walls of the smoke inlet pipe 3, communication pipes 14 are installed. On one side of the communication pipe 14, a spray head 15 is fixedly connected in a communicating manner. On the outer walls of multiple sides of the smoke inlet pipe 3, water pipe brackets 13 are installed. The two ends of the water pipe bracket 13 respectively pass through the smoke inlet pipe 3 and are connected to the communication pipe 14 in a communicating manner. Water in the water pipe bracket 13 enters the spray head 15 through the communication pipe 14 and is sprayed out, so that the mist conducts dust reduction treatment on the flue gas. The top end of the threaded rod 9 passes through the smoke inlet pipe 3 and is welded with a knob 12, which is convenient for the staff to rotate the threaded rod 9. Between the two L-shaped limit plates 19, a baffle 16 is fixed by bolts, and the baffle 16 is fixed to the bottom outer wall of the smoke inlet pipe 3. The baffle 16 can limit the position of the collection box 18 to prevent the collection box 18 from moving excessively and affecting the use of the device. On one outer wall of the collection box 18, a pull handle 20 is fixed by bolts. Pulling the pull handle 20 backward enables the collection box 18 to slide outward along the L-shaped limit plate 19 through the sliding plate 17, thus facilitating the staff to separate the collection box 18 from the smoke inlet pipe 3 and further facilitating the treatment of impurities in the collection box 18.

[0028] Working principle: External flue gas enters the interior of the furnace body 1 through the smoke inlet pipe 3. At this time, the filter plate 8 filters the particles in the flue gas. Then, the heat conducting plate 4, the heat conducting rod 5 and the heat conducting block 6 absorb the heat in the flue gas and conduct it into the steam chamber 2. When it is necessary to clean the particles on the filter plate 8, rotate the knob 12, and the threaded rod 9 rotates to make the brush plate 10 move along the sliding rod 11. Thus, the brush plate 10 scrapes the impurities on the filter plate 8. The scraped impurities fall through the avoidance port 7 into the collection box 18 for collection.

[0029] In addition, the terms "installation", "setting", "connection", and "socket connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components or parts. Those of ordinary skill in the art can understand the specific meanings of the above terms in this application according to specific circumstances.
