Description

Technical Field

[0001] This utility model relates to the field of tar collection technology, and more specifically to a flue gas tar collection device. Background Technology

[0002] Biomass materials, as a primary source for preparing hard carbon materials, are widely used in the hard carbon production industry. Biomass includes all plants, microorganisms, animals, and their waste products. Biomass materials are an important component of renewable energy, and their efficient development and utilization play a positive role in solving energy and ecological problems. Many plant-based wastes are used in the preparation of hard carbon materials, such as coconut shells, walnut shells, and peanut shells.

[0003] In the rapid pyrolysis of biomass, the biomass feedstock is rapidly heated to a high reaction temperature under oxygen-deficient conditions, triggering the decomposition of macromolecules and producing small-molecule gases, condensable volatiles, and a small amount of coke products. The condensable volatiles are rapidly cooled into a flowable liquid called bio-oil or tar. Bio-oil is dark brown or dark black and has a pungent, burnt odor. During the high-temperature carbonization of biomass, the large amount of tar contained in the flue gas can easily clog the furnace body and pipes, severely affecting equipment lifespan, production efficiency, and production rhythm. Therefore, it is necessary to modify the carbonization equipment to mitigate tar clogging and extend its service life. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] See Figure 1 .

[0027] This utility model relates to a flue gas tar collection device, comprising:

[0028] Collection box 1 has a flue gas inlet 101 and a flue gas outlet 102 for flue gas to enter and exit;

[0029] The receiving plate 2 is set inside the collection box 1, dividing the collection box 1 into two independent spaces, upper and lower, for receiving the liquefied tar that is released during the movement of flue gas.

[0030] The partition 3 is disposed in the upper independent space formed by the collection box 1 and the receiving plate 2, in order to extend the movement path of the flue gas in the collection box 1.

[0031] The present invention provides a flue gas tar collection device. By using a receiving plate 2 and a partition plate 3 together, after the flue gas enters the collection box 1, the partition plate 3 extends the path within the collection box 1, allowing the flue gas to gradually cool down during movement. The tar it carries liquefies and precipitates out of the flue gas, falling onto the receiving plate 2, thereby achieving the collection and treatment of the tar carried in the flue gas.

[0032] In one embodiment, see Figure 1 , 2 The bottom of the collection box 1 is provided with a tar outlet 103. The receiving plate 2 is slidably connected to the collection box 1, and the liquefied tar on the receiving plate 2 can be scraped off and fall into the tar outlet 103 as the receiving plate 2 moves. This design allows for automatic tar treatment by moving the receiving plate 2, and the structure is simple and the operation is convenient.

[0033] In one embodiment, see Figure 2The tar outlet 103 is equipped with a valve. This design enables the structure of this application to achieve simultaneous production and tar discharge, improving production efficiency. Specifically, by closing the valve, the sliding receiving plate 2 connects the upper and lower independent spaces. At this time, the tar on the receiving plate 2, the tar in the new flue gas, and some flue gas fall into the lower independent space. Then, the upper and lower independent spaces of the sliding receiving plate 2 are separated, and the valve can be opened to clean the tar.

[0034] In one embodiment, see Figure 2 The collection box 1 has a clearance groove 104 for the receiving plate 2 to pass through. At both ends of the clearance groove 104, there are tracks 4 that slide in conjunction with the receiving plate 2. This design ensures the stability of the receiving plate 2's sliding motion through the tracks 4.

[0035] In one embodiment, see Figure 3 The receiving plate 2 can slide out of the track 4 and the clearance groove 104. This design makes the receiving plate 2 detachable, which facilitates maintenance and replacement of the receiving plate 2 after a large amount of impurities in the flue gas have accumulated on it.

[0036] Specifically, the track 4 has a through groove for the receiving plate to slide, and the open end of the through groove is connected to the relief groove 104.

[0037] In one embodiment, see Figure 2 , 3 Each of the two tracks 4 has a scraper 5 attached to its upper and lower sides, and the scraper 5 is in contact with the surface of the receiving plate 2. This design allows the scraper 5 to scrape away the tar adhering to the upper and lower surfaces of the receiving plate 2 as it slides.

[0038] In one embodiment, see Figure 3 The cross-section of the scraper 5 is a right-angled triangle, and the connecting edge of the corresponding right-angled side and the hypotenuse of the scraper 5 is in contact with the receiving plate 2. With this design, the scraped tar can fall more effectively under the action of the hypotenuse of the scraper 5.

[0039] In one embodiment, see Figure 1 The partition 3 divides the upper independent space into two interconnected spaces, with the flue gas inlet 101 and the flue gas outlet 102 located in the two spaces respectively. This design extends the path of the flue gas within the collection box 1.

[0040] In one embodiment, see Figure 1The partition 3 is vertically arranged, and its top and side portions are connected to the collection box 1, respectively. The flue gas inlet 101 and the flue gas outlet 102 are located on both sides of the inner top of the collection box 1. This design maximizes the path of the flue gas within the collection box 1.

[0041] In one embodiment, see Figure 1 The distance between the partition 3 and the receiving plate 2 is equal to the distance between the partition 3 and the side wall of the collection box 1. This design prevents sudden changes in flue gas pressure and velocity caused by drastic changes in the cross-sectional area of ​​the flue gas flow.

[0042] It should also be noted that the receiving plate 2, partition plate 3, and inner wall of collection box 1 in this application can be made of different materials, such as polytetrafluoroethylene, PP, stainless steel, etc., depending on the specific application conditions.

[0043] It should be noted that if the embodiments of this utility model involve directional indicators such as up, down, left, right, front, back, etc., the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicators will also change accordingly.
