Description

Technical Field

[0001] The invention relates to the field of environmental protection, and in particular to a smoke treatment device for cracking. Background Art

[0002] Thermal cracking is a process in which the giant molecular chains of solid or liquid organic waste such as waste plastics, waste tires, waste oil, etc. are cut and cracked into low molecular chain oil and gas in an oxygen-deficient environment and at a medium temperature (450-480°C). The oil and gas are then condensed and separated to obtain resource-based materials such as light oil and heavy fuel oil with high added value. Thermal cracking technology is used to treat organic waste and recover useful resources. Thermal cracking reactions will produce a large amount of toxic and harmful gases and some solid particulate dust, which will pollute the environment if discharged directly.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figures 1 to 5As shown, a smoke treatment device for cracking includes a long strip box body 1, an upper partition 2 and a lower partition 3 located below the upper partition 2 are welded inside the box body 1, the upper partition 2 and the lower partition 3 are both horizontally arranged, a driving chamber 4 located above the upper partition 2 and a water collecting chamber 5 located below the lower partition 3 are provided in the box body 1, and a dust removal chamber 6 is provided between the upper partition 2 and the lower partition 3.

[0029] like Figure 2 As shown, a plurality of vertically arranged guide plates 7 are welded in the dust removal chamber 6 and are evenly spaced left and right along the length direction of the box body 1. The guide plates 7 divide the dust removal chamber 6 into a plurality of spray chambers 8, and each spray chamber 8 is provided with a spray mechanism.

[0030] The guide plate 7 includes a plurality of lower baffles 9 and a plurality of upper baffles 10, and the lower baffles 9 and the upper baffles 10 are arranged alternately. The lower baffles 9 are sealedly connected to the front and rear side walls of the box body 1 and the lower partition 3, and the upper baffles 10 are sealedly connected to the front and rear side walls of the box body 1 and the upper partition 2. Flow openings 11 for smoke to pass through are respectively provided between the upper end of the lower baffle 9 and the upper partition 2 and between the lower end of the upper baffle 10 and the lower partition 3. An air inlet pipe 37 connected to the leftmost spray chamber 8 is fixedly installed at the left end of the box body 1, and an air outlet pipe 38 connected to the rightmost spray chamber 8 is fixedly installed at the right end.

[0031] After the flue gas enters the dust removal chamber 6 through the air inlet pipe 37, it flows through multiple spray chambers 8 from left to right in sequence and is discharged through the air outlet pipe 38. Since multiple guide plates 7 are provided, the flue gas is diverted through the flow opening 11 at the upper end of the lower baffle 9 and the flow opening 11 at the lower end of the upper baffle 10 between the spray chambers 8, thereby extending the time the flue gas stays in the dust removal chamber 6 and improving the effect of spraying and dust removal on the flue gas.

[0032] The guide plate 7 is also movably mounted with an adjustment plate 12 for adjusting the opening of the corresponding flow opening 11. Specifically, one side of the adjustment plate 12 is welded with two front and rear slideways 13 arranged opposite to each other, the slideway 13 extends vertically, and the adjustment plate 12 is slidably mounted between the front and rear slideways 13. During specific use, the adjustment plate 12 can be adjusted according to the requirements for smoke dust treatment: the adjustment plate 12 is slid along the slide 13 to increase the area of ​​one end of the adjustment plate 12 extending into the corresponding flow port 11, thereby reducing the cross-section of the flow port 11 through which smoke can pass, and reducing the opening of the flow port 11, which slows down the passage of smoke through the flow port 11, further prolongs the residence time of smoke in the dust removal chamber 6, and is more conducive to improving the effect of smoke spray dust removal; conversely, the adjustment plate 12 is slid along the slide 13 to reduce the area of ​​one end of the adjustment plate 12 extending into the corresponding flow port 11, thereby increasing the cross-section of the flow port 11 through which smoke can pass, and increasing the opening of the flow port 11, which speeds up the passage of smoke through the flow port 11, so as to improve the dust removal efficiency of smoke.

[0033] The adjusting plate 12 includes a first adjusting plate 14 vertically slidably mounted on one side of the lower baffle 9 and a second adjusting plate 15 vertically slidably mounted on one side of the upper baffle 10; an adjusting mechanism for driving the adjusting plate 12 to move up and down is provided in the driving chamber 4, and the adjusting mechanism includes a vertically extending adjusting rod 16 fixedly mounted on the adjusting plate 12 by bolts, and the upper end of the adjusting rod 16 passes upward through the upper partition 2 and extends into the driving chamber 4, and the upper ends of several adjusting rods 16 corresponding to the first adjusting plate 12 are fixedly mounted on the first movable plate 17 by bolts, and the upper ends of several adjusting rods 16 corresponding to the second adjusting plate 15 are fixedly mounted on the second movable plate 18 by bolts, and the second movable plate 18 is located below the first movable plate 17, and the second movable plate 18 is provided with an avoidance hole for the adjusting rod 16 on the first movable plate 17 to pass through.

[0034] A vertically extending slide bar 19 is fixedly installed in the driving chamber 4 by bolts. Two slide bars 19 are arranged opposite to each other on the left and right. The first movable plate 17 and the second movable plate 18 are both slidably installed on the two slide bars 19 to improve the stability of the first movable plate 17 and the second movable plate 18 sliding up and down. The first movable plate 17 and the second movable plate 18 are driven by a power mechanism to move closer to or away from each other. The power mechanism includes an adjustment motor 20 installed on the top of the box body 1 by bolts. The output end of the adjustment motor 20 is provided with a positive and negative threaded rod 21 extending downward into the driving chamber 4. The positive and negative threaded rod 21 is arranged parallel to the slide bar 19. The lower end of the positive and negative threaded rod 21 is rotatably connected to the upper partition 2 through a bearing. The outer side of the positive and negative threaded rod 21 is symmetrically provided with two sections of external threads with opposite rotation directions. The first movable plate 17 and the second movable plate 18 are respectively screwed on the external threads of the positive and negative threaded rod 21 with different rotation directions.

[0035] Specifically, the forward and reverse screw rods 21 are driven to rotate forward by the adjusting motor 20 so that the first movable plate 17 and the second movable plate 18 are brought closer to each other, and the first movable plate 17 drives the first adjusting plate 12 to descend through the corresponding adjusting rod 16, and at the same time, the second movable plate 18 drives the second adjusting plate 15 to rise through the corresponding adjusting rod 16, thereby increasing the opening of the flow port 11 and improving the dust removal efficiency of the flue gas; conversely, the forward and reverse screw rods 21 are driven to rotate reversely by the adjusting motor 20 so that the first movable plate 17 and the second movable plate 18 are moved away from each other, and the first movable plate 17 drives the first adjusting plate 12 to rise through the corresponding adjusting rod 16, and at the same time, the second movable plate 18 drives the second adjusting plate 15 to descend through the corresponding adjusting rod 16, thereby reducing the opening of the flow port 11 and improving the effect of spraying and dust removal on the flue gas.

[0036] There are multiple water holes evenly distributed on the lower partition 3, and a drainage mechanism connected to the water collecting chamber 5 is provided at the bottom of the box body 1. The water mist sprayed by the spray mechanism can enter the water collecting chamber 5 through the water holes on the lower partition 3 and be discharged from the drainage mechanism for subsequent treatment.

[0037] Separation plates 22 corresponding to the guide plates 7 are welded in the water collecting chamber 5. The separation plates 22 are located directly below the corresponding guide plates 7. The separation plates 22 divide the water collecting chamber 5 into a plurality of water collecting chambers 23. The separation plates 22 can prevent smoke from flowing horizontally in the water collecting chamber 5. The drainage mechanism row specifically includes a main drainage pipe 24 extending horizontally below the box body 1. A drainage branch pipe 25 is connected between the main drainage pipe 24 and the bottom of each water collecting chamber 23.

Specifically, the front end of the spray pipe 26 is closed, and the rear end of the spray pipe 26 extends to the outside of the box body 1 and is connected to a hose 28 through a rotary joint, and the hose 28 is connected to the main water supply pipe 36. Clean water or cleaning liquid enters the spray pipe 26 through the hose 28, and is sprayed from the plurality of nozzles 27 at the bottom of the spray pipe 26 into the spray chamber 8, so as to spray and remove dust contained in the flue gas.

[0039] The spray pipes 26 are rotatably connected to the front and rear side walls of the box body 1 through bearings. The rear ends of the two spray pipes 26 of the same spray mechanism are fixedly installed with synchronous gears 29 located on the outside of the box body 1. The two synchronous gears 29 are meshed with each other, so that the two spray pipes 26 can rotate toward or away from each other.

[0040] A driving box 30 is fixedly installed on the front side of the box body 1 by bolts, and the front end of one of the spray pipes 26 of the spray mechanism extends into the driving box 30 and is fixedly installed with a driving gear 31. A laterally extending guide rod 32 is fixedly installed in the driving box 30 by bolts, and a rack 33 meshing with the driving gears 31 of multiple spray mechanisms is slidably installed on the guide rod 32. The rack 33 is driven by the driving mechanism to reciprocate left and right. The driving mechanism includes a driving motor 34 installed in the driving box 30 by bolts, and a reciprocating screw 35 arranged parallel to the guide rod 32 is provided at the output end of the driving motor 34.

[0041] The reciprocating screw 35 is driven to rotate by the driving motor 34, and the reciprocating screw 35 drives the rack 33 to move back and forth along the guide rod 32. The rack 33 acts on the driving gear 31 and drives one of the spray pipes 26 of the spray mechanism to rotate back and forth, so that the two spray pipes 26 rotate alternately toward and away from each other to expand the coverage of the water mist sprayed by the spray pipe 26, reduce the spray blind angle, and further improve the effect of spraying and dust removal on the flue gas.
