Description

Technical Field

[0001] The present invention relates to the technical field of grate combustion-assisting ignition, and particularly to an ignition and combustion-assisting device for a garbage pyrolysis grate and a using method thereof. Background Technique

[0002] The ignition and combustion-assisting device for a garbage pyrolysis grate is a core component to ensure the safe and efficient start of the garbage pyrolysis process. It supplies fuel to the burner through a fuel supply system. The burner sprays and ignites the fuel to generate a high-temperature flame, quickly heating the garbage to the temperature required for pyrolysis, thereby maintaining stable operation. Through an emission treatment system, it reduces environmental impacts, ensuring that the entire pyrolysis treatment process is both effective and environmentally friendly.

[0003] The traditional garbage pyrolysis grate ignites fuel through a burner to provide a high-temperature flame, and the pretreated garbage is put into the grate. The high temperature causes the garbage to quickly pyrolyze to generate combustible gas and residue; during this process, the temperature inside the furnace is controlled by adjusting the fuel supply and air flow to ensure the stable progress of the pyrolysis reaction; the generated combustible gas can be further burned to recover energy, and the residue is subjected to subsequent treatment; however, it is difficult to assist combustion inside the grate during the incineration process, resulting in the inability to quickly increase the temperature inside the furnace, prolonging the pyrolysis startup time and affecting the overall treatment efficiency. Insufficient combustion assistance will cause the garbage not to be completely pyrolyzed, generating a large amount of unburned combustible gas and soot, increasing the difficulty and cost of subsequent treatment. At the same time, the unburned combustible gas and soot contain harmful substances, increasing the difficulty of emission treatment and thus polluting the environment. Summary of the Invention

At the same time, it solves the problem that the unburned combustible gas and soot in the traditional device contain harmful substances, increasing the difficulty of emission treatment and thus polluting the environment.

[0026] 2.

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, 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 efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figure 1 and Figure 2 , an ignition and combustion assisting device for a waste thermal cracking grate, an incinerator body 1, a main grate 5 is arranged on one side of the incinerator body 1, and one side of the top of the incinerator body 1 is connected with a feed hopper 6. Slots are opened on both sides inside the feed hopper 6, and feed rollers 7 are installed inside the slots.

[0042] Please refer to Figure 2 、 Figure 3 and Figure 4, a combustion-supporting mechanism 2 is located at the top of the grate body 5 and is used to support combustion inside the grate body 5. The combustion-supporting mechanism 2 includes a fuel supply seat 21 fixed on the top of the incinerator body 1 and an oxygen pump 22 installed on the top of the fuel supply seat 21. A fuel supply pipe 23 and a connecting pipe 24 are connected to the same side of the fuel supply seat 21 and the oxygen pump 22 respectively. The fuel supply pipe 23 is communicated with the connecting pipe 24. The connecting pipe 24 extends to the interior of the grate body 5 and is installed with a sealing box 25. A fuel supply port 28 is connected to the bottom of the sealing box 25. A rotating component for driving the fuel supply port 28 to rotate is arranged between the fuel supply port 28 and the grate body 5. Two connecting soft plates 211 are connected between the sealing box 25 and the fuel supply port 28, and interference strips 29 are fixed on both sides of the bottom of the sealing box 25. The fuel supply port 28 and the interference strips 29 are mutually connected. Correspondingly, the rotating assembly includes two rotating seats 213 fixed on the top of the combustion port 28, the two rotating seats 213 are hinged to the bottom of the sealing box 25, and the two sides of the two rotating seats 213 are respectively connected with a rotating shaft 212 and a transmission shaft, the rotating shaft 212 and the transmission shaft respectively extend to the two sides of the grate body 5 and are fixed with baffles and a rotating disk 27, a limiting assembly for limiting the rotating disk 27 is arranged between the rotating disk 27 and the grate body 5, the limiting assembly includes a fixing groove opened on the top of the grate body 5 and a limiting block 210 installed inside the fixing groove, a plurality of limiting holes for inserting the limiting block 210 are opened on one side of the rotating disk 27, a control groove is opened on the top of the limiting block 210, and protrusions are fixed on both sides of the limiting block 210, and protrusions for sliding the protrusions are opened on both sides of the fixing groove;

[0043] When garbage enters the grate body 5, the combustion supply seat 21 and the oxygen pump 22 cooperate with each other, so that the combustion port 28 sprays flames into the grate body 5, thereby achieving a combustion-supporting effect, and the control groove drives the limit block 210 to move in the fixed groove, and the movement of the limit block 210 drives the convex block to move in the convex groove, so that the limit block 210 is separated from the limit hole.

It avoids the situation that insufficient combustion-supporting will lead to incomplete thermal cracking of garbage, a large amount of incompletely burned combustible gas and smoke, and increased difficulty and cost of subsequent processing. At the same time, it solves the problem that incompletely burned combustible gas and smoke in traditional devices contain harmful substances, increase the difficulty of emission treatment, and then cause pollution to the environment.

[0044] Further, as Figure 4 shown, a rotary knob 26 is fixed on one side of the rotary disk 27, and a plurality of uniformly distributed friction blocks are fixed on the outer wall of the rotary knob 26. Based on this, through the arrangement of the plurality of friction blocks, it is more convenient for the staff to rotate the rotary knob 26, and the phenomenon of slipping is avoided.

[0045] Please refer to Figure 5 , Figure and Figure 7 , a wind supply mechanism 3 for supplying air to the fuel supply port 28 is provided on the top of the grate body 5. The wind supply mechanism 3 includes an air delivery pump 33 fixed on the top of the grate body 5.

The baffle 31 is connected with one of the rotary seats 213. A jet head 36 corresponding to the fuel supply port 28 is fixed on one side of the delivery pipe 35. A rotation groove for the linkage pipe 32 to rotate is opened on one side inside the grate body 5, and a cavity for the baffle 31 to insert is opened inside the rotation groove;

[0046] The air delivery pump 33 uses the intake pipe 34 to transport air into the delivery pipe 35, and the delivery pipe 35 transports the air into the linkage pipe 32, and then sprays it out through the jet head 36, so that the fuel supply port 28 can be assisted by wind during combustion, further improving the combustion assistance efficiency. When the fuel supply port 28 rotates, it drives the baffle 31 to rotate synchronously. Through the arrangement of the cavity, the baffle 31 can protect the linkage pipe 32 during the rotation process, avoiding damage to the linkage pipe 32. Through the clamping of the wind, it helps to reduce the residue of unburned garbage, thereby improving the overall combustion efficiency, and can more accurately control the problem inside the grate body 5, helping to prevent the grate body 5 from being blocked and keeping it unobstructed.

[0051] S2. When the garbage enters the grate body 5, the combustion seat 21 and the oxygen pump 22 cooperate with each other to make the combustion port 28 spray flames, thereby achieving combustion-supporting in the grate body 5 and improving the incineration efficiency of the garbage;

[0053] S4, by setting the air delivery pump 33, the air is delivered to the air delivery pipe 35 by the air inlet pipe 34, and the air is blown to the bottom of the fuel supply port 28 by the nozzle 36, so that the fuel supply port 28 is more efficient in assisting combustion;

[0054] S5, when the fuel supply port 28 drives the blocking plate 31 to rotate synchronously during the rotation process, the linkage pipe 32 can be blocked from the fuel supply port 28 by the rotation of the blocking plate 31, so as to prevent the combustion-supporting flame from damaging the linkage pipe 32;

[0055] S6. The electric push rod 42 drives the moving plate 43 to move up and down. The movement of the moving plate 43 drives the multiple top rods 44 to move synchronously. The movement of the multiple top rods 44 drives the top plate 45 to move. The movement of the top plate 45 causes it to come into contact with the garbage. The contact with the garbage allows the garbage to burn more fully.
