Description

Technical Field

[0001] This utility model relates to the field of waste incineration technology, specifically to a high-pressure cyclone gas supply device and a municipal solid waste incineration equipment. Background Technology

[0002] Specifically, in existing technologies, waste incinerators typically supply combustion gas through air inlets located on the top or side of the furnace. However, the airflow ejected from the air inlets is difficult to reach all parts of the incinerator, easily causing uneven gas supply. This is especially true for small waste incinerators, where the internal space is small, and uneven gas supply can lead to incomplete combustion, resulting in the production of more harmful gases. The high combustion pressure in the secondary combustion chamber also increases subsequent pollution and leads to high concentrations of exhaust gas pollutants. Existing technologies address these issues by increasing the furnace size, adding air inlets, and increasing the flow rate. However, this approach increases the size of the equipment and makes its structure more complex. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0034] A high-pressure cyclone air supply device, characterized in that, as Figure 1 , Figure 2 As shown, including,

[0035] An annular air inlet pipe 11 is provided at the beginning end of the air inlet pipe 11 and the end of the air inlet pipe 11 is closed.

[0036] Multiple air outlets 13 are connected to the inner annular surface of the air inlet pipe 11 at a certain angle and communicate with the inner cavity of the air inlet pipe 11.

[0037] Specifically, the utility model high-pressure cyclone air supply device 1 has an annular air inlet pipe 11, the starting end of the air inlet pipe 11 is connected to the air inlet 12, and the end is closed. Air enters the air inlet pipe 11 through the air inlet 12. Multiple air outlets 13 are connected to the inner side of the air inlet pipe 11 at a certain angle, and the air outlets 13 are connected to the inner cavity of the air inlet pipe 11.

[0038] After air enters the air intake duct 11 through the air inlet 12, it forms an air jet at the air outlet 13 through the airflow within the air intake duct 11. Since the air outlet 13 is set at a certain angle and is horizontally inclined, the direction of the airflow is conducive to promoting the combustion process and the flow of gas, thus helping to improve the combustion effect.

[0039] In a preferred embodiment, the air outlets 13 are all tilted toward the side of the incoming air that is close to or away from the air inlet duct 11.

[0040] In a preferred embodiment, the axial direction of the air outlet 13 is tangent to the circumference of a target circle located between the air outlets 13.

[0041] Specifically, in this invention, all air outlets 13 are tilted to the same side, and the tilt angle is tangent to the circumference of the target circle between the air outlets 13. This allows the airflow to spontaneously form a cyclone consistent with the target circle after the air outlets 13 eject airflow, thereby accelerating the airflow in the combustion chamber 2 and improving the combustion oxygen supply efficiency.

[0042] In a preferred embodiment, the outer surface of the air outlet 13 is located on the cylindrical surface of the same cylinder.

[0043] Specifically, in this utility model, the fire-resistant wall 3 is cylindrical, and the air outlets 13 are evenly distributed on the surface of the fire-resistant wall 3, which can ensure the uniform distribution of airflow, form a stable cyclone located in the center of the combustion chamber 2, avoid airflow deviation, and improve the combustion effect.

[0044] In a preferred embodiment, the air inlet duct 11 is annular, and the air inlet 12 extends horizontally outward from the starting end of the air inlet duct 11.

[0045] Specifically, the air inlet 12 extends from the starting end of the air inlet pipe 11 along the wall of the fire-resistant wall 3 and connects to the external air supply device.

[0046] A municipal solid waste incineration device, comprising,

[0047] The combustion chamber 2 is surrounded by a fire-resistant wall 3. The fire-resistant wall 3 is equipped with a high-pressure cyclone air supply device 1 as described in any embodiment. The air inlet pipe 11 is distributed along the annular fire-resistant wall 3. The air inlet 12 is connected to the outside, and the air outlet 13 is connected to the combustion chamber 2.

[0048] The ash removal mechanism is located below the combustion chamber 2;

[0049] The exhaust mechanism is connected to the combustion chamber 2 and can controllably discharge the waste gas in the combustion chamber 2.

[0050] Specifically, the air inlet pipe 11 of the high-pressure cyclone air supply device 1 is adapted to the annular fire wall 3. The starting end of the air inlet pipe 11 is connected to the air inlet 12, and the end is closed. Air enters the air inlet pipe 11 through the air inlet 12. Multiple air outlets 13 are connected to the inner side of the air inlet pipe 11 at a certain angle, and the air outlets 13 are connected to the inner cavity of the air inlet pipe 11.

[0051] After air enters the air intake duct 11 through the air inlet 12, it is sprayed at the air outlet 13 through the airflow within the air intake duct 11. Since the air outlet 13 is set at a certain angle and is horizontally inclined, the direction of the airflow is conducive to promoting the combustion process and the flow of gas, thus helping to improve the combustion effect.

[0052] The air outlet 13 of the high-pressure cyclone air supply device 1 is embedded into the fire wall 3 at a unique angle. The fire wall 3 and the high-pressure cyclone air supply device 1 are cast separately.

[0053] In this invention, all air outlets 13 are tilted to the same side, and the tilt angle is tangent to the circumference of the target circle between the air outlets 13. This allows the airflow to spontaneously form a cyclone consistent with the target circle after the air outlets 13 eject airflow, thereby accelerating the airflow in the combustion chamber 2, resulting in better combustion effect in the combustion chamber, reducing exhaust gas emissions, and also allowing for adjustment of the gas supply pressure to ensure sufficient oxygen supply and improve the furnace's processing energy efficiency.

[0054] In a preferred embodiment, a plurality of high-pressure cyclone air supply devices 1 are included, which are evenly distributed in the vertical direction within the fire-resistant wall 3.

[0055] Specifically, this utility model provides multiple high-pressure cyclone gas supply devices 1 that are evenly distributed along the refractory wall 3 of the combustion chamber 2 to form a more efficient high-pressure rising cyclone, which helps maintain efficient combustion in the furnace.

[0056] In a preferred embodiment, the slag discharge mechanism includes,

[0057] A rotating grate 4 is located below the combustion chamber 2 and can controllably discharge the slag produced after combustion.

[0058] The slag hopper 5, used to receive slag, is located below the rotary grate 4.

[0059] Specifically, the rotating grate 4 discharges the slag produced after combustion, preventing the slag from accumulating in the combustion chamber 2 and affecting the combustion effect.

[0060] In a preferred embodiment, the exhaust mechanism includes,

[0061] Cyclone 6 is installed on the fire wall 3 and connected to the combustion chamber 2, which can controllably draw in the waste gas in the combustion chamber 2;

[0062] The cooling device 7, used to cool the exhaust gas, is connected to the cyclone separator 6 and can controllably cool the exhaust gas.

[0063] The blower 8 is used to discharge the cooled exhaust gas and is connected to the cooling device 7.

[0064] Specifically, the cyclone separator 6 provides high negative pressure. After incineration, the cyclone separator 6 is turned on to draw in the waste gas in the incineration chamber 2, the temperature of the waste gas is reduced by the cooling device 7, and the waste is discharged by the blower device 8.

[0065] In a preferred embodiment, a lifting mechanism is also included, disposed on one side of the fire-resistant wall 3, and the lifting mechanism is detachably connected to a trash can 9, such as... Figure 3 As shown, the garbage bin 9 is controllably lifted along the lifting track of the lifting mechanism to be placed upside down above the incineration chamber 2, and the top of the incineration chamber 2 is provided with a movable furnace cover 21.

[0066] Specifically, the removable garbage bin 9 can be lifted to the top of the incineration chamber 2, and the garbage is automatically poured into the incineration chamber 2. The lifting mechanism enables automated garbage disposal, reduces manual operation, and improves efficiency.
