DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0027] Example 1, please refer to Figure 1 The present embodiment provides an incinerator, comprising an incinerator body 100, wherein a furnace 101 is provided in the incinerator body, a feed port 102 communicating with the furnace is provided on the incinerator body, an air inlet chamber 103 communicating with the furnace is provided below the furnace, a grate 104 is provided between the air inlet chamber and the furnace, and an air inlet 105 communicating with the air inlet chamber is provided on the incinerator body; a flue gas treatment chamber 106 is further provided in the incinerator body, a central pipe 107, a filter device and a spray pipe 108 are provided in the flue gas treatment chamber, the central pipe passes through the filter device and is rotatably connected to the filter device, and a smoke exhaust pipe 109 communicating with the flue gas treatment chamber is provided on the top of the incinerator body. ; Both ends of the central tube are fixedly connected to the incinerator body, one end is closed, and the other end is connected to the furnace; the top of the central tube is provided with a smoke exhaust hole 107-1 connected to the interior of the filter device; the spray pipe is located above the filter device, one end extends out of the incinerator body, and the other end is closed, and a nozzle 110 or a spray hole is provided at the bottom of the spray pipe; in this embodiment, the filter device includes a first fixed plate 111, a second fixed plate 112 and a filter mesh sleeve 113, one end of the filter mesh sleeve is connected to the first fixed plate, and the other end is connected to the second fixed plate; the first fixed plate and the second fixed plate are rotatably connected to the central tube, wherein the filter mesh sleeve is a stainless steel filter mesh sleeve or a plastic filter mesh sleeve.

[0028] When the above-mentioned incinerator is in use, the spray pipe is used to connect to the liquid supply equipment, and the feed port is used to input combustible waste. After the combustible waste enters the furnace and is ignited, the flue gas will pass through the central pipe and the smoke exhaust hole into the filter device, and then move upward through the filter screen. During this movement, the spray pipe sprays liquid downward through the nozzle or spray hole to treat the flue gas. This incinerator has at least the following advantages:

[0029] 1. The flue gas treatment chamber and its internal structure are set in the incinerator, so that it has its own flue gas treatment function, and no need to use it with flue gas treatment equipment, which reduces the connection steps and is relatively simple to install;

[0030] 2. Through the cooperation of the filter device and the spray pipe, the flue gas enters the filter device and then passes through the filter device to be discharged into the flue gas treatment chamber. In this way, when the flue gas passes through the filter, the filter will comb the flue gas, effectively preventing the turbulence caused by the temperature difference at different positions during the rising process of the flue gas, which will cause a small part of the flue gas to have insufficient contact with the aerosol, thereby achieving better treatment effect;

[0031] 3. Since the flue gas rises, the particulate matter contained in the flue gas will first accumulate on the top of the filter mesh. When the particles accumulated on the top of the filter mesh are too many and block the top of the filter mesh, especially when the flue gas contains turbulent flow and encounters the blocked part, it will generate force, which can easily break the stability of the filter device and make it rotate, so that the top remains breathable.

[0032] In actual production, the incinerator body may also be provided with a furnace door 134 capable of covering the feed port. The furnace door may be provided using existing methods, such as detachably connecting the furnace door to the incinerator body or rotatably connecting the furnace door to the incinerator body, which is not limited here.

[0033] In order to make full use of the heat generated by the combustion furnace, a water storage chamber 118 is also provided in the incinerator body, and the water storage chamber is located above the furnace; a water inlet pipe 119 and a drain pipe are provided on the incinerator body, and the water inlet pipe and the drain pipe are respectively connected to the water storage chamber; valves 120 are provided on the water inlet pipe and the drain pipe. This structure replenishes water in the water storage chamber through the water inlet pipe, uses the heat generated by the combustion in the furnace to heat the water in the water storage chamber, and makes it available to people through the drain pipe, so that energy is better utilized.

[0034] In order to facilitate drainage, a drain pipe 132 connected to the flue gas treatment chamber is provided at the bottom of the incinerator body, and a drain valve 133 is installed on the drain pipe. The drain valve is a valve, which is named as a drain valve just to distinguish it from the above-mentioned valve 120.

[0035] In order to prevent the liquid droplets in the spray liquid from rising with the smoke and being discharged out of the exhaust pipe, a water retainer 131 is provided above the spray pipe. The water retainer can use an existing structure and is not specifically limited here.

[0036] Example 2, please refer to Figure 2 and Figure 3, the structure of embodiment 2 is roughly the same as that of embodiment 1, except that: the filter screen includes multiple stainless steel filter screens 113-1 and multiple elastic filter screens 113-2, the elastic filter screens can be made of rubber or silicone, the stainless steel filter screens and the elastic filter screens are arranged at intervals, and the multiple stainless steel filter screens are arranged circumferentially with the central tube as the reference and are located on the same circumference. It can be seen that the shape of the stainless steel filter screen is arc-shaped; a fixing rod 114 is fixed to the bottom of the central tube, and a rotating wheel 115 is rotatably provided on the fixing rod, and the end of the rotating wheel away from the central tube is located on the circumferential reference plane; wherein the circumferential reference plane refers to the circumferential surface where the inner side surface of the stainless steel filter screen is located, see the plane where the dotted line is located in the figure; a part of each of the elastic filter screens is located on the inner side of the circumferential reference plane, and when making it, the two sides of the elastic filter screen can be connected to the adjacent stainless steel filter screens, so that the elastic filter screen is straightened when connected. Of course, the shapes of the first fixing plate and the second fixing plate can also be set to correspond to the shape of the filter screen cover, see Figure 4 , which is easy for those skilled in the art to think of; the stainless steel filter is fixed with a fan blade 116, which is set corresponding to the smoke exhaust hole, wherein the fan blade can be set on one stainless steel filter, or on multiple stainless steel filter nets, which is not specifically limited here. When the structure is in use, when the smoke is discharged through the smoke exhaust hole, the fan blade is pushed to drive the filter device to rotate. In the original state, the elastic filter net at the bottom is as Figure 3 As shown in the dotted line, when the elastic filter screen contacts the rotor, the rotor will gradually prop up the elastic filter screen. Figure 3 As shown in the solid line position corresponding to the dotted line position, the elastic filter is stretched during the expansion process, and the mesh becomes larger, which facilitates the removal of particulate matter and prevents particulate matter in the flue gas from clogging the filter cover during use.

[0037] As a preferred embodiment, see Figure 5 A reaction bed 117 is provided between the spray pipe and the filter device. The reaction bed can use an existing structure, such as a breathable device equipped with fillers or a sulfurized bed. Its installation is also well known to those skilled in the art and will not be described in detail here. When this structure is in use, the spray liquid first contacts the reaction bed. After saturation, the spray liquid will fall onto the rotating filter sleeve, forming a water film on the filter sleeve. The flue gas first contacts the water film during the rising process, and harmful substances such as sulfides are absorbed. Then, the flue gas accepted by the filter reaches the reaction bed and contacts the spray liquid and is absorbed for the second time, which greatly improves the treatment effect of the flue gas.

[0038] Example 3. The structure of Example 3 is roughly the same as that of Example 1 or Example 2, except that: the central tube is fixedly connected to the filter device (specifically, fixedly connected to the first fixed plate and the second fixed plate), and the two ends of the central tube are rotatably connected to the incinerator body; this realizes the rotation function of the filter device. This structure can also install a motor on the incinerator body, connect the motor shaft to the central tube, drive the central tube to rotate, and then rotate the filter device.
