SPECIFIC EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0017] Embodiment 1, please refer to Figure 1, this embodiment provides an incinerator, which includes an incinerator body 100. A furnace chamber 101 is arranged inside the incinerator body. A feed inlet 102 communicating with the furnace chamber is arranged on the incinerator body. An air inlet chamber 103 communicating with the furnace chamber is arranged below the furnace chamber. A grate 104 is arranged between the air inlet chamber and the furnace chamber. An air inlet 105 communicating with the air inlet chamber is arranged on the incinerator body. A flue gas treatment chamber 106 is also arranged inside the incinerator body. A central pipe 107, a filtering device and a spray pipe 108 are arranged inside the flue gas treatment chamber. The central pipe penetrates through the filtering device and is rotatably connected to the filtering device. A smoke exhaust pipe 109 communicating with the flue gas treatment chamber is arranged at the top of the incinerator body. Both ends of the central pipe are fixedly connected to the incinerator body. One end is closed and the other end communicates with the furnace chamber. A smoke exhaust hole 107-1 communicating with the inside of the filtering device is arranged at the top of the central pipe. The spray pipe is located above the filtering device. One end extends out of the device body and the other end is closed. Nozzles 110 or spray holes are arranged at the bottom of the spray pipe. In this embodiment, the filtering device includes a first fixing plate 111, a second fixing plate 112 and a filter mesh sleeve 113. One end of the filter mesh sleeve is connected to the first fixing plate and the other end is connected to the second fixing plate. The first fixing plate and the second fixing plate are rotatably connected to the central pipe. The filter mesh sleeve is a stainless steel filter mesh sleeve or a plastic filter mesh sleeve.

[0018] When the above incinerator is in use, the spray pipe is used to connect the liquid supply equipment. The feed inlet is used for inputting combustible waste. After the combustible waste enters the furnace chamber and is ignited, the flue gas will enter the filtering device through the central pipe and the smoke exhaust hole, and then move upward through the filter mesh. During the movement, the spray pipe sprays the spray liquid downward through the nozzles or spray holes to treat the flue gas. This incinerator has at least the following advantages: 1. A flue gas treatment chamber and its internal structure are arranged inside the incinerator, so that it has a self-contained flue gas treatment function, and there is no need to cooperate with flue gas treatment equipment, reducing the connection steps and being relatively simple to install; 2. Through the cooperation of the filtering device and the spray pipe, the flue gas enters the filtering device and then is discharged into the flue gas treatment chamber after passing through the filtering device. In this way, when the flue gas passes through the filter mesh, the filter mesh combs the flue gas, effectively preventing the turbulence caused by the temperature difference at different positions during the upward movement of the flue gas from making the contact between a small part of the flue gas and the aerosol insufficient, so that the treatment effect is better; 3. Since the flue gas rises, the particulate matter contained in the flue gas will first accumulate on the top of the filter mesh sleeve. When the particles accumulated on the top of the filter mesh are too many to block the top position of the filter mesh, especially when there is turbulence in the flue gas and a force is generated after encountering the blocked part, it is easy to break the stability of the filtering device and make it rotate, so that the top remains breathable.

[0019] During actual production, a furnace door 134 capable of covering the feed inlet may be provided on the incinerator body. The furnace door can be arranged in an existing manner, such as detachably connecting or rotatably connecting the furnace door to the incinerator body, etc., which is not limited herein.

[0020] 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. The water storage chamber is located above the furnace chamber; a water inlet pipe 119 and a drain pipe are provided on the device body, and the water inlet pipe and the drain pipe are respectively communicated with the water storage chamber; valves 120 are provided on both the water inlet pipe and the drain pipe. This structure replenishes water into the water storage chamber through the water inlet pipe, heats the water in the water storage chamber by using the heat generated by combustion in the furnace chamber, and supplies it for people to use through the drain pipe, so that energy can be better utilized.

[0021] In order to facilitate liquid drainage, a drain pipe 132 communicated with the flue gas treatment chamber is provided at the bottom of the device body, and a drain valve 133 is installed on the drain pipe. The drain valve is just a valve, but it is named the drain valve only for the convenience of distinguishing it from the above-mentioned valve 120.

[0022] In order to prevent the liquid beads in the spray liquid from rising with the flue gas and discharging outside the exhaust pipe, a water baffle 131 is provided above the spray pipe. The water baffle can use an existing structure, which is not specifically limited herein.

[0023] Example 2, please refer to Figure 2 and Figure 3 , the structures of Example 2 and Example 1 are substantially the same, and the differences are as follows: The filter net sleeve includes a plurality of stainless steel filter nets 113-1 and a plurality of elastic filter nets 113-2. The elastic filter nets can be made of rubber or silica gel. The stainless steel filter nets and the elastic filter nets are arranged at intervals. The plurality of stainless steel filter nets are circumferentially arranged with the central pipe as the reference and are located on the same circumference. Thus, it can be seen that the shape of the stainless steel filter net is arc-shaped; A fixing rod 114 is fixed at the bottom of the central pipe, and a runner 115 is rotatably arranged on the fixing rod. One end of the runner away from the central pipe is located on the circumferential reference plane; Among them, the circumferential reference plane refers to the circumferential plane where the inner side surface of the stainless steel filter net is located, referring to the plane where the dotted line is located in the figure; In each of the elastic filter nets, a part is located inside the circumferential reference plane. During production, the two sides of the elastic filter net can be connected to the adjacent stainless steel filter nets, and when connecting, the elastic filter net is made to be straightened. Of course, the shapes of the first fixing plate and the second fixing plate can also be set corresponding to the shape of the filter net cover, referring to Figure 4, which is easy to think of for those skilled in the art; a fan blade 116 is fixed on the stainless steel filter net, and the fan blade is arranged corresponding to the smoke exhaust hole. The fan blade can be arranged on one stainless steel filter net or on multiple stainless steel filter nets. No specific limitation is made here. When this structure is in use, when the flue gas is discharged through the smoke exhaust hole, it pushes the fan blade to drive the filter device to rotate. In the original state, the elastic filter net at the bottom is as shown by the dotted line position in Figure 3 . When the elastic filter net contacts the runner, the runner will gradually lift the elastic filter net, as shown by the solid line position corresponding to the dotted line position in Figure 3 . During the lifting process, the elastic filter net is stretched and the mesh holes become larger, which is convenient for discharging particulate matter and preventing the particulate matter in the flue gas from blocking the filter net sleeve during use.

[0024] As a preferred embodiment, referring to Figure 5 , a reaction bed 117 is arranged between the spray pipe and the filter device. The reaction bed can use existing structures, such as a breathable device filled with packing or a fluidized bed, etc. Its installation is also well-known to those skilled in the art and will not be elaborated 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 net sleeve to form a water film. When the flue gas rises, it first contacts the water film, and harmful substances such as sulfides are absorbed. Then, the flue gas after being filtered by the filter net reaches the reaction bed and contacts the spray liquid for secondary absorption, which greatly improves the treatment effect of the flue gas.

[0025] Embodiment 3. The structure of Embodiment 3 is substantially the same as that of Embodiment 1 or Embodiment 2, except that: the central pipe is fixedly connected to the filter device (specifically fixedly connected to the first fixing plate and the second fixing plate), and both ends of the central pipe are rotatably connected to the incinerator body; in this way, the rotation function of the filter device is realized. A motor can also be installed on the incinerator body, and the motor shaft is connected to the central pipe to drive the central pipe to rotate and further make the filter device rotate.
