DETAILED DESCRIPTION

[0020] 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.

[0021] For examples, see Figure 1The present embodiment provides an incinerator waste gas treatment and reuse device, comprising a device body 1, wherein the device body can be a waste gas treatment tower body or a sealed container, an air inlet pipe 2 and an exhaust pipe 3 are arranged on the device body, and the air inlet pipe and the exhaust pipe are respectively connected to the inside of the device body. During manufacturing, the air inlet pipe is located below the device body, and the air outlet pipe is located above the device body; a filter screen 4, a reaction bed 5 and a spray device are arranged in sequence from bottom to top at a position between the air inlet pipe and the exhaust pipe inside the device body, wherein the filter screen, the reaction bed and the spray device can use existing structures, such as the reaction bed is a breathable device equipped with fillers or a structure such as a vulcanized bed; an outer sleeve 6 is sleeved on the air inlet pipe, and a sandwich is formed between the outer sleeve and the air inlet pipe, a liquid inlet 6-1 is arranged on the outer portion of the outer sleeve located on the outside of the device body, and a liquid outlet pipe 6-2 is arranged on the outer sleeve near the top, and the liquid outlet pipe extends out of the device body.

[0022] When the above-mentioned incinerator waste gas treatment and recycling device is in use, water or other liquids are introduced into the interlayer, the air inlet pipe is connected to the incinerator, and the incinerator is introduced into the device body. During the introduction process, the waste gas in the air inlet pipe exchanges heat with the water in the interlayer, so that the water temperature in the interlayer increases. The increased water can be discharged through the liquid outlet or introduced into a place where hot water is needed, so that the heat of the waste gas can be reused.

[0023] As a preferred embodiment, the portion of the air intake pipe located inside the device body is provided with a spiral portion 4-1. By providing the air intake pipe with a spiral portion, the corresponding interlayer portion is also spiral. This extends the distance for the exhaust gas to enter the device body relative to the direct discharge of the exhaust gas, allowing the water in the interlayer and the exhaust gas in the collecting pipe to exchange heat more fully.

[0024] As a preferred embodiment, a bypass pipe 6-21 is provided on the portion of the liquid outlet pipe located outside the device body, and the end of the bypass pipe not connected to the liquid outlet pipe passes through the device body and is located between the filter screen and the reaction bed; a first valve 6-22 is provided between the end of the liquid outlet pipe located outside the device body and the bypass pipe, an air inlet 7 is provided on the device body, and the air inlet is located between the filter screen and the reaction bed, and a heating device 8 is provided at a position between the filter screen and the reaction bed in the device body, wherein the heating device is an igniter or electric heater or other device capable of igniting combustible gas, and of course, it can also be a heating wire or other structure, as long as the temperature can achieve the purpose of igniting the incompletely burned combustible gas in the exhaust gas; when this structure is in use, the water temperature in the interlayer increases, causing the water in the interlayer to expand, especially when the first valve is closed, the water in the interlayer expands and evaporates to produce a large amount of water vapor, and the water vapor The gas enters between the filter and the reaction bed through the bypass pipe, causing the gas between the filter and the reaction bed to expand slightly. Part of the water vapor contacts the rising exhaust gas and then enters the reaction bed, cooperating with the water or liquid medicine sprayed downward by the spray device to improve the absorption efficiency of the exhaust gas; at the same time, the air inlet is connected to the air inlet device such as the fan to provide air or oxygen to the part between the filter and the reaction bed, and the heating device ignites the incompletely burned combustible gas (such as carbon monoxide) in the exhaust gas, so that the temperature between the filter and the reaction bed rises, and the gas expands, which is more conducive to the rapid diffusion of water vapor and more uniform contact with the rising exhaust gas. In addition, the gas expansion exerts a certain pressure on the filter, especially when the filter is blocked, the expanded gas impacts the dust on the filter, and cooperates with the falling water or downward moving steam to make the dust easy to fall off the filter; of course, in actual use, after each incineration operation is completed, the filter can also be cleaned by steam expansion. It should be noted that in this embodiment, the liquid inlet is preferably used as the inlet of the liquid, and the liquid outlet pipe is used as the outlet of the liquid. Figure 2 As shown, in this embodiment, a water storage container 14 can be used to connect the liquid inlet, and water is supplied to the interlayer by the pressure of the water storage container. The height of the water storage container can be less than the filter screen and greater than or equal to the height of the liquid outlet pipe. Of course, a water pump can also be used to extract water from the interlayer, which is not specifically limited here.

[0025] As an embodiment, the spray device is a spray pipe 9, on which a plurality of nozzles 9-1 are provided, and a water retainer 10 is provided above the spray pipe. Water or liquid medicine is sprayed to the reaction bed through the nozzles, which is beneficial to purify the soluble waste gas and make the gas discharged through the exhaust pipe cleaner.

[0026] As an implementation mode, a shielding cover 11 for shielding the outlet of the inlet pipe is provided above the inlet pipe in the body of the device, a bracket 12 is fixed above the shielding cover, the bracket is fixed to the inner wall of the body of the device, and a plurality of bearing plates 13 are fixed below the bracket, the bearing plates are respectively connected to the shielding cover and the outer sleeve, so that the bearing plates and the bracket fix the shielding cover and the outer sleeve to the support frame, effectively preventing the outer sleeve and the shielding cover from shaking relative to each other, and preventing the spray liquid from above from entering the inlet pipe. In actual production, the fan can also be installed on the exhaust pipe directly or indirectly by installing a bypass pipe to adjust the exhaust speed of the exhaust gas. When the fan is installed indirectly, a valve can also be installed on the exhaust pipe. This should be known to those skilled in the art and will not be repeated here.
