A flue gas inlet 110 is arranged at the bottom of the air-cooled heat exchanger 120, and the other end of the flue gas exhaust pipe 130 is connected to the flue gas treatment component 200.

[0041] It should be noted that the smoke inlet 110 arranged at the bottom of the air-cooled heat exchanger 120 is used to connect a pipeline, the other end of which is connected to the cremator, thereby guiding the smoke exhausted by the cremator to the air-cooled heat exchanger 120. The high-temperature smoke is cooled by the vertical air-cooled heat exchanger 120 and then discharged from the top into the smoke exhaust pipe 130. It can be understood that the air-cooled heat exchanger 120 is composed of multiple cooling fans, and the cooling fans and related accessories can be obtained from the market, and their structure and function realization principle will not be elaborated here.

[0042] Optionally, a flue gas treatment component 200 is connected to the air cooling component 100 through a flue gas exhaust pipe 130, and the flue gas treatment component 200 is mainly used to effectively treat harmful substances and particulate dust in the flue gas, wherein the flue gas treatment component 200 includes a support frame 210, a spark interceptor 220, a bag dust collector 230 and an activated carbon adsorber 240 which are sequentially arranged on the top of the support frame 210, the smoke inlet end of the spark interceptor 220 is connected to the smoke outlet end of the air cooling component 100 through a pipeline, the smoke outlet end of the spark interceptor 220 is connected to the bag dust collector 230 through a bag filter smoke inlet pipe 222, and the smoke inlet end of the activated carbon adsorber 240 is connected to the smoke outlet end of the bag dust collector 230 through a pipeline;

It can be understood that the Mars interceptor 220, the bag-type dust collector 230 and the activated carbon adsorber 240 can be obtained from the market, and their structures and functional implementation principles will not be elaborated here.

[0044] It should be noted that, in the conventional exhaust gas treatment equipment of the cremator, the spark interceptor 220, the bag-type dust collector 230 and the activated carbon adsorber 240 are independently arranged and connected in sequence through pipes. In the present embodiment, it can be understood that the spark interceptor 220, the bag-type dust collector 230 and the activated carbon adsorber 240 are actually integrated and installed inside the steel shell at the top of the support frame 210, and the pipes between the spark interceptor 220, the bag-type dust collector 230 and the activated carbon adsorber 240 are then arranged. The spark interceptor 220 can process the sparks in the flue gas, and the bag-type dust collector 230 can further purify the flue gas through the microfiltration effect of the bag to achieve the purpose of flue gas purification. The activated carbon adsorber 240 can further remove the smoke particles through the fine pores of the activated carbon in the activated carbon drawer 21, and adsorb and microfilter the toxic and harmful substances such as dioxins in the flue gas to achieve the purpose of flue gas purification.

[0045] In some embodiments, a bracket is provided at the interval of the steel shell on the side end face of the flue gas treatment component 200, and a gas tank 250 is fixedly installed on the bracket. The gas tank 250 is connected to the Mars interceptor 220 and the bag dust collector 230 through multiple arrays of pipes to provide air pressure. A pulse control valve 251 and an adapter 252 are provided between each of the pipes. The setting of the adapter 252 facilitates the installation and connection of the gas tank 250, and the pulse control valve 251 facilitates the control of the opening and closing of the gas tank 250.

[0047] Optionally, the bottom of the Mars interceptor 220 is configured to be conical or conical, and a first cleaning valve 221 is provided at its bottom end. The first cleaning valve 221 is connected to a pipe and is used to remove particulate dust intercepted by the Mars interceptor 220. Of course, in order to facilitate the inspection and maintenance of the Mars interceptor 220, a cabinet door is provided on the end face close to the first cleaning valve 221, and a sealing cover is provided at the corresponding top of the Mars interceptor 220. In order to further process the flue gas treated by the Mars interceptor 220, its bottom is connected to the bag filter smoke inlet pipe 222, and the other end of the bag filter smoke inlet pipe 222 is sealed and connected to the bag dust collector 230.

A Rhodes blower 234 is connected to the other end of the cleaning pipe 233. The Rhodes blower 234 is configured to provide suction. The smoke dust particles attached to the outer wall of the bag in the bag-type dust collector 230 fall off and fall into the bottom of the bag-type dust collector 230 under the action of gravity, and are finally removed through the cleaning pipe 233 to achieve the purpose of exhaust gas purification.

[0049] Optionally, the flue gas treated by the bag filter 230 flows into the activated carbon adsorber 240, and a plurality of activated carbon drawers 241 are arranged at intervals in an array on the side end surface of the activated carbon adsorber 240. Activated carbon is placed in the plurality of stacked activated carbon drawers 241. After the bag filter 230 removes large particles of dust, the flue gas enters the activated carbon adsorber 240, and the smoke particles are further removed through the fine pores of the activated carbon in the activated carbon drawer 241, and toxic and harmful substances such as dioxins in the flue gas are adsorbed and micro-filtered, thereby achieving the purpose of flue gas purification.

[0050] In some embodiments, Figure 4 As shown, one side end of the activated carbon adsorber 240 is sealed and connected to the exhaust gas emission component 300, and the exhaust gas emission component 300 includes an induced draft fan 320, an exhaust gas exhaust pipe 310 and a chimney 330 respectively connected to both ends of the induced draft fan 320, and one end of the exhaust gas exhaust pipe 310 away from the induced draft fan 320 is sealed and connected to the bag filter 230. The induced draft fan 320 is provided to provide power to the flue gas so that the filtered and purified flue gas can be discharged in time.

The integrated setting of the equipment for adsorption and filtration makes the installation simpler and saves manpower, reduces the use of pipelines, and saves space after the equipment is installed.

[0052] At the same time, through the arrangement of the spark interceptor 220, the bag dust collector 230 and the activated carbon adsorber 240, the smoke exhausted by the cremator can be filtered and adsorbed in turn to remove harmful substances and dust. By connecting the vertical air-cooled heat exchanger 120 through a pipe at one end of the spark interceptor 220, the vertical air-cooled heat exchanger 120 occupies a smaller space and can effectively cool the high-temperature smoke exhausted by the cremator.

[0053] In addition, by setting a support frame 210 at the bottom of the flue gas treatment component 200, the setting of the support frame 210 is convenient for installation and fixation. At the same time, space is reserved at the bottom of the Spark interceptor 220, the bag-type dust collector 230 and the activated carbon adsorber 240, which is convenient for the arrangement of the cleaning equipment and pipelines of the Spark interceptor 220 and the bag-type dust collector 230.
