Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0027] like Figure 1-5As shown, a secondary oven waste gas filtering and collecting device comprises a box body 1, an air inlet 2 and an exhaust port 3 are respectively arranged at two ends of the box body 1, and a filter assembly 4 is arranged inside the box body 1.

[0028] Specifically, the filter assembly 4 includes a first filter part 101 for cooling and flushing the exhaust gas with water, a second filter part 102 for absorbing moisture in the exhaust gas, and a third filter part 103 for adsorbing harmful substances in the exhaust gas, and the first filter part 101, the second filter part 102, and the third filter part 103 are arranged in sequence along the exhaust gas discharge direction.

[0029] By connecting with the oven through the air inlet 2, the exhaust gas discharged from the oven enters into the box body 1 from the air inlet 2. First, the exhaust gas will pass through the first filter part 101 in the box body 1. The first filter part 101 uses water to cool down and flush the exhaust gas, so that the temperature of the exhaust gas is reduced, and some harmful substances in the exhaust gas are dissolved in the water, and some dirt is flushed to achieve the first filtration of the exhaust gas. The second filter part 102 then absorbs the moisture containing harmful parts in the exhaust gas. Finally, the third filter part 103 absorbs the harmful substances in the exhaust gas. The filtered exhaust gas can be discharged from the exhaust port 3, which will not only not pollute the environment, but also will not harm the human body.

The water pump 202 will transport water to the top of the wet curtain 201, and the water will fall from the top of the wet curtain 201 to soak the entire wet curtain 201. When the exhaust gas passes through the wet curtain 201, the wet curtain 201 will cool the exhaust gas, and can dissolve some harmful substances in the exhaust gas in water, while flushing down some dirt in the exhaust gas, and performing preliminary filtration on the exhaust gas.

[0031] Specifically, a water trough 203 is provided on the top of the wet curtain 201, a water receiving trough 204 is provided on the bottom of the wet curtain 201, and an inlet pipe 205 is connected to the water inlet end of the water pump 202, and an outlet pipe 206 is connected to the water outlet end of the water pump 202. The inlet pipe 205 is connected to the water receiving trough 204, and the outlet pipe 206 is connected to the water trough 203. The water pump 202 pumps the water in the water receiving trough 204 through the inlet pipe 205, and transports the water to the water trough 203 at the top of the wet curtain 201 through the outlet pipe 206. The water in the water trough 203 enters the wet curtain 201, falls from the bottom of the wet curtain 201 and enters the water receiving trough 204, thereby realizing the recycling of water.

[0032] In addition, there are water outlet holes 207 arranged at intervals along the length direction of the gutter 203. The water in the gutter 203 flows out through the water outlet holes 207. The water outlet holes 207 are arranged at intervals along the length direction of the gutter 203, so that the water can soak the entire wet curtain 201, thereby further improving the filtering effect on the exhaust gas.

[0033] Preferably, a mounting bracket 301 and a water pump 202 are provided on the side of the box body 1. The water pump 202 is arranged on the mounting bracket 301 so that the water pump 202 can move with the box body 1, thereby making it easier to connect and install with the oven.

[0034] like Figure 1-5 As shown, further explanation of the implementation methods of the second filter part 102 and the third filter part 103 in this embodiment, the second filter part 102 is a water-absorbent sponge. The second filter part 102 can absorb the moisture in the exhaust gas filtered by the first filter part 101, which can not only ensure the dryness of the exhaust gas, but also can further absorb the water carrying harmful substances, thereby improving the filtering effect.

[0035] The second filter unit 102 can prevent moisture from entering the activated carbon of the third filter unit 103 , thereby increasing the service life of the third filter unit 103 .

[0036] In addition, the third filter unit 103 is activated carbon, which can absorb harmful substances in the exhaust gas, further improving the filtering effect and preventing the exhausted exhaust gas from causing pollution.

[0037] Preferably, a sliding track 302 is provided in the housing 1 , and a sliding channel 303 for the third filter unit 103 to slide is formed between the sliding tracks 302 . The third filter unit 103 can slide along the sliding channel 303 , which makes it easier to install and replace the third filter unit 103 .

[0038] In some other embodiments, a spacing bracket 304 is provided between the second filter section 102 and the third filter section 103, and an air hole 305 is formed on the spacing bracket 304. The spacing bracket 304 is supported in the housing 1, which can not only improve the structural strength of the entire housing 1, but also filter the second filter section 102 and the third filter section 103 separately to avoid contact between the second filter section 102 and the third filter section 103, so that the water in the second filter section 102 enters the third filter section 103, thereby affecting the life of the third filter section 103.

[0039] A clamping edge 307 is formed on the spacing bracket 304 , and the clamping edge 307 abuts against the second filter part 102 from both sides, thereby fixing the second filter part 102 .
