Background technique

Combustion, as a way of supplying energy, serves the production and life of human beings and can be said to be everywhere. Also in the laboratory, various combustion experiments are also in an endless stream, so there are many kinds of exhaust gas and dust, such as CO produced by incomplete combustion, SO ₂ produced by S-containing substances, and used in combustion experiments Titanium dioxide solid particles and so on. Many people directly discharge the waste gas produced by combustion into the air, and some people will carry out simple treatment, but it cannot completely eliminate the waste gas and solid particles, which causes pollution to the atmospheric environment, so we should pay attention to this question.

Further, the exhaust gas inlet and the exhaust gas outlet are at the same height, and a filter screen is arranged in the exhaust gas outlet.

Further, there are three baffles, two of which protrude from the slots on the top surface of the box and are suspended in the box. The distance between the bottom of the baffle and the bottom of the box is 1/3 of the height of the box, and the other is installed on the In the slot on the bottom surface of the body, it is located in the middle of the two baffles, and the distance between the top of the baffle and the top of the box is 1/3 of the height of the box.

Further, the distance between the baffle in the middle and the baffles on both sides is equal, and the distance between them is 1/4 of the length of the box, so as to achieve the best adsorption effect.

Further, water can be recycled.

Further, solid particle adsorption material is placed in the filtering device to absorb the solid particles brought down by the water flow, and purify the circulating water so that it can be recycled.

When working, the nozzle produces fully atomized water mist to fill the entire box, and the 3 baffles are fixed by the card slot, mainly to change the trajectory of the exhaust gas, so that the exhaust gas and the water mist are fully mixed, increase the absorption of exhaust gas particles, and reduce the temperature , the final waste water enters the waste water filter device from the waste water outlet, and the filtered water is then used for spraying to achieve the function of water circulation and save water consumption.

Beneficial technical effect achieved by the present invention:

1. In the combustion experiment, it can absorb the fine particles added in the exhaust gas and other solid particles produced by combustion, and reduce the emission temperature.

2. In all kinds of experiments with tail gas, if there are a lot of solid particles, this device can be used for tail gas treatment.

3. In all kinds of production and life, this device can be used for dust treatment.

4. For the purification of indoor air, especially indoor dust, this device can also be used.

detailed description

In order to better understand the technical features, technical contents and technical effects of the present invention, the accompanying drawings of the present invention will now be described in more detail in conjunction with the embodiments.

As shown in Figure 1, the present invention provides a device for harmless treatment of tail gas, which mainly includes a tail gas treatment device and a waste water treatment device. The tail gas treatment device includes a box body 11 , a nozzle 1 , three baffles 4 and an observation window 8 , and the waste water collection device mainly includes a waste water filter device 6 . When working, several nozzles produce fully atomized water mist to fill the entire box, and the three baffles 4 are fixed by the slot 2, mainly to change the trajectory of the exhaust gas, so that the exhaust gas and the water mist are fully mixed, and the absorption of exhaust gas particles is increased. ,Reduce the temperature. The final waste water enters the waste water filter device 6 through the waste water outlet 5, and the filtered circulating water 7 is used for spraying again, so as to achieve the effect of water circulation and save water consumption.

The tail gas inlet 3 and the tail gas outlet 9 are located at the same height.

A filter screen 10 is arranged inside the exhaust gas outlet 9 .

The front panel is removable for easy cleaning.

The three baffles 4 are fixed by the slots 2 . It is used to prolong the residence time of exhaust gas in the box, so that exhaust gas and solid particles can be fully mixed with water mist to achieve the effect of dust removal and cooling.

The circulating water 7 can be recycled to achieve the effect of solving water resources.

The working principle of the present invention: the tail gas enters the box body 11 to bypass the baffle plate 4, and the nozzle 1 generates very fine and dense water mist to fully mix with the tail gas. When the tail gas exit 9 is near, the solid particles in the tail gas will dramatically decrease. The waste water in the tank 11 enters the filter device 6 through the waste water outlet 5, and the recycled water 7 obtained after filtration is passed into the nozzle 1 again to generate water mist, and the exhaust gas is discharged into the air after cooling and dust removal.
