Description

Technical Field

[0001] The utility model relates to the technical field of flue gas denitration, in particular to an ozone automatic regulating and dosing device for flue gas denitration. Background Art

[0002] There are two main types of flue gas denitrification technologies: dry method (selective catalytic reduction flue gas denitrification, selective non-catalytic reduction denitrification) and wet method. Compared with wet flue gas denitrification technology, the main advantages of dry flue gas denitrification technology are: low basic investment, simple equipment and process, high efficiency of removing NOX, no excessive water and waste treatment, and not easy to cause secondary pollution. In the process of flue gas denitrification, ozone needs to be transported to the inside of the tank, but in the process of transporting ozone, most of the ozone is transported by spraying, but this method of ozone transport cannot effectively control the pressure of ozone, resulting in the inability to effectively transport and spray ozone;

The new scheme can control the delivery amount of ozone by rotating the air supply pipe, better quantitatively deliver ozone, and deliver ozone by means of multiple air holes, so as to effectively control and adjust the delivery pressure of the gas and automatically deliver ozone;

[0004] The above-mentioned existing technical solution has the following defects: the trapezoidal gear is driven to rotate by a driving motor to make it cooperate with the gear ring, and then the air supply pipe on the right side of the gear ring is driven to rotate, so that the air outlet outside the air supply pipe is matched with the air diffusion hole outside the air supply pipe. The whole adjustment mechanism is relatively complicated, which increases the production and processing cost of the device and reduces its practicality. In view of the above situation, technical innovation is carried out on the basis of the existing ozone automatic adjustment and dosing device for flue gas denitrification. Utility Model Content
