[0002] There are many methods for purifying nitrogen oxides in flue gas and other waste gases. The most widely used method is the selective catalytic reduction (SCR) method that uses catalysts to promote the NOx reduction reaction. This process system is relatively simple, occupies a small area, and produces no or very little harmful by-products. It is adopted by most power plant boilers.

[0003] A low-temperature denitration device disclosed in the Chinese patent application publication specification CN219399440U specifically relates to the field of low-temperature denitration technology, including a denitration tank. The utility model sets a dust removal component, smoke and dust impurities are filtered through a filter screen, a vibration motor is started to drive a second vibration ring to achieve high-frequency vibration, the second vibration ring drives multiple vibration springs to achieve vibration, and the first vibration ring makes the filter screen vibrate, so that the filter screen can also remove dust inside the denitration tank, avoiding blockage caused by smoke and dust impurities.

[0004] Although the above scheme can use a filter to avoid blockage caused by smoke and dust impurities, the low-temperature denitrification equipment in the above patent is not convenient for rapid replacement of the filter device.

For this reason, we provide a low-temperature denitrification equipment to solve the above problems. Utility Model Content
