Description

Technical Field

[0001] The utility model relates to the technical field of flue gas denitration, in particular to a flue gas denitration device. Background Art

[0002] Flue gas denitrification refers to the process of reducing nitrogen oxides in combustion flue gas to nitrogen, thereby removing nitrogen oxides in the flue gas. According to the treatment process, it can be divided into wet denitrification and dry denitrification. At present, flue gas denitrification is mainly based on wet denitrification. During wet denitrification, denitrification is carried out by spraying denitrification solution on the flue gas.

[0003] However, most of the current flue gas denitrification equipment cannot filter and recover the denitrification liquid after the denitrification is completed, but directly discharges the denitrification liquid, which will cause a large amount of denitrification liquid waste in actual use, and also increase the cost of use; and it is also unable to purify the exhaust gas generated during denitrification, but directly discharges the exhaust gas together with the flue gas after denitrification, which will cause unnecessary impact on the surrounding environment in actual use. For this reason, we propose a flue gas denitrification equipment. Utility Model Content

[0027] Furthermore, the material of the denitrification equipment body 1 is set to stainless steel, which has the advantages that stainless steel itself has the advantages of strong corrosion resistance and high temperature resistance. Therefore, when the material of the denitrification equipment body 1 is set to stainless steel, it can prevent the denitrification liquid from corroding when the flue gas is denitrified for a long time, and the breakage will cause unnecessary influence on the service life, thereby improving the service life of the denitrification equipment body 1.

[0028] Furthermore, the filter screen 7 is slidably installed in the inner cavity of the square groove 5 through the slider 8 in the slide groove 6, and a handle 9 is fixedly installed on the front side of the filter screen 7.

[0029] Furthermore, a liquid extraction pipe 12 is sleeved between the top of the recovery box 11 and the right side of the denitrification equipment body 1, a pump body 13 is sleeved in the middle of the liquid extraction pipe 12, a liquid discharge pipe 14 is sleeved on the right side of the recovery box 11, and a valve 15 is arranged on the top of the liquid discharge pipe 14. Advantages: impurities contained in the denitrification liquid can be filtered and separated through the filter screen 7, so that the impurities remain on the filter screen 7, and the denitrification liquid flows to the bottom of the inner cavity of the denitrification equipment body 1, and then the denitrification liquid at the bottom of the inner cavity of the denitrification equipment body 1 is pumped to the recovery tank through the liquid extraction pipe 12 connected to the pump body 13. In the box 11, finally, turn the valve 15 counterclockwise to open the drain pipe 14 to discharge the filtered denitrification liquid for use, so that the user can filter and recycle the denitrification liquid used in flue gas denitrification, and avoid directly discharging the denitrification liquid to cause a large amount of waste and increase in use costs; and pull the handle 9 outward to drive the filter screen 7 to slide synchronously in the slide groove 6 through the slider 8 and be taken out of the square groove 5, so that the user can disassemble and clean the filter screen 7, and avoid the deterioration of the filtering effect due to inconvenient cleaning.

[0030] Furthermore, the inner cavity of the processing box 16 is equidistantly provided with a first purification layer 19 and a second purification layer 20, which are respectively provided by a carbon fiber purification layer and an activated carbon purification layer.

At the same time, when the bottoms of the four supporting legs 23 are set to be frosted, the friction resistance of the four supporting legs 23 in contact with the ground when supporting the denitrification equipment body 1 can be increased, which can prevent unnecessary shaking, thereby improving the stability of the device during operation.

[0033] Working principle: when in use, first put the denitrification liquid into the denitrification equipment body 1 through the liquid inlet pipe 2, and then draw the flue gas into the denitrification equipment body 1 through the exhaust pipe 3 connected to the first air pump 4, and then carry out the denitrification work.
