[0002] Industrial waste gas generated by manufacturing enterprises is the main source of air pollution. When untreated waste gas enters the atmosphere, it will cause extremely serious air pollution. Therefore, it is inevitable to treat industrial waste gas. At present, the waste gas is mainly treated by dust removal, desulfurization and denitrification. During the treatment, the industrial waste gas is mainly dusted first, and then ammonia water is used to denitrify the waste gas.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1: Reference Figure 1-Figure 3, an integrated device for dust removal, desulfurization and denitrification of industrial waste gas, comprising: a first treatment tank 1 and a second treatment tank 2, and also comprising: a first threaded cover 109, threadedly connected to the first treatment tank 1, a connecting pipe 110 is fixedly connected between the first threaded cover 109 and the bottom of the second treatment tank 2; a second threaded cover 202, threadedly connected to the second treatment tank 2, and an exhaust port 203 is opened on the second threaded cover 202; a partition 104, fixed in the first treatment tank 1; a fixing pipe 3, fixed on the lower side of the partition 104; a first cavity 107, arranged on the upper side of the partition 104; a second cavity 10 8, arranged on the lower side of the partition 104; a plurality of nozzles 301, fixed in the fixed tube 3; an air pump 101; an air inlet pipe 102, arranged between the air pump 101 and the second cavity 108; a liquid supply component for supplying liquid to the fixed tube 3; a first discharge port 103, arranged on the lower side of the first treatment tank 1; a second discharge port 111, arranged on the first treatment tank 1, and the second discharge port 111 is matched with the partition 104; a third discharge port 204, arranged on the lower side of the second treatment tank 2; an exhaust pipe 105, arranged on the partition 104; a one-way valve 106, arranged in the exhaust pipe 105.

[0023] When treating the industrial waste gas, first add a proper amount of ammonia water into the second chamber 108 , and then add a sufficient amount of ammonia water into the first chamber 107 .

[0024] The exhaust gas is transported to the lower side of the first treatment tank 1 through the air pump 101 and the air inlet pipe 102, and the exhaust gas enters the ammonia solution in the second cavity 108. The liquid supply component transports the ammonia solution to the nozzle 301 to spray it out in the form of mist. The exhaust gas first contacts with the ammonia solution stored at the bottom for dust removal, and then contacts with the atomized ammonia solution. At this time, the ammonia solution can simultaneously remove dust and denitrify the exhaust gas. At this time, the exhaust gas enters the first cavity 107 through the exhaust pipe 105, and contacts with the ammonia solution in the first cavity 107, thereby performing secondary denitrification treatment on the exhaust gas, thereby effectively improving the treatment effect on the exhaust gas, and can effectively prevent the large amount of dust contained in the ammonia solution from affecting the treatment effect on the exhaust gas.

[0025] The waste gas after denitrification treatment enters the connecting pipe 110, and then enters the second treatment tank 2, contacts with the lime solution, and performs desulfurization treatment on the waste. The integrated treatment equipment is used to effectively improve the treatment efficiency and effect of the waste gas.

[0026] Example 2: Reference Figure 1-Figure 3 , an integrated device for dust removal, desulfurization and denitrification of industrial waste gas, is basically the same as Example 1, and further, the liquid supply component includes a pump 302 fixed on the first treatment tank 1, a liquid inlet pipe 303 is fixedly connected between the pump 302 and the fixed pipe 3, and a liquid suction pipe 304 is provided at the input end of the pump 302, and the liquid suction pipe 304 is connected to the bottom of the first treatment tank 1.

[0027] It also includes a purification box 305, in which a filter plate 306 is arranged, a sealing cover plate 308 is arranged on the upper side of the purification box 305, and the end of the liquid extraction pipe 304 away from the pump 302 is arranged on the upper side of the filter plate 306, and a connecting pipe 307 is fixedly connected between the bottom of the purification box 305 and the bottom of the first processing tank 1.

[0028] The ammonia solution in the purification box 305 is extracted by the pump 302, and the purified ammonia solution is transported to the fixed pipe 3. At this time, negative pressure is generated in the purification box 305, and the ammonia solution in the second cavity 108 is pumped into the purification box 305 through the connecting pipe 307, and finally filtered through the filter plate 306. In general, the ammonia solution can be recycled and the ammonia solution can be effectively prevented from containing a large amount of dust that affects the treatment effect of the exhaust gas.

[0029] Example 3: Reference Figure 1-Figure 3 , an integrated device for dust removal, desulfurization and denitrification of industrial waste gas, which is basically the same as Example 1, and further, a first mesh plate 112 is provided on the upper side of the partition 104.

[0030] A second mesh plate 201 is fixedly connected inside the second processing tank 2 .

[0031] The first mesh plate 112 is magnetically connected to the partition plate 104 , and a first gap is provided between the first mesh plate 112 and the partition plate 104 .

[0032] The exhaust gas is divided into a plurality of small bubbles by the first mesh plate 112 and the second mesh plate 201, thereby effectively increasing the contact area between the exhaust gas and the lime solution and the ammonia water, thereby effectively improving the treatment effect of the exhaust gas.
