Problems solved by technology

In addition, since activated carbon is injected into the activated carbon pipeline to flow through the pipeline in a steady flow, the efficiency of activated carbon to adsorb dioxins in the exhaust gas is not good, so even if an excessive amount of activated carbon is used, the gaseous dioxins in the exhaust gas cannot be effectively removed , while increasing the cost of activated carbon

Embodiment 1

[0070] see figure 1 As shown, the exhaust gas treatment system 1 of this embodiment includes a circulating fluidized bed semi-dry acid removal device 10 (circulating fluidized bed semi-dry scrubber equipment), an inert substance 20, an activated carbon adsorption device (active carbon absorber equipment , ACAE) 30, and a bag dust collector 40.

[0071] The aforementioned circulating fluidized bed semi-dry acid removal device 10 includes a reactor 11, a collection equipment dust 12 connected with the reactor 11, a circulation storage tank 13 connected with the reactor 11 and the dust collection equipment 12 And an alkali agent injection device 14 connected with the reactor 11, the reactor 11 can be used to import a waste gas, and the alkali agent injection device 14 can be used to import an alkali agent. In the present embodiment, the dust collection equipment 12 is It is a cyclone dust collector.

[0072] The aforementioned inert substance 20 is contained in the circulation ...

Embodiment 2

[0076] see figure 2 As shown, the difference between the exhaust gas treatment system of this embodiment and that of Embodiment 1 is that the inner wall of the delivery pipe 31 is provided with a plurality of spoiler structures 312, and these spoiler structures 312 are bumps, and this part has bumps The passage cross-sectional area of ​​the conveying pipe 31 is smaller than the passage cross-sectional area of ​​the conveying pipe 31 of the other parts.

Embodiment 3

[0078] The waste gas treatment system of this embodiment is different from that of Embodiment 1 in that the dust collection device 12 is a louver type inertial dust collector.

[0079] Application of the waste gas treatment system of the present invention

[0080] see image 3 As shown, when the exhaust gas treatment system 1 of Embodiment 1 of the present invention is used in an incinerator, the circulating fluidized bed semi-dry acid removal device 10 is connected with a boiler 60 by a conduction pipe 50, and an induced fan 70 It is connected with the bag dust collector 40 , and a chimney 80 is connected with the induced fan 70 .

[0081] Method of using exhaust gas treatment system of the present invention

[0082] Example 1

[0083] see Figure 4 As shown, the aforementioned incinerator equipped with the waste gas treatment system 1 of the present invention is equipped, and the quartz sand in the circulating storage tank 13 is injected with a wind speed of 6 to 10 mete...

Abstract

The invention provides an exhaust gas treatment system and a usage method thereof. The exhaust gas treatment system comprises circulating fluidized bed semi-dry scrubber equipment and an inert material provided within the circulating fluidized bed semi-dry scrubber equipment. The exhaust gas treatment system of the invention adopts the design of containing the inert material within the system. When the exhaust gas treatment system is in use, the inert material and an alkali agent form a fluidized dioxin-removal composition. A longstanding problem that the alkali agent sticks on the inner wall of a reactor when a gas suspension absorber (GSA) is applied for exhaust gas treatment is solved. Practical operation possibility of the GSA and the alkali agent in combination for acid gas removal is improved. In addition, what is proved is that the purpose of effectively removing the gas phase dioxin from the exhaust gas is achieved by using the fluidized dioxin-removal composition.

Description

technical field [0001] The invention relates to a waste gas treatment system, in particular to a high-efficiency system for treating gas-phase dioxins in waste gas. The invention also relates to methods of using exhaust gas treatment systems. Background technique [0002] Colorless and odorless dioxin is the poison of the century. It is produced in the waste gas caused by combustion. Dioxin exists in animals or fruits and vegetables, and then enters the human body through the food chain and is absorbed by the human body, causing many liver, immune system, muscle and joint diseases. Pain, miscarriage, deformed children, visual impairment and other diseases, so the treatment of dioxin is one of the most attention-grabbing problems now. [0003] The exhaust gas produced by incinerators or other combustion systems contains acid gases and toxic gases of dioxins. Generally, an alkaline agent absorption tower is used to remove acid gases, and activated carbon is used to absorb dio...
