Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail so that the advantage of utility model and
Feature can be easier to be readily appreciated by one skilled in the art, thus makes protection domain of the present utility model apparent clear and definite
Define.
Referring to Fig. 1-2, a kind of deacidifying flue gas device attachment structure, including nipple 11, nipple 11 inwall is resistance to
Acid and alkali corrosion layer 112, nipple outer wall is stainless steel layer 111.Deacidifying flue gas device also includes extracting tower 2 and air-introduced machine 3, deacidification
Being provided with spray gun 21 in tower 2, down, spray gun 21 sprays the alkali liquor after atomization, extracting tower 2 lower end in extracting tower to the shower nozzle of spray gun 21
Tower wall is provided with opening 22, and opening 22 is connected with nipple 11 one end, and nipple 11 other end is connected with the air-introduced machine port of export 31.
This deacidifying flue gas device attachment structure also includes hemispherical dome joint 12 and flange 13, opening 22 and nipple 11
One end is connected by flange 13, and nipple 11 other end is connected by flange 13 with round mouth one end of hemispherical dome joint 12, sky
Square opening one end of square joint 12 is connected by flange 13 with the air-introduced machine port of export 31 circularly.Wherein, acid-alkali-corrosive-resisting layer can be adopted
With conventional acid-alkali-corrosive-resisting material, in the present embodiment, the preferably politef material as acid-alkali-corrosive-resisting layer 112.
During deacidifying flue gas device deacidification, when the flue gas burned by air-introduced machine 3 band to the air-introduced machine port of export 31, depend on
Secondary through hemispherical dome joint 12 with nipple 11, enter in extracting tower 2, now the temperature of flue gas is 155 DEG C, the acid in flue gas
Concentration is high, and the spray gun 21 in extracting tower 2 sprays the alkali liquor after atomization in tower, is used for neutralizing the acid in flue gas, the cigarette after deacidification
