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.
Refer to Fig. 1-3, a kind of deacidifying flue gas device, including extracting tower 1, nipple 2 and air-introduced machine 5, set in extracting tower 1
Having spray gun 11, spray gun 11 to be provided with shower nozzle 111, shower nozzle 111 is made by acid-alkali-corrosive-resisting material, and shower nozzle 111 is arranged down,
Spray gun 11 sprays the alkali liquor after atomization in extracting tower 1.Nipple 2 outer wall is stainless steel layer 21, and nipple 2 inwall is polytetrafluoro
Pvdf layer 22, nipple 2 is between extracting tower 1 and air-introduced machine 5, and 1 time head tower wall of extracting tower is provided with opening 12, and opening 12 is with short
Adapter 2 one end connects, and nipple 2 other end is connected with the air-introduced machine port of export 51.Wherein, the acid-alkali-corrosive-resisting material of shower nozzle 111
The pottery strong for acid-alkali-corrosive-resisting ability or titanium alloy.
This deacidifying flue gas device also includes hemispherical dome joint 3 and flange 4, and opening 12 and nipple 2 one end are by flange 4
Connecting, nipple 2 other end is connected by flange 4 with round mouth one end of hemispherical dome joint 3, the square opening of hemispherical dome joint 3
One end is connected by flange 4 with the air-introduced machine port of export 51.
During deacidifying flue gas device deacidification, when the flue gas burned by air-introduced machine 5 band to the air-introduced machine port of export 51, depend on
Secondary through hemispherical dome joint 3 with nipple 2, enter in extracting tower 1, now the temperature of flue gas is 155 DEG C, and the acid in flue gas is dense
Degree height, the spray gun 11 in extracting tower 1 sprays the alkali liquor after atomization in tower, is used for neutralizing the acid in flue gas, the flue gas after deacidification
Flow out from extracting tower 1 top, enter follow-up tail gas clean-up technique.But in the flue gas before deacidification, acid concentration is high, easily corrodes spray
The shower nozzle 111 of rifle 11, owing to shower nozzle 111 is made by acid-alkali-corrosive-resisting material, this acid-alkali-corrosive-resisting material is pottery or titanium
