Example Embodiment

[0037] Example 1

[0038] The structure diagram of the vertical purification device of this embodiment is as figure 1 Shown:

[0039] The purifier for the strong acid component in the exhaust gas uses a plexiglass tube with a tube wall thickness of 4mm, an outer diameter of 300mm, and a height of 800mm to be placed vertically as the reactor shell 1, and a plexiglass plate with a thickness of 5mm is used to make a disc with a diameter of 300mm, and A circular hole with a diameter of 50mm is opened in the center of the disk, and the organic glass disk is bonded to the bottom of the above-mentioned organic glass tube by using acetone to dissolve the organic glass powder as a binder to form the bottom cover of the reactor shell. The circular hole is the opening The gas inlet at the bottom of the reactor shell 1.

[0040] Cut out a plexiglass tube with an outer diameter of 50mm and a length of 300mm, and cut 20 slits with a width of 3mm and a length (along the plexiglass tube radial dire...

Example Embodiment

[0051] Example 2

[0052] The structural schematic diagram of the horizontal purification device of this embodiment is as follows: figure 2 Shown:

[0053] The purifier that emits strong acidic components in the exhaust gas uses a 4mm thick plexiglass plate to make a 500mm long, 300mm wide, and 300mm high shell frame. Use the same plexiglass plate to cut out 500mm×300mm plates and glue them to the shell frame. As the bottom surface, the reactor housing 1 is constituted. A circular hole with a diameter of 50mm was opened on one side of the reactor shell as an air inlet, and a plexiglass tube with an outer diameter of 50mm and a length of 300mm was cut, and one end of the plexiglass tube was cut with a saw blade at even intervals to cut a width of 3mm and a length (along the plexiglass tube). Radial) 20 40mm slits are used as the air distribution slits 4a. Insert the processed end of the air distribution slit 4a into the above-mentioned 50mm air inlet and protrude 50mm from the in...

Abstract

The invention discloses a purification device and method for strongly acidic components in exhaust gas. The purification device is characterized by comprising a reactor shell, an active material filling container arranged in the reactor shell and a bearing layer arranged between the reactor shell and the active material filling container. The top of the reactor shell is sealed through a sealing cover plate. The reactor shell is provided with a gas inlet, a gas outlet and a liquid outlet. A gas guide pipe is inserted into the active material filling container. According to the purification device, the exhaust gas containing the strongly acidic components is distributed through the bearing layer, enters the gas guide pipe and then enters the active material filling container through gas holes distributed in the gas guide pipe to make contact with an active material, the strongly acidic components are reacted with the active material to form salt, and purified exhaust gas is exhausted through an exhaust pipe.

Description

1. Technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to the purification technology of strong acidic gaseous pollutants in waste gas. 2. Background technology [0002] Various laboratories and industrial production workshops that use volatile acids often emit strong acid waste gas, mainly HCl, HF, HNO 3 And the anhydride gas molecule SO produced by the decomposition of the compound 2 , SO 3 , NO 2 , N 2 o 5 Wait. The strong acid substances in the exhaust gas not only cause great harm to human health, but also have strong corrosiveness, damage various electrical equipment, corrode various metal products, cause serious corrosion of doors and windows, and affect environmental cleanliness. [0003] At present, the purification technology for all kinds of strong acid pollutants discharged by enterprises mainly adopts scrubbers, and the strong acid gases are discharged up to the standard by spraying sod...
