Description

 The proposed technical solution relates to techniques for gas purification and can be used to protect the environment and, in particular, for the neutralization of flue gases.

 A device for neutralizing flue gases containing a chimney, a vacuum device, an air pipe, an air ionization unit is known. See application N 5024544 / 26-079270, class B 01 D 51/00.

 The disadvantage of this device is the difficulty of mounting the vacuum device in the chimney.

 A flue gas neutralization device comprising a chimney, a vacuum device, an air pipe, an air ionization unit is also known. See RU 1472118, 04/15/89, B 01 J 19/08.

 We take it for a prototype.

 The disadvantage of this device is the difficulty of mounting the discharge device on the chimney.

 Distinctive features of the proposed technical solution is that instead of a vacuum device, an air pipe is used, lowered at one end into the chimney, and the other end is connected to the air ionization unit. The draft, which occurs in the chimney due to the difference in the discharge of air at the zero mark and at the highest point, will facilitate the suction of ionized air from the ionization unit and feed it into the chimney to neutralize the flue gases. The end of the air pipe, lowered into the chimney in contact with the high temperature of the flue gases, is made of refractory metal, for example titanium, so as not to warp it.

 The proposed technical solution meets the criterion of "Novelty", as it is not known from the prior art.

 The proposed technical solution corresponds to the "Inventive step", as it for the specialist explicitly follows from the prior art.

 The proposed technical solution is industrially applicable.

 The proposed technical solution is illustrated by graphic materials, where in FIG. - general view of the device.

 The graphic material shows: chimney 1, chimney 2, air ionization unit 3, air pipe 4, insulators 5 of the air ionization unit.

 Flue gases through the chimney 1 enter the chimney 2 and rush up due to the discharge of air at the upper point of the chimney 2. In the air pipe 4 connected to the air ionization unit 3 and the chimney 1, a vacuum is also created, due to which ionized air from unit 3 enters the chimney 1, then into the chimney 2, where it mixes with the flue gases and neutralizes them. The air ionization unit 3 is mounted on insulators 5. The ionization unit is grounded by a metal bus, one end of which is attached to the body of the ionization unit using a bolt and nut, and the other end is welded to the circuit of the workshop or chimney.
