Fig. 1 is a schematic structural view of the present utility model.
Detailed Description
As shown in fig. 1, the flue gas recovery device for high-temperature pickling comprises a tank body 1, wherein a flange cover plate 2 which is correspondingly matched is arranged at an opening at the top of the tank body 1.
A flue gas collecting port 3, an air input port 4, a first tank inlet 5 and a second tank inlet 6 are arranged on the flange cover plate 2. A collecting pipe 3a with one end extending into the tank body is inserted into the flue gas collecting port 3, an air pipe 4a with one end extending into the tank body is inserted into the air input port 4, a first inserting pipe 5a with one end extending into the tank body is inserted into the first tank inlet 5, and a second inserting pipe 6a with one end extending into the tank body is inserted into the second tank inlet 6.
The collecting pipe 3a, the air pipe 4 and the first inserting pipe 5a and the second inserting pipe 6a are vertically distributed on the flange cover plate 2, a flange valve 7 is coaxially communicated with the collecting pipe 3a, the air pipe 4a, the first inserting pipe 5a and the second inserting pipe 6a, and the lower end of the flange valve 7 is 25cm away from the flange cover plate.
A sealing cover 8 made of silica gel is arranged, and the sealing cover 8 is in a frustum shape. A set of first bolt mounting holes 8d corresponding to the mounting bolts of the flange cover plate 2 are formed in the end portion of the lower opening end of the seal cover 8. A group of openings 8b distributed corresponding to the flange valves 7 are arranged on the upper end surface of the sealing cover 8, and a group of second bolt mounting holes 8c distributed in a ring shape are also arranged on the outer side of each opening 8 b. The sealing cap 8 is coupled to the flange of the flange cover plate 2 and the flange valve 7 by first and bolt mounting holes at the upper and lower ends of the sealing cap 8 and bolts on the flange, thereby forming an airtight space 9 between the flange valve 7 and the flange cover plate 2.
A set of margin folds 8a are also provided on the outer circumferential surface of the sealing cap 8 to provide a margin for cap expansion when the sealing cap 8 is expanded.
Working principle:
the gas leaked from the smoke collecting port 3 and the air inlet port 4 is collected through the sealing cover, the first tank inlet port 5 and the second tank inlet port 6 are used for collecting gas, the air pipe supplements air into the tank body for maintaining the pressure balance in the storage tank, and the smoke is sucked out from the collecting pipe by the smoke collecting device positioned outside the production workshop. The problem of disordered leakage of gas in the prior art can not occur due to the existence of the sealing cover. When the output pipe and the input pipe are newly added on the tank body according to production needs, the sealing cover is only required to be provided with a hole, and a bolt mounting hole which is correspondingly matched with a mounting bolt of a flange valve on the new pipe is arranged outside the hole, so that the installation is convenient. Arrows in the figure are schematic representations of gas leakage.
