Detailed Description

The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

The embodiment is as follows:

as shown in fig. 1-3, the gas-sealed emergency exhaust cap is an emergency device for opening a multi-chamber furnace under extreme emergency conditions (such as power failure in a workshop, failure of main equipment and the like), and after the emergency device is opened, flue gas in the multi-chamber furnace is directly exhausted into the atmosphere, the principle is that a smoke exhaust port is pressed through a heavy smoke exhaust cap, and flexible high-temperature-resistant materials such as packing and the like are adopted for sealing between the smoke exhaust cap and the smoke exhaust port, wherein the gas-sealed emergency exhaust cap comprises a smoke exhaust pipe 6, and a smoke exhaust port 7 is formed on the smoke exhaust pipe 6; the top of the smoke exhaust pipe 6 is fixedly provided with an air inlet jacket 4 along the transverse direction, the air inlet jacket 4 is connected with central shaft air, wherein the central shaft air is high-temperature air formed after heat exchange of the central shaft of the multi-hearth furnace, and the top of the smoke exhaust port 7 and the upper end surface of the air inlet jacket 4 are provided with smoke exhaust caps 1; the top side wall of the smoke exhaust pipe 6 is communicated with a flue 5, and air in the flue 5 enters the secondary furnace.

Gaps are formed between the end faces of the smoke exhaust cap 1 and the end face of the smoke exhaust port 7, wherein the number of the gaps of the smoke exhaust port is two, the outer side of the gaps of the smoke exhaust port is tightly pressed and sealed by packing, and the inner side of the gaps of the smoke exhaust cap is pressed back to the smoke through the guide notch 8 by middle shaft wind.

Specifically, a plurality of guide notches 8 are arranged and located on the end face of the smoke exhaust port 7, in this embodiment, 7 guide notches 8 are arranged and are distributed on the end face of the smoke exhaust port 7 in the same axial direction; the specification of the guide notch 8 is 100X15mm.

The end face of the air inlet jacket 4 is provided with a sealing filler 9, after the smoke exhaust cap 1 is closed, the smoke exhaust cap 1 compresses tightly the sealing filler 9 at the joint face of the air inlet jacket 4 by means of self gravity to form sealing, wherein the sealing filler 9 is a packing.

The smoke exhaust cap 1 comprises a top plate 11, a bottom plate 12 and a supporting plate 13; the top plate 11, the bottom plate 12 and the support plate 13 are fixedly connected and integrally formed; the structural strength and the firmness of the whole smoke exhaust cap 1 are improved, and the use safety is further ensured.

Wherein, the specification of the top plate 11 is a 304 stainless steel plate with the thickness of 3mm, and the specification of the bottom plate 12 is a 304 stainless steel plate with the thickness of 5 mm; the weight of the whole exhaust cap 1 is 260 kilograms, and the exhaust port 7 is pressed by the exhaust cap 1 to achieve the sealing effect.

Specifically, the bottom plate 12 of the smoke exhaust cap 1 is an oblique conical surface; so as to ensure that the smoke exhaust port and the upper end surface of the jacket are jointed at the same time.

The working principle of the embodiment is as follows: the middle shaft wind blows into the air inlet jacket 4 and then enters the flue 5 through a preset gap, finally enters the secondary furnace along with the flue gas, and forms an air seal by the pressure of the middle shaft wind through continuously blowing the middle shaft wind. Along with the increase of the opening times of the smoke exhaust cap, the packing sealing effect of the smoke exhaust cap and the end face of the jacket is poor, but only a small amount of middle shaft wind overflows into the air due to the 'air sealing' function of the middle shaft wind, and no side effect is generated due to the fact that the middle shaft wind is high-temperature air.

The device not only solves the problem that the sealing effect of the smoke exhaust device becomes worse along with the use, but also solves the problem that the oxygen is insufficient due to the fact that the secondary furnace burning tail gas needs sufficient oxygen, and the introduced high-temperature shaft air just makes up for the problem of insufficient oxygen, and meanwhile, the heat energy recovery of the shaft air is realized, and the self weight of the smoke exhaust cap can be lightened due to the sealing of the smoke exhaust cap in a gas sealing mode, so that explosion venting of a regeneration system is facilitated after lightening; the smoke exhaust cap is opened manually or electrically, and the axis wind is used for preventing smoke from overflowing under the condition that the normal smoke exhaust cap is not opened.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention; thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.

Although the reference numerals in the figures are used more here: the terms such as the smoke exhaust cap 1, the air inlet jacket 4, the flue 5, the smoke exhaust pipe 6, the smoke exhaust port 7, the guide notch 8, the sealing filler 9, the top plate 11, the bottom plate 12, the support plate 13 and the like do not exclude the possibility of using other terms; these terms are used merely to more conveniently describe and explain the nature of the present invention; they are to be construed in a manner that is inconsistent with the spirit of the invention.
