[0017] The utility model will be further explained in connection with the drawings.

[0018] As Figure 1 shown, an air inlet pipe group for tail gas high-temperature treatment includes an upper pipe body 1, an automatic valve 2, a middle pipe body 3, a mechanical valve 4, a lower pipe body 5, and a double-head connecting component 6. The upper pipe body 1, the automatic valve 2, the middle pipe body 3, the mechanical valve 4, and the lower pipe body 5 are sequentially butt jointed to form an air inlet main pipe through the double-head connecting component 6. Figure 2 and Figure 3As shown, the double-ended connecting component 6 includes a center seat 7 and two connectors 8 symmetrically connected at either end of the center seat 7. The center seat 7 is sealed by the internally embedded connectors 8 at the various joints of the intake main pipe. To improve sealing, a sealing ring 13 is embedded on the outer periphery of the connector 8. A bracket 11 with plug-in sections 10 at its upper and lower ends is provided on the outer side of the center seat 7 by screwing the feed portion 9. The plug-in sections 10 at each end of the bracket 11 are radially inserted into the fixing holes 12 of the intake main pipe, with the joints 10 at the ends of the bracket 11 being separated by the joints of the intake main pipe. The present invention utilizes the double-ended connecting component 6 to quickly connect and axially position the various components of the intake main pipe. Compared to existing flange-mounted bolt and nut installation methods, this method requires fewer manually operated parts, improving installation efficiency. Furthermore, when the various components of the intake main pipe are axially positioned via the plug-in sections 10, loosening of the joints due to intake vibration is prevented, resulting in a more secure installation and ensuring safety.

[0019] like Figure 3 As shown, Figure 3 Taking the installation of the double-ended connecting component 6 as an example, a brief description is given: the middle seat 7 is connected to the input end of the automatic valve 2 and the output end of the upper tube body 1 through two connectors 8 at both ends. The input end of the automatic valve 2 and the output end of the upper tube body 1 are both provided with fixing holes 12 on the outside. The plug-in part 10 is aligned with the fixing hole 12 by rotating the plug-in bracket 11, and then the plug-in part 10 is inserted into the fixing hole 12 by rotating the screw feed part 9 until the screw feed part 9 is rotated to a fixed state, thus completing the installation of the double-ended connecting component 6. The automatic valve 2 and the middle tube body 3 of the air intake main, the middle tube body 3 and the mechanical valve 4, and the mechanical valve 4 and the lower tube body 5 are all connected and installed in the above manner. The operation is simple and convenient.

[0020] In the present invention, as a preferred embodiment, the screw feed portion 9 is a screw that is radially movably connected to the middle seat 7, and the inserting bracket 11 is movably sleeved on the screw. The inserting portion 10 is a cylindrical pin fixedly mounted on the inserting bracket 11, and the cylindrical pin is inserted and removed from the corresponding fixing hole 12.

[0021] In order to make the exhaust gas enter more smoothly and reduce resistance, the inner diameter of the middle seat 7 is the same as the inner diameter of the joint 8, and the outer end edge and the inner end edge of the joint 8 are chamfered to form a chamfered structure, wherein the chamfered structure of the outer end edge is for easy installation, and the chamfered structure of the inner end edge can reduce the resistance to the exhaust gas.

[0022] like Figure 1As shown, the mechanical valve 4 is a manual valve. The automatic valve 2 is a two-way electric valve, the upper pipe body 1 is connected to the inlet end of the two-way electric valve, the middle pipe body 3 is connected to the outlet end one of the two-way electric valve, and the outlet end two of the two-way electric valve is connected to the protection bypass pipe 14 through the double-head connecting component 6. The protection bypass pipe 14 can open the outlet end two of the two-way electric valve to lead the tail gas out of the equipment when the tail gas high-temperature treatment equipment fails, so that the possible dangerous situation can be prevented.

[0023] Since the lower pipe body 5 is connected to the gas inlet of the high-temperature combustion chamber, in order to heat-protect the gas inlet pipe, in the utility model, the lower pipe body 5 is a heat insulation pipe made of heat insulation material, and the middle pipe body part of the heat insulation pipe is in a wave-shaped heat dissipation structure shape with the radial outward expansion and inward shrinkage arranged alternately, so that the heat dissipation effect is further improved.

[0024] The above is only the preferred embodiment of the utility model, and it should be pointed out that for the ordinary skilled in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the utility model.
