Device for preventing high-temperature thermal stress damage of a quench tower gas-phase feed port

Abstract

The application relates to the field of chemical production process equipment design, in particular to a device for preventing high-temperature thermal stress damage of a gas-phase feeding port of a quench tower, and more particularly to a device for preventing high-temperature thermal stress damage of a gas-phase feeding port of a quench tower, which comprises a stress receiving device and a stress absorbing device; the stress receiving device comprises a cylinder I and a lining cylinder, the cylinder I is communicated with the outer end of the lining cylinder, the outer side of the lining cylinder is sequentially provided with a conical shell and a cylinder II in the direction away from the cylinder I, and the conical shell and the cylinder II are filled with ceramic fibers between the conical shell, the cylinder II and the lining cylinder; the inner end of the cylinder II is fixed on the equipment body of the quench tower; the stress absorbing device comprises an outer sleeve and a connecting pipe, the connecting pipe is communicated with the internal pipeline of the quench tower, the connecting pipe is inserted into the outer sleeve, the inner end outer side of the lining cylinder is fixed on the inner wall of the outer sleeve, and the inner end of the lining cylinder and the end of the connecting pipe have a gap.
