Abstract
The utility model discloses a central cylinder mounting structure of an adiabatic cyclone separator, which comprises a central cylinder, a steel frame and a plurality of support plates, wherein the steel frame is arranged outside the central cylinder; the method is characterized in that: a bent sealing cylinder is fixedly arranged on the outer side of the central cylinder below the beam, one end of the sealing cylinder is fixedly connected with the outer wall of the central cylinder, and the other end of the sealing cylinder is fixedly connected with the steel frame; the utility model discloses can prevent to leak because of the flue gas that a central section of thick bamboo radial expansion leads to, have the advantage that the leakproofness is good, can guarantee the normal operating of equipment.
Description
Technical Field
The utility model relates to a mounting structure for an adiabatic formula cyclone center section of thick bamboo.
Background
A circulating fluidized bed boiler of an existing power plant generally adopts a high-temperature heat insulation volute type cyclone separator, as shown in fig. 1, the upper end of a central cylinder 11 of the separator is connected with a steel frame 13 through a plurality of beams 12, the steel frame 13 is arranged on a plurality of supporting plates 14 on the inner wall of the cyclone separator, so that the central cylinder 11 is suspended and fixed on the inner wall surface of the cyclone separator, the weight of the central cylinder 11 is supported through the steel frame 13, and in order to ensure the sealing performance of the periphery of the central cylinder, a sealing steel plate 15 welded with the steel frame 13 is arranged on the periphery of the outer side of the central cylinder 11, so that the flue gas in the separator can be prevented from overflowing and plays a; however, in the using process, the central cylinder 11 generates radial expansion under the action of thermal stress, the sealing steel plate 15 is a rigid part and is easy to crack or fall off under the action of stress, so that smoke gas overflows, and the sealing property is poor.
Disclosure of Invention
The utility model aims at the above-mentioned not enough of prior art, provide an adiabatic formula cyclone center section of thick bamboo mounting structure, it can prevent to leak because of the flue gas that a center section of thick bamboo radial expansion leads to, has the advantage that the leakproofness is good, can guarantee the normal operating of equipment.
In order to achieve the purpose, the utility model discloses a central cylinder mounting structure of an adiabatic cyclone separator, which comprises a central cylinder, a steel frame arranged outside the central cylinder and a plurality of supporting plates, wherein one end of a plurality of beams is arranged on the steel frame, and the other end of the beams passes through the central cylinder; the method is characterized in that: a bent sealing cylinder is fixedly arranged on the outer side of the central cylinder below the beam, one end of the sealing cylinder is fixedly connected with the outer wall of the central cylinder, and the other end of the sealing cylinder is fixedly connected with the steel frame;
the bent sealing barrel has certain toughness, can deform in the radial direction under the action of stress, avoids generating cracks or falling off, prevents flue gas leakage caused by radial expansion of the central barrel, has the advantage of good sealing property, and can ensure the normal operation of equipment;
as a further improvement of the utility model, each beam also passes through a respective reinforcing plate fixedly connected with the inner wall of the central cylinder; the connecting strength of the central cylinder can be improved;
to sum up, the utility model discloses can prevent to leak because of the flue gas that a central section of thick bamboo radial expansion leads to, have the good advantage of leakproofness, can guarantee the normal operating of equipment.
