Abstract

The invention relates to heat exchange apparatus and can be used in the energy industry. The purpose of the invention is to provide uninterrupted cleaning of pipes when the annular space is supplied from bottom to top. The movement means of the partitions 3 is made in the form of a piston 5 with holes 6, alternately installed in the cavity of the housing I with overlapping its cross section and rigidly attached to the upper end of the rod 4 on which the valve 7 is freely installed, blocking the holes 6 of the piston 5, and in the upper section of the housing 1 against the holes 6 of the piston 5, at least one stop 8 is additionally installed, placed at the bottom end with the possibility of interaction with the valve 7 in the extreme top

Description

one

The invention relates to heat exchange apparatus and may be consumed in the energy industry.

The purpose of the invention is to provide non-rigorous cleaning of the pipes when the annulus is supplied from the bottom up.

The drawing shows a vertical heat exchanger.

The vertical heat exchanger comprises a housing 1, a bundle of heat exchange pipes 2 placed in the housing 1, and cleansing transverse partitions 3 mounted for movement, rigidly connected to each other and to their means of movement using an axial rod 4. The means for moving the partitions 3 is completed in the form of a piston 5 with holes 6 transversely mounted in the cavity of the housing 1 with its cross section overlapping and rigidly fastened to the upper end of the rod 4 on which the valve 7 is freely mounted, crossing the aperture 6 of the piston 5, and in the upper part of the housing 1 against the holes 6 of the piston 5 there is additionally installed at least one stop 8 placed with the lower end with the possibility of interacting with the valve 7 in the extreme upper position to release it from the piston 5.

Vertical heat exchanger operates as follows.

When the medium enters the annular space from the bottom up, the valve 7 with the piston 5 rises up and with the help of the rod 4 moves up the cleaning walls 3, which contact their cleaning elements with the outer surface of the pipes 2 and clean them when moving. When the upper position is reached, the valve 7 interacts with the stop 8 and stops, and the piston 5 continues to move upwards until the openings 6 are completely open. After opening the openings 6, the valve 7 is lowered downwards, and after equalizing the pressure above and below

0, under the piston 5, the piston 5 is lowered along with the baffles 3 before the piston 5 is seated on the valve 7. The holes 6 are closed and the cycle of movement of the piston 5 with the valve 7 is resumed. In this way, in the process of feeding the annular space medium, a constant cleaning of the outer surface of the heat exchange tubes is carried out.
