Abstract
The invention discloses a steam exchanger for a photographic paper coating machine. The steam exchanger comprises multiple heat exchange units. The heat exchange units are connected in parallel. A concentric-square-shaped pipe is arranged in each heat exchange unit. A steam inlet A is formed in the lower side wall of each heat exchange unit, a thermal medium outlet is formed in the upper side wall of each heat exchange unit, a steam inlet B is formed in the rear side face of each heat exchange unit, a cold medium inlet is formed in the right side face of each heat exchange unit, and a cold medium outlet is formed in the left side face of the each heat exchange unit. All the steam inlets and the thermal medium outlets are connected with branch pipelines. All the branch pipelines are connected with corresponding main pipelines. All the branch pipelines connected with the steam inlets B are each provided with a flow regulation valve. A branch pipe is arranged at an inlet of each concentric-square-shaped pipe. The heat exchange units are connected in parallel, and the branch pipes are arranged on the concentric-square-shaped pipes; when one of the heat exchange units breaks down, other heat exchange units can operate continuously; and if heat is not enough, the quantity of steam is increased by opening the flow regulation valves on the branch pipelines connected with the steam inlets B, and the temperature is raised.
Description
Technical field
The present invention relates to a kind of steam exchanger, particularly to a kind of steaming for photographic paper coating machine
Vapour exchanger.
Background technology
Drying in printing paper manufacturing process is a most important link, and present processing technology is by drying
Case is dried, and wherein steam exchanger is one of them critical piece.Steam exchange the most in an oven
Device only one of which heat exchange unit, and only one of which steam inlet, if heat exchange unit is broken, be necessary for
Decommission, reduce work efficiency.
Summary of the invention
In order to solve the problem in the presence of background technology, present invention employs techniques below scheme:
A kind of steam exchanger for photographic paper coating machine, including several heat exchange units, institute
State several heat exchange units in parallel, inside each heat exchange unit described, be provided with back-shaped pipe, under
Sidewall is provided with A steam inlet, and upper side wall is provided with thermal medium outlet, and trailing flank is provided with B steam
Import, right flank is provided with cold medium entrance, and left surface is provided with cold media outlet, and described each steams
Vapor inlet and thermal medium outlet are respectively connected with branch pipe(tube), and each branch pipe(tube) described is main with each respectively
Pipeline connects, and each branch pipe(tube) of described B steam inlet is provided with flow control valve, described time
It is provided with arm at shape tube inlet.
Further, described back-shaped pipe arm is vertical with supervisor.
Further, the angle between back-shaped pipe arm and supervisor is more than or less than 90 degree.
Further, described heat exchange unit at least two.
Several heat exchange units are in parallel, and back-shaped pipe is provided with arm, when one of them is broken,
Other several heat exchange units can continue to run with, if heat is inadequate, can open B steam
Increase quantity of steam on entrance branch road, improves temperature.

Detailed description of the invention
See accompanying drawing, a kind of steam exchanger for photographic paper coating machine, hand over including several heat
Changing unit, several heat exchange units described are in parallel, are provided with inside each heat exchange unit described
Back-shaped pipe, lower wall is provided with A steam inlet, and upper side wall is provided with thermal medium outlet, and trailing flank sets
Having B steam inlet, right flank is provided with cold medium entrance, and left surface is provided with cold media outlet, institute
Stating each steam inlet and thermal medium outlet is respectively connected with branch pipe(tube), each branch pipe(tube) described is respectively
Being connected with each main pipeline, each branch pipe(tube) of described B steam inlet is provided with Flow-rate adjustment
Valve, is provided with arm at described back-shaped tube inlet.
Preferably, described back-shaped pipe arm is vertical with supervisor, can according to the mouth of pipe towards
Direction, B steam inlet is located at any one side of heat exchange unit.
Preferably, the angle between back-shaped pipe arm and supervisor is more than or less than 90 degree, back-shaped
Pipe arm defines a bigger entrance with supervisor intersection, has a buffering to make to steam stream
With.
Preferably, described heat exchange unit at least two, heat exchange unit number can root
Increase according to the heat needed.
By the way of explanation, only describe some one exemplary embodiment of the present invention above, undoubtedly,
For those of ordinary skill in the art, in the case of without departing from the spirit and scope of the present invention, permissible
By various different modes, described embodiment is modified.Therefore, above-mentioned accompanying drawing and be described in this
It is illustrative in matter, should not be construed as the restriction to the claims in the present invention protection domain.
