The liquid feed distributor can solve the problem that the original distributor structure has distribution dead zone at the distribution center, and can reduce the overhauling work load and overhauling difficulty of the distributor under the premise of realizing uniform distribution.
Description
Technical field
The utility model relates to a kind of liquid feed distributor structure that is used for lamella heat exchanger.
Background technology
Lamella heat exchanger is present a kind of advanced person's heat exchanger structure form in the world, with plate type heat exchanging element, and replaces the rubber cushion sealing of common plate type heat exchanger in the welded seal mode, has increased substantially the serviceability temperature and the bearing capacity of plate type heat exchanger.
In the shell-and-plate feed exchanger, cold material is made up of liquid charging and two kinds of processing mediums of recyclegas, in existing process unit, this two media is entered heat exchanger and is mixed in heat exchanger by pipeline separately, its mixed effect quality directly influences the heat exchange efficiency of heat exchanger, and mixed effect depends on the distribution quality of liquid feed distributor.
In existing feed exchanger, distributor adopts central tubular or T shape structure usually, and its topmost characteristics are that feeding line is nested in the gas line, so feeding line is bigger to the distribution influence of gas, cause the distribution dead band in distribution center zone usually; In addition, in case feeding line goes wrong (as distribution hole plug or fouling), feeding line need be extracted out from gas line and be handled, maintenance workload is big, maintenance difficulty height, poor operability.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid feed distributor for lamella heat exchanger, to solve the problem in original structure of distributor distribution center distribution dead band, is realizing under the equally distributed precondition, reduces distributor maintenance workload and maintenance difficulty.
The technical solution of the utility model:
Described liquid feed distributor for lamella heat exchanger, form by charging access tube and charging distributor pipe, liquid feed distributor is positioned at independent setting the outside the gas piping, the charging distributor pipe of liquid feed distributor radially offers multiple row distribution hole, and charging access tube one end of liquid feed distributor is communicated with the tube wall place of charging distributor pipe outer end; Feed distributor is connected with the plate Shu Shixian of lamella heat exchanger by the charging distributor pipe, the charging distributor pipe radially offers multiple row distribution bore portion and is positioned at the plate bundle, charging distributor pipe outer end and charging access tube all are positioned at outside the plate bundle, in charging distributor pipe outer end end flange are installed.
On the described charging distributor pipe distribution hole offer angle and opening diameter is adjusted according to lamella heat exchanger plate area of beam size.
Described charging distributor pipe can be made up of one or more distributor pipes, and its structure can be I shape, U-shaped or H shape.
Between described charging distributor pipe and the charging distributor pipe, adopt fixed connection or removable connection.
Between described charging distributor pipe and the charging access tube, adopt fixed connection or removable connection.
The flexible connection that described charging distributor pipe and plate Shu Caiyong can extract out or be fixed on the plate bundle.
Between described charging access tube, be connected with the expansion joint of the thermal expansion difference between baffle bundle and housing.
Advantage of the present utility model and good effect are as follows:
1, feed distributor and gas piping do not take place relatedly, do not influence the even fluid distribution of gas piping.
2, feed distributor and plate bundle connected mode adopt fixed connection structure or removably connect, and can directly overhaul feed distributor, need not pass through gas pipeline, have simplified maintenance difficulty and workload.
3, feed distributor is with after the plate bundle is connected, and relative position is fixed, and has guaranteed the mixed effect of charging distribution effect and gas feed and liquid charging.
4, adopt mode or the releasable connection mode of fixedlying connected between charging distributor pipe and charging tube connector, simplified the mounting-dismounting programme of charging distributor pipe.
5, charging distributor pipe structure is formed I shape, U-shaped or H shape by one or more distributor pipe, optimizes the charging distributing homogeneity.
