Further, the left tube sheet and right tube plate pass through welding manner and heat exchanger tube and heat exchange plate is fixed on one
It rises, left tube sheet and right tube plate are fixed together with shell, are equipped on left tube sheet and right tube plate and the water conservancy diversion on heat exchange plate
The corresponding hole in hole.
Further, the deflector hole on the heat exchange plate is on heat exchange plate backwards to interlaced arrangement.
Further, the heat exchanger tube is located at shell internal upper part, and heat exchange plate is located at lower part in shell, right in the shell
End socket position is answered to be divided into two cavitys by partition, two cavitys are corresponding with heat exchanger tube and heat exchange plate respectively and are connected to.
To sum up, the advantageous effects of the above technical solutions of the present invention are as follows:
The present invention, which solves most of traditional heat exchangers, cannot coordinate asking for high temperature high voltage resistant and good heat exchange property
Topic, i.e., high-temperature and high-presure resistent heat exchanger heat exchange efficiency is generally all less high, and vice versa.Traditional heat exchangers are to there is phase transformation simultaneously
Heat transfer process cannot be guaranteed sufficiently to exchange heat, and multiple heat exchanger continuous works is needed just to complete the process, and this results in entire heat exchange
System overall cost and the raising for occupying volume.The present invention is able to satisfy the successive heat exchange demand of phase change fluid, completes the depth of the energy
Degree recycling has the advantages that energy-efficient, saving space occupied and heat-exchange system cost.

Feature and principle of the invention are described in detail below in conjunction with attached drawing 1-5, illustrated embodiment is only used for explaining
The present invention is not limited the scope of protection of the present invention with this.
As depicted in figs. 1 and 2, the invention include 5, two end sockets of shell, respectively left head 1 and right end socket 8, emptying connect
Pipe 2, left tube sheet 3, right tube plate 6 further include heat exchange plate 11 and heat exchanger tube 13.Shell is equipped between corresponding two sealing plates on shell
Side outlet adapter tube 4 and shell fluid entrance sleeve 10 are respectively equipped with emptying adapter tube 2 and hot side fluid inlet on the end socket at both ends
Adapter tube 7 corresponds to and is additionally provided with a hot side outlet adapter tube 9 on the end socket of hot side fluid inlet adapter tube 7.Multiple heat exchange plate splicing compositions
Heat exchange plate group is simultaneously fixed in the shell of heat exchanger, and deflector hole 14 is equipped on heat exchange plate.Also fixation is set heat exchanger tube
It sets in the shell of heat exchanger, heat exchange plate group and heat exchanger tube can form communicating passage.Left tube sheet and right tube plate pass through welding
Mode is fixed together with heat exchange plate and heat exchanger tube, and left tube sheet and right tube plate are fixed together with shell, on left tube sheet and the right side
Hole corresponding with the deflector hole on heat exchange plate is equipped on tube sheet.Heat exchanger tube is located at shell internal upper part, and heat exchange plate is located at shell
Internal lower part corresponds to end socket position in the shell by partition and is divided into two cavitys, two cavitys respectively with heat exchange plate and change
Heat pipe is corresponding and is connected to.
As shown in Figure 3 and Figure 4, the deflector hole on heat exchange plate increases heat exchange stream backwards to interlaced arrangement on heat exchange plate
Journey route, as shown in Figure 5.
It is construed in more detail, the fluid of hot side fluid is divided into tube side and plate journey by partition 12, logical into heat exchanger tube 13
The fluid and shell fluid in road exchange heat and are shunted by emptying adapter tube 2, and uncooled fluid is flowed out from emptying adapter tube 2, cold
Fluid after solidifying, which enters back into, to be continued to exchange heat with shell fluid in heat exchanger plates 11.Heat exchanger tube is above, and plate is below,
The problem of blocking heat exchange pipeline after hot side fluid condenses can be avoided the occurrence of.In addition to this, due to the heat exchange of condensing heat-exchange process
Coefficient is originally relatively high, so occurring heat transfer effect can also be kept good in tubulation even if the process, while again by pressure drop
Control is in a relatively low range.It is similar with plate heat exchanger for heat transfer process of the condensed fluid in plate beam, again
Because plate outer tunnel be we open due to compare flexibly, force flowing simultaneously again guarantee the side pressure drop it is not too large.Even for general
Logical liquid liquid heat transfer process, fluid and shell fluid heat transfer process, improve the synthesis heat exchanger efficiency of heat exchanger entirety in plate beam.
The unique plate pipe structure of double-flow plate heat exchanger, there is no the vibrating fatigue damages at baffle plate and tube supports
Problem, the ripple of itself can absorb thermal expansion stress, thus has longer service life and lower maintenance cost.This is not only dropped
Low space, weight, support construction and basal energy demand and cost, and Process Design is improved, improve equipment cloth
It sets and processing conditions, reduces the dosage of fluid, the exchange capability of heat of unit volume is 1.5~3 times of traditional tubular heat exchanger,
Has the characteristics that energy-efficient more saving space.
Double-flow plate heat exchanger is corrosion-resistant, high temperature high voltage resistant, while having well solved phase transformation condensed fluid phase
Successive heat transfer problem becomes the best heat exchanger of recycling high-temperature residual heat.Be widely used in steel, machinery, building materials, petrochemical industry, medicine,
In the industries such as non-ferrous metal metallurgy.With hot side steam, for the recirculated water of cold side, the technology by plate beam and tube bank, alternately puts by heat absorption
Heat, the heat of recovery waste heat steam, can allow heating agent residence time in heat exchanger longer to the maximum extent, and condensation is more filled
Point, condensate temperature can be controlled in reduced levels or sufficiently be condensed organic solvent and cold by heat exchanger under appropriate operating condition
But, the rate of recovery 3%~5% or so of solvent can be effectively improved, the maximum of vapor energy is improved and utilizes or reduce other heat
The outlet temperature of matchmaker, therefore there is apparent advantage at energy-efficient aspect.
Above-described embodiment is only the description that carries out to the preferred embodiment of the present invention, not to the scope of the present invention into
Row limits, without departing from the spirit of the design of the present invention, relevant technical staff in the field to various modifications of the invention and
It improves, should all expand in protection scope determined by claims of the present invention.
