Description
Technical field
This utility model is related to a kind of bilateral type heat exchanger hydroecium, and in particular in a kind of multiple row or multi-stage heat exchanger equipment
The water chamber structure connected between two equipment tube banks.
Background technology
From the point of view of the development trend of current generating set, what is arranged in Steam Turbine Regenerative System draws gas series increasingly
Many, corresponding heater series also accordingly increases.Meanwhile, the increase of the flow of condensate and boiler feedwater also with unit capacity
And increase, this is particularly evident in nuclear power generating sets, and the heater which results in original single-row arrangement cannot meet system requirements, and
It is to need using dually arrayed the demand to meet big flow.In addition, in double reheat power generation sets, arranging two steamings in parallel cold
Device scheme is also increasingly common.Such change, while unit efficiency is improved, also increased not to the pipe arrangement at scene
Few difficulty.The conduit fittingss such as longer feedwater piping, more elbows, threeway, not only increase construction cost, also increase pipe
The pressure loss in road, affects unit efficiency.
Utility model content
Problem to be solved in the utility model is the arrangement for how merging two heat exchanger tubes in systems, makes system
The arrangement of pipeline is more simplified.
In order to solve the above problems, this utility model provides a kind of bilateral type heat exchanger hydroecium, it is characterised in that include
Hydroecium, the two ends of hydroecium are connected with tube bank one, tube bank two by tube sheet one, tube sheet two respectively, are provided with hydroecium demarcation strip in hydroecium,
Hydroecium is divided into hydroecium demarcation strip the two parts for being connected with feedwater outlet pipe, feed-water inlet pipe respectively, makes tube bank one, tube bank dimorphism
Into parallel-connection structure；Or hydroecium demarcation strip hydroecium is divided into connect with feedwater outlet pipe respectively, connect with feed-water inlet pipe, hydroecium
Two ends connect this three part, make tube bank one, tube bank dimorphism into cascaded structure.
Preferably, the hydroecium is cylinder.
Preferably, the hydroecium is provided with inspection manhole.
Two-way type hydroecium can apply each position in heat regenerative system.The equipment in parallel for two tube sides, can be with
Directly merged by using bilateral type hydroecium, making two tube banks, during system can be saved, need originally the parallel pipeline for configuring
And threeway.For the equipment of two tube side series connection, it is also possible to directly merged by using bilateral type hydroecium, making two tube banks,
Originally the connecting pipe for arranging is needed during system can directly be saved.
The profile of bilateral hydroecium is cylindrical tube figure formula, and cylindrical hydroecium internal diameter is according to the horicycle for restraining cloth bore region
It is determined that, wall thickness is passed through and is calculated then according to design pressure and design temperature.
When the tube bank of two equipment is to be arranged in parallel, hydroecium internal structure is monoblock rectangular partition plate, demarcation strip
Four edges are tightly connected with hydroecium inwall and tube sheet respectively.So, hydroecium is just divided into upper and lower two chambers by rectangular partition plate,
Feedwater outlet pipe, feed-water inlet pipe are located in the different piece of cylindrical hydroecium, and two parts are restrained by both sides respectively up and down
Connection；When two equipment tube banks are arranged in series, inside hydroecium, the left and right sides is respectively arranged a conventional hydroecium point
Hydroecium stack shell is divided into three separate chambers by dividing plate.The import and export adapter of tube side is respectively provided at both sides two separate chambers
On.So tube side medium can pass sequentially through two tube banks by tube-side inlet adapter into after hydroecium, finally export from tube side
Adapter is flowed out, and completes the heat exchange of two tube banks.
