Description
Technical field
The present invention relates to technical field of heat exchange such as electric power, environmental protection, chemical industry, the energy, in particular it relates to what a kind of convenience was overhauled
Pipe heat exchanger.
Background technology
For environmental protection, meet the discharge standard requirement of country, recycling heat is so as to reaching energy-conserving and environment-protective
Purpose, pipe type water-flue gas heat-exchange unit is widely used in thermal power generation and environmental protective chemical industry field, this heat exchanger principal mode is
Heat exchanger tube, header and external pipe assemble to form the heating agent circulatory system, are exchanged heat with flue gas, in order to make full use of cloth to be empty
Between, high efficient heat exchanging, set up on heat exchanger tube in respect of fin and arrange compact, gap very little between pipe row, in actual moving process
In due to containing moisture and ash content in flue gas, the corrosion and breakage of heat exchanger tube often occur after operation, after causing heating agent to reveal
Heat exchange and service life of equipment are influenceed, because structure limits, pipe heat exchanger maintenance is generally all first to bypass set of heat exchange tubes then
Investigated after shutting down by root, step is more, time length, and effect is often and not fully up to expectations, it is therefore desirable to a kind of rational in infrastructure
More convenient maintenance heat exchanger form, can quickly find and handle leakage problem, heat-transfer surface can be reduced as far as possible
Product wastes, and extends the uptime.
Through retrieval, the U of Chinese patent literature CN 204388656 (application number 201420869275.4) disclose a kind of heat exchange
Device, there are some heat exchange layers, each heat exchange layer has some heat exchange units, and the heat exchange unit is arranged including heat exchanger tube, same
Unit connecting tube is connected between the adjacent heat exchange unit of the heat exchange layer, in addition to is connected to the water inlet of the heat exchanger
Bypass connecting tube between main header and the main header of water outlet, described bypass are provided with interface in connecting tube, pass through the interface and institute
State the connection of unit connecting tube；Bypass connecting tube pipeline section corresponding with each heat exchange unit, which is provided with, bypasses on-off valve.When
During a certain heat exchange unit leak, the leakage unit is cut off, each heat exchange layer is not cut off integrally, and it is single not influence other heat exchange
The normal heat exchange of member, and the unbalanced problem of heat exchange caused by overcoming traditional approach, and the loss of heat exchange area is reduced as far as possible.
Through retrieval, the U of Chinese patent literature CN 203949548 (application number 201420346936.5) disclose a kind of unit
Formula heat exchanger, it is characterised in that it include arrange from bottom to up support, bottom heat exchanger unit, middle part heat exchanger unit and
Top heat exchanger unit, bottom heat exchanger unit, middle part heat exchanger unit and top heat exchanger unit are disposed as front and rear cloth
Two groups put, connected between bottom heat exchanger unit, middle part heat exchanger unit and top heat exchanger unit by installing plate, bottom
Connected between the header of portion's heat exchanger unit, middle part heat exchanger unit and top heat exchanger unit by header bend pipe.The list
First formula heat exchanger reduces stock with that can reduce cost of transportation, the advantages of can going to carry out in-site installation using producer.
Through retrieval, the U of Chinese patent literature CN 205262272 (application number 201520938577.7) disclose a kind of
Tube Sheet of Heat Exchanger group and heat exchanger, including pipe group body, valve body, valve element is connected with the valve body, and the valve body welds with capping
Into a valve body assembly, the capping is welded on pipe group body.On the one hand tube assembly is allowed to process simple in construction, convenient welding,
Fast and effeciently heat exchanging device pipe group pipeline it can be inflated and deflation operation, so as to convenient to Product jointing, leak detection operation；
On the other hand, in the case where not destroying pipe group body, the leak detection of pipe group, operation of doing over again are facilitated.
The heat exchanger of above patent is disadvantageous in that although heat medium pipe is blocking design and operation, but once exchanges heat
Pipe is revealed, and inspection and maintenance is required for after equipment is out of service, and is merely able to integrally enter whole unit heat medium pipe
Row checks.It can not investigate in time, the influence in heat exchanging face is also larger after deactivated cell, summary feature, according to actual maintenance
Situation, it is necessary to designing one kind can judge online, online isolation, overhaul more convenient heat exchanger.
The content of the invention
For deficiency of the prior art, it is an object of the invention to provide a kind of pipe heat exchanger of convenient maintenance, setting
Once finding leakage during received shipment row, without special installation, without shutting down, you can overhauled and determined in outside heat exchanging pipe
Position processing.
To realize object above, the present invention provides a kind of pipe heat exchanger of convenient maintenance, including heat exchanger shell, heating agent
Pipe, heating agent control header, heat medium pipe are combined with unit form, control header to enter to the heating agent of each heat medium pipe by heating agent
The accurate distribution of row and control.
Preferably, a kind of pipe heat exchanger heat medium pipe of described convenient maintenance is combined with unit form, but between unit
It is independent mutually.
Preferably, a kind of unit of the pipe heat exchanger heat medium pipe composition of described convenient maintenance controls with heating agent respectively joins
Case is connected.
Preferably, a kind of pipe heat exchanger heating agent control header of described convenient maintenance can be to unit and list
Each heat medium pipe accurately distribute and control in member.
Preferably, a kind of pipe heat exchanger heating agent control header of described convenient maintenance is in hull outside, heat medium pipe
In enclosure interior, housing plays support and protection heat medium pipe effect.
It is online right that above-mentioned each preferred feature description can enable the pipe heat exchanger of the convenient maintenance of this kind to realize
Problem heat exchanger tube is accurately controlled, timely processing.
Compared with prior art, the present invention has following beneficial effect：
The pipe heat exchanger heating agent control Header portions of convenient maintenance of the present invention, which have, accurately to be divided connected heat medium pipe
With control function, the operational factor such as flow rate of heat medium, the temperature, pressure of bonding apparatus for often arranging heat medium pipe can be controlled to realize
The On line inspection of heat exchanger tube.
Existing heat exchanger is after unit leakage is found, it is necessary to close down whole heat exchanger or the direct side in units of unit
Pipeline heat exchanger, after system shutdown being manually entered device interior checks heat medium pipe, also needs to housing and changes if necessary
Heat pipe is cut and repaired, and hysteresis is compared in whole service work, and equipment is had a great influence.
Using the present invention, heat medium pipe is connected with heating agent control header, and header has to flow rate of heat medium essence in institute's connecting leg comb
Really distribution control function, after finding unit leakage, by the operation to header, it can in time check to go wrong and heat medium pipe and close
Close, the influence revealed to system operation is preferably minimized, directly repaired after system shutdown.With existing heat exchanger phase
The very first time that directly can occur than, service work in problem is carried out, and follow-up maintenance is also more conventional more convenient, during saving
Between and human cost.
