Description
Technical field
The utility model relates to field of energy-saving technology, is specifically related to pipe type heat transfer energy saver.
Background technology
Pipe heat exchanger, it is most typical dividing wall type heat exchanger, and its application industrially has long history, and still dominate in all heat exchangers so far.Pipe heat exchanger mainly contains housing, tube bank, tube sheet and envelope first class sections composition, and how rounded housing is, and bundle of parallel tubes is equipped with in inside, and tube bank two ends are fixed on end plate.Pipe heat exchanger is difficult to thorough cleaning because of its special tubular structure, the heat exchange efficiency of pipe heat exchanger is caused to decline, energy consumption promotes, and impact and the removing technique of most enterprises and individual heat exchanging equipment fouling also rest on traditional " destructiveness " technique and the idea aspects such as machinery, water under high pressure, chemical pickling; Therefore be necessary to design a set of simple, safe, effective, easy-operating cleaning model to pipe heat exchanger.
In prior art, carry out two kinds of fluids of heat exchange in pipe heat exchanger, a kind of at Bottomhole pressure, a kind of in the outer flowing of pipe, the wall of tube bank is heat-transfer area.For improving extratubal fluid heat transfer coefficient, the horizontal baffle plate of some is installed in housing usually.Baffle plate not only can anti-fluid short circuit, increases fluid velocity, also force fluid by prescribed path repeatedly cross-flow by tube bank, less turbulence is greatly increased.And the medium flowed in pipe heat exchanger mostly is water, and the very easily fouling of this medium of water, the thickness that incrustation scale is attached to tube wall is thicker, the heat transfer effect of pipe heat exchanger is poorer, energy consumption is finally caused to rise, because pipe heat exchanger mostly is closed, cleaning is comparatively complicated, and traditional Chemical cleaning water treating method is the water treatment agent adding 3 kinds of not same-actions: corrosion inhibiter, antisludging agent and Biocidal algae-killing agent.Corrosion inhibiter can form epithelium in metal surface, prevents corrosion; Antisludging agent acts on the crystalline solid of the composition calcium carbonate forming dirt etc., makes its distortion, dislocation, distortion, hinders the growth of dirt with this; Biocidal algae-killing agent has inhibitory action to algea and bacteria, prevents it from breeding.Water Treatment method can reach good effect in theory, prerequisite is effective water quality stabilizer, professional operation and management and responsible operating personnel, due to above situation and feature, the effect often poor effect of Water Treatment, incrustation scale is assembled gradually again after bubble disclosed by hairbrush.Even if so current most of air conditioning cooling water system takes chemical water treatment method, also want during annual maintenance downtime in winter, to adopt hairbrush to disclose bubble cleaning condenser simultaneously, the copper pipe of pipe heat exchanger is not only straight but also long, particularly tubular heat exchanger, the condenser of such as central air conditioner main machine and evaporimeter, when current flow through Straight Pipes of Heat Exchanger, due to the existence of frictional resistance, and can not eliminate, no matter which kind of state current are in, the closer to the limit wall of tube wall, the flow velocity of water is slower, namely our laminar flow layer of often saying, the thickness of laminar flow layer depends on the flow velocity of pipeline, flow velocity is faster, laminar sublayer is thinner, the heat transfer type of laminar sublayer is generally conduction heat transfer, heat transfer efficiency is far below the convection heat transfer' heat-transfer by convection in centre, therefore the thickness increase heat exchange efficiency of reduction layer laminar sublayer is just extremely important!
The shortcoming and defect of prior art is, pipe heat exchanger is difficult to thorough cleaning because of its special tubular structure, the impact of most enterprises and individual heat exchanging equipment fouling and remove technique and also rest on traditional " destructiveness " technique and the idea aspects such as machinery, water under high pressure, chemical pickling; And think that equipment cleaning only just can be considered when having a strong impact on equipment and running simply, what it did not know incrustation scale is created on the energy consumption constantly affecting enterprise, engulfs the profit of enterprise.And the single expense in order to reduce cleaning, have selected cleaning method equipment being had to infringement and corrosion, causes the stagnation of scrapping and producing of equipment, paid than energy saver high the hundred times even cost of thousands of times.A lot of enterprise at present; adopt oxalic acid cleaning heat transmission equipment; each scavenging period all dare not more than two hours; thorough not because of what clean; so scavenging period from before become present 1 year three times annually; add the shutdown off-time of twice, indirectly cause loss to enterprise, and the waste water and waste liquid after cleaning causes great infringement to environment again.
Summary of the invention
