Each shell and tube heat exchanger comprises a shell, a copper heat exchange tube bundle, tube plates, baffle plates and tube cases, wherein the copper heat exchange tube bundles are positioned in the shells; the tube plates are used for fixing the copper heat exchange tubes; the baffle plates are arranged at intervals in the shells; the tube cases are positioned on the two sides of the shells respectively, and have Wood sealed structures; secondary water inlets and secondary water outlets are formed in the shells; cooling water inlets and cooling water outlets are formed in the tube cases. Each shell and tube heat exchanger is provided with a saddle, and the three shell and tube heat exchangers are fixedly connected through the saddles. The copper heat exchange tube bundles are explosively welded with the tube plates.
Description
technical field
The present invention relates under a kind of mine by copper heat exchanger tube water under high pressure water-to-water heat exchanger group.
background technology
Mine mostly is high gas environment, be located in underground more than 900 meters of left and right, if the high easily generation of environment temperature gas explosion, accident causes casualties, therefore need constantly to ore deposit delivered downhole cold water (cooling intermediate water) to guarantee personnel in the pit's safety, this just need to develop the water water-to-water heat exchanger using under a kind of applicable mine.Because of distant to delivered downhole, in pipeline, the drag losses of water is larger, need to use high-pressure hydraulic pump to supply water, the pressure of water is higher, design pressure is not less than 12MPa, and needs realization end difference to be not more than 4 ℃, needs to meet simultaneously and can be transported under mine by the hoistway of 2 meters of x2 rice.Because the thermal conductivity of copper is extremely strong, traditional copper hot pipe heat exchanger generally cannot adopt normal welding method to implement sealing, and conventional expanded joint mode connects heat exchanger tube and tube sheet, and expanded joint is only applicable to the equipment that design pressure is less than 4MPa, and connection weak effect, production efficiency is low.
summary of the invention
The technical problem to be solved in the present invention is to provide under a kind of mine by copper heat exchanger tube water under high pressure water-to-water heat exchanger group.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
Under a kind of mine, use copper heat exchanger tube water under high pressure water-to-water heat exchanger group, comprise the tubular heat exchanger of three full countercurrent flows in sequential series from high to low, each tubular heat exchanger includes housing, be positioned at the copper heat-exchanging tube bundle of housing, the tube sheet of fixed copper heat exchanger tube, the bobbin carriage with wood closure structure that interval is arranged on the deflection plate in housing and lays respectively at housing both sides, on housing, have intermediate water import and intermediate water outlet, on two bobbin carriages, have cooling water inlet and coolant outlet, each tubular heat exchanger is provided with saddle, three tubular heat exchangers are fixedly connected with by saddle, copper heat-exchanging tube bundle and tube sheet adopt explosive welding.
Under above-mentioned mine, with copper heat exchanger tube water under high pressure water-to-water heat exchanger Zu， intermediate water import department, impingement baffle is set.
Under above-mentioned mine, by copper heat exchanger tube water under high pressure water-to-water heat exchanger group, explosive welding adopts cylindrical shape medicine box holding medicine, and medicine box is made by the thick toilet paper of 0.6mm.
Under mine, by copper heat exchanger tube water under high pressure water-to-water heat exchanger group, three tubular heat exchangers, consist of, detachable and assembling, meets and is transported to the requirement under mine by narrow mine road.Three tubular heat exchangers are in sequential series and be fixedly connected with by saddle from high to low, meet the requirement in space under mine.The bobbin carriage with wood closure structure meets the safety requirements that pipe lateral pressure is not less than 12MPa, and hydroecium is removable, facilitates repair and maintenance.Copper heat-exchanging tube bundle and tube sheet adopt explosive welding, and bonding strength is high, and production efficiency is high, and copper pipe deflection is little.By series system, improved the flow velocity of water in copper heat exchanger tube, having lengthened mobile distance also makes shell both sides water fully carry out heat exchange, the full counter-current flow of shell both sides hydromining, and adopt the high copper heat exchanger tube of thermal conductivity, make the heat exchange efficiency of heat exchanger high, can realize end difference and be less than 4 ℃, thereby make compact equipment, cost is low, and occupation of land space is little.

In figure: 1 bobbin carriage, 2 coolant outlets, 3 impingement baffles, 4 intermediate water imports, 5 bronze medal heat exchanger tubes, 6 housings, 7 deflection plates, 8 bobbin carriages, 9 cooling water inlets, 10 intermediate water outlets, 11 saddles, 12 tube sheets, 13 protective layers, 14 detonators, 15 explosives, 16 tubular heat exchangers.
The specific embodiment
As shown in Figures 1 to 4, under mine, by copper heat exchanger tube water under high pressure water-to-water heat exchanger group, comprise the tubular heat exchanger 16 of three full countercurrent flows in sequential series from high to low.Each tubular heat exchanger includes housing 6, is positioned at the copper heat-exchanging tube bundle of housing, the tube sheet 12 of fixed copper heat exchanger tube 5, the deflection plate 7 that interval is arranged on housing and the bobbin carriage with wood closure structure (1 and 8) that lays respectively at housing both sides.On housing, have on intermediate water import 4 and intermediate water outlet 10, two bobbin carriages and have cooling water inlet 9 and coolant outlet 2.Each tubular heat exchanger is provided with 11, three tubular heat exchangers of saddle and is fixedly connected with by saddle, and copper heat-exchanging tube bundle and tube sheet adopt explosive welding.The setting of deflection plate is in order to extend shell side, fully heat exchange.For fear of intermediate water, directly wash away heat-exchanging tube bundle, intermediate water import department arranges impingement baffle 3.
As shown in Figure 4, copper heat exchanger tube 5 is inserted in tube sheet 12 holes, detonator 14 is inserted in explosive 15, each pore explosive that detonates after complete all tubesheet holes to be installed, the radial impact load that explosive charge produces welds copper heat exchanger tube 5 and tube sheet 12.
Operation principle of the present invention is:
Intermediate water is cooled via high, medium and low three tubular heat exchangers in turn, and cooling water is in turn via basic, normal, high three tubular heat exchanger heat exchange, and two kinds of fluids of shell side have been realized full countercurrent flow in heat exchanger package.
Tube sheet explosive welding basic principle: after laying explosive and detonate in the copper heat exchanger tube to be welded, copper heat exchanger tube weld tube wall can obtain powerful radial impact load in explosive charge moment, make tube wall with the collision of high speed and tube sheet, this collision pressure considerably beyond the dynamic yield strength of material itself.The interatomic cohesive energy that the jet of high velocity impact produces is aggregated in one two kinds of different metals, makes to have set up between metallic atom new balance, thereby realizes the metallurgical binding of two kinds of different metals.
The present invention adopts cylindrical shape medicine box holding medicine, for preventing that copper pipe inwall from producing blast burn, adopts the thick toilet paper of 0.6mm to make medicine box.
