Embodiment
Below in conjunction with accompanying drawing the utility model is carried out concrete description, as shown in Figure 2, the utility model comprises shell and tube heat exchanger 1, gas-liquid separator 2, vaporizer 3 and preheating tube 4.Described shell and tube heat exchanger 1 comprises heat transfer tube 11, upper tubesheet 12, lower tubesheet 13, heat exchanger shell 14 and upper cover 15, heat exchanger shell 14 is a cylinder-like structure, its upper/lower terminal is by upper tubesheet 12 and lower tubesheet 13 sealings, be provided with tens of or up to a hundred heat transfer tube 11 between described upper tubesheet 12 and the lower tubesheet 13, top is provided with the bobbin carriage of protrusion, and a side of bobbin carriage is provided with heating steam import 141; Upper cover 15 is the spill lid, and both sides are connected by the upper tubesheet 12 of web member with heat exchanger shell 14 upper ends, and this web member can be flange, also can be bolt or nut, and its upper end is provided with for raw water import 151.The outside of described shell and tube heat exchanger 1 is provided with vaporizer 3, and this vaporizer 3 is the hollow cylinder of bottom sealing, upper end open, and its upper end is connected with the bobbin carriage part lower end that heat exchanger shell 14 protrudes; Because the shell of vaporizer 3 places the outside of heat exchanger shell 14, after raw water heats through tubular heat exchange 1 like this, carry out flash distillation and have the space with separating.
Outside surface at heat exchanger shell 14 is equipped with gas-liquid separator 2.Gas-liquid separator 2 is made up of four groups of spiral plates, every group of circumferential direction interval 90 degree, rotation is installed on the shell 14 of interchanger 1, its effect is to make the secondary steam of evaporation generation after the gravity settling separation of process one-level, import spiral plate in the uphill process and force rotation, make secondary steam produce high speed centrifugation power, on the shell wall that the water droplet carried secretly in the secondary steam and mist are thrown to vaporizer, automatically flow into the lower liquid chamber, reach the effect of vapor-liquid separation.
In heat transfer tube 11 gaps of shell and tube heat exchanger 1 preheating tube 4 is installed, this preheating tube 4 is the tubular structure of U type, middle no splicing welding joint, its import 41 and export 42 and be installed on the heat exchanger shell 14 respectively.Play the effect of preheating material water; Because this preheating tube 4 is installed in the distillation tower, can reduce calorific loss.
Lower tubesheet 13 is provided with condensate outlet pipe 5, and passes the lower end of the housing of vaporizer 3.The upper side of vaporizer 3 is provided with pure vapour outlet 31, and the bottom is provided with condensed water outlet 32, and lower side is provided with visor 6, can observe the liquid-vapor mixture situation in the vaporizer.
During use, the raw water of this distillation tower is a purified water, and raw water flows out from preheating tube outlet 42 after being heated steam preheating in preheating tube import 41 flows into built-in U type preheating tube 4.
From the distillation tower top, the raw water import 151 of the upper cover 15 of interchanger 1 enters the tube side of tubular heat exchange 1 the raw water of process preheating.Enter then in the every heat transfer tube 11, become film like to flow downward along its tube wall.Heating steam this moment enters the shell side of shell and tube heat exchanger 1 from steam inlet 141, raw water in every heat transfer tube 11 is under the heat effect of heating steam, the rapid falling film evaporation of inwall along heat transfer tube 11, the secondary steam that evaporation produces and the mixture of water, enter the bottom evaporator room of vaporizer 3 downwards after, since the spatial sudden enlargement and sharply flash distillation be a large amount of secondary steams, after this secondary steam process one-level gravity settling separation, naturally rise with fast speeds, after running into the centrifugal gas-liquid separator 2 of spiral plate, be imported into the rotation of spiral plate generation of forced, because gas velocity is higher, high speed centrifugal force is thrown on the outer casing inner wall of vaporizer 3 the water droplet mist of carrying secretly in the secondary steam, relies on deadweight to flow to the bottom of vaporizer 3.Flow out through the pure vapour outlet 31 of the pure steam of secondary after the vapor-liquid separation,, be product-water for injection that we need through after the other condenser condenses aftertreatment from distillation tower.The spiral fluid removing system of this distillation tower can reliably be removed the bacterial endotoxin in the raw water, reaches " the requirement of " water for injection " in the Chinese pharmacopoeia 2000 editions fully.The last feed water that is not evaporated of coming out from the distillation tower tube side is because contain accumulative impurity in the still-process, so discharge from the condensed water outlet 32 of distillation tower.From the heating steam water of condensation that the distillation shell side comes out, discharge from the condensating water outlet tube 5 of vaporizer 3 bottoms.
