Background technology
Distilled water refers to the pure water prepared with distillating method.Once and repeatedly distilled water can be divided.Water is through single flash, and nonvolatile component is residual to be removed in a reservoir, and the component of volatilization enters in the initial fraction of distilled water, usually only collects the middle portion of cut, accounts for 60%.Obtain purer water, alkaline permanganate solution can be added in first water, removing organism and carbonic acid gas; Add nonvolatile acid, make ammonia become nonvolatile ammonium salt.Owing to containing the component that energy is water-soluble on a small quantity in glass, when therefore carrying out secondary or repeatedly distill, use quartz still ware, just can obtain very pure water, gained pure water should be kept in quartz or silvery container.The water of occurring in nature is impure, usually containing multiple salt such as calcium, magnesium, iron, also containing organism, microorganism, dissolved gases (as carbonic acid gas) and suspended substance etc.Non-volatile composition wherein can be removed with distillating method.By distillation method, and coordinate following measures, the distilled water that quality is higher can be obtained.
The flow process of multi-effect water distillator is as follows: raw water is heated by industrial steam at an effect preheater, then distribution enters evaporator with central downcomer equably, forms the current of film like in evaporator with central downcomer; These current, because thin so evaporated very soon, produce steam; Be not transported to next effect, as the raw water of secondary single-effect evaporator by the raw water evaporated; By the raw water evaporated, continue to screw on liter in vaporizer mid-game, through condenser device place, middle and upper part, enter pure vapour line, as the thermal source of secondary effect; Steam condenses into distilled water after secondary effect is absorbed heat; Each effect process similarly, collect by each distilled water of effect and the secondary steam of the end effect device that is condensed, and through and water coolant, raw water heat exchange, cooling becomes distilled water; Through the on-line checkingi of specific conductivity, qualified distilled water exports as water for injection, and underproof distilled water will be discharged.
Existing multi-effect water distillator adopts high-temperature operation, guarantees stably manufactured pyrogen-free water for injection.But there is the shortcoming wasted energy in high-temperature operation.

Nomenclature in figure: temperature sensor 1, pressure transmitter 2, the first control valve 3, add water pipeline 4, spray thrower 5, evaporator with central downcomer 6, heating gas inlet 6-1, pneumatic outlet 6-2, the 3rd control valve 6-3, high pressure tank body 7, condenser 8, non-distilled water escape route 9, controller 10, the second control valve 11.
Embodiment
By best embodiment, the utility model is described in detail below.
As shown in Figure 1-2, low temperature multiple-effect distillation water machine, comprises some distilled water generators be arranged side by side, and is high pressure tank body 7 outside each distilled water generator, be provided with spray thrower 5 and evaporator with central downcomer 6 in high pressure tank body 7, spray thrower 5 is arranged at directly over evaporator with central downcomer 6; On the left of evaporator with central downcomer 6, top and lower right-hand side have heating gas inlet 6-1 and pneumatic outlet 6-2 respectively, heating gas inlet 6-1 are provided with the 3rd control valve 6-3; Spray thrower 5 connects the pipeline 4 that adds water, and high pressure tank body 7 outlet at bottom is provided with the second control valve 11, second control valve and connects non-distilled water escape route 9; The vapor outlet port on high pressure tank body 7 top is provided with the first control valve 3, first control valve and connects condenser 8 by pipeline; Also be provided with temperature sensor 1 and pressure transmitter 2 in high pressure tank body 7, the input terminus of temperature sensor 1 and pressure transmitter 2 connection control device 10, the output terminal of controller 10 connects the first control valve 3, second control valve 11 and the 3rd control valve 6-3 respectively.
The evaporator with central downcomer that the utility model adopts is existing conventional setting, and it belongs to the vaporizer of natural circulation type all.Its heating chamber is 25mm--75mm by caliber, and length is the upright tube bank composition of 1m--2m (ratio of major diameter is about 20-40), at the pipe that tube bank central authorities installation one is thicker.During operation, in tube bank, the heating surface area of unit volume solution is greater than in extra heavy pipe, namely the former is heated, solution boils is many, therefore the solution vapor content in tubule is many, causes the little of solution in density ratio extra heavy pipe, the cyclic motion that this density difference impels solution to do to decline along extra heavy pipe and rises along tubule, therefore extra heavy pipe is also called downtake except being called central circulating tube, tubule is called heating tube or boiling tube.In order to impel solution to have good circulation, during design, get the 40%-100% that central circulating tube sectional area is heating tube bundle total sectional area.
This evaporator with central downcomer develops from horizontal heating chamber and coil tube heating room vaporizer.For these old-fashioned vaporizers, it has the advantages such as solution circulated is good, rate of heat transfer is fast, and simultaneously due to compact construction, easily manufactured, application is very extensive, has the title of " standard pan ".The heat transfer area of this vaporizer can up to hundreds of square metres, and heat transfer coefficient is about 600w/ (m. DEG C)--3000w/ (m. DEG C).
Last it is noted that obviously, above-described embodiment is only for the utility model example is clearly described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of amplifying out or variation be still among protection domain of the present utility model.
