Abstract
The utility model provides a sea water desalination distiller, which comprises preheaters, evaporators, a spray device, a concentrated water pipe, a fresh water pipe and the like. The sea water desalination distiller is characterized in that the evaporators are rectangular, and effect evaporators are vertically arranged; each layer is provided with one preheater; the effect evaporators on the upper layer adopt nozzles or spray plates to spray, and the effect evaporators on the lower layer adopt the spray plates to spray; and concentrated sea water of the upper layer enters the effect spray spaces of the lower layer through a concentrated water J-shaped pipe.
Description
Technical field
The present invention relates to the sea water desaltination field, especially a kind of distillation sea water desalting device.
Background technology
Sea water desaltination claims sea water desalinization again, is the technology and the process of separating salt and water in the seawater.
Distillation method instant heating method is the desalination technology that adopts the earliest, is the topmost method of sea water desaltination.Distillation sea water desalting is with the seawater heating evaporation, makes vapor condensation obtain the process of fresh water again.
Low temperature multiple-effect distillation (LT-MED) be most widely used also be one of method for desalting seawater of being considered to the most energy-conservation, its principle is to allow the seawater after heating evaporate in a plurality of placed in-line vaporizers, the steam that previous evaporator evaporation is come out is as the thermal source of next vaporizer, and condensation becomes fresh water, this evaporation and condensation process repeat along each effect of a string vaporizer always, and every effect has all produced a considerable amount of distilled water.
At present, LT-MED technology mainly contains two types, a kind of is the counter-current process that comes from the Middle East, be called technology one, directly pump into several single-effect evaporators in back by pump behind the seawater preheating, dense water is being pumped into several effects in front between imitating, so repeatedly evaporation, finish the water supply that each is imitated by pump 2 to 3 effects, the seawater repeated evaporation improves concentration ratio; Another kind is the advection technology that comes from France, and seawater progressively sprays each effect respectively after the preheating, and each imitates water inlet all is former seawater, and promptly seawater only concentrates through single vaporization.
These two kinds of process characteristics and existing problems are as follows respectively:
1, technology can significantly improve concentration ratio once crossing repeated evaporation;
2, technology one is essential is equipped with 3 or more than pump between 3 effect, and seawater is repeated pressurization, has increased the sea water desaltination energy consumption;
What the first evaporator that 3, vaporization temperature is the highest in the technology one sprayed is the highest seawater of concentration, has so increased the danger of first effect fouling, also higher to material requirements;
4, technology two parallel water inlets reduce first evaporator fouling danger;
5, technology two is finished a whole set of evaporation unit water supply by an intake pump, has saved the energy consumption of pump between imitating;
6, seawater has only passed through single vaporization and has concentrated in the technology two, and concentration ratio is lower;
7, the seawater desalination evaporators in technology one and the technology two all is a cylindrical design.
The utility model content
The purpose of this utility model is to provide a kind of sea water desaltination water distilling apparatus, can improve the seawater enrichment factor, reduces the fouling danger, need not imitate a pump simultaneously, reduces the sea water desaltination energy consumption.
The technical solution of the utility model: a kind of sea water desaltination water distilling apparatus, comprise preheater, vaporizer, spray equipment, dense water pipe, fresh water pipe etc., it is characterized in that vaporizer is a rectangle, each imitates arranged vertical; Every layer is provided with a preheater; Each single-effect evaporator of upper strata adopts nozzle spray or shower plate spray, and lower floor all adopts the shower plate spray; The upper strata concentrated seawater enters each spray space of imitating of lower floor through a J-shaped pipe.
Each above-mentioned single-effect evaporator arranges that imitating number is generally the 2-4 effect, can arrange layer 2-4 or more for every layer.
It is top that each above-mentioned single-effect evaporator arranged vertical is meant that the high several effects of vaporization temperature are arranged in, and is followed successively by several effects that vaporization temperature is taken second place downwards, several effects that lowest layer vaporization temperature is minimum.
Each connecting tube of above-mentioned vaporizer all is arranged as inner tube.
Above-mentioned concentrated seawater enters lower floor with superheat state, and each is imitated.
The concrete mode of operation of a kind of sea water desaltination water distilling apparatus that the utility model relates to comprises following steps:
(1) seawater enters the vertically arranged vaporizer the superiors after by the preheater preheating, and sprays by nozzle or spray version in the vaporizer of upper strata;
(2) the overheated concentrated seawater of process Evaporation in the evaporator room relies on gravity to enter each spray space of imitating of lower floor by the J-shaped pipe, sprays the heat transfer tube surface by shower plate;
(3) after overheated concentrated seawater passes through Evaporation once more, repeat the process of (2), converge the dense water tank of last evaporator until concentrated seawater and discharge;
(4) each is imitated the fresh water that produces and enters each fresh-water tank of imitating of lower floor by relying on gravity by the J-shaped pipe, converges to the last evaporator fresh-water tank at last and discharges.
Superiority of the present utility model is:
1, concentrated seawater enters several effects of lower floor by gravity, reduces the sea water desaltination energy consumption;
2, guarantee that the highest a few effect water inlets of vaporization temperature are former seawater, the fouling risk reduces;
3, each effect water inlet of other except that top was hot sea water, and vaporization efficiency improves;
4, seawater obtains repeated evaporation and concentrates the raising concentration ratio;
5, decoration form is more flexible, arranges that imitating number is generally the 2-4 effect, can arrange layer 2-4 or more for every layer;
6, each connecting tube of each single-effect evaporator all is arranged as inner tube, and outward appearance is more clean and tidy;
7, repair and maintenance is convenient.
