Abstract
The invention discloses a normal-temperature whole-phase-change seawater desalination device. The horizontal single-tank seawater desalination device comprises an evaporation condenser, a condensed seawater tank, a fresh water tank, a vacuum pump, a seawater supplementing tank, a fresh water pump, a condensed seawater pump, a seawater pump, a first seawater preheating tank, a second seawater preheating tank, a third seawater preheating tank, and a seawater heating tank. The seawater desalination device only has one seawater pump for providing power to seawater spraying. Before the supplemented seawater enters the pump, the seawater should be pre-heated for the first time. Before the seawater is sprayed, the seawater is circulated, preheated for the first time, heated, and preheated again. In one evaporation condenser, there are five spraying areas with five different temperatures, the temperature difference between the highest temperature and the lowest temperature is around 40 DEG C, due to the temperature difference, the pressure difference between two ends of the evaporation pipe is large, thus the flowing speed of steam in the evaporation pipe is accelerated, the generated steam in the five spraying areas is not cooled by the cooling water in or out of the system, and the phase-change potential heat is utilized during the whole seawater distillation process to carry out heat exchange. The provided device largely reduces the manufacturing cost and operation cost.
Description
Technical field
The invention belongs to a kind of Hai water Danization Installed to put, use distillation method specifically, make sewage purification, seawater or saline-alkali water desalination Installed are put.
Background technology
On 01 13rd, 2014 number of patent applications are the innovation and creation technical scheme of 201410012474.8, the independent claim of this application, disclose the scheme that full phase transformation distillation sea water desaltination Installed puts, the program needs hot sea water pump, circulating seawer pump, charging sea-water pump three Ge pump cooperation, there is provided the power of seawater spraying, each pump also needs the parts such as supporting valve.This claim also discloses one without hot sea water pump, without circulating seawer pump, only with the design of a charging sea-water pump, do not have Give to go out specific embodiments.
Invention Inner holds
One that the invention discloses that full phase transformation distillation sea water desaltination Installed puts new scheme is namely the Improvement and perfection of 201410012474.8 technical schemes to number of patent application.This new departure, only with a sea-water pump, this pump just has effect of above-mentioned three pumps, and therefore, manufacturing cost operation cost significantly reduces.
The full phase transformation sea water desalinating plant of normal temperature of the present invention, has horizontal pair of tank body and horizontal single tank body and multiple-tank body three kinds of structure formations, and two tank body is connect by two single tank bodies to form, and multiple-tank body is the molectron be formed in parallel by more than two single tank bodies or two tank body.Parallel method is identical with former parallel method, and the present invention no longer describes, and the present invention program only has content and the picture of horizontal single tank body.
Sea-water pump in the normal temperature of the present invention full phase transformation sea water desalinating plant program has four functions: one can supplement new seawater, two can make seawater circulation, three can heat pump total seawater 1/5th, and four can carry out preheating again to pump total seawater 3/5ths.
The full phase transformation sea water desalinating plant of normal temperature of the present invention, according to the height of the highest spray temperature, determine the number spraying interval quantity, spray interval range is 3-6, if spray beautiful jade top temperature is at about 30-40 DEG C, the rarest three sprays are interval, if spray top temperature is at about 60 DEG C, six need only be had at most to spray interval.Be any temperature of 30-60 DEG C in winter-spring season to the top temperature of heating of seawater, the spray top temperature of seawater is any temperature of 30-60 DEG C, and the spray temperature that seawater is minimum is about 10 DEG C.Be 40-60 DEG C in summer and autumn to the top temperature of heating of seawater, the spray top temperature of seawater is that spray temperature that any temperature seawater of 40-60 DEG C is minimum is about 20 DEG C (the minimum spray temperature of low-temperature multi-effect seawater desalination device is 40 DEG C.)。It is interval that vaporizer in the program is provided with five sprays, and each interval, by temperature order arrangement from high to low, when top temperature is 60 DEG C, just has 60 DEG C, 50 DEG C, 40 DEG C, 30 DEG C, 20 DEG C five to spray interval.Between the highest spray temperature and minimum spray temperature, the temperature difference is 40 DEG C, and this temperature difference makes two ends pressure reduction in the pipe of vaporizer be 10,007 kPas.Low-temperature multi-effect seawater desalination device, the vapour pressure before entering in every single-effect evaporator pipe is higher than the vapour pressure in pipe about 2 kPas.Because the pressure reduction of the program is more much larger than low-temperature multi-effect, therefore make steam flow speed fast, sea water desaltination efficiency will be higher.
The present invention program is water coolant without the seawater outside system, need not intrasystem seawater be also water coolant.In other words: the steam produced after top temperature seawater spraying in vaporizer, without cooling water condensation, the steam produced after minimum temperature seawater spraying, also without cooling water condensation, all processes of distillation is all the latent heat utilizing phase transformation to produce, and carries out thermal exchange.Be called the full phase transformation sea water desaltination of normal temperature, its device is called the full phase transformation sea water desalinating plant of normal temperature.Therefore, the remarkable overflow of heat energy power consumption is low: heat energy consumption only has, and water generation ratio is 1/7th of the low-temperature multi-effect seawater desalination device of 10; Power consumption only has, water generation ratio be the low-temperature multi-effect seawater desalination device of 10 two/-(or 1/3rd).It is low that operation cost takes remarkable overflow, when the price of coal is Renminbi per ton 500 yuan.The cost of every cubic metre of desalination water is Renminbi 2.5-3 unit.The subject matter of the invention described above and goal of the invention are achieved by following proposal.
