Abstract
The invention discloses a semi-automatic production method and equipment for preparing ice and desalinating seawater by natural energy resources. The equipment comprises a plurality of terrace-shapedicing ponds arranged in a vertical and horizontal manner, and is characterized in that seawater is poured into the icing ponds at the temperature below 0 DEG C, unfrozen water at the bottom of the icing ponds is discharged after the seawater ices to 1-2cm, and the sea ice is smashed to slump into the bottom of the ponds; an electric lifting gate of each icing pond is opened, the smashed sea ice slides down along the sloping surface of the bottom of the pond, and falls into a container after impacting an ice blocking wall; a drainage valve at the lower part of the container is opened, the sea ice melts and ices repeatedly along with the temperature difference between day and night, and salted ice water is discharged; the drainage valve is closed when the salinity of the discharged salted ice water is detected to be less than 1 per mill, and the ice in the container melts into fresh water by integral bask in natural state. The invention utilizes gravity to lead the ice to smash automatically to slide into a vehicle through a sloping surface, thus heavy physical labor in the link that ice is collected and transported into the icing pond is omitted in the prior art.
Description
Affiliated technical field
The present invention relates to a kind of production method and equipment of sea water desaltination, especially relate to a kind of semi-automatic production method and equipment that utilizes the natural energy resources ice making to desalinize seawater.
Background technology
Current, the indirect desalination process of sea water desaltination (mainly being the method that sea ice is made fresh water) is paid close attention to for people gradually.Wherein, the method for utilizing natural energy resources to make sea ice and sea ice making fresh water meets requirement on environmental protection most, is worthy to be popularized most.But never utilize aforesaid method to carry out large-scale industrialized production so far, and large-scale industrialized production must there be the equipment of corresponding mechanize or automatization to cooperate, but occur relevant research report as yet so far.
As patent CN1686839A (utilizing the method for natural cooling source desalting bitter through ice making), its principal feature is to be full of seawater or to take from subterranean brackish water in nature or man-made pond(pool), utilized when winter, temperature reached below 0 ℃ and freeze naturally, adopting ice then stores, place the bottom that the ice-melt pond of water port is set the ice cube of tentatively desalination, the salty frozen water that discharging is at first dissolved keeps the residue desalination water.
Patent CN1699196A (seawater desalting device with temperature control and frost thawing functions) and for example, its principal feature is that the velocity ratio of desalination wants fast under state of nature, its with sea ice place can controlled temperature thawing room in, the salty frozen water that discharging is at first dissolved keeps remaining desalination water.
Above-mentioned two patents also do not relate to mechanize or the technology of icing and transporting the ice aspect is adopted in automatization.
Need a large amount of heavy physical labours if adopt the operation of ice, fortune ice, so this production can only be workshop-based production, is difficult to the development prospect of large-scale industrialized production.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this invention is to provide a kind of semi-automatic production unit and production method of utilizing the natural energy resources ice making to desalinize seawater, make every effort in the large-scale industrialized production that ice making desalinizes seawater, reduce dependence to manpower.
Semi-automatic production unit of the present invention is achieved in that its icing pond 1 by a plurality of likeness in form terraced fields of arranging in length and breadth constitutes, icing pond overlook into opening towards tubaeform 2 of lower, freeze the bottom, pond be to lower tilt domatic 3, the positive cross section in icing pond is up-small and down-big tubaeform 4; Described opening is provided with electric up-down gate 21 towards the flaring opening part of lower, the bottom in icing pond is provided with automatically controlled water valve 31 of draining and water shoot 32, top, icing pond is provided with into automatically controlled water valve 11 of water and water inlet pipe 12, and the wherein high-order pond that freezes is communicated with by water shoot 32 with the icing pond of the low level of adjacent row; The icing pond of lowest part is communicated with by water shoot 32 with discharge culvert 9 under being located at it; The below, icing pond of lowest part is provided with a passage 5, and many movably freight containers 7 are set in this passage, and the top of this passage is provided with retaining ice wall 6 together.
The most shallow place in described icing pond is 40cm, and the obliquity of bottom domatic 3 is 7 °-30 °, and opening is 7 °-10 ° towards tubaeform 2 monolateral gradients of lower, and tubaeform 4 up-small and down-big monolateral gradient of positive cross section is 7 °-15 °.
Semi-automatic production method of the present invention is achieved in that
Be lower than time below 0 ℃ at temperature, pour into seawater in icing pond 1 of the present invention, when treating seawater icing to 1-2cm, discharge first row seawater that the bottom, pond freezes that freezes, this seawater enters the concentraing pond raw material of evaporating brine in addition; Sea ice 8 fragmentations, slump is at the bottom of the pond; Open the freeze electric up-down gate 21 in pond of first row then, broken sea ice domatic 3 sliding at the bottom of the pond, behind the bump retaining ice wall 6, fall in freight container 7:
Close icing pond electric up-down gate 21 of first row and the automatically controlled water valve 31 of draining, open the automatically controlled water valve 31 of draining of bottom, the icing pond of adjacent secondary series, the seawater that does not freeze at the bottom of its pond flows into the first adjacent row and is in the icing pond of low level, part seawater as the icing usefulness of next round, open the automatically controlled water valve 11 of water inlet in the icing pond of first row then, till mending the seawater in the first icing pond that is listed as completely, be allowed to condition at then in the natural cold air and freeze; Simultaneously, after the water emptying in secondary series freezes the pond, open its electric up-down gate 21, broken icing skidding off fallen in freight container 7;
After the sea ice in the pond of successively last row being frozen packed into the container in 7, if arrange properly, the ice that first row freeze in the pond had been formed 1-2cm thickness, can gather again, so can gather sea ice again and again.
Use transportation means, the freight container of filling sea ice is transported to the distribution centre disperse to place, on freight container 7,, open the water discharging valve 71 of freight container bottom, enter the ice-melt operation with the plastics film sealing; Sea ice is along with round the clock the temperature difference, and salty frozen water is discharged in thawing repeatedly; After the salinity of the salty frozen water that detects discharge is less than 1 ‰, close water discharging valve 71, stay the vexed solarization of ice under state of nature in the freight container 7, melt and turn to fresh water.Also freight container 7 can be piled up, form ice cell, for the ice industry provides the ice source.
The invention has the beneficial effects as follows:
1, utilize gravity, make freeze broken voluntarily, through the domatic transportation means that slips into, the sea of having saved prior art adopt ice and
Fortune is iced the heavy physical labour to the link of ice-melt pond.
2, except that the logistics worker, the operator of an order of classes or grades at school only two to three people just can make the huge ice making workshop that desalinizes seawater get into smooth.
3, freight container can move freely and make up as the ice-melt pond.Placed apartly be convenient to ice-melt; Concentrated stacking can be used as ice cell, for the ice industry provides the ice source.
4, the desalinize seawater freight container in idle time of workshop of ice making can be made the shipping purposes in addition.
