Description
Technical field
The present invention relates to a kind of heating unit.Specifically, be to be used for seawater is heated so that follow-up salinity in the seawater is carried out isolating device, be applicable in the desalination treatment system of seawater, also can be used for the heating of other various liquid.
Background technology
Along with the fast development of industry and warming of weather, the shortage of Freshwater resources becomes clear day by day.Especially in some hinterland and desert area, the poorness of fresh water is particularly protruded, and has had a strong impact on development of industry and agriculture and people's quality of life.Therefore, need to seek new water source.As everyone knows, seawater is inexhaustible water resources.But, can't directly be used for industrial and agricultural production and people's life owing to contain salt in the seawater.Therefore, just need the salinity in the seawater be separated, make desalinating sea water into fresh water.And want seawater is desalinated processing, just must heat and vaporize seawater.Wherein, seawater heated still adopt traditional method, delivering to next procedure again after promptly adopting boiler that seawater is heated separates.Because the traditional heating method needs boiler, not only equipment huge, take up space manyly, and facility investment is many, manufacturing cost is high.
Summary of the invention
The problem that the present invention will solve provides a kind of preheater.This preheater, volume is little, take up space few, and facility investment is few, can reduce production costs.
For addressing the above problem, take following technical scheme:
Preheater characteristics of the present invention are to comprise cylindrical shell; This cylindrical shell is be vertical layout cylindrical; In the cylindrical shell at the contiguous tube end with in the cylindrical shell on contiguous tube top lower clapboard and upper spacer are arranged respectively, so that cylinder lumen is separated into distribution chamber, heating chamber and converges the chamber according to order from bottom to top.Be evenly equipped with through hole on upper spacer and the lower clapboard, all be connected with heat transfer tube between relative through hole between upper spacer and lower clapboard, make through heat transfer tube and converge the chamber and be communicated with distribution chamber.On the cylindrical shell top cover with tower at the bottom of on seawer outlet and sea intake are arranged respectively, this seawer outlet and sea intake respectively with converge the chamber and distribution chamber is communicated with.The heating agent outlet is arranged on the barrel of heating chamber top, on the barrel of heating chamber below heating agent import and condensation-water drain are arranged, said heating agent import, heating agent outlet and condensation-water drain all are communicated with heating chamber.
Wherein, heating agent import and heating agent the outlet be in respectively barrel on the side tube-wall.
Supporting leg is arranged around in addition, in the cylindrical shell lower end.Said supporting leg has three, and these three supporting legs are equidistant layout at circumferential direction, and their upper end is fixed on the barrel all around of cylindrical shell lower end.
Take such scheme, have the following advantages:
Can find out by such scheme; Because preheater of the present invention comprises cylindrical shell; In the cylindrical shell at the contiguous tube end with in the cylindrical shell on contiguous tube top lower clapboard and upper spacer are arranged respectively, so that cylinder lumen is separated into distribution chamber, heating chamber and converges the chamber according to order from bottom to top.Be evenly equipped with through hole on upper spacer and the lower clapboard, all be connected with heat transfer tube between relative through hole between upper spacer and lower clapboard, make through heat transfer tube and converge the chamber and be communicated with distribution chamber.On the cylindrical shell top cover with tower at the bottom of on seawer outlet and sea intake are arranged respectively, this seawer outlet and sea intake respectively with converge the chamber and distribution chamber is communicated with.The heating agent outlet is arranged on the barrel of heating chamber top, heating agent import and condensation-water drain on the barrel of heating chamber below, said heating agent import, heating agent outlet and condensation-water drain all are communicated with heating chamber.
During work, seawater through sea intake, distribution chamber, heat transfer tube with after converging the chamber, is discharged from seawer outlet successively.Meanwhile, the heating agent of warm air and so on gets into heating chamber through the heating agent import, and the heating of the seawater in pipeline and pipeline back is discharged from the heating agent outlet.Employing has just realized the heating to seawater by cylindrical shell and tube intravital upper and lower dividing plate and heat transfer tube, compare with adopting the boiler type of heating in the background technology, not only equipment volume little, take up space less, and reduced facility investment, reduced manufacturing cost.
Description of drawings
Fig. 1 is a preheater structural representation of the present invention.
Embodiment
Preheater of the present invention as shown in Figure 1 comprises cylindrical shell 4; This cylindrical shell is be vertical layout cylindrical; Be respectively arranged with lower clapboard 2 and upper spacer 8 in the cylindrical shell 4 at the contiguous tube end and in the cylindrical shell 4 on contiguous tube top; All be around lower clapboard 2 and the upper spacer 8 on sealing shape welding cylindrical shell 4 inwalls, so that cylindrical shell 4 inner chambers are separated into distribution chamber 12, heating chamber 10 and converge chamber 6 according to order from bottom to top.Be evenly equipped with through hole on upper spacer 8 and the lower clapboard 2, all be connected with heat transfer tube 9 between 2 relative through holes of upper spacer 8 and lower clapboard, make through heat transfer tube 9 and converge chamber 6 and be communicated with distribution chamber 12.Be processed with seawer outlet 7 and sea intake 13 on the end respectively with tube on cylindrical shell 4 top covers, this seawer outlet and sea intake respectively with converge chamber 6 and distribution chamber 12 and be communicated with.Be processed with heating agent outlet 5 on the barrel of heating chamber 10 tops, be processed with heating agent import 11 and condensation-water drain 3 on the barrel of heating chamber 10 belows, said heating agent import 11, heating agent outlet 5 and condensation-water drain 3 all are communicated with heating chamber 10.
