The equipment preparing concentrate disclosed by the invention comprises decompression process, condensation process, stores and flow through journey, drainage procedure, sampling process.

Decompression process: close the first switch 25, the 4th switch 22 and the 6th switch, opens second switch 24, the 3rd switch 23, the 5th switch, the 7th switch, the 8th switch and the 9th switch.Open decompressing unit 4, make the gas in boiler enter decompressing unit 4 by the 5th switch, second switch 24, the 3rd switch 23, the 9th switch successively, from but air pressure in boiler reduce.

Condensation process: open cooling unit 3, the cooling fluid of cooling unit 3 is circulated by the 7th switch, apical ring, base ring and the 8th switch successively, makes the temperature of boiler top cover lower than the temperature of vapours in boiler by cooling fluid.

Open the heating unit 12 in boiler, the temperature of liquid to be concentrated in boiler is improved, because low pressure in boiler makes the boiling point of the moisture in solution to be concentrated also reduce, so make the water in solution to be concentrated seethe with excitement at a lower temperature, and then produce the water vapour of heat, the water vapour of heat is encountered the rear condensation of strip convergence bar 1103 of boiler upper cover 11 relative low temperature and is gathered into water droplet, under the synergy of spill proof edge 1103d and water drops surface tension force, water droplet converges the first arc surface 1103b of bar 1103 or the second arc surface 1103c along strip and is slipped to and confluxes in chamber, conflux to summarize in chamber and converge from strip the water that bar 1103 landing gets off.By condensation process, the moisture in the solution to be concentrated in boiler is constantly transferred to and confluxes in chamber, and then moisture in solution to be concentrated is reduced.

Store and flow through journey: after the water level confluxed in chamber exceedes the inner spout of output channel 1105, the water confluxed in chamber is discharged to by output channel 1105 and stores in stream unit 2, successively by the 5th switch, second switch 24, store to flow through in journey and there will be following three kinds of situations: 1. the air pressure in boiler is greater than the air pressure stored in stream unit 2,2. the air pressure in boiler equals to store the air pressure in stream unit 2, and the air pressure 3. in boiler is lower than the air pressure stored in stream unit 2.

During the situation 1 of being in, the water confluxed in chamber stores stream unit 2 from being pressed under the influence of air pressure; During the situation 2 of being in, because chamber of confluxing is higher than storing stream unit 2, so the water confluxed in chamber flows under gravity store stream unit 2; During the situation 3 of being in, open decompressing unit 4, the air pressure stored in stream unit 2 is reduced, and lower than the air pressure in boiler, makes situation 3 become situation 1 or 2; Store stream unit 2 by above three kinds of mode retainings.

Due to heating unit 12 continuous heating in boiler, so the temperature in boiler is higher than the temperature stored in stream unit 2, namely cause the air pressure in boiler higher than the air pressure stored in stream unit 2, therefore heating can impel the appearance of situation 1.After the concentrate in boiler reaches predetermined concentration, heating unit 12 stops heating, air pressure in boiler declines, in order to avoid occurring that air pressure in boiler is lower than the air pressure stored in stream unit 2, decompressing unit 4 is needed to start, making to store air pressure in stream unit 2 lower than the air pressure in boiler by decompressing unit 4, entering to store stream unit 2 by remaining the condensed hydraulic pressure of water vapour in boiler.Because the water level confluxed in chamber is higher than output channel 1105 inner spout, so the water vapour in boiler can not directly enter store stream unit 2, thus reduce the harmful effect of water vapour to decompressing unit 4, inner spout due to second pipe 29 is positioned at the bottom place near cylindrical shell 21, and the inner spout of the 3rd pipeline 28 is near the top place of cylindrical shell 21, so when decompressing unit 4 works, avoid water and be immediately inhaled into the 3rd pipeline 28 after second pipe 29 is forced out, the top water that can reduce in cylindrical shell 21 that the inner spout of the 3rd pipeline 28 is arranged in cylindrical shell 21 enters the risk of the 3rd pipeline 28.

Drainage procedure: after the water level mark pipe 26 display water level stored in stream unit 2 reaches predetermined value, first close second switch 24, because second switch 24 and the 3rd switch 23 are by coupling block 20 synchronous interaction, so, while closing second switch 24, the 3rd switch 23 is also closed, after this, the water of condensation in boiler is by the chamber temporary reservoir that confluxes, after second switch 24 and the 3rd switch 23 are closed, store stream unit 2 to keep apart with boiler, open the 4th switch 22, make to store the air pressure flowed in unit 2 equal with extraneous atmospheric pressure, after air pressure balance, open the first switch 25, due to the effect of gravity, the water stored in stream unit 2 flows out from the first switch 25, realize the draining storing stream unit 2.After storing the water in stream unit 2 and be drained, first close the first switch 25 and the 4th switch 22, make to store stream unit 2 and isolated from atmosphere, open second switch 24 again, 3rd switch 23 is also unlocked simultaneously, due to store stream unit 2 in air pressure higher than the air pressure in boiler, so the moment that second switch 24 and the 3rd switch 23 are unlocked, water in pipeline will be pushed back in boiler, due to the cushioning effect in chamber of confluxing, water is rested on and confluxes in chamber, instead of directly enter in concentrate, after the air pressure stored in stream unit 2 and the air pressure balance in boiler, the condensed water of buffer memory in chamber that confluxes flows under gravity and stores stream unit 2, in order to maintain the environment under low pressure in boiler, need to open decompressing unit 4, the air pressure in boiler is made to maintain predetermined value, decompressing unit 4 open after can accelerate the water confluxed in chamber enter store stream unit 2.

Sampling process: with reference to Figure 21,22,23, sample by the concentrate in sampling unit 14 pairs of boilers in concentration process, and Concentration Testing is carried out to sampling.Before sampling, in order to improve accuracy in detection, first by handle 1406 quick rotation, as shown in figure 18, effect by centrifugal force makes the concentrate remained in thieff hatch 1404 be thrown out of, then by the direction signs on handle 1406, make thief hole upward, concentrate enters thieff hatch 1404, pull out motion bar 1403 afterwards to pull-out location, detect the concentrate in thieff hatch 1404 by detecting pen, or rotate motion bar 1403, make thieff hatch 1404 down, the concentrate in thieff hatch 1404 instills in vessel under gravity.After sampling, motion bar 1403 is pushed back to insertion position.

After concentrate in boiler reaches predetermined concentration, first close heating unit 12, decompressing unit 4, the 5th switch, open the 6th switch again, extraneous gas enters boiler internal by admission line 1108, makes the air pressure in boiler and ambient atmosphere pressure balanced, air pressure in boiler raises than time concentrated, the boiling point of the water in concentrate also increases, because heating unit 12 is closed, so the water in concentrate stops boiling, concentrate no longer loses moisture, and namely concentrate keeps existing concentration.Open discharging opening 16, the concentrate prepared is flowed out by discharging opening 16, after concentrate is drained, close discharging opening 16, open charging aperture 15, make liquid to be concentrated enter boiler by charging aperture 15, after liquid to be concentrated reaches scheduled volume, close charging aperture 15 and the 6th switch, boiler and ambient atmosphere are isolated, enters next concentration flow path.

Obviously, can solution to be concentrated be inputted at boiler or while exporting concentrate, the water stored in stream unit 2 be discharged.Detailed process is: first close the 9th switch, open the 6th switch, due to draught head, the water confluxed in chamber is pressed into and stores stream unit 2, until boiler, store stream both unit 2 in air pressure and atmospheric pressure balance after, the water confluxed in chamber flows under gravity and stores stream unit 2, opens the first switch 25 simultaneously, and the water stored in stream unit 2 is discharged.
