Fluid reservoir 27 is provided with in the outlet of the second channel of the 6th described heat exchanger 19.
Using method of the present utility model and the course of work are described as follows (to process a kind of technological process of weak solution):
1. open first via treatment facility P1, weak solution flows through heater 111, the primary channel of the 4th heat exchanger 13 and the primary channel (now the not raw activated vapor thermal source of system) of the 5th heat exchanger 14 in circulating pump I, valve 1 and valve 4, first to the primary channel, the first flash vessel 11 of the 3rd heat exchanger 7-9 successively, weak solution out enters the second flash vessel 15 afterwards from the 5th heat exchanger 14 and sprays, flash distillation again.Because pressure in the second flash vessel 15 is lower, weak solution under low pressure flashes off water at low temperature steam, at this moment starts steam compressor 17 and compression intensification is carried out in the suction of water at low temperature steam.Steam after intensification exports the secondary channel of press-in the 5th heat exchanger 14 by steam compressor 17, for heating flowing through its elementary weak solution, the steam again being flashed off higher temperature by the weak solution heated in flash vessel 15 is sucked by compressor 17 and again compresses intensification, so can be increased to designed pressure, temperature requirement at the steam temperature of of short duration time inner compressor 17 outlet.
2. after the first pipeline P1 normal operation input, second road treatment facility P2 devotes oneself to work: open valve 2,3,6, weak solution is made to enter the 8th heat exchanger 24 and the 9th heat exchanger 25, the weak solution in concentrated solution heating the 9th heat exchanger 25 that the bottom of the second flash vessel 15 exports.Entered the 3rd flash vessel 22 by the weak solution heated to spray, because Stress control in flash vessel 22 is in certain scope, weak solution becomes concentrated solution after flashing off water vapour.
3. after flashing off steam in flash vessel 22,3rd treatment facility P3 devotes oneself to work, opening valve 5 makes weak solution flow to the 6th heat exchanger 19, the 7th heat exchanger 20 is entered after flowing out the concentrated solution heating of concentrated solution heat exchanger 25, flowed out by from flash vessel 22(bottom in the 7th heat exchanger 20) concentrated solution heating after flow through heater 221 in flash vessel 22, enter the first flash vessel 11 after being further heated in flash vessel 22 to spray, after flashing off water vapour, become concentrated solution.Condensed water outflow in first flash vessel 11 enters the secondary channel of the second heat exchanger 8 for heating the weak solution in its primary channel; This weak solution, when flowing through the primary channel of the 3rd heat exchanger 9, is heated further by from the concentrated solution in the first flash vessel 11.Process is below with the process of the 1st article is identical above, just heated after flowing through each heat exchanger, detailed process is as follows: the weak solution flow through after the 3rd heat exchanger 9 flows through the heater 111 in the first flash vessel 11, the primary channel of the 4th heat exchanger 13 is entered after being heated by the heater 111 in the first flash vessel 11, after heating from the condensed water in the 5th heat exchanger 14, flow through the primary channel of the 5th heat exchanger 14, weak solution enters flash vessel 15 after being heated by water vapour compressor 17 high-temperature water vapor out in the 5th heat exchanger 14 and sprays, concentrated solution is become after flashing off intermediate water steam.This process moves in circles, and the weak solution making three road treatment facility P1, P2, P3 is the product that needs of simmer down to constantly, and system run all right is effective.
When needing the different weak solution of process two or three (processed chemical industry solutions), opening the liquid pump of the treatment facility on an above-mentioned corresponding road respectively, carrying out according to above-mentioned handling process.
Although the utility model MVR new equipment adds equipment investment on the basis of conventional process flow, energy-saving effect produced thus is very significant.For there being the design technology demand that multiple product need process or single product treating capacity is large simultaneously, this cover new technological flow is very rational in use, and the economic effects of energy-saving produced is very large, thus greatly reduces production cost.
The utility model can meet a thermal source can process the product that three kinds of differences concentrate requirement simultaneously, can when meet product separately evaporating pressure of different nature and temperature heat energy is fully utilized.This efficient MVR system flow can process with a thermal source solution that three kinds of differences require concentration simultaneously, and treating capacity is identical.That is the merit of three steam compressors can be made of a steam compressor, also by the amount of a steam compressor process same concentration solution three times, namely thermal source service efficiency 300% can be can improved.MVR material process pipe-line system configures three tunnel dilute solution inlet pipelines, and only enable a road as only processed same character weak solution, three tunnel treatment systems work simultaneously, can process the weak solution of three times.All enable as processed three kinds of weak solution three-way connection (pipe) lines of different nature simultaneously, three-way connection (pipe) line valve transfer is very convenient to use, and does not use activated vapor thermal source when whole system starts.
MVR is a heat pump Waste Water Treatment, the utility model just to be worked principle explanation with Application in Chemical Engineering citing, in fact any have the region of waste water can apply (except the waste water containing radioactive substance), as processed the various waste water of any industry, and desalinization.This device structure slightly adjusts the cold and heat source that can also provide refrigeration, heating while process waste water.Only do not need to start raw this advantage of steam of thermal source just can save 100 ~ 3,500,000 yuan infusion of financial resources to user.
