Abstract
An out plate type evaporator includes a carburetor and a heat exchanger. The heat exchanger adopting an out plate type heat exchanger and is arranged in the outside part of the carburetor and is connected with the carburetor through a feed pipe, a discharge pipe and a recycle pump arranged on the discharge pipe. The heat exchange sheets of the heat exchanger are assembled by multiple stainless steel corrugated plates through heat resistant seal cushion. When operating, flash evaporation is generated when the feed liquid enters into carburetor under enforced driving of a high flow recycle pump and the evaporation efficiency has been improved greatly. The utility model can avoid scale formation and plugging as well as be convenient for unpicking and washing, maintenance, assembly and multiplexing use.
Description
Technical field
The utility model relates to a kind of no solid phase of industrial circles such as chemical industry, papermaking, light industry, medicine, environmental protection, low concentration evaporation equipment of low thick liquid of being applicable to.Particularly relate to a kind of low concentration evaporation concentration equipment that is used to handle black liquid.
Background technology
At present, in paper industry, the pollution of black liquid becomes the major obstacle of industry development, and for this reason, people have developed the various technology and equipments that are used to handle black liquid.For example be called in the utility model patent of " movable free outflow falling-film plate type evaporimeter " for CN2155262Y, name at Granted publication number, disclose a kind of evaporimeter that can reclaim black liquid, in evaporation equipment commonly used, also have tubular evaparator, be used for low dope body is carried out evaporation and concentration.But existing evaporimeter or evaporation efficiency are not high, or are easy to fouling, result in blockage.In addition, existing evaporation equipment is not easy dismounting, cleans, keeps in repair and installs.
Summary of the invention
The utility model is exactly in order to solve the technical problem that evaporation efficiency in the existing evaporation equipment is not high, not quick detachable, clean, a kind of outer board-like evaporimeter is provided, adopt outer board-like heat exchanger, and employing stainless steel wave card is as the heat exchanging fin of heat exchanger, thereby improved evaporation efficiency, energy savings.
The utility model is achieved in that a kind of outer board-like evaporimeter, comprise vaporizer and heat exchanger, wherein said heat exchanger adopts outer board-like heat exchanger, be arranged on described vaporizer outside, and be connected with described vaporizer by feed pipe, discharge nozzle and the circulating pump that is installed on the discharge nozzle.
The utility model can realize so further that also promptly the heat exchanging fin of described heat exchanger is combined by the temperature resistant encapsulation rubber cushion by multi-disc stainless steel corrugated cardboard sheet, and the thickness of stainless steel corrugated cardboard sheet is 0.7 millimeter or lower.
Because outer board-like evaporimeter described in the utility model is arranged on the vaporizer outside with heat exchanger, when feed liquid enters vaporizer under the pressure of big flow circulating pump drives, produce flash distillation, improved evaporation efficiency greatly.And, because this evaporimeter moves, avoided fouling and obstruction under the forced circulation of circulating pump, heat exchanger is arranged on the outside of vaporizer, also be convenient to unpick and wash, keep in repair and assemble multiplexing.
Description of drawings
Fig. 1 is the schematic diagram of outer board-like evaporimeter described in the utility model.
The specific embodiment
Below in conjunction with accompanying drawing outer board-like evaporimeter described in the utility model is described in further detail.
With reference to accompanying drawing, this evaporimeter mainly comprises a vaporizer 1 and a heat exchanger 2, wherein, the bottom of vaporizer 1 is provided with a liquid inlet and outlet 7, during evaporation, wanting processed black liquor feed liquid to import from this liquid inlet and outlet, carry out evaporation process after closing, after the evaporation certain hour, open this liquid inlet and outlet 7 again, the defective material after the evaporation is discharged.Simultaneously, also be respectively equipped with not condensing outlet 9 of a secondary vapor outlet 8 and on the top of vaporizer 1, be used for indirect steam and do not have the gas discharge of condensation; In vaporizer 1 upper inside, be provided with a froth breaking net 10 and a deflection plate 11, wherein, froth breaking net 10 can fall the foamed filter in the steam that will discharge, and deflection plate 11 is used to make the fluid of rising to return; Can also one thermometer boss be set at vaporizer 1 sidepiece, be used for laying temperature meter within it, vaporizer 1 temperature inside is detected.
Heat exchanger 2 adopts outer board-like heat exchanger, the outer surface that is somebody's turn to do outer board-like heat exchanger has 4 to advance, outlet, it is respectively steam inlet 5, steam (vapor) outlet 6, liquor inlet 14, material liquid outlet 15, portion is provided with two circuits within it, one the tunnel for to advance with steam, going out can 5, the 6 Steam Heating pipelines that connect, one the tunnel is to advance with feed liquid, outlet 14, the 15 heated feed liquid circulation pipelines that connect, heat exchanging fin 4 is combined by the temperature resistant encapsulation rubber cushion by multi-disc stainless steel corrugated cardboard sheet, preferred 0.7 millimeter or lower of the thickness of these stainless steel corrugated cardboard sheets can improve heat exchange efficiency like this.
Between vaporizer 1 and heat exchanger 2, connect by circulating line, wherein, the material liquid outlet 15 of heat exchanger 2 is connected with the liquor inlet 16 of vaporizer 1 by feed pipe 13, and the liquor inlet 14 of heat exchanger 2 is connected with the material liquid outlet 17 of vaporizer 1 by discharge nozzle 18, and on the discharge nozzle 18 between material liquid outlet 17 and the liquor inlet 14 circulating pump 3 is installed.
During work, the black liquid that needs evaporation process advancing by vaporizer 1, liquid outlet 7 these vaporizers of input, afterwards, start circulating pump 3, make the black liquor that adds in the vaporizer 1 at vaporizer 1, pipeline 13, carry out forced circulation between heat exchanger 2 and the circulating pump 3, simultaneously, by the steam inlet 4 heat exchanger 2 input heating steams of jet chimney from heat exchanger 2, thereby black liquor is heated, and heated black liquor further is recycled to vaporizer 1, the fraction that the black liquor mid-boiling point is low under the forced circulation of circulating pump, as moisture, will evaporate, discharge, realize the purpose of evaporation thus by the froth breaking net 10 and the steam (vapor) outlet on vaporizer 1 top.
Because outer board-like evaporimeter described in the utility model has adopted large volume vaporizer 1, and heat exchanger 2 is arranged on vaporizer 1 outside, when feed liquid enters vaporizer 1 under the pressure of big flow circulating pump 3 drives, produce flash distillation, improved evaporation efficiency greatly.And, owing to adopted the good heat exchanger of forming by the Thin Stainless Steel corrugated cardboard sheet of heat exchange property, further improved evaporation efficiency, can make the coefficient of heat transfer reach 7500W/m
2. ℃.
This evaporimeter is particularly suitable for being used to assemble the low dense evaporation of black liquor, in the actual motion, can with the use that combines of various vapo(u)rization systems, also can be used for single-action, economic benefits and social benefits or multiple-effect and vacuum, negative pressure evaporation.Therefore can be widely used in the low concentration evaporation equipment of the no solid phase of industrial circles such as chemical industry, papermaking, light industry, medicine, environmental protection, low thick liquid.
