Abstract
The invention discloses a climbing film type evaporator which comprises a heating chamber and a separating chamber, wherein the heating chamber is connected with the separating chamber by virtue of an upper circulating pipe, a demister is arranged in the separating chamber, a secondary steam hole is formed in the wall of the separating chamber at one side of the demister, a discharging hole is formed in the bottom of the separating chamber; a heat exchanger is arranged in the heating chamber, the heating chamber is provided with a heating steam inlet and a condensate outlet, and a feeding hole is formed in one side of the bottom of the heating chamber. The climbing film type evaporator disclosed by the invention is simple in structure and convenient to operate, has a very large heat transfer surface and good heat transfer effect, and is high in heat utilization rate; meanwhile, the retention time of a feed liquid in the heating chamber is short, and the climbing film type evaporator is beneficial to the heat-sensitive feed liquid.
Description
Technical field
The present invention relates to vaporizer technology field, be specially a kind of film-rising evaporator.
Background technology
The method of conventional evaporation heating, is heated to boiling situation by the solution containing fixedness solute, partial solvent is vaporized and is removed, thus improve the device of solute concentration in solvent, be called evaporimeter in the industrial production.Evaporimeter is the workpiece of concentrator, and it comprises heating clamber, separation chamber's two parts.The effect of heating clamber is that steam heats the feed liquid be concentrated by heat exchanger, makes wherein moisture vaporization.The steam generated in feed liquid is called indirect steam.The effect of separation chamber is gone out at the fluid separation applications of entrained with in indirect steam.The type of evaporimeter is a lot, according to the mobility status of solution in evaporimeter, can be divided into circular form and non-circulation type two class.
The feature of non-circulation type evaporimeter be feed liquid in device through once heating, vaporizing and separation process, meet the requirements of the degree of depth when leaving, feed liquid does not circulate, and in device, the time of staying is short, and this is favourable to the evaporation of thermal sensitivity feed liquid.The mode of heating of existing evaporimeter inside is generally Electric heating, and electrical heating wastes energy.
Summary of the invention
The object of this invention is to provide the film-rising evaporator that a kind of structure is simple, heat utilization efficiency is high, heat-transfer effect is good.
The present invention is achieved through the following technical solutions:
A kind of film-rising evaporator, comprise heating clamber and separation chamber, described heating clamber is connected by upper circular tube with separation chamber, be provided with demister in described separation chamber, the separation locular wall of described demister side is provided with indirect steam mouth, is provided with discharging opening bottom described separation chamber; Be provided with heat exchanger in described heating clamber, described heating clamber is provided with heating steam import and condensation-water drain, and bottom described heating clamber, side is provided with charging aperture.
Further, described heating steam import is located on condensation-water drain.
Further, described heating steam import and condensation-water drain are arranged on heating clamber both sides.
The invention has the beneficial effects as follows: film-rising evaporator structure of the present invention is simple, easy to operate, specifically very large heat-transfer area, and heat-transfer effect is good, and heat utilization efficiency is high, time of stopping in heating clamber of feed liquid is short simultaneously, favourable to thermal sensitivity feed liquid.
Accompanying drawing explanation.
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
Fig. 1 is the structural representation of a kind of film-rising evaporator of the present invention.
Wherein: 1; Heating clamber, 2, separation chamber, 3, upper circular tube, 4, demister, 5, indirect steam mouth, 6, discharging opening, 7, heat exchanger, 8, heating steam import, 9, condensation-water drain, 10, charging aperture.
Detailed description of the invention
A kind of film-rising evaporator as shown in Figure 1, comprise heating clamber 1 and separation chamber 2, heating clamber is connected by upper circular tube 3 with 1 separation chamber 2, is provided with demister 4 in separation chamber 2, separation chamber 2 wall of demister 4 side is provided with indirect steam mouth 5, is provided with discharging opening 6 bottom separation chamber 2; Heat exchanger 7 is provided with in heating clamber 1, heating clamber 1 is provided with heating steam import 8 and condensation-water drain 9, bottom heating clamber 1, side is provided with charging aperture 10, and heating steam import 8 is located on condensation-water drain 9, and heating steam import 8 and condensation-water drain 9 are arranged on heating clamber 1 both sides.
During operation, omnidistance formation three, upper, middle and lower zones of different in heating clamber 1.In bottom, because of liquid layer hydrostatic pressure, do not seethe with excitement, only play heat effect; At middle part, temperature rises very fast and comes to life, but heat transfer is also not bery fast; On top, vapour volume increases rapidly, and liquid is smeared into film at tube wall and upwards flowed by tube core formation high speed rising steam flow, causes good heat transfer condition, evaporation is accelerated.Through pipe top, liquid-vapor mixture enters separation chamber 2 vapor-liquid separation, and the discharging opening 6 that feed liquid Neng Guo separation chamber is 2 goes out.
Claims (3)
1. a film-rising evaporator, comprise heating clamber and separation chamber, it is characterized in that: described heating clamber is connected by upper circular tube with separation chamber, in described separation chamber, demister is installed, the separation locular wall of described demister side is provided with indirect steam mouth, is provided with discharging opening bottom described separation chamber; Be provided with heat exchanger in described heating clamber, described heating clamber is provided with heating steam import and condensation-water drain, and bottom described heating clamber, side is provided with charging aperture.
