Description
Technical field
The present invention relates to a kind of evaporimeter, particularly a kind of band expansion chamber internal circulation evaporator.
Background technology
The energy consumption of evaporimeter is very big, and much can't mostly adopt evaporation and concentration with the wastewater from chemical industry of biochemical process processing at present, reaches zero-emission, eradicates the pollution of waste water.
The big evaporimeter of production capacity has following tangible drawback when using at present:
One, hot short circuit phenomenon appears, when the material that is heated to boiling point is not also overflowed gas fully, when temperature descends, enter heating clamber by circulation pipe once more through forced circulation pump, cause temperature of charge rising in the heating clamber, heat-transfer effect descends because of heating steam and material temperature difference reduce, and evaporation production capacity is descended.
Two,, the flow of forced circulation pump there is requirement, thereby makes the power of motor of pump become one of main part of evaporimeter energy consumption in order to satisfy material flow requirement in the heating clamber.
Three, because the space that traditional evaporimeter does not have the evaporating, concentrating and crystallizing composition granule to grow up, crystallization is circulated in evaporimeter all the time, increased the probability that the heating clamber tubulation is blocked greatly, simultaneously because particle is little, increase subsequent handling and handle the difficulty of crystallization, the generation material density of solid raises. and the forced circulation pump power consumption increases.
In the evaporimeter of extensive use at present, material enters vapor-liquid separation chamber after entering evaporimeter after being heated to boiling point in the tube bank that is pumped to heating clamber, gas is overflowed, after enter pump via circulation pipe again, the heating clamber heat transfer efficiency depends on the flow velocity of liquid in tube bank to a great extent, and the flow velocity big heat transfer efficiency of healing is higher.So go round and begin again, constantly gas being overflowed reaches concentrated purpose.The flow of evaporimeter pump depends on number of tubes in the heating clamber, and evaporimeter production capacity is bigger, number of tubes also the more, pump discharge is also bigger, and the flow of pump is directly proportional with the pump power consumption.In a single day evaporimeter material when concentrated has crystallization to separate out, and all crystals all participates in circulating and the power consumption of pump is directly proportional with material density, and crystal participates in circulation increases material density, increases power consumption again.Another problem that influences production capacity of this evaporimeter is to enter vapor-liquid separation chamber after liquid leaves heating clamber, just after circulation pipe enters pump, enter heating clamber once more no more than the swabbing action because of forced circulation pump of gas being overflowed just and cause hot short circuit phenomenon, evaporator capacity so decline.
Summary of the invention
Technical problem to be solved by this invention provides a kind of band expansion chamber internal circulation evaporator, and it has eradicated hot short circuit phenomenon, and therefore evaporability is improved.
For solveing the technical problem, the invention provides a kind of band expansion chamber internal circulation evaporator, it is characterized in that, it comprises material inlet, vapor-liquid separation chamber, the vapour-liquid uniform device, forced circulation pump, heating clamber outer ring heating tube, heating clamber inner ring heating tube and crystallization expansion chamber, material inlet is between vapour-liquid uniform device and heating clamber outer ring heating tube, heating clamber inner ring heating tube is between the heating tube of heating clamber outer ring, vapor-liquid separation chamber is positioned at the top of vapour-liquid uniform device, forced circulation pump is positioned at the below of heating clamber outer ring heating tube, and the crystallization expansion chamber is fixed on the below of forced circulation pump.
Positive progressive effect of the present invention is: when material leaves heating clamber in the band expansion chamber internal circulation evaporator of the present invention after heating, be sprayed at uniformly through the vapour-liquid uniform device on the surface of vapor-liquid separation chamber's liquid level, the space increases gas suddenly and overflows just quite complete, eradicated hot short circuit phenomenon, therefore evaporability is improved; Can save the energy consumption 50% of electricity.
Description of drawings
Fig. 1 is the structural representation of band expansion chamber internal circulation evaporator of the present invention.
The specific embodiment
Lift a preferred embodiment below, and come the clearer the present invention that intactly illustrates in conjunction with the accompanying drawings.
As shown in Figure 1, band expansion chamber internal circulation evaporator of the present invention comprises material inlet 1, vapor-liquid separation chamber 2, vapour-liquid uniform device 3, forced circulation pump 4, heating clamber outer ring heating tube 5, heating clamber inner ring heating tube 6 and crystallization expansion chamber 7, material inlet 1 is between vapour-liquid uniform device 3 and heating clamber outer ring heating tube 5, heating clamber inner ring heating tube 6 is between heating clamber outer ring heating tube 5, vapor-liquid separation chamber 2 is positioned at the top of vapour-liquid uniform device 3, forced circulation pump 4 is positioned at the below of heating clamber outer ring heating tube 5, and crystallization expansion chamber 7 is fixed on the below of forced circulation pump 4.
Same when keeping in the heating clamber tube bank material flow owing to tube bank is divided into two parts, a part advances into heating clamber outer ring heating tube advancing forced circulation pump, another part enters heating clamber inner ring heating tube after going out forced circulation pump, the flow of forced circulation pump has only 1/2 of existing evaporimeter when same quantity of restraining and flow velocity like this, and the power consumption of forced circulation pump also has only 1/2 of existing evaporimeter.
Band expansion chamber internal circulation evaporator of the present invention is provided with the crystallization expansion chamber, in a single day has the most of crystal of crystallization not participate in circulation when concentrated, and the density of material can not increase because of there being crystal to produce, and the power consumption of forced circulation pump no longer rises because of crystal produces.When material leaves heating clamber in the band expansion chamber internal circulation evaporator of the present invention after heating, be sprayed at uniformly through the vapour-liquid uniform device on the surface of vapor-liquid separation chamber's liquid level, it is just quite complete that the space increases the gas effusion suddenly, eradicated hot short circuit phenomenon, and therefore evaporability is improved.
The operation principle of band expansion chamber internal circulation evaporator of the present invention is as follows: after material enters evaporimeter, because forced circulation pump operation, spent material descends along heating clamber outer ring heating tube and enters the crystallization expansion chamber, follow and the following crystal in the material, bigger because of crystallization expansion chamber space, flow velocity descends and sedimentation.In infall process, constantly grow up material after sedimentation, being pumped to heating clamber inner ring heating tube by forced circulation again heats, after the vapour-liquid uniform device, evenly spread to the liquid level of vapor-liquid separation chamber, the material that need are evaporated, discharge by top, separation chamber, material enters heating clamber outer ring heating tube once more then, and so, going round and beginning again reaches concentrated purpose.Because material turnover forced circulation pump all is the same heating surface (area) (HSs of heating tube, the flow of forced circulation pump has only half of conventional evaporator.Simultaneously because of material heating distance doubles, the density contrast of material turnover heating clamber increases, the forced circulation pump lift is required just to reduce, therefore, band expansion chamber internal circulation evaporator of the present invention half of not enough original evaporimeter on power consumption.
Material enters at material outlet, through the vapour-liquid uniform device, it is indoor to make material be sprinkled upon vapor-liquid separation equably, because gasifying surface is long-pending big, and conventional evaporator can only concentrate on a certain part, therefore band expansion chamber internal circulation evaporator of the present invention can have been avoided the hot short circuit phenomenon of existing evaporimeter effectively, has improved the efficient of evaporimeter.Material has the sedimentation separation process simultaneously in concentration process, even concentrating when containing crystal or solid material, also can avoid solid to participate in circulation effectively, avoid the heating tube fouling, and phenomenon results in blockage.Crystal is again the process of nuclei growth in infall process, and band expansion chamber internal circulation evaporator of the present invention had both reclaimed crystallization heat, made crystal grain greater than conventional evaporator again, is easy to separate.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make numerous variations or modification to these embodiments.Therefore, protection scope of the present invention is limited by appended claims.
