Non-condensation gas extraction-type vacuum condenser

Technical field

The utility model relates to a kind of condensing plant of steam, especially the vacuum condenser used of sugar industry boiling pan and evaporator.

Background technology

At present, the sugared vacuum condenser that boils of sugar industry boiling pan use mainly contains two kinds: injecting type vacuum condenser and sprinkle formula vacuum condenser.Ejector condenser generally comprises water inlet pipe, hydroecium, nozzle card, nozzle, juice chamber, trunnion and tail pipe, though this kind condenser is simple in structure, and small investment, processing ease; But, to finish when forming vacuum and air pump, injection water is subjected to the interference of steam condensate (SC), and the effect that forms vacuum reduces greatly.Simultaneously, because water is few with the contact-making surface that juice vapour (being steam) mixes, the time of mixing contact is also short, so the vacuum that forms is lower, refrigerating efficiency is low, and water consumption is big, is unfavorable for saving and environmental protection.Sprinkle formula vacuum condenser generally comprises water inlet pipe, vacuum organizator, dividing plate, tail pipe and vavuum pump, mainly to be water form cascade by dividing plate to this kind condenser mixes in condensate with juice vapour and contact, thereby reach the purpose of condensation, because water and juice vapour contact-making surface are very little, so the effect of condensation is bad.Though aspect water saving, have certain effect, because of its must with the supporting use of vavuum pump, so equipment investment is bigger, operation and maintenance cost height have increased the production cost of enterprise.

The purpose of this utility model provides a kind of water-saving and environmental protection and incondensable gas extraction-type vacuum condenser efficiently.

The utility model is by comprising that the vacuum that vacuum cavity and water inlet pipe thereof and steam inlet pipe constitute forms device, is characterized in that also comprising:

Be located in the described vacuum cavity water spray chamber that communicates with water inlet pipe;

The main non-condensation gas draw-out device that constitutes by hydroecium, the cavity of bleeding, nozzle card and trunnion;

Described vacuum cavity and the connecting pipe between the cavity of bleeding.

Described nozzle card is provided with several nozzles, and the injection focus of each nozzle is certain point of described trunnion inboard.

The tank wall of described nozzle box is provided with the nozzle of a plurality of high speeds sprinklings and atomization type.

The non-condensation gas extraction-type vacuum condenser of above structure is taked to form vacuum and is extracted the form that fixed gas separates.Form the vacuum aspect and adopt sprinkling and atomizer technology at a high speed, water consumption is few, makes water and juice vapour contact-making surface big, and water and juice vapour mixed effect are better, it is faster to form vacuum value of velocity, vacuum is higher relatively, that is to say, because of water can mix better with juice vapour, make under the situation of the equal water yield or water temperature, it is shorter to reach the used excessively time of same vacuum, and the vacuum of formation is also higher, and water is few, condensation effect is high.Owing to contain incondensable gas in the juice vapour, extract the fixed gas aspect and then take the mode of separating with the device body that forms vacuum, purpose is to make the water spray of focusing not be subjected to the influence of other carbonated drink, thereby the water consumption is reduced.

Description of drawings

Fig. 1 is that the utility model structure master looks schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is elaborated.

Looked in the schematic diagram as can be known by structure master of the present utility model shown in Figure 1, in the left side of vacuum cavity 5, be provided with water inlet pipe 1, have steam inlet pipe 2, this steam inlet pipe 2 links to each other with the juice steam pipe of boiling pan or evaporator by pipeline, input steam.Be provided with the water spray chamber 4 that communicates with water inlet pipe 1 in the centre of vacuum cavity 5, uniformly on the tank wall of this water spray chamber 4 be provided with a plurality of nozzles 6 that can spray at a high speed with atomization type,, can water be sprayed all even atomizing ground as spiral nozzle on sale on the market.The shape of water tank 4 also can make circlewise, spherical, cylindric and prismatic etc.At the lower port of vacuum cavity 5 drainpipe 3 that has been fixedly connected.Vacuum cavity 5 is communicated with the cavity 12 of bleeding by connecting leg 7 at the top.Bleeding above the cavity 12, be provided with hydroecium 9 and hydroecium water inlet pipe 8 thereof, below hydroecium 9, be provided with water spray card 11.Be laid with a plurality of water spouts 10 on the water spray card 11, the water in the hydroecium 9 can be concentrated to be sprayed onto on the inboard point of the trunnion 13 that is arranged on cavity 12 lower port of drawing water.In Fig. 1, the water spray focus of each nozzle 10 is inboard mid points of trunnion 13.Below trunnion 13, be connected with tail pipe 14, be used for discharging the bleed water and the on-condensible gas of cavity 12.In Fig. 1, it is horn-like that trunnion 13 makes into opening up and down of receipts waist, and its purpose is that the gas in the cavity 12 of bleeding is had compression.

The operation principle of this non-condensation gas extraction-type vacuum condenser is: the water vapour in water and boiling pan or the evaporator enters in the vacuum cavity 5 from vacuum cavity water inlet pipe 1 and steam inlet pipe 2 respectively, and described water vapour also is juice vapour.The water that enters from water inlet pipe 1 enters into the water spray chamber 4 of vacuum cavity 5, is sprayed at a high speed by on water spray chamber 4 tank walls each and atomizer 6 spills and is sprayed onto in the vacuum cavity 5 again.Spray with the water of atomizing and in vacuum cavity 5, fully contact mixing with juice vapour, the rapid condensation liquefy of juice vapour water, the volume that steam is mixed sharply descends and diminishes, thereby formation vacuum, condensed condensed water is discharged through drainpipe 3, owing to be condensate in the vacuum that forms in the vacuum cavity 5, constantly absorbs the juice vapour in boiling pan or the evaporator, eliminate the moisture content of liquid glucose in the sugar bowl, play the effect that concentrates liquid glucose.In the condensation process that vacuum cavity 5 produces, because of containing incondensable gas in the juice vapour, this gas can't be got rid of in vacuum cavity 5.Therefore, the utility model is provided with a cover air extractor, and the cavity 12 of bleeding of this device is communicated with vacuum cavity 5 by connecting leg 7.Incondensable gas rises and enters in the cavity 12 of bleeding by connecting leg 7.Water enters hydroecium 9 from the water inlet pipe 8 of hydroecium 9, on certain point in trunnion 13 inboards of each nozzle 10 vectored injection on the water spray card 11, discharges through tail pipe.Focus at water and in the process of injection incondensable gas to be carried secretly and compress, incondensable gas is entered in the atmosphere by tail pipe 14.Thereby finish the incondensable gas process that extracts.In practical process, the also vacuum available pump replacement of cavity of bleeding.
