The specific embodiment
Below in conjunction with specific embodiment the utility model is specifically described.
Embodiment 1: as shown in Figure 1; Organic exhaust gas condensation liquefaction retracting device; Comprise air inlet heat exchange chamber 1, the heat exchange chamber 2 of giving vent to anger, feed tube 6; Be respectively equipped with fin 7 in air inlet heat exchange chamber 1, the heat exchange chamber 2 of giving vent to anger, feed tube 6 turns back near former road from the low paramount circuitous back that extends upward, and feed tube 6 its each horizontally disposed horizontal pipeline sections pass each fin 7 respectively; Air inlet heat exchange chamber 1 its top is provided with inlet 10, and heat exchange chamber 2 its tops of giving vent to anger are provided with outlet 11; Air inlet heat exchange chamber 1 its bottom communicates with the bottom of the heat exchange chamber 2 of giving vent to anger through the chamber 3 that is tightly connected, and the chamber 3 that is tightly connected is provided with discharge opeing control outlet.Its chamber that is tightly connected is funnel type.Discharge opeing control outlet connects tapping valve 9.The chamber that is tightly connected can be connected as a single entity with gas heat exchange chamber 1, the heat exchange chamber 2 of giving vent to anger, and also can separate independence, is tightly connected with air inlet heat exchange chamber 1, the heat exchange chamber 2 of giving vent to anger then.
Feed tube 6 is a copper pipe, and its two ends are respectively import 4, outlet 5.
Said fin 7 is an aluminium radiator fin, its concave-convex surface.Each fin vertical array.
Said feed tube 6 is a copper pipe.
Said air inlet heat exchange chamber 1, the chamber wall of giving vent to anger between the heat exchange chamber 2 are connected as a single entity.According to design demand, the material of the air inlet heat exchange chamber 1 after being connected as a single entity, the chamber wall between the heat exchange chamber 2 of giving vent to anger also can be processed by the aluminum fin.
Said feed tube 6 in a vertical plane from low paramount circuitous extend upward arrival above the back turn back near former road.
Operation principle:
Pumping into cryogenic liquid from copper pipe import 4, from top to bottom turns back near former road and is flowed out by outlet 5 in the circuitous at first from the bottom to top top position 8 that arrives of cooling fluid.
High temperature organic exhaust gas is got into by the top of air inlet heat exchange chamber 1; Between air inlet heat exchange chamber 1 aluminium radiator fin and copper pipe, from top to bottom pass through; And turn back through the chamber 3 that is tightly connected from below outlet and to get into the heat exchange chamber 2 of giving vent to anger; Gas passes through between heat exchange chamber 2 aluminium radiator fins and the copper pipe from giving vent to anger from the bottom to top, and air after treatment flows out from the heat exchange chamber 2 tops outlet of giving vent to anger.
Air inlet heat exchange chamber, the heat exchange chamber of giving vent to anger, fin, copper pipe have constituted the main body of heat exchange condenser zone.The flow direction of high-temperature gas produces the process of heat exchange and condensation with the cooling fluid that flows from the bottom to top from top to bottom, is accomplished by the heat exchange condenser zone.The temperature that the heat exchange condenser zone is distributed from top to bottom reduces gradually.Heat exchange condenser zone top is near the temperature that gets into air, and the below is near the temperature of cooling liquid inlet.
When organic waste gas by air inlet heat exchange chamber top from top to bottom through and when touching aluminium radiator fin and the copper pipe of low temperature; Air themperature progressively reduces; Be reduced to one regularly in temperature; Airborne organic exhaust gas and moisture receive condensation meeting liquefy or solid-state, and solid matter can be attached on aluminium radiator fin and the copper pipe, and liquid can flow to the chamber 3 that is tightly connected.
Get into the air in the chamber 3 that is tightly connected through air inlet heat exchange chamber below, its temperature is near the temperature of cooling liquid inlet.Receive the cryogenic condensation effect, most of organic gas composition and moisture are separated in the air.
The air of low temperature is turned back from the bottom to top from the chamber 3 that is tightly connected and is got into the heat exchange chamber 2 of giving vent to anger; Because the Temperature Distribution of heat exchange condenser zone raises from the bottom to top gradually; Air can absorb heat when up flow in heat exchange chamber 2 belows of giving vent to anger; When arriving the top outlet, the temperature before outlet air temperature gets near it.
Another key Design is to run through in air inlet heat exchange chamber and the heat-conducting copper pipe of heat exchange chamber of giving vent to anger cooling fluid bottom horizontal flow sheet in opposite directions; Heat to same horizontal bedding transmits and exchanges; Realize the air inlet heat exchange chamber with the heat exchange chamber of giving vent to anger at the gas heat of same horizontal bedding through exchange to keep relative equilibrium, make its temperature near consistent.
Because whole heat exchange condenser zone Temperature Distribution is that upward relative superiority or inferiority is low; So the temperature changing process of portion's flow air and cooling fluid is following within it: air returns high temperature from high temperature to low temperature; Air gets into the final variations in temperature that flows out little; Only lose little heat, the air waste heat can reuse.Cooling fluid then is from low temperature to high temperature, to return low temperature, same cooling fluid flow into and the variations in temperature when flowing out seldom, only lose seldom cold, significantly reduce the liquid circulation needed energy consumption of freezing.Played the effect of energy-conserving and environment-protective.
Can realize that energy-conservation significantly basic reason is: the heat exchange condenser zone forms when cooling fluid up flows and absorbs heat, the two-way heat exchanging process of release heat during toward current downflow.And the hot-air of coming in turns cold; Except having absorbed the cold that cooling fluid itself brings; Most of cold is to draw the cold air of after condensation, turning back away indirectly; And the cold air heating of turning back away after the condensation, its heat is from the hot-air of coming in, to draw indirectly, the heat exchange between the air (or cold exchange) mainly is that convection current heat absorption and exothermic process are realized in opposite directions fast by cooling fluid.
Summarize above-mentionedly, the Temperature Distribution of heat exchange condenser zone in working order the time is " going up low, the lateral balance of relative superiority or inferiority ", and the state of temperature of cooling fluid is " hang down into and hang down ".The air themperature state is " height advances to exceed ".The processing procedure of air is " heat exchange-condensation-heat exchange ".Utilization sufficient heat exchange method for saving energy realizes that air setting separates the purpose of organic solvent and moisture.
When serious frosting appears in copper pipe and aluminium radiator fin; Valve control capable of using lets copper pipe connect high-temp liquid and defrosts; Owing to generally all be lower than-20 ℃ to the organic gas condensation temperature; So being processed that moisture in the gas is most of can be with the form of ice attached on copper pipe and the aluminium radiator fin, the material of condensation liquefaction nearly all is the organic solvent composition.Before the defrosting, clean the organic solvent emission in the chamber 3 that is tightly connected earlier, defrost again afterwards, defrosting after accomplishing is discharged water, mixes to prevent water and organic solvent, and like this, the organic solvent water content that is reclaimed can be very low, and reuse is worth higher.
The uninterrupted if desired organic exhaust gas of handling continuously can adopt two covering device work, wherein interplanting condensation operation, and another set of defrosting, two covering devices switch in turn.
This device can adopt the mode that blows from air inlet to the conveying of organic exhaust gas or the mode of pump drainage from the gas outlet.
This device reclaims the function except possessing organic exhaust gas, also has both the function that air is dehumidified.

Cooling fluid returns approaching-40 ℃ low-temperature space from the high-temperature region of low temperature-40 ℃ arrival near 60 ℃, when the cooling fluid of lower temperature gets into refrigeration system again, significantly reduces the required energy consumption of circularly cooling.
