Abstract
The invention discloses a precooling technique and device for recovering turpentine. The technique is implemented by arranging a precooling device between a distilling kettle and a cooler. The precooling device comprises a precooling tank, wherein a plurality of vapor pipes are arranged in the precooling tank; both ends of each vapor pipe are opened at seal layers on both sides of the precooling tank; the wall of the precooling tank is provided with a water inlet and a water outlet; an upper cover and a lower cover of the precooling tank are flexibly connected with the tank body; a mixture of turpentine and vapor distilled out of the distilling kettle enters the precooling tank; and after cooling water is introduced into the precooling tank to perform precooling, the mixture enters the cooler to be further cooled into a liquid. The precooling technique and device disclosed by the invention have strong pertinence; the device has a simple structure; the precooling technique has the advantage of simple steps, and is very easy to operate; the invention has the advantages of high turpentine cooling rate and favorable oil-water separation effect, and can enhance the recovery rate of the turpentine; and the hot water after precooling can be reutilized, thereby saving the energy consumption and water resources, maximally lowering the cost and enhancing the effectiveness.
Description
Technical field
The present invention relates to a kind of rosin processing and reclaim terebinthine technical field, be specifically related to precooling technology and employed device thereof in the turps removal process.
Background technology
Reclaim in the terebinthine process in the rosin process for processing, the turps and the water vapour that distill through still kettle mix, and the entering water cooler cools off and becomes liquid, pass through water-and-oil separator again with turps and water sepn, reclaim turps.In this process, the profit mixed gas temperature of coming out from still kettle is very high, often above 180 ℃; So pyritous gas directly gets into water cooler, and speed of cooling is slow, and the process long period still can not lower temperature; Still kettle need with the supporting use of a plurality of water coolers, take than large space, even so; Cooling performance is also undesirable, still leaves a part of turps in the water and emits thereupon, not only contaminate environment but also cause heat energy and terebinthine loss.
Summary of the invention
Technological problems to be solved by this invention is; Overcome the above defective; A kind of precooling technology and employed device thereof are provided, the gaseous state turps and the water vapour that distill were reduced temperature before getting into water cooler significantly, get into the water cooler cooling afterwards again; Accelerate speed of cooling, improve cooling performance.
The precooling technology that a kind of turps according to the invention reclaims; Said process step is: between still kettle and water cooler, precooling unit is set; The turps that distills through still kettle and the mixed gas of water vapour get into precooling unit, feed water coolant in the precooling unit and carry out getting into after the precooling water cooler again and further cool off and become liquid.
As preferably, the water coolant in the feeding precooling unit according to the invention is a soft water.
Realize the precooling unit of the precooling technology that turps according to the invention reclaims, comprise the precooling jar, be provided with a plurality of vapour pipes in the said precooling jar, the both ends open of said vapour pipe is in the both sides sealing layer place of precooling jar; The tank skin of said precooling jar is provided with water inlet and water outlet, and the loam cake of precooling jar and lower cover and tank body flexibly connect.
The precooling technology that turps according to the invention reclaims; Be in conventional process flow, to increase by one section precooling operation; Promptly between still kettle and turps water cooler, the precooling jar is set, is communicated with through pipeline between the loam cake of still kettle and precooling jar and between the lower cover of precooling jar and the water cooler; Said precooling jar both sides sealing; Be provided with vapour pipe in the precooling jar, the vapour pipe of profit mixed gas in pipeline gets into the precooling jar from still kettle distills feeds water coolant through the water inlet on the tank skin in the precooling jar; With the profit mixed gas cooling liquid in the vapour pipe; Oil-water mixture body after the cooling gets into water cooler through pipeline again and further cools off, and the water temp that is used in the precooling jar after the precooling rises, and flows out through water outlet; This water coolant is soft water preferably, can be used for the usefulness of steam boiler or other workshop sections.Use precooling unit according to the invention and technology; The gaseous state turps and the water vapour that distill are reduced temperature before getting into water cooler significantly, get into the water cooler cooling afterwards again, accelerate speed of cooling; Oil-water separation is good; The turps recovery is improved, utilization, energy efficient and the water resources of the recyclable row again of hot water that temperature raises after the precooling.
Beneficial effect of the present invention: technology according to the invention and employed device are with strong points, and apparatus structure is simple, manufactures easily, and said process step is succinct; Very easily operation is carried out gaseous state turps that distills and water vapour to get into the water cooler cooling again after the precooling, and speed of cooling is fast; Oil-water separation is good, can improve the terebinthine recovery, and the hot water that temperature raises after the precooling is recyclable to be utilized again; Energy efficient and water resources reduce cost to greatest extent, are enterprise's create beneficial result.

Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further explain.
The precooling technology that a kind of turps of the present invention reclaims; Said process step is: between still kettle and water cooler, precooling unit is set; The turps that distills through still kettle and the mixed gas of water vapour get into precooling unit, feed water coolant in the precooling unit and carry out getting into after the precooling water cooler again and further cool off and become liquid.
As preferably, the water coolant in the feeding precooling unit according to the invention is a soft water.
Realize the precooling unit of the precooling technology that turps according to the invention reclaims, said precooling unit comprises precooling jar 1, is provided with a plurality of vapour pipes 2 in the said precooling jar 1, and the both ends open of said vapour pipe 2 is in both sides sealing layer 3 place of precooling jar 1; The tank skin of said precooling jar 1 is provided with water inlet 4 and water outlet 5, and the loam cake 6 of precooling jar 1 flexibly connects with lower cover 7 and tank body.
