Background technology
Pectin is extensively present in fruits and vegetables, can be used as thickening material, jelling agent, emulsifying agent is widely used in food and field of medicaments, is a kind of important pharmaceutical excipient.At present the production method of pectin be that apple residue is broken that pre-treatment, hydrolysis extraction, filtration, filtrate are concentrated, precipitating, washing, dry, make pectin finished product.Wherein, at precipitating and washing step, all needing a large amount of ethanol is spirituous solution, and a large amount of alcohol raffinates that produce after ethanol is used must reclaim, and can recycle on the one hand, to reduce costs, can reduce environmental pollution on the other hand.Therefore, in pectin production, how to accomplish less energy-consumption, recovered alcohol cheaply, just become the major issue that pectin production enterprise must solve.
Utility model content
The purpose of this utility model is to provide the alcohol recovery device in the pectin production that a kind of energy consumption is low, simple to operate, flow process is short.
In order to realize above object, the utility model adopts following technical scheme: the alcohol recovery device in a kind of pectin production, comprise alcohol raffinate storage tank, after alcohol raffinate storage tank, be provided with fresh feed pump, described fresh feed pump by pipeline successively with hot water preheater, fume preheater, rectifying tower string is established, after described rectifying tower, be provided with vacuum tank, vacuum tank is connected with a vacuum pump, described vacuum pump is communicated with described rectifying tower by secondary steam transport pipe, on described vacuum tank, be also provided with raffinate high-temperature water output channel, described raffinate high-temperature water output channel is communicated with described hot water preheater, described rectifying tower tower top is provided with high temperature alcohol volatilization gas and distillates pipeline, described high temperature alcohol volatilization gas distillates pipeline and is communicated with described fume preheater, described fume preheater by pipeline successively with softening water preheater, the first condenser, the second condenser serial connection, on described the second condenser, be provided with the first phlegma output tube and the second phlegma output tube, described the first phlegma output tube is connected with finished product condenser, described the second phlegma output tube is connected with described rectifying tower.
Further, described finished product condenser is connected with alcohol finished product storage tank.
The working process of the alcohol recovery device in the pectin production that the utility model provides is: the alcohol raffinate in alcohol raffinate storage tank (wherein ethanol content approximately 60%) is delivered to hot water preheater by fresh feed pump, it is heating medium that hot water preheater utilizes vacuum tank raffinate high-temperature water output channel raffinate high-temperature water out, alcohol raffinate is carried out to preheating, then alcohol raffinate enters fume preheater and carries out preheating for the second time, the heating medium of fume preheater is that rectifying tower is risen the high temperature alcohol volatilization gas that heat wine essence volatilization gas distillates, alcohol raffinate after the preheating for the second time of fume preheater enters rectifying tower and carries out rectifying separation, from rectifier bottoms high temperature distillation residual liquid out, first enter vacuum tank, under vacuum action, form double evaporation-cooling, in order to reclaim the volatilization steam in distillation residual liquid, the secondary steam reclaiming is brought in rectifying tower through vacuum pump, realized the efficient recovery recycling to heat energy in distillation residual liquid, saved energy consumption, vacuum tank reclaims the raffinate high-temperature water obtaining after secondary steam and enters hot water preheater, the high temperature alcohol volatilization gas distillating from rectifying tower tower top enters again softening water preheater heat exchange cooling after fume preheater heat exchange cooling, enter again the first condenser, the second condenser condenses is processed, the cooling medium of the first condenser and the second condenser is recirculated cooling water, after the second condenser condenses, high temperature alcohol volatilization gas has finally become alcohol liquid, the alcohol liquid part obtaining enters rectifying tower through the second phlegma output tube, be used for controlling rectifying tower tower top temperature, and then control distillates the concentration of the high temperature alcohol volatilization gas of rectifying tower, a part enters finished product condenser through the first phlegma output tube, the heat-eliminating medium of finished product condenser is tap water, in finished product condenser after further cooling, alcohol liquid is down to normal temperature, as alcohol finished product, sending into alcohol finished product storage tank stores.
Alcohol recovery device in the pectin production that the utility model provides, adopt vacuum tank to carry out secondary steam recovery, volatilization steam the distillation residual liquid that recovery is discharged from rectifier bottoms, effectively reduce the steam consumption of whole alcohol recovery device, the distillation residual liquid temperature of generally discharging from rectifier bottoms is more than 100 ℃, with amount of heat, if directly drain, can cause energy wastage, alcohol recovery device in the pectin production that the utility model provides is provided with vacuum tank and vacuum pump, the high temperature distillation residual liquid that makes to flow out from the rectifier bottoms vacuum tank of first flowing through, under vacuum action, form double evaporation-cooling, the secondary steam producing is brought in rectifying tower by vacuum pump again, efficient recovery the heat energy in distillation residual liquid.Fume preheater and softening water preheater are provided in the alcohol recovery device in the pectin production providing at the utility model, can significantly reduce energy consumption, alleviate the cooling system load of whole alcohol recovery device.If employing traditional technology, alcohol raffinate will just can enter into rectifying tower after being preheating to 70 ℃, preheating method adopts vapor heat exchanger to complete conventionally, need to consume a large amount of steam, secondly, the hot water that production plant is required, conventionally also adopt steam heating, still need to consume steam, in addition, requirement traditionally, the high-temperature gas distillating from rectifying tower top will adopt the recirculated cooling water of cooling tower to lower the temperature conventionally, water coolant demand is large, alcohol recovery device in the pectin production that the utility model provides adopts the feature that self needs heating and cooling cleverly, by fume preheater, softening water preheater utilizes heat, both reduced the consumption of steam, dwindled again the load of condenser system.
Alcohol recovery device in the pectin production that the utility model provides heat energy is wherein fully used, and greatly reduces the energy consumption in alcohol recovery, and has advantages of that technical process is short, simple to operate.
