Description
Technical field
The utility model relates to a kind of solvent recovery unit, relates in particular to a kind of solvent tail gas retracting device.
Background technology
Domestic at present animals and plants, in the leaching process of medicine etc., can use a large amount of organic solvents, organic solvent is volatile, organic solvent is extracting, concentrated, distillation, in dry process, can produce a large amount of solvent gas, simultaneously in order to guarantee activity and the saving heat energy of product, must reduce its heating-up temperature, the vacuum distillation drying technique that adopts more, to reduce solvent, steam de-temperature, steam degassed body adopts water-ring vacuum pump or water-jet pump to take away through condensed containing molten tail gas more, swabbing action due to vavuum pump, and the temperature limiting of cold water, solvent gas in condenser because flow velocity is fast and two greatly also not under total condensation, just by vavuum pump, taken away.Partial solvent flows in circulating water pool with water, not only causes solvent consumption high, increase production cost, and water is seriously polluted, and partial solvent tail gas enters in workshop and surrounding environment, not only has a strong impact on people healthy.Cause environmental pollution, and part organic solvent gas belongs to inflammable and explosive, cause very big hidden danger to production safety and personal injury.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, a kind of solvent tail gas retracting device is provided, solve in current technology, in the leaching process of animals and plants, medicine, produce a large amount of solvent tail gas cannot high-efficient cleaning except reclaiming, pollute environmental protection and increase the problem of production cost.
For solving above technical problem, the technical solution of the utility model is:
A kind of solvent tail gas retracting device, comprise condensing unit, refrigerating plant recycling can and exhaust pump, it is characterized in that, described condensing unit is connected and composed successively by one-level condensing heat-exchanging pipe, B-grade condensation heat exchanger tube and three grades of condensing heat-exchanging pipes from beginning to end, the liquid solvent of three condensing heat-exchanging pipes exports to collect and is connected on recycling can, refrigerating plant is connected on condensing unit as condensing unit provides exchange system low-temperature receiver, and exhaust pump is connected with the gas outlet of three grades of condensing heat-exchanging pipes.Gas has certain flow velocity when by condensing heat-exchanging pipe, an independent condensing heat-exchanging pipe cannot be condensed to liquid by whole gaseous solvents, therefore the mode that adopts multi-stage condensing heat exchanger tube to connect is strengthened the effect of condensation, solvent tail gas is assembled through three condensing heat-exchange pipework condensations successively, B-grade condensation heat exchanger tube by one-level condensing heat-exchanging pipe not the gaseous solvent of total condensation proceed condensation, three grades of condensing heat-exchanging pipes are failed B-grade condensation heat exchanger tube the gaseous solvent of condensation again and are carried out condensation, finally guarantee the solvent without gaseous state, incoagulability toxic emission can not cause environmental pollution to air, also can not affect the health of human body, and reclaiming the liquid solvent obtaining also can reuse, therefore greatly reduce production cost.
Further, described condensing heat-exchanging pipe adopts bushing type, and cooling tube is wrapped on the Zhou Jing of breather line, and the two ends of breather line are provided with the import and export of solvent tail gas, and bottom is provided with liquid solvent outlet.Cooling tube is wrapped on the Zhou Jing of breather line, has strengthened heat exchange area, has effectively improved rate of heat exchange, effectively reduces energy consumption in the situation that guaranteeing condensation effect.
Further, described refrigerating plant adopts water-cooled, and cooling water is injected into the cooling solvent tail gas of cooling tube in condensing heat-exchanging pipe by refrigerating plant.Water-cooled refrigerating device structure is simple, low cost of manufacture, and operating cost is low, safe to use, and the heat exchanger effectiveness of cooling water in condensing heat-exchanging pipe is high.
Compared with prior art, the utility model advantage is:
Solvent tail gas retracting device described in the utility model adopts the mode of multi-stage condensing heat exchanger tube series connection, the solvent tail gas that next stage condensing heat-exchanging pipe was processed upper level condensing heat-exchanging pipe is processed again, effectively strengthened whole condensation effect, to the rate of recovery of solvent, can reach more than 99%, greatly reduce production cost, also protected that environment and people's is healthy simultaneously; And of the present utility model simple in structure, heat exchanger effectiveness is high, when guaranteeing condensation effect, reduced energy consumption, energy-saving and emission-reduction, small investment, operating cost is low, cost performance is high.
