Description
Technical field: the present invention relates to extraction liquefaction equipment, be directly involved in solvent tail gas recover.
Background technology: lixiviation process prepairng vegetable oil is the method for producing oil of a kind of advanced person, it mainly utilizes solvent first to soak pouring oil-containing stock and does, then the first separation removal solvent of the feature utilizing solvent boiling point temperature low, finally obtain grease and the dregs of rice, production process solvent must evaporate into gas, again gas is become liquid through condenser cooling, and condensation finishing operation is tail gas, tail gas is all discharged in air, containing partial solvent gas in tail gas, solvent gas consumption is caused to increase, production cost strengthens, and cause environmental pollution, solvent is the non-renewable resources extract from oil, how to conquer east in July, 1998 according to Hubei science tech publishing house and write " grease is produced and process technology " 238 pages of Chen Wenlin examination & verification.2, waste gas loss, usual medium-sized and small enterprises offgas discharge amount hourly is 10 cubic metres-12 cubic metres, loss solvent 220kg-250kg, larger oily factory loss 330kg-380kg, scientific research expert finds out a lot of method and solves this difficult problem, but tail gas all reclaims and do not realize.
Summary of the invention: solvent tail gas recover of the present invention is just to provide a kind of refrigeration machine, cool room of utilizing and the tail gas containing solvent is all recycled, it can effectively solve solvent gas and be discharged into air, solvent consumption increases, and causes production cost to increase, the problem of environmental pollution.
The object of the present invention is achieved like this: solvent tail gas recover is by refrigeration machine, airbag, cool room, liquid exports, solvent holding tank, solvent pump, solvent storehouse, gas import, gas exports, buffer bin, charging scraper plate, close auger, infuser, baroceptor, pipe, sense contact device, motor-operated control valve forms, solvent tail gas enters in the airbag in cool room by gas import, airbag and offgas outlet are that in external seal, communicating state is connected, airbag in cool room freely can be elevated position and arrange induction of electric shock device near import orientation, sense contact device is connected with the switch of refrigeration machine, liquid outlet on airbag is arranged in the bottom of cool room, liquid outlet connects solvent holding tank, solvent holding tank is arranged on cool room outside, the outlet of solvent holding tank is connected with the import pipe sealing of solvent pump, solvent delivery side of pump and solvent storehouse seal shape and are connected, the gas outlet of airbag is arranged on the side of cool room and exports lower than gas import higher than liquid, gas outlet pipe seals with charging scraper plate and is connected, connected pipe arranges electric control valve, charging scraper plate arranges baroceptor, open to electric control valve during setting value when charging scraper plate internal gas pressure is low, the feedstock direction of charging scraper plate seals with buffer bin and is connected, the discharging direction of charging scraper plate seals with closed auger and is connected, closed auger seals with infuser and is connected.
Such realization as the course of work of the present invention: when tail gas enters in airbag by gas import, airbag motion after airbag enriches, when the airbag near gas import position is raised to certain height, sense contact device transmission of signal on airbag, refrigeration machine is opened, the solvent liquid cooled down enters solvent holding tank, remaining a part of solvent gas enters in charging scraper plate by gas outlet, when air pressure negative pressure state in charging scraper plate, baroceptor on charging scraper plate starts motor-operated control valve, makes the air pressure in charging scraper plate remain nought state.
Solvent tail gas recover of the present invention is that one utilizes refrigeration machine to cool solvent tail gas, and solvent liquid is all reclaimed, and it can solve effectively leaches exhaust emissions to the problem in air, has saved the energy, has decreased cost, improve benefit, protected environment.
Accompanying drawing illustrates: Fig. 1 is structure principle chart of the present invention, and local structural graph when Fig. 2 is work of the present invention stopping, being now described further by reference to the accompanying drawings.
Concrete enforcement: solvent tail gas recover of the present invention is by refrigeration machine 1, airbag 2, cool room 3, solvent holding tank 4, motor-operated control valve 5, solvent pump 6, gas import 7, gas outlet 8, buffer bin 9, baroceptor 10, close auger 11, pipe 12, charging scraper plate 13, infuser 14, sense contact device 15, solvent storehouse 16, liquid outlet 17 composition, solvent tail gas enters in the airbag 2 in cool room 3 by the connection of gas import 7 sealing state, airbag 2 is that flexible folded flexible is arranged, prevent the air when workshop quits work from entering in airbag 2, the material of airbag 2 has sealing and heat conductive, close gas import 7 on airbag 2 freely can be elevated position and arrange induction of electric shock device 15, sense contact device 15 is connected with the switch control rule of refrigeration machine 1, liquid outlet 17 on airbag 2 is in the bottom of cool room 3, liquid outlet 17 connects solvent holding tank 4, solvent holding tank 4 is arranged on the outside of cool room 3, and the outlet of solvent holding tank 4 is connected with the import pipe 12 of solvent pump 6, and the outlet of solvent pump 6 seals shape with solvent storehouse 16 and is connected, the gas outlet 8 of airbag 2 is arranged on the side of cool room 3 and exports 17 lower than gas import 7 higher than liquid, gas outlet 8 seals with charging scraper plate 13 with pipe 12 and is connected, connected pipe 12 arranges electric control valve 5, charging scraper plate 13 is arranged baroceptor 10, open to electric control valve 5 during setting numerical value when the air pressure in charging scraper plate 13 is low, the feedstock direction of charging scraper plate 13 seals with buffer bin 9 and is connected, the discharging direction of charging scraper plate 13 seals with closed auger 11 and is connected, and closed auger 11 seals with infuser 14 and is connected.
The course of work of the present invention is performed such: when production is carried out, tail gas enters in airbag 2 by gas import 7, airbag 2 is owing to being bending fold flexible setting, so enrich erectile condition from becoming without space contraction by tail gas in airbag 2, when airbag 2 reaches certain height, sense contact device 15 on airbag 2 passes on signal that refrigeration machine 1 is worked, make airbag 2 and inner tail gas cooling down, the solvent liquid that cooling produces exports 17 discharges by liquid and reclaims, and remainder gas continues cooling and exports 8 discharge parts by gas.
The course of work of the present invention is also performed such: when Workshop Production is carried out, due to general in negative pressure state in infuser 14, so close auger 13 also in micro-vacuum state, for preventing entering air in buffer bin 9, air after entering enters charging scraper plate 13 again, close auger 11, in infuser 14, when the air pressure in charging scraper plate 13 is low to when setting numerical value, electric control valve 5 opened by baroceptor 10, the air pressure in charging scraper plate 13 is made to remain on without negative pressure state, so both can prevent from entering air in closed auger 11, the air amount in airbag 2 can be made again to keep poised state, position due to gas outlet 8 is arranged on liquid outlet 17, and solvent gas proportion is greater than air specific weight, so air is upper, solvent gas under, the surplus air ratio contained in the tail gas that gas outlet 8 is discharged is many, even if tail gas penetrates in buffer bin like this, solvent gas runs into the low stock of temperature also can become liquid infiltration wherein, partial air is only had to be mixed away by the stock of buffer bin, this avoid leaking of solvent gas.
