Description of drawings:
Fig. 1 is the structural representation of this programme.
The specific embodiment: this programme is a kind of improvement to the follow-on dry cleaner of patent before me.It is by laundry wheel 1, the air blast 2 that gas circulation is used in the machine, the cooler 3 that condensation is used, the heater 4 of oven dry usefulness, cooling water pipeline 5, distillation case cooler 9, distillation case 12, reclaim the liquid separator 13 of solvent, the reflux line 14 of solvent after condensing, the thermal source 15 of distillation and oven dry usefulness, solvent cell 16, circulating pump 17, solvent refluxing pipe 19, foreign material gatherer 20, the circulating line 24 of thermal source steam, the pipeline 23 of supply solvent in machine, cleaning spent solvent pipeline 25, high-temperature solvent drop-leg road 7, valve 6, batting gatherer 10, air-introduced machine 26, cryogenic gas feedback pipeline 22, the U-shaped that draining is used is bent 21 compositions.The following outlet of distillation case cooler is set up a feedback pipeline 29 and is had valve 30 in improvement; Set up cryogenic gas feedback pipeline 27, feed back gas control valve 28; Thermal source place in distillation oven dry usefulness sets up pressure switch 31.
Clothing rolls in cylinder during work, the clean cycle pump work, from solvent cell 16, extract liquid flux in pipeline is sent into machine, when the liquid flux collection in cylinder is deposited the value of regulation, close the valve 18 of drawing liquid pipeline, this moment, circulating pump made the liquid flux in the machine become recurrent state, clothing mutual agitation and solvent is contacted evenly with the each several part of clothing under the cylinder effect, after cleaning stirring in required time, close circulating pump and open valve 18, make liquid flux be back to solvent cell; Cylinder rotates at a high speed and begins to dry, and to heating in the machine, evaporates solvent residual on clothing simultaneously, and the solvent gas that is evaporated condenses into liquid at the cooler place, flows in the liquid separator along pipeline, and then flows in the solvent cell; In addition, used solvent contains the dirt on a lot of clothings, close the valve 8 on the supply solvent conduit in machine this moment, open the valve 11 on the cleaning agent pipeline, starting circulating pump extracts solvent in the solvent cell out and sends into the distillation case, under at the bottom of the case of distillation case, heat, make liquid flux evaporation become gas and dirt is stayed, vaporized gas is met the condensation knot and is become liquid again in distillation case cooler, flow back to solvent cell through the liquid separator, it is the solvent that cleans most that the solvent that obtains is reclaimed in distillation, in order to using again.Under the effect of air blast, gas is by illustrated arrow direction in the machine, and the gas that enters cooler is the gas through heating, because the condition of work of cooler is bad, reduced the cold and hot temperature difference, so its recovery ability is very low, the weak effect of Hui Shouing at the appointed time.Before me, increased the high-temperature solvent drop-leg road 7 that has air-introduced machine in the scheme, valve-off 8 is opened valve 6, a part of high-temperature solvent gas in the machine is introduced the distillation case, make cooler in the distillation case that when clothing is dried, originally do not participate in solvent recovery work and distillation case cooler and the machine carry out the recovery operation of solvent simultaneously, improved solvent recovery efficient significantly.In this programme, end opening at distillation case cooler has additional a feedback pipeline 29 and has by-pass valve control 30, observing solvent recovering rate when still insufficient, opening this valve makes the cooled solvent gas of part send back to air-introduced machine to distill again, form the partial circulating of a distillation, guarantee to improve the rate of recovery; In addition, thermal source place in the evaporation oven dry sets up pressure switch 31, this pressure switch is made up of two relays that work independently, the operating pressure of the evaporimeter of control distillation and oven dry usefulness, just control its operating temperature, to add the pressure of thermosetting be 0.4MPa for pressure switch control when distillation work began, later stage to distillation work switches to another pressure switch, operating pressure is risen to more than the 0.6MPa, make the temperature that is transmitted in the distillation case on the boiling point of tetrachloro-ethylene, this has just guaranteed the thorough of distillation, the handover operation of two pressure switches had both guaranteed that distillation thoroughly, also consider energy-conservationly, improved result has accomplished the basic full toxic liquid that reclaims and do not discharge in the water source; This scheme has also been set up cryogenic gas feedback pipeline arranged side by side, and high-temperature solvent gas rest parts gas after condensation is reclaimed of air-introduced machine sucking-off is sent in the cylinder through feedback pipeline again, forms a complete inner loop.The drainage position of liquid separator is outwardly open on the type of not transforming, the portion gas outflow, polluted environment, operating personnel are had greatly injury, patent increase cryogenic gas feedback pipeline and water drainage U-shape are curved before me, avoided the pernicious gas outflow, this programme has been set up a cryogenic gas feedback pipeline arranged side by side again, the first termination moisture trap of this pipeline, and end can connect any position of fuselage in addition, on this pipeline, have valve 28, as required the throughput of adjustments of gas.In cryogenic gas feedback pipeline the gas introducing machine that temperature is lower, reduce the temperature in the part machine, also improved the operating efficiency of machine intercooler.Original type distills not thoroughly when the cleaning solvent, and effluent is the liquid dirt that contains Zellon.After twice improvement, part is not distilled clean solvent gas and is fed back again and deliver to air-introduced machine and distill once more, and the distillation later stage can also increase pressure and temperature, distill and condense very thorough, the dirt of discharging is stiff mud rather than liquid dirt fully, has thoroughly avoided contaminated water source.This programme improves the operation of model machine in the trial employment period and proves: the dry cleaner after improving once more has work quality height, solvent recovery efficient height, can obtain tangible economic benefit, has improved operating environment, has guaranteed workers'health, is welcomed by users.
