Description
Technical field
The organic solvent that the utility model is mainly used under the negative-pressure operation environment reclaims particularly a kind of pressure conversion hysteria organic solvent energy-saving recovery device that comprises pressure conversion device, condensation retracting device.
Background technology
In the fine chemistry industry industry, organic solvent is normally used for the refining purification of chemical products, organic solvent directly is discharged in the air in subsequently vacuum drying and suction filtration operation, has caused serious environmental to pollute and the wasting of resources, has also increased potential safety hazard simultaneously.
Recovery of Organic Solvent and utilization under the positive pressure operation environment the chemical process abroad just begins one's study from the nineties in last century, as Arnaud Baudot, Miche`le Marin takes the method for pervaporation and rapid condensation for the solution of ethyl acetate in the spices, reclaim ethyl acetate, the rate of recovery can reach 83%.The domestic part scholar Recovery of Organic Solvent that also begins one's study utilizes mixture of ice and water to come condensation to reclaim organic solvent under the positive pressure environment as Wu Yongqing.Carry out under negative pressure in a lot of operational sequences of fine chemistry industry industry, as operations such as vacuum drying and vacuum filtrations, but said method can not be applicable to Recovery of Organic Solvent under the condition of negative pressure, to such an extent as to a large amount of organic solvents directly is discharged in the environment.But up to the present, also do not find the pertinent literature that organic solvent reclaims under the subnormal ambient.
Summary of the invention
The purpose of this utility model is to provide the organic solvent that relates in a kind of chemical process under the negative-pressure operation condition to reclaim, and reduces environmental pollution, avoids the wasting of resources, eliminates the potential safety hazard in production place.
The technical solution that realizes the utility model purpose is: a kind of pressure conversion hysteria organic solvent energy-saving recovery device comprises suction filtration device, pressure conversion device, condensation retracting device, tank, organic solvent concentration alarm, the pipeline that is installed in the automatic control system in the condensing unit and plays the connection effect; Filtering the air inlet of device by pipeline and pressure conversion device couples together, the gas outlet of pressure conversion device is connected by the air inlet of pipeline with the condensation retracting device, the gas outlet of condensation retracting device is connected with tank by pipeline, is provided with organic solvent concentration alarm above the plane of tank.
The utility model compared with prior art, its remarkable advantage: the utility model can be applied to relate to Recovery of Organic Solvent under the vacuumizing environment, has very wide range of application; The utility model is in vacuum filtration and vacuum drying operation, by the pressure converting means, organic solvent in the subnormal ambient is collected, changing malleation into is transported in the condensate recovery system, realization is reclaimed the organic solvent under the subnormal ambient, gas with the outlet of condensation retracting device is passed in the tank simultaneously, absorb remaining a small amount of organic solvent, and above the tank plane, increase an organic solvent alarm, in case concentration overshoot scope is just sent alarm signal, be convenient in time adjust the condensation temperature of condenser system, improve the Recovery of Organic Solvent effect.
Description of drawings
Accompanying drawing is the schematic flow sheet that reclaims according to organic solvent under the recovery negative-pressure operation environment that the utility model proposes.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The utility model pressure conversion hysteria organic solvent energy-saving recovery device comprises suction filtration device, pressure conversion device 1, condensation retracting device 2, tank 3, organic solvent concentration alarm 4, the pipeline that is installed in the automatic control system in the condensing unit 2 and plays the connection effect; Filtering the air inlet of device by pipeline and pressure conversion device 1 couples together, the gas outlet of pressure conversion device 1 is connected by the air inlet of pipeline with condensation retracting device 2, the gas outlet of condensation retracting device 2 is connected with tank 3 by pipeline, is provided with organic solvent concentration alarm 4 above the plane of tank 3.Under the effect of pressure conversion device 1, organic gas in the suction filtration device is transported to the air inlet of condensation retracting device 2 by connecting pipe, this device adopts the secondary refrigeration, tail end in the firsts and seconds refrigeration is respectively arranged with leakage fluid dram, the a small amount of uncooled organic gas of discharging from the gas outlet of condensation retracting device 1 is drained in the tank 3 by connecting pipe, above the plane of this device, be provided with organic solvent concentration alarm 4, in case the discharge rate of organic solvent from tank exceeds the concentration range of estimating, just send alarm signal, to adjust the technical parameter of condensing unit 2.
The utility model pressure conversion hysteria organic solvent energy-saving recovery device, described pressure conversion device 1 is a whole closing appliance, be provided with an air inlet and a gas outlet, a check valve is arranged on this air inlet, this pressure conversion device 1 also is provided with the service life of a time regulator register instrument, and this pressure conversion device 1 can be collected the organic solvent of volatilization and be converted to barotropic state under the negative-pressure operation environment.
The utility model pressure conversion hysteria organic solvent energy-saving recovery device, condenser pipe in the described condensation retracting device 2 adopts full copper bend pipe structure, and employing B-grade condensation, tail end in the firsts and seconds refrigeration is respectively arranged with leakage fluid dram, compressor is positioned at the bottom of condensation retracting device 2, and supporting fan is arranged, automatic control system and parameter dial gauge all are positioned at the top of condensation retracting device 2; Described condenser pipe adopts the insulation material parcel, prevents cold draining.
