Abstract

The utility model discloses a high-efficient energy-saving dryer and purger for the vacuum dipping lacquer and drying of coils of electric appliances, and carries out a solvent condensation operation and a recollection operation. The high-efficient energy-saving dryer and purger is mainly composed of a vacuum dipping lacquer part, a vacuum drying part, a regeneration part for vacuum pump oil containing solvents, a solvent condensation and recollection part, a freezing and cold trap part, an exhaust gas activated carbon adsorption and regeneration part, and a storage part. Compared with the atmospheric drying equipment, the high-efficient energy-saving dryer and purger can save energy by more than 40%, can recollect solvent by more than 95%, and can improve the work efficiency by 100%; the off gas can be consistent with the state standard of the effluent discharge. The high-efficient energy-saving dryer and purger is safe, not easy to occur the burning accident, the exploding accident, the poisoning accident, etc., reasonable in structural design, and capable of bulk productions in industry.

Description

High-efficient energy-saving dryer and purger
The utility model relates to a kind of with electric apparatus coil carry out vacuum paint dipping and dry, carry out equipment---the energy-efficient dry decontamination equipment that solvent condenses, absorption reclaim simultaneously.
What prior art generally adopted is common baking oven equipment.It finishes functions/drying under normal pressure, but its consumed energy is bigger, and inconvenience is reclaimed, so uneconomical.Evaporate in addition among the air, environmental pollution has certain influence.
The purpose of this utility model be to propose a kind of fairly perfect, energy-conservation, efficient, reduce environmental pollution, economic, practical drying equipment---energy-efficient dry decontamination equipment.
Technical solution of the present utility model: its structure as shown in drawings.It mainly by vacuum paint dipping, vacuum drying, the regeneration of solvent-laden pumping fluid, solvent condenses reclaim, freezing and 7 parts such as cold-trap, tail gas charcoal absorption regeneration and basin form.The vacuum paint dipping part: mainly by the process tank of (1) charged hot system, electric apparatus coil carries out the vacuum paint dipping vacuum drying treatment in jar for it.It is between air-heater and pumping fluid regenerating tank; (2) compound storage tank is stored insulated paint it and process tank and is joined; (3) surge tank is stablized vacuum, pumping fluid is scurried into system when preventing maloperation, and it is connected between insulation compound storage tank, solvent tanker, cold-trap and trap, the vavuum pump; (4) vavuum pump, it is connected with trap, cold-trap, surge tank, and it can reduce solvent boiling point and insulated paint, dimethylbenzene are carried in conduct, the power of the pumping fluid that gives up.
The vacuum drying part: mainly by (1) air-heater, it is one of thermal source of this equipment among being positioned at process tank and heat exchanger; (2) process tank of charged hot system also is one of this equipment thermal source; (3) condenser is connected to after the process tank, before cold-trap and the solvent tanker, and is connected with refrigeration system, trap, and it can be collected the condensation in condenser of high concentration solvent waste gas; (4) solvent tanker is stored the solvent that reclaims the back, links to each other with condenser, cold-trap; (5) composition such as surge tank and vavuum pump, solvent-laden pumping fluid regenerating section: it is mainly by (1) air-heater, condenser; (2) refrigerator is this equipment low-temperature receiver.It collects the condensation of solvent waste gas, and form cooling recirculation system (3) pumping fluid regenerating tank with condenser, trap, cold-trap, regeneration contains the pumping fluid of solvent, be connected in after the process tank, link to each other with condenser, trap, activated carbon adsorber; (4) cold-trap, the content of solvent waste gas in the reduction tail gas.Prolong the active carbon regeneration period, be connected in after condenser, the solvent tanker, before refrigerator, trap, the surge tank; (5) surge tank, vavuum pump etc. are formed the solvent condenses recovery section: mainly by (1) condenser, refrigerator, solvent tanker, cold-trap surge tank, vavuum pump; (2) trap captures the vavuum pump mist of oil contain solvent waste gas, is connected in after condenser, refrigerator, the cold-trap composition such as before vavuum pump, the activated carbon adsorber.Freezing and cold-trap part; Mainly formed by condenser, refrigerator, trap and cold-trap.Tail gas charcoal absorption regenerating section: mainly formed by air-heater, condenser, trap, surge tank, vavuum pump and activated carbon adsorber.End concentration solvent in the charcoal absorption tower section tail gas, make tail gas meet discharging standards, it is connected to after the trap, before the buffer, and is connected with air-heater, process tank, condenser, pumping fluid regenerating tank and surge tank.The basin part mainly is made up of compound storage tank and solvent tanker.Also have buffer and heat exchanger.Buffer wherein is to prevent that the steam in the atmosphere from entering activated carbon adsorber, be connected to after the activated carbon adsorber, heat exchanger is the part of pipeline, utilize waste heat, energy savings, be serially connected in the middle of condenser and the process tank, and be connected with air-heater.
Through trial edition equipment than constant pressure and dry device energy conservation more than 40%, constant pressure and dry equipment evaporates into the solvent in the environment, this equipment is recyclable more than 95%, because pumping fluid, active carbon can use after regeneration repeatedly, so can reduce material consumption, the tail gas that this equipment enters in the atmosphere is to meet discharging standards, work efficiency improves 100%, use this device security reliable, the difficult burning, blast, intoxication accident is desirable efficient, energy-conservation, safe and reliable dry decontamination equipment.
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing 1 is air-heater, the 2nd, the process tank of charged hot system, the 3rd, compound storage tank, the 4th, condenser, the 5th, refrigerator, the 6th, trap, the 7th, solvent tanker, the 8th, pumping fluid regenerating tank, the 9th, cold-trap, the 10th, surge tank, the 11st, vavuum pump, 12, the 13rd, activated carbon adsorber, the 14th, buffer, the 15th, heat exchanger.
