Description

Environmental protection economizes the solvent recovery unit of the energy

[technical field]

The utility model is a solvent recovery unit of economizing the energy about a kind of environmental protection, it is by the design that forms a closed circulation space between printing or painting device and retracting device, order printing or the gas that painting device volatilized can reclaim in this device fully, through heating for three times and the program of three coolings is carried out the liquid gas shift, the environmental benefit of not only having is economized the effect of the energy, the solvent of volatilization is recycled with season, and then reduces the consumption of solvent, reaches best user mode.

[background technology]

General employed traditional printing or painting device (10), as shown in Figure 1, be to start pressure fan (11) earlier before its running, calandria (12) and air exhauster (13), make baking box (14) inner formation one hot air circulate space and keep an operating temperature, make product via rolling body (15) and unreel body (16) and receive and be delivered to block letter (17) under the synchronous turn of putting and enter in the baking box (14), allow product go up behind the ink print in regular turn the hot-air mediate contact of being sent with the entrance hole (142) of air-conductor (141) and utilize leadout hole (143) that hot-air is extracted out again to form one and go into one and do well and reach the purpose of oven dry by block letter (17).

Aforesaid existing structure, it still has following disappearance: You Zhiqi to print employed solvent generally all to belong to the volatility pernicious gas, residual gas will directly be thrown in the air by air exhauster (13) through leadout hole (143) in the printing back, yet, the gas that is discharged does not pass through any processing fully, except that can't effectively reclaiming the solvent, for arround resident and air will cause severe contamination so that the ozone layer that endangers atmosphere increases environmental burden.

Be to be another existing planar gesture schematic diagram as shown in Figure 2, its printing or painting device (10) are to establish one in the discharging termination of air exhauster (13) to be the retracting device (18) of active carbon tank (181), the residual gas in printing back can be reclaimed through the air exhauster (13) of baking box (14) is adsorbed in the active carbon tank (181), again through heat desorption program and cooling to collect solvent and the discharge water part in the active carbon tank (181).

Aforesaid another existing structure, it still has following disappearance: (one) refers to its active carbon tank (181) especially in the desorption of heating, cooling procedure, though solvent partly can be separated with recovery by work in the moisture content, yet, the moisture content of being discharged still can residual part solvent, so that causes water to pollute; (2) because of its activated carbon is to belong to consumptive material, on using, there is certain time limit,, more allows the waste of user's palpus change the burden of consumptive material and the dual cost of processing consumptive material so the palpus periodic replacement not only brings inconvenience.

[utility model content]

The purpose of this utility model is to provide a kind of environmental protection to economize the solvent recovery unit of the energy, can reclaim fully the gas that prints or painting device is discharged, avoid pernicious gas to leak, simultaneously, gaseous solvent after the recovery can be condensed into liquid once more and be recycled fully by solvent through the condensation accumulator tank, and then the consumption of reduction solvent, also can carry out progressive heating three times through evaporimeter, heat exchanger and heater in regular turn and reclaim air, prevent that not only hot gas runs off, also can shorten and add heat aging to reach the effect of saving the energy.

In order to achieve the above object, the utility model provides a kind of environmental protection to economize the solvent recovery unit of the energy, its printing or painting device are the closed circuits that forms a sealing with a retracting device, this retracting device is provided with a heat exchanger, be connected in a side of heat exchanger and the air exhauster of printing or painting device and the pressure fan of tool heater, opposite side connects a radiator and an evaporimeter of establishing a tool cooling tower respectively, and the condenser of establishing a tool condensation accumulator tank forms a pipeline that communicates with radiator, and between evaporimeter and condenser respectively with the capable two-way circulation of a compressor and establish a pipeline that communicates separately gas is heated and liquid gas shift (being condensation), whereby, make the solvent of volatilization in printing or the painting device baking box be collected the consumption that is stored in the interior recycling of condensation accumulator tank and then reduces solvent, gas with the volatilization in season can circulate and anti-leaking in this loop fully, avoiding water to pollute really and the air-polluting situation takes place, and then effectively improve environmental benefit.

Described environmental protection economizes the solvent recovery unit of the energy, it is characterized in that: printing or painting device are to can be the japanning printing or go up ink print.

Environmental protection of the present utility model economizes the solvent recovery unit of the energy, wherein printing or the painting device pressure fan of establishing a tool heater is dried operation for baking box, utilize air exhauster that heat exchanger, radiator and the condenser that the solvent that volatilizees is evacuated to retracting device carried out three coolings again, make the solvent of volatilization carry out liquid gas and separate and be recovered in the condensation accumulator tank, and cold air promptly is sent to the pressure fan of evaporimeter, heat exchanger and tool heater and carries out three times and heat; Whereby, making the solvent of volatilization be able to store collected recycles in the condensation accumulator tank, reduce the consumption of solvent, gas with the volatilization in season can circulate and anti-leaking in this loop fully, really the water of avoiding traditional printing or painting device and being caused pollutes and air pollution, and then effectively improves environmental benefit and save the energy.

In sum, because the utility model has adopted above-mentioned technological means, thereby it has following progressive effect:

1, the utility model environmental protection economizes the solvent recovery unit of the energy, it is by the design that forms a closed circulation space between retracting device and printing or painting device, the gas that order printing or painting device are discharged can be fully carries out the anxiety that liquid gas shift and nothing leak through the program of heating for three times and three times are lowered the temperature in retracting device, avoiding traditional printing or painting device water to pollute really and the air-polluting situation takes place, and then effectively improve environmental benefit.

2, the utility model environmental protection economizes the solvent recovery unit of the energy, the gas that its printing or painting device are discharged forms the effectiveness that three coolings cause liquid gas to separate by heat exchanger, radiator, condenser and the evaporimeter of retracting device, the solvent of order volatilization can be condensed into liquid once more and be recycled fully by solvent through the condensation accumulator tank, and then the consumption of reduction solvent, reach best user mode.

3, the utility model environmental protection economizes the solvent recovery unit of the energy, the solvent that its printing or painting device utilization are volatilized is after the condenser of retracting device carries out the conversion recovery of liquid gas, air then can carry out progressive heating three times through evaporimeter, heat exchanger and heater in regular turn, originally the temperature that has heated in the loop of sealing prevent that not only hot gas runs off, also can shorten and add the effectiveness that heat aging Yi Da economizes the energy.
