Abstract
The utility model discloses an energy-saving and environment-friendly device used for recovering coating and solvent in dry process sections. The device is internally provided with a shifting mode used for guiding in outdoor temperatures and temperature of a refrigerating unit, an airflow exchanging process before and after recovering, and corresponding pipe valves. The device is characterized by comprising a pipeline used for airflow circulation, an adjusting wind valve used for shifting the indoor air and outdoor air, an outlet (2) used for guiding out a gas containing coating and solvent, a pipeline fan (4) used for leading the gas into a recovering device, a heat-energy recovering and heat-exchanging device (5) used for converting the hot gas or cold gas mutually, and a condensation heat exchanger (6) which is used for reducing the temperature of the gas and condensing and separating out the liquid; and the two heat exchangers in the device are fin-type rectangles. The refrigeration machine is not used in winter, the outdoor cold air is guided in so as to circularly cool down the condensation heat exchanger (6) by the temperature shifting mode; the recovery rate of the solvent is not less than 98%; and the re-utilization of the heat energy after drying can save the energy by more than 55%, and the energy-saving and environment-friendly device can be applied to drying process sections of various coating production lines.
Description
Technical field
The utility model relates to a kind of energy-saving environmental protection device, particularly relates to energy-conserving and environment-protective of a kind of drying process section and paint solvent retracting device.
Background technology
Existing variously can distribute in the air about production line coating process dryer section space of a whole page coating in baking version process gas and heat energy that volatilization produces that is heated, its penetrating odor is the contaminated environment air both, wastes resource again, also is unfavorable for environmental protection.Also do not retrieve at present the article and the patent of relevant this respect technological improvement.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly can reclaim the energy-saving environmental protection device that paint solvent and heat energy utilize again.
For addressing the above problem, the technical solution of the utility model is: the principle for liquid is formed in condensation according to paint solvent gas chance, design is useful on and imports outdoor temperature and refrigeration unit temperature switch mode and reclaim front and back air-flow exchange process and corresponding pipe valve in this retracting device, it is characterized in that: described recovery air-flow exchange process includes heat outlet (2), energy recovery heat exchanger (5), the airflow line that condensing heat exchanger (6) is connected with pipeline fan (4), a pipeline fan (4) that is used for gas suction retracting device, one is converted to hot gas cold air or cold air is converted to the energy recovery heat exchanger (5) of hot gas, one with the gas after energy recovery heat exchanger (5) cooling again condensation separate out the condensing heat exchanger (6) of liquid.Described energy recovery heat exchanger (5) is positioned at the top that paint solvent reclaims condensing heat exchanger (6), pipeline fan (4) is positioned at the left side of energy recovery heat exchanger (5), condensing heat exchanger (6) is connected with thermal energy converter (5), described retracting device includes the temperature switch mode, its removal process is: the gas that produces when with pipeline fan coating production line being dried the spraying aspect is incorporated into energy recovery heat exchanger (5), carry out the heat exchange cooling first time, gas after the cooling imports condensing heat exchanger (6) again, the condensation in condensing heat exchanger (6) of paint solvent gas is become liquid and is separated out, flow in the solvent collection bucket (8), remaining gas returns this heat exchanger again, after the gas that returns heats up in thermal energy heat exchanger (5), again by pipeline air exhauster suction oven dry road.Thereby reaching energy recovery utilizes and paint solvent gas recovery purpose again.The rate of recovery is 〉=98%, and baking back heat energy utilization can make coating stoving process section energy-conservation more than 55%.
In addition, when temperature is low in the winter time, the refrigeration machine of can stopping using refrigeration, utilize the temperature switch mode of retracting device, with manually or automatically opening the temperature switch mode valve that is connected with condensate and heat exchanger (6), outdoor cold air is introduced condensing heat exchanger (6) by the cold wind mouth, the cold air that is introduced into circulates cooling condensation heat exchanger (6), make and contain solvent gas and be condensed into liquid and flow into collecting vessel (8), the residual gas of separating out behind the solution flows into energy recovery heat exchanger (5) by after the heat exchange by pipeline, draw back drying baker by pipeline fan (4) and mend wind, and the cold air of introducing from the cold wind mouth is excluded outdoor behind the cooling condensation heat exchanger.When summer temperature is high, but closing temperature switch mode valve stops hot outdoor air to enter retracting device, starting refrigeration machine refrigeration, thus make the retracting device system works, reach energy-conservation recovery purpose.
In sum, the utility model advantage is: small investment, easy to operate, energy-conserving and environment-protective, can obtain economy and environmental protection double benefit.As adopt this patent retracting device, can reach the energy-conserving and environment-protective purpose fully.
Description of drawings
The utility model is described in more detail below in conjunction with accompanying drawing
Accompanying drawing is section energy-conserving and environment-protective of the utility model drying process and paint solvent retracting device schematic diagram
Section energy-conserving and environment-protective of the utility model drying process and paint solvent retracting device are made up of heat outlet (2), energy recovery heat exchanger (5), condensing heat exchanger (6) pipeline fan (4).
The specific embodiment
Energy-conservation and the paint solvent retracting device structure of the utility model production line oven dry as shown in drawings.Retracting device comprises the temperature switch mode, reclaims front and back air-flow heat exchanging process and corresponding pipe valve.Its removal process is: gas produces drying road (1) heat outlet (2) and enters energy recovery interchanger (5) and carry out heat exchange first time and lower the temperature during drying baker oven dry coating, gas after the cooling heat exchange imports condensing heat exchanger (6) again and carries out condensation, gas is become liquid, the paint solvent of separating out flows into solvent collection bucket (8), after remaining gas is warming up to, use pipeline fan (4) suction oven dry road again in heat recovering heat exchanger.
When outside air temperature is very low in the winter time, the refrigeration machine of can stopping using.The steps include: to open outdoor air intake valve, close the GM Refrigerator Working air door, open valve for air exhaust, close refrigeration machine, open air-introduced machine, cold air is filtered, and outdoor cold wind circulation begins the cooling heat exchanger that circulates, and makes the solvent gas cooling be condensed into liquid, flow into the solvent collection bucket, reach and reclaim the solvent purpose, residual gas enters indoor after heat exchanger heats, to increase indoor circulation.Because the low and inactive refrigeration machine of temperature in winter, thereby saved the electricity consumption power consumption.
