Summary of the invention
The purpose of this utility model provides a kind of waste-heat recovery device being applicable to airflow dryer for weak point existing in above-mentioned prior art just.The utility model can be widely used in the airflow dryer of non-weaving cloth, staple in bulk and looped fabric production line, efficiency is high, cost is low, simple to operate advantage that it has, and automatically can be controlled by production line control system.
The purpose of this utility model realizes by following technique measures:
The waste-heat recovery device being applicable to airflow dryer of the present utility model comprises the airflow dryer that one end is provided with wet stock charging aperture, the other end is provided with dry material discharging opening, the damp and hot Waste gas outlet being positioned at airflow dryer wet stock feed inlet end is connected with the air inlet of heat-pipe heat exchanger by wet-emitting blower, damp and hot waste gas filter and corresponding connecting line, and the air outlet of heat-pipe heat exchanger is connected with the wind-supplying mouth being positioned at airflow dryer dry material discharge port end by dry air air-introduced machine and corresponding connecting line.
Heat-pipe heat exchanger described in the utility model is made up of two subregions be up and down communicated with by heat pipe, upper and lower two subregions respectively have one group of import and outlet, upper subregion is to the fresh air preheating after new wind filter filters, and lower subregion carries out discharging after waste heat secondary utilizes to waste gas.Heat pipe in heat-pipe heat exchanger is made up of shell, working media, and one end of heat pipe is evaporator section, and the other end is condensation segment; Evaporator section absorbs the heat of hot fluid, and heat is passed to working medium (liquid state), becomes steam, under small differential pressure action, flow to condensation segment after working medium heat absorption with evaporation and the form of boiling, condenses into liquid simultaneously and releases the latent heat of vaporization, and pass to cold fluid.Condensate liquid by gravity reflux to evaporator section.While working medium so circulates, heat is transmitted to the other end by one end.Its function is that the damp and hot waste gas of discharging through airflow dryer, wet-emitting blower is entered heat-pipe heat exchanger, and the humid air in waste gas is discharged, and waste heat carries out preheating to fresh air, reduces the energy consumption for heating this partial air.
The connecting pipe of the utility model between described damp and hot Waste gas outlet and the air inlet of heat-pipe heat exchanger is provided with temperature measuring equipment, as required to each position thermometric of pipeline, can monitor.
The fiber that the damp and hot waste gas filter of mistake set in the utility model can effectively be cleared up in airflow dryer enters in heat-pipe heat exchanger by pipeline, prevents from resulting in blockage.Be tightly connected between pipeline and pipeline, prevent from emitting outside damp-heat air.
Operation principle of the present utility model is as follows:
When damp and hot waste gas is drawn by the wet-emitting blower of airflow dryer in airflow dryer, entered into the hot junction of heat-pipe heat exchanger by damp and hot waste gas filter, after heat exchange also cooling, be discharged into air; Fresh air is under the effect of dry air air-introduced machine, by the cold junction of new wind filter, heat exchange of heat pipe, dry air pipeline will be delivered to the wind-supplying mouth of airflow dryer after heating, enter in airflow dryer, reduce the heat required for heating fresh air in airflow dryer, reduce costs of production and operation, realize energy-saving and emission-reduction.
The beneficial effects of the utility model are as follows:
1, highly versatile, this device can be widely used in the airflow dryer of non-weaving cloth, staple in bulk and looped fabric production line;
2, efficiency is high, adopts the heat in efficient hot swapping recovery waste gas;
