Description
Technical field
The present invention relates to a kind of drying oven, particularly a kind of condensation water residual heat one effect flash evaporation natural air dehumidifying preheating and drying baking oven system.
Background technology
The air drying oven is provided with baking oven air inlet, baking oven gas outlet, wet stock import and dry material outlet, in baking oven, generally include many groups coil heat exchanger group in parallel, each coil heat exchanger group is formed in parallel by a plurality of coil heat exchangers, the import of each coil heat exchanger group is connected with main steam pipe by steam stop respectively, the outlet of each coil heat exchanger is respectively equipped with drain valve, and the outlet of each drain valve accesses respectively total condensate pipe.When vapor stream is crossed each coil heat exchanger and air heat-exchange and, after discharging latent heat, be condensed into the high-temperature condensation water under uniform pressure, high-temperature condensation water enters total condensate pipe through each drain valve; Air enters from the baking oven air inlet, the outer surface of each coil heat exchanger of flowing through, through with steam heat-exchanging after, become hot-air, hot-air and moist material carry out the wet exchange of heat, from the baking oven gas outlet, flow out after taking away the moisture of wet stock, realize the oven dry of material.
After high-temperature condensation water enters total condensate pipe, along the continuous pressure drop of journey, part high-temperature condensation water flash-off of steam, doubly, flow velocity increases approximately 10 times in volumetric expansion more than 1600, and causing prevailing in total condensate pipe is not condensed water, but flash-off steam very easily forms vapour locking; After vapour locking, the back pressure of drain valve increases, and drain valve two ends pressure reduction reduces, and the drain valve discharge capacity descends, and causes the condensed water produced in coil heat exchanger not get rid of in time, and heat exchanger efficiency descends, and hot air temperature can not reach technological requirement, produces thereby impact is normal.For guarantee producing, often need to open the stop valve in parallel with drain valve and carry out in linely, result is that steam leakage when discharging condensed water, steam head on condensed water and flow at total condensate pipe, to overcome the vapour locking resistance; Though guaranteed production, steam utilization reduces, and the unit product steam consumption increases.Therefore existing system or can not normally produce, otherwise waste of steam is serious, and the condensed water sensible heat is not fully used.
Natural air is comprised of dry air and steam, namely in natural air, contains moisture, and especially humidity high season, water capacity can reach 20g/Nm
3Above, water ratio under gaseous state expands more than 1600 doubly in liquid lower volume, so the moisture in natural air has occupied certain volume.When the relative humidity of air reached 100%, airborne moisture reached capacity, and no longer had from the ability of moisture absorption material, and air themperature now is called dew-point temperature, and when air themperature dropped to dew-point temperature, airborne water vapour will condense into dew.The relative humidity of air is lower, stronger to the drying capacity of material.Baking oven in the course of the work, by air blast, blown in baking oven, air blast is when sending into dry air, also steam is sent in baking oven, steam not only hinders the moisture absorption of air to material, reduce the moisture pick-up properties of air, self go back after the heat that the absorption coil heat exchanger discharges as toxic emission, wasted a large amount of heat energy; In addition, due to the existence of steam, air blast need to be sent into more air to meet the needs of the wet exchange of heat, has both increased power consumption, has increased again the air exhaust heat loss.
According to the second law of thermodynamics, heat can not spontaneously be transferred to high temp objects from cryogenic object, realize this process, must consume certain merit, just can make the temperature of cryogenic object lower, reaches the purpose of refrigeration.Lithium-bromide absorption-type refrigerating machine is a kind ofly to take thermal source and be the refrigeration machine of power, mainly generator, condenser, evaporimeter, absorber four major parts and the equipment such as heat exchanger and solution pump, consists of.Lithium bromide refrigerator inside is vacuum environment, for example the shell side of evaporimeter maintenance absolute pressure is 6.54mmHg, water is 5 ℃ of boilings, the water as refrigerant spirt is gone will explosive evaporation, for example, when the higher chilled water of temperature (the being 12 ℃) evaporimeter of flowing through tube side, the water as refrigerant sprayed so outside copper pipe will absorb heat and evaporate from copper pipe, and the chilled water temperature in copper pipe has just reduced (12 ℃ → 7 ℃); After the water as refrigerant evaporation, the pressure of evaporimeter will raise, and in order to keep the pressure very low (6.54mmHg) in evaporimeter, absorber absorbs water vapour by the spray bromize lithium concentrated solution, lithium-bromide solution after the absorption water vapour becomes weak solution, and concentration reduces can not absorb steam again; By generator, weak solution is concentrated, it is thermal source that generator adopts steam usually, and weak solution is heated again, and the rear solution of moisture evaporation in weak solution is concentrated, and keeps absorbability; The isolated steam of generator is undertaken indirectly cooling by cooling water in condenser, the water as refrigerant of liquefy enters the evaporimeter spray again, so moves in endless cycles.Therefore the external pipeline of lithium bromide refrigerator has chilled water import, chilled water outlet; Cooling water inlet, coolant outlet; Steam inlet, refrigeration machine condensation-water drain.
Summary of the invention
The object of the invention is to, overcome problems of the prior art, a kind of condensation water residual heat one effect flash evaporation natural air dehumidifying preheating and drying baking oven system is provided, degree of drying and the rate of drying that can guarantee material reach technological requirement, can improve the utilization ratio of steam again, reduce the energy consumption of unit product.
