The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
Fig. 2 shows the structural representation of the gelatin fourdrinier wire dryer heating system of the utility model embodiment, as shown in the figure, this gelatin fourdrinier wire dryer heating system comprises: fourdrinier wire guipure driving wheel 19 that be arranged in parallel and fourdrinier wire guipure driven pulley 1, fourdrinier wire guipure driving wheel 19 and fourdrinier wire guipure driven pulley 1 are connected by fourdrinier wire guipure 2, fourdrinier wire guipure 2 outer cover between fourdrinier wire guipure driving wheel 19 and the fourdrinier wire guipure driven pulley 1 are provided with fourdrinier wire casing 3, fourdrinier wire casing 3 inside are provided with some grades of air-heating units, in the present embodiment, gelatin fourdrinier wire dryer heating system is set to 8 grades of heating systems, wherein first order heating-up temperature requires low, do not need Steam Heating, so described some grades of air-heating units comprise seven grades, seven grades of air-heating units are arranged alternately both sides at fourdrinier wire guipure 2 along the length direction of fourdrinier wire guipure 2, every grade of air heater unit comprises an air heater, the both sides of fourdrinier wire guipure 2 also have been arranged alternately seven fourdrinier wire casing air registers, each fourdrinier wire casing air register and each air heater are oppositely arranged, and seven steam-water separators are connected in series and all are arranged on the bottom of fourdrinier wire casing 3.From fourdrinier wire guipure driving wheel 19 1 ends to fourdrinier wire guipure driven pulley 1 one ends, heating unit is respectively seven grades of the first order to the, air heater should be seven grades of the first order to the mutually, steam-water separator between the air heater then is six grades of the first order to the, first order air heater 6 is provided with condensation-water drain 5a, condensation-water drain 5a place also is provided with 20, the seven grades of air heaters 18 of condensation-water drain visor and is provided with the heating steam air inlet.Fourdrinier wire casing 3 near fourdrinier wire guipure driven pulley 1 one ends is provided with air inlet, and the fourdrinier wire casing 3 of close fourdrinier wire guipure driving wheel 19 1 ends is provided with exhaust outlet.
Acting as of steam-water separator makes condensed water separate with indirect steam, and the higher steam condensate (SC) of relative pressure can carry out double evaporation-cooling in the process that pressure reduces, form new condensed water and indirect steam.Because the density of indirect steam is positioned at the top of steam-water separator less than the density of condensed water, condensed water is positioned at the bottom of steam-water separator, and steam is separated with water.Acting as of air heater utilizes the heat that contains in the steam by air heater air to be heated.
The principle of utilizing the gelatin fourdrinier wire dryer heating system of present embodiment to carry out the gelatin oven dry is: the air that upper level comes, and through the air heater heating, the temperature of air is raise, reduce the relative humidity of air.Air after heating passes glue-line glue is carried out drying, and this moment, the relative humidity of air raise, and entered the heating of next stage air heater, and the next stage glue-line is dried.The process of carrying out the gelatin oven dry is: high temperature, high steam (steam pressure 〉=0.6MPa) heat the hot-air (55 ℃) that the 6th grade of gelatin drying chamber comes by the 7th grade of air heater 18, make air themperature rise to 60 ℃, remove to dry the 8th grade of gelatin in the gelatin drying chamber; (pressure 〉=0.6MPa) enters the 6th grade of steam-water separator 26 (pressure 〉=0.5MPa) through the expansion valve that dams to the condensed water of the 7th grade of air heater 18, part water carries out double evaporation-cooling and becomes indirect steam, enter the hot-air (50 ℃) that the 6th grade of air heater 15 heating level V gelatin drying chambers come, make air themperature rise to 55 ℃, remove to dry the 7th grade of gelatin in the gelatin drying chamber; By that analogy, last condensed water becomes water at atmospheric pressure and discharges system through condensation-water drain 5a, and the condensate temperature of Pai Chuing reaches the purpose of saving steam less than 100 ℃ with this at last.The fourdrinier wire casing air register that is arranged on every grade of relative side of air heater is used for making air to flow successively in different gelatin drying chambers, is convenient to heat and guarantee the temperature of air in every grade of gelatin drying chamber.
As can be seen from the above embodiments, the utility model embodiment has changed traditional fourdrinier wire air heat mode, has utilized the heat enthalpy value of steam to greatest extent, has reduced the consumption of steam; Stepped steam heated mode, the temperature difference is less, and condensate liquid is less, and the liquid film layer that steam and air heat-transfer surface place form is thinner, coefficient of heat transfer height, heat transfer rate is fast, and heat loss is little; This system architecture is simple, is convenient to carry out automation control.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and replacement, these improvement and replacement also should be considered as protection domain of the present utility model.
