Description of drawings
Fig. 1 is a workflow synoptic diagram of the present invention.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.Among the figure, housing, precool heat exchanger device 2, chilled water cooler 3, brine cooler 4, re-heat well heater 5, circulation tube 6, self-circulating pump 7, brine freezing machine 8, lithium bromide refrigerator 9, draining sealed can 10, vapor-water heat exchanger 11, expansion tank 1, expansion tank 2 13, expansion tank 3 14.
Embodiment:
The two system moisture eliminators of a kind of gas, comprise housing and be arranged on shell precool heat exchanger device 2 intravital and that connect successively, chilled water cooler 3, brine cooler 4 and re-heat well heater 5, it is characterized in that, described precool heat exchanger device 2 is connected by circulation tube 6 with re-heat well heater 5 interior medias, also be provided with self-circulating pump 7 on the circulation tube 6, also be connected with brine freezing machine 8 on the chilled water cooler 3, also be connected with lithium bromide refrigerator 9 on the brine cooler 4, chilled water cooler 3 also is connected with draining sealed can 10, also be provided with vapor-water heat exchanger 11 on the circulation tube 6, also be provided with expansion tank 1 between brine cooler 4 and the lithium bromide refrigerator 9, also be provided with expansion tank 2 13 between chilled water cooler 3 and the brine freezing machine 8, also be provided with expansion tank 3 14 between precool heat exchanger device 2 and the re-heat well heater 5, also be provided with wire mesh demister 15 between brine cooler 4 and the re-heat well heater 5.
The two system moisture eliminators of this gas are according to 40 ℃ of designs of inlet air temperature in summer, satisfy maximum duty, at this moment do not need the external heat source can be outlet coal gas re-heat to 25 ℃, gas temperature needs part to replenish external heat source between 30～35 ℃, when gas temperature is lower than 30 ℃, because of at this moment the coal gas import and export temperature difference is less, the heat interchanging area demand is very big, thereby all adopts the heating of external steam thermal source.Steam consumption is according to 5 ℃ of designs of gas temperature.
As requested, coal gas at first passes through the precooling of precool heat exchanger device, and gas temperature descends, and has the partial condensation elutriation to go out simultaneously, and the coal gas liberated heat satisfies the caloric requirement that re-heat section coal gas heats up here.After pre-colod-application circulating water temperature rose, the process self-circulating pump was got back to the coal gas behind the re-heat section interchanger heating dehumidification, utilizes the internal system waste heat to greatest extent, with save energy.
Temperature is reduced to 33 ℃ after the coal gas precooling, enters chilled water cooler, and most of water is separated out in this condensation, and temperature is reduced to 8 ℃, enters brine cooler then, and the less water condensation is separated out, and is cooled to 5.3 ℃ simultaneously.In order to remove the water droplet of carrying secretly in the coal gas, wire mesh demister is set, further remove moisture.Enter the re-heat well heater at last, the recirculated water heat temperature raising to 25 that comes with the precool heat exchanger device ℃, relative humidity is less than 50%.The chilled water cooler low-temperature receiver is provided by the lithium bromide refrigerating unit; The brine cooler low-temperature receiver is provided by screw salt solution unit, and water of condensation enters in the phenol puddle that the dehumidification zone has been provided with by automatic draining sealed can, focuses on.Because coal gas contains ash content and adds wet goods impurity, stops up heat exchanger channel easily, and the off-line cleaning function is set on chilled water cooler and brine cooler, removes dirt with steam blast.
In this example, wire mesh demister can be from vibrations, can lean on silk screen vibration itself to remove the water droplet that adheres on it, keep its higher ability of dripping of catching, high-efficiency condensation heat exchanger fin surface is printed on channelizing line, the water droplet that condenses in fin can be got rid of high-efficiency condensation interchanger function of on-line cleaning rapidly, keep the fin surface cleaning, improve heat exchange efficiency.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as housing, precool heat exchanger device 2, chilled water cooler 3, brine cooler 4, re-heat well heater 5, circulation tube 6, self-circulating pump 7, brine freezing machine 8, lithium bromide refrigerator 9, draining sealed can 10, vapor-water heat exchanger 11, expansion tank 1, expansion tank 2 13, expansion tank 3 14 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
