The utility model has the advantages of reasonable structure, high efficiency, energy saving, high durability, reliable use, high heat transferring efficiency, fast circulating speed, etc. The utility model is a novel acid bath evaporating device for viscose fiber.
Description
Graphite block cellular type forced circulation acid bath evaporation device described in the utility model is to utilize piece hole graphite as heat carrier, and realizes a kind of novel chemical industry equipment of acid bath evaporation by the mode of forced circulation.
In the prior art of acid bath evaporation, the acid bath evaporation device has single-action lead pipe natural-circulation evaporator and multiple-effect graphite-pipe natural-circulation evaporator at present.It only is 0.5 kilogram every square centimeter that single-action lead pipe evaporimeter uses the vapour gauge pressure, so production capacity is low, service life is short, steam consumption is high; And multiple-effect graphite-pipe evaporimeter heat transfer coefficient is low, and manufacturing expense height, fault are many.Also have another kind of multistage flash evaporation equipment, heat exchanger and flash vessel in addition, and these equipment mostly are the graphite tubulation heat transmission equipment of import, have problems such as long flow path, investment is high, fault is many." piece cellular type graphite heat exchanger " be not owing to have tube sheet, cushion rubber, graphite-pipe etc., so have the characteristics such as reliable, that the life-span is long of using, and can only use as preheater in the past, to use as the heater of evaporimeter, then exist following problem: (1) is because the aperture in piece hole is too little, resistance is very big, and flow velocity is slow therein, efficient is very low in acid bath.(2) because the little flow velocity in hole is slow, then cause acid bath at boiling in ducts, crystallization, long dirt, be easy to a hole plug.At existing problem in the prior art, a kind of novel graphite block cellular type forced circulation acid bath evaporation device of research and design is very necessary with the problem of the acid bath evaporation that solves viscose rayon.
In view of existing problem in the above-mentioned prior art, the purpose of this utility model be development a kind of rational in infrastructure, energy-efficient, durable in use, use the novel graphite piece cellular type forced circulation acid bath evaporation device reliable, that heat transfer efficiency is high, circulation rate is fast.The utility model adopts the heating clamber of graphite block cellular type heat exchanger as the acid bath evaporation device, and is furnished with forced circulation pump, thereby makes graphite block hole heat exchanger, circulating pump and vaporization chamber always dress up an organism, becomes a kind of novel viscose rayon acid bath evaporation equipment.
The utility model provides a kind of graphite block cellular type forced circulation acid bath evaporation device; Its structure is made up of circulating pump, piece hole graphite heater vaporization chamber and connecting line thereof.The aperture, upper end of piece hole graphite heater and the aperture, side end face of vaporization chamber are connected by bend pipe.The aperture, lower end of vaporization chamber and the axial inlet of circulating pump are connected by pipeline.The aperture, lower end of piece hole graphite heater is connected by the radially outlet of pipeline and circulating pump, constitutes totally-enclosed recycle unit body.Graphite in described in the utility model hole graphite heater is nahlock cellular type graphite or square cellular type graphite.
Graphite block cellular type forced circulation acid bath evaporation device described in the utility model owing to adopted forced circulation pump, makes acid bath flow velocity in the hole remain on 1.0-3.0 meter per seconds, thereby has improved the heat transfer coefficient of piece hole heat exchanger, has also prevented the crystallization plugging; The utility model has possessed following advantage like this:
1, the manufactured goods " piece hole heat exchanger " of the utility model employing graphite product factory become easily and simply the making of evaporimeter as the heating clamber of evaporimeter.
2, the utility model can be avoided all drawbacks that evaporimeter is produced with the graphite tubular heat exchanger; Be that tube sheet is unreliable, problems such as cushion rubber agingly comes off, graphite-pipe fracture; And the use of piece cellular type graphite heat exchanger is very reliable, and service life is also long.
3, the new utility model of this practicality can improve the flow velocity of acid bath in the piece hole greatly, has improved blanket heat transfer coefficient.More much smaller for the required heat transfer area of same evaporability than existing natural-circulation evaporator, therefore can reduce equipment manufacturing cost.
4, owing in of the present utility model hole stable higher flow velocity is arranged, thus go for the material evaporation that crystallization is separated out, can plugging.
In sum as can be known, this practical being extensive use of in fields such as chemical industry will produce positive social benefit and remarkable economic efficiency.
Accompanying drawing of the present utility model is the structural representation of graphite block cellular type forced circulation acid bath evaporation device.Among the figure: 1, circulating pump 2, piece hole graphite heater 3, steam inlet
4, charging aperture 5, indirect steam outlet 6, vaporization chamber 7, discharging opening
8, pipeline 9, fixed gas export 10, coagulate water out
11, drain hole 12, pipeline 13, pipeline
Specific embodiment of the utility model as shown in drawings; Its structure is that the radially outlet of being furnished with the circulating pump of motor (1) is connected by the aperture, lower end of pipeline (12) with piece hole graphite heater (2).The aperture, upper end of piece hole graphite heater (2) is connected by the side face of the same vaporization chamber of pipeline (13) (6).The aperture, lower end of vaporization chamber (6) is connected by the axial inlet of the same circulating pump of pipeline (8) (1).The bottom of the bottom water flush end of pipeline (8) has drain hole (11), and the top of vaporization chamber (6) has indirect steam outlet (5), and vaporization chamber (6) is that discharging opening (7) and charging aperture (4) are arranged on the tank body.The upper end of piece hole graphite heater (2) has steam-gas inlet (3), and its underpart has fixed gas outlet (9) and coagulates water out (10); In the inside of piece hole graphite heater (2) nahlock cellular type graphite is housed.This practical operation principle is: acid bath is after the circulating pump pressurization, flow in the piece hole graphite heater (2), flow through vertical hole of graphite block, rise with the flow velocity of per second more than 1.5 meters, because the velocity ratio Natural Circulation exceeds several times, the aperture is littler than general graphite-pipe, so improved the heat transfer coefficient of hole inner fluid.Steam is through graphite block transverse holes ecto-entad, and tortuous from inside to outside mobile, under the steam flow at high speed, condensation film is very thin, has strengthened the steam heat transfer coefficient.Though the equivalent depth of graphite block is than the graphite thickness of pipe, the thermal conductivity factor of graphite block is better than graphite-pipe, can compensate the shortcoming of wall thickness.Therefore evaporimeter of the present utility model has than the much higher heat conductive efficiency of common Natural Circulation graphite-pipe evaporimeter.Fluid keeps higher speed to flow in the graphite block hole will cause the increase of flow resistance, and the drag overall of the circulation pump lift and the circulatory system adapts.In order to guarantee the normal operation of circulating pump, the utility model adopts more slow-revving circulating pump.
