Description
The utility model is the mixed intensified recuperated gas purifier of a kind of air water, is used for cooling and purifying compressed air and other gas.Formed by gas buffer part, heat exchanging part and separating part.
Fig. 1 is present just at the 10162-00 of extensive use type pipe type cooler, and its structure mainly is made up of cooler casing, cooler core body 4, water pipe 3, surge chamber 2, blowoff valve 1, separation assembly 5.Weak point is: during with this cooler cooled compressed air when compressed air when cooling import a enters surge chamber 2 through cooler core bodys 4, gas velocity reduces suddenly.Cause oil droplet from gas, to separate, be deposited in the surge chamber 2 and place, air-flow dead angle and fin on; Under the high temperature and oxidation of gas, form very thick carbon distribution on place, air-flow dead angle and the fin, catch fire easily and explode; This cooler heat exchange property is poor, and overall heat-transfer coefficient has only 100W/m
2About ℃, particularly use after a period of time,, cause its cooling performance poorer because surface adhesion one deck hinders the oil film that heat transmits.Therefore, cooled gas temperature still reaches 70～80 ℃, and sometimes even up to 100 ℃, the water content of the saturated air that come out this moment from cooler is higher, and this will constantly discharge condensed water and consume a large amount of compressed air; Gas oil-containing, dust quantity through this cooler are big, can not be applicable to the demanding occasion of gaseous mass; Pipe type heat exchange element, water are walked in the pipe, make leave with rage between the outer fin of pipe, and this structure can produce very big noise because of the sympathetic response of fin chatter and shell when air velocity is big.
The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of and can avoid inner producing carbon distribution, heat transfer coefficient height at cooler, cooling back gas temperature is low, the compressed air water content is low, and can reduce gas oil-containing, dust quantity, the mixed intensified recuperated gas purifier of the air water that the gas extraction system noise is low.
The purpose of this utility model can reach by following technical measures:
1. the bottom of cooler is the taper surge chamber, and the circular tapping hole dish in strip slot or hole, garden is arranged out in this surge chamber.The circular distributive pipe of tapping hole is arranged out at its top; When high-temperature gas enter surge chamber and by the tapping hole dish after mixed with water immediately from distributive pipe ejection, because compressed air is unsaturated, so water is easy to the heat absorption evaporation, there is not the temperature of the water of evaporation can raise yet, gas is washed in high-temperature water, temperature descends, oil and water in the compressed air mix, the mixture of this oil, water, saturated moist air can not produce carbon distribution, and gas feed place does not have the dead angle of air-flow, eradicated the temperature conditions that carbon distribution produces, so cooler can not catch fire.
2. the middle part of cooler is a shell-and-tube heat exchanger, and shell side is provided with deflection plate between pipe, to improve water velocity, circular padding such as round steel, iron wire coiling spiral is arranged in the heat exchanger tube that is provided with vertically, can improve air velocity; Compressed Gas passes through in managing, cooling water flows outside pipe, but enhanced heat exchange like this, after saturated moist air enters tubulation with oil, aqueous mixtures, constantly wash away the heat exchange wall, oil film just can not produce, simultaneously owing to good heat conductivity and water vapor condensation heat release and the turbulent effect of humid air than dry air, heat transfer coefficient is increased substantially, and gas temperature reduces significantly.Simultaneously, owing to adopted the tubular heat exchanger element, gas is walked in the pipe, water is walked outside the pipe, and gas is difficult to blow tubulation, and the tapping hole dish of cooling water, cooler bottom, the screen pack on gas-water separation top all produces resistance or hindrance function to air-flow, therefore, has reduced the noise of cooler.
3. the top of cooler is the separation chamber that has water storage room, and resolution element is centrifugal; The top of separation chamber is provided with the grid type demist filter screen that rolls into filter screen, and the bottom water storage of separation chamber also communicates by the surge chamber of pipeline with the cooler bottom, and water recycles.After the air water mixing rose to separator, wherein profit and impurity separated, and gas passes through filter screen again, can obtain clean gas.
Fig. 2 is the structure cutaway view of the mixed intensified exchanging air water purification installation of gas, and the oil water separator on top is first kind of form of the utility model;
Fig. 3 is the structure cutaway view of second kind of form of the utility model oil water separator.
The utility model is described in further detail below in conjunction with accompanying drawing:
