Abstract
The utility model discloses an alkane dehydration device which comprises a pipeline filter, a first steam membrane separator, a second steam membrane separator, a third steam membrane separator, a water circulating vacuum pump and a steam separator, wherein one end of the first steam membrane separator is connected with the pipeline filter, and the other end of the first steam membrane separator is connected with the second steam membrane separator end to end; the second steam membrane separator and the third steam membrane separator are connected end to end; the first steam membrane separator, the second steam membrane separator and the third steam membrane separator are connected with one end of the water circulating vacuum pump; and the other end of the water circulating vacuum pump is connected with the steam separator. According to the utility model, the steam membrane separator replaces the traditional molecular sieve dryer, the alkane and water are separated by the steam membrane separator, the water is further removed by the steam separator provided by the utility model, and the product quality is improved; and the alkane dehydration device disclosed by the utility model is in a simple structure, good in dehydration effect and low in operation cost and is suitable for industrial production.
Description
Technical field
The utility model relates to a kind of device that moisture in the organic matter is separated, especially a kind of alkane dewater unit.
Background technology
The moisture of present industrial use molecular sieve separating device absorption gaseous mixture, comprise two or more at least drying/adsorption towers, air cooler, moisture trap, electric heater, drying tower absorption during work, adsorption tower regeneration, after drying tower absorption is saturated, drying tower transfers regeneration immediately to, another adsorption tower then has regeneration to transfer immediately absorption to, itself so that separation process carry out continuously, but such device shortcoming is: described adsorbent needs regeneration, and the regeneration period is long, and operating efficiency is lower; Energy consumption is large, except supplying with essential heat of desorption, also will provide heating adsorption agent and equipment institute calorific requirement; Alkane in the resolution gas is wasted, and utilization rate is not high; Product purity is low, alkane moisture can only be down to 300ppm.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of energy-conserving and environment-protective to be provided, the alkane dewater unit that production efficiency is high and easy to operate.
Technical scheme: in order to realize above purpose, a kind of alkane dewater unit that the utility model provides comprises piping filter, the first steam film separator, the second steam film separator, the 3rd steam film separator, water follows the formula vavuum pump, steam trap, described piping filter, the first steam film separator, the second steam film separator, the 3rd steam film separator, water follows the formula vavuum pump, and steam trap connects successively.
Described piping filter is provided with flowmeter.
Described piping filter is provided with valve.
Described the first steam film separator, the second steam film separator, the 3rd steam film separator follow the formula vavuum pump by gas outlet pipeline and water and are connected.
Beneficial effect: the utility model is by utilizing the steam film separator to replace traditional mole sieve drier, utilize the steam film separator that alkane is separated with water, utilize again steam trap of the present utility model, further remove moisture, improve the quality of products, the utility model is simple in structure, and dehydrating effect is good, operating cost is low, is suitable for industrialization production.
Description of drawings
Fig. 1 is the structural representation of alkane dewater unit;
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of alkane dewater unit comprises piping filter 1, the first steam film separator 2, the second steam film separator 3, the three steam film separators 4, water follows formula vavuum pump 5, steam trap 6, described piping filter 1, the first steam film separator 2, the second steam film separators 3, the 3rd steam film separator 4, water follows formula vavuum pump 5, and steam trap 6 connects successively, and described piping filter 1 is provided with flowmeter 11, described piping filter, 1 is provided with valve 12, described the first steam film separator, 2, the second steam film separator 3, the three steam film separators 4 follow formula vavuum pump 5 by gas outlet pipeline 21 and water and are connected.
To 1.25MPa, 50 ℃ alkane and the mixed vapour of water (1000ppm) are done processed, gaseous mixture enters the first steam film separator 2 by piping filter 1, described piping filter is provided with the flow that flowmeter 11 can be known gaseous mixture in the display pipes, the valve 12 that described piping filter 1 is provided with can be instant the control pipeline in mixed gas flow, guarantee the dewater unit steady operation, when gaseous mixture enters the first steam film separator 2, the second steam film separator 3, during the 3rd steam film separator 4, water vapour is at the first steam film separator 2, the second steam film separator 3, can see through doughnut under the condition that the pressure differential of the 3rd steam film separator 4 both sides exists, condensation becomes water and enters the first steam film separator 2, the second steam film separator 3, in the temporary tank that the 3rd steam film separator 4 inside are respectively equipped with, the first steam film separator 2, the second steam film separator 3, the 3rd steam film separator 4 follows the true air pump 5 of formula by gas outlet pipeline 21 and water and is connected, described water follows the gas that formula vavuum pump 5 inlet tubes can not coagulate and coagulate and proposes, input moisture separator 6 is made further moisture and is separated, with the vacuum keep of system about-90KPa, by after moisture separator 6 dehydration with 1.22-1.24 MPa, the alkane finished product of 50 ℃ the moisture 10ppm of being lower than directly enters in the finished pot.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
