Vacuum system in a kind of glycerin monostearate production process
Technical field
The utility model relates to a kind of production equipment of glycerin monostearate, the vacuum system particularly in a kind of glycerin monostearate production process.
Background technology
Molecular clock glycerin monostearate (hereinafter referred to as monoglyceride), is divided into synthesis in process of production, is separated, is atomized shaping three steps.Its monoesters and two or three esters, in distillation link, need be separated by thick monoglyceride, after the distillation equipment that configuration is applicable to, and demand fulfillment two process conditions: the thermal source meeting need of production that temperature control system provides accurately; Meet the stable condition of high vacuum degree produced.The system vacuumized adopted before domestic is generally the little combination that water-ring vacuum pump and rotary-vane vaccum pump add diffusion-ejector pump, and this mode exists following problem: the first, and equipment failure rate is high, and service life is short.Rotary-vane vaccum pump has the situation backspin sector-meeting of gas shock directly to clash into the cavity of vavuum pump in running, in the service life of a monoglyceride production system rotary-vane vaccum pump maximum 1 year.Need the situation by constantly observing lubricating oil in second rotary-vane vaccum pump normal course of operation, to change the pump oil of state deteriorating at any time, operating cost is high.3rd, rotary-vane vaccum pump uses pumping fluid lubricate and fill up the gap of blade and pump chamber, the gas that pump oil is released with system directly contacts, after use couple of days, the micro-tapping that vacuum pump exhaust port is discharged is large, can cough after suction, after eye contact Exhaust Gas, meeting tear stream is more than.
The existence of the problems referred to above directly causes vacuum system unstable, and distil process Parameters variation is large, directly affects the quality of finished product and causes energy consumption too high.
Therefore, be necessary to relate to the vacuum system in a kind of new glycerin monostearate production process, to solve the problems of the technologies described above.
Summary of the invention
The purpose of this utility model is to provide the vacuum system in a kind of glycerin monostearate production process, can realize simple to operate, easy to use, energy-saving consumption-reducing and increasing work efficiency and the effect of quality of finished.
The technical scheme realizing above-mentioned purpose is: the vacuum system in a kind of glycerin monostearate production process, comprise circular response pond, the water-ring vacuum pump be connected with described circular response pond, the multiple Roots vaccum pumps be connected successively with described water-ring vacuum pump, the vacuum distribution be connected with described Roots vaccum pump.
In technique scheme, described Roots vaccum pump comprises the one-level Roots vaccum pump, secondary Roots vaccum pump, three grades of Roots vaccum pumps and the level Four Roots vaccum pump that connect successively.
In technique scheme, described vacuum distribution comprises the first vacuum distribution and the second vacuum distribution, described first vacuum distribution is connected between described three grades of Roots vaccum pumps and level Four Roots vaccum pump, and described second vacuum distribution connects described level Four Roots vaccum pump.
Vacuum system in the utility model glycerin monostearate production process, by the connection of circular response pond and water-ring vacuum pump and multiple Roots vaccum pump, so significantly improve vacuum and stability, all undesirable elements that sliding vane rotary pump produces single vacuum load are stopped, obtain the product of more high-quality, can realize simple to operate, easy to use, energy-saving consumption-reducing and increasing work efficiency and the effect of quality of finished.

Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, those skilled in the art better understand the technical solution of the utility model, below in conjunction with detailed description of the invention also with reference to accompanying drawing, further describe the utility model.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Refer to shown in accompanying drawing 1, show the vacuum system structural representation in the utility model glycerin monostearate production process, vacuum system in the utility model glycerin monostearate production process, comprise circular response pond 1, water-ring vacuum pump 2, multiple Roots vaccum pump 3, vacuum distribution 4.
Have thick ester ester exchange in described circular response pond 1, dehydration etc., be connected with described water-ring vacuum pump 2, described water-ring vacuum pump 2 is connected with multiple Roots vaccum pump 3, and described vacuum distribution 4 is connected with described Roots vaccum pump 3.Wherein, described Roots vaccum pump 3 comprises the one-level Roots vaccum pump 31, secondary Roots vaccum pump 32, three grades of Roots vaccum pumps 33 and the level Four Roots vaccum pump 34 that connect successively.
Described vacuum distribution 4 comprises the first vacuum distribution 41 and the second vacuum distribution 42, described first vacuum distribution 41 is connected between described three grades of Roots vaccum pumps 33 and level Four Roots vaccum pump 34, and described second vacuum distribution 42 connects described level Four Roots vaccum pump 34.Described first vacuum distribution 41 is connected with described one-level Roots vaccum pump 31 and level Four Roots vaccum pump 34 simultaneously, and described second vacuum distribution 42 is connected with described secondary Roots vaccum pump 32 and three grades of Roots vaccum pumps 33 simultaneously.
Vacuum system in the utility model glycerin monostearate production process, by the connection of circular response pond 1 and water-ring vacuum pump 2 and multiple Roots vaccum pump 3, so significantly improve vacuum and stability, all undesirable elements that sliding vane rotary pump produces single vacuum load are stopped, obtain the product of more high-quality, can realize simple to operate, easy to use, energy-saving consumption-reducing and increasing work efficiency and the effect of quality of finished.
Should be understood that, above-mentioned detailed description of the invention of the present utility model only for exemplary illustration or explain principle of the present invention, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, the utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
