Abstract
The utility model discloses an improved evacuating device, which comprises a primary steam-jet pump A, a primary steam-jet pump B, a condensing heat exchanger A, a condensing heat exchanger B and a water-ring vacuum pump, wherein, the primary steam-jet pump A is connected with the condensing heat exchanger A, the primary steam-jet pump B is connected with the condensing heat exchanger B, the condensing heat exchanger A is connected with the primary steam-jet pump B through a pipeline a, and both the condensing heat exchanger A and the condensing heat exchanger B are connected with the water-ring vacuum pump. Due to the adding of one condensing heat exchanger on the basis of the prior art, which leads to separate use of the steam-jet pumps, the power rate of each steam-jet pump is improved, the requirements for the water-ring vacuum pump are lowered, and the service life of the vacuum pump is prolonged.
Description
Technical field
The utility model belongs to the vacuum technique field of bleeding, and especially relates to a kind of improved steam jet vacuum system.
Background technique
Being in the subtractive process of feedstock production biodiesel with acidifying oil, waste oil, need carry out vacuum distillation, require vacuum this-more than the 0.098Mpa.Existing vacuum system generally is made up of second steam jet pump, condensing heat exchanger, Nash hytor, and the efficient of Nash hytor plays a crucial role to the vacuum system final effect, requires very high to vacuum pump.Because the gas that extracts contains a small amount of acidic materials, very easily cause progressively corrosion failure of sky pump pump chamber, distributor, impeller in the comprehensive function of burn into abrasion, cavitation erosion etc., influence the utilization efficiency of Nash hytor, can't satisfy the requirement of rectification under vacuum.Under the condition of high vacuum degree use condition, the less than two months in working life of pump.
Summary of the invention
The purpose of this utility model is exactly the above problem at the vacuum system existence of present use, a kind of improved vacuum pumping device is provided, be to increase a condensing heat exchanger on the basis of existing technology, vapor pump is separately used, thereby improve the power rate that of vapor pump, reduce requirement Nash hytor.
The purpose of this utility model is achieved through the following technical solutions, this improved vacuum pumping device comprises one-level vapor pump A, one-level vapor pump B, condensing heat exchanger A, condensing heat exchanger B, Nash hytor, described one-level vapor pump A and condensing heat exchanger A link, described one-level vapor pump B and condensing heat exchanger B link, described condensing heat exchanger A links by pipeline a and one-level steam jet ejector B, the condensating water outlet tube of described condensing heat exchanger A is set to U type pipe, so that formation fluid-tight, described condensing heat exchanger A and condensing heat exchanger B link with Nash hytor again, described one-level vapor pump A is provided with steam inlet and process gas inlet, and described Nash hytor is provided with gas evacuation port and condensation-water drain.
The beneficial effects of the utility model: this improved vacuum pumping device is owing to increase a condensing heat exchanger on the basis of existing technology, vapor pump is separately used, thereby improve the power rate that of vapor pump, reduce requirement, prolonged the working life of vacuum pump Nash hytor.
