Embodiment Construction

[0013] A new type of vacuum system for pumping water and steam such as figure 1 and figure 2 As shown, it consists of main steam jet vacuum pump 1, lithium bromide absorption system 2, absorber 3, spray piping system 4, exhaust piping system 5, valve 6, condenser 7, primary ejector 8, cooling water inlet 9, condenser 10. Composed of secondary injector 11, cooling water inlet 12, tertiary injector 13, vacuum pump, etc.

[0014] When working, first open the third-stage ejector 13, and then turn on the condenser 10 cooling water after reaching the vacuum degree requirement, then turn on the condenser 7 cooling water, and the second-stage ejector 11; after reaching the vacuum degree requirement, open the first-stage ejector 8, and the vacuum degree When the lithium bromide absorption system 2 absorbs the environmental requirements, the valve 6 is closed, and the pre-vacuum system is closed. At this time, the main steam jet vacuum pump 1 is turned on, and the lithium bromide abso...

Abstract

The novel energy-saving water pumping vapor vacuum system includes vapor jetting pre-vacuum system, lithium bromide absorbing system and main vacuum pump, the air outlet of the main vacuum pump is connected to the absorber in the lithium bromide absorbing system, and the condensator in the vapor jetting pre-vacuum system is connected to the absorber in the lithium bromide absorbing system. The technological scheme of the present invention is that water solution of lithium bromide in certain concentration is made to pass through the lithium bromide absorbing system and low temperature concentrated lithium bromide solution with powerful hydroscopicity is provided for absorbing vapor continuously. The technology of the present invention has the advantages of greatly lowered vapor and cooling water consumption, raised vacuum system stability and novel structure.

Description

technical field [0001] The invention relates to a vacuum system for pumping water and steam, in particular to a novel energy-saving vacuum system for pumping water and steam. Background technique [0002] The steam jet vacuum system is widely used in food, metallurgy, medicine, chemical industry, tobacco and other industries due to its simple structure, convenient operation, low maintenance cost, reliable operation and strong environmental adaptability. [0003] With the continuous development of the industrial economy, the consumption of various resources and energy is increasing day by day. In order to protect and save resources and achieve sustainable economic development, the country puts forward higher requirements for the rational use of resources and energy. In the application of existing vacuum technology, energy consumption and waste of water resources have always been the key problems that plague its development and application. At present, there are two main ways...
