The present invention uses lithium bromide water solution with specific concentration as an absorbing-condensing medium which supplies high-quality working steam for a multistage steam jetting vacuum device. The present invention only needs a small amount of circulating water, and thereby, energy and water resources are largely saved.
Description
Technical field
The present invention relates to a kind of steam jet vacuum equipment, especially a kind of steam jet vacuum equipment.
Background technique
Advantages such as steam jet vacuum equipment is simple in structure with it, and is easy to operate, and maintenance expenses is low, reliable operation and be widely used in each industrial fields such as metallurgy, chemical industry, food, tobacco, pharmacy, electroceramics.
Along with the continuous development of industrial economy, all kinds of resources and energy consumption strengthen day by day, in order to protect and to economize on resources, realize sustainable economic development, and country has higher requirement to the reasonable utilization of resource and energy consumption.Energy consumption and water resource waste are the key issues of its development and application of puzzlement always in existing vacuum technique is used.The mode that obtains vacuum environment at present mainly contains two kinds, and a kind of is to utilize oil-sealed rotary pump to obtain vacuum, and the shortcoming of this mode is that equipment investment is big, and electric energy consumption is big, inefficiency, maintenance expenses height in addition; The 2nd, adopt steam jet vacuum equipment to obtain vacuum, this mode exists steam consumption quantity big when working efficiency has been saved equipment and safeguarded investment having improved, need a large amount of circulating waters, the water resources consumption waste is serious, equipment is to the summer high temperature environment bad adaptability, shortcomings such as capital investment is bigger, these problems that prior art exists have had a strong impact on applying of steam jet vacuum system.
Summary of the invention
It is little to the purpose of this invention is to provide a kind of investment, and energy consumption is little and only need the steam jet vacuum system of small amount of recycled water.
Technological scheme of the present invention is to adopt certain density lithium bromide water solution to provide high-quality working steam and circulating condensing agent as working medium continuously for vacuum system, this device comprises vaporizer, heat exchanger, radiator, steam distributor, two above steam jet ejectors, water pot, more than one condenser, water pump, vaporizer links by pipeline and steam distributor, steam distributor links with steam jet ejector respectively by pipeline, and steam jet ejector links by pipeline and condenser, and the waste pipe of condenser enters in the water pot, liquid in the water pot is extracted in the heat exchanger by water pump, heat exchanger and vaporizer link by pipeline, and vaporizer links by pipeline and heat exchanger, and heat exchanger links by pipeline and radiator, radiator links by pipeline and condenser, and lithium bromide water solution is housed in the vaporizer.
Above-mentioned waste pipe be the U-shaped waste pipe and mutually the series connection back end of going into waste pipe by a U-shaped manifold wherein enter in the water pot.
Above-mentioned lithium bromide water solution concentration is 50-60%.
Technological scheme of the present invention compared with prior art has following advantage:
1, can reduce steam energy consumption and circulating water consumption significantly.Because existing steam jet vacuum system all is to adopt circulating water as cooling medium, vacuum environment is obtained in injection with water vapor, so water consumption and energy consumption are all very big, and the present invention adopts the lithium-bromide solution of specific concentrations to replace the aqueous solution of the prior art as the circulation working medium, closed circulation operation in device, for vacuum system provides high-quality working steam and circulating condensing agent, so can reduce steam energy consumption and water resources consumption significantly.
2, improved the environmental suitability of vacuum system.Because the present invention has taked new working medium, water-saving result is obvious, and in addition, vacuum system adopts the sealing inner loop mode when work, be not subjected to the influence of external environment substantially, has improved the environmental suitability of device.
3, can significantly reduce equipment investment.Because the present invention creatively adopts bibulous lithium bromide water solution more obvious than condensation effect as absorption condensation agent and water, so just can reduce the outlet pressure of steam jet ejector greatly, thereby reduced the resistance of bleeding in the condenser, the allocating power of sparger is reduced greatly, circulating water cooling systems such as cooling tower in the existing vacuum system, pond, pipeline have also been saved simultaneously, compared with prior art structure is simple more compact so this installs, and the investment of whole vacuum system also significantly reduces.
Be that example is done an energy consumption situation contrast with 1000 tons of refinings of present employed annual output magnesium with the steam jet vacuum system below: (working every day 24 hours, annual) by 300 days
1, coal consumption: refining magnesium vacuum system per hour consumes 1.5 tons of steam, and raw coal per ton produces 5 tons of steam coals per ton by 120 yuan of calculating, and then a year coal consumption expense is: 1.5 * 24 * 300 * 120 ÷, 5 ÷ 10000=25.92 (ten thousand yuan).
Vacuum system of the present invention per hour consumes 0.75 ton of steam when keeping identical working environment, then a year coal consumption is: 0.75 * 24 * 300 * 120 ÷, 5 ÷ 10000=12.96 (ten thousand yuan)
Year the expense of economizing on coal: 25.92 ten thousand yuan-12.96 ten thousand yuan=12.96 ten thousand yuan
2, circulating water consumption: refining magnesium vacuum system per hour needs 100 tons of quantity of circulating water, if the volatilization waste water yield is calculated by 10%, water per ton is by 0.3 yuan of calculating, and then a year waste water resource expense is: 100 * 24 * 300 * 0.3 * 10% ÷ 10000=2.16 (ten thousand yuan).
The vacuum system of the present invention water yield of per hour need lowering the temperature is 4 tons, the volatilization waste water yield is calculated by 10%, then a year waste water resource is: 4 * 24 * 300 * 0.3 * 10% ÷ 1000=0.0864 (ten thousand yuan), then year saving water rate: 2.16-0.0864=2.0736 (ten thousand yuan)
3, can reduce 100,000 yuan of equipment investments such as cooling tower, pond, circulating water cooling system.
4, power consumption: refining magnesium vacuum system is power consumption 30KW per hour, and every degree electricity is pressed 0.6 yuan of calculating, then year power consumption expense: 30 * 24 * 300 * 0.6 ÷ 10000=12.96 (ten thousand yuan).
And the power consumption of vacuum system of the present invention is 1/2 of refining magnesium, promptly 6.48 ten thousand yuan.
Generally building a minimum scale of magnesium factory is 5000 tons, needs the same sampling device of 5 covers.
By above as can be seen if in tame magnesium factory refining magnesium vacuum system, adopt technical solution of the present invention can reduce 500,000 yuan of equipment investments, the energy that can save every year and resource expense (12.96+2.0736+6.48) * 5=107.568 (ten thousand yuan).
