Abstract
The utility model provides a vacuum equipment in production of tetrabromoethane, comprising a Roots vacuum pump, a Roots pump circulating water pump, a water ring vacuum pump and a water ring pump circulating water pump, which is characterized in that: the air inlet of the Roots vacuum pump is communicated with the condenser of the equipment in production of tetrabromoethane; the water outlet of the Roots pump circulating water pump is communicated with the water inlet of the Roots vacuum pump through the pipeline ; the water inlet of the Roots pump circulating water pump is communicated with the water source; the air inlet of the water ring vacuum pump is connected with the air outlet of the Roots vacuum pump; the water outlet of the water ring pump circulating water pump is communicated with the water inlet of the water ring vacuum pump through the pipeline; the water inlet of the water ring pump circulating water pump is communicated with the other water source. The utility model has solved the prior problem of high energy consumption and the formed vacuum instability of the steam jet vacuum pump in the production of tetrabromoethane.
Description
Technical field
The utility model relates to the concentrating under reduced pressure equipment in the tetrabromoethane production is carried out vacuumizing device.
Background technology
In the tetrabromoethane production technique, the tetrabromoethane work in-process must be removed the lower boiling composition through concentrating under reduced pressure, and decolouring becomes finished product.The required vacuum of concentrating under reduced pressure is formed by steam jet vacuum pump.The vacuum instability that steam jet vacuum pump forms, influence concentrates quality, and this pump power consumption is high.A SYPO type steam jet vacuum pump, steam consumption is at least 250kg/h, water coolant 23m
3/ h.From improving the quality of products and energy-conservation angle, must replace with vacuum system efficient, less energy-consumption.
Summary of the invention
The utility model provides the vacuum apparatus in a kind of tetrabromoethane production, and it has solved the vacuum problem of unstable that the steam jet vacuum pump power consumption of existing use in tetrabromoethane is produced is high, form.
This vacuum apparatus comprises Roots vaccum pump, lobe pump water circulating pump, water ring vacuum pump, water-ring pump water circulating pump; The inlet mouth of Roots vaccum pump communicates with condenser in the tetrabromoethane production unit; The water outlet of lobe pump water circulating pump communicates with the water-in of Roots vaccum pump by pipeline, and the water-in of lobe pump water circulating pump communicates with the water source; The inlet mouth of water ring vacuum pump and the air outlet of Roots vaccum pump join; The water outlet of water-ring pump water circulating pump communicates with the water-in of water ring vacuum pump by pipeline, and the water-in of water-ring pump water circulating pump communicates with another water source.
Roots vaccum pump belongs to prior art, and it is the perfect positive-displacement vacuum pump of a kind of structure.Its great advantage is to have higher pumping speed under low inlet pressure, and can reach high relatively highest attainable vacuum.Because this pump is directly used in no relative movement contact between the major part of bleeding such as pump case, rotor and the end cap, thus this pump exercise performance stablize, long service life, maintenance cost is little.Roots vaccum pump can not use separately, and the forvacuum series connection of pumps must be arranged, just can start working when treating to be extracted into the inlet pressure that Roots vaccum pump can bear by forevacuum pump by the pressure in the system of taking out, otherwise will be because of overload and overheated the damage.In the utility model, forevacuum pump adopts water ring vacuum pump.Water-ring vacuum pump belongs to prior art, its principle of work is: inject a certain amount of water in its cylindrical pumping cylinder, the star impeller is contained in the pumping cylinder prejudicially, and when impeller rotated, water is thrown toward by centrifugal action and forms one all around was eccentric sealing water ring with respect to impeller.The gas that is sucked in the water-ring vacuum pump enters space between water ring and the impeller along air suction pipe and joint by suction opening, the right crescent part, because the rotation of impeller, this spatial volume is increased gradually by little, thereby produces vacuum take-off gas.Along with the rotation of impeller, gas enters left side crescent part.Because of impeller is eccentric rotation, this space dwindles gradually, and gas is compressed gradually and boosts, and gas and water are just entered in the water tank along vapor pipe through joint by the air outlet, is emitted by eduction pipe after separating automatically again.
The vacuum system that the utility model is formed with water ring vacuum pump and Roots vaccum pump replaces the steam-to-vacuum pump, reaches efficient and purpose of energy saving.For 1000L concentrating under reduced pressure still, configuration 2SK-3 type water ring vacuum pump is as backing vacuum pump, and ZJ-70 type Roots vaccum pump is as main vacuum pump.Working vacuum is 10kPa, and the two-stage (two-speed) pump power of motor is 8.6kw altogether.

Embodiment
Among Fig. 1, the concentrating under reduced pressure equipment in the tetrabromoethane production comprises concentrating under reduced pressure still 1, condenser 2, Receiving bin 3.Vacuum apparatus comprises Roots vaccum pump 5, lobe pump water circulating pump 8, water ring vacuum pump 6, water-ring pump water circulating pump 7, vacuum buffer groove 4 etc.
The inlet mouth of water ring vacuum pump 6 joins by the air outlet of pipeline and Roots vaccum pump 5.The water outlet of water-ring pump water circulating pump 7 communicates by the water-in of pipeline with water ring vacuum pump 6, the water-in of water-ring pump water circulating pump 7 joins by pipeline and water-ring pump circulating water pool 9, the water outlet of water ring vacuum pump joins by pipeline and water-ring pump circulating water pool, and this water can be recycled.
Vacuum buffer tank belongs to prior art.After even the effective constituent behind the concentrating under reduced pressure is extracted out by vacuum,, prevent to run material effectively because the effect of vacuum buffer tank can be collected in this vacuum buffer tank.
