Description
Technical field
The utility model is related to a kind of fume-dehydrating field, more particularly to a kind of gas-liquid separation cylinder for fume-dehydrating,
And using the dehydration device and system of this gas-liquid separation cylinder.
Background technology
Coal-burning power plant is very big to water resources consumption amount.For the deficienter northern area of water resource, especially China
West area, coal-burning power plant need to make full use of water resource, constantly carry out energy-saving and water-saving ability and tap the latent power.Using more existing the coal-burning power plant
Limestone-gypsum wet flue gas desulfurization technology, this technology desulfuration efficiency is high, stable, wide in smoke gas treatment at home
It is general to use, but this method can consume substantial amounts of water, and a large amount of water droplets will be also carried in the flue gas after desulfurization, cause chimney periphery to go out
Existing rainfall phenomenon, this rainfall can cause corrosion to neighboring buildings and equipment, while also result in the waste of great lot of water resources.
For the moisture in recovered flue gas, chimney rain phenomenon is eliminated, is had in the prior art using the addition water conservancy diversion leaf in flue
The scheme of piece, using multiple guide vanes of arrangement, changes the direction of flow of flue gas, is passed through being changed into one after guide vane
" eddy flow ", using the centrifugal force of its generation, moisture therein is got rid of to inner wall of stack, along wall flow under discharge, flue gas prolongs flue
Continue to discharge.But the problem of this mode has certain, i.e., because the drop and the flue gas of motion of condensation are still within same sky
In, flue gas can produce " reentrainment " phenomenon to the drop of condensation, that is, the water removed again to taking away, so as to drop
The low recovering effect to water, the reason for causing the problem is that flue gas flow rate is high, and could not accomplish gas-liquid separation.
Prior art carries out flue gas direction change using multiple blades, also make it that equipment is complex, fault rate is relatively
Height, is unfavorable for the stable operation of equipment.
Utility model content
The purpose of this utility model is exactly current to that can not realize that gas-liquid separation is asked during moisture recovery in flue gas to solve
Topic can isolate condensate with flue gas, so that the problem of avoiding reentrainment there is provided a kind of gas-liquid separation cylinder.
Another purpose of the present utility model is then to provide a kind of dehydration device using gas-liquid separation cylinder, and the device was both
Existing multiple-blade guiding device can be used, also using the simpler guiding device of another structure, to reduce fault rate.
Further object of the present utility model is then to provide a kind of Separate System of Water-jet, and the system can be used for gas and moisture
Separation and gas with oil separation and recovery, so as to be conducive to the work of coal-burning power plant.
To achieve the above object, the utility model is adopted the following technical scheme that：
A kind of fume-dehydrating gas-liquid separation cylinder, it includes cylinder, and the barrel of the cylinder is provided with multiple openings, drop
It is thrown to after barrel by opening and cylinder body outer wall is transferred to by cylinder inboard wall, realizes the gas-liquid separation with flue gas.
When in use, the fluid machinery (such as pump or blower fan) generally with prime is used in combination, near wall pressure in cylinder
Power exceedes cylinder external pressure all the time, and source pressure forms dynamic pressure in the fluid machinery of backing system, wind blows, is arranged outside drop
One kind of pressure, the static pressure that where there is is also one of power for being arranged outside drop.
Wall spiral of the flue gas containing gas and liquid along cylinder, there is density contrast, liquid in gas and liquid
