Description
Technical field
The utility model relates to a kind of low vapour lock radial screw rod bundle demister, belongs to liquid foam in gaseous fluid and filters the gas-liquid separation technical field removed.
Background technology
In production daily at present, foam restricts the key issue that productivity promotes often, especially in high-salt wastewater process field hot greatly at present.When people use evaporation mode to carry out process discharge to waste water, once foam produces in a large number, and cannot deal carefully with, the solidifying water of production just can not reach the discharge standard of expection, and then whole vapo(u)rization system can be made to cancel.And traditional foam removal mode does not all overcome two problems always: the first, when using as the demister such as silk screen and cloth bag, the resistance brought to air-flow is quite large, and long-play meeting plug-hole; The second, when using as mechanical foam removers such as spiral boards, foam and rotary part contact surface very little, demister cannot blocking airflow cross section completely, cannot heavy-duty service.
Utility model content
According to above deficiency of the prior art, problem to be solved in the utility model is: provide a kind of structure simple, make easy to use, vapour lock is little, and foam fraction factor is thorough, and cost is low, is easy to the low vapour lock radial screw rod bundle demister safeguarded.
The utility model solves the technical scheme that its technical problem adopts:
Described low vapour lock radial screw rod bundle demister, comprise cylindrical shell, cylindrical shell bottom arranges air inlet, cylindrical shell top sets out gas port, cylinder body bottom arranges support and foam outlet, cylindrical shell top is by bracing frame fixed motor, the rotating shaft of motor is by transmission component connection for transmission axle, power transmission shaft penetrates into inner barrel from cylindrical shell top, seal is installed in the position that power transmission shaft contacts with cylindrical shell, be provided with in cylindrical shell with power transmission shaft with the use of power transmission shaft gripper shoe, power transmission shaft is installed screw rod bundle.
Described low vapour lock radial screw rod bundle demister drives power transmission shaft and screw rod bundle to rotate by the motor at cylindrical shell top, the power consumption of motor is mainly used for the friction work of bar bundle and tank body, therefore, changing according to the size for the treatment of capacity is different with the viscosity of material handling of motor power consumption, normal conditions.Treating capacity is larger, the more difficult separation of material, then require that the power of motor is larger, and turning to of motor will to promote being advisable in the direction that gas rises.The direction suppressing air-flow to rise is transferred to, to sacrifice low vapour lock to exchange for the foam removal effect surmounting design standard when overload operation.
Power transmission shaft mainly contains two effects, one is to screw rod bundle by power transmission, drive screw rod bundle to rotate and carry out foam fraction factor, another effect is fixing screw rod bundle, ensure the stability of screw rod bundle, the rotation mode of power transmission shaft can coordinate different driving members to arrange as required, and what power transmission shaft can be stable rotates in cylindrical shell, also connection for transmission annex can be set, can move up and down.
Screw rod bundle can effectively stop liquid film in air-flow, material can select pp (polypropylene), pe (polyethylene), pet (PET), pvc (polyvinyl chloride), pc (Merlon), polytetrafluoroethylene (PTFE) etc., the bar Shu Buyi of these materials is fractureed, and hardness is far below common metal material, the also high temperature of resistance to 60-100 DEG C, acid resistance and alkali resistance good.
Power transmission shaft gripper shoe effectively can maintain the stability of drive axis process, and seal can maintain intrasystem pressure, prevents gas leakage.Structure is simple, and make easy to use, vapour lock is little, and foam fraction factor is thorough, and cost is low, is easy to safeguard.
Preferred further, cylindrical shell arranged outside heat-insulation layer.Maintain the temperature of gas in tower, reduce barrel radiation.
Preferred further, the diameter of screw rod bundle is the 80%-150% of same level height barrel diameter, and the diameter of section of the single bar of screw rod bundle is 0.01mm-100mm.Enable screw rod bundle fully stop and absorb foam, when screw rod bundle correct rotation, to the gas effect of haveing a certain upgrade, the capacity loss that vapour lock causes can be made up further.
Preferred further, power transmission shaft gripper shoe at least arranges one, and power transmission shaft gripper shoe is fixed on inner barrel, and a bearing is installed in power transmission shaft gripper shoe centre position, and power transmission shaft is fixed in bearing.By the cooperation of power transmission shaft and bearing, can not rotational resistance be caused when power transmission shaft rotates, and effectively can maintain the stability of drive axis process.When material is without severe corrosive, power transmission shaft gripper shoe at least arranges one, has severe corrosive at material, common anticorrosion when cannot protect bearing, can not arrange power transmission shaft gripper shoe.
Preferred further, seal adopts packing seal or mechanical seal or magnet fluid sealing.Sealing means can be selected according to actual needs flexibly, can maintain intrasystem pressure, prevents gas leakage.
Preferred further, the length of power transmission shaft is the 20%-100% of integral device height.Ensure that power transmission shaft has enough length to be deep into cylindrical shell bottom, can effectively defoam.
Preferred further, screw rod bundle is arranged on the power transmission shaft between air inlet and gas outlet.Ensure foam removal effect.
Preferred further, the cross section of drum shaft is trapezoidal, triangle, rectangle, ellipse, circle, circular arc or its any combination.
Preferred further, heat-insulation layer is heat-barrier material, or passes into cold or thermal medium by coil pipe or chuck form.
The beneficial effect that the utility model has is:
1, the utility model can realize little vapour lock.The structure of screw rod bundle is as spiralling stair, and its levels space is ganged up, and can realize little vapour lock, and meanwhile, when bar bundle correct rotation, it has certain castering action to gas, can compensate for the energy loss that vapour lock causes further.Especially when bar footpath (0.01mm-1.5mm) is minimum, there is capillary effect between bar and bar, occur fluid-tight effect, whole bar bundle is approximately a spiral air pump, can realize little vapour lock.
2, the utility model can realize foam and is thoroughly separated.Screw rod bundle is fine and closely woven and many, and it is for the high adsorption capacity of foam, after multiple rotary is stacked, does not have foam therefrom to escape.And bar bundle not only can stop foam, centrifugal force can also be utilized to get rid of to perisporium by the drop in foam, bar bundle is in radial direction without any obstacles in addition, and whole process efficiency is high, can be good at the object solving foam fraction factor.
3, the utility model cost is low, makes simple and easy to maintenance.Because bar Shu Duoyong high molecule plastic makes, its cost several times lower than common metal demister cost, only needing during making spirals bar bundle bar is fixed on power transmission shaft, be far from metallic article making trouble, and after long-time use fouling, because bar Shu Benshen has pliability, only need to rub, even due to pliability itself, fouling can Automatic-falling after its formation.
