Abstract
The utility model relates to an on-line descaling device for a micro-hydraulic turbine installed in a heat-transfer conduit. The micro-hydraulic turbine is installed in the heat-transfer conduit (4), and a blade (2) of a rotor of the hydraulic turbine is twisted on the surface of a wheel hub (1). When the fluid in the conduit flows, the hydraulic turbine operates by self. Because the rotor of the hydraulic turbine continuously brushes the conduit wall, scaling is difficult in the heat-transfer conduit. The existing scaling can also be removed, and the heat transferring is strengthened. The descaling device does not need additional power. When the velocity V in the conduit is larger than or equal to 0.06m/s, the hydraulic turbine can operate. The utility model has the advantages of reliable operation, large operating flexibility, good descaling effect, small fluid resistance, simple structure, convenient installation and obvious energy saving, and the utility model can be widely used for all kinds of new and old shell-and-conduit heat exchangers.
Description
The utility model belongs to apparatus for eliminating sludge field in heat transmission equipment, particularly the shell-and-tube heat transmission equipment pipe.
Scale removal to the shell-and-tube heat transmission equipment, at present major part still adopts the back of stopping to clean, and minority has adopted electromagnetism or ultrasound wave descaling effect unsatisfactory, drives the reciprocating online apparatus for eliminating sludge of conveyor screw and use such as rotation scraped surface, piston, need add power in addition, structure is also complicated; Also have a kind of coil spring (also claiming that spiral flow shakes) on-line cleaning method, weak point is that liquid in pipe need have high flow velocities (V＞0.4-0.8m/s) could turn round, and easily getting stuck, reliability is relatively poor.
The purpose of this utility model provides a kind of apparatus for eliminating sludge that power drive, energy online automatic desludging, reliable operation, making and operating cost are not high, can effectively remove the heat exchange in-tube fouling that do not need to add in addition.
The utility model is realized its purpose as follows: miniature fluid turbine is housed in heat exchanger tube 4, and the blade 2 of fluid turbine rotor is fixedly mounted on wheel hub 1 surface twist, and wheel hub is located on bearing support 3.
Apparatus for eliminating sludge of the present utility model has reached intended purposes fully in pilot production, not only fluid resistance is little, equipment moves under no dirty state all the time, anti-stifled ability is strong, and it is simple in structure, easy for installation, fluid turbine begins rotation and scale removal continuously voluntarily when liquid in pipe flow velocity V 〉=0.06m/s, and need not to add in addition power.After device of the present utility model is used for sugar refinery heater that heating tube reaches 3 meters, thoroughly change will stop in the 16 hours situation of 8 hours snakings of heater production run in the past, realized uninterrupted long-time running.This device can be widely used on the shell-and-tube heat-exchanger rig (containing heat exchanger, condenser, evaporimeter etc.) of all departments such as oil, chemical industry, sugaring, pharmacy, salt manufacturing, power, metallurgy, food, traffic, light industry and atomic energy.
Embodiment further specifies the utility model below in conjunction with accompanying drawing;
Fig. 1 is the structural representation that has used the online apparatus for eliminating sludge of the miniature fluid turbine of the utility model in single heat exchange tube.
In the inside of heat exchanger tube 4 by the miniature fluid turbine rotor of forming by wheel hub 1 and blade 2, the parallel installation of fluid turbine rotor with heat exchanger tube, blade is fixed on hub outside surface twist.Wheel hub can be hollowly also to can be solidly, and its end is the conical surface, sphere or plane and combination shape thereof, and the fluid turbine rotor bearing is on bearing support 3; Wheel hub among Fig. 1 has only the lower end to be supported frame 3 supporting, but also as required two ends all support.Blade is fixed on the wheel hub twist, and lead angle is decided according to working fluid character and technological requirement, can be 20 °-80 °.When liquid flows in heat exchanger tube, the rotating torque of liquid stream feeding turbine wheel drives the rotor rotation and the heat exchanging pipe internal surface is scrubbed, make to be difficult to fouling in the pipe, also can strike off, make heat transmission equipment in running, realize online scale removal, antiscale original fouling in managing.Because the rotation of fluid turbine rotor makes heat exchanger tube inner fluid viscous flow boundary layer constantly by disturbance, strengthened boundary layer heat transfer effectively simultaneously.Because of heat transmission equipment is not having under dirt, the few dirty state operation and strengthening heat transfer all the time, so thermal resistance is little, has improved heat transfer coefficient, plays a significant role to energy-conservation, is example with the cane sugar factories of 4000 tons of sugarcane/days, only at three mixed juice heaters (every heat-transfer area 160m
3) load onto miniature fluid turbine in the heat exchanger tube, make heater realize online automatic desludging, can save energy about 500,000 yuan through calculating every press for extracting juice season.
In the heat exchanger tube miniature fluid turbine to new, old heat transmission equipment all can be general.Both can be used for the technological transformation of original heat transmission equipment, achieved online automatic desludging and augmentation of heat transfer, but the novel heat exchange equipment of production online automatic desludging again.
Claims (3)
1. the interior online apparatus for eliminating sludge of manophyll turbine of heat exchanger tube is characterized in that in heat exchanger tube (4) miniature fluid turbine being housed, and the blade of fluid turbine (2) is fixed on wheel hub (1) surface twist, and wheel hub is gone up the location at bearing support (3).
2. apparatus for eliminating sludge as claimed in claim 1 is characterized in that wheel hub (1) is hollow.
3. apparatus for eliminating sludge as claimed in claim 1 or 2, the end that it is characterized in that wheel hub (1) are the combination shape of the conical surface and sphere.
