Description

A kind of spin chamber of novel multi-cavity rotating heat transfer equipment

Technical field

The utility model relates to heat transmission equipment technical field, relates in particular to a kind of spin chamber of multi-cavity rotating heat transfer equipment.

Background technology

Heat exchanger is can former source utilize requisite equipment in process, and day by day serious along with the development of modern new technology, new technology, new material and energy problem must bring the demand of more high-performance heat transmission equipment.The performance of heat exchanger plays an important role to the economy of product quality, capacity usage ratio and system and reliability, sometimes or even conclusive effect;

Heat exchanger mainly contains shell-and-tube heat exchanger and plate type heat exchanger, shell-and-tube heat exchanger mainly contains U-shaped pipe design and straight pipe type design, although having, the design of U-shaped pipe allow the fluid of pipe side and shell-side to have the larger temperature difference because the U-shaped pipe in housing can independence and freedom stretch, be suitable for take the advantage of the application of the domestic hot water that boiler water or steam are heat medium, but also exist due to U-shaped bending, pipe side liquid always flows along entire length is in parallel, this design is not suitable for the situation that temperature is close, in addition, owing to being U-shaped bend, when the dirtier or fouling of pipe side liquid, the whole limitation that can not be cleaned up completely, the application aspect of heavy dirt liquid or temperature difference existence is being processed in straight pipe type design, be suitable for, but the temperature difference is to occur in when the fluid heating drops to heat medium, outlet temperature between outlet temperature, due to straight tube assembly, tube bank can be moved and is convenient to pipe mechanical cleaning, but the form of tube sheet (fixing or unsteady) defines the ability of processing the larger temperature difference between fluid, the shortcoming of pipe heat exchanger is can not mechanical cleaning, pipe inconvenience changes, the heat output of unit capacity and unit mass is low, be applicable to the temperature difference large, the occasion that tube fluid Media Ratio is cleaner, once there is crack and corrosion, be difficult to eliminate, can only remove or change, maintenance cycle is long and expense is higher, helix tube has superior heat exchange property, but its manufacturing process is very numerous and diverse, plate type heat exchanger compact conformation, unpick and wash conveniently, heat transfer coefficient is high, adaptability is large, save material, but between plate, flow area is narrow, easily form incrustation scale and deposit, result in blockage, easy to leak during gasket seal poor heat resistance, spiral heat exchanger is because passage is narrower, on spiral plate, be welded with the setting post that maintains channel width, make mechanical cleaning difficulty.

Plate type heat exchanger has good heat exchange property, can adapt to economically the minimum operating mode of the temperature difference, it is mainly divided into plate and frame and plate-fin, the heat exchange efficiency of plate and frame is three to five times of other heat exchangers, even under the condition being close in the very little and cold and hot medium temperature of the temperature difference, operation conditions is desirable, herringbone on every block of plate or lambdoid ripple can produce high turbulent flow, high turbulent flow can reduce to minimum by deposition dirt, structure as an opening, plate type heat exchanger adds as required or reduces plate and carry out Optimal performance, and clean, maintenance, or easy to maintenance saving time, plate-fin does not have pad and heavy framework, and pad has been replaced (copper or nickel) by non-ferrous metal, and this has greatly increased it and has born the ability of pressure and temperature.Plate-fin heat exchanger significant difference is that design pressure can be up to 500 degrees Fahrenheits up to 450 pound per square inches and temperature, most plate fin heat-exchanging compact conformation, lightly, but it is to consider that plate type heat exchanger has some limitation, 300 pound per square inches are the highest actual design pressure, the gasket material that design temperature is used by heat exchanger determines, most widely used gasket material is butyronitrile, its temperature extremes is 230 degrees Fahrenheits, ethylene propylene diene monomer (ethylene propylene diene rubber) pad can be used under the condition up to 320 degrees Fahrenheits, the channel that adjacent plate is narrow has caused other restriction of plate type heat exchanger, when entering the fluid of plate type heat exchanger, there is SS or be subject to a large amount of ripples while affecting, screen pack should take in., in addition, narrow channel causes high turbulent flow, and this produces high pressure drop, under low pressure drop condition, makes plate type heat exchanger inapplicable.
