Description

Efficient low-resistance gas-liquid plate type heat exchanger
Technical field
The utility model relates to a kind of efficient low-resistance gas-liquid plate type heat exchanger of gas and liquid heat exchange apparatus field.
Background technology
Appearance in modern society along with the social phenomenons such as scarcity of the pollution of environment and the energy, energy-conserving and environment-protective are subject to people's attention day by day, be similar to the gas that flue gas, the exhaust steam of boiler and give up " hot-air " etc. have higher temperature, directly to be discharged in atmosphere in the past, this has not only wasted the energy, has also polluted environment.Along with country, to the attention of " energy-saving and emission-reduction " with widely popularize, now just considering to reclaim the heat in these high-temperature gases by heat exchanger.When carrying out recuperation of heat, require heat exchanger to have: the characteristics such as resistance is little, corrosion-resistant, volume is little, otherwise can affect the normal operation of system and the service life of equipment.
At present domestic in the heat recovering process of high-temperature gas, generally adopt traditional tubular type or heat-pipe heat exchanger, this type of heat exchanger ubiquity is bulky, heat exchange efficiency is low, not corrosion-resistant, the shortcoming such as can't safeguard, in a lot of occasions, be subject to the restriction of the conditions such as the device space, corrosion and service life, can't well use, so a kind of special heat exchanger of market in urgent need, can substitute traditional heat exchanger.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies in the prior art, and my company is in analysis-by-synthesis and contrasted existing all kinds of heat exchanger, has developed efficient board-like gas-liquid heat-exchange, and a kind of efficient low-resistance gas-liquid plate type heat exchanger is provided,
The present utility model is achieved through the following technical solutions:
A kind of efficient low-resistance gas-liquid plate type heat exchanger, comprise the heat exchanger standard module, heat exchanger shell, the liquid pipeline of plugging into, detachable AD, the condensate discharge hole, adpting flange, the heat exchanger base, the heat exchanger standard module is positioned at heat exchanger shell, the heat exchanger base is positioned at the heat exchanger shell bottom, it is characterized in that: described heat exchanger standard module is the plate-sheet-type structure, make the comparison of resistance of gas little, arrangement regulation is arranged on flat board pad, can play the effect of flow-disturbing, strengthened heat transfer effect, the flat board of heat exchanger standard module is over against the adpting flange mouth, the heat exchanger standard module is by more than one or one, combining, modular assembling mode, the demand that adapts to the heat exchange amount by the quantity that increases or reduce module, very flexible, simultaneously, when a certain module breaks down, only needing to change separately module gets final product, and without changing whole equipment, liquid enters in the heat exchanger standard module by the entrance connecting pipe, and finally flow out from the outlet connecting pipe hydraulic fluid side of each heat exchanger standard module of flowing through, and gas flows through heat exchanger from a side flange direction of housing, flows out from an other side flange direction, detachable AD is arranged on heat exchanger shell, when some modules need to be safeguarded, can open AD, module is safeguarded separately or changed, the condensate discharge hole is arranged, be used to discharging condensed fluid on heat exchanger shell, the entrance of heat exchanger standard module interconnects by the entrance connecting pipe, is connected with the liquid pipeline of plugging into, the plate of heat exchanger standard module adopts 316 stainless steels, the shell material of heat exchanger is 304 stainless steels, and good corrosion resistance is arranged, in some special application, can be at the special anti-corrosion material of plated surface one deck of heat exchanger, can anti-strong acid, the corrosion of highly basic.
The utility model compared with prior art has following beneficial effect:
1. volume is little, is suitable for the installation and maintenance of narrow space;
2. heat exchange efficiency is high, good effect of heat exchange, and heat transfer coefficient reaches as high as 130W/m 2/ K;
3. acid-alkali-corrosive-resisting;
4. modular assembling mode, flexible;
5. heat exchanger cleans and is easy to maintenance;
6. the gas side resistance of heat exchanger is less, does not affect production technology.
The accompanying drawing explanation
Fig. 1 is efficient low-resistance gas-liquid plate type heat exchanger overall structure figure;
Fig. 2 is heat exchanger standard module construction figure.
In figure: heat exchanger standard module 1, heat exchanger shell 2, liquid plug into pipeline 3, detachable AD 4, condensate discharge hole 5, adpting flange 6 and heat exchanger base 7.
The specific embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
Be illustrated in figure 1 a kind of efficient low-resistance gas-liquid plate type heat exchanger, comprise heat exchanger standard module 1, heat exchanger shell 2, the liquid pipeline 3 of plugging into, detachable AD 4, condensate discharge hole 5, adpting flange 6 and heat exchanger base 7, this heat exchanger can be comprised of the module of many station symbols standard, the quantity of module depends on the field conditions such as heat exchange amount, heat exchanger shell wraps up the module sealing of standard, prevent that gas from leaking from the side, water or other liquid enter in heat exchanger by the entrance connecting pipe, the hydraulic fluid side of each module of flowing through, finally from the outlet connecting pipe, flow out.Meanwhile, the gas of high temperature flows through heat exchanger from a side flange direction of housing, from an other side flange direction, flow out, by heat exchanger module and the liquid that enters heat exchanger, carry out heat exchange, realize the effect of heat exchange, because the gas side of heat exchanger is essentially dull and stereotyped structure, make the comparison of resistance of gas little; Simultaneously, arrangement regulation is arranged on flat board pad, can play the effect of flow-disturbing, strengthened heat transfer effect, made the heat exchange efficiency of heat exchanger higher, the volume of heat exchanger is very little, it is 1/3 ~ 1/5 of conventional tubular heat exchanger, the plate of heat exchanger adopts 316 stainless steels, and the shell material of heat exchanger is 304 stainless steels, and good corrosion resistance is arranged.In some special application, can be at the special anti-corrosion material of plated surface one deck of heat exchanger, can anti-strong acid, the corrosion of highly basic, gas is shorter in the flow process of heat exchanger, makes the resistance of gas side less, and whole heat exchanger adopts modular theory, detachable AD is arranged on the housing of heat exchanger, when some modules need to be safeguarded, can open AD, module is safeguarded separately or changed.
