Description
Technical field
The present invention relates to flue gas waste heat recovery apparatus technical field, and in particular to a kind of gas cleaning and heat-exchange integrated dress
Put.
Background technology
Industrial Stoves can be divided into two classes by thermal regulation：One class is periodic kilns the kiln, is characterized in kiln Batch Process,
In each heating cycle, kiln furnace temperature is change；Equations of The Second Kind is continous way kiln, is characterized in that kiln is continuously produced, in burner hearth
Temperature section is divided, each section of temperature is kept essentially constant in heating process.Compared with continous way kiln, conventional between
The formula kiln of having a rest has the advantages that temperature increasing schedule is flexible, easily arranges production, but which has that maximum is that energy consumption is larger, mainly
It is accumulation of heat loss of thermal loss, heat loss that chemically incomplete combustion is caused and kiln lining that flue gas is taken away etc..To burn till temperature
As a example by the periodic kilns the kiln of 1800 DEG C of degree, through measuring and calculating, the heat loss that only high-temperature flue gas are caused with accumulation of heats such as kiln linings is just up to 50%,
Therefore, it is necessary to reduce the thermal loss that high-temperature flue gas are caused using flue gas waste heat recovery apparatus.
The feature of periodic kilns the kiln production technology determines that the flow of flue gas and temperature all have larger cyclic fluctuation, because
And causing the running environment rather harsh of waste-heat recovery device, it is desirable to which should adapt to changeable production status, stably may be used again
By ground operation.For the high-temperature dust-containing flue gas of periodic kilns the kiln, due to being limited by the material of cleaner and heat transmission equipment, at present
Using method be that then entering back into follow-up heat transmission equipment carries out heat exchange first by the water cooled cooling of flue gas that discharges.
There are problems in said method, for example, cooling water can be taken away amount of heat and cause energy loss, energy conversion time
Number excessively causes energy loss in the middle of heat transfer process etc., and the problem being particularly acute is that the method and device cannot make flue-gas temperature
It is maintained in a metastable scope, flue-gas temperature fluctuation not only causes huge Thermal-shock Damage to filter element, reduces
The service life of filter element, and export the energy after waste heat recovery to become unstable, it is difficult to effective profit is carried out to which
With.Therefore, the present invention needs a kind of gas cleaning of offer badly with heat-exchange integrated device to solve the problems, such as presently, there are.
Content of the invention
It is an object of the invention to proposing a kind of waste heat high efficiente callback for enabling flue gas, the less cigarette of energy loss
Gas is purified and heat-exchange integrated device.
Another object of the present invention is to propose a kind of high temperature fume dust removal heat exchange suitable for batch (-type) Industrial Stoves
