Description
Technical field
The present invention relates to drying plant technical field, particularly relate to method for designing and the device thereof of a kind of coal-fired drying unit
Technical field.
Background technology
For a long time, drying plant uses electrical heating or steam as the thermal source of drying plant always, and at thermal source
Course of conveying often configures multiple stage circulating fan, is allowed to finally still indirectly form hot blast and dries.This process is obvious
There is a large amount of waste energy and cause the shortcomings such as too much, the complex technical process of auxiliary device.And exist and be more difficult to solution
Technical problem is that, this thermal source needs higher temperature to be dried for those or toasts the engineering project of job requirements, then can not expire
Its technology using of foot requires.For these practical problems those skilled in the art by long-term production practices, by
Step is recognized and is only utilized hot blast could improve heat utilization efficiency and hot working effect to a greater extent as medium.And how to use
Fuel directly burns, and purified process forms hot blast, is dried with material Direct Contact Heating or toasts, used by this furnace drying method
Fuel Consumption about reduces about at least 50% than with steam-type or other indirect heaters.Therefore, drying product product are not being affected
In the case of matter, direct purification hot blast can be used completely.And under the guidance of this mentality of designing the technology of the art
Personnel design a series of coal-fired hot-blast stove, warm air oil furnace, fuel gas hot-blast stove etc.；Coal-fired hot-blast stove mainly includes: direct combustion
Formula coal-fired hot-blast stove, indirect type coal-fired hot-blast stove, separated type coal-fired hot-blast stove；Although coal-fired hot-blast stove is for meeting needs higher temperatures
Degree is dried or the engineering project of baking job requirements provides relatively reliable technical scheme, but current coal-fired hot-blast stove is still
There is following technological deficiency: dust contained in the flue gas of first coal-fired hot-blast stove and poisonous and harmful substance are still straight
Run in and put in atmosphere, air and environment are still being polluted and encroaching on；It is two owing to the exhanst gas outlet of coal-fired hot-blast stove is by cigarette
Chimney directly discharges in atmosphere, causes heat utilization efficiency to only reach about 70% at present, and the space that heat utilization efficiency saving is taped the latent power is very big.
Therefore, how to efficiently solve or reduce the discharge of poisonous and harmful substance contained in flue gas and the heat of raising coal-fired hot-blast stove
Efficiency, this is for from the point of view of those skilled in the art being still a technical task urgently to be resolved hurrily.
Content of the invention
