Description
Technical field
The utility model relates in the fluidized bed experimental study observing with the fluidisation basic data about the fluidized state of medium in the fluidized bed and obtains the field, relates in particular to the fluidizer that a kind of coal dust selection by winnowing is tested usefulness.
Background technology
Domestic iron and steel enterprises adopts traditional wet coal coking technology mostly at present; Basic technology is that several kinds of coal for cokings are broken by certain requirement, mixes the back more by a certain percentage and gets into coking by coke oven, and this technological advantage is a technology maturation; Simple to operate; But owing to contain 10% outside moisture approximately in the coal, cause the defective that is difficult to overcome below traditional wet coal coking technology existence: (1) productive capacity is low; This part moisture of evaporation need consume the plenty of time in process of coking, prolongs total coking cycle; (2) coke quality is difficult to guarantee, outside moisture will make the bulk density of coal reduce, and contact is not tight between the coal grain in process of coking, and the cohesive action of plastic mass is difficult for performance, therefore is difficult to obtain the high-quality smelter coke; (3) external water is divided through process of coking becomes coking chemical waste water, has increased carrying capacity of environment; (4) energy-output ratio is big, because the outside moisture of evaporation certainly will increase thermal energy consumption.
The selection by winnowing humidifying technology is the coking shove charge coal pre-service new technology that the pneumatic selection crushing technology of coking coal and moisture Control technology are integrated in one; It is to utilize the energy that blasts wind to make coal dust be in fluidized state that wherein pneumatic selection is pulverized; Height according to the coal dust buoyance lift is divided into some batches; The specific aim technology of different disposal in addition, so the fluidized state of coal dust more how and coal dust selection by winnowing basic data how accurately to obtain just to become the key of dealing with problems.
Summary of the invention
The purpose of the utility model provides the fluidizer of a kind of coal dust selection by winnowing experiment usefulness, and handled easily can clearly be observed the fluidisation situation of coal dust, solves the problem that coal dust selection by winnowing basic data is accurately obtained.
For solving the problems of the technologies described above, the technical scheme of the utility model is:
A kind of fluidizer of coal dust selection by winnowing experiment usefulness comprises streaming tank, air distribution plate and airduct, and airduct one end links to each other with the streaming tank bottom; Air distribution plate is located at airduct inlet top, streaming tank bottom, and the streaming tank top is provided with air outlet, and streaming tank stage casing, air distribution plate top is a fluidization regions; Said streaming tank is an organic glass matter; Tank skin one side of fluidization regions evenly is provided with the horizontal opening more than three from top to bottom, and opening part is provided with reverse leakproof rubber curtain, and the open side tank skin is provided with fixed support; Fixed support is provided with rotating shaft, and corresponding each opening is provided with and connects the coal flap in the rotating shaft.
The tank skin of said streaming tank is provided with pressure port, and pressure port is separately positioned between top, the fluidization regions bottom and air distribution plate of fluidization regions, between airduct inlet and the air distribution plate.
Compared with prior art; The beneficial effect of the utility model is: scheme is practical, technology accurately and reliably; Can obviously clearly observe the fluidisation situation of coal dust; Have easy to operate, data are accurate and characteristics such as visual, solved coal dust selection by winnowing basic data effectively and obtained problems such as difficulty.
