Description
The present invention relates to a kind of drying equipment, especially the largest particles is handled less than the oven dry of 50mm raw coal, be particularly suitable for drying plant as each large, medium and small type thermal power plant to particulate material.
At present, the drying equipment kind of domestic use is a lot, wherein uses maximum three classes that have: the one, and horizontal vibrating dryer, the 2nd, multilayer vibrating desiccator in horizontal circle movement, the 3rd, screw-casing cartridge type circular vibration drying machine.Their advantage is that machine works is steady, and applicable surface is wider, but the common drawback that exists is: 1, all need vibrating mechanism, equipment investment is big; 2, because general drying equipment volume and weight is all big, realize vibration, require power of motor big, power consumption is big; 3, because drying equipment constantly vibrates, and sieve plate easily comes off, service life is short.And in the thermal power generation industry, special equipment to the coal dust oven dry generally all adopts the horizontal spiral oven dry, being about to hot blast feeds in the horizontal cylinder, utilize the coal plate coal dust upset oven dry, the major defect that this drying mode exists: the one, drying mode is science not, and the coal seam seldom can be subjected to baking in the heat in the front in switching process, coal plate upset number of times wants many, have a big chunk hot blast to waste, the hot blast utilization rate is not high, and energy consumption is big; The 2nd, need high power motor and corollary equipment, complex structure, equipment investment is big.
The objective of the invention is in order to overcome above-mentioned the deficiencies in the prior art, propose a kind of simple in structure, reliable operation, drying effect is good and does not need the novel high-efficiency and energy-saving drying unit of vibrating mechanism.
Realize the technical scheme of above-mentioned purpose: a kind of energy-saving efficient baker, comprise cylindrical shell, distributing device, the multilayer support, the cone-shaped of abscissusing oven dry body and hot blast distributor pipe, the cylindrical shell top is equipped with exhausting duct, abscissus cone-shaped oven dry body and the inversion that on each layer support, is fixed with into the up-down structure cone-shaped oven dry body of abscissusing, the following circle of the cone-shaped of abscissusing oven dry body stretches in the upward circle of being inverted the cone-shaped oven dry body of abscissusing, every layer of round last layer that stretches into of the going up of cone-shaped oven dry body of abscissusing is inverted in the following circle of the cone-shaped oven dry body of abscissusing, between the circle annular feed opening is arranged up and down, the hot blast distributor pipe passes the center of respectively drying body, and the upper section place at the cone-shaped oven dry body of respectively abscissusing has annular hot blast supply port, and top layer is abscissused and settled distributing device on the cone-shaped oven dry body.
The cone angle of the cone-shaped of abscissusing oven dry body is 42～47 degree, and the vertical height of annular feed opening is 60～80mm, and the length of the effective conical surface of oven dry body is 80～120mm.
The cone angle of the cone-shaped of abscissusing oven dry body is 45.3 degree, and the vertical height of annular feed opening is 71mm, and the length of the effective conical surface of oven dry body is 100mm.
The multilayer support is 36 layers.
Coal feeder is a sphere shape distributing device.
There is the infundibulate feeder bottom cone-shaped oven dry body below of abscissusing.
Adopt the drying unit of above-mentioned new structure, compared with prior art, its advantage is: 1, cancelled vibrating mechanism; 2, simple in structure, cost of manufacture is low; 3, drying mode is scientific and reasonable, only need granular material is risen to the top of drying unit, material just the ground of the conical surface one-level one-level in the drying unit toward current downflow, in process of flowing, so the material bed positive air cooking of accepting from bottom to top is good drying effect, energy savings greatly, 4, because friction mechanism is not prone to obscission, reliable operation.In sum, this device can be realized purpose of the present invention fully.
Below in conjunction with accompanying drawing in detail its structure is described in detail:
Fig. 1 is a kind of structure of the present invention (analysing and observe) figure.
Embodiment: with reference to accompanying drawing 1, a kind of energy-saving efficient baker, mainly by cylindrical shell 7, sphere shape coal feeder 1, multilayer support 6, the cone-shaped of abscissusing oven dry body 3, be inverted abscissus cone-shaped oven dry body 4 and hot blast distributor pipe 8 and form.Abscissus cone-shaped oven dry body 3 and the inversion that on each layer support 6, is fixed with into the up-down structure cone-shaped oven dry body 4 of abscissusing with support bar 5, the cone angle of frusto-conical surface shape oven dry body is α, the design of cone angle guarantees that flowing naturally of material be advisable.The following circle of the cone-shaped of abscissusing oven dry body 3 stretches in the upward circle of being inverted the cone-shaped oven dry body 4 of abscissusing, every layer of round last layer that stretches into of the going up of cone-shaped oven dry body 3 of abscissusing is inverted in the following circle of the cone-shaped oven dry body 4 of abscissusing, between the circle annular feed opening 2 is arranged up and down, the vertical height of annular feed opening 2 is H, and guaranteeing has enough stoving times in dropping process.The length L that the coal breakage of vertical height H is put next annular feed opening 2 is effective conical surface length, and effectively conical surface length L also should guarantee flowing naturally of material.There is hot blast distributor pipe 8 to pass respectively to dry the center of body (3,4), and the upper section place at the cone-shaped oven dry body 4 of respectively abscissusing has annular hot blast supply port 13, top layer is abscissused and is fixed with spherical coal feeder 1 on the cone-shaped oven dry body 3, the top of cylindrical shell 7 is equipped with exhausting duct 12, the below of cylindrical shell 7 has hot blast import 9, the following circle that bottom is inverted the cone-shaped oven dry body 4 of abscissusing is a discharging opening 10, and there is infundibulate coal powder collection groove 11 below of discharging opening 10.
In this device, should guarantee that coal dust can be along the positive and negative conical surface one-level one-level ground in the drying unit naturally toward current downflow, guarantee again in process of flowing, the material bed positive enough time of accepting air cooking from bottom to top, the design of the cone angle of the cone-shaped of abscissusing oven dry body 3 is very key, for as the oven dry special equipment before the coal pulverizer of thermal power plant, the cone angle of the cone-shaped of abscissusing oven dry body is 45.3 degree, the vertical height H of annular feed opening is 71mm, the length L that the oven dry body is effectively dried the conical surface is 100mm, and support is 36 layers.
For variable grain size, humidity, viscosity and baking requirement, can suitably adjust above-mentioned various parameter, wherein cone angle is 42～47 degree, and the vertical height of annular feed opening is 60～80mm, and the length that the oven dry body is effectively dried the conical surface is 80～120mm.
