Abstract
The invention discloses a device for sorting clean coal with different particle sizes, and belongs to the technical field of clean coal sorting. The device comprises a fluidization tank. A coaling barrel is arranged at the top of the fluidization tank, and an air inlet pipe is arranged at the bottom of the fluidization tank. A steam pipe is arranged on one side wall of the fluidization tank, a plurality of coal taking plates stretching into the fluidization tank are arranged on the other side wall of the fluidization tank, and a pressure gauge and a plurality of thermometers are further arranged on the side wall, with the coal taking plates, of the fluidization tank. The device is used for sorting clean coal with different particle sizes by means of the thermophoresis effect, steam and air can be mixed in the fluidization tank, and a concentration gradient is formed in the height direction of the fluidization tank under crossing mixing of steam and air; and due to the fact that the amounts of air included in steam in different height directions of the fluidization tank are different, the temperatures of mixed gas are different. Coal particles with different particle sizes are fed into the coaling barrel, the coal particles are in a suspended state in distribution of temperature gradually decreasing in the height direction of the fluidization tank, and the thermophoresis phenomenon is achieved under the action of the concentration gradient. The device is reasonable in structural design and easy to implement, and energy saving and environment protection are achieved.
Description
Technical field
The invention belongs to cleaned coal sorting technology field, relate to a kind of device of sorting different grain size cleaned coal.
Background technology
China is coal consumption big country, in order to the sustainability realizing energy-conserving and environment-protective and coal uses, improves the quality of coal product and the economic benefit of coal consumers.In steam coal process, the core of Coal dressing is coal separation.The devices such as existing coal jigging and inclined trough washing coal can be divided elect as bulk, middle piece, fritter, beans etc., meet the requirement of different user to coal cinder granularity, further the sorting of varigrained coal grain must use sieve, screening not only causes artificial consumption, and uneven coal grain also can cause the heat absorptions such as burning, pyrolysis irregular, is necessary to adopt effective method more to carry out sorting more accurately to different grain size coal grain.
Summary of the invention
The object of the present invention is to provide a kind of device of sorting different grain size cleaned coal, this apparatus structure is reasonable in design, easily realizes, and effectively can to solve in prior art coal particle size in coal washing process and distinguish coarse problem.
The present invention is achieved through the following technical solutions:
A device for sorting different grain size cleaned coal, comprises streaming tank, and be provided with coal cylinder at streaming tank top, bottom is provided with air inlet pipe; Be provided with steam pipe at a sidewall of streaming tank, another sidewall be provided with some stretch into streaming tank inside get coal plate, be also provided with Pressure gauge and some thermometers arranging on the streaming tank sidewall getting coal plate.
Preferably, described in get coal plate be two, be respectively from top to bottom arrange first get coal plate and second and get coal plate.
Preferably, thermometer is also two, is respectively to be arranged on first and to get the first thermometer above coal plate, and is arranged on second and gets the second thermometer above coal plate.
Air inlet pipe end is connected with blower fan, and air inlet pipe is also provided with intake valve and flowmeter.
Steam pipe is also provided with steam valve.
Compared with prior art, the present invention has following useful technique effect:
The device of sorting different grain size cleaned coal disclosed by the invention, thermophoretic effect is utilized to carry out sorting to varigrained cleaned coal, a sidewall of streaming tank is provided with steam pipe, air intake duct pipe is provided with bottom streaming tank, can respectively to importing steam and air in streaming tank, in the intersection immixture of steam and air, form concentration gradient along streaming tank short transverse, because air capacity contained in the steam on streaming tank differing heights direction is different, the temperature of mist is also different.Varigrained coal grain is fed in coal cylinder, in the Temperature Distribution declined gradually along streaming tank short transverse, coal grain presents suspended state, thermophoresis phenomenon is realized under concentration gradient effect, show as granule coal dust and be distributed in lower floor, large beans powder is distributed in upper strata, gets coal plate, varigrained cleaned coal rationally can be separated by be arranged on streaming tank sidewall some.This apparatus structure is reasonable in design, easily realizes, and energy-conserving and environment-protective, effectively can to solve in prior art coal particle size in coal washing process and distinguish coarse problem.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1 is steam pipe; 2 is steam valve; 3 is streaming tank; 4 is coal cylinder; 5 is first get coal plate; 6 is second get coal plate; 7 is intake valve; 8 is air inlet pipe; 9 is blower fan; 10 is Pressure gauge; 11 is the first thermometer; 12 is the second thermometer; 13 is flowmeter.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
See Fig. 1, the device of sorting different grain size cleaned coal disclosed by the invention, comprises streaming tank 3, and be provided with coal cylinder 4 at streaming tank 3 top, bottom is provided with air inlet pipe 8; Be provided with steam pipe 1 at a sidewall of streaming tank 3, another sidewall be provided with some stretch into streaming tank 3 inside get coal plate, be also provided with Pressure gauge 10 and some thermometers arranging on streaming tank 3 sidewall getting coal plate.Air inlet pipe 8 end is connected with blower fan 9, air inlet pipe 8 is also provided with intake valve 7 and flowmeter 13, steam pipe 1 is also provided with steam valve 2.
Preferably, getting coal plate is two, be respectively from top to bottom arrange first get coal plate 5 and second and get coal plate 6; Thermometer is also two, is respectively to be arranged on first and to get the first thermometer 11 above coal plate 5, and is arranged on second and gets the second thermometer 12 above coal plate 6.
The device of sorting different grain size cleaned coal of the present invention, in use:
First open steam valve 2, be sent to streaming tank 3 by steam from steam pipe 1, air to be drawn in air inlet pipe 8 by blower fan 9 and to be fed in streaming tank 3, and varigrained cleaned coal is sent into streaming tank 3 from the top of coal cylinder 4 simultaneously.Coal grain is in suspended state under the blowing of steam and air, distribute in the thermograde effect lower leaf along streaming tank height, the Pressure gauge that streaming tank is installed by differing heights and the first thermometer 11 and the second thermometer 12 can record the distribution of streaming tank 3 pressure and temperature simultaneously.Simultaneously get coal plate 5 and second along first of streaming tank 3 differing heights directional spreding to get coal plate 6 and be used for varigrained coal to take out in streaming tank 3.
This device adopts thermophoretic effect sorting different grain size cleaned coal, steam and air can be utilized to mix in streaming tank, concentration gradient is being formed along streaming tank short transverse under the intersection mixing of steam and air, because air capacity contained in the steam on streaming tank differing heights direction is different, the temperature of mist is also different.Varigrained coal grain is fed to and adds in scuttle, in the Temperature Distribution declined gradually along streaming tank short transverse, coal grain presents suspended state, realizes thermophoresis phenomenon under concentration gradient effect, show as granule coal dust and be distributed in lower floor, large beans powder is distributed in upper strata.
