Description
Technical field
The present invention relates to a kind of Coal dressing and cleaning technology and system, particularly a kind of brown coal vibration hot pressing dehydration process for upgrading and system.
Technical background
Energy and environment are important guarantees of national economy and social sustainable development.The year two thousand twenty, coal will be in 60% left and right in national energy consists of.The year two thousand fifty, the ratio of coal in China's primary energy source will account for 50% left and right.In the present explored brown coal retained reserve of China, the Northeast is maximum with the Inner Mongol, accounts for 3/4 of national brown coal retained reserve; Account for 1/5 of the whole nation take Yunnan Province as the brown coal reserves of main southwest.Brown coal are the minimum coals of degree of coalification, its principal feature is that moisture content is up to 30% ~ 50%, oxygen level is up to 15% ~ 30%, high-volatile content approximately 50%, the low 14MJ/kg that is about of calorific value, the humic acids that low ash smelting point, porosity be large, contain different quantities, chemical reactivity is strong, the characteristics such as poor heat stability have limited effective utilization of brown coal.Result of study shows, brown coal are after deliming dehydration upgrading processing, and its composition and character level off to bituminous coal, will more be conducive to utilize, transportation and storing, and has important environmental economy to be worth.
Current Domestic has been developed multiple dehydration process for upgrading abroad, mainly is divided into dehydration by evaporation and non-evaporating dehydrolysis two classes.Present dehydration by evaporation technology general using stack gas or other waste heat gas are drying medium, directly contact with brown coal its heating is made the moisture in coal evaporation drying, bring thus brown coal easily to pulverize, and product lump coal is lower; Because moisture removes with gaseous form, need to absorb the latent heat of vaporization, energy consumption is high; Because carrying out under atmospheric low-temperature, structure that can not permanent change coal also can absorb water rapidly in case be in wet environment, is unfavorable for depositing, long-distance transportation, later-stage utilization and processing.The non-evaporating dehydrolysis technology removes moisture in brown coal with liquid form, change the physics and chemistry structure of brown coal by high temperature and high pressure steam (or deep fat), makes it to be transformed into the dehydration method for upgrading of similar bituminous coal, has wide development potentiality.
At present the non-evaporating dehydrolysis technology comparative maturity of exploitation is that the hot pressing dewatering process (MTE) of propositions such as the Dortmund, Germany Strauss of university is comparatively ripe non-evaporating dehydrolysis technology, but still exist need to be higher temperature and pressure; Hot pressing dehydration is longer required action time, and production efficiency is low; Pressure is uneven in the coal charge axial distribution, the shortcomings such as the easy generation in the coal cinder middle part transverse breakage of moulding.On the whole, be subjected to the impact of condition, technology, material and economic dispatch factors, the brown coal dewatering process of efficient energy-saving also need further develop.
Summary of the invention
The objective of the invention is to provide a kind of brown coal vibration hot pressing dehydration process for upgrading and system, namely in brown coal upgrading dehydration, brown coal are carried out moulding, solve the problem that easily relapses after existing hot pressing dewatering pressure skewness and brown coal upgrading dehydration.
The object of the present invention is achieved like this: this brown coal vibration hot pressing dehydration upgrading comprises technique and device;
The process for upgrading step is as follows:
A) brown coal in run coal bin are crushed to through fan mill powder process pre-drying device and deliver to Pulverized Coal Bin below 3mm, through distribution device, brown coal are sent into vibration hot pressing dehydration device for improving quality, and are airtight after preheating;
B) pass into steam in vibration hot pressing dehydration device for improving quality, the heating brown coal are to technological temperature, and temperature is 150 ~ 220 ℃, and pressure is 5～12MPa; Steam and coal charge Direct Contact Heating that steam-generating installation produces, steam come from the steam of boiler generation, brown coal are vibrated hot pressing dehydration, moulding, the moulding static pressure is 5～12MPa; Vibration exciting force size, frequency can be regulated;
C) demoulding after dehydration, moulding, after moulded coal is cooling, send into finished bin, and the coal dust that produces when cooling is sent distribution device back to;
D) after the coal charge dehydration forming as the upgraded brown coal utilization, the moisture that removes utilizes preheating aftertreatment discharging through the preheating coal charge.
Device comprises: run coal bin, fan mill powder process pre-drying device, Pulverized Coal Bin, distribution device, vibration hot pressing dehydration device for improving quality, T-valve, waste water purification system, steam cock valve and steam-generating installation; The discharge port of run coal bin is connected with the feeding mouth of fan mill powder process pre-drying device, the discharge port of fan mill powder process pre-drying device is connected with the feeding mouth of distribution device with vibration hot pressing dehydration device for improving quality by Pulverized Coal Bin, the steam-in that steam-generating installation passes through steam cock valve and vibration hot pressing dehydration device for improving quality is connected, the water outlet of vibration hot pressing dehydration device for improving quality is by T-valve, and an end is connected with the entrance of vibration hot pressing dehydration device for improving quality; One end is discharged by waste water purification system.
Beneficial effect, owing to having adopted such scheme, in vibrating machine hot pressing dewatering process, under the synergy of vibration-static pressure-heat, brown coal can be under comparatively gentle processing condition, efficiently remove moisture in shorter action time, and form the coal cinder with some strength, and can effectively prevent from relapsing and spontaneous combustion, be convenient to store and transportation, and this process system is comparatively simple, processing condition easily realize, production process safety has good industrial applications prospect.
1. employing Vibrating Compacting System, coal charge is subject to the synergy of static pressure and exciting force, can effectively improve the transmission of pressure in coal charge, the coal charge pressure be distributed vertically more even, the pressure of avoiding the coal cinder after moulding to be subject to because of the middle part is little cause intensity low, transverse breakage occurs;
2. the effect of exciting force can be accelerated dehydration, the moulding of brown coal, shortens extrusion time, enhances productivity;
3. adopt saturation steam direct heating coal charge, saturation steam undergoes phase transition, discharges latent heat strengthens the heat exchange between itself and coal charge, and heat exchange efficiency is high, shorten heat-up time, and saturated steam obtains easily in industrial production;
4. coal is heated, and the physicals of water can change in rear ature of coal surface organo-functional group character and coal, and it is more hydrophobic that coal surface becomes, and the viscosity of water, density, surface tension reduce, and helps removing of water in coal;
5. under action of mechanical pressure, by means of extruding and pore volume reduce moisture is removed, the melting of wax and bituminous matter material also is beneficial to the carrying out of extruding;
6. the change of functional group's character and pore structure makes the coal cinder after dehydration forming effectively prevent from relapsing and spontaneous combustion;
7. moisture removes with liquid form, need not to absorb the latent heat of vaporization, and thermo-efficiency is high;
8. processing condition are gentle, and dewatering efficiency is high: 150 ~ 220 ℃ of temperature, and static pressure 5～12MPa, the water content of brown coal can be reduced to 10%.Solve the problem that easily relapses after existing hot pressing dewatering pressure skewness and brown coal upgrading dehydration, reached purpose of the present invention.
