Description
1. technical field
High-concentration coal sizing device is produced in a kind of organic wastewater with high concentration cleaning of the utility model offer, is related to the gasification of coal chemical industry
With burning and sewage disposal process.
2. background technology
High concentrated organic wastewater generally refers to be discharged by industries such as domestic garbage treatment plant, papermaking, leather, food and pharmacy
Containing COD 20000mg/L or more waste water.Containing a large amount of carbohydrate, fat, egg from matter, fiber in these waste water
The organic matters such as element can cause serious environmental pollution if direct emission.The main feature of high concentrated organic wastewater：First, having
Machine object concentration is high, and (for COD generally in 20000mg/L or more, some is even as high as 100,000 mg/L；Second is that complicated component (has in waste water
Machine object is in the majority with aromatic compound and heterocyclic compound, some contain sulfide, chloride, nitride and toxic organic compound)；
Third, coloration is high, there is peculiar smell (some waste water give out pungent stench).For a long time, high concentrated organic wastewater processing is always dirt
Problem in terms of water process annoyings the sound development of the industries such as petrochemical industry, coalification and medicine.According to statistics, national stone in 2013
The wastewater discharge for changing industry is 42 billion cubic meters, occupies the first place of each industrial department.Many enterprises due to environmental carrying capacity limitation,
Development receives restriction.
The development of China's COAL-WATER SLURRY TECHNOLOGY start from the 1980s, by 20 years of researches put into practice, have become compared with
For system, ripe technology.Water-coal-slurry is that coal dust (60-70%), water (30-40%) and a small amount of additive (1% or so) is mixed
After conjunction, ground, strong stirring forms it into the stream slurry of one water two-phase of coal to use as fuel or be closed for production of gasifying
At gas.Water-coal-slurry appearance is a kind of novel, low stain oil-substituted fuel like oil, good fluidity, and calorific value is about the half of heavy oil,
It has been applied successfully in the various industrial furnaces and boiler of the industries such as metallurgy, building materials, there is good development prospect.
If organic wastewater and fine coal or coke powder are mixed and made into water-coal-slurry, the high-temp combustion in gasification furnace or combustion furnace
(temperature is higher than 1300-1400 DEG C), the melting of organic matter high temperature or cracking can be made, generate the purifications such as water-gas, then transformed, desulfurization
Unstripped gas after process as synthesis ammonia.Using organic sewage production water-coal-slurry for gasifying or burning, waste water is not only realized
Environmental protection treatment, also waste water is made to have obtained recycling.
Under identical mobility, water coal slurry concentration is higher, due to discharge reduction, saves the gasification latent heat of a large amount of vapor
And sensible heat, no matter for gasification or combustion process, oxygen consumption has decline by a relatively large margin, gasification or efficiency of combustion to improve, generate
Preferable energy-saving effect.In addition when prepared by current sewage coal slurry, the higher wet type overflow type rod milling mechanism of energy consumption has usually been selected
Standby technique, i.e. coal sample of the granularity more than 10mm enter rod mill with pulping water, additive and grind slurrying simultaneously, but due to organic waste
Water is mostly that smell is larger, and conventional water-coal-slurry slurring equipment seal is poor, and distributing for exhaust gas is inevitable, is easy to periphery
Environment causes harmful effect, and the technique and energy-saving equipment technology of high-concentration sewage coal slurry are produced there is an urgent need for developing more clean environment firendly.
