Description
Technical field
It the utility model is related to a kind of forcible entry of SCR catalyst recovery system, crushing, milling production line.
Background technology
China is an energy resource consumption big country based on thermal power generation, and substantial amounts of NO has been discharged while fire coalx.According to
Statistics, the NO in China 1998 and energy resource consumption relevant departmentsxDischarge capacity is 11.18 × 106Ton, wherein power department are 4.23
×106Ton, accounts for 37.9%；4.59 × 106 tons of industrial department, accounts for 41.0%；Communications and transportation 1.45 × 106Ton, accounts for 13.0%.In order to slow
Solve city NOxPollute, many city requirement solar obligation automobile exhaust purifiers, reduce the NO of communications and transportationxDischarge, this measure is
Make the NO of urbanxDischarge obtains certain containment；The NO of industrial department and power departmentxDischarge is mostly stationary source, relative to
Industrial department, the NO of power departmentxDischarge has amount is big to concentrate the characteristics of being easy to control.
Reduce NOxDischarge, have in combustion process control and burn after out of stock two ways, coal-burning power plant it is out of stock selection adopt
Use catalytic reduction method（SCR）Or noncatalytic reduction（SNCR）SCR denitration technology has denitration rate high（Maximum can be more than 90%）、
The advantages that selectivity is good, mature and reliable, is now widely used in thermal power station, is the main flow of coal unit denitration；SNCR denitration rate is not
Height, generally 30% ~ 40%.
In SCR device actual motion, many reasons are likely to that catalyst activity reduction, life-span can be caused to reduce.It is right
In the SCR catalyst of failure, in Japan, Eastern Europe, Germany, the U.S. and West Europe etc., country is general takes the method for first regenerating recycling
Processing, at present, the domestic recycling for honeycomb fashion SCR catalyst are still in the starting stage, are carried out without corresponding equipment
Processing.
The content of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of for the recovery, right of honeycomb fashion SCR catalyst
The forcible entry of honeycomb fashion SCR catalyst, the forcible entry of SCR catalyst recovery system of good crushing effect, crushing, milling production line.
The technical solution adopted in the utility model is：Broken including extruder, belt conveyor, sieving-washing machine, sedimentation basin, cage
Broken machine, agitator mill and cyclone；Described extruder discharging opening is connected by the charging aperture of belt conveyor and sieving-washing machine, sieve
Two discharging openings of washing machine are connected with sedimentation basin and cage crusher respectively, and cage crusher discharging opening is connected with the first kiln basin,
First kiln basin is connected by the charging aperture of Pulp pump and agitator mill, two discharging openings of agitator mill respectively with the first kiln basin
Connected with the second kiln basin, the second kiln basin is connected by the charging aperture of Pulp pump and cyclone, two discharging openings point of cyclone
It is not connected with the 3rd kiln basin and the first kiln basin.
In the forcible entry of above-mentioned SCR catalyst recovery system, crushing, milling production line, set in the first described kiln basin
There is agitating device.
In the forcible entry of above-mentioned SCR catalyst recovery system, crushing, milling production line, set in the second described kiln basin
There is agitating device.
Compared with existing artificial disassembling technology, the beneficial effects of the utility model are：
The utility model is simple in construction, compact, and floor space is small, can reduce production cost, and automaticity is high.This reality
Honeycomb fashion SCR catalyst is handled using closed loop forcible entry, crushing, milling mode with new, while taken before broken
Water sieve is washed, and is under wet broken and wet-milling operating mode during broken and milling, is ensured working site without harmful dust, not to human body and
Environment impacts, and disclosure satisfy that the needs of SCR catalyst recovery.
Brief description of the drawings
