Abstract
The utility model relates to a kind of desulfurization and assists slurry tank, is specially and arranges auxiliary slurry tank near desulfuration absorbing tower, is specially and arranges auxiliary slurry tank near desulfuration absorbing tower.Comprise auxiliary slurry tank main body, be provided with agitator and oxidation and aeration pipe in tower main body, auxiliary slurry tank adopts rubber-lined pipe to be communicated with absorption tower, and for improving the flexibility of system and convenient maintenance, the middle electrically operated valve that adopts cuts off.Configure the table meters such as liquid level gauge, densitometer, PH meter simultaneously.Compared with prior art, the utility model structure when reaching same desulfuration efficiency is simple, do not affect, and production cost is lower on existing equipment.
Description
Technical field
The utility model relates to power plant desulphurization system, is specially and arranges auxiliary slurry tank near desulfuration absorbing tower.
Background technology
Along with country is to the attention of environmental protection, stricter to power-plant flue gas discharge standard, design originally cannot meet the demands, in order to improve the desulfuration efficiency of power plant, market is transformed desulfuration absorbing tower, but reforming content is huger, causes cost higher, duration is longer, causes very large loss to power plant.
Utility model content
In order to meet fume emission requirement, make SO in flue gas
2discharge capacity reach national requirements, the utility model provides a kind of economical and practical simple method.The utility model makes full use of existing equipment, the basis not changing former desulfuration absorbing tower single unit system is done some transformations, thus improves desulfuration efficiency.
Technical problem to be solved in the utility model is: when former absorption tower, slurries cannot make SO in neat stress
2discharge capacity when reaching standard, needing to transform former absorption plant, an absorption tower be set nearby on absorption tower and assist slurry tank (capacity of slurry tank is determined according to amount of calculation), by calculating, making slurries amount enough absorb SO in flue gas
2, thus make SO
2discharge capacity is up to state standards.It mainly comprises: auxiliary slurry tank 1, agitator 2, rubber-lined pipe 3, electrically operated valve 4, oxidation fan 5, newly-increased spraying layer 6.
The advantage of this device is:
1, to single unit system not transformation, investment cost is low.
2, this new design theory is simple and practical.
3, arranged apart with former absorption tower device, structure is simple, does not affect other system.
4, slurries amount improves, and desulfuration efficiency improves obviously.
Accompanying drawing illustrates:
Fig. 1 assists slurry tank in a kind of absorption tower, wherein auxiliary slurry tank 1, agitator 2, rubber-lined pipe 3, electrically operated valve 4, oxidation fan 5, newly-increased spraying layer 6.
Detailed description of the invention:
Composition graphs 1, desulfurization assists slurry tank 1 to be positioned at vacant lot near former absorption tower, for filling fresh slurry, is communicated with absorption tower, is provided with agitator, aeration tube in auxiliary slurry tank.The casing of auxiliary slurry tank adopts scale material with anticorrosion.Auxiliary slurry tank agitator 2 adopts jacking-type, is provided with oxidation and aeration pipe 8 in case tank, and effect increases the slurries time of staying, improves the oxidation effectiveness of slurries in absorption tower.Auxiliary slurry tank 1 adopts rubber-lined pipe 3 to be communicated with absorption tower, for improving the convenient maintenance of the flexibility of system, adopts electrically operated valve 4 to cut off between auxiliary slurry tank and absorption tower.Configure the table meters such as liquid level gauge, densitometer, PH meter simultaneously.
Newly-increased 2 oxidation fan 5(mono-transport one standby) airduct one pass enter auxiliary slurry tank, a pass enters former absorption tower 7.Lime stone also can squeeze into auxiliary slurry tank based on lime stone slurry after transforming for slurry mode.
Under normal operating conditions, electronic stop valve 4 is opened, the slurry pool increased newly in auxiliary slurry tank and absorption tower forms linker, newly-increased serum recycle Pump Suction Nozzle is introduced from auxiliary slurry tank, slurries are thrown into newly-increased spraying layer 6, due to the effect of auxiliary slurry tank and the existence of newly-increased spraying layer, when former flue gas enters absorption tower, will with more slurry reaction, then SO in former flue gas
2discharge rate will greatly reduce, thus improve desulfuration efficiency.
Claims (3)
1. a slurry tank is assisted in desulfurization, and this slurry tank is positioned at vacant lot near former absorption tower, for filling fresh slurry, it is characterized in that described auxiliary slurry tank is communicated with absorption tower, is provided with agitator, aeration tube in auxiliary slurry tank.
2. slurry tank is assisted in a kind of desulfurization according to claim 1, it is characterized in that the casing of auxiliary slurry tank adopts scale material.
3. slurry tank is assisted in a kind of desulfurization according to claim 1, it is characterized in that adopting electrically operated valve and absorption tower to cut off in the middle of auxiliary slurry tank.
