Description

A kind of deacidifying flue gas lime white purifier

Technical field

The utility model is related to field of environment protection equipment, specially a kind of deacidifying flue gas lime white purifier.

Background technology

In castoff burning processing procedure, the acid contaminants such as a large amount of sulfur dioxide, hydrogen chloride are will produce, and cause acid The pollutions such as rain also just need to carry out depickling to flue gas thus, and the acid stripping method of generally use is semidry process depickling at present, It is exactly using in lime white and principle, and there are solid large granular impurity in lime white, the abrasion to pipeline and atomizer is ratio Larger, service life of equipment can be not only influenced, can also influence the treatment effect of deacidifying flue gas, therefore the acid stripping method is to lime The quality requirements of slurry be it is relatively high, then lime white after entering continue equipment before pipeline in can generally be equipped with filter plant with Lime white is purified, the quality of lime white is improved, has basket filter or spin vibration sieve as filter device this generally use, still The impurity retained by filter can attach in the strainer of filter, and siltation is be easy to cause if long-time, also just needs people Work is frequently cleaned, and just compares energy consumption if using spin vibration sieve, and operating cost is high.

Invention content

In view of the above-mentioned problems, the utility model provides a kind of deacidifying flue gas lime white purifier, without frequent It is clear miscellaneous, it is not easy to plug, lime white good purification, operating cost is low, so as to reduce the abrasion to follow-up equipment, extends and uses Service life.

Its technical solution is such：It is characterized in that：It includes the purification pot, settling tank, cycle being sequentially connected by circulation Pump, the purification pot are equipped with lime slurry inlet, impurities outlet, lime white outlet, and the settling tank lower part is equipped with sewage draining exit, institute State and filter assemblies be housed in purification pot, the filter assemblies include the connection lime slurry inlet, impurities outlet screen pipe and Filter screen loaded on the screen pipe outside wall surface, lime white are described heavy along the screen pipe, settling tank, circulating pump closed cycle It is disposed with baffle plate in drop tank.

It is further characterized by：

The lime slurry inlet is set at the top of the purification pot, and the impurities outlet is set to the purification pot bottom, The lime white outlet is set to the purification pot sidewall, and the purification pot bottom is in inverted cone-shaped；

The filter assemblies further include guide housing, the first plate, the second plate, between first plate, the second plate Socket joint connects the screen pipe, and the guide housing is in funnel type, and is connect with first plate, and the neck of the guide housing is worn It crosses the lime slurry inlet with the circulating pump to be connected, described in the blowdown chamber warp that second plate is surrounded with purification pot bottom Impurities outlet is connected to the settling tank；

The screen pipe at least 11, filter opening on the filter screen is using the mesh of 20 mesh ~ 80；

The baffle plate horizontal spacing formula is arranged in the settling tank, and the baffle plate inclines along lime white flow direction Tiltedly, and angle of inclination is 60 ° ~ 80 °.

The utility model has the beneficial effects that lime white is flowed into from lime white import in screen pipe, satisfactory lime Slurry enters through filter screen in purification pot, and can be used as depickling by lime white outlet discharge and use, and contains impurity and bulky grain The lime white of insoluble matter enters by screen pipe and impurities outlet in settling tank, and lime white in settling tank flow bottom-up by side It is dynamic, and large granular impurity then can be arranged periodically by sewage draining exit by sedimentation pot bottom is settled down to after the blocking of baffle plate Dirt can mix new lime white and reenter in purification pot then after the lime white of baffle plate baffling is by recycling pumped, and It circulates, exists to the pollutant adhered on filter screen and wash away shear action, achieved the purpose that filter screen self-cleaning, to It without frequent clean filter screen, is not easy to block, lime white good purification reduces operating cost, and reduces to follow-up The abrasion of equipment, extends service life.

Fig. 2 is the structural schematic diagram of filter assemblies.

Specific implementation mode

As shown in Figure 1 and Figure 2, the utility model includes purification pot 1, settling tank 2, the circulating pump 3 that sequence is connected by circulation, only Change tank 1 and be equipped with lime slurry inlet 4, impurities outlet 5, lime white outlet 6,2 lower part of settling tank is equipped with sewage draining exit 13, purification pot 1 Interior that filter assemblies are housed, filter assemblies include being connected to lime slurry inlet 4, the screen pipe 7 of impurities outlet 5 and loaded on outside screen pipe 7 The filter screen of wall surface, lime white are disposed with baffle plate 8 along screen pipe 7, settling tank 2,3 closed cycle of circulating pump, settling tank 2.

Lime slurry inlet 4 is set to 1 top of purification pot, and impurities outlet 5 is set to 1 bottom of purification pot, and lime white outlet 6 is set It is placed in 1 side wall of purification pot, 1 bottom of purification pot is in inverted cone-shaped；Filter assemblies further include guide housing 9, the first plate 10, the second plate 11, socket joint connects screen pipe 7 between the first plate 10, the second plate 11, and guide housing 9 is in funnel type, and 9 bottom of guide housing is equipped with interior Screw thread, guide housing 9 are threadedly coupled with the first plate 10, and the neck of guide housing 9 is connected across lime slurry inlet 4 with circulating pump 3, Second plate 11 is connected to settling tank 2 with the blowdown chamber 12 that 1 bottom of purification pot surrounds through impurities outlet 5；Screen pipe 7 has 11, mistake Filter opening on strainer uses 30 mesh, and filter screen is stainless steel filtering net；It is disposed with two horizontally-arranged baffle plates 8 in settling tank 2, and often drains into Rare 7 pieces of baffle plates 8 are interlaced arrangement between the baffle plate 8 of two rows, and specifically, 8 horizontal spacing formula of baffle plate is arranged in In settling tank 2, baffle plate 8 is tilted along lime white flow direction, and angle of inclination is 70 °, can by the baffle plate 8 being obliquely installed Blocking large granular impurity well.
