Abstract
The utility model discloses a can prevent desulfurization slurrying case that dust emits outward, including the limestone slurry case, the top of limestone slurry case is equipped with gas vent, feed inlet and water inlet, water inlet and pulping process water pipeline connection, the feed inlet is connected with the limestone flour storehouse that is located the top, a blast pipe is connected to the gas vent at the top of limestone slurry case, and this blast pipe bottom is hourglass hopper -shaped, the intraductal filter screen that is used for the separation dust that is equipped with, the filter screen top is equipped with the shower nozzle, and this shower nozzle and pulping process water pipeline connection are sprayed water when slurrying and is removed dust. This desulfurization slurrying case simple structure, dust removal effect is good.
Description
Technical field
This utility model relates to a kind of desulfurization slurrying case, particularly relates to a kind of desulfurization slurrying case preventing and emitting outside dust.
Background technology
In desulfurization pulping process, agstone is typically to be fallen into slurrying case by rotatory feeder valve, Weighing feeder from powder cabin again.Owing to powder is from high falling, and the granular size of limestone only has 0.063mm, easy airborne dust, produce relatively large dust in causing slurrying case and from air vent emits outlet, not only agstone consumption is big, also has a strong impact on that worker is healthy and surrounding health.
Utility model content
The purpose of this utility model is to provide the desulfurization slurrying case emitted outside the prevented dust of a kind of simple in construction.
The purpose of this utility model is achieved through the following technical solutions: a kind of desulfurization slurrying case preventing from emitting outside dust, including lime stone slurry case, the top of described lime stone slurry case is provided with air vent, charging aperture and water inlet, described water inlet is connected with pulping process water pipeline, described charging aperture is connected with limestone powder bin above, the air vent at the top of described lime stone slurry case connects an exhaustor, this exhaustor bottom is funnel-form, the filter screen for intercepting dust it is provided with in pipe, described filter screen is arranged over shower nozzle, this shower nozzle is connected with pulping process water pipeline, when slurrying, water spray carries out dedusting.
The mesh number of described filter screen is 100 mesh.
Described filter screen is disposed proximate to the position of funnel-form bottom.
For preventing because filter net jam causes water to overflow from exhaustor, this utility model can do following improvement: sets up overflow line, described exhaustor arranges overfall, on this overfall tube wall between filter screen and shower nozzle, the entrance point of shown overflow line connects overfall, its water side then extends to, in slurrying district melt pit, be emitted at this by water.
Pulping process water pipeline described in the utility model is set up the take-off line of a band valve and is connected to the upstream position of the pneumatic operated valve of pulping process water pipeline as dedusting dedicated water pipeline, the water inlet end of this take-off line, and its water side is connected with shower nozzle, supplies water for dedusting.
This utility model compared with prior art has the advantage that
1. this utility model arranges filter screen and shower nozzle in the exhaustor of the air vent at the top of lime stone slurry case; filter screen may filter that oarse-grained dust is stayed in slurry tank by it; shower nozzle then water distribution forms moisture film on filter screen and stops that little granule dust is through filter screen; thus be effectively prevented outside dust and emit; protect the health of operator and keep surrounding cleaning health, but also the consumption of limestone can be reduced.
2. this utility model simple in construction, only need to transform on the basis of original desulfurization slurrying case, small investment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The desulfurization slurrying case emitted outside prevented dust as shown in Figure 1 is an embodiment of the present utility model, and including lime stone slurry case 1, its top is provided with air vent 2, charging aperture 3 and water inlet 10.Water inlet 10 is connected with pulping process water pipeline 9, and charging aperture 3 is connected with limestone powder bin 11 above.The air vent 2 at the top of lime stone slurry case 1 is the preformed hole of DN100 flange reserved on lime stone slurry case 1, this air vent 2 connects an exhaustor 5, this exhaustor 5 bottom is funnel-form, the inherent position close to funnel-form bottom of pipe is provided for intercepting 100 mesh filter screens 4 of dust, filter screen 4 is arranged over shower nozzle 6, this shower nozzle 6 is connected with pulping process water pipeline 9, and when slurrying, water spray carries out dedusting.
Pulping process water pipeline 9 is set up the take-off line 7 of a band pneumatic operated valve and is connected to the upstream position of the pneumatic operated valve of pulping process water pipeline 9 as dedusting dedicated water pipeline, the water inlet end of this take-off line 7, and its water side is connected with shower nozzle 6, supplies water for dedusting.For preventing because filter net jam causes water to overflow from exhaustor 5, arranging overfall on exhaustor 5, on this overfall tube wall between filter screen 4 and shower nozzle 6, the entrance point of overflow line 8 connects overfall, its water side then extends to, in slurrying district melt pit, be emitted at this by water.
This utility model can be summarized with other the concrete form without prejudice to spirit or essential characteristics of the present utility model.Above-described embodiment of the present utility model all can only be considered to illustrate and not limit of the present utility model, every any trickle amendment, equivalent variations and modification made above example according to substantial technological of the present utility model, belongs in the range of technical solutions of the utility model.
