Abstract
The utility model provides a kind of flushing water recycling system for potassium sulfate production, including flushing water collection groove, sedimentation basin, isolation tank, washing basin, water collect tank and scrubbing tower.The ground flushing water in relieving haperacidity area is collected, is reclaimed after treatment for scrubbing tower relieving haperacidity, so as to realize wastewater zero discharge, saving water resource and reduce production cost.
Description
Technical field
The utility model is related to a kind of flushing water recycling system for potassium sulfate production, more particularly to Mannheim proeess
Flushing water recycling system in potassium sulfate production.
Background technology
Mannheim proeess is current domestic the most ripe, most widely used production Technique of Potassium Sulphate, specifically refers to utilize chlorine
It is raw material single step reaction production potassium sulfate in mannheim furnace to change potassium and sulfuric acid.The advantage of the method is：The potassium sulfate quality of production
Preferably, have the disadvantage that reacting furnace production capacity is low, equipment corrosion is serious, energy consumption is big, and to consider storage and the fortune of by-product hydrochloric acid
Defeated problem.Into scrubbing tower washing after the containing hydrogen chloride furnace gas cooling that will be discharged in mannheim furnace in Mannheim proeess, SO is removed3Gas
The impurity such as body and most of dust, is absorbed with watery hydrochloric acid subsequently into film-falling absorption tower and technical hydrochloric acid is obtained.Wherein washing step
Great lot of water resources can be consumed, from saving water resource, the angle of reduces cost, because the main component of flushing water is water, chlorine
Change hydrogen and dust, therefore the flushing water on relieving haperacidity area ground can be collected, reclaim after treatment for relieving haperacidity, from
And realize wastewater zero discharge, environmental protection.
The content of the invention
The utility model discloses a kind of flushing water recycling system for potassium sulfate production, by relieving haperacidity area ground
Flushing water collect, reclaim after treatment, for scrubbing tower washing, relieving haperacidity step.Flushing water of the present utility model is returned
Receive includes flushing water collection groove, sedimentation basin, isolation tank, washing basin, water collect tank and scrubbing tower, the flushing water using system
The outlet connection sedimentation basin of collection groove, sedimentation basin connection isolation tank, isolation tank connection washing basin, washing basin is by water pump and returns
Flow tube connects water collect tank, water collect tank connection scrubbing tower.
Preferably, overflow pipe is set on water collect tank, is connected with isolation tank and washing basin.
Preferably, sedimentation basin, isolation tank and washing basin are connected as a single entity side by side.
Preferably, between sedimentation basin and isolation tank, between isolation tank and washing basin overfall is opened up, is set at overfall
Put screen pack.It is furthermore preferred that the overfall height of water level between sedimentation basin and isolation tank is higher than between isolation tank and washing basin
Overfall height of water level.
Preferably, it is respectively provided with control valve on return duct and overflow pipe.
Preferably, water collect tank is provided with flowmeter and control valve with the connecting tube of scrubbing tower.
Flushing water on ground flows into flushing water collection groove, is passed sequentially through by the outlet of flushing water collection groove
Sedimentation basin, isolation tank remove dust and impurity, subsequently into washing basin, when the water of washing basin savings reaches necessarily
During amount, the water pump and control valve of return duct are opened, the water in washing basin is pumped into water collect tank, the liquid level difference using water collect tank is passed through
Flowmeter enters scrubbing tower is used for relieving haperacidity.Water collect tank connects isolation tank and washing basin by overflow pipe respectively, when in water collect tank
When water exceedes the upper limit, in water meeting overflow to isolation tank and washing basin.
The beneficial effects of the utility model are：Flushing water recycles system in establishing Mannheim proeess process for producing potassium sulfate
System, it is possible to achieve no effuent discharge, while saving water resource, environmental protection.

Specific embodiment
The purpose of this utility model is realized with specific embodiment below in conjunction with the accompanying drawings, functional characteristics and advantage are done into one
Step explanation, but it is not used in restriction the utility model.
Collect recessed present embodiment discloses a kind of flushing water recycling system for potassium sulfate production, including flushing water
Groove, sedimentation basin, isolation tank, washing basin, water collect tank and scrubbing tower, the outlet connection sedimentation basin of the flushing water collection groove,
Sedimentation basin connects isolation tank, and isolation tank connection washing basin, washing basin connects water collect tank, water collect tank connection by water pump and return duct
Scrubbing tower, as shown in Figure 1.Sedimentation basin, isolation tank and washing basin are linked to be a rectangle side by side, and sedimentation basin and isolation tank share side
Pool wall, isolation tank shares side pool wall with washing basin, and two shared pool walls are parallel to each other.Overfall is opened up on pool wall is shared,
Overfall is rectangle, and the overfall height of water level between sedimentation basin and isolation tank is higher than the overfall between isolation tank and washing basin
Height of water level.
Flushing water on ground flows into flushing water collection groove, is passed sequentially through by the outlet of flushing water collection groove
Sedimentation basin, isolation tank remove dust and impurity, subsequently into washing basin, when the water of washing basin savings reaches necessarily
During amount, the water pump and control valve of return duct are opened, the water in washing basin is pumped into water collect tank, the liquid level difference using water collect tank is passed through
Flowmeter enters scrubbing tower is used for relieving haperacidity.Water collect tank connects isolation tank and washing basin by overflow pipe respectively, when in water collect tank
When water exceedes the upper limit, in water meeting overflow to isolation tank and washing basin.
Preferred embodiment of the present utility model is these are only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent structure or equivalent flow conversion done using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical fields, are similarly included in scope of patent protection of the present utility model.
