Abstract
The invention provides an exhaust purification and discharge device in a stainless steel acid washing sludge treatment process. The device comprises an exhaust recovery tower and is characterized in that a spray device is arranged in the exhaust recovery tower and connected with a medicine supplying device, a wastewater recovery tank is arranged at the bottom of the recovery tower, and an inclined deposition plate is arranged in the wastewater recovery tank. Agents are sprayed to sufficiently react with smoke, sulfur dioxide and nitrogen oxide in exhaust, then the exhaust is washed and discharged, and produced sludge is deposited for producing chemical fertilizers and the like.
Description
technical field:
The present invention relates to the waste gas purification tapping equipment in a kind of acid-washing stainless steel sludge handling process, belong to three industrial wastes processing technology field.
background technology:
Stainless steel in cold rolling process, because pickling, grinding etc. can produce a certain amount of solid waste.The mainly mud, grinding mud etc. of pickling waste waters process formation.Containing chromium compound in mud, especially there is the Cr6+ ion of severe toxicity, therefore showing great attention to of the departments such as environmental protection is subject to, strict requirement is had to its process, the main method adopted is first by its harmless treatment at present, then antiseepage landfill disposal is done, because chromic toxicity is stronger, and can steady in a long-termly exist, antiseepage landfill thoroughly can not eliminate the harm that chromium causes environment, take valuable land resource, increase processing cost, also cause nickel simultaneously, the waste of the resources such as chromium, therefore, explore acid-washing stainless steel comprehensive utilization of mud to have great importance.
The processing method of the pickling mud that stainless steel enterprises relatively more conventional at present produces is, by forming final products aluminium ingot after the link such as air-dry, stirring, pressure ball, oven dry, batch mixing, sintering, melting after entering factory.Oven dry kiln and rotary kiln burning adopt natural gas to be fuel in this process, and the flue dust that burning produces, sulfur dioxide and nitrogen oxide, also will have dust to produce in oven dry, sintering circuit simultaneously.These fume emissions will cause very large pollution to air in atmosphere.
summary of the invention:
The waste gas purification tapping equipment provided for above-mentioned Problems existing in a kind of acid-washing stainless steel sludge handling process is provided, waste gas is guaranteed that waste gas rationally discharges after a series of process such as desulfurization, dedusting, avoids the environmental pollution caused.
Above-mentioned object is achieved through the following technical solutions:
Waste gas purification tapping equipment in acid-washing stainless steel sludge handling process, comprise waste gas recovery tower, spray equipment is provided with inside described waste gas recovery tower, described spray equipment connects drug delivery device, be provided with Sewage treatment pond bottom described recovery tower, inside described Sewage treatment pond, be provided with inclined settling plate.
