Abstract
Description
Technical field
This utility model belongs to environmental technology field, especially a kind of wet classification dust arrester, and the device can be used to contain In the process of cloud of dust gas.
Background technology
Recent years, wet scrubber is so that its simple structure, equipment investment be low, efficiency of dust collection is high in coal-burning boiler, chemical industry system The industries such as medicine, food processing, metallurgy, casting have obtained widely applying.Wet scrubber is gone back while powder dust particle is removed The gaseous contaminant in gas can be removed, has not only been played a part of dedusting but also has been played a part of purification.With electrostatic precipitator and bag Formula cleaner unit is compared, and wet scrubber can process high temperature, high wet gas current and inflammable and explosive dusty gas.But, pass The single wet scrubber efficiency of dust collection of system is relatively low, it is impossible to meet the standard of national requirements for environmental protection discharge.
By retrieval, such as the next chapter patent publication us related to present patent application are found：
Flue gas wet classification dust arrester (CN103276141A) of converter, including the thick dedusting dress of one-level being sequentially connected Put, two grades of smart dust arresters, three-level essence dust arrester, blower fan and circulations, the thick dust arrester of the one-level is provided with spray Device I and mud discharging valve I, described two grades smart dust arresters are provided with spray equipment II and mud discharging valve II, the recirculated water System includes sewage-treatment plant and circulating pump, the mud discharging valve I and mud discharging valve II respectively with sewage-treatment plant Entrance connects, and the sewage-treatment plant outlet is connected respectively by circulating pump with spray equipment I and spray equipment II.This practicality New structure is simple, stable and reliable operation, invests less, and operation expense is low.By 3-stage dust-removal, dedusting effect is improve Rate, it is ensured that the dust contained flue gas concentration≤10mg/m discharged after purification3, less than existing dry dedusting technology and wet dedusting skill Art level, its discharge standard reaches International Environmental Protection standard.
By contrast, there are the different of essence in this utility model patent application from above-mentioned patent publication us.
Utility model content
The purpose of this utility model is to overcome the weak point in existing wet dust collection technology, there is provided a kind of wet classification Dust arrester and application, the device can ensure that the concentration of emission of outlet flue dust is 5mg/Nm3Hereinafter, national requirements for environmental protection is reached The standard of discharge, the device can be used in the process of ash-laden gas.
The purpose of this utility model is achieved through the following technical solutions：
A kind of wet classification dust arrester, described device includes crust of the device, the thick dust arrester of one-level, two grades of smart dedusting dresses Put, spray system, demister system, gas outlet and cistern system, the thick dust arrester of the one-level is arranged at the bottom of crust of the device, The gas outlet is arranged at the top of crust of the device, and from the bottom to top successively interval sets for described two grades smart dust arresters, demister systems On the crust of the device being placed between the thick dust arrester of one-level and gas outlet, the spray system can be to two grades of smart dust arrester sprays Drench, the cistern system is arranged at outside crust of the device and the setting that is connected with the thick dust arrester of one-level；
The thick dust arrester of the one-level includes air inlet, sleeve expansion piece, flue gas nozzle, dust storage chamber I, collection QI KOU, described Dust storage chamber I is arranged at the bottom of crust of the device, and in the dust storage chamber I water is loaded with, with dress on the crust of the device above dust storage chamber I Put shell and be connected and be provided with air inlet, the tail end of the air inlet connects the upper of flue gas nozzle by the sleeve expansion piece being coaxially disposed End, the bottom of the flue gas nozzle is arranged at the ullage of dust storage chamber I, and the flue gas nozzle can spray the impact water surface to liquid level Flue gas, the crust of the device above the air inlet is provided with collection QI KOU, the bottom outer-edge of the collection QI KOU and the inwall of crust of the device It is sealingly disposed in together；
The cistern system includes water tank regulating valve, slush pump, settling tank and 1# water circulating pumps, the dust storage chamber I's Bottom is connected setting by water tank regulating valve, slush pump with the side entrance of middle and upper part one of settling tank, in the settling tank Another side outlet in top is connected setting by 1# water circulating pumps with dust storage chamber I, and the 1# water circulating pumps can be by settling tank Water input dust storage chamber I in；
Described two grades smart dust arresters include discharge pipe, dirt pocket, cross smoke pipeline, dust storage chamber II, filler plate and header tank, The top of the collection QI KOU arranges header tank, and the header tank is not attached to logical setting with dust storage chamber I, and the top of the header tank arranges collection Dirt room II, between dust storage chamber II and header tank filler plate is coaxially disposed, and the edge of the filler plate is close with the inwall of crust of the device Envelope is set together；The top of dust storage chamber II arranges dirt pocket, and the top outer rim of the dirt pocket is tight with the inwall of crust of the device Close to be set together, the coaxial close communication in bottom of the dirt pocket arranges discharge pipe, bottom outside edge and the dress of the discharge pipe The inner wall sealing for putting shell is arranged, and the outlet at bottom of the discharge pipe is connected setting with dust storage chamber II；The dirt pocket middle and lower part Side close communication arranged the top of smoke pipeline, and it is tight with the top of collection QI KOU that the bottom for crossing smoke pipeline is passed down through filler plate The close setting that is connected；
The spray system includes 2# water circulating pumps, spray regulating valve, spray pipeline and ultrasonic wave atomizing nozzle, the 2# The input of water circulating pump is connected setting with the bottom of header tank, the outfan of the 2# water circulating pumps by spray regulating valve with Spray pipeline is connected setting, and uniform interval is connected and is provided with multiple down-set ultrasounds on the bottom surface of the spray pipeline Ripple atomizer；The spray pipeline and ultrasonic wave atomizing nozzle are arranged at intervals at outside the device between dirt pocket and demister system On shell, the ultrasonic wave atomizing nozzle can spray fine water-spray to dirt pocket.
And, described device also includes air-introduced machine, and the air-introduced machine is connected setting with gas outlet, and the gas outlet passes through to draw Blower fan carries out outlet.
