Description
Technical field
The invention belongs to the flue gas desulfurization technique field, particularly a kind of purifier of ammonia type flue gas desulfurizing tail gas.
Background technology
In the flue gas that coal-burning boiler produces, sulfur dioxide is the main component that causes atmosphere pollution.Therefore, be to reduce pollution, need to adopt flue gas desulfurization technique to reduce the sulfur dioxide gas discharging environment, wherein ammonia flue gas desulfurization technique with desulfuration efficiency be higher than 95%, numerous advantages such as absorbent is prone to obtain and consumption is few and extensively being adopted.
This ammonia-process desulfurization technique also exists problems such as aerosol, the escaping of ammonia.Aerosol is to be disperseed and be suspended in the colloidal dispersion system that forms in the gas medium by solid or liquid fine particle, and its decentralized photo is solid or liquid fine particle, and its size is 0.01～10 micron.In ammonia flue gas desulfurization technique; Because the flue gas in the absorption tower contains saturation vapour; And be dissolved with ammonium sulfite and ammonium bisulfite composition in the steam, and temperature reduces very soon in atmosphere the time after flue gas goes out tower, and the steam that contains imonium salt in the flue gas condenses into droplet and particulate immediately; Be suspended in and form aerosol in the atmosphere, big drop can descend to ground.When flue gas passes through the impacting type demister in tower; Institute's droplets entrained is removed by major part in the flue gas; The steam that is gaseous state then can't be removed, and this kind steam has formed aerosol after going out tower exactly, directly through chimney it is entered atmosphere if do not add processing; To cause great influence to environment, seriously polluted.
At present, widely used baffle plate, silk screen, deflection plate, fiber mist eliminator etc. can not effectively solve the problem of aerosol, ammonia mist, and this also is that ammonia-process desulfurization technique fails to be used widely on the market now always, forms commercial-scale reason.
Summary of the invention
What the utility model will solve is the problems referred to above that exist in the ammonia type flue gas desulfurizing apparatus; Aim to provide a kind of ammonia type flue gas desulfurizing exhaust gas cleaner; Can effectively and easily control aerosol, the escaping of ammonia problem; Make the ammonia type flue gas desulfurizing technology on market, form commercial size, increase social environment benefit.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of ammonia type flue gas desulfurizing exhaust gas cleaner; Comprise the purifier body; Flushing nozzle and cooling water system is characterized in that being provided with in the said purifier body one group of cooling water pipe that is connected in series, and cooling water pipe outer surface row establishes the metal fin that is used for heat exchange; Above the purifier body, below be respectively equipped with some Flushing nozzles, cooling water system links to each other with Flushing nozzle with cooling water pipe respectively with water return pipeline through outlet conduit.
Said metal fin is processed by resistant material, fin shape bending in wave shape.
The peripheral wave-shaped fins of said water pipe is intervally arranged.
Said Flushing nozzle is located at polypropylene pipe one side.
This ammonia type flue gas desulfurizing exhaust gas cleaner can be installed on the desulfuration absorbing tower inner top, and promptly above the impacting type demister, flue gas goes out tower mouth below, also can be arranged on outside the absorption tower separately.When purifier was located in the tower, the condensing unit of being made up of waveform metal fin and cooling water pipe was covered with the desulfuration absorbing tower cross section; When purifier was separately set in outside the tower, the rounded or rectangle of the cross section of said purifier, purifier went out the tower mouth with absorption tower, flue gas and are communicated with.
Said flushing jet pipe is arranged on upper and lower two of exhaust gas cleaner body, it is characterized in that with the pipeline of polypropylene material manufacturing be contained in the numerous shower nozzles on the pipeline, regularly evenly wash dirt everywhere to exhaust gas cleaner base metal fin surface.
Said cooling water system comprises cooling water tank, water pump, and outlet conduit, water return pipeline, valve, flushing pipe and magnetic valve are supplied with exhaust gas cleaner body cooling water and flushing jet pipe wash water respectively.Cooling water tank is provided with height water stage measurement instrument, thermometer, water inlet pipe mouth, water pump interface and blowdown apparatus.
The ammonia type flue gas desulfurizing exhaust gas cleaner of the utility model, the water temperature during use in the major control cooling water tank is replenished cold water according to the requirement of setting, and discharges hot water simultaneously, keeps certain water yield.
Aerosol can controlled and reduce to the ammonia type flue gas desulfurizing exhaust gas cleaner of the utility model convenient, effectively.When flue gas passes through the impacting type demister in tower; Institute's droplets entrained is removed by major part in the flue gas, and the steam that is gaseous state then can't be removed, and this kind steam has formed aerosol after going out tower exactly; The exhaust gas cleaner that the utility model provided; Because its metal fin surface temperature is lower, the flue gas that contains saturation vapour will condense into droplet and particulate when contacting with fin, is bonded at the metal fin surface; Reach and remove the aerocolloidal purpose of part, the low more removal efficiency of metal fin surface temperature is high more.This purifier can suppress aerocolloidal formation on the source, reduce the moisture content in the flue gas simultaneously.
