At conventional washing tower ruuning situation and result of use, each composition structure of scrubbing tower and material are carried out innovative design, adopt anti-fluorine, acid corrosion-resistant and aging-resistant fiberglass (FRP) housing, and adopt tower groove integral structure, reduce floor space, material usage and cyclic acid pump power consumption.At traditional porcelain or low, the yielding slump of polypropylene gas distribution grid percent opening, cracking, resistance is big, distribution of gas is uneven shortcoming, adopt novel SMO254 alloy sheets, alloy sheets has bar hole, and percent opening can reach (routine has only about 55%) more than 80%.Conventional tower cleaning solution distributor is shower nozzle or straight tube boring formula, few (18 points/m of separatory point
2), the separatory lack of homogeneity, cleaning dust efficient is low; Design novel superposition type cleaning solution distributor, separatory point can reach 42 points/m
2, divide acid more even.Adopt the regular or Haier's ring filler of ripple that novel specific area is big, porosity is high, make the abundant mass-and heat-transfer of flue gas and cleaning solution, adopt novel high spray point cleaning solution distributor simultaneously, so packed height is reduced to 2600mm, thereby has reduced tower body resistance (resistance is 0.6 times of conventional tower).For eliminating out tower band foam and droplet, baffling collision type demister is set at the top of tower, this is caught the foam device and adopts the polypropylene fibre structure of jumping the queue between the fiberglass deflection plate.Adopt the tower groove integral structure of low sizing height, and place on the ground, the circulating pump lift can reduce by 30%, thereby has reduced cleaning circulation pump power of motor and power consumption.
This project is by carrying out innovative design with washing liquid distributor, filler and height, gas distribution grid etc. in former scrubbing tower shell structure and material, the tower, simultaneously creatively add the new structure mist eliminator at cat head, cleaning dust, demist ability had both been improved, satisfy the cooling needs again, optimized production system configuration simultaneously again.Novel tower body is long-pending little, and floor space is few, cleaning dust cooling efficient height, and energy consumption is low, has realized sealing washing and sewage zero-discharge etc.The extensive approval and the praise of enterprises such as sulfuric acid, non-ferrous metal metallurgy, generating have been obtained.
Along with the increase of sulfuric acid, non-ferrous metal metallurgy and TRT, the high-efficiency and energy-saving type scrubbing tower is applied, and will drive the technological progress of relieving haperacidity, power industry.
Cleaning solution enters the cleaning solution distributor by after the circulating pump output after the cleaning solution cooler cools, enter the liquid collecting circulating slot behind corrugated regular filler or Haier's ring filler, gas distribution grid; Contain assorted flue gas through gas distribution grid, filler is reverse contacts with cleaning solution, carries out abundant mass-and heat-transfer, dedusting, lower the temperature after again through tower top catch the further foam removal of foam device, demist after go out scrubbing tower.
