A kind of tubular type electro-conductive glass wet electrical dust precipitator
Technical field:
The utility model relates to industrial dedusting equipment technical field, particularly relates to a kind of tubular type electro-conductive glass wet electrical dust precipitator.
Background technology:
At present, the overall deteriorating trend of China's environmental aspect is contained not yet at all, and environment contradiction highlights day by day, and environmental protection pressure continues to strengthen.Subregion and urban atmosphere haze phenomenon are given prominence to, and many regional discharge of major pollutant amounts exceed environmental carrying capacity.And the flue dust of all types of industries discharge is air-polluting main source.Therefore, country is to flue dust and SO 2discharge proposes stricter requirement.State Council explicitly pointed out in the reply suggestion of " key area prevention and control of air pollution " 12 " planning ": by 2015, and key area industry smoke-dust discharge capacity declines 10%; Pellet (PM 10), fine particle (PM 2.5) average annual concentration declines 10%, 5% respectively.Wherein, 13 key areas such as Jing-jin-ji region, the Yangtze River Delta, Pearl River Delta are by PM 2.5fine particle includes performance assessment criteria in, and the average annual concentration of fine particle declines 6%; The compound atmosphere pollution of above-mentioned zone will be effectively controlled, and acid rain, gray haze and photochemical pollution will obviously reduce.In the prior art, traditional flue gas absorbing device, cannot meet the requirement of the fine particulates minimum discharge concentration of increasingly stringent, it is also proposed higher requirement to the Performance And Reliability of deduster.Electric cleaner is because of it has that efficiency of dust collection is high, wide accommodation, operating cost are low, reliability is high, easy to use and advantages such as non-secondary pollution are widely used in industrial circle fume treatment.Dry electric precipitation device compared by wet electrical dust precipitator, have the power controlling combined pollutant especially, to dust that is fine, viscosity or high specific resistance, and acid mist in flue gas, heavy metal (Hg etc.) collecting effect be also very desirable.Therefore, wet-esp Technology and equipment at home and abroad emerges in large numbers and application of succeeding in succession.But wet electrical dust precipitator is applied at the early-stage at home, also there is series of problems.Because smoke treatment is saturated wet flue gas, corrosivity is very strong, how to carry out equipment anticorrosion, improves life of product, reducing operating cost is one of key factor of design, and current domestic wet electrical dust precipitator flue gas flow rate is lower, floor space is comparatively large, and consumptive material is more, this does not generally affect new-built unit, for the old unit of having gone into operation, can be very limited for the place of transformation, seriously constrain the large scale application of wet electrical dust precipitator.
Summary of the invention:
The purpose of this utility model overcomes the deficiency that existing flue gas pollutant cleaning equipment exists, and provides a kind of and conduct electricity very well, demisting efficiency is high, a kind of tubular type electroconductive frp wet electrical dust precipitator of long service life, compact arrangement of equipment.
Technical solution of the present utility model is: provide a kind of tubular type electro-conductive glass wet electrical dust precipitator, a kind of tubular type electro-conductive glass wet electrical dust precipitator, comprises insulated case, air inlet, exhaust outlet, spray equipment, take-up device, weight, inspection manhole, water leg, brace summer, high-voltage DC power supply, the hot-air blowing system of interconnective housing, receiving electrode entablature, receiving electrode sill, cathode suspended framework, insulated case not with lead-in wire, band lead-in wire; It is characterized in that: also comprise anode tube bank, distribution device in gas-fluid, corona electrode; Cloth air chamber, dirt pocket and lower chamber from top to bottom successively in housing; Cloth air chamber is made up of air inlet, airflow distribution device, spray equipment; Form the dirt pocket of a non-homogeneous high-voltage electrostatic field by cathode suspended framework, receiving electrode entablature, anode tube bank, cathode line, receiving electrode sill and negative electrode take-up device composition; Lower chamber is then made up of exhaust outlet, inspection manhole and water leg, and exhaust outlet is connected with chimney with flue; Water ash mixture row mouth established by water leg; In housing, homogeneous vertical arranges that some fiberglass anodes are restrained, fiberglass anode tube intrafascicular uniform corona electrode, and spray equipment is placed in and anode tube bank top; High-voltage DC power supply is connected with corona electrode by the insulated case of band lead-in wire; The insulated case of band lead-in wire and hot-air blowing system connectivity, anode tube bank can be arranged to circle, square or honeycombed.Be further characterized in that: the air inlet end of airflow uniform distribution device is provided with the deflector of adjustable angle and the adjustable double-layer air-flow uniform board of percent opening; Corona electrode adopts titanium material or the lead-antimony alloy of improvement high-efficiency corrosion-resistant material; Anode tube bank adopts Corrosion Resistant Frp composite to make, with the corrosion-resistant vinylite of top grade for matrix, and carbon fiber, glass fibre is reinforcing material; Cathod system adopts: the fixed form of cathode suspended framework+negative electrode take-up device+weight.
The beneficial effects of the utility model are: anode tube bank adopts Corrosion Resistant Frp composite to make, and with the corrosion-resistant vinylite of top grade for matrix, carbon fiber, glass fibre is reinforcing material, and anti-caking is good, corrosion-resistant, is easy to processing.Anode tube internal diameter 250-500mm, long 3000-6000mm, can be arranged to circle, square or honeycombed, efficiently solves existing smoke purifying equipment to fine particle (SO 3acid mist, PM 2.5, aerosol, fine drop), heavy metal (Hg, As, Se, Pb, Cr), organic pollution cannot the degree of depth remove problem, smoke dust discharge concentration can at 10mg/Nm 3even 5mg/Nm 3below, realize minimum discharge, thoroughly solve smoke stack emission problem not up to standard.The utility model 1. is applied widely: can be widely applicable for industry wet flue gas deep purifying, the minimum discharges such as coal-burning power plant, steel plant, miniature boiler, waste incineration, cement building material, chemical industry.Dust granules and the aerosol of particle diameter 0.01 μm can be removed, ensure that dust reaches national newest standards or higher.2. novel corrosion resistant composite makes electric cleaner arrangement of mechanism flexible, can adapt to transformation place complicated at present, and owing to improve flue gas flow rate, structure is simple, and characteristics of compact layout, floor space is little.Secondary transformation project in the situation not changing existing dust removal installation, can be arranged on fume treatment end, can for a long time, stable operation.3. treatment quantity is very large.Can use multiple electric field or multiple devices parallel connection, smoke treatment amount reaches 5,000,000 m 3/ h is even larger.4. owing to have employed special pole formula formula, can be different according to flue gas operating mode, spacing is joined in reasonable adjusting pole, improves dedusting demisting efficiency, and outlet dust can realize 5mg/Nm 3minimum discharge, SO 3acid mist clearance 80-98%, the wet flue gas corrosivity through smoke stack emission lowers greatly, and the multiple pollutants such as heavy metal are also effectively controlled, and can greatly improve fume emission cleanliness factor, reduces chimney tail feathers.5. SR little, invest little, operating cost is low.
