The utility model discloses a multistage wet process gas cleaning device of single tower has a tower multi-purpose, energy-conserving water conservation, the extensive characteristics of flue gas adaptation.
Description
Technical field
A kind of mono-tower multi-stage wet type flue gas desulphurization device relates to the fine solid particle that contains before the discharging of a kind of smoke treatment and the device of harmful element.
Background technology
In the various flue gases that in copper, nickel, lead, zinc smelter, discharge, all contain a certain amount of particle and pernicious gas or other element.Each manufacturing enterprise adopts electric cleaner, cyclone dust collectors, bagroom, hydrofilter and exhaust gas processing device etc., enters in the atmosphere after flue gas is handled again.
In the lead-zinc smelting industry, contain the sulfur dioxide and the plumbous zinc volatile matter of trace in the discrete flue gas, the method that generally adopts dry method to gather dust and combine with wet dust collector can capture plumbous zinc volatile matter get off simultaneously the sulfur dioxide in the tail gas is also captured.If also contain other harmful element in the flue gas, need to increase facility and capture.
Summary of the invention
The purpose of the utility model is exactly the deficiency that exists to above-mentioned prior art, provides a kind of flue gas cool-down, dedusting and harmful element of can effectively reaching to remove purpose, energy-saving and water-saving, eco-friendly mono-tower multi-stage wet type flue gas desulphurization device.
The purpose of the utility model realizes through following technical scheme.
A kind of mono-tower multi-stage wet type flue gas desulphurization device; It is characterized in that it is made up of the more piece tubular tower sections; Its structure comprises:
Flue gas air inlet tower section-this tower section is positioned at lowest part, and sidewall is provided with the smoke inlet pipe road;
Spraying absorption tower section-this tower section bottom and flue gas air inlet tower section upper end are fixedly connected, and sidewall is provided with the atomizing spray liquid shower nozzle that is uniformly distributed with;
Purify back flue gas tower section-this tower section of giving vent to anger and be positioned at top, the bottom is affixed with spraying absorption tower section upper top, on sidewall, is provided with blast pipe.
A kind of mono-tower multi-stage wet type flue gas desulphurization device of the utility model; It is characterized in that described spraying absorption tower section is the multistage series connection, establish one to three grade of shower nozzle for every section, the quantity of every grade of shower nozzle is 2 or a plurality of.
A kind of mono-tower multi-stage wet type flue gas desulphurization device of the utility model is characterized in that the said back flue gas that purifies gives vent to anger and the wire netting mist eliminator is housed on the blast pipe of tower section.
A kind of mono-tower multi-stage wet type flue gas desulphurization device of the utility model, the quantity of shower nozzle require to confirm that for reaching atomizing effect preferably, shower nozzle adopts compressed air atomizing scavenging solution according to sprinkle density; Spraying absorption tower section adopts one or more snippets series connection to increase spray progression; The kind and the content of the temperature that reduces according to the flue gas needs, dust concentration, harmful element; The shower nozzle of preparing different progression sprays corresponding decontaminating liquid, reaches the purpose that flue gas cool-down, dedusting and harmful element remove.A kind of mono-tower multi-stage wet type flue gas desulphurization device of the utility model has that a tower is used more, an energy-saving and water-saving, the scalable characteristics of flue gas.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
A kind of mono-tower multi-stage wet type flue gas desulphurization device; It is made up of the more piece tubular tower sections; Its structure comprises: flue gas air inlet tower section 2-this tower section is positioned at lowest part, and sidewall is provided with smoke inlet pipe road 1; Spraying section 4-this tower section bottom, absorption tower and flue gas air inlet tower section upper end are fixedly connected, and sidewall is provided with the atomizing spray liquid shower nozzle 3 that is uniformly distributed with; Purify back flue gas tower section 5-this tower section of giving vent to anger and be positioned at top, the bottom is affixed with spraying absorption tower section upper top, on sidewall, is provided with blast pipe 6.Described spraying absorption tower section is the multistage series connection, establishes one to three grade of shower nozzle for every section, and the quantity of every grade of shower nozzle is 2 or a plurality of; Purifying the back flue gas gives vent to anger and the wire netting mist eliminator is housed on the blast pipe of tower section.
Embodiment
The processing of plumbous smeltery's flash stove and slag cleaning furnace melt floss hole flue gas and slag cleaning furnace flue gas during smelting.
The flue gas that is lower than 300 ℃ gets into from the gas approach of flue gas air inlet tower section; Spraying section through one or more series connection successively; In each spraying section; The vaporific decontaminating liquid counter current contacting of flue gas and shower nozzle ejection, temperature are reduced to about 50 ℃ from 300 ℃, and plumbous zinc particulate and other dust granules are captured down and drain with current in the flue gas.
In scavenging solution, add alkali lye, pH value is adjusted to 7-10 between (more excellent scope is between 7.5-8.5), desulfurized effect is very desirable, simultaneously, alkaline circulation fluid helps the anticorrosion of equipment.Not it should be noted that to add lime, otherwise can cause ill effects such as pipeline scale, shower nozzle obstruction because consider the cost problem.The special harmful components that contain in the flue gas are prepared corresponding solution, in corresponding shower nozzle, spray, and reach the purpose of purification.From the water saving and the dual consideration of environmental protection, build the scavenging solution circulatory pool in use outward, when dissolved matter reaches finite concentration in the scavenging solution, scavenging solution extracted out send the next procedure processing.
