Description
Technical field
The present invention relates to the smelting furnace technical field, be specifically related to a kind of environment-friendly type smelting furnace exhaust gas processing device.
Background technology
The development that aluminium processing and production industry have experienced decades, under a large amount of introductions and the effort of self development, domestic formation from primary aluminum produces the complete industrial chain that aluminum products are sold, and each link in the middle of producing has also nearly all lived through the innovation of technical matters.But also bound its negative effect that industrial expansion brings, even to this day, when energy growing tension, environmental pollution seriously no longer only are the topics of popular words and when existing as a powerful control criterion of enterprise, the lumber recovery of aluminium melting furnace and energy consumption management and control will seem particularly important.Employed equipment has also experienced a lot of years in the aluminium melting variation development, each development of technology is for development and national economy, improving and guiding and all played great facilitation for the protection of environment for domestic appurtenance development basically.
Existing smelting furnace, its smoke collection pipe directly connects dust storage chamber by air-introduced machine, dust storage chamber connects chimney, directly discharged to sky, both wasted heat expended fuel such as coke again to the flue gas of high heat with chimney, produce a large amount of pernicious gases such as sulfide, and produce a large amount of carbon dioxide, make the earth surface increase in temperature, produce greenhouse effects.In a word, there is the problem of a large amount of harmful environments for human survival in existing this smelting furnace, and the smelting cost height.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of scrap build simple, good in economic efficiency environment-friendly type smelting furnace exhaust gas processing device.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of environment-friendly type smelting furnace exhaust gas processing device, be connected on the smelting furnace smokejack, described exhaust gas processing device comprises a smoke filter, this smoke filter carries out filtration treatment to the harmful substance in the tail gas, be connected with the dust setting chamber in described smoke filter bottom, behind tail gas filtering, remaining gas is carried out sedimentation and handle, guarantee not have pernicious gas to discharge, at the indoor automatic dust remover that is provided with of dust settling.
Described smoke filter comprises a filter chamber, by dividing plate the filter chamber is separated into heavy metal adsorption chamber, pernicious gas adsorption chamber and dust adsorption chamber successively in the described filter chamber, communicates by through hole between each adsorption chamber;
Described heavy metal adsorption chamber mainly adsorbs the dust such as aluminium compound that contain in the flue gas, and the suction type of employing is to adsorb by place the aluminium compound adsorbent in the heavy metal adsorption chamber;
Described pernicious gas adsorption chamber mainly is that hydrogen chloride, sulfur dioxide and the oxynitrides that contains in the flue gas carried out adsorption treatment, and the suction type of employing is to adsorb by the terylene combined filtration Nomex of placing anti acid alkali performance in the pernicious gas adsorption chamber;
For further improving the physicochemical property of described terylene combined filtration Nomex, Nomex needs oven dry processing again behind the chemical solvent dipping, Nomex is 1～5m/min by the speed of chemical solvent maceration extract, and bake out temperature and time are 90 ℃～100 ℃, 20～70min.
Described chemical solvent is made up of organic siliconresin, floride-free water repellent, nonionic surface active agent, PTFE emulsion and water, and its mass percent is:
Organic siliconresin 1.0～1.5%
Floride-free water repellent 5～8%
Nonionic surface active agent 0.5～1.5%
Nano-graphite emulsion 8～13%
All the other are water.
Described dust adsorption chamber mainly is that dust in flue gas is carried out adsorption treatment, and the suction type of employing is to place the active carbon adsorption material or the composite spunlaced felt of basalt fibre adsorbs in the dust adsorption chamber.
The invention has the beneficial effects as follows: the transformation of the suitable various smelting furnaces of the present invention, implement simply to have reduced environmental pollution, reduced greenhouse, no longer include the discharge of any pernicious gas, meet the policy of government's energy-conserving and environment-protective.
