Abstract
The invention mainly aims to provide an antiscaling agent which can effectively remove scale samples produced in a hazardous waste leachate distilling apparatus. The technical scheme for achieving the purpose is as follows: the antiscaling agent comprises the components in mass concentration as follows: 5%-9% of disodium ethylene diamine tetraacetic acid, 0.2%-0.5% of urotropine, 0.5%-3% of triethanolamine, 1%-4% of sodium hydroxide and 0.005%-0.03% of a penetrant. According to the technical scheme, after the leachate distilling apparatus is cleaned with the prepared antiscaling agent for a period of time, obvious scale samples are not seen in the distilling apparatus, and the distilling apparatus restores original disposal capability after rebooted.
Description
Technical field
The present invention relates to a kind of scale remover.
Background technology
The Hazardous wastess such as the mud after the inorganic surface treatment waste brought by industrial production, inorganic residues, Industrial Waste Water Treatments meet after landfill yard landfill requires through pre-treatment, hazardous waste landfill will be entered and carry out security landfill, because the immersion of the planar water in refuse and natural precipitation creates the percolate of Hazardous wastes immediately after hazard waste landfill.Hazardous wastes percolate forms mainly sodium salt in general, sylvite, calcium salt, organism, ammonia nitrogen, phosphoric acid salt, suspended substance and heavy metal etc., sewage drainage standard is met in order to make percolate, distillation plant must be adopted to carry out distillation to percolate dispose, but in percolate still-process, the inwall of distillation plant inwall particularly heating tube part will soon fouling, after general distillation plant runs 3-5 week, the processing power of equipment obviously declines, it has a strong impact on the normal operation of equipment, fouling place is removed as carried out not in time and device internal pressure namely can be caused suddenly to increase once steam passage is blocked by dirty sample, cause to produce and stop, even there will be industrial accident.So just need to adopt suitable scale remover to remove the dirty sample being attached to still kettle inwall, to ensure the continuous safe operation of producing.Do not have the special scale remover used for above-mentioned Hazardous wastes percolate water distilling apparatus at present, scale remover selects improper not only can generation evaporation unit corrode and substantially do not have solute effect to dirty sample.
Summary of the invention
Main purpose of the present invention is to provide a kind of scale remover, and this scale remover can effectively be removed the dirty sample produced in Hazardous wastes percolate water distilling apparatus.
In order to realize foregoing invention object, the technical solution adopted in the present invention is: a kind of scale remover, comprise following mass concentration component: disodium ethylene diamine tetraacetate 5-9%, urotropine 0.2-0.5%, trolamine 0.5-3%, sodium hydroxide 1-4%, fatty alcohol-polyoxyethylene ether 0.005-0.03%.
According to technical scheme of the present invention: the scale remover of above-mentioned configuration is cleaned for some time to percolate still kettle encrustation place, as found after 12 hours, have no obvious dirty sample in still, after start, device recovers original disposing capacity again.
Embodiment
A kind of scale remover, comprises following mass concentration component: disodium ethylene diamine tetraacetate 5-9%, urotropine 0.2-0.5%, trolamine 0.5-3%, sodium hydroxide 1-4%, fatty alcohol-polyoxyethylene ether 0.005-0.03%.The scale remover of above-mentioned configuration is squeezed in percolate still kettle heating tube by pump, and forced service 12 hours, after pump is out of service, have no obvious dirty sample in still kettle, after start, device recovers original disposing capacity again.This cleaning and descaling process is without the need to heating, and whole scale removal environment is alkaline environment, can not produce any corrosion behavior to device.
Further optimisation technique scheme, described each constituent mass concentration is: disodium ethylene diamine tetraacetate 6-8%, urotropine 0.3-0.4%, trolamine 1-2%, sodium hydroxide 2-3%, fatty alcohol-polyoxyethylene ether 0.01-0.02%.Under this condition, the descale effect of scale remover reaches optimum, and dirty sample is removed more thorough, more fast.This scale remover not only distills to percolate the effect that the dirty sample produced effectively can play removing, can certainly be used for other similar needs and remove in the production link of dirty sample.
Embodiment 1: configuration scale remover: disodium ethylene diamine tetraacetate 5%, urotropine 0.2%, trolamine 0.5%, sodium hydroxide 1%, fatty alcohol-polyoxyethylene ether 0.005%.
Embodiment 2: configuration scale remover: disodium ethylene diamine tetraacetate 9%, urotropine 0.5%, trolamine 3%, sodium hydroxide 4%, fatty alcohol-polyoxyethylene ether 0.03%.
Embodiment 3: configuration scale remover: disodium ethylene diamine tetraacetate 6%, urotropine 0.4%, trolamine 1%, sodium hydroxide 2%, fatty alcohol-polyoxyethylene ether 0.01%.
Embodiment 4: configuration scale remover: disodium ethylene diamine tetraacetate 8%, urotropine 0.4%, trolamine 2%, sodium hydroxide 3%, fatty alcohol-polyoxyethylene ether 0.02%.
Embodiment 5: configuration scale remover: disodium ethylene diamine tetraacetate 7%, urotropine 0.35%, trolamine 1.5%, sodium hydroxide 2.5%, fatty alcohol-polyoxyethylene ether 0.015%.
The scale remover configured in above-described embodiment is used for the removing of dirty sample in water distilling apparatus, finds works very well, further demonstrate the cleaning performance of this scale remover, also improve the disposing capacity of water distilling apparatus.
