Description
Technical field
The present invention relates to a kind of coal gasification buck non-phosphorus scale dispersing agents, belong to environmental technology field.
Background technique
In recent years, the coal gasification industry in China obtains significant progress, there has also been very big progress for Coal Gasification Technology, especially
It is even more received significant attention in terms of coal gasification ash water treatment technology.Coal gasification enterprise needs efficient, safe and stable hair
Exhibition, the operation and maintenance of gasification process system are the most important things.So, the grey water process in gasification process just seems especially heavy
It wants.
Currently, domestic do the main with phosphorous in the majority of coal gasification ash water process, we are also " the enterprise of active response country
Industry production, environmental protection is in advance " theory, research and develop novel without phosphorus grey water dispersant and reduced with the discharge for effectively controlling phosphorus
Pollution.
Coal gasification buck non-phosphorus scale dispersing agent is the novel water process developed for coal gasifying process ash water system
Medicament.In high temperature, high hard, high alkalinity ash water system, has the function of good dispersing and antisludging, while there are also certain to delay
Corrosion energy.It can not only effectively prevent the fouling of coal gasification ash water system equipment pipe, moreover it is possible to effectively control inorganic salt crust,
Metal oxide and gluey deposition, it is ensured that equipment operates normally.
Summary of the invention
The purpose of the present invention is to provide one kind to have good dispersing and antisludging effect, while there are also certain corrosion inhibitions
Coal gasification buck non-phosphorus scale dispersing agent.
The technical solution adopted by the present invention is as follows: a kind of coal gasification buck non-phosphorus scale dispersing agent, the dispersing agent is by polyphenyl
Olefin(e) acid or polyaerylic acid sodium, hydrolysis of polymaleic anhydride, multiple copolymer and water mix, wherein polyaerylic acid or polyaerylic acid
Sodium, hydrolysis of polymaleic anhydride, multiple copolymer and water mass ratio be 2.5~3.3:2.2~3.1:0.8~1.3:4.7~
5.4。
Further, the polyaerylic acid or polyaerylic acid sodium, hydrolysis of polymaleic anhydride, the quality of multiple copolymer and water
Than for 3:3:1:5.
Further, the multiple copolymer is acrylic acid -2- acrylamide -2- methyl-prop sulfuric acid copolymer.
Further, the preparation method of the dispersing agent is, firstly, water is added, to sequentially add polyaerylic acid or polyphenyl
Olefin(e) acid sodium, hydrolysis of polymaleic anhydride, acrylic acid -2- acrylamide -2- methyl-prop sulfuric acid copolymer finally add water, stirring
Uniform 10 minutes.
In above scheme, polyaerylic acid, polyaerylic acid sodium (P-1) be suitable for power plant, chemical plant, chemical fertilizer factory, oil plant and
Dirt dispersion agent in the recirculating cooling water systems such as air-conditioning system.
Hydrolysis of polymaleic anhydride (H-20) is usually compound with organic phosphate with 2-5ppm, is used for circulating water, oil field
Water filling, crude oil dehydration, the interior processing of the furnace of low-pressure boiler have the function of that good inhibition scale generates and removing is old dirty, scale inhibition
Rate is up to 98%.When it is compounded with 1-2mg/l zinc salt, the corrosion of steel can be effectively prevented.It is alternatively arranged as in textile department
Textile purificant can reduce the ash content of textile.When being used alone or being used in combination with other organophosphorated salts, dosage generally exists
2-5mg/l makees when corrosion inhibition use dosage in 10-20mg/l.
Acrylic acid -2- acrylamide -2- methyl-prop sulfuric acid copolymer (multiple copolymer)；It is profound to be mainly used as open type industry
Unreal cooling water system, rejection of oil flied effluent system, the dirt dispersion agent of metallurgical system circulating water treatment, the cooling of steel plant's elution
Water prevents Fe2o3 Stickydeposit, and makees the dispersing agent of Fe2o3 when pre-filming treatment, dosage 80-100mg/l, can with it is organic phosphorus
Salt, zinc salt are used in compounding, suitable for pH value 7.0-9.5 water quality.
The allocation ratio of raw water can carry out the allotment of different proportion according to different enterprise scenes water quality.
The beneficial effects of the present invention are:
The present invention is water-soluble compound medicament, nontoxic, pollution-free, stable chemical performance.High temperature resistant, high pressure, high-alkali performance
Well, not facile hydrolysis.Without phosphorus ash water dispersant is by chelating solubilising, distortion of lattice, the principles such as identical charges repel each other in ash water system
Middle to play good, adding can reach few at dirt on a small quantity, at soft dirt, the effect that deposits less.Meanwhile this present invention can prevent coal gas
Ashing water system equipment pipe fouling controls inorganic salt crust, metal oxide and gluey deposition, it is ensured that the normal operation of equipment.
Additional aspect and advantage of the invention will be set forth in part in the description, and will partially become from the following description
Obviously, or practice through the invention is recognized.
