Description
Technical field
The invention belongs to chemical fields, are related to canvas press cloth cleaning, specially a kind of pmida canvas press cloth cleaning
Method.
Background technology
Filter press is widely used in a kind of production equipment special that medicine, chemical industry, fine chemical product filter, and production
Crucial emphasis equipment in the process.For applicant in 5000 tons of pmida production lines of newly-built annual output, design uses GXG8C-3200
2, type filter press, every filter area are 8m2, filter cloth is using polypropylene fibre fibers material, and acid and alkali-resistance is corrosion-resistant, and filtering fineness is
300 mesh.When starting to put into operation, the rate of filtration and product quality of filter press are attained by designed productive capacity and require, and one
As filter a batch materials and can be completed at 4 hours or so, if continuously after filtering 4-5 batches, material filtering speed is just apparent to be become
Slowly, it is difficult to filter, filter a batch materials sometimes and then need also to filter for 6-7 hours and do not do, output is decreased obviously, and product is unqualified
Quantity gradually increases.At this moment producers must clean filter cloth, due in filter press there is toxic, pernicious gas and
Smell, producers must dress breathing mask, anticorrosive property acid and alkali-resistance rubber overshoes, anticorrosive property acid and alkali-resistance gloves, by manhole road
Door is opened, and producers enter in filter press carries out cleaning material to the material on filter cloth with nonmetallic scoop, and material is cleared up
Go out outside filter press, then carry out scrubbing cleaning with hairbrush and tap water, cleaning every time needs 2-4 people, 4 hours or so, could clean
It completes.Since cleaning canvas press cloth operating environment is severe, labor intensity is big, is difficult that will remain in filter cloth with this cleaning method
Material in hole is cleaned out, and the filter area of filter cloth is made to gradually decrease, and filter press filtering is difficult, cause often to clean filter cloth with
Filter cloth is frequently replaced, production yields is low, and production cannot be normally carried out with opening with stopping, and causes to be increased with coal electricity consumption and water consumption, raw
Production cost increases, and Business Economic Benefit is decreased obviously.
Invention content
The object of the present invention is to provide a kind of pmida canvas press cloth cleaning methods, can be effectively to filter using cleaning solution
Cloth is cleaned, and does not interfere with equipment and the service life of filter cloth, can be recycled, easy to operate, safe and reliable economical
It is applicable in.
In order to solve the above technical problems, the technical solution adopted in the present invention is：A kind of pmida canvas press cloth cleaning
Liquid contains following component by weight in the cleaning solution：Mass concentration is the sodium hydroxide solution 6000-8000 of 10-15%
Part, 0.8-1.2 parts of sodium alkyl benzene sulfonate, 0.8-1.2 parts of softening agent and 0.8-1.2 parts of di-n-butyl ether.
In the scheme of optimization, following component by weight is contained in the cleaning solution：The sodium hydroxide that mass concentration is 13%
1 part of 7000 parts, 1 part of sodium alkyl benzene sulfonate, 1 part of softening agent and di-n-butyl ether.
The sodium hydroxide solution adds water to be formulated using Ionic Membrane.Its alkalinity is strong, is easy to keep pmida molten
Solution, raw material is easy to get, cheap, economic and practical, and production cost is low, primary raw material of the present invention as cleaning solution.
Sodium alkyl benzene sulfonate（LAS）Oxidizable, foaming power is strong, and detergency is high, and easily with various additive compounds, cost is relatively low,
It is very outstanding anion surfactant.Since its biological degradability can be more than 90%, environmental pollution degree is small, especially
It has better effect to particulate fouling removing, is highly suitable to be applied for industrial cleaning agent.
Further, the softening agent is ester based quaternary ammonium salt.
Since the third human relations fiber filter cloth is in the stronger pmida filtering of acid-base property, it is easy that filter cloth is made to harden, is filtered in product
In, filter cloth is easy in pressure-filtering process damaged, replacement without preferable elasticity, is unfavorable for production system stabilization, and increase production
Cost, it is time-consuming, so that labor intensity of operating staff is increased, operating environment is poor, is unfavorable for the health of operating personnel, this hair
It is very crucial to extending filter cloth usage time by increasing softening agent in bright.
The dissolving power of di-n-butyl ether is strong, is especially a kind of conjunction well to organic synthesis medicine, chemical industry, pesticide synthesis reaction
At reaction dissolvent, di-n-butyl ether is added in the present invention, it can be rapidly by the material dissolution in filter cloth hole, when greatling save cleaning
Between, and clean thoroughly clean.
The method of the double sweet phosphine canvas press cloths of cleaning of the cleaning solution, the specific steps are：
1）Remaining material in filter press is cleaned out, and prepares cleaning solution；
2）Cleaning solution is added in filter press, stirring, impregnate, be stirred for by way of washed；It is then exhausted from clear
Washing lotion recycles；
3）Add water to be stirred cleaning, liquids recovery is finally discharged；
The cleaning to canvas press cloth is completed by aforesaid operations.
Further, in filter press when the cleaning of remaining material, the slurry of mobility is formed by adding water to stir, is then born
Pressure extraction, can repeatedly clean out.
Further, the mixing time is 5-10min, soaking time 10-15min.
Further, the step 3）The addition of middle water is 2 times of the addition of cleaning solution.
The present invention according to needed in the physics of pmida product, chemical property and production process use chemical raw material：Ionic membrane
Liquid caustic soda（NaOH）Content is 32%, hydrochloric acid（HCl）Content is 32%, formaldehyde（CH2O）Content is the physics of 37% grade, chemical property
Characteristic is researched and analysed, and pmida is not readily dissolved in water and is soluble in highly basic.In order to make cleaning solution raw material be easy to get, scavenging period
Soon, cleaning is thoroughly clean, and cleaning solution production cost is low, adaptable, and cleaning operation is convenient, without new environmental pollution, moreover it is possible to return
It receives and utilizes cleaning solution.
It mainly has the beneficial effect that：
1, pmida canvas press cloth is cleaned using cleaning solution, the material being blocked in filter cloth hole can be passed through cleaning solution
It is all dissolved out after immersion, so that the filter area of filter cloth has been obtained performance utilization of confiscating, so that filter cloth is cleaned up thoroughly, filter cloth
Filter area greatly improves.
2, after cleaning canvas press cloth using cleaning solution, filter press output is made to improve a lot, it is clear that cleaning solution is not used
Before filter wash cloth, often cleans 1 time and may filter that 10 batches or so, about produce 25 tons, every block of filter cloth most multipotency uses 15 days.Use cleaning
After liquid cleans filter cloth, often clean and may filter that 40 batches or so for 1 time, about produce 100 tons, and every block of filter cloth using 50 days or so or
Time is longer.
3, after cleaning canvas press cloth using cleaning solution, scavenging period greatly reduces, and original was with 3 hours or so, now only with 1
Hour or so, and producers' labor intensity is made to substantially reduce, work situation is greatly improved.
4, it after cleaning canvas press cloth using cleaning solution, is greatly improved using production line production capacity, product quality is significantly
It improves, the 200-300 tons/moon can only be produced former every month, 500 tons/month or more can be produced now, original product quality pass rate is not
To 85%, 100% or more can reach now, prevented substandard product appearance substantially.
5, pollution-free using cleaning solution cleaning canvas press cloth, cleaning solution recycles, and cleaning raw material is easy to get, producers
Easy to operate, safe and reliable, production cost is low, and production capacity is made to improve, and production cost reduces, energy saving, consumption reduction, enterprise
Economic benefit significantly improves.
