Abstract
The invention discloses a cleaning device for valve scaling, comprising a chemical cleaning solution storage tank (1), a delivery pump (2) and a main pipeline (3); a branch pipeline (4) is connected on the main pipeline (3) for delivering the chemical cleaning solution; a control valve (5) is connected on the branch pipeline (4); various valves (7) with different nominal diameters are connected in series by connecting short pipes (6) with variable diameter on the branch pipeline (4); and then the cleaning solution returns to the chemical cleaning solution storage tank (1). Compared with the prior art, the device has the advantages of simple process, thorough cleaning of the valve scaling, and greatly improving the service life of the valve, thus saving spare parts and spare pieces, reducing production cost and the like.
Description
Technical field:
The invention belongs to the valve cleaning technique field of mechanical engineering, particularly a kind of chemically-cleaning device of valve scaling.
Background technology:
In the production of various industries, every day is online is using the valve of all kinds and size.Because the existence of various impurity components causes being easy to generate on equipment, pipeline and the valve a large amount of foulings in the solution.These foulings cause the valve can't switch, only remove the valve that more renews, and reuse and the valve that removes in time carried out returning in the production after the Chemical cleaning.
In the process of producing with alkaline process in the aluminium oxide, the valve of all kinds of online use every day and size is thousands of, and these valves are the most cheap also needs one of dozens of yuan, one in expensive valve units then up to ten thousand.Because the existence of material self property and various impurity components, in the process of convey materials, valve will produce fouling in use for some time, carries out Chemical cleaning thereby need remove.Heat and carry out soda boiling and in alumina producing, normally the valve integral body that removes is put into alkali lye.Like this, make places all on the valve all can be subjected to the corrosion of alkali lye, easily valve is washed working pressure grade bad or the reduction valve, thereby caused the consumption of valve big, improved production cost greatly.
Summary of the invention:
The technical problem that will solve of the present invention is:
A kind of cleaning device of valve scaling is provided, is washed bad easily or the reduction of working pressure grade with valve in the solution prior art, the technical problem that production cost is increased.
The present invention takes following technical scheme:
When the chemical cleaning solution in the chemical cleaning solution storage tank 1 is sent to cleaning main equipment and groove jar with delivery pump 2 by trunk line 3, on trunk line 3, connect lateral 4, on lateral 4, connect by-pass valve control 5, and on this lateral, couple together by the valve 7 of reducing connection short tube 6 with various different nominal diameters, turn back to chemical cleaning solution storage tank 1 then, form enclosed closed cycle.
When chemical cleaning solution is sent to cleaning main equipment and groove jar with delivery pump 2 by trunk line 3, open by-pass valve control 5, chemical cleaning solution enters in the lateral 4.Because certain pressure is arranged, chemical cleaning solution just can carry out Chemical cleaning and physics cleaning (the mobile flush clean of cleaning fluid in pipeline and valve) to valve scaling, after having cleaned, closing control valve 5 removes the valve that is connected on the reducing connection short tube 6 just and can be reused in the production.
The diameter that described reducing connects short tube 6 can be 100～300mm.Described chemical cleaning solution can adopt alkali lye, can adopt mother liquid evaporation to add liquid caustic soda or outsourcing caustic soda in alumina producing, and making its concentration is 300～350g/l.Also can adopt the outsourcing caustic soda is added in the entry, making its concentration is 300～350g/l.After this chemical cleaning solution caustic sodium concentration is reduced to a certain degree, can turn back to burden process continuation use in the alumina producing flow process, environment there is not any pollution.
Also can in other industry, adopt acid solution to come wash-out valve according to producing needs.
When chemical cleaning solution cleaned valve, temperature was controlled to be 60～70 ℃.Because temperature is too high, alkali liquid corrosion is strong excessively, causes the damage of valve easily.And temperature is low excessively, can reduce cleaning performance.
The present invention compared with prior art has following advantage:
The present invention compared with prior art has following advantage:
1, adopt the existing technology of cleaning main equipment and groove jar in the production that valve is cleaned, technology is simple, valve scaling is cleaned thoroughly, and it is low to clean cost.
2, in the cleaning process, chemical cleaning solution only to the valve internal flush clean that flows, does not corrode injury effect to other position of valve, makes the not reduction of working pressure grade of cleaning late gate, raising by a relatively large margin the service life of valve.Therefore, the consumption of valve significantly reduces, thereby has saved standby redundancy, has reduced production cost.
Description of drawings:
Accompanying drawing 1 is a schematic diagram of the present invention.
The specific embodiment
Embodiments of the invention:
The caustic alkali that utilizes alumina producing to buy is mixed with the caustic solution of concentration for 320g/l, is used for cleaning main equipment and groove jar as chemical cleaning solution.Control Chemical cleaning liquid temp is 65 ℃.Lateral 4 is installed on the trunk line 3 of its conveyingization clear liquid, and to connect short tube 6 by reducing on this lateral be that the valve 7 of 100mm, 150mm, 200mm, 250mm couples together with diameter, lateral 4 turns back to chemical cleaning solution storage tank 1 then, forms enclosed closed cycle.
On lateral 4, connect by-pass valve control 5.When chemical cleaning solution is sent to cleaning main equipment and groove jar with delivery pump 2 by trunk line 3, open by-pass valve control 5, chemical cleaning solution enters in the lateral 4.Because certain pressure is arranged, chemical cleaning solution just can carry out Chemical cleaning and physics cleaning (the mobile flush clean of cleaning fluid in pipeline and valve) to valve scaling, after having cleaned, closing control valve 5 removes the valve that is connected on the reducing connection short tube 6 just and can be reused in the production.
After this chemical cleaning solution caustic sodium concentration is reduced to below the 300g/l, can turn back in the alumina producing flow process burden process and prepare burden, environment there is not any pollution.
