Abstract
The invention relates to a method for steel slag hot stewing through concentrated water. The method includes the following steps that sewage of a drainage system is treated through a reverse osmosis water treatment system to obtain the concentrated water; the concentrated water is pumped into a circulating pool, and then pumped into a slag stewing cover to be subjected to steel slag hot stewing; water obtained after steel slag hot stewing is drained into a water lifting well through a passage; the water in the water lifting well is pumped into the drainage system through a water pump; and mixed sewage in the drainage system is then pumped into the reverse osmosis water treatment system to be treated so as to obtain the concentrated water, and then the operation of the steps are repeated circularly. The concentrated water is used for conducting steel slag hot stewing by replacing fresh water, so that fresh water consumption in the steel slag hot stewing production process is lowered; recycling of the concentrated water is achieved, and water environment pollution is eliminated; and the pool cleaning labor intensity of workers is relieved.
Description
Technical field
The present invention relates to steel slag hot boils in a covered pot over a slow fire technology, carry out, particularly to a kind of, the method that steel slag hot is boiled in a covered pot over a slow fire using concentrated water.
Background technology
The generally stewing technique of steel slag hot fills into new water using slag stewing circulating water pool, gets to enforcement slag stewing at slag stewing lid by water pump
Operation, after slag stewing, water flows into water lift Jing Chu by gutter, flows into circulation after the cooling of circulating water pool cooling tower got to by water pump
Pond, recycles；Need daily to consume substantial amounts of new water；Slag stewing water produces a lot of sediments in pond in cyclic process,
Cleaning is difficult；Outside the concentrated water that sewage disposal is produced by reverse-osmosis treated, row pollutes the environment.
Content of the invention
The present invention is to solve above-mentioned problem, there is provided carry out, using concentrated water, the method that steel slag hot is boiled in a covered pot over a slow fire, and it solves skill
The technical scheme of art problem is:
Carry out the method that steel slag hot is boiled in a covered pot over a slow fire using concentrated water, step is as follows:
1) sewage disposal: the sewage of drainage system is processed by reverse osmosis water treatment system, obtains concentrated water, enter concentrated water
Pond；
2) concentrated water in concentrated water pond pumps into circulating water pool, then pump into slag stewing lid carry out steel slag hot boil in a covered pot over a slow fire, water temperature is upgraded to 145-155 DEG C
High-temperature water；Through the filtration washing of high-temperature steel slag, dense hardness of water and electrical conductivity all decrease；
3) high-temperature water after steel slag hot is boiled in a covered pot over a slow fire enters water lift well by vestibule ditch；
4) water of water lift well is squeezed into drainage system by water pump and is mixed into combined sewage with sewage；
5) combined sewage of drainage system pumps into reverse osmosis water treatment system again and carries out process and obtains concentrated water, enters concentrated water pond, then enters
Row 2), 3), 4) operation of step, iterative cycles.
The method have the advantages that
1) reduce steel slag hot and boil in a covered pot over a slow fire the new water consumption in production process；
2) realize the recycling of concentrated water, prevent water environment pollution；
3) reduce the labour intensity that workman clears up pond.
Brief description
Fig. 1 is that the present invention carries out the process chart of the method that steel slag hot is boiled in a covered pot over a slow fire using concentrated water.
In figure: 1. concentrated water pond, 2. circulating water pool, 3. slag stewing lid, 4. water lift well, 5. drainage system, 6. water treatment system.
Specific embodiment
Below in conjunction with the accompanying drawing of the present invention, technical scheme is clearly and completely described.
Carry out the method that steel slag hot is boiled in a covered pot over a slow fire using concentrated water, step is as follows:
1) sewage disposal: the sewage of drainage system 5 is processed by reverse osmosis water treatment system 6, obtains concentrated water, enter concentrated water
Pond 1；
2) concentrated water in concentrated water pond 1 pumps into circulating water pool 2, then pump into slag stewing lid 3 carry out steel slag hot boil in a covered pot over a slow fire, water temperature is upgraded to 145-155
DEG C high-temperature water；Through the filtration washing of high-temperature steel slag, dense hardness of water reduces by 10%, and hot slag stewing is obvious to cod removal effect,
Ammonia nitrogen removal frank is about 50% about；
3) high-temperature water after steel slag hot is boiled in a covered pot over a slow fire enters water lift well 4 by vestibule ditch；
4) water of water lift well 4 is squeezed into drainage system 5 by water pump and is mixed into combined sewage with sewage；
5) combined sewage of drainage system 5 pumps into reverse osmosis water treatment system 6 again and carries out process and obtains concentrated water, enters concentrated water pond 1, then
Carry out 2), 3), 4) operation of step, iterative cycles.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, the change or replacement that can readily occur in,
All should be included within the scope of the present invention.
