Slag cleaning of sulfur tank?
Thread Content
Our sulfur tank, settling tank, and refined sulfur tank are flat-bottomed structures lined with carbon steel and ceramic tiles. After several years of operation, the refined sulfur tank is in good condition, but a lot of impurities and dirt have accumulated at the bottom of the sulfur tank, which affects the heating area of the heating coil of the sulfur tank. We are also worried about excessive impurities, so we move them backward to the settling tank and refined sulfur tank. In the end, if the oil gun of the sulfur incineration furnace gets blocked, the sulfur gun will be blocked, causing frequent shutdowns. The problem is how to clear out the dirt and impurities at the bottom of the sulfur tank. Sulfur is easy to solidify, which is really troublesome. Please help me see if there is a more convenient and effective solution. Thanks!
We directly discharge the liquid sulfur from the slag discharge port at the bottom while the liquid sulfur is insulated. A ridge should be built around the slag discharge port in advance, and the ground inside the ridge should be moistened with water.
The tiles lining the molten sulfur tank are inappropriate in my personal opinion, and the original poster’s problem is the problem. How to clear the tank? It becomes even more troublesome after solidification. Using a hammer and steel drill will inevitably damage the tiles. Hot cleaning is difficult and can easily injure people. Try using a large amount of high-pressure water to loosen the dregs, which may be easier to clean.
There is no other good way but to drain it when it is in a liquid state. If it is not drained cleanly, put it in and clean it up bit by bit. This post was last edited by limingshuguang on 2009-2-7 15:11 ]
1. Reduce the liquid sulfur level in the tank to the minimum (use a pump or connecting pipe) 2. Lift out the heating coil while it is hot (if it can still be lifted) 3. Open the manhole and drain the residual liquid sulfur to the ground (enclose a cofferdam in advance) 4. After cooling down and waiting for the residue in the tank to solidify, manually enter and clean it with an air pick. Be careful not to damage the coil!
We have dug sulfur tanks many times, and there are a few things to pay attention to.: 1. Reduce the liquid level to the minimum before digging the trench. ； 2. After turning off the steam, lift the coil out before the sulfur solidifies, otherwise it will be very troublesome after solidification. ； 3. Pour water into it when cooling
It will be more troublesome if the sulfur tank is underground or semi-underground, and some sulfur tanks are not even designed with a drain valve.
Haha, we have cleaned it many times. The pool is underground. Damn it. The coils must be lifted out when the sulfur is in liquid form. At least one group should be lifted every other group. Otherwise, there will be no construction space. It is best to fish out as much as possible when the sulfur is in liquid state.
I have already made a structure where our trough concrete pouring is lined with ceramic tiles and there is no drainage outlet. Since several stirrers were not working properly, slag accumulation was serious in the molten sulfur tank and coarse sulfur tank. Treatment method: 1. You can take out the heating tube first. If the slag accumulation is severe, it cannot be taken out. 2. Lower the liquid level as low as possible. Measure the distance between the pump inlet and the bottom, and then add a short pipe to the pump inlet to empty the sulfur at one time. 3. Cut off the steam and cool down. 4. When fire steam and emergency water are guaranteed, several people can be opened. 5. Use a pneumatic pick for manual cleaning, and pay attention to the protection against sulfur fire on site. (If the heating tube cannot be taken out, it can only be taken out one by one while cleaning the slag, but after taking it out, pressure test and leak elimination must be carried out)
Hello, we have an owner who insists on building this kind of underground sulfur tank in order to control investment. Can you take some photos, flow charts and drawings of the sulfur tank for us to learn from?* For a moment? 82993871@qq.com , there are rewards. Also where are you? Want to visit.
