Abstract
A kind of method cleaning desulfurization filler that the present invention provides, can solve filler and be blocked the problem affecting packing specific area and desulfuration efficiency by impurity such as sulfur.The method is: will be taken out from desulfurizing tower by the filler of the impurity blockings such as sulfur, first it is rinsed with water under high pressure, wash away the most of sulfur being attached to filling surface, drain the moisture on filler, again filler is put in the old corrosion-resistant rinse bath having concentrated sulphuric acid and dissolve, and indirectly heat with thermal mediums such as steam, remove the remaining sulfur in filler gap, filler is taken out after dissolving by impurity to be attached, after filling surface sulphuric acid drains, again filler is put in clear water reserviors and be carried out, take out in can loading desulfurizing tower after drying and be continuing with.The method have the advantages that and utilize price relatively low and the concentrated sulphuric acid of easy buying thoroughly cleans the foreign material such as the sulfur being attached to filling surface, the filler after cleaning is identical with new filler effect, it is achieved the Reusability of filler.
Description
Technical field
The invention belongs to coke oven gas desulfurization tower packing clean and reuse field, particularly relate to one and utilize concentrated sulphuric acid
Characteristic thoroughly removes the method being attached to the impurity such as sulfur within filler.
Background technology
Coke-oven plant's coke-stove gas HPF sulfur removal technology is filled with mass filler to improve hydrogen sulfide and desulfurization in coal gas in desulfurizing tower
Liquid contact area, in use due to adhesion and the deposition of the impurity such as suspension sulfur, can cause desulfurizing tower filler to block, seriously
Time packing specific area can be caused to strongly reduce, the most directly reduce desulfuration efficiency, and desulfurizing tower resistance can be made to raise, impact
The normal conveying of coal gas.When the blocking of desulfurizing tower filling body is serious, typically takes the mode of integral replacing to process, but filler price is relatively
Height, can raise by desulphurization cost.
Summary of the invention
The technical problem to be solved is to provide a kind of without integral replacing for shortcoming of the prior art
Desulfurizing tower filling body and only need to clean the cleaning method of desulfurizing tower filler.
Adopt the following technical scheme that for solving the technical problem of the present invention
A kind of method cleaning desulfurization filler, cleans (3) step, tool including high pressure water washing (1), strong sulfuric acid response (2) and water
Body method is as follows:
High pressure water washing (1): by being taken out from desulfurizing tower by the filler of the impurity blockings such as sulfur, be first rinsed 5-with water under high pressure
10min, washes away the sulfur being attached to filling surface；
Strong sulfuric acid response (2): drain the moisture on filler, then filler is put into one by one equipped with in the corrosion-resistant rinse bath of concentrated sulphuric acid
Reaction, and indirectly it is heated to 40-80 DEG C with steam, remove the remaining sulfur in filler gap, successive reaction in reaction vessel
2-4h, takes out filler after reaction；
Water cleans (3): after filling surface sulphuric acid drains, then is put in clear water reserviors by filler and be carried out, and taking out can after drying
To be continuing with in loading desulfurizing tower.
The current used in described high pressure water washing (1) are low-pressure jet, and the pressure of current is 40-80bar.
The mass fraction of described concentrated sulphuric acid is 70-85%.
In described water cleaning (3), in water, soak time is 10-20min.
Described whole during operating personnel a complete set of acid-proof clothes and face shield, and carry out in well-ventilated's environment.
The present invention develops a kind of method cleaning desulfurizing tower filler, by by the filler of the impurity such as sulfur blocking from desulfurizing tower
Middle taking-up, is first rinsed with water under high pressure, washes away the most of sulfur being attached to filling surface, drains the moisture on filler, then
Filler is put into reaction one by one in the corrosion-resistant rinse bath claiming there is concentrated sulphuric acid dissolve, and indirectly heat with thermal mediums such as steam, remove
Remove the remaining sulfur in filler gap, after reaction, filler is taken out, after filling surface sulphuric acid drains, then filler is put into clear water
Pond is carried out, takes out in can loading desulfurizing tower after drying and be continuing with, whole process operator must a complete set of anti-
Acid clothes and acid-proof face shield, and carry out in well-ventilated's environment.Can carry out clear in batches according to the concrete stopping state of filler
Wash, return rapidly dress, reduce cost, and the celadon filler after over cleaning is identical with the filler effect of new production.This
Bright advantage is to utilize price relatively low and the concentrated sulphuric acid of easy buying thoroughly cleans the foreign material such as sulfur being attached to filling surface, cleans
After filler identical with new filler effect, it is achieved the Reusability of filler.
Accompanying drawing explanation
Fig. 1 is present invention process flow chart.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail:
Embodiment 1
A kind of method cleaning desulfurization filler, cleans (3) step, tool including high pressure water washing (1), strong sulfuric acid response (2) and water
Body method is as follows:
High pressure water washing (1): by being taken out from desulfurizing tower by the filler of the impurity blockings such as sulfur, be first rinsed with water under high pressure
10min, the current used in high pressure water washing (1) are low-pressure jet, and too low hydraulic pressure effectively can not will block impurity from filling out
Material surface washing is got off, and too high hydraulic pressure then can damage celadon filler, can destroy the integrity of filler, and the pressure of current is generally
40-80bar, washes away the sulfur being attached to filling surface.
Strong sulfuric acid response (2): drain the moisture on filler, then to be put into one by one by filler equipped with mass fraction be 70% dense sulfur
Reacting in the corrosion-resistant rinse bath of acid, and be indirectly heated to 80 DEG C with steam, steam heats indirectly can make concentrated sulphuric acid and sulfur
Reaction keep higher reaction rate, avoid direct steam heating to cause the fall of concentrated sulphuric acid concentration because steam condensation simultaneously
Low so that the general reaction time is shorter.Successive reaction 2h in reaction vessel, removes the remaining sulfur in filler gap, reaction
After by filler take out；
Water cleans (3): after filling surface sulphuric acid drains, then is put into by filler and carry out soaking and washing in clear water reserviors, soaks in water
Time is 20min, takes out in can loading desulfurizing tower after drying and is continuing with.
During whole, operating personnel a complete set of acid-proof clothes and face shield, and carries out in well-ventilated's environment.
