Abstract
The present invention provides a scavenger for coal tar in a workshop cooler for quickly scavenging ammonium hydrogen carbonate. The present invention is formed by the polymerization of trichloromethane, ethanol, xylol, benzene, n-butyl acetate, ethyl acetate, normal butyl alcohol and acetone. A production method has the steps that the raw materials are respectively screened, are proportionally added in a container one by one and are fully and evenly mixed to become a finished product. A cooler to be scavenged is put in the mixed solution and is soaked for one to two hours, and then the coal tar can be dissolved by solvent which is then poured from the cooler. The coal tar in the cooler is scavenged cleanly. The present invention has the advantages of time saving, labor saving, good effect and low cost.
Description
The present invention relates to a kind of clean-out system, the particularly a kind of scavenging agent that can dispose coal tar in the water cooler of bicarbonate of ammonia workshop fast.
In the water cooler that use in the synthetic workshop of existing bicarbonate of ammonia chemical fertilizers production, will have a large amount of coal tar to adhere to about every half a year on its container inner wall and the inside pipe wall, stopping up gas can not be unimpeded, influence is produced, and all is to work by hand in the time of removing it, wastes time and energy, poor effect, the cost height.
The purpose of this invention is to provide a kind of scavenging agent that can dispose coal tar in the water cooler of bicarbonate of ammonia workshop fast.
Task of the present invention is finished as follows, it is made up of following 8 kinds of organic solvents, various component contents with weight ratio in respect of trichloromethane 10-26.7 part, ethanol 7.3-8.7 part, dimethylbenzene 13.3-24.6 part, benzene 13.3-20 part, acetic acid butyl ester 6.7-10.7 part, ethyl acetate 5.3-9.3 part, propyl carbinol 6.7-10 part, acetone 4-8 part, its production method is through screening respectively with above-mentioned raw materials, add one by one in the container, thorough mixing evenly promptly is a finished product again.
The present invention has following embodiment:
| Acetic acid butyl ester ethyl acetate propyl carbinol acetone | 10 8.7 8 5.3 | 6.7 5.3 6.7 4 | 10.7 9.3 10 8 |
Because of the composition more complicated of coal tar, so adopt above multiple organic solvent that it is dissolved removing.During use, water cooler to be removed is put into this mixing solutions, soak 1-2 after individual hour, coal tar can be poured out solvent by this dissolution with solvents in water cooler, and the coal tar in the water cooler can be eliminated totally.Time saving and energy saving, effective, cost is low.
