Technology for preparing sulfuric acid

Номер: CN103072957A
Автор: Bai Wei, Dai Chengwu, Cai Chengyou, Yu Yilin, Zhang Suli, Lv Cheng, Yuan Songbai, Liu Zhuo
Принадлежит:

The invention relates to a technology for preparing sulfuric acid, in particular to a technology for preparing sulfuric acid by taking low-quality sulfur and a waste salt liquid containing sulfur that are generated by a coke oven gas wet oxidation desulfurization technology which takes ammonia as an alkali source and takes quinone, cobalt and ferrum compositions such as HPF as catalysts as raw materials, and through processes of incineration, waste heat recovery, wet purification, wet contact method conversion, and condensation into acid. The technology thoroughly solves the problem of treatment of a waste desulfurization liquid and low-quality sulfur that are generated by the coke oven gas wet oxidation desulfurization technology which takes the quinone, cobalt and ferrum compositions such as HPF, PDS and ZL as the catalysts, so that the desulfurization technology is completed; produced sulfuric acid can serve as a raw material for deamination of coal gas of a factory, and for production ...

Insulating tree shears

Номер: CN103202184A
Автор: Dai Chengwu, San Haifeng, Lei Zhaojiang
Принадлежит:

Insulating tree shears comprise an insulating rod. A lower shear is arranged at the top end of the insulating rod. An upper shear and a pressure handle are hinged to the lower shear. A torsion spring is arranged between the pressure handle and the lower shear. The pressure handle is meshed with the upper shear through gear teeth. A moving pulley block is disposed at the tail end of the pressure handle. A fixed pulley block is arranged on the insulating rod. A pull cord is disposed on the insulating rod and passes through the moving pulley block and the fixed pulley block. The lower shear is provided with teeth, and a cutting edge is arranged on one side of the teeth. The insulating rod effectively prevents electric shock. The moving pulley block increases pulling force, the pressure handle is connected with the upper shear by meshing of gear teeth high in transmission efficiency, the shearing force is large, and accordingly the insulating tree shears are easy to operate, convenient for ...

Принадлежит:

The invention belongs to the field of afterheat recovering of coke oven gas, and in particular relates to a coke oven gas afterheat recovering method and a coke oven gas afterheat recovering device. Coke oven gas recovery and tar recovery are integrated, high-temperature heat energy and low-temperature heat energy in the gas are respectively recovered by using a segmental recovery mode; and the gas is cooled by using a mode of spraying tar during recovering. The device comprises a high-temperature afterheat boiler, an oil-gas separator, a gas cooler, an oil-water separator and a low-temperature afterheat boiler, wherein a gas inlet of the high-temperature afterheat boiler is connected with a gas outlet of a coke oven carbonization chamber raw coke oven gas; and a gas outlet of the oil-gas separator is connected with the gas cooler. Compared with the prior art, the method and the device have the advantages that high-temperature heat energy can be recovered and low-temperature heat energy ...

Portable stand tripod

Номер: CN103204444A
Автор: Dai Chengwu, San Haifeng
Принадлежит:

A portable stand tripod comprises three support legs. The portable stand tripod is characterized in that the support legs include one basic support leg and two stretching support legs, a crossbeam is arranged at the top end of the basic support leg, an included angle formed between the crossbeam and the basic support leg is 90 degrees, sleeves are respectively arranged at the top ends of the stretching support legs, an included angle between each sleeve and each stretching support leg is 15-45 degrees, and a hooking ring is arranged in the middle of the crossbeam. The portable stand tripod is simple in structure, low in precision requirements, small in manufacturing difficulty and low in manufacturing cost. The basic support leg is connected with the stretching support legs via the sleeves and the crossbeam, so that disassembling is realized, and transportation and mounting are facilitated.
