Integrated device for recycling heat exchange oil and purifying oil fume and implementation method

Abstract

The invention relates to an integrated device for recycling heat exchange oil and purifying oil fume and an implementation method. The device is provided with an oil mist recovery and adsorption device, a waste gas purification device, a heat exchange oil storage tank, a suction fan and an exhaust chimney. The oil mist recovery and adsorption device is composed of a bottom oil accumulation tank, amiddle cooling tank, an upper adsorption tank and a mist catcher, and is provided with a cooling coil, a polymer adsorption plate, an adsorption felt and a stainless steel wire coil. The mist catcheris mounted at the top of the upper adsorption box, so that residual mist can be thoroughly separated into waste gas. The oil mist recovery adsorption device is connected with the waste gas purification device through a connecting pipeline. And the waste gas purification device is provided with a guide plate, honeycomb activated carbon and a perforated baffle. Under the suction action of the suction fan, the waste gas enters the honeycomb activated carbon through the flow guide plate to be adsorbed and purified; and then the waste gas is discharged from the discharge chimney through the connecting pipe, so that the effects of thoroughly removing oil mist and converting the oil mist into heat exchange oil with reuse value are achieved, and the oil fume treated by the purification system canbe discharged after reaching the standard.

Description

technical field [0001] The invention relates to a purification system for recovering and recycling heat exchange oil of bearings of blast furnace blower motors in ironmaking and purifying oil fume, and in particular to an integrated device and implementation method for recycling heat exchange oil and purifying oil fume.

AI Technical Summary

Problems solved by technology

[0003] When the ironmaking blast furnace is refining molten iron, it needs a large amount of oxygen to give auxiliary combustion to increase the calorific value of combustion. The oxygen is transported to the blast furnace cavity with blast furnace blast equipment. Due to the high power of the blast furnace blower, its motor bearing is prone to heat. The continuous operation of the bearing can cause the bearing bush to expand due to heat and cause a stuck fault, thus affecting the normal ironmaking operation

Therefore, it is necessary to perform heat exchange and cooling on the bearings of the blast furnace blower. The usual means of heat exchange and cooling is to use medium-load gear oil to circulate back and forth. The circulating medium-load gear oil produces oily fumes due to heat generation. The compound mixture of particles can cause chemical pneumonia if inhaled into the lungs by the human body. Long-term or repeated exposure can cause dermatitis, which seriously endangers the physical and mental health of employees.
