At present, in the graphitization process of the carbon industry, because of a special production process, mixed gases such as carbon monoxide, sulfur dioxide, water vapor and the like are often generated by resistance materials and heat preservation materials in a graphitization furnace under a high-temperature condition in the production and power transmission processes, and because the graphitization furnace is open equipment, the waste gas is inorganically discharged, the concentration of the waste gas at the operation site around a high-temperature furnace chamber exceeds the standard, the normal production loading and unloading operation is influenced, and certain harm is caused to the physical and mental health of staff.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a graphitization stove waste gas collection device can effectively solve present graphitization stove waste gas unorganized emission, leads to operation scene waste gas concentration on every side of the high temperature furnace chamber to exceed standard, influences normal production equipment and goes out the stove operation, can cause the problem of harm to staff's physical and mental health.
In order to achieve the above object, the technical solution of the present invention is specifically as follows:
the utility model provides a graphitization furnace waste gas collection device, includes arc flue gas cover, arc flue gas cover sets up on power transmission furnace room upper portion, the outlet flue of arc flue gas cover is connected with the cooperation of exhaust-gas cooling treatment facility through the ventilation small transfer line, exhaust-gas cooling treatment facility's gas outlet and chimney are connected.
The waste gas cooling treatment equipment comprises a ventilation main pipeline, a drain valve and a high-temperature resistant centrifugal fan, wherein a flame arrester is arranged on a smoke inlet of the ventilation main pipeline, the flame arrester is connected with a ventilation branch pipeline in a matching mode, the tail end of the ventilation main pipeline is connected with the high-temperature resistant centrifugal fan through the drain valve, and a gas outlet of the high-temperature resistant centrifugal fan is connected with a chimney.
And a flap valve is arranged on one side of the ventilation main pipeline, which is provided with the drain valve.
The shell of the flame arrester is a cast steel shell, and the filter element of the flame arrester adopts a metal mesh filter element or a corrugated filter element.
The metal mesh type filter element is formed by overlapping a plurality of layers of stainless steel or copper meshes with the diameter of 0.23-0.315 mm.
The utility model has the advantages that: the utility model discloses a waste gas that the arc flue gas cover that sets up on power transmission furnace room upper portion produced the power transmission furnace room is unified and is collected to carry into exhaust gas cooling treatment facility with waste gas through the ventilation lateral duct, utilize exhaust gas cooling treatment facility to after exhaust gas cooling handles, pass through the chimney with harmless gas and arrange to the atmosphere, reach and reduce operation scene waste gas concentration around the high temperature furnace room, the purpose of protection staff physical and mental health. Wherein, waste gas cooling treatment facility includes the main pipeline that ventilates, the drain valve, high temperature resistant centrifugal fan, the main pipeline that ventilates is through installing the spark arrester on its smoke inlet, flame separation in the mixed flue gas that carries the ventilation branch pipeline is outside, prevent that flame from getting into the main pipeline that ventilates and influencing equipment normal operating, the drain valve is used for steam and partial carbon monoxide in the discharge tube, the comdenstion water that forms behind the sulfur dioxide gas effect, at this in-process, partial carbon monoxide in the mixed flue gas, sulfur dioxide gas mixes the process that forms the comdenstion water with steam, be exactly carbon monoxide in the flue gas, sulfur dioxide gas is the process of elimination by the processing, that is to say, at this in-process, carbon monoxide, sulfur dioxide gas is eliminated. In order to prevent the flue gas from flowing back to the working space of the electric furnace chamber, a flap valve is arranged on the main ventilation pipeline, in order to improve the strength of the flame arrester, the shell of the flame arrester is a cast steel shell, the filter element of the flame arrester is a main component for preventing flame from spreading, in order to improve the high temperature resistance, the overall strength and the filtering effect of the filter element, the filter element adopts a metal net filter element or a corrugated filter element, and the metal net filter element is formed by overlapping multiple layers of stainless steel or copper nets with the diameter of 0.23-0.315 mm.
