AI Technical Summary

Technical Problem

The existing smoke exhaust device needs to close the production line when replacing the filter equipment, resulting in economic losses and environmental pollution.

Method used

An environmentally friendly smoke exhaust device is designed, including a flue gas processor and a Y-shaped vent pipe. The ventilation path of the vent pipe is controlled through a valve, and the vent pipe is moved by an electric push rod and a sealed circular plate to reduce the impact of the flue gas treatment efficiency when replacing the filter equipment.

Benefits of technology

It realizes the minimization of economic losses and environmental pollution when replacing the filter equipment. By optimizing the design of the ventilator and the use of drive components, the normal operation of the rotary kiln is ensured.

Abstract

The utility model discloses an environmentally friendly smoke exhaust device for a rotary kiln roasting system, which relates to the field of smoke exhaust devices, including a smoke processor, wherein the interior of the smoke processor is divided into two areas, both of which are equipped with filtering equipment, and Y-shaped ventilation pipes are provided on both sides of the smoke processor, and the two ends of the ventilation pipes are respectively connected to the two areas of the smoke processor. The environmentally friendly smoke exhaust device for a rotary kiln roasting system described in the utility model is provided with ventilation pipes and valves. If it is necessary to replace the filtering equipment inside the smoke processor, the corresponding valve is closed at this time. Although the replacement has an impact on the efficiency of smoke treatment, the replacement time is short, so the impact can be ignored. When it is necessary to replace the filtering equipment at another position, the previously replaced valve is opened, and the current valve is closed, and the above operation is repeated to ensure that the rotary kiln can operate normally and minimize economic losses.
