Abstract

The invention provides an inlet temperature control device of a dust collector of a production line. The inlet temperature control device mainly comprises a cold air electric valve, a temperature sensor and a temperature PLC (programmable logic control) system. The temperature PLC system automatically adjusts opening of the cold air electric valve according to comparison of set values with temperature signals transmitted by the temperature sensor, so that air can flow into a pipeline and is mixed with flue gas, and the temperature of gas which flows into the dust collector can be reduced. The inlet temperature control device has the advantages that the inlet temperature control device can run automatically, the temperature of the gas which flows into the dust collector can be precisely controlled in real time, running conditions of the dust collector can be met, and the inlet temperature control device is high in automation degree and can be operated safely and conveniently.

Description

Technical field [0001] The invention relates to the technical field of cement production, in particular to a temperature control device for the inlet of a dust collector of a production line. Background technique [0002] In the dry cement production technology, the preheater will generate a large amount of high-temperature flue gas, which contains a large amount of cement clinker dust. Therefore, a large bag dust collector or electric dust collector is installed at the end of the kiln. Separate and settle cement clinker dust. However, the dust collector has very high requirements for the temperature of the flue gas entering it, and the temperature must be controlled at about 180°C, otherwise it will damage the internal components of the dust collector and reduce its service life. Therefore, a cold air valve is often opened on the flue gas pipe before entering the dust collector to achieve the purpose of reducing the temperature by mixing the flue gas with the outside air. Howe...
