Description
Technical Field
The utility model discloses a heating chamber and a heating system for smoke monitoring, and relates to the technical field of smoke detection.
Background
At present, the domestic monitoring of wet flue gas mostly relies on a sampling unit for pretreatment and centralized heating. And heating the flue gas to above 120 ℃, lifting the temperature of the flue gas to above the dew point, and then entering a measuring area for measurement in a constant-speed sampling mode. In the flue gas flowing process, heat loss causes temperature reduction, is easy to condense in a measuring area, influences measurement, and even pollutes a measuring system; and when heating the flue gas, the common heating chamber only utilizes the inboard heating of heating block to measure the flue gas, only utilizes the inside heating capacity of heating block, and is lower to the outside utilization ratio of heating block, and outside heat not only extravagant but also the loss in to measurement system, influences equipment ambient temperature, reduction equipment life.
In the existing smoke dust detection system, most of power gas is compressed air provided by an air compressor, specifically cold air with certain humidity, but the cold air enters a pneumatic conveyor to be mixed with heated smoke gas, so that the pneumatic conveyor is easy to be blocked, and the whole measurement system is affected.
