Rapid combustion chamber temperature adjusting device

Abstract

The invention relates to a rapid combustion chamber temperature adjusting device which comprise a shell, wherein a high-temperature flue gas inlet is formed in the shell; a high-temperature flue gas adjusting valve is arranged at the inner end of the high-temperature flue gas inlet; a low-temperature flue gas inlet is formed in the shell beside the high-temperature flue gas inlet; a mixed flue gasoutlet is formed in the shell beside the high-temperature flue gas inlet; a uniform low-temperature flue gas distributor is arranged on the shell between the low-temperature flue gas inlet and the high-temperature flue gas adjusting valve; a guide mechanism is arranged inside the shell between the mixed flue gas outlet and the high-temperature flue gas adjusting valve; and a temperature controller is arranged outside the shell. By adopting the device, heat of a combustion chamber can be rapidly released, metals can be effectively prevented from high-temperature oxidation, the energy consumption can be reduced, and the service life can be prolonged.

Description

technical field [0001] The invention relates to a temperature regulating device, in particular to a combustion chamber temperature regulating device. Background technique [0002] When the general regenerative incinerator treats organic waste gas, the concentration of organic matter in the waste gas is limited to less than 3000mg / Nm 3 About (equivalent to exhaust gas calorific value is about 18KCal / Nm 3 ); For those whose concentration is higher than the treatment limit, direct incineration with higher energy consumption is generally used. In order to increase the concentration of organic waste gas treated by the regenerative incinerator, it is necessary to direct the superheated heat of the system through the high temperature regulating valve of the combustion chamber. High-temperature flue gas emission, thereby increasing the concentration of organic waste gas treated by the regenerative incinerator to 10000mg / Nm 3 About (equivalent to exhaust gas calorific value is abou...

AI Technical Summary

Problems solved by technology

Since the amount of flue gas emitted by this part of the high-temperature flue gas is generally very small, there is no use value of waste heat, so there is no flue gas cooling measure, and this part of high-temperature flue gas can only be directly controlled by the high-temperature metal regulating valve installed in the combustion chamber. High-temperature metal control valves work directly at a high temperature of 900-1000 °C, and the shortened service life of high-temperature-resistant metal valves caused by high-temperature oxidation of metals has always troubled us.
