Problems solved by technology

In the past, some electric furnace flue gas combustion and settling chambers directly used concrete structures, and some used water-cooled coil structures. There is no automatic control device for the concentration of CO, and the dust settlement effect is poor, and the heat of the flue gas cannot be effectively recovered

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 with figure 2 As shown, it is a structural schematic diagram of the present invention. The self-controlled electric furnace flue gas combustion settling chamber includes a shell 1, a baffle plate 2, a support 5, a burner 3, a flue gas inlet 13, a flue gas outlet 9, and an ash discharge port 7 , Rapper 6, CO concentration monitoring device 10 and A / D converter 11. The cross-section of the shell 1 is circular, which can effectively eliminate the dead angle existing in the shell of the traditional structure and avoid the phenomenon of CO accumulation. The shell 1 is provided with a maintenance manhole 4, and the upper and lower parts of the shell 1 are set as Taper structure, the inner wall of the shell is equipped with vaporization cooling coil or water-cooled heat exchange tube. When the vaporization cooling coil structure is adopted, it can absorb the...

Abstract

The invention relates to an automatic control electric furnace flue gas combustion settling chamber. The chamber consists of a shell, baffles, supports, combustors, a flue gas inlet, a flue gas outlet, an ash discharge port, a vibrator, a CO concentration monitoring device and an analog-digital (A/D) converter, wherein the cross section of the shell is round; reducing ports are formed on the upper part and the lower part of the shell; the baffles are positioned in and welded with the shell; the combustors are arranged on the inner wall of the shell; one combustor is arranged between every two adjacent baffles; the CO concentration monitoring device is arranged at the flue gas outlet and can detect the concentration of CO at the flue gas outlet; and an automatic control device automatically changes the opening of a valve at the flue gas inlet, so that the amount of air mixed in the flue gas inlet is automatically changed, and the CO is fully combusted. The automatic control electric furnace flue gas combustion settling chamber can monitor the content of the CO in discharged flue gas, ensures environmental safety and is high in regulation performance and easy and convenient to operate, and operation is automatically controlled.

Description

technical field [0001] The invention relates to a self-controlled electric furnace flue gas combustion settling chamber, in particular to an electric furnace flue gas combustion settling chamber which automatically controls the amount of air mixed into the flue gas inlet, and belongs to the field of separation technology. Background technique [0002] The electric furnace flue gas combustion settling chamber is a device that removes large particles of dust in the flue gas and partially burns CO at the same time. In the past, some electric furnace flue gas combustion and settling chambers directly used concrete structures, and some used water-cooled coil structures. There is no automatic control device for the concentration of CO, and the dust settlement effect is poor, and the heat of the flue gas cannot be effectively recovered. [0003] The present invention aims to overcome the deficiencies of the existing electric furnace flue gas combustion settling chamber technology,...
