Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0014] refer to figure 1 As shown, the present invention provides a novel small flue air induction system, which includes a furnace 1, a flue 2, and a jet air inducer 3 connected in sequence, and the control end of the jet air inducer 3 (i.e., the inlet end of the working gas source) The connected air heating control unit, and the closed-loop furnace pressure control unit connected between the furnace 1 and the control end of the jet air inducer 3; wherein, the air heating control unit heats the external compressed air and outputs it to the jet air inducer 3 , so that the flue gas will not condense at the flue mouth of the small flue, and the closed-loop furnace pressure control unit adjusts the working pressure of the jet air inducer 3 in real time according to the pres...

Abstract

The invention discloses a novel small-flue induced draught system. The novel small-flue induced draught system comprises a hearth flue, a jet flow induced draught device, an air heating control unit connected with the control end of the jet flow induced draught device, and a closed loop hearth pressure control unit connected between a hearth and the control end of the jet flow induced draught device, wherein the hearth flue and the jet flow induced draught device are connected in sequence. The air heating control unit heats external compressed air and outputs the air to the jet flow induced draught device, and the closed loop hearth pressure control unit adjusts working pressure of the jet flow induced draught device according to the hearth pressure in real time. The novel small-flue induced draught system uses the compressed air of the air heating control unit as a power and uses the jet flow induced draught device to perform induced draught to a small flue, and the problem that the system is free of high temperature resistance, blades are abraded and dust sticks on the blades by means of an induced draught motor is solved. In addition, the closed loop hearth pressure control unit can adjust the working pressure of the jet flow induced draught device in real time.

Description

technical field [0001] The present invention relates to a flue-induced air technology, and more specifically, to a novel small flue-induced air system. Background technique [0002] For flue induced draft, generally all adopt the mode of installing induced draft motor at flue exit in the prior art. But for the small flue, if the installation of the induced draft motor is adopted, there are the following difficulties: 1. Because the diameter of the small flue is small and the flue is short, the flue gas in the flue flows quickly, and the temperature of the flue gas at the outlet is high. The use of an induced draft motor will bring difficulties to the temperature resistance and long-term use of the motor; 2. The speed of the flue gas is fast, and the blades of the induced draft motor are greatly worn, which affects the long-term use of the motor; 3. The dust in the flue gas is not filtered completely , Dust and condensed water will adhere and deposit on the fan blades, affec...
