Embodiment Construction

[0026] Such as figure 1 As shown, a device for improving the efficiency of a single-stage high-power hood, at least including: hood 1, axial fan 2, gear box 4, motor 5, hood 1, axial fan 2, gear box 4, motor 5 They are respectively fixed on the base 3, and the hood 1, the axial flow fan 2, the gear box 4, and the motor 5 are coaxially connected in turn from left to right;

[0027] When working, the smoke machine 1 performs work through the high-temperature and high-pressure flue gas in the oil refining process, and the high-temperature flue gas (about 680°C) with pressure (about 0.3 MPa) is rectified by the intake casing 104 and the stator blade 106 of the smoke machine 1 , evenly enters the moving blade 115-3, expands to do work, and pushes the rotor assembly 115 of the cigarette machine 1 to rotate; at the same time, the temperature and pressure of the flue gas decrease, and the heat energy and pressure energy are converted into mechanical energy; the rotor assembly 115 of t...

Abstract

The invention relates to a device for improving the efficiency of a single-stage high-power hood, which is characterized in that it at least includes: a hood, an axial fan, a gear box, and a motor, and the hood, the axial fan, the gear box, and the motor are respectively fixed on the base Above, the hood, axial flow fan, gear box, and motor are connected coaxially from left to right in sequence; the output of the rotor assembly of the hood is connected to the motor shaft through the gear box. The invention has the characteristics of safety, reliability and high efficiency.

Description

technical field [0001] The invention relates to flue gas energy recovery equipment in petrochemical oil refinery catalysis and cracking - a flue gas turbine, in particular to a device for improving the efficiency of a single-stage high-power smoke machine. Background technique [0002] Domestically, the TP type produced by Xihang and the LY type smoke machine produced by Lanlian with axial intake, radial exhaust and cantilever support structure are the mainstream. At present, the efficiency of domestic single-stage hoods is generally maintained at about 79%, which is still far from the expected efficiency of users. Therefore, on the premise of ensuring the safe and reliable operation of the hood, optimizing and improving the efficiency of the single-stage high-power hood is an important issue to be solved urgently. [0003] The two major domestic manufacturers have actively explored in optimizing and improving the efficiency of single-stage high-power hoods. The TP type ho...
