Abstract
The utility model relates to a secondary wind swirl intensity measuring device for a swirl combustor. The secondary wind swirl intensity measuring device comprises a fixed frame arranged in a nozzle of the swirl combustor, a centre rod arranged in the middle hole of a horizontal rod of the fixed frame, and a wing type rotator which is arranged in the middle of the centre rod and horizontally rotates around the centre rod; and an angle calibrated scale is arranged at a position of the centre rod close to the wing type rotator, and the left end part and side of the wing type rotator are respectively provided with a pressure gaging hole. The fixed frame and the centre rod in the measuring device provided by the utility model can accurately determine the centre position; the wing type rotator can generate great differential pressure, accurately indicates the rotation direction, reduces the pressure loss and stabilizes the flow field; the pressure gaging holes distributed on the wing type rotator can accurately measure the secondary wind speed, and improves the test precision and operability.
Description
Technical field
The utility model relates to a kind of turbulent burner secondary air swirl strength measurement mechanism.
Background technology
In the coal-burning boiler cold air dynamic field test of being furnished with turbulent burner; Need measure burner secondary air swirl strength, and in the existing measurement mechanism, equipment such as PIV particle imaging appearance and five holes probe are too high to environmental requirement; Cost an arm and a leg, be not suitable for operation at the scene; Hot-wire anemometer can record wind speed, records sense of rotation but can't indicate.
The utility model content
The utility model technical matters to be solved provide a kind of easy operating, easy to use, measure turbulent burner secondary air swirl strength measurement mechanism accurately.
The utility model adopts following technical scheme:
The utility model comprises the fixed mount that is arranged in the turbulent burner spout, be arranged on the center of circle bar in the fixed mount cross bar mider hole and be arranged on bar middle part, the center of circle and around the center of circle airfoil type spinner of bar left rotation and right rotation; The described airfoil type spinner position that on the bar of the center of circle, is close to is provided with the angle index chi; Bar upper end, described center of circle up-down adjustment in the hole of fixed mount cross bar is provided with the pressure gaging hole in the left part and the side of described airfoil type spinner.
The utility model good effect is following: fixed mount in the utility model and center of circle bar can accurately be confirmed home position; The airfoil type spinner can produce bigger differential pressure, accurately indicates rotation direction, reduces crushing, steady flow condition; The pressure gaging hole that is distributed on the airfoil type spinner is measured the secondary air wind speed accurately, improves test accuracy and operability, and the shape of airfoil type spinner can be optimized to reduce the disturbance to air-flow to greatest extent according to concrete occasion is concrete, improves measuring accuracy.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Mounting structure synoptic diagram when accompanying drawing 2 is measured for the utility model measurement mechanism.
In the accompanying drawings: 1 fixed mount, 2 angle index chis, 3 pressure gaging holes, 4 airfoil type spinners, 5 center of circle bars.
Embodiment
Like accompanying drawing 1, shown in 2; The utility model comprises the fixed mount 1 that is arranged in the turbulent burner spout, be arranged on the center of circle bar 5 in the fixed mount 1 cross bar mider hole and be arranged on center of circle bar 5 middle parts and around the center of circle airfoil type spinner 4 of bar 5 left rotation and right rotation; Described airfoil type spinner 4 positions that on center of circle bar 5, are close to are provided with angle index chi 2; Described center of circle bar 5 up-down adjustment in the hole of fixed mount 1 cross bar; In the left part of described airfoil type spinner 4 pressure gaging hole 3 is set, pressure gaging hole 3 is through being connected with electronic micro-manometer communicating pipe.
Like accompanying drawing 1, shown in 2; When measuring at the scene fixed mount 1 is positioned over turbulent burner overfire air port inwall, center of circle bar 5 can slide up and down at fixed mount 1 cross bar middle part, adjustment bar 5 positions, the center of circle; Make airfoil type spinner 4 place turbulent burner overfire air port centre position as far as possible; This moment, airfoil type spinner 4 directions were the secondary air direction, and this position can be divided into two components from the wind of overfire air port, and one is along spout pipeline axial direction; One is to be the tangential direction in the center of circle with spout pipeline axle center, and angle is the angle of secondary air direction and spout pipeline axial direction shown in this moment angle index chi 2.Can record from the pressure gaging hole 3 on the airfoil type spinner 4 through electronic micro-manometer simultaneously and record the secondary air wind speed; And through angle index chi 2 indication rotation directions acquisition secondary air rotation direction; According to total wind speed of gained and rotation direction, can try to achieve the size of two components respectively, finally try to achieve the secondary air swirl strength; Wherein the shape of airfoil type spinner 4 can be optimized to reduce the disturbance to air-flow to greatest extent according to concrete occasion is concrete, improves measuring accuracy.
Fixed mount 1 in the utility model and center of circle bar can accurately be confirmed home position; Airfoil type spinner 4 can produce bigger differential pressure, accurately indicates rotation direction, reduces crushing, steady flow condition; The pressure gaging hole that is distributed on the airfoil type spinner is measured the secondary air wind speed accurately, improves test accuracy and operability.
