Description of drawings
Fig. 1 is venturi type gas mixer general assembly drawing.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but described embodiment is not intended to limit protection domain of the present utility model.
Fig. 1 is venturi type gas mixer general assembly schematic diagram.This gas mixer comprises the first premixed gas input port 1, the second premixed gas input port 2, gas mixer chamber 3, static mixer 4, mist delivery outlet 5.In one embodiment, use supporting bolt that the first flange 6 is connected with the pipe flange of the first premixed gas, and between two flanges, install gasket seal additional; Use supporting bolt that the second flange 7 is connected with the pipe flange of the second premixed gas, and between two flanges, install gasket seal additional; Use supporting bolt that three-flange 8 is connected with the pipe flange of mist, and between two flanges, install gasket seal additional, so that whole gas mixer becomes the integral body of a connection.
The first premixed gas is by premixed gas input port 1 input gas mixer chamber 3, the second premixed gas is by premixed gas input port 2 input gas mixer chambers 3, two strands of gases are located cross jet in the input port, thereby carry out in gas mixer chamber 3 preliminary mixing of the first time.The preliminary gas that mixes enters static mixer 4 under pressure subsequently, stack consists of static mixer 4 as mixed cell (the corrugated plating angle is 90 °) by the several layers of different corrugated plating of width, and every layer flows to into the staggered horizontal and vertical of opposite form by the adjacent layer runner and installs.After the preliminary gas that mixes enters static mixer 4, different arranged direction according to static mixer 4 interior mixed cells flow, the circulating area that this static mixer 4 forms constantly changes, so velocity field is radially also no longer according to concentrically ringed formal distribution, but fully multilated.Gas is divided into multiply, then flows along wavy channel, washes away at a certain angle wall near wall, and the boundary layer is destroyed, attenuate thus, thereby improves the exchange capability of heat of wall and near gas.Because the variation of mixing chamber internal gas pressure, gas confluxes towards tube hub from left and right wall, is then shunted up and down by tube hub, and then gas confluxes to tube hub from upper and lower wall, then by tube hub to left and right shunting, the output of confluxing from upper and lower wall to tube hub again.Because the effect of mixed cell, when making gas and left-handed, the time and dextrorotation constantly changes the mixer direction that flows, not only center gas is pushed to periphery, and is pushed peripheral gas to center, thereby cause good radially mixed effect.Meanwhile, the turning effort of gas self also can occur on the interface of adjacent component junction, and this perfect radial circular flow immixture makes gas obtain the purpose that mixes.By being fixed on the mixed cell internals in the static mixer 4, make two bursts of γ-ray emission cuttings, shear, rotate and again mix, gap at static mixer, gas is also just periodically made point source or the some flow and mobile along the circulation of wall of above-mentioned this approximate ideal gas, this just makes fluid produce radially and circumferential flow, make near the fluid of core flow and wall constantly carry out momentum and energy exchange, reach constantly all purposes of oxidizing gases.After two kinds of full and uniform mixing of gas, via 5 outputs of mist delivery outlet, thereby obtain uniform and stable mist.
