Problems solved by technology

[0009] Compared with the first type of dust collector, the gas injection device can relatively increase the injection pressure and gas volume of the gas, but it has the following disadvantages: First, because the injection direction of the annular gas injection port of the gas injection device is almost perpendicular to the inner wall of the cylinder , so most of the compressed gas sprays each other to offset part of its pressure and energy, and it is difficult for some external air to penetrate the mutually sprayed gas and flow into the cylinder; The cylinder is vertically vertical, so that when external air is sucked in, a part of the external air is blocked by the extension of the cover and reflected to the outside, thus reducing the amount of gas inhaled; The gas transmission nozzle of this kind of gas transmission nozzle blocks the external gas that is sucked down, thereby also reducing the amount of gas sucked; Fourth, because the gas flow direction of this gas injection device is relatively single, that is, the gas only flows downward There is no power to flow around, so the dust and pollutant particles attached to the side surface of the filter bag cannot be effectively removed
Therefore, the gas injection device with the above structure does not achieve the desired effect

Embodiment 1

[0031] combine Figure 4 and Figure 5 To illustrate the excellent function of the gas injection device provided by the present invention.

[0032] Compressed gas enters the annular gas storage chamber 2 through the gas supply port 6, and is sprayed onto the inner wall of the cylinder body 1 through the annular gas injection port 5 at high speed, while the negative pressure generated by the external gas flowing downward at a high speed is suppressed. Inhaled into the cylinder 1, the gas sprayed onto the inner wall of the cylinder 1 forms a downward spiral flow relative to the longitudinal direction of the cylinder 1 according to the wings 7 provided on the inner wall of the cylinder 1. The spiral flow passes through the lower part of the cylinder 1. The Venturi tube flows into the filter bag. Compared with the existing gas injection device, the gas injection device of the present invention can more easily inhale external gas and interact with the Venturi tube due to the downwa...

Embodiment 2

[0034] This embodiment is made up of the structure in Implementation 1, but wherein, the angle α adopted by the annular gas injection port 5 is 80°, and has six wings 7 which are evenly distributed relative to the cylinder 1, and the adopted inclination angle β is 15°. The end is designed as a circular arc transition, and a compressed gas inlet 6 is selected, but its number can be increased or decreased as required.

[0035] To sum up, the gas injection device provided by the present invention reduces the energy loss caused by the compressed gas spraying against each other by changing the injection direction of the annular gas injection port, and increases the amount of inflowing gas. Moreover, the design on the surface of the cylinder There are wings that make the gas spiral downward, thereby improving the dust removal efficiency of the dust collector and saving energy.

Abstract

The invention discloses a gas injection device, comprising a cylinder and an annular gas storage chamber formed on the periphery of the top end of the cylinder, and the annular gas storage chamber, which is composed of an annular casing and an annular cover, is provided with a gas supply port and a gas injection port formed by surrounding the cylinder inwards, the invention is characterized in that the gas injection port is composed of an inner side edge of the annular cover and a jointing portion where the top end of the cylinder is jointed with the annular shell, wherein the inner side edgeof the annular cover inclines at a predetermined angle towards the interior of the cylinder for extension until the inner diameter of the annular cover is smaller than that of the cylinder. And the inner wall of the cylinder is provided with a plurality of wings which longitudinally incline at a predetermined angle to the cylinder. Once the injected gas flows through the wings, a gas flow, which flows downwards and spirally with respect to the longitudinal direction of the cylinder, is formed within the cylinder by the gas in accordance with formation direction of the wings, thereby increasing gas amount and pressure of the gas flow and more efficiently removing dusts attached to the lateral surface of a filter bag, consequently the dust removal efficiency can be enhanced.

Description

technical field [0001] The invention relates to a gas injection device, in particular to a gas injection device for dust removal equipment. Background technique [0002] The gas injection device is a device suitable for dust collectors that forms a large volume of low-pressure gas flow by supplying a small amount of compressed gas. Dust collectors are generally installed in workplaces that discharge a large amount of dust, and then capture dust in the air to discharge purified air to the outside. [0003] figure 1 It is a schematic diagram of the structure and working principle of the existing dust removal equipment. [0004] Such as figure 1 As shown, the existing dust collector is composed of a housing and a plurality of filter bags 1-1 inside, the lower side of the housing is designed with an air inlet for sucking polluted air, and an example of the upper part of the housing is designed for discharging The exhaust port of the purified air, the upper part of the filter...
