Problems solved by technology
Through the dust removal experiment, the dust removal efficiency of fine particles can be deeply explored. Generally, an aerosol fume generating device is used to produce dust-laden gas, but the concentration of the dust-laden gas obtained is unstable. , and cannot accurately simulate the actual smoke and dust composition; and the ordinary feeder cannot be applied to the experiment, cannot effectively form a uniform dust-containing gas, and does not meet the requirements of specific smoke and dust micro-transportation

Embodiment Construction
[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0017] like figure 1 As shown, a dust-containing gas generating device includes an air supply pipe 1 and an ash delivery mechanism 2. The ash delivery mechanism 2 is arranged inside the air supply pipe 1. The ash delivery mechanism 2 consists of an ash tank 4, a delivery pipe 3, a first, The second miniature bearing, the auger 5, the shaft coupling 7 and the reduction motor 8 are composed. The bottom of the ash tank 4 passes through the side wall of the conveying pipe 3 and communicates with the inside of the conveying pipe 3, and the ash inlet of the ash tank 4 passes through the conveying pipe. The side wall of the air duct 1 is arranged on the outside of the air supply duct 1; the front and rear ends of the auger 5 are respectively arranged inside the conveying pipe 3 through the first and second miniature bearings, and the auger 5...

Abstract
A dust-containing gas generating apparatus belongs to the technical field of dedusting experiments, and is used to long uniformly stably generate dust-containing gas with assigned concentration values. The apparatus provided by the invention not only helps to realize the uniform microscale transportation of specific dust and guarantee the effective formation of the dust-containing gas, but also helps to realize the accurate adjusting on the concentration of the dust-containing gas and guarantee the stable long-time performing of experiments. The apparatus comprises a blast pipe and a dust sending mechanism arranged in the blast pipe; the dust sending mechanism consists of a dust groove, a conveying pipe, a bearing, an auger, a shaft coupling and a deceleration motor; the interior of the conveying pipe is communicated with the exterior of the blast pipe via the dust groove; the auger is arranged in the conveying pipe via the bearing; and the auger is connected with the deceleration motor via the shaft coupling.
Description
technical field [0001] The invention belongs to the technical field of dust removal experiments, and in particular relates to a dust-containing gas generating device, which is used to uniformly and stably generate dust-containing gas with a specified concentration value for a long time. Background technique [0002] At present, coal smoke from fossil fuel combustion, dust and metal dust from industrial production, and cement dust from construction have caused serious air pollution, especially the fine particles in smoke dust, which stay in the atmosphere for a long time , and the long migration distance is the main factor causing haze weather. At the same time, due to the increasing scarcity of fuel resources such as coal and fossils, recycling the high-temperature waste heat and waste energy in the industrial production process can effectively save fuel resources and alleviate environmental pollution and other problems. Effective dust removal for high-temperature gas is an...
