Embodiment Construction

[0030] For ease of understanding, combined here Figure 1-4 , the specific embodiments of the present invention are further described as follows:

[0031] The specific components of the present invention are divided into several modules, including: feeding system, annular sleeve jet nozzle 20, cyclone dust collector 40, rotary impeller inertial dust removal device 50, gas-water separator 60 and concentrator 70. Describe them one by one below:

[0032] 1. Feeding system

[0033] The feeding system consists of two parts, the first part: the dust-laden gas conveying fan 10 conveys the dust-laden gas into the inner nozzle 21 of the annular sleeve jet nozzle 20; The funnel 32 is added to the water, under the agitation of the impeller agitator 31, it is preliminarily dispersed and mixed, and fed into the outer annular nozzle 22 of the annular sleeve jet nozzle 20 by the pump 33 in a tangential feeding mode.

[0034] 2. Annular sleeve jet nozzle

[0035] The inner nozzle 21 of th...

Abstract

The invention relates to the technical field of wet dust removal of coal mines, in particular to a jet atomization type mining rotational-flow inertial dust remover and application process thereof. The jet atomization type mining rotational-flow inertial dust remover comprises a dusty gas conveying fan, an annular sleeve jet nozzle, a water storage tank, a rotational-flow dust remover, rotary impeller inertial dust removing devices, a gas-water separator and a concentrator. The jet atomization type mining rotational-flow inertial dust remover has the advantages that dust of various particle sizes can be removed by gradual dust removing and multiple dust removing, and the dust in the dusty gas can be moistened and wrapped by the annular sleeve jet nozzle; large dust and dust-water-mixed wrapped particles can be removed by the rotational-flow dust remover; one or more rotary impeller inertial dust removing devices are arranged in the central overflow channel of the rotational-flow dust remover and used for capturing and discharging fine dust; a front retaining plate and a rear retaining plate are arranged at the inlet of the gas-water separator to guarantee the complete removing of dust. The jet atomization type mining rotational-flow inertial dust remover which uses universal equipment of coal mine enterprises is high in dust removing efficiency, reliable and stable in effect and low in capital construction cost.

Description

technical field [0001] The invention relates to the technical field of wet dust removal in coal mines, in particular to a jet atomization type mine cyclone inertial dust collector and its application process. Background technique [0002] With the continuous improvement of the mechanized production level of coal mines, the amount of dust produced in mines and coal preparation plants has increased sharply, seriously threatening the safety of coal mine production and the health of workers. At present, there are many dust removal methods researched and used, including mechanical dust removal, wet dust removal, filter dust removal, and electric dust removal. Mechanical dust removal equipment includes: Gravity settler—uses the gravity of the particulate matter in the airflow to make it settle naturally for separation; Inertial dust collector—When the airflow direction changes sharply, the dust particles are separated from the airflow due to their own inertial force; Cyclone dust ...
