Embodiment Construction

[0030] For ease of understanding, combine 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 major modules, including: a feeding system, an annular sleeve jet nozzle 20, a cyclone dust collector 40, a rotating impeller inertial dust collector 50, a gas-water separator 60 and a thickener 70. Describe one by one below:

[0032] 1. Feeding system

[0033] The feeding system consists of two parts. The first part: the dust-containing gas conveying fan 10 transports the dust-containing gas into the inner nozzle 21 of the annular sleeve jet nozzle 20; the second part: the surface wettability activation agent passes through the dosing above the water storage tank 30 The funnel 32 is added to the water, initially dispersed and mixed under the stirring action of the impeller agitator 31, and fed into the outer annular nozzle 22 of the annular sleeve jet nozzl...

Abstract

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. The invention includes a dust-laden gas conveying fan, an annular sleeve jet nozzle, a water storage tank, a cyclone dust collector, a rotating impeller inertial dust removal device, a gas-water separator and a concentrator; the method of step-by-step dust removal and multiple dust removal ensures that each grain The complete removal of the first-grade dust, through the action of the annular sleeve jet nozzle, realizes the dust wetting and wrapping in the dusty gas; through the function of the cyclone dust collector itself, the larger dust and the mixed and wrapped particles of dust and water are removed; in the cyclone One or more sets of rotating impeller inertial dust removal devices are set in the central overflow channel of the dust collector for the capture and discharge of fine dust; a front baffle and a rear baffle are set at the inlet of the gas-water separator to ensure complete dust collection. remove. The invention has high dust removal efficiency, reliable and stable effect, uses general equipment of coal mine enterprises, and has low capital construction cost.

Description

Technical field [0001] The invention relates to the technical field of coal mine wet dust removal, in particular to a jet atomization type mine cyclone inertial dust collector and its use process. Background technique [0002] With the continuous improvement of the mechanized production level of coal mines, the dust production of mines and coal preparation plants has increased sharply, seriously threatening the safety of coal mines and the health of employees. At present, the most researched and used dust removal methods include 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 particles in the airflow to make them settle naturally for separation; inertial dust collector—when the direction of the airflow changes sharply, the dust particles are separated from the airflow due to their own inertial force; cyclone dust removal When the dust particles rotate wi...
