The device disclosed by the utility model is mounted on a cyclone dust remover and forms series connection with the cyclone dust remover so that the air, water mist and fine dust are sufficiently mixed and the dust of different particle sizes is graded; relatively high dust removal efficiency is realized against the dust and particularly fine dust (<10 microns). The device can be widely applied to the purification of the dust-containing air at the places for crushing, screening, transferring and the like in earth surface purification of a dressing plant, and also can be applied to the airflow purification of underground working surfaces and the purification of dust-containing air in the underground crushing chamber, draw shaft ore loading/unloading, underground ore bin and secondary crushing roadway.
Description
Technical field
The utility model relates to a kind of dust arrester, especially relates to a kind of high-pressure fog injection dust arrester, for being installed on cyclone dust, forms and connects, to improve the efficiency of deduster with cyclone dust.
Background technology
Dust pollution is stubborn problem in industrial operations environmental pollution always.According to statistics at present in the world 70% pneumoconiosis patients in China.By 2009, China had Pneumoconiosis Patients approximately more than 60 ten thousand people, by 40,000 yuan of calculating of the annual cost of every example, and more than 240 hundred million yuan of the annual therefore direct economic losses in the whole nation.In addition, the annual newly-increased Pneumoconiosis Cases in the whole nation causes new economic loss also in the speed increment with annual 600000000 yuan, brings heavy financial burden to labourer, employing unit and country.In addition, according to the parties concerned, estimate roughly, the direct economic loss that China causes because of occupational disease, industrial accident every year approximately reaches 1,000 hundred million yuan, and indirect economic loss approximately reaches 2,000 hundred million yuan.
Occupational hazards Yi Bei industry circle that dust in mine causes is fully realized, in particularly opencast perforation of mining, reprinting, transportation and ore dressing crushing and screening workshop, the art production process such as the conveying of material, transhipment, fragmentation, screening all can produce dust.In order to create a good working environment to workman; reduce the probability of happening of occupational disease; carry out the treating flour dust in the production process of mine; the dust that produces dirt pits is effectively controlled; not diffusion towards periphery; fundamentally eliminate dust harzard, realize exploitation of mineral resources and ecological environmental protection coordinated development.
For the improvement of dust pollution, mainly by collecting or adopting limited means to reduce airborne solid grain contamination content, realize.When required airflow reaches requirement, deduster is a critical component, and deduster effect quality directly affects the improvement of environmental quality.
Chinese patent ZL200920037396 discloses a kind of cyclone dust of quantity-adjustable, it comprises a dust cleaning case casing, by upper and lower holder, be separated into into, return air chamber and nowel chamber in this dust cleaning case casing, and form and have into, return air interface at the sidepiece of this dust cleaning case casing, air intake interface communicates with air-inlet cavity, and return air interface communicates with return air chamber, the bottom of dust cleaning case casing extends to form the ash bucket that goes out communicating with described nowel chamber.This cyclone dust is relatively simple for structure, but is not suitable for the classification of the dust of wide particle diameter to process, particularly lower to the efficiency of dust collection of fine dust (<10 μ m).
Summary of the invention
The purpose of this utility model is exactly the problems referred to above that exist in existing dedusting technology device, and provide, a kind of efficiency of dust collection is high, the experimental study of air ejector with high-pressure spray for dust suppression to fine dust good dedusting effect.
For realizing above-mentioned purpose of the present utility model, a kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model by the following technical solutions:
A kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model consists of Gas inlet tube, feed pipe, trunnion, the flap that is arranged in trunnion, and the water side of feed pipe is provided with shower nozzle, and it is corresponding with trunnion that shower nozzle is positioned at the middle part of Gas inlet tube.
For ease of regulating the size of water smoke, described shower nozzle is comprised of rotatable core body and housing two parts, and housing is threaded onto on core body.The nozzle of described shower nozzle adopts Venturi nozzle, and atomizing effect is good.
A kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model adopts pressure-air to impact the flap-air distributor in trunnion, makes air, water smoke, the abundant mixed collection of fine dust.
A kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model adopts after technique scheme, has the following advantages:
1. be installed on cyclone dust, form and connect with cyclone dust, air, water smoke, fine dust are fully mixed, the dust classification processing to different-grain diameter, to dust particularly fine dust (<10 μ m) have higher efficiency of dust collection.
2. water consumption is low, adopts Venturi nozzle, and high-speed gas atomization is effective, and nozzle does not stop up.
3. dust removal performance is excellent, and resistance is low.Running resistance is a kind of desirable update technical equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model;
Reference numeral is: 1-Gas inlet tube; 2-feed pipe; 3-flap; 4-shower nozzle; 5-trunnion.
The specific embodiment
For further describing the utility model, below in conjunction with drawings and Examples, a kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model is described in further details.
The structural representation of a kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model is as shown in Figure 1 found out, a kind of experimental study of air ejector with high-pressure spray for dust suppression of the utility model is to be constituted by Gas inlet tube 1, feed pipe 2, trunnion 5, the flap 3 that is arranged in trunnion 5, the water side of feed pipe 2 is provided with shower nozzle 4, and it is corresponding with trunnion 5 that shower nozzle 4 is positioned at the middle part of Gas inlet tube 1.Described shower nozzle 4 is comprised of rotatable core body and housing two parts, and housing is threaded onto on core body.The nozzle of shower nozzle 4 adopts Venturi nozzle.Flap 3 changes airflow direction, accelerates air velocity and changes, and improves dust and water smoke collision contact probability, improves aggregation efficiency.
