Abstract

The utility model relates to a jet flux dust collector, which is composed of a jet pipe, a whirlwind cylinder, a dust collection box and a return pipe. Dusty gases enter the jet pipe and form high speed jet as more than 90m/s so as to be jetted. Dust particles enter the dust collection box with the fast forward beaming efflux. Then the dust particles are unloaded through an ash discharging opening and lighter gases are separated from others. The lighter gases are delivered in the reverse direction through the whirlwind cylinder. Meanwhile, in order to reduce airflow resistance of entering the dust collection box, part of dusty gases return the jet pipe through the return pipe. Dust collectors can be connected in series, connected in parallel and connected in series and in parallel for use. The utility model has the advantages of better dust collection effect, simple structure, power saving, low running cost, free from dust concentration and size limitation of exhaust air quantity, etc.

Description

Penetrate cycle stream dust-precipitator

The utility model relates to the cleaner in the environmental protection field, and dust-precipitator is flowed in specifically a kind of cycle of penetrating that is used for dust collection.

In production processes such as pulverizing, grinding, the workshop dust from flying, now use the more electrostatic precipitator that has, cleaners such as rotary counter-blowing sack cleaner because on-site airborne dust point is many, need be adorned many dedusters, and above-mentioned deduster volume is big, price is high, complex structure, operating cost is many after coming into operation, fault is many, and general producer is beyond affordability.

The purpose of this utility model just provides a kind of simple in structure, and operating cost is low, does not have maintenance cost substantially, and dust-precipitator is flowed in the cycle of penetrating that dust collection effect is good.

The utility model is achieved in that by what jet pipe, whirl cylinder, disposal box, return duct were formed penetrates cycle stream dust-precipitator, jet pipe is fixed on the upper end of whirl cylinder by flange, the lower end of whirl cylinder links to each other with disposal box, and return duct is connected with disposal box with jet pipe respectively.Dusty gas enters jet pipe, dust granules along with rapidly forward cluster fluidic and enter disposal box, draw off by ash discharging hole.

Further specify the utility model below in conjunction with drawings and Examples:

Fig. 1 is the utility model general structure schematic diagram;

Fig. 2 is the multilevel hierarchy schematic diagram of Fig. 1.

As Fig. 1, shown in Figure 2, dusty gas enters jet pipe 1, along with progressively dwindling of jet pipe 1 cone, pressure increases thereupon, gas flow rate is accelerated thereupon, finally form high-speed jet and spray, make gas be applied to the power on the dust granules and keep the air throughput direction to form cluster fluidic rapidly forward, along with progressively dwindling of whirl cylinder 2 cones with the rapid-result degree of＞90 meter per seconds, its flow velocity is more and more faster, dust granules enters disposal box 3 thereupon concentrating, and enters the cluster fluidic of disposal box 3, because the increase of cross section, air velocity here descends suddenly, make the very fast sedimentation of dust granules, material is concentrated in this, draws off by ash discharging hole; Simultaneously, for the gas-flow resistance that minimizing enters disposal box 3, draw return duct 4 in the upper end of disposal box 3, be connected on dusty gas and enter on the pipeline of jet pipe 1, make it that air-flow reciprocation cycle about 15% be arranged, also dotted line equally is connected on next stage and enters on the pipeline of dust-precipitator as shown in Figure 2; Cluster fluidic rapidly forward in, lighter air is therefrom separated, and isolated gas is sent with opposite direction rotation, the flow velocity of this moment reduces more than 85%, the parts of fine particle collides from eddy flow is thrown to the eddy flow barrel, and along the wall landing, and not separated dust-contained airflow enters the next stage dust-precipitator, continue to separate, repeat until meeting the dedusting requirement with this.

Adopt the utility model, can be according to the size of dust content and exhausted air quantity, do primary dust removing, also can two above series, parallel, connection in series-parallel use, promptly form multistage dedusting, also can be horizontal, vertical, install arbitrarily, if waste gas humidity is big according to field position, with dust-exhausting port is good down, prevents line clogging.Therefore, the utlity model has simple in structure, be convenient to install, operating cost is low, does not have maintenance cost substantially, fault is few, the running rate height, economize on electricity, and high temperature resistant, corrosion-resistant and be not subjected to the restriction of dust concentration, exhausted air quantity size, characteristics such as good dedusting effect are the ideal products that enterprise's dedusting updates.

Claims

A kind of cycle stream dust-precipitator of penetrating, it is characterized in that: form by jet pipe (1), whirl cylinder (2), disposal box (3), return duct (4), jet pipe (1) is fixed on the upper end of whirl cylinder (2) by flange, the lower end of whirl cylinder (2) and disposal box (3) join, and return duct (4) is connected with disposal box (3) with jet pipe (1) respectively.
