Abstract

The utility model relates to a flue gas purifying device for graded recovery of expanded perlite in a shaft kiln, mainly comprising a primary cyclone dust collector, an air blower, a bin, a material conveying pipeline, a discharging valve and an induced draft fan, wherein a bag type dust collector is arranged behind the induced draft fan. In the flue gas purifying device, by effective graded recovery of granular and powdery expanded perlite, the content of the powdery expanded perlite in the granular perlite is reduced, the quality of the granular perlite is improved, the emission of dust-free fresh air and standard emission of purified flue gas are realized, the environmental pollution is obviously improved, all the collected powdery perlite collected by adopting the flue gas purifying device can be recovered and sold, so that the economic benefit is increased.

Description

Smoke eliminator is reclaimed in a kind of shaft kiln expanded perlite classification

Technical field

The utility model relates to a kind of shaft kiln expanded perlite classification and reclaims smoke eliminator.

Background technology

Present domestic perlite production line adopts three two stage cyclone dedusters to collect perlite product as shown in Figure 1, simultaneously flue gas is purified, because perlitic proportion has only 0.25, adopts the cyclone dust collectors dust-collecting efficiency very low.The strong perlite of a large amount of powder is entrained in the finished product, and a part enters atmosphere with flue gas, has both influenced product quality, has wasted resource, has polluted environment again.

Summary of the invention

The purpose of this utility model is to overcome deficiency of the prior art, thereby provides a kind of second level cyclone dust collectors and feed bin cyclone dust collectors cancelled to use the shaft kiln expanded perlite classification of sack cleaner instead and reclaim smoke eliminator.

Smoke eliminator is reclaimed in a kind of shaft kiln expanded perlite classification, mainly comprises one-level cyclone dust collectors, air blast, feed bin, material transport pipeline, bleeder valve and air-introduced machine; Behind described air-introduced machine, be provided with a sack cleaner.

Adopt the beneficial effect of technique scheme to be:

1, the utility model has reduced the powdery perlite content in the granular perlite by granular, the perlitic effective classification of powdery are reclaimed, and improves the perlitic quality of particle, has realized dustless pure qi (oxygen) discharging, and environmental pollution obviously improves.

2, the powdery perlite that adopts the utility model to collect can all reclaim sale, has increased economic benefit.

3, the utility model has been realized the purification qualified discharge of flue gas, and environment has obtained obvious improvement.

Description of drawings

Fig. 1 is the block diagram of prior art;

Fig. 2 is the block diagram that smoke eliminator is reclaimed in the classification of the utility model shaft kiln expanded perlite.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

The utility model has been cancelled second cyclone dust extractor and the feed bin cyclone dust collectors in the former purifier. and the granular perlite that the one-level cyclone dust collectors are collected enters feed bin by air blast by material conveying pipe; Contain the perlitic gas of a large amount of powderies from the discharge of one-level cyclone dust collectors blast pipe and enter sack cleaner with the collection of powdery perlite, enter atmosphere after the purification in the effect of air-introduced machine.The perlitic gas of powdery dedusting that contains that feed bin is discharged extracts and enters sack cleaner out under the effect of air-introduced machine, thereby collects the powdery perlite.

The newly-increased sack cleaner of the utility model can adopt the big sack cleaner of positive press filtration back suction wind deashing, also can adopt other forms of sack cleaner, the format technology parameter of sack cleaner is according to the exhaust smoke level in the perlite production process, and exhaust gas temperature and deduster kind are determined.

Claims

1. smoke eliminator is reclaimed in a shaft kiln expanded perlite classification, mainly comprises one-level cyclone dust collectors, air blast, feed bin, material transport pipeline, bleeder valve and air-introduced machine; It is characterized in that: behind described air-introduced machine, be provided with a sack cleaner.

2. smoke eliminator is reclaimed in shaft kiln expanded perlite classification according to claim 1, and it is characterized in that: described sack cleaner adopts the big sack cleaner of positive press filtration back suction wind deashing.
