Description

Pendant bounce-back bag type dust removal device

Technical Field

The utility model belongs to the technical field of the dust remover, concretely relates to dust remover of high-efficient lasting purification rate.

Background

Today, with the increasing awareness of people on atmospheric environment protection, the national environmental protection policy starts in 2017, the strict management is strengthened, however, the haze problem cannot be fundamentally solved, the air quality is good for less than two years, the haze is still serious in 2019, so that the result is shown? Because the existing dust removal technology and equipment cannot maintain the lasting purification rate, the purification efficiency is very high in the first two years, the inspection is qualified and reaches the standard, and then the dust removal efficiency is not as high as one year in one year, which is the fact that the existing dust removal technology cannot be changed!

Because the existing main dust removal modes have many defects, the pulse filter bag dust removal technology has the biggest defect that due to the instantaneous expansion of pulses and the friction between a hard framework and a filter bag, the filter bag is damaged by wire drawing, dust-containing gas can directly discharge to pollute the atmosphere, the filter bag has huge loss and short service life, and the dust removal operation cost is very high; the electric dust removal technology has the defects that the actual dust removal purification rate is lower than 99 percent, even if the electric dust removal is carried out at low temperature, the purification rate is 95 percent, the electric dust removal purification rate can be gradually reduced along with the increase of the service time, the power consumption is high, the purification rate of all dust is uneven, the occupied area is large, the assembly is easy to deform and damage, metal equipment can be gradually corroded, the maintenance cost is high, and the like, so that a new dust removal technology is needed for treating haze.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a pendant bounce-back bag collector to solve multiple shortcoming and the disadvantage that exists among the above-mentioned background art. The embodiment of the utility model provides a high-efficient low consumption's dust collector and dust removal method, its aim at can keep the lasting dust purification rate throughout the year, reduces the production condition of haze to and reduce the environmental protection running cost of enterprise.

On the first hand, the utility model provides a new dust removal method (technology), which is creative and practical, the pendant resilience dust removal mode is that a motor or a motor is used to pull or push the middle cross bar of a filter bag back and forth, the middle part of the whole filter bag is pulled to one direction, after being released, the dust is naturally rebounded and shaken off under the action of gravity or pulling force at the bottom of the filter bag, because the Tai Chi principle is utilized, the same air quantity is processed by using force, relative pulse back blowing and electric dust removal technology, a large amount of electric consumption can be saved, the same floor area is occupied, under the condition of not increasing the electric consumption, the dust removal pendant technology can lead the filter bag (barrel) to be infinitely increased, the processed air quantity is multiple times of pulse bag dust removal and electric dust removal, even can reach 10 times of the pulse bag dust removal and the electric dust removal, and the air resistance of natural filtration can also be reduced, the seam crossing speed of the dust-, the dust removing method is characterized in that micro dust can be attached to the plush surface of the filter bag, the pores of the filter bag cannot be quickly blocked due to overlarge wind pressure of blowing or induced wind, and due to the design of the pendant rebound dust remover, dust-containing gas enters the purifying chamber from the upper part after passing through the air inlet chamber, and can naturally move downwards along with the large resistance of the lower filtering area, and when the motor pulls the filter bag in a reciprocating manner and vibrates like a pull bow, and the vibration is generated by rebounding and rebounding vibration, the dust attached to the surface of the filter bag is naturally and gradually pushed downwards until being accumulated to the dust bin at the bottom.

The second aspect, the utility model provides an utilize dust collector of above-mentioned dust removal method design, which comprises a housin, the draught fan, a motor, block the pole, the filter bag, the gravity type body, the ash bucket etc, dirty gas gets into by one side entry of dust remover casing, through inlet chamber upper end entrance, reentrant clean room, filter the back through the filter bag in the clean room again, gas in the bag after the purification, again by the upper portion sack of filter bag, get into the clean room, then discharge in the export through the clean room, the dust that covers on the filter bag, horizontal pole at the filter bag middle part, under the motor pulling, form the action that the bow was kick-backed, the various shock waves that produce, the dust on the filter bag shakes off, fall into the ash bucket below the filter bag, the dust is transported away by other equipment again, accomplish whole flow.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the technical equipment can be in modularized butt joint, can be infinitely increased like building blocks, and is convenient to install.

2. A new dust removing method and dust removing apparatus, which has a lasting high purification rate; not only keeps the high purification rate of the cloth bag dust removal, but also utilizes the new dust removal method to solve the defects of the prior cloth bag dust removal, and can keep the lasting high purification rate throughout the year.

3. A new dust-removing method and dust-removing equipment features that the investment cost and running cost are low, and the noise and electric consumption of pulse compressor are not needed.

4. A new dust-removing method and dust-removing equipment features small floor area and large purifying air volume, and if the air volume is twice as large as the operating cost, the operating cost will be doubled. The dust removal device is not only suitable for dust removal of various manufacturing industries, but also suitable for low-temperature flue gas dust removal after butt joint of a flue gas energy-saving device, due to the popularization of an energy recovery technology, the temperature of dust exhaust gas is greatly reduced, and the pendant rebound dust removal technology is more suitable for dust removal of large-scale enterprises such as power plants, steel plants, cement plants and the like.
