Problems solved by technology

In the port bulk grain unloading operation system, the most commonly used domestic dust collector is the MC pulse bag filter, which has played an important role in production, but there are still many problems, such as the small adaptability to dust concentration, explosion-proof , Moisture-proof performance is poor, there are many wearing parts, and it is necessary to supply compressed air with an air compressor station. , therefore, there is an urgent need for a new dust removal device to solve the above technical problems

Embodiment 1

[0011] Example 1: see figure 1 , a new environmental protection dust removal device, the new environmental protection dust removal device includes an upper box, a middle box 4, a filter assembly, a dust removal system, an ash hopper part, and an ash discharge system, and the filter cloth bag is arranged in the middle box. The lower part of the box is equipped with an ash discharge system, wherein the upper box includes a clean air chamber, an inspection cover, and a clean air outlet; the middle box includes a perforated plate, an air inlet, and an inspection door; Observation port; the filter assembly includes a filter bag 5, a bag frame, and a bayonet; the dust removal system includes a blowing pipe 3, a high-pressure reverse blower 8, and a reverse blowing rotary mechanism 2; the ash discharge system includes a dust discharge lock 7, a rotary Dust scraping device 6; the auxiliary equipment includes guardrails and ladders 1, etc., the dust-laden airflow enters the middle bo...

Embodiment 2

[0012] Example 2: see figure 1 , as an improvement of the present invention, the ash hopper box adopts a flat-bottomed ash hopper structure. The ash discharge system consists of a scraper mechanism and an ash discharge locker. The dust falling into the ash hopper is forcibly scraped to the ash unloading port by the ash scraper, and then discharged through the ash unloader, which destroys the condition of the dust arching, not only prevents the dust from forming arches, but also reduces the efficiency of the whole machine. height, so that the dust can be smoothly discharged from the dust collector.

Embodiment 3

[0013] Example 3: As an improvement of the present invention, the dust removal system adopts differential pressure control. When the resistance of the filter bag reaches the set value of 1200Pa, the dust removal system starts to clean the dust. When the value is 800Pa, the cleaning system stops working.

[0014] The working principle is as follows: In the system design, reverse air flow and back blowing are adopted. The high-pressure dust-cleaning airflow generated by the high-pressure fan passes through the filter cloth in the opposite direction to the filter airflow, so that the dust on the surface falls off and falls into the ash hopper. This dust cleaning method distributes the airflow evenly on the entire filter bag, the airflow does not contain water, and the wear rate of the filter bag is low, which can prolong the life of the filter bag and is not affected by the temperament. It does not need to provide compressed air and can independently form a dust removal syst...

Abstract

The invention discloses a novel environmental-protection dust removal device. The novel environmental-protection dust removal device is characterized by comprising an upper box body, a middle box body (4), a filter assembly, a dust cleaning system, a dust hopper assembly and a dust discharging system, wherein a filter cloth bag is arranged in the middle box body, the lower portion of the middle box body is provided with the dust discharging system, and the upper box body comprises a clear air chamber, an access cover and a clean air outlet; the middle box body comprises a multi-hole plate, an air inlet and an access door, and the dust hopper assembly comprises a dust hopper box body and an observation window; the filter assembly comprises the filter cloth bag (5), a cloth bag frame and a bayonet, and the dust cleaning system comprises a spray blowing pipe (3), a high-pressure reverse blowing fan (8) and a reverse blowing rotating mechanism (2); airflow with dust enters the middle box body (4) in a tangential mode through an air intake, part of rough and weight dust and part of coagulation dust falls to the bottom of the dust hopper along the cylinder wall of the box body, when part of fine dust drifts to the filter cloth bag (5) along with the airflow, the fine dust is captured and filter, and clean air passes through filter cloth to enter the upper box body and is discharged out from the clean air outlet.

Description

technical field [0001] The invention relates to the field of dust collectors, in particular to a novel environment-friendly dust removal device. Background technique [0002] In the process of bulk grain unloading and transportation, a large amount of dust will be released in the atmosphere, causing environmental pollution and endangering human health. When the dusty air is dry and the dust concentration is high, the risk of dust explosion is also increased, threatening Safety of persons and equipment. The method of ventilation and dust removal is used to collect and purify the dusty gas, which can effectively protect the environment and reduce the probability of dust explosion. The new environmental protection dust removal device is the most commonly used equipment for ventilation and dust removal. It mainly relies on the mechanism of filtration to separate dust from dusty gas, and has the characteristics of high efficiency and stable operation. In recent years, bag type ...
