Problems solved by technology

[0003] However, there are some problems with the current pulse injection technology. There is an obvious spatial uneven distribution of the dust removal effect on the filter cartridge, which is manifested by insufficient dust removal on the upper part of the filter cartridge, resulting in a large amount of dust remaining
In the prior art, the patent application number 201710377410.1 discloses a two-way cooperative pulse jet filter and dust removal system and its method. By controlling the start-up time difference between the electromagnetic pulse valve at the top and the electromagnetic pulse valve at the bottom, the collision of the injection airflow is realized. The maximum pressure cycle acts on all parts of the filter cartridge, but this technology has not yet considered the control of the pressure difference between the top and bottom nozzle outlets, and the two-way (collision) injection effect needs to be further improved

Embodiment 1

[0041] Taking the slide rails 5011 of the gradually opening circulation valve 5 and the gradually closing circulation valve 12 as an example, there are five pairs of locking protrusions 50111, and the corresponding baffle 501 has five stop positions so that the baffle 501 and the first valve housing Between 5091 and the second valve housing 5092, there are five gears of air flow passage area, that is, there are five gears of opening degree between the gradually opening circulation valve 5 and the gradually closing circulation valve 12 . The gear positions are defined by the opening degrees of the gradually opening circulation valve 5 and the gradually closing circulation valve 12, and the opening degrees are defined as first to fifth gears from small to large.

[0042] In this embodiment, it is set that the gradually opening circulation valve 5 is in the first gear, and the gradually closing circulation valve 12 is in the fifth gear.

Embodiment 2

[0058] When the part of the filter cartridge 14 needs continuous energy-concentrated colliding airflow to clean the dust, the position of the positioning rod 508 can be manually adjusted and the positioning screw 507 can be tightened so that the position of the positioning rod 508 is fixed. At this time, the sliding rod 503 is fixed by the positioning rod 508 , so that the baffle plate 501 cannot move, even if it is impacted by the pulse air flow, the gears of the gradually opening circulation valve 5 and the gradually closing circulation valve 12 will not change, and then keep the opening constant to maintain a stable outlet pressure.

Abstract

The invention discloses a clash pulse-jet filter cartridge ash removal system with automatic synergistic change of jet pressure. The clash pulse-jet filter cartridge ash removal system comprises a dust remover box body and a clash pulse-jet pipeline; a filter cartridge is sleeved in the dust remover box body, and the top of the filter cartridge is provided with a tubesheet to divide the interior of the box body into an air purification chamber and a filter chamber; the air purification chamber is provided with an air outlet, and the filter chamber is provided with an air inlet; the clash pulse-jet pipeline comprises an upper jetting pipe, a lower jetting pipe and an air bag, an air guiding pipe branch is further arranged between the upper jetting pipe and the air bag as well as between the lower jetting pipe and the air bag, and the air guiding pipe structure connects a gradually-opened circulating valve on the upper jetting pipe with the air bag, and connects a gradually-closed circulating valve on the lower jetting pipe with the air bag. According to the invention, through a plate baffle and a slide bar matched with the plate baffle, the opening degree of the valves is automatically and cyclically changed under the impact of pulse airflow, so that the outlet pressure of nozzles at the top and the bottom is controlled, the pulse airflow circularly acts on each part of the filter cartridge through collaborative collision jetting, the structure is simple, and more uniform dust removal of the filter cartridge can be realized.

Description

technical field [0001] The invention relates to the technical field of dust removal equipment, in particular to a colliding pulse spray filter cartridge dust cleaning system with automatic and coordinated change of spray pressure. Background technique [0002] As a device that can separate dust from dust-laden airflow, pulse jet dust collector plays an important role in the prevention and control of dust pollution. The pulse jet dust collector needs to regularly spray compressed air back to the filter cartridge for dust removal to ensure its stable operation. [0003] However, there are some problems in the current pulse injection technology, and there is an obvious spatial uneven distribution of the dust removal effect on the filter cartridge, which is manifested by insufficient dust removal on the upper part of the filter cartridge, resulting in a large amount of dust remaining. In the prior art, the patent application number 201710377410.1 discloses a two-way cooperative...
