[0003] But the main disadvantage is that the dust removal efficiency is greatly affected by the physical and chemical characteristics of flue gas and dust, and the dust removal effect is not ideal for high specific resistance dust, fine and ultrafine dust, etc.

Embodiment 1

[0015] The dust-laden gas enters the dust collector from the air inlet, first hits the inclined plate and baffle in the middle of the air inlet and outlet, the airflow turns to flow into the ash hopper, and at the same time, the airflow speed slows down. Due to inertia, the coarse particles in the gas flow directly into the ash hopper. . It plays a role of pre-collection of dust. The airflow entering the ash hopper is then folded upwards and passes through the filter bag with a metal skeleton inside. The dust is trapped on the outer surface of the filter bag. The purified gas enters the upper clean room of the filter bag chamber and is collected to the outlet. Air outlet,

[0016] In the process of purifying dusty gas through the filter bag, more and more dust accumulates on the filter bag with the increase of time, which increases the resistance of the filter bag, resulting in a gradual decrease in the air volume. For normal work, the resistance must be controlled at a certain l...

Abstract

The invention discloses a dust bag type dust removal process under the disordered and uneven state. A fold filter bag is designed to replace a traditional round or oval cloth bag, a specialized cage bone is used cooperatively, and the filter area of the filter bag is increased by more than 60%; meanwhile, a mass-flow low-frequency pulse valve blast cleaning technology is adopted, the dust-removal pressure differential is increased to 1.2kPa, the pulse frequency is reduced to 30 seconds/time, dust-removal frequency is greatly lowered, service life of the filter bag can be prolonged, times for operating maintenance are reduced, and dust-removal efficiency is improved obviously; therefore, through application of the Internet of Things technology, systems in measurement of dust concentration, start-stop of dust removal equipment, monitoring and inspecting and the like can be automatically controlled, and labor cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of dust removal, in particular to a dust bag dust removal process in a disordered and uneven state. technical background [0002] At present, the mainstream domestic dust removal technologies include electrostatic dust removal, bag dust removal and electric bag compound dust removal. Since the electrostatic precipitator (ESP) was used in industry, it has developed into a recognized high-efficiency dust removal device with an efficiency of over 99%. The advantages of electrostatic precipitator are that the body pressure loss is small, the single machine handles a large amount of flue gas, high temperature resistance, and low maintenance costs. [0003] But the main disadvantage is that the dust removal efficiency is greatly affected by the physical and chemical characteristics of the flue gas and dust, and the dust removal effect is not ideal for high specific resistance dust, fine and ultrafine dust. [0004] Compa...
