XMC pulse bag filter

1、 Overview
The XMC pulse bag filter is a new type of dust collector developed by our company by introducing high-efficiency dust collectors from Germany with the technological level of the 1990s and combining them with Chinese characteristics. This dust collector adopts the technology of high-pressure (0.5~0.4MPa) high flow pulse valve to blow and clean the dust filter bags one by one. Capable of collecting over 99.9% of dust from a large amount of ultrafine dust (particles of £ 5 μ m, with a content of over 70%) and high concentration (1300g/m3n) gases. At the end of 1997, the dust collector passed provincial appraisal and was found to have a leading domestic level, with its main technology being the first of its kind in China. At present, under the new national environmental protection standards, it is widely used not only for dust control in cement plants, but also in the field of deep processing of non-metallic mineral fines. It also has good application prospects in industries such as power, chemical, metallurgy, and steel.
2、 Construction and working principle of XMC pulse bag filter
1. Structure of Pulse Spray Bag Dust Collector
The device mainly consists of the following parts:
(1) Box body: including bag chamber, pre dust collection chamber, clean air chamber, porous plate, filter bag, and filter bag skeleton. The box is designed to withstand a pressure of 9000Pa.
(2) Spray system: including main air pipe, spray pipe, flushing valve, and control instrument.
(3) There are two forms of ash hopper and ash discharge part: one is directly connected to the ash discharge valve, and the other is connected to the ash discharge through a conveying device.
2. The dusty gas enters the expanded ash hopper of the dust collector for pre dust collection, and is evenly distributed between each filter bag through the guide plate. The dust is retained on the surface of the filter bag. In order to ensure that the equipment resistance does not exceed 1200Pa, high-pressure gas is sprayed through the electromagnetic pulse valve, causing compressed air (0.5-0.7MPa) in the air bag to be sprayed out through the nozzle holes (called primary air) and induced by the Venturi tube to enter the filter bag several times the primary air (called secondary air). The filter bag expands rapidly in an instant, and the dust is shaken off with the reverse action of the airflow, achieving the purpose of dust cleaning. Using a microcomputer automatic control device, adjust the cleaning cycle and pulse spraying time according to the dust concentration, so that the dust collector operates within a certain resistance range.
3、 Selection of XMC pulse bag filter
1. Model Description
This single machine has nine specifications: 60-2, 60-3, 60-4, 60-5, 60-6, 70-5, 70-6, 70-7, and 70-8. 2. Selection parameters and selection principles
(1) The main technical parameters for selecting a dust collector are air volume, gas temperature, dust concentration, and humidity. According to the maximum values of air volume, gas temperature, and dust concentration in the process design, based on the principle of slightly lower values than those in the technical performance table, the corresponding dust collector model is the required dust collector model. The filter material used is determined based on the inlet concentration, gas temperature, and moisture content.
(2) The gas consumption in the table refers to the situation when the factory supplies gas centrally. If an air compressor is used separately, the gas consumption in the table should be increased by 1.5 times.
(3) The air consumption listed in the compressed air consumption column is the maximum air consumption of the equipment model.
3. The appearance and foundation of the equipment are shown in the attached diagram. Our company can also design a dust collector with a shape that meets the user's requirements based on the site conditions.
