In chemical, petroleum, metallurgical and other industries, high temperature dust-laden gases are often produced. Because different processes need or recover energy or reach environmental emission standards, the high-temperature dust-containing gas needs to be dedusted.
The high-temperature dust removing common equipment is provided with a high-temperature electric dust remover and a high-temperature bag type dust remover, wherein the high-temperature dust remover has the problems of unstable corona discharge, short service life of an electrode, high-temperature insulation and the like although the dust removing efficiency can reach about 95 percent; the bag type dust collector has unique advantages in the aspect of high-temperature dust collection: (1) dust removal performance; (2) the method has strong adaptability to working conditions, and the change of the smoke quantity and the dust concentration does not influence the outlet emission concentration, but only influences the ash removal frequency; (3) the structure is simple, and the operation and maintenance are convenient; (4) until the single dust removing equipment is damaged, the dust removing efficiency is increased along with the increase of the operation years, and the like. Therefore, the adoption of the high-temperature metal filter bag for filtering the flue gas is one of effective modes for realizing high-temperature dust removal, and is also one of promising technologies in the industry of purifying the particulate matters.
The existing ash removing modes of the metal filter bag mainly comprise pulse blowing ash removing and mechanical vibration ash removing.
The pulse blowing ash removal uses compressed air with the pressure of 3-6 kg as power, and compressed air flow is instantly released by a pulse blowing mechanism to generate shock waves, so that the filter bag vibrates, and a dust layer deposited on the filter bag falls off. Because the metal filter bag has better rigidity, the bag does not deform during blowing, and therefore, larger ash removal pressure is needed during ash removal.
Mechanical vibration ash removal utilizes mechanical vibration or shaking of a frame suspending the filter bag to enable the filter bag to vibrate and shake off dust. The mechanical structure of the vibration ash removing mode is simple, the operation is reliable, but the ash removing effect is weaker.

Detailed Description
The technical scheme of the utility model is further specifically described by the following specific embodiments with reference to the accompanying drawings:
examples: as shown in figure 1, the metal filter bag consists of a filter membrane 1, a fixed support 2, a bag bottom sealing plate 3, a vibrating anvil 4 and a vibrating rod 5. The function of the metal filter bag is to filter dust in the flue gas, so as to realize the purpose of flue gas purification.
The filter membrane 1 is based on nano-scale and micro-scale metal powder, takes metal, metal oxide and alloy as membrane materials, adopts continuous gradient asymmetric structural design, and consists of a micro-nano membrane layer, a transition layer, a framework layer and an air permeable layer. The filter is mainly used for filtering dust in the flue gas, when the flue gas passes through the filter membrane, the dust is blocked on the surface of the filter membrane, and clean gas passes through the filter membrane.
The fixed support 2 is composed of a neck ring 1.1, a support rod 1.2 and a support disc 1.3 as shown in figure 2. For fixing and supporting the entire filter bag. The necked ring 1.1 is connected with the filter membrane and welded with the support rod, as shown in fig. 3, and the necked ring is firmly pressed on the pattern plate (a sealing ring is placed between the necked ring and the pattern plate) through the bolts and the limiting blocks, so that the whole metal filter bag is fixed on the pattern plate. Wherein, the two ends of the supporting rod 1.2 are respectively welded with the necked circular ring 1.1 and the supporting disc 1.3 for supporting the supporting disc 1.3. Wherein the side of the supporting disc 1.3 is welded with the supporting rod 1.2, and the supporting disc is welded with the rapping rod 5 for supporting the rapping rod 5.
A bottom sealing plate 3 is used for sealing the bottom of the filter bag. As shown in fig. 4, the type is a neckdisk, the neck is connected with the filter bag, and the vibrating anvil 4 and the vibrating rod 5 are connected with the upper and lower surfaces of the neckdisk.
