Problems solved by technology

However, in some high-temperature production industries, such as the titanium dioxide industry, the temperature of the flue gas entering the dust collector is as high as 400 ° C, and the conventional filter bag is easily damaged at high temperature, and the filter bag cannot be used any longer.

Embodiment

[0040] An ultra-high temperature resistant bag filter, such as figure 1 , including the dust collector body 1, the four corners of the lower end of the dust collector body 1 are provided with supporting columns 61 extending downward, and the supporting columns 61 support the dust collector body 1.

[0041] Such as figure 1 When the dust collector body 1 filters the exhaust gas with a high temperature, the dust collector body 1 will expand and deform when heated, resulting in a decrease in the safety of the dust collector body 1 . The support column 62 is connected to the bottom of the support column 61 through the anti-expansion device. When the support column 61 is heated and expanded by the anti-expansion device, it is not easy to stagger with the support column 62 due to expansion, causing the dust collector body 1 to tilt or even collapse. Case.

[0042] Such as figure 2 , the anti-expansion device comprises a transverse first anti-expansion plate 63, the first anti-expa...

Abstract

The invention relates to dust removal equipment, and discloses an ultra-high temperature resistant bag type dust remover. The bag type dust remover comprises a dust remover body; an inner cavity of the dust remover body is divided into a clean air chamber and an inertia settling chamber through a partition plate; a plurality of clean air ports are formed in the partition plate; filter bag bodies positioned in the inertia settling chamber are respectively arranged in the clean air ports; and each filter bag body comprises a fixed framework and a heat-resistant felt which is arranged around theouter side of the fixed framework, wherein the filter bag body is in a cylindrical structure, and the heat-resistant felt is in a reticular structure made of a metal material. The heat-resistant feltmade of the metal material has high-temperature resistance, and thus can adapt to a working environment at a high temperature, so that the service life of the filter bag bodies is prolonged. The fixedframeworks form skeletons of the filter bag bodies and support the heat-resistant felts, so that structural strength of the heat-resistant felts is ensured, and the heat-resistant felts are preventedfrom deforming, and therefore, the service life of the heat-resistant felts is prolonged.

Description

technical field [0001] The invention relates to dust removal equipment, in particular to an ultra-high temperature resistant bag type dust collector. Background technique [0002] Pulse bag filter is a dry dust removal device, also known as filter dust collector. It is a dust removal device that uses a bag filter element made of fiber woven fabric to capture solid particles in dusty gas. It has high dust removal efficiency, With the advantages of flexible use and stable operation, it is widely used in dust purification in various industrial fields such as mines, cement, and building materials. [0003] The dust filter bag is an important part of the bag filter. The purified gas enters the box through the filter bag and is discharged from the air outlet. The commonly used filter bag materials are PE, PP, PTFE, PMIA, NMO, etc. However, in some high-temperature production industries, such as the titanium dioxide industry, the temperature of the flue gas entering the dust colle...
