Problems solved by technology

The steel bag cage has poor corrosion resistance, heavy weight, high production cost, and complicated anti-corrosion treatment process, which will greatly increase the cost
Especially in the application background of wet desulfurization at the present stage, the flue gas temperature is low, and the acid liquid formed by condensed water severely corrodes the dust removal framework, which shortens the service life of the steel bag cage used to support the dust removal bag due to corrosion and wear, and also causes Damaged dust bag

Embodiment 1

[0046]Typical embodiment one: (long-term use temperature below 260°C)

[0047] Material composition (by weight ratio):

[0048] Silicone resin

35

glass fiber

65

[0049] Preparation:

[0050] 1. Using the winding molding process, the glass fiber soaked in resin is wound on the mold according to certain process parameters to form a net

[0051] bag cage structure.

[0052] 2. Put it in an oven at 200℃~230℃ for 4-6 hours. Put the wrapped mold into an oven for thermal curing or normal temperature curing.

[0053] 3. After curing, remove the mold and trim the corners of the cage.

Embodiment 2

[0054] Typical embodiment two: (The long-term use temperature is below 220°C)

[0055] Material composition (by weight ratio):

[0056] Novolac Epoxy Vinyl Resin

[0057] Preparation:

[0058] 1. Stir the resin, flame retardant, filler and curing agent evenly first.

[0059] 2. After molding, heat to 160°C for curing, demoulding and trimming.

[0060] In order to further improve the verticality of the bag cage and the production efficiency of the bag cage, the bag cap of the bag cage of the present invention is integrally wound with the cage body structure. In order to meet the lateral and longitudinal strength requirements of the bag cage, the winding angle of the ribs and cross ribs on the mold can be adjusted, and the winding angle can be changed from 0° to 90° (the rib 1 and the cross rib 2 cannot be 0° or 90°). In order to further improve the overall compressive strength of th...

Abstract

The invention provides a resin matrix composite dust bag cage. The dust bag cage adopts a resin matrix composite, and solves the problem that the dust bag cage made of the traditional material is easily corroded during surface treatment. The dust bag cage takes a continuous fiber and matrix resin as raw materials and adopts a winding forming technology; the cage in a lattice structure is formed on a mold; and the strength, the temperature resistance and the corrosion resistance of the bag cage can be adjusted according to a use requirement.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a resin-based composite material dust removal bag cage. Background technique [0002] The dust removal bag cage is also called the dust removal frame, also known as the dust removal frame, which is usually formed by one-time welding with special equipment. The skeleton is the rib of the dust filter bag, and the quality of the bag cage directly affects the working condition and service life of the filter bag. The dust removal bag cages currently used in the market are mainly ordinary iron cages, stainless steel cages and anti-corrosion treated steel bag cages. There is no high temperature and corrosion resistant composite material bag cages on the market yet. The steel bag cage has poor corrosion resistance, heavy weight, high production cost, and complicated anti-corrosion treatment process, which will greatly increase the cost. Especially in the appl...
