Abstract
The utility model discloses double base cloth reinforced layer fiber filter felt which comprises a polyether-ether-ketone (PEEK) fiber dust greeting layer, a first PEEK filament base cloth layer, a PEEK fiber layer and a second PEEK filament base cloth layer from top to bottom in sequence. The filter felt is mainly applied to the flue gas dust removal field with high dust concentration and high temperature high corrosion, using temperature reaches above 250 DEG C, intensity is high, acidproof anticorrosion ability is strong, and the filter felt maintains enough intensity in the using process. Tensile resistance strength of the heat resistant fiber filter felt in longitude and latitude direction exceeds 2500 N/ 5 * 20cm, filtration precision reaches to 99.999 %, operating resistance is around 800 Pa, ventilation quantity is 16 cubic meter/square meter * minute. The double base cloth reinforced layer fiber filter felt has obvious advantages on aspects of the filtration precision and equipment operating resistance.

Background technology
In the high temperature fume dust removal field, smoke components is complicated at present, and corrosivity is stronger, and require high service life, and filtrate in use various problems can occur.
Polyether-ether-ketone (PEEK) fiber was released the eighties in 20th century, it is a kind of novel high temperature heat-resistant plasticity special fibre, LOI value 35,334～343 ℃ of fusing points, 250 ℃ of long-term serviceability temperatures, coefficient of friction is low, has excellent anti-wear performance, fatigue resistance and creep-resistant property are excellent, are highly suitable for high dust concentration, the application of high temperature fume dust removal field.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of double-basis cloth enhancement Layer fiber filter felt is provided, and is implemented in dedusting in high dust concentration, the high flue gas that corrodes of high temperature.
The utility model is achieved through the following technical solutions, and the utility model comprises successively that from top to bottom polyetheretherketonefiber fiber meets knoisphere, the first polyether-ether-ketone long filament base cloth layer, polyetheretherketonefiber fiber layer and the second polyether-ether-ketone long filament base cloth layer.
Described polyetheretherketonefiber fiber meets knoisphere and the first polyether-ether-ketone long filament base cloth layer fixes by acupuncture, and polyetheretherketonefiber fiber layer and the second polyether-ether-ketone long filament base cloth layer fix by acupuncture.
The utility model has the following advantages compared to existing technology: this filter felt is mainly used in the flue gas ash removal field of high dust concentration, the high corrosion of high temperature, serviceability temperature reaches more than 250 ℃, intensity is higher, and the acid corrosion-resistant ability is strong, in use keeps enough intensity; This filter felt all surpass 2500N/5*20cm through broadwise tension brute force, its filtering accuracy reaches 99.999%, running resistance is about 800Pa, Air permenbility is 16m
3/ m
2Min.All has obvious advantage aspect filtering accuracy, the equipment running resistance.
