preparation example Construction

[0035] A preparation method of tourmaline functional medical waste incinerator special filter material, comprising the following steps:

[0036] Step 1: using fibers containing at least PTFE or PPS as raw materials, and obtaining nonwoven fabrics by needle punching;

[0037] Step 2: preparing nano tourmaline particles by chemical co-precipitation method;

[0038] Step 3: adding the nano tourmaline particles in step 2 to an organic surfactant solvent to prepare a magnetic fluid nano tourmaline solution;

[0039] Step 4: Dissolving and dispersing the ferrofluid nano-tourmaline solution, and adding TiO2 particles to prepare a solution with a certain binding effect;

[0040] Step 5: Using a dipping process, the emulsion is fully coated on the non-woven fabric in step 1 to obtain the required filter material.

[0041] As a preferred embodiment, in the first step, the nonwoven fabric is made from fibers containing at least PTFE or PPS through opening, mixing, carding, web laying and...

Embodiment 1

[0074] Opening: The non-woven fabric layer is made of 20% polyphenylene sulfide fiber PPS and 80% polytetrafluoroethylene fiber PTFE as raw materials. Woven felt. The polyphenylene sulfide fiber had a linear density of 1.5D and a fiber length of 60 mm, and the polytetrafluoroethylene fiber had a linear density of 1.0D and a fiber length of 51 mm. Due to the strong electrostatic effect of PTFE fiber, a non-ionic antistatic agent is added during the mixing process.

[0075] Carding: Due to the high density of PTFE fibers, poor strength of single fiber, and small curl, titanium alloy card clothing is used in the carding process, and the speed of the carding machine is reduced to 750r / min.

[0076] Laying net: small fiber cohesion force, small draft between the trolleys. The speed of the upper trolley is 33m / min, the speed of the laying trolley is 40m / min, and the speed of the lower trolley is 12m / min.

[0077] Acupuncture: 5 acupuncture machines are used, the last two are hete...

Embodiment 2

[0088] Opening: the non-woven fabric layer is made of 100% polytetrafluoroethylene fiber PTFE, which is mixed and opened, carded into a web, laid and needled five times to form a non-woven felt. The polytetrafluoroethylene fiber had a linear density of 1.0 and a fiber length of 51 mm. Due to the strong electrostatic effect of PTFE fiber, a non-ionic antistatic agent is added during the mixing process.

[0089] Carding: Due to the high density of PTFE fibers, poor single fiber strength and small curl, titanium alloy card clothing is used in the carding process, and the speed of the carding machine is reduced to 700r / min.

[0090] Laying net: small fiber cohesion force, small draft between the trolleys. The speed of the upper trolley is 30m / min, the speed of the laying trolley is 34m / min, and the speed of the lower trolley is 10m / min.

[0091] Acupuncture: 5 acupuncture machines are used, the last two are heterotopic pricking machines. The first acupuncture frequency and dept...

Abstract

The invention discloses a filtering material special for a medical waste incineration plant and a preparation method thereof, and belongs to the field of filtering materials. The preparation method comprises the following steps that fibers at least containing PTFE or PPS are adopted as raw materials, and non-woven fabric is obtained through needling forming; nano tourmaline particles are prepared through a chemical coprecipitation method; the nano tourmaline particles are added into an organic surface active agent solvent, and a magnetofluid nano tourmaline solution is prepared; the magnetofluid nano tourmaline solution is dissolved and dispersed, TiO2 particles are added, and a solution with a certain bonding effect is prepared, wherein magnetofluid nano tourmaline accounts for 15% to 25% of the total mass; immersion treatment is carried out, and the solution is smeared to the non-woven fabric to obtain the needed filtering material. The filtering material special for the medical waste incineration plant and the preparation method thereof have the advantages that emulsion layer coating fibers are formed on the non-woven fabric, treatment is carried out, chemical and physical filtering is achieved, the brand-new multifunctional air filtering material is formed, and the effects of chemical dust removal, bacterium resisting, disinfecting, low filtering resistance, high filtering efficiency and the like are achieved.

Description

technical field [0001] The invention relates to the field of filter materials, in particular to a special filter material for medical waste incineration plants and a preparation method thereof. Background technique [0002] At present, the filter material has the function of blocking dust and filtering dust particles, but it is not suitable for eliminating chemical gas corrosion. Antibacterial, poor removal of harmful substances. [0003] Waste-to-energy can effectively remove garbage, reduce pollution, and at the same time turn waste into wealth and create economic benefits. Therefore, it has achieved rapid development recently, but due to China's domestic market conditions such as unclassified and grading of garbage and limited incineration technology, the exhaust gas produced by it is very polluting. [0004] For garbage incinerators, the average growth rate of garbage in the world is 8.42%, while the growth rate of garbage in China has reached more than 10%. The world...
