Problems solved by technology

This treatment method is less harmful to human life, but its cost is very expensive, and the half-life of radioactive substances is generally more than 50-100 years, which will damage the environment for a long time
In particular, in the nuclear industry environment, each worker enters and exits the workplace many times a day, consuming many sets of protective clothing every day, resulting in a huge amount of waste disposal, which not only costs a huge amount of money, but also causes increasing damage to the global environment. Long-term hidden danger

Embodiment 1

[0025] Embodiment 1, nuclear industry special lab coat and waste reprocessing thereof

[0026] Protective clothing is made of 60 g / m2 water-soluble polyvinyl alcohol spunlace nonwoven fabric, water-soluble polyvinyl alcohol sewing thread, water-soluble tape, zipper, etc. The protective clothing fabric can be completely dissolved in water.

[0027] After being used and discarded, put it into a storage bag with a thickness of 0.04mm and a size of 0.8mX1m (such as figure 1 ), heat-sealing lines 1 are formed on both sides of the storage bag, and the drawstring 6 is tightened to seal.

[0028] The discarded protective clothing, together with the storage bag, is put into the stainless steel melting furnace 2 (such as figure 2 ), dissolved in 95°C water while stirring, and after 1.5 hours, the aqueous solution was sent to the storage tank 4 by the delivery pump 3 for temporary storage, except for the insoluble matter such as Velcro. A very small amount of insoluble matter is bloc...

Embodiment 2

[0033] Embodiment 2, nuclear industry special work clothes and waste reprocessing thereof

[0034] Using 60 g / m2 water-soluble polyvinyl alcohol spunlace nonwoven fabric and 0.025mm water-soluble polyvinyl alcohol film, the two layers are composited together by ultrasonic waves to form a protective clothing fabric, and water-soluble polyvinyl alcohol sewing thread, Water-soluble tapes, zippers, water-soluble labels, etc., made into protective clothing. The protective clothing fabric can be completely dissolved in water.

[0035] After use and discarding, put it into a storage bag with a thickness of 0.04mm and a size of 1mX1m (such as figure 1 ), tighten the drawstring 6 to seal.

[0036] The discarded protective clothing, together with the storage bag, is put into a stainless steel melting furnace and dissolved in 95°C water while stirring. After 1.5 hours, the aqueous solution is sent to the storage tank by the delivery pump for temporary storage except for the insoluble mat...

Embodiment 3

[0041] Embodiment 3, special electric welding protective clothing for nuclear industry and its waste reprocessing

[0042] Using 130 g / m2 water-soluble polyvinyl alcohol spunlace nonwoven fabric, through two processes of flame-retardant impregnation and coating, a water-soluble biodegradable high-temperature heat-resistant and heat-resistant protective clothing fabric with a grammage of 300 g / m2 . The fabric, water-soluble polyvinyl alcohol sewing thread, water-soluble tape, zipper, water-soluble label, etc. are made into special protective clothing for maintenance and electric welding. The protective clothing fabric is 94% soluble in water.

[0043] After use and disposal, put it into a storage bag with a thickness of 0.04mm and a size of 1mX1m, and tighten the drawstring to seal it.

[0044] The discarded protective clothing, together with the storage bag, is put into a stainless steel melting furnace and dissolved in 95°C water while stirring. After 1.5 hours, the aqueous...

Abstract

The invention discloses a disposable protective garment for a nuclear industry and a processing method after the disposable protective garment is used. In the prior art, a traditional protective garment for the nuclear industry is large in waste processing amount, a large amount of money is wasted, and increasingly expansive long-term hidden danger to earthly environment is caused. The disposable protective garment is made of water solubility polyvinyl alcohol cloth or composite shell fabrics of the water solubility polyvinyl alcohol cloth and water solubility polyvinyl alcohol films. After the disposable protective garment is used at one time, the waste processing method comprises the following steps that the protective garment is dissolved in hot water, a minute quantity of radioactive ash stained on the protective garment is acquired through filtering collection, and eventually deeply-buried processing is conducted. Water solution filter liquor can be directly discharged to soil, microorganisms in the soil fully degrade the water solution filter liquor, and no pollutant residual is left. Compared with the traditional protective garment, processing cost of waste is greatly saved, and ecological environment is protected.

Description

technical field [0001] The invention relates to the field of protective clothing, in particular to a special disposable protective clothing for the nuclear industry made of water-soluble biodegradable materials and a treatment method after use. Background technique [0002] The daily operation and maintenance of a nuclear power plant is inseparable from various professional staff. When they work in the facility, they may be contaminated by radioactive dust. The use of protective products that are reused many times is not only expensive to decontaminate, but also prone to contamination due to decontamination. The risk of radioactive dust contamination is brought about by unclean elimination. The high-risk security features of the nuclear industry determine that the environmental internal protective equipment has a disposable feature. [0003] As disposable work clothes that may be contaminated with radioactive dust, it is also very difficult to dispose of them as waste aft...
