Description
Technical Field
The invention relates to a remains deodorizing disinfectant, belonging to the technical field of human remains preservation.
Background
After death, remains are putrefactive, and, in the process of putrefaction, odor is emitted. The gases generated by putrefaction of remains are mainly sulfur dioxide (SO)2) Carbon dioxide (CO)2) Hydrogen sulfide (H)2S), ammonia (NH)3) Methane (CH)4) Among these gases, sulfur dioxide (SO)2) Hydrogen sulfide (H)2S), ammonia (NH)3) Can cause odor. These odor causing gases not only harm the funeral service personnel's health, but also are not conducive to soothing the departed family.
At present, no special disinfectant for body deodorization is available in the funeral industry, and 84 disinfectant or Jiaomba disinfectant is generally adopted, the two disinfectants mainly use hypochlorous acid for disinfection and sterilization, the effect of eliminating body odor in the body is not great, and gas generated by body putrefaction mainly contains sulfur dioxide (SO)2) Carbon dioxide (CO)2) Hydrogen sulfide (H)2S), ammonia (NH)3) Methane (CH)4) Among these gases, sulfur dioxide (SO) is the dominant odor causing gas2) Hydrogen sulfide (H)2S), ammonia (NH)3). Hypochlorous acid used for sterilization reacts with these odor-causing gases and further generates other toxic and harmful gases, for example, HClO + SO2+H2O＝HCl+H2SO4The generated HCl has strong pungent smell and toxicity; 2HClO + H2S＝Cl2Gas +2H2O + S precipitation, chlorine gas has strong pungent smell and is yellow green toxic gas; 3NH3+HClO＝＝N2H4+NH4Cl+H2O，N2H4A colorless oily liquid having corrosiveness and strong reducibility, which is extremely toxic and unstable, and has a pungent odor similar to ammonia. Therefore, the disinfectant containing hypochlorous acid is used for disinfecting the putrefactive remains, so that the odor cannot be eliminated, and harmful substances are generated, and the environment and the body health of funeral workers are not improved.
In view of the fact that the disinfectant cannot achieve the aim of deodorization, at present, a deodorizing liquid is often prepared separately in funeral and interment places, the used deodorant comprises peroxyacetic acid, potassium permanganate and the like, and the peroxyacetic acid is used as the deodorant and can only be prepared at present, because the peroxyacetic acid is formed by mixing A, B two components together, A, B two components are unstable together, proper water is required to be added during preparation, and the proportion of the water is not well controlled; potassium permanganate is also more used in the prior art, and the two chemical reagents are easily explosive dangerous goods, are not beneficial to the storage of the medicines by each pair of units, and are inconvenient to use.
hydrogen peroxide is a strong oxidant, has disinfecting, antiseptic and cleaning effects, and is often used as a disinfectant and antiseptic agent. For example, CN101954105A discloses a method for removing odor of feces and urine of livestock and poultry by oxidation, which utilizes the strong oxidizing property of ferrate and the strong oxidizing property of hydroxyl radical generated by hydrogen peroxide under the catalysis of ferrate reduction product to completely and completely remove various odor components by oxidation. For another example, CN102084869A discloses a compound hydrogen peroxide disinfectant, which utilizes the characteristic that hydrogen peroxide can generate free radicals to exert a bactericidal effect.
However, the process of body deodorisation has its own specificities, including:
(1) In the process of deodorizing the dead body, the color which is not beneficial to the make-up of the dead body can not be generated, and if the method refers to the oxidation removal of the livestock and poultry manure disclosed in CN101954105AThe method for deodorizing and disinfecting the remains by utilizing the strong oxidizing property of ferrate can generate polysulfide, and dark green ferric trisulfide (Fe) can be formed on the surfaces of the remains2S3) The original color of the remains is changed, the remains are not beneficial to make-up, ferrate FeO4 2-absorption of hydrogen sulfide H2Chemical reactions that may occur after S gas:
2NaOH+H2S＝NaS+2H2O ①
2FeO4 2-+3S2-+8H2O＝2Fe(OH)3↓+3S↓++10OH- ②
2FeO4 2-+6S2-+8H2O＝Fe2S3↓+3S↓+16OH- ③
S+ns＝SN+1 2- ④
8FcO4 2-+3S2-+20H2O＝8Fe(OH)3↓+3SO4 2-+16OH- ⑤
8FeO4 2-+15S2-+20H2O＝4Fe2S3↓+3SO4 2-+40OH- ⑥
(2) Measuring sulfur dioxide (SO) in the sealed space during the process of deodorizing putrefactive remains2) At a concentration of about 1.2-8.58mg/m3Hydrogen sulfide (H)2S) concentration of about 90-130mg/m3Ammonia (NH)3) Has a concentration of about 150-210mg/m3(ii) a By the chemical equation SO2+H2O2＝H2SO4、H2O2+H2S＝2H2O+S↓、2NH3+3H2O2＝N2↑+6H2O, it can be calculated that 540.64-834.33 is consumed in the process of deodorizing putrefactive remains2mg/m320000mg of disinfectant containing 3% of hydrogen peroxide is required to be sprayed per cubic meter in the process of sterilizing the remains, 600mg of hydrogen peroxide is required per cubic meter, and 1m of hydrogen peroxide is required to be sprayed per cubic meter in the process of sterilizing the remains3The putrefactive odor emitted from putrefactive remains in the space is deodorized by 1140.64-1434.33 mgHydrogen oxide, and when 20000mg of the disinfection and deodorization solution is sprayed per cubic meter for achieving the purpose of disinfection and deodorization at the same time, the concentration of hydrogen peroxide in the disinfection and deodorization solution should be 5.732% -7.17%.
(3) CN102084869A discloses a compound hydrogen peroxide disinfectant, wherein the concentration of hydrogen peroxide is 8.5% -12.5%, the concentration is relatively high, if the content of hydrogen peroxide is too high, the production cost can be increased, and if the concentration of hydrogen peroxide exceeds 8%, the compound hydrogen peroxide disinfectant belongs to an easily explosive dangerous article and is not favorable for purchase and use.
