燃煤熱風爐主要是以燒煤為主,煤塊是有C/H/O/S等化學元素組成的,如果在燃煤熱風爐不完全燃燒的狀態下,它會產生大量的有毒氣體,危害人的身體健康,其實浙西額問題我們早就有了相應的防護措施,那么其燃燒后多會產生哪些有害氣體,都有哪些具體危害呢? 分享延長熱風爐使用壽命的方法有哪些 熱風爐使用過程中經常會遇到一些這樣那樣的問題,使用熱風爐的朋友們除了仔細閱讀使用說明書外,還需要注意以下問題以便延長熱風爐使用壽命,保持熱風爐優良的性能。inordertoprolongtheservicelifeofhotblaststovean…

燃煤主要是以燒煤為主,煤塊是有C/H/O/S等化學元素組成的,如果在燃煤不完全燃燒的狀態下,它會產生大量的有毒氣體,危害人的身體健康,其實浙西額問題我們早就有了相應的防護措施,那么其燃燒后多會產生哪些有害氣體,都有哪些具體危害呢?對癥下藥,又應如何預防?小編下面簡要介紹如下:
Coal-fired hot-blast stove is mainly coal-fired, coal block is composed of C/H/O/S and other chemical elements. If the coal-fired hot-blast stove is not fully burned, it will produce a large number of toxic gases, endangering human health. In fact, we already have corresponding protective measures for the problem of Western Zhejiang, then it will be produced after combustion. What are the harmful gases and their specific hazards? How to prevent the symptoms? The following is a brief introduction to the minor edition: 燃煤燃燒后主要大氣污染物就是硫氧化合物。煤炭在燃燒時產生的穩定產物是SO2與SO3,但SO3的含量甚微。以SO2為主,二氧化硫是一種無色不可燃的有毒氣體,具有強烈的辛辣、刺激性氣味。主要損害上呼吸道,因為它易溶于水形成亞硫酸刺激眼和鼻粘膜,具有腐蝕性;二氧化硫在組織液中的溶解度很高,所以吸入空氣中的二氧化硫很快會溶解消失在上呼吸道,很少進入深部氣道,因此只有深度呼吸或二氧化硫吸附在塵粒表面上時才有可能進入肺部,就會對人體健康產生明顯危害,鼻腔和呼吸道粘膜都會出現刺激感;能夠引起支氣管收縮與聲帶痙攣,進而還會發生鼻腔出血、呼吸困難等,還會誘發支氣管炎、肺水腫、肺硬化等疾病,甚至死亡。此外,SO2還可增強致癌物苯并芘的致癌作用。
Sulfur oxides are the main air pollutants in coal-fired hot blast stoves after combustion. The stable products of coal combustion are SO2 and SO3, but the content of SO3 is very small. Sulfur dioxide is a colorless, non-flammable, toxic gas with a strong pungent and irritating odor. It mainly damages the upper respiratory tract, because it is easy to dissolve in water to form sulfite to stimulate the eyes and nasal mucosa, which is corrosive. The solubility of sulfur dioxide in tissue fluid is very high, so sulfur dioxide in inhaled air will dissolve quickly and disappear in the upper respiratory tract, rarely into the deep airway, so only deep breathing or sulfur dioxide adsorption. On the surface of dust particles, it is possible to enter the lungs, which will cause obvious harm to human health, irritation of nasal cavity and respiratory mucosa, bronchoconstriction and vocal cord spasm, and then nasal bleeding, dyspnea, bronchitis, pulmonary edema, pulmonary sclerosis and other diseases, or even. Death. In addition, SO2 can enhance the carcinogenicity of benzopyrene, a carcinogen.

長期接觸二氧化硫的人一方面刺激上呼吸道引起支氣管平滑肌反射性收縮,呼吸阻力增加,呼吸功能衰落,另一方面刺激和損失粘膜,使粘膜分泌增多變稠,纖毛運動受阻,免疫功能減弱,導致呼吸道抵抗力下降,誘發不同程度的炎癥,如慢性鼻咽炎、慢性支氣管炎,支氣管哮喘和肺氣腫等。此外長期接觸二氧化硫對大腦皮質機能產生不良影響,使大腦勞動能力下降,不利于兒童智力發育。值得注意的是SO2、SO3與水氣、煙塵等結合形成硫酸煙霧及硫酸鹽后,造成的生態環境污染和危害遠比單一的SO2大得多,其毒性作用可增大34倍,若硫酸霧氣溶膠的微粒為重金屬粒子時,其刺激作用比SO2的單獨刺激作用增強10倍,因為硫酸霧氣溶膠微粒能夠侵入肺的深部組織。
Long-term exposure to sulfur dioxide on the one hand stimulates the upper respiratory tract to cause bronchial smooth muscle reflex contraction, respiratory resistance increases, respiratory function decline, on the other hand stimulates and loses mucosa, which makes mucosal secretion become more and more thick, cilia movement is blocked, immune function is weakened, resulting in respiratory tract resistance decline, induce different processes. Degree of inflammation, such as chronic nasopharyngitis, chronic bronchitis, bronchial asthma and emphysema. In addition, long-term exposure to sulphur dioxide has a negative impact on the function of cerebral cortex, which reduces the working ability of the brain and is not conducive to children's intellectual development. It is worth noting that the combination of SO2 and SO3 with water, smoke and dust to form sulfuric acid smoke and sulfate causes much more environmental pollution and harm than that of single SO2. Its toxicity can be increased by 34 times. If the particles of sulfuric acid aerosol are heavy metal particles, its stimulation effect is enhanced by 10 times than that of SO2 alone. Because sulfuric acid aerosol particles can penetrate deep lung tissue.
