山东省东营粉尘场所防火防爆電氣檢測管理过程中常见的问题有哪些？

2021-5-8 11:17:26

随着现代工业的发展，粉末技术得到了广泛应用，但是，许多粉体加工企业对粉体相关危害的认识不够深刻。部分企业在粉体的生产、储存、运输和应用过程中，安全管理比较混乱，缺乏必要的防火防爆设施。近年粉尘爆炸的事故频繁发生，而且粉尘爆炸具有很强的破坏力，往往造成较大的人员伤亡和损失，因此粉尘爆炸已经成为工业安全不可忽视的重要问题。　

企業粉塵防爆管理過程中存在的問題

目前，粉塵防爆存在的主要問題有以下幾點：

1、企業對粉塵危險性認識不足

　　部分企業對粉塵爆炸風險防範意識不強，主體責任不落實。員工缺乏粉塵防爆基礎知識，對粉塵爆炸危險特性、粉塵爆炸防護方法存在認識上的誤區。

2、企業粉塵防爆措施不規範

　　在建築設計、設備布局、工藝設計上存在隱患。例如粉塵爆炸危險場所設置在非框架結構的多層建構築物內或與居民區、員工宿舍、會議室等人員密集場所安全距離不足；樓層之間沒有防火門；除塵器和料倉位于室內；物料破碎（研磨）前，未按規範設置除鐵等異物的裝置。

　　除塵系統設計不規範。可燃性粉塵與可燃氣體等介質共用一套除塵系統，不同防火分區的除塵系統互聯互通；吸風罩設計不合理導致粉塵沈積嚴重；管道風速不足，除塵管路積塵嚴重；除塵器未采取爆炸防護措施；采用生産車間建構築物的部分區域作爲粉塵沈降室，或者采用磚混結構構建除塵風道；除塵系統采用正壓吹送粉塵，且未采取可靠的防止點燃源的措施；除塵管道未設置防止爆炸向室內傳播的隔爆裝置等。

　　此外，還存在粉塵清掃不足，清掃方法不正確；工藝設備未采取泄壓措施，或泄壓口設置在室內；粉塵爆炸危險場所未采用防爆電氣設備，布線不規範；未進行防靜電跨接和接地等問題。

3、監管與技術支持資源匮乏

　　部分企業一線監管人員配備不足，缺乏真正懂粉塵防爆的專家和技術服務人員。部分監管人員對粉塵涉爆企業的基本情況了解不足，無法識別出重大隱患。

4、標准體系不完善

　　對于一些識別出的重大隱患，找不到相應的標准依據。標准條款缺乏執行細則，可執行性較差。

5、基礎研究缺乏

　　缺乏粉塵爆炸特性參數和風險評估手段，以及相應的基礎研究。

"Then be kind enough to change me a dollar bill," said the stranger, drawing the beaver skin from under his coat and laying it on the counter. The nondescript individual whom we saw among the passengers early in the voyage had joined the party, and heard the story of Captain Hunting's[Pg 68] whale. When it was ended, he ventured to say something on the subject of whaling. "But if she should be at Wiggins--" "I prayed for you." Second. Impact wheels, driven by the force of spouting water that expends its percussive force or momentum against the vanes tangental to the course of rotation, and at a right angle to the face of the vanes or floats. "So this brave lady succeeded in getting the sentence of death withdrawn. But the Germans wanted to torture their wretched prisoners on any or no plea. They were placed near the church wall, kept standing there all night, were told that they would be shot by and by, and threatened by the soldiers with their bayonets. "Yes, men, what the gentleman says is true." But a profounder analysis of experience is necessary before we can come to the real roots of Plato’s scheme. It must be remembered that our philosopher was a revolutionist of the most thorough-going description, that he objected not to this or that constitution of his time, but to all existing consti254tutions whatever. Now, every great revolutionary movement, if in some respects an advance and an evolution, is in other respects a retrogression and a dissolution. When the most complex forms of political association are broken up, the older or subordinate forms suddenly acquire new life and meaning. What is true of practice is true also of speculation. Having broken away from the most advanced civilisation, Plato was thrown back on the spontaneous organisation of industry, on the army, the school, the family, the savage tribe, and even the herd of cattle, for types of social union. It was by taking some hints from each of these minor aggregates that he succeeded in building up his ideal polity, which, notwithstanding its supposed simplicity and consistency, is one of the most heterogeneous ever framed. The principles on which it rests are not really carried out to their logical consequences; they interfere with and supplement one another. The restriction of political power to a single class is avowedly based on the necessity for a division of labour. One man, we are told, can only do one thing well. But Plato should have seen that the producer is not for that reason to be made a monopolist; and that, to borrow his own favourite example, shoes are properly manufactured because the shoemaker is kept in order by the competition of his rivals and by the freedom of the consumer to purchase wherever he pleases. Athenian democracy, so far from contradicting the lessons of political economy, was, in truth, their logical application to government. The people did not really govern themselves, nor do they in any modern democracy, but they listened to different proposals, just as they might choose among different articles in a shop or different tenders for building a house, accepted the most suitable, and then left it to be carried out by their trusted agents. We've accepted, so please don't object, Daddy dear. heat of the going they get so breathless and panting that they lose The young prince then goes on his way in search of the magical flower. He is about to rest awhile in a cavern, but at the moment when he lies down on a stone it is transformed into a monster made of bladder, which rears itself enraged in the air with a trumpet-cry. By good luck the king's son calls upon the aid of the prophet Suleiman, whom the dragon also reveres, and the pacified monster conveys Tazulmulook to the garden of Bakaoli, and, moreover, gives him a ring which will be a talisman in danger. But the minister still refused to see it. He looked him very squarely in the eyes now, however. "See here, I am going to take lemon pop, my friend," he said. Nevertheless she decided that it might be best to tell her husband, and she did so as they sat together by the fire after the moon had risen into the small stretch of sky above the mountain peaks. They had bought a live sheep that day from a Mexican herder who had passed along the road, and they were now cutting ribs from the carcass that hung from the branch of a near-by tree, and broiling them on the coals. Felipa finished an unimpassioned account of the afternoon's happenings and of Alchesay's advice, and Landor did not answer at once. He sat thinking. Of a sudden there was a rustle and a step among the pines, and from behind a big rock a figure came out into the half shadow. Felipa was on her feet with a spring, and Landor scrambled up almost as quickly. "The one built of poles? Yes." "On Saturday, July 30, Dr. Johnson and I took a sculler at the Temple-stairs, and set out for Greenwich. I asked him if he really thought a knowledge of the Greek and Latin languages an essential requisite to a good education. JOHNSON. 'Most certainly, Sir; for those who know them have a very great advantage over those who do not. Nay, Sir, it is wonderful what a difference learning makes upon people even in the common intercourse of life, which does not appear to be much connected with it.' 'And yet, (said I) people go through the world very well, and carry on the business of life to good advantage, without learning.' JOHNSON. 'Why, Sir, that may be true in cases where learning cannot possibly be of any use; for instance, this boy rows us as well without learning, as if he could sing the song of Orpheus to the Argonauts, who were the first sailors.' He then called to the boy, 'What would you give my lad, to know about the Argonauts?' 'Sir, (said the boy) I would give what I have.' Johnson was much pleased with his answer, and we gave him a double fare. Dr. Johnson then turning to me, 'Sir, (said he) a desire of knowledge is the natural feeling of mankind; and every human being, whose mind is not debauched, will be willing to give all that he has, to get knowledge.'" Reuben did not in the least mind being flogged—it was all in the day's work—and showed scant sympathy for those fellow-criminals who cried for their mothers. Most of the cramp and stiffness had worn off, and his only anxiety was to have the thing over quickly, so that he could be home in time for supper. The nightmare had its appropriate ending. Sixty[Pg 297] dead beasts were burned in lime. Boarzell became Hinnom—it was the most convenient open space, so Reuben's herd was burned on it. From a dozen different pyres streamers of white smoke flew along the wind, and a strange terrible smell and tickling of the nostrils troubled the labourer on the westward lands by Flightshot or Moor's Cottage. The house was swimming in the light of the western moon. Its strange curves and bulges, its kiln-shaped ends, and great waving sprawl of roof all shone in a white glassy brilliance, which was somehow akin to peace. There was a soft flutter of wind in the orchard and in the sentinel poplars, while now and then came that distant night-purged scrap of song: The day was favourable for the pageant, and the houses seemed to vie with each other in the variety of their silken colours and tinselled ornaments, glowing and glittering in the morning sun. At Cornhill, indeed, the meretricious adornments of art were superseded for a brief space by the simple beauty of nature, and the eye felt a momentary relief in resting on the green grass, and the few shaded trees that covered the open ground. But this green spot was succeeded by a dense mass of dwellings covered with hangings of a richness suitable to the reputed wealth of the city merchants; here the scene was animated in the extreme,—the motions of the crowd became unsteady and irregular, as they were actuated at once by eagerness to hurry on, and a desire to linger among the rainbow diversity of hues around them, and the glowing beauty which, arrayed with costly elegance, and smiling with anticipated enjoyment, graced every open window.
