ʻO ke ala hoʻokaʻawale o ka pahu mālama cryogenic
Ka lā: Ianuali 17, 2020
1. Hoʻokaʻawale hoʻokaʻawale
ʻO nā ʻano hana hoʻokaʻawale maʻamau o ka pahu mālama cryogenic penei (i helu ʻia mai ka haʻahaʻa a hiki i ke kiʻekiʻe): ka hoʻopaʻa ʻana i ka hoʻopaʻa ʻana, ka hoʻoheheʻe ʻana i ka ʻūhā kiʻekiʻe. I kēia manawa, hoʻohana nui ʻia ka insulation stacking i ka ʻōnaehana insulation opahu waihona LNG.
2. ʻO ke ʻano hoʻokaʻawale o ka pahu mālama cryogenic LNG
2.1 ʻaʻole hoʻoheheʻe ʻia (hoʻopaʻa ʻana)
Hoʻopaʻa i ka hoʻoheheʻe ʻana: koho i ka mea wela wela me ka conductivity thermal liʻiliʻi e hoʻopiha ʻia ma ka ʻāpana e koi ana i ka insulation thermal, i mea e hoʻokō ai i ke kumu o ka insulation thermal opahu mālama cryogenic. ʻO nā ʻano o nā mea hoʻoheheʻe wela: (ʻoi aku ka maʻamau o ke ʻano o ka pua a me ka pauka).
1) polyamine ʻano pahu, polystyrene, rubber, aniani brick, perlite, etc.
2) Pauka - pearlite, etc;
3) Keʻano fiber - fiber glass, mineral wool, asbestos.
ʻO ka ʻōlelo maʻamau, ʻo ke kaupaku o ka lng cryogenic storage tank e hoʻohana i ka hulu hipa aniani, a ʻo ka pā pahu e hoʻonui i ka perlite a me ka hulu aniani elastic, a ʻo ka lalo o ka pahu e hoʻohana i nā pōhaku aniani.
2.2 hoʻokuʻu ʻia
1) Hoʻokuʻu kiʻekiʻe i ka ʻūhā.
ʻO ka hoʻohaumia kiʻekiʻe e hoʻoheheʻe i ka wahi insulation o ka pahu mālama cryogenic. Hana ʻia ia me ke keleawe, aluminika a me nā mea ʻē aʻe me ka ʻeleʻele haʻahaʻa, a hoʻonani ʻia ka ʻili o ka pahu. Mālama ʻia ka vacuum o ka interlayer e ka adsorption o ka adsorbent ma kahi haʻahaʻa haʻahaʻa.
2) Kiʻekiʻe vacuum multilayer insulation.
I mea e hōʻemi hou aku ai i ka holo ʻana o ka wela o ka pāhawewe kiʻekiʻe, ua hoʻonohonoho ʻia kahi pale radiation multi-layer e like me ka ʻili anu i loko o kahi ākea kiʻekiʻe o ka pahu waihona. Hana ʻia ka pale radiation me nā mea haʻahaʻa haʻahaʻa me ka hana noʻonoʻo maikaʻi. ʻO nā mea i hoʻohana nui ʻia he alumini foil a me ke kiʻi ʻoniʻoni polyester alumini.
3) Kiʻekiʻe vacuum multi pale insulation.
Hoʻokumu ʻia ka insulation multi-layer kiʻekiʻe ma luna o ka insulation multi-layer kiʻekiʻe. Hoʻokomo ʻia kahi pale conduction ma luna o ka paipu evaporation o ka ipu e hoʻihoʻi i ka hiki ke hoʻomaha o ke kinoea i hoʻokuʻu ʻia mai ka ipu.
4) Hoʻokuʻu ʻia i ka pauka maloʻo.
ʻO ka hoʻoheheʻe ʻana i ka pauka o ka pahu mālama cryogenic e hoʻopiha i ka hakahaka me nā mea pauka maikaʻi (a i ʻole fiber) e hoʻokō ai i ke kumu o ka insulation. ʻO nā mea pauka maʻamau ka silica gel, aerogel, pearlescent sand a pēlā aku.
He hui kūikawā ʻo Jianshen tank i ka hana ʻana i nā pahu mālama haʻahaʻa haʻahaʻa, nā pahu aila, nā pahu LPG a me nā mea hoʻokele LPG skid i kau ʻia a me nā mea lawe. Hoʻolako ʻia ka hui me nā ʻenehana loea a me nā hale hana. Inā pono ʻoe e kūʻai, e ʻoluʻolue hoʻokaʻaʻike mai iā mākou
ʻO nā ʻano hana hoʻokaʻawale maʻamau o ka pahu mālama cryogenic penei (i helu ʻia mai ka haʻahaʻa a hiki i ke kiʻekiʻe): ka hoʻopaʻa ʻana i ka hoʻopaʻa ʻana, ka hoʻoheheʻe ʻana i ka ʻūhā kiʻekiʻe. I kēia manawa, hoʻohana nui ʻia ka insulation stacking i ka ʻōnaehana insulation opahu waihona LNG.
2. ʻO ke ʻano hoʻokaʻawale o ka pahu mālama cryogenic LNG
2.1 ʻaʻole hoʻoheheʻe ʻia (hoʻopaʻa ʻana)
Hoʻopaʻa i ka hoʻoheheʻe ʻana: koho i ka mea wela wela me ka conductivity thermal liʻiliʻi e hoʻopiha ʻia ma ka ʻāpana e koi ana i ka insulation thermal, i mea e hoʻokō ai i ke kumu o ka insulation thermal opahu mālama cryogenic. ʻO nā ʻano o nā mea hoʻoheheʻe wela: (ʻoi aku ka maʻamau o ke ʻano o ka pua a me ka pauka).
1) polyamine ʻano pahu, polystyrene, rubber, aniani brick, perlite, etc.
2) Pauka - pearlite, etc;
3) Keʻano fiber - fiber glass, mineral wool, asbestos.
ʻO ka ʻōlelo maʻamau, ʻo ke kaupaku o ka lng cryogenic storage tank e hoʻohana i ka hulu hipa aniani, a ʻo ka pā pahu e hoʻonui i ka perlite a me ka hulu aniani elastic, a ʻo ka lalo o ka pahu e hoʻohana i nā pōhaku aniani.
1) Hoʻokuʻu kiʻekiʻe i ka ʻūhā.
ʻO ka hoʻohaumia kiʻekiʻe e hoʻoheheʻe i ka wahi insulation o ka pahu mālama cryogenic. Hana ʻia ia me ke keleawe, aluminika a me nā mea ʻē aʻe me ka ʻeleʻele haʻahaʻa, a hoʻonani ʻia ka ʻili o ka pahu. Mālama ʻia ka vacuum o ka interlayer e ka adsorption o ka adsorbent ma kahi haʻahaʻa haʻahaʻa.
2) Kiʻekiʻe vacuum multilayer insulation.
I mea e hōʻemi hou aku ai i ka holo ʻana o ka wela o ka pāhawewe kiʻekiʻe, ua hoʻonohonoho ʻia kahi pale radiation multi-layer e like me ka ʻili anu i loko o kahi ākea kiʻekiʻe o ka pahu waihona. Hana ʻia ka pale radiation me nā mea haʻahaʻa haʻahaʻa me ka hana noʻonoʻo maikaʻi. ʻO nā mea i hoʻohana nui ʻia he alumini foil a me ke kiʻi ʻoniʻoni polyester alumini.
3) Kiʻekiʻe vacuum multi pale insulation.
Hoʻokumu ʻia ka insulation multi-layer kiʻekiʻe ma luna o ka insulation multi-layer kiʻekiʻe. Hoʻokomo ʻia kahi pale conduction ma luna o ka paipu evaporation o ka ipu e hoʻihoʻi i ka hiki ke hoʻomaha o ke kinoea i hoʻokuʻu ʻia mai ka ipu.
4) Hoʻokuʻu ʻia i ka pauka maloʻo.
ʻO ka hoʻoheheʻe ʻana i ka pauka o ka pahu mālama cryogenic e hoʻopiha i ka hakahaka me nā mea pauka maikaʻi (a i ʻole fiber) e hoʻokō ai i ke kumu o ka insulation. ʻO nā mea pauka maʻamau ka silica gel, aerogel, pearlescent sand a pēlā aku.
He hui kūikawā ʻo Jianshen tank i ka hana ʻana i nā pahu mālama haʻahaʻa haʻahaʻa, nā pahu aila, nā pahu LPG a me nā mea hoʻokele LPG skid i kau ʻia a me nā mea lawe. Hoʻolako ʻia ka hui me nā ʻenehana loea a me nā hale hana. Inā pono ʻoe e kūʻai, e ʻoluʻolue hoʻokaʻaʻike mai iā mākou
ʻatikala hope loa:
ʻatikala aʻe:
E hoʻouna i kāu nīnau
ʻAʻole mākou e hāʻawi wale i kahi huahana maikaʻi, akā hāʻawi pū kekahi i ka lawelawe kiʻekiʻe. Inā makemake ʻoe i kā mākou huahana,
hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou ma kēia mau ala.
