Fly dota: tsananguro, akafanana, GOST ratings uye kunyanya kushandiswa

Panguva combustion tsvina iri vanowanika, makatumidzwa madota nedota. Pedyo yamavira iiswe chaiwo mano, mubati nezvimedu izvi. Ivo akapararira zvinhu rine vomumatunhu zvishoma pane 0.3 mm.

Chii Nhunzi nedota?

Fly dota - zvinhu wakaisvonaka navaduku PARTICIPLE hukuru. Zvinonzi akaumba panguva combustion zvokufonongonwa rinochiwedzera pa akakwidziridzwa tembiricha (800 madhigirii). Zviri 6% pakati unburnt zvinhu uye kusvikira pakuguma simbi.

Fly dota akaumba panguva combustion kuti chicherwa tsvina izvo zvinowanikwa mafuta. zvirimo dzakasiyana kuti zvakasiyana zvinhu. Somuenzaniso, mudondo zviri Nhunzi dota 0.5-2% zvachose, ari mafuta peat 2-30%, uye mune lignite uye marasha 1 - 45%.

mutambo

Fly dota akaumba panguva combustion. Properties ane pfuma anogadzirwa boilers yakasiyana avo vakasikwa murabhoritari. kusiyana izvi sei mumuviri uye zvemakemikari maitiro uye sezvamunoita. Zvikurukuru kana combustion rinowanikwa muchoto utsotso chicherwa zvinhu huni, iyo inosvitsa chimiro unburnt zvinoriumba rinoumba. Izvi zvinodaidzwa kunzi zvemaziso unburned kabhoni, inobatanidzwa nokuwedzera muchoto tembiricha kuti 800 madhigirii uye pamusoro.

anokosha mano, izvo zvinogona kuva marudzi maviri rokuchera nhunzi dota zvinodiwa: zvemaziso uye magetsi. In mashandiro GZU akashandisa yakawanda mvura (10-50 mamita ³ mvura pa 1 tani kuti nemadota). Izvi zvinonyatsooneka drawback. Kubuda ezvinhu akadaro, shandisa neizvi hurongwa: mvura pashure rokuchenesa kubva nemadota nezvimedu kuzodzosera anopinda huru mashandiro.

Key Features

• Workability. The duku zvacho, chikuru simba nhunzi nedota. Kusanganiswa nemadota kunowedzera homogeneity pamusoro chesamende musanganiswa uye ayo arambe achirema, kunonatsiridza chiputiriso uye anoderedza vachisanganisa mvura kudyiwa zvakaenzana workability.

Zvichienderana unhu uye zvimwe mafomu 4 mhando nemadota - kubva I kusvikira IV. Uye vokupedzisira mhando Nhunzi dota yaishandiswa kongiri zvivako, iyo inoshandiswa munharaunda utsinye.

kubhururuka dota kugadzira

Nekuti zvakafunga indasitiri anowanzodanwa kushandiswa mbishi Nhunzi dota (pasina kukuya, kuongorora, etc.).

Panguva combustion dota aumba. Chiedza uye zviduku zvacho nokuda inofamba iri flue magasi vakatakudzwa kubva combustor uye akabatwa chaiwo filters zolosborniki. nezvimedu Ava nhunzi nedota. The mugove yasara anonzi yakaoma padurunhuru vakasarudzwa.

Relations pakati Mapato kunoenderana mhando huni, uye magadzirirwo zvaidiwa zvikuru muvira:

• anyatsonzwisisa nokubviswa gang ndiyo 10-20% dota;
• mura gang kubviswa - 20-40%;
• nedutu-mhando yamavira - 90%.

Munguva kubudiswa dzedenga kupinda gang tudonhwe chin'ai nemadota.

Fly dota akaoma kuongorora nguva dzose arongwe nezvikamu nokupesvedzera minda yemagetsi kuti vakasikwa filters. Naizvozvo, hakusi akakodzera kushandiswa.

Kuderedza kurasikirwa zvinhu panguva calcination (5%) vanobhururuka dota fanira homogenized uye arongwe maererano zvikamu zviduku. The dota inopfurwa apo rukutu reactivity marasha rine kusvika 25% of combustible nezvakasanganiswa. Saka, zviri zvakare anomufumisa uye kushandiswa sezvo simba sehuni.

Apo kushandiswa Nhunzi nedota?

Ash zvinowanzodavirwa kushandiswa munyaya dzakasiyana-siyana zvoupenyu. Izvi zvingangova kuvaka, kurima, indasitiri, kutsvinda

In pagadzirwe mamwe kongiri kushandisa ndege nedota. Chikumbiro pakuti ayo mhando. Granular dota inoshandiswa mugwagwa kuvaka pamusoro kupaka nhandare, MSW okuchengetera nzvimbo, bhasikoro migwagwa, embankments.

Fly dota yakaoma chokunyengera inoshandiswa kusimbisa ivhu sezvo yakazvimirira astringent uye nokukurumidza achiomesa fuma. Rinogonawo kushandiswa kuvaka dikes, madhamu nedzimwe waterworks.

Nokuti kugadzirwa hydraulic kongiri nedota rinoshandiswa senzira samende womutariri (25%). Sezvo filler (zviduku) zvinosanganisira nedota pakuburitswa kwacho uye cinder kutigumbura rakashandiswa pakuvaka masvingo.

Zvinowanzoshandiswa kugadzirwa furo. Kusanganiswa dota iri chesamende kunovhengana anowedzera ayo aggregative pakusimba.

Ash rinoshandiswa senzira potashi fetiraiza mune zvokurima. Ivo ane potassium muchimiro potashi, riri nyore soluble mumvura uye kuwanikwa miti. Mukuwedzera, akapfuma dota nevamwe zvinovaka muviri: phosphorus, magnesium, sarufa, calcium, manganese, Boron, micro uye makro okunze. Kuvapo calcium carbonate inoita padurunhuru kuderedza ivhu acidity. The dota inogona kuitwa dzakasiyana mumunda mushure kurima, kuberekesa nayo pristvolovye miti anotevera nemiti, uyewo dira Mafuro uye mafuro. Hatina kutokurudzira kushandiswa nemadota pamwe nemamwe makemikari kana chicherwa fetiraiza (kunyanya phosphorus).

Ash rakashandiswa sanitization pasina mvura. It anowedzera ph uye kubaya tusingaoneki. Rinoshandiswa nenzira restrooms, uyewo munzvimbo tsvina sludge.

Kubva ose pamusoro payo inogona akapedzisa pamusoro akasiyana kushandisa zvinhu zvakadai Nhunzi nedota. The mutengo nokuti zvichisiyana 500 rubles. por tani (makuru Wholesale) kusvika 850 rubles. Zvinofanira kucherechedzwa kuti kana uchishandisa vaizviona hurukuro kubva kumatunhu mutengo kure anogona siyana yekudyidzana.
