FM霧化噴槍與底漆噴槍霧化特點
噴槍對涂料的橢圓形噴幅主要可分為有三層
(圖六):最里面一層為濕潤層,中間是霧化層,外面是過噴霧化層。
面漆主要是給被涂物件表面著色和裝飾作用;面漆噴槍要求顏色噴涂均勻,并且
流平性要好,所以面漆噴槍強(qiáng)調(diào)霧化效果,噴幅必須是霧化層應(yīng)比濕潤層要寬大。
底漆是填充待涂物件表面的砂痕或沙眼。底漆噴槍主要是要求填充性要好、并不
強(qiáng)調(diào)其過噴霧化太大。底漆噴槍的噴幅必須是濕潤層應(yīng)比霧化層要寬大,它只需要將
底漆均勻地噴涂到工件的待涂表面即可,霧化層應(yīng)比濕潤層窄小,尤其是過噴霧化層
更不宜過大;底漆噴涂要求填充性要好,而填充性主要靠濕潤層來完成。
電廠脫硝工程(氨水)詳細(xì)說明:
SNCR脫硝已在國內(nèi)外電廠廣泛應(yīng)用,脫硝效率高,是行業(yè)公認(rèn)的成熟可靠的脫硝技術(shù)。
SNCR反應(yīng)的溫度與鍋爐煙氣溫度恰當(dāng)符合,能夠保證高的脫硝效率。
脫硝成本低,無需對鍋爐進(jìn)行改造,鍋爐系統(tǒng)能夠正常運行。
電廠鍋爐SNCR脫硝系統(tǒng)有氨水和尿素兩種還原劑,以下是兩種系統(tǒng)的詳細(xì)介紹:
電廠SNCR(氨水)脫硝系統(tǒng)
該系統(tǒng)主要組成部分為:卸氨系統(tǒng)、儲存系統(tǒng)、清水系統(tǒng)、混合系統(tǒng)、加壓系統(tǒng)、計量系統(tǒng)、分配系統(tǒng)、霧化系統(tǒng)、沖洗系統(tǒng)、噴淋系統(tǒng)、排污系統(tǒng)、控制系統(tǒng)。
Power plant denitration project (ammonia) detailing:
SNCR denitration has been in power plant is widely used at home and abroad, the denitration efficiency is high, is the industry recognized denitration technology is mature and reliable.
SNCR reaction temperature and the boiler flue gas temperature appropriate, to ensure high denitration efficiency.
Denitration of low cost, no need for modification of the boiler, the boiler system can run normally.
Power plant boiler SNCR denitration system has two kinds of ammonia and urea reductant, here are two kinds of system in detail:
Power plant SNCR denitration system (ammonia)
Main components of the system is: the discharge of ammonia system, storage system, water system, mixing system, pressure system, measuring system, distribution system, atomization system, rinse system and spray system, sewage system, control system.
水泥SNCR(尿素)脫硝噴槍及系統(tǒng)詳細(xì)介紹:
尿素脫硝系統(tǒng)特點:
不使用催化劑,不產(chǎn)生固體廢料;
安裝快捷,操作簡單,故障效率低,停機(jī)時能夠自動清洗,能夠防止尿素溶液在管路中接近;
每一個設(shè)備部件都配有備件,能夠保證系統(tǒng)安全運行。
脫硝效率高,投入成本低。
因為尿素沒有毒害,系統(tǒng)安全系數(shù)高。
對水泥廠和水泥質(zhì)量沒有影響;
Cement SNCR (urea) denitration spray gun and the system in detail:
Urea denitration system features:
Do not use the catalyst, do not produce solid waste;
Fast installation, simple operation, low fault efficiency, downtime can automatic cleaning, can prevent urea solution in a line close to;
Each device components are equipped with spare parts, to ensure the safe operation of the system.
The denitration efficiency and low cost.
Because there is no poison, urea system high safety coefficient.
Has no impact on the quality of cement and cement;
