關鍵詞:印度SS各類幹燥設備介紹

我們廣(guǎng)泛幹燥設備已發展(zhǎn)到非常專業的(de)要求,並確保以^小的能源使用效率高。縮短幹燥時間意味著減少磨損,亞麻,從而在一個較長(zhǎng)的使用壽命和顯著的成本節約。
---------------------------------
閃蒸幹燥機
閃蒸幹燥機是一種氣動係統,主要用於幹燥(zào)產品,需要去除遊離水分的。幹燥發生在(zài)幾秒鍾(zhōng)的事。濕材料被(bèi)分散到一個流的熱空氣(或氣體),把它傳送通過一個幹燥管。
從氣流(liú)中使用的(de)熱,因為它被輸送的材料幹(gàn)燥。產品采(cǎi)用旋風分離和/或(huò)袋式過濾器。通常(cháng)情況下,旋風分離(lí)器隨後通過洗滌器或袋式(shì)過濾器作^後清洗的(de)廢(fèi)氣,以滿足目前的排放要求。
因(yīn)為閃爍熄滅,即(jí)刻的表麵水分的幹燥氣體進行冷卻,而不明顯地(dì)增加了產(chǎn)品(pǐn)的溫度,升高幹燥溫度,可用於許多產品。
對於更大的熱效率和(hé)惰(duò)性需要的地方,回收廢氣的都可以使用。這可以實現我們所有的氣流幹燥係統和翻新改造(zào),對客戶現有的幹燥(zào)作業。
許(xǔ)多在^上^大的機閃蒸幹(gàn)燥器 - 一些在單個係統中的水分蒸(zhēng)發量每小時超過20噸。進氣口(kǒu)溫度範圍從200 - 1400°F(100℃ - 650℃),而氣流(liú)可以超過12萬立方英尺(200000立方米)。

Our extensive range of dryers have been developed to fullfill the professional laundry requirements of customers, and to ensure high productivity with a minimal use of energy. Shorter drying time means less wear of the linen, resulting in a longer lifetime and significant cost savings.
---------------------------------
Flash Dryer
Flash Dryer is a pneumatic system primarily used to dry products requiring the removal of free moisture. Drying takes place in a matter of seconds. Wet material is dispersed into a stream of heated air (or gas) which conveys it through a drying duct.
Using the heat from the airstream, the material dries as it is conveyed. Product is separated using cyclones, and/or bag filters. Typically, cyclones are followed by scrubbers or bag filters for final cleaning of the exhaust gases to meet current emission requirements.
Elevated drying temperatures can be used with many products since the flashing off of surface moisture instantly cools the drying gas without appreciably increasing the product temperature.
For even greater thermal efficiency and where inertisation is required, recycling of exhaust gases can be used. This can be implemented on all our airstream drying systems and retrofitted on customer's existing drying operations.
Many of the largest dryers in the world are flash dryers - some exceeding 20 tons of water evaporation per hour in a single system. Inlet air temperature ranges from 200- 1400°F (100oC -650oC) while airflows can exceed 120,000 cfm (200,000 m3/hr).

---------------------------------
Rotary Dryer
The rotary dryer is a type of industrial dryer employed to reduce or minimize the liquid moisture content of the material it is handling by bringing it into direct contact with a heated gas.
The dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern.

---------------------------------
Spray Dryer
Spray drying is a method of producing a dry powder from a liquid or slurry by rapidly drying with a hot gas. This is the preferred method of drying of many thermally-sensitive materials such as foods and pharmaceuticals. A consistent particle size distribution is a reason for spray drying some industrial products such as catalysts. Air is the heated drying media; however, if the liquid is a flammable solvent such as ethanol or the product is oxygen-sensitive then nitrogen is used.

All spray dryers use some type of atomizer or spray nozzle to disperse the liquid or slurry into a controlled drop size spray. The most common of these are rotary nozzles and single-fluid pressure swirl nozzles. Alternatively, for some applications two-fluid or ultrasonic nozzle are used. Depending on the process needs drop sizes from 10 to 500 micron can be achieved with the appropriate choices. The most common applications are in the 100 to 200 micron diameter range.

The hot drying gas can be passed as a co-current or counter-current flow to the atomiser direction. The co-current flow enables the particles to have a lower residence time within the system and the particle separator (typically a cyclone device) operates more efficiently. The counter-current flow method enables a greater residence time of the particles in the chamber and usually is paired with a fluidised bed system

---------------------------------
Drum Dryer
Our Rotary Drum Dryers are best suited for drying heat sensitive chemicals, food and pharmaceutical products.

Due to short contact time with the- hot drum the product can be dried at atmospheric pressure without thermal degradation and change of properties. For extremely heat sensitive products we provide dryers operated under vacuum where the product is dried at much lower temperatures thereby retaining its properties and physical appearance. Our dryers are fabricated to maintain the structural stability during the drying operations due to the appropriate metallurgy of the components.

The Drum of Rotary Drum Dryer is fabricated out of boiler quality plates/stainless steel/copper plates. The drum is ground on the drying surface and provided with a hard cromium deposition and superior finish for best drying efficiency and preventing residual dried product left over on drum surface after the scraping stage. The drum is provided with hollow shafts for entry of steam/heating fluid.

---------------------------------
Rotary Vacuum Filter
Rotary vacuum filter drum consists of a drum rotating in a tub of liquid to be filtered.
The technique is well suited to high solids liquids that would blind or block other forms of filter. The drum is pre-coated with a filter aid, typically of diatomaceous earth (DE) or Perlite. After pre-coat has been applied, the liquid to be filtered is sent to the tub below the drum. The drum rotates through the liquid and the vacuum sucks liquid and solids onto the drum pre-coat surface, the liquid portion is "sucked" by the vacuum through the filter media to the internal portion of the drum, and the filtrate pumped away. The solids adhere to the outside of the drum, which then passes a knife, cutting off the solids and a small portion of the filter media to reveal a fresh media surface that will enter the liquid as the drum rotates. The knife advances automatically as the surface is removed.
---------------------------------
Multi Stage Turbulent Contractor
A treatment system for a wastewater influent containing having a facultative tank with a vertically disposed lower anaerobic treatment zone, a middle microaerophilic treatment zone and an upper aerobic treatment zone. A baffle extends vertically in the tank in at least portions of said upper and middle zones to define a vertically extending influent section to receive the influent and an effluent section. The heavier biosesolid components of the wastewater received in the influent section drop from the bottom thereof into the lower anaerobic zone for treatment and the lighter components exiting from the influent section flow into the effluent section to rise therein and be treated as they flow upwardly through said microaerophilic and aerobic zones. A lift tube for an inlet above the anaerobic zone and lifts liquid and lighter solid components into the air for aeration and flow back into the influent section. To improve efficiency, biosesolids are added to the wastewater.
