There are many types of spray drying equipment, and large equipment is mostly a tower spray dryer with a cooling machine and a vibrating fluidized bed unit.
Flat-bottomed box spray dryer: This type of dryer consists of an air filter, an inlet fan, an air heater, a phoenix box, a spray machine (nozzle), a drying chamber, a bag filter, a blower fan, etc., wherein the drying chamber For the flat bottom box structure, the air inlet is located at the high end of one end of the box, and several atomizers are installed on the same end box wall of the air inlet for horizontal parallel operation. The clean air filtered by the air filter is heated by the air blower and sent to the air heater to be divided into several uniform airflows in the air distribution box to enter the drying chamber when it is in contact with the mist-formed droplets ejected from the nozzle. The material is dry, the finished product falls into the bottom of the box, and the powder is artificially discharged intermittently. The exhaust gas is recovered from the entrained dust through a city bag filter and then exhausted through the fan. The drying process is carried out in a closed state, and the interior is under a slight negative pressure to avoid the escape of the powder umbrella. The dryer has a simple structure and is inexpensive to manufacture.

Forged carbon steel socket pipe is the most widely used connection accessories for high-pressure pipelines. It is formed by die forging blanks of round steel or steel ingots, and then machined to form by lathe. The series connection forms of socket pipe fittings include: socket welding connection ( SW), butt welding connection (BW), threaded connection (TR), and socket fittings are classified into: 45° elbow, 90° elbow, tee, cross, union, pipe clamp, plug
The pressure rating of socket and socket fittings is generally divided into 3000LB (SCH80), 6000LB (SCH160) and 9000 (XXS) in the form of socket welding and butt welding connection. The pressure grades of pipe fittings in the form of threaded connections are divided into 2000LB, 3000LB and 6000LB.
Socket fittings are generally divided into: carbon steel, stainless steel, alloy steel,
Carbon steel material: Q235, 20#, A105, etc.;
Stainless steel material: 304, 304L, 316, 316L, 321, 00Cr17Ni14Mo2, etc.;
Socket fittings are mainly used in petrochemical, medical and health, electric power, aerospace, military, fire protection, metallurgy, shipbuilding, gas, nuclear power, and environmental protection and other departments and fields that require high pressure and precise dimensions.
