Spray Dryer Delivery Details:
The process is composed of five parts: feeding system, heating system, drying tower system, receiving system, air delivery system, electronic control system.
(A), Spray Dryer Feed System:
Feed pump is the use of screw pump (Hangzhou Pump Factory) frequency control, it is necessary to solve the drying equipment boot warming, shutdown cooling, smooth feeding and other special requirements during operation.
Nebulizer for motor direct drive, inverter control, bearings and other accessories are imported from Japan, atomization coil speed> 120 m / s, atomization disk vertical leaves, rectangular channel feed. It can quickly and evenly, the slurry into a mist, the particle surface area increases with the clean hot air form a good heat exchange, so that the instant evaporation of water evaporated by the induced draft fan emptying.
(B), spray dryer heating system:
Drying air entering the tower through the heat exchanger is clean air filtered by air. The initial effect of the filter is non-woven, mainly to prevent insects into the tower. Medium efficiency filter made of non-woven bag, filter accuracy ≤ 5 microns, the initial air filtration resistance ≤ 15mmH2O, the main filter in the air of general dust to prevent contamination of the product. The heating process uses a heat exchanger plus electric heating to indirectly heat the filtered air to complete the heating process, with enough heat to satisfy the entire system's heat requirements.
(C) Spray Dryer Drying Chamber:
Drying chamber is composed of hot air volute, hot air distributor, air diffuser, inner tower body, tower body skeleton, outer tower body, discharging pipe, insulation material, observation cleaning door and lamp hole. From the coal-fired furnace out of the clean air through the hot air duct into the hot air spiral evenly distributed hot air distributor into the drying tower, hot air distributor according to the characteristics of the material to adjust the rotation angle, control the material residence time, adjust the angle of 0- 30 ° adjustable. Observation of a total of 1 washing door, installed in the tower cylinder, lighting installed on both sides of the drying tower door, with sufficient light to illuminate the entire tower body, drying tower cone 50 ° to meet the process requirements of the discharge convenient, Cylinder is floating suspended, free expansion in the temperature expansion, the middle of the drying tower is the channel and angle support, insulation material for the ultra-fine glass wool unilateral thickness of 100mm, the outer shell color plate production.
(D), Spray Dryer Receiving System:
One; 80% of the powder off the tower by the bottom of the fan tower.
Two; suspended in the exhaust gas in the dust by the cyclone after gas-solid separation by the fan discharge.
Three; separated after the gas containing fine dust and then into the water vapor precipitator for the final collection of dust discharged through the sewage valve, the second atomization.
(E) Spray Dryer Electronic Control System:
a, the whole set of spray drying equipment is a standard control system control tower can achieve the following functions:
b, the stable start of the motor, safe and reliable operation.
c, According to the process of the whole set of drying equipment logic, set up a variety of auxiliary equipment chain and the abnormal state of effective treatment.
d, hot air inlet system has automatic operation and manual operation of two kinds of control to ensure the normal operation of the entire equipment and product quality and stability.
e, the following type of control, the inlet temperature is a constant set of process values, the block diagram is as follows:
f, digital display instrument intuitive eye-catching. Complete output function effectively ensure the normal operation of the entire drying equipment.
g, all the figures show that the instrument uses standard communication interface transmission, conventional electrical products are used in the latest models recommended by the Electrical and Mechanical Services department, the key products are used Zhengtai brand electrical components.
