The vertical preheater of the utility model comprises cylindrical shell, feeding device, distribution device, support, hot hopper, device for discharging, its feature: cylindrical shell is that an inner wall section is for circular, also rectangle, polygon, oval-shaped inside are the vertical structure body of cavity, material places in the cylindrical shell cavity, and it is generally made with steel.
On barrel wall, the top of hot hopper offers the import of thermal source gas, when the above thermal source gas feed of 2 or 2, is located on the sustained height of barrel wall, and evenly distributes, after thermal source gas enters the cylindrical shell cavity, with material generation heat exchange.
Is provided with the flared structure body consistent by big young direction down suitable for reading in the cylindrical shell, suitable for readingly is connected with cylinder inboard wall with the cylindrical shell vertical centre,
Also be provided with the pyramidal structure body consistent in the cylindrical shell with the cylindrical shell vertical centre by up-small and down-big direction, bullet is fixed by supporting leg and cylindrical shell or support, be positioned at flared structure body below suitable for reading at the bottom of the awl of bullet, the top of hot hopper, and the passage that has material to fall between the hot hopper.
Charge door and tail gas outlet are arranged at the cylindrical shell top, and the top of charge door connects with feeding device, and the below connects with distribution device; Vertical preheater is when negative-pressure operation, if cylindrical shell is a circular cross-section, feeding device can adopt the two turnover panel discharging air valves electronic or pneumatic actuator is controlled, or adopts the level-sensing device control discharging airlock of material level up and down.Vertical preheater is when positive pressure operation, if cylindrical shell is rectangle or elliptic cross-section, feeds in raw material and is finished by a reciprocating material distributing machine, if cylindrical shell is a circular cross-section, can adopt rotary distributing device or cone-shaped cloth device or disc type distributing device.
Hot hopper is big, a following young bucket shape container suitable for reading, is positioned at the bottom of cylindrical shell, and end opening is connected with device for discharging, and it is consistent with the cylindrical shell vertical centre, is fixed on support or the cylindrical shell.Hot hopper is heat exchange chamber with top.
Device for discharging is an electro-vibrating feeder with temperature resistant encapsulation function, or garden dish feeding machine, or the chain-plate type batcher, and it can control the material after the preheating preheater that draws off of the amount of unloading uniformly.
Stent support preheater and the carrying material total weight, it can be made by concrete or steel construction.
Refractory material and heat-insulation and heat-preservation material are all adopted in the position that preheater contacts with high-temperature gas, high-temperature material.
When the vertical preheater of the utility model is realized lump material or granular material and hot gas heat exchange, material is more abundant preheating time, the efficient of heat exchange is higher, the exhaust temperature of tail gas can be reduced to below 150 degree Celsius, structure is simpler, breakdown rate is very low, and operation and control are invested more and economized easily.
