Description
Technical field
This utility model relates to dehydrator field, is particularly well-suited to oven drying at low temperature, heat recovery one high temperature air
Source heat pump tower drier.
Background technology
Tower drier is also known as vertical drier, and it is widely used to moulded coal, cement, chemical fertilizer, Coal Chemical Industry etc. and produced
Drying to material in journey, has little, the small investment of occupation of land and stable feature.
In recent years, through constantly development and improvement, on market, visible tower drier is the most varied, Qi Zhonggong
The number of opening tower drier disclosed in the Chinese patent application of CN167361A is exactly the one in many tower driers.This stands
Formula dehydrator includes cylinder and the collet being located in cylinder and lifting circle, and collet is the cone become larger from the top down
Overlapping, it is positioned at the center of cylinder and is coaxially set with cylinder, shape between outside wall surface and the internal face of cylinder of collet
Become material channel；Lifting circle is the most diminishing tapered sleeve shape, is fixed on the internal face of cylinder and same with cylinder
Axis is arranged.When using this tower drier, material falls into cylinder and along collet and cylinder inboard wall from the top of cylinder
The material channel formed between face falls, and hot blast is passed through in collet by air inlet set on cylinder, adjacent two collets
Between gap form the outlet of hot blast, material is the hot-air seasoning that blown out by hot-blast outlet during falling.But no
It is suitable for the requirement of oven drying at low temperature.
Secondly the heat source of current most of tower driers is all to use coal-fired or combustion gas, and this heat-supplying mode is maximum
Harm be exactly high pollution, secondly discharge substantial amounts of carbon dioxide, air caused serious pollution, through dust-precipitator from drying
Machine is discharged into the EGT of air at about 100 DEG C, and waste heat waste gas directly empties and can not be recycled utilization, consumes a large amount of
