The utility model removes the moisture of blade dryer (1) inner air by heat-pump dehumidification technology, but also sufficiently
The waste heat generated using heat-pump dehumidification system carries out drying and other treatment to sludge, at the same by the blade of drying machine (1) to sludge into
Row is broken, increases mud granule heating surface area, shortens the sludge drying time.Different according to working media type, this is practical new
There are the refrigerant circulatory system, the heating medium circulatory system, air circulation system three independent closed circulation systems inside type
System.
The operation principle and process of the refrigerant circulatory system be such that first compressor (12) by refrigerant by low
Warm low-pressure gaseous is changed into the gaseous state of high temperature and pressure, and the saturated liquid of cryogenic high pressure, then warp knuckle are then converted into through condenser (7)
Stream valve (8) is converted into low-pressure gas-liquid mixture, is finally being changed into low-temp low-pressure gas-liquid mixture by evaporator (10), finally
After carrying out gas-liquid separation to refrigerant in gas-liquid separator (11), it is changed into high pressure gaseous into compressor (12),
And with this loop cycle.Wherein, compressor (12) the high temperature and high pressure gas refrigerant intermediate to condenser (7), passes through preheating
Heat exchanger (13) and heat exchanger (6) respectively to enter the air of blade dryer (1) with and heating medium progress heat exchange, be
Blade dryer provides heat and maintains mud granule within the scope of certain temperature；Precool heat exchanger device (9) and evaporator
(10) air of circulating fan (3) conveying and refrigerant are subjected to heat exchange, refrigerant vaporization heat absorption, air has high temperature change
For low temperature, reach refrigerated dehumidification effect.
The operation principle and process of the heating medium circulatory system is such that the low-temperature heat supply medium in temperature control storage tank (4)
Through circulating pump (5) be delivered to heat exchanger (6) carry out heat exchange, heating medium from low-temperature transformation be high temperature, subsequently into blade
Drying machine (1) carries out heat transfer drying to sludge, finally enters temperature control storage tank (4) and carries out temperature adjusting.
The operation principle and process of air circulation system is such that the tide of the high temperature after air filter (2) dedusting
Humid air is pumped to precool heat exchanger device (9) by circulating fan (3) and is changed into room temperature humid air, then in evaporator (10) with
Heat exchange occurs for cryogenic refrigeration medium, is changed into low temperature drying gas, while air vapor is condensed into liquid discharge, last low
Warm dry air, which enters preheating heat exchanger (13), becomes high temperature dry air.
