Working method of the utility model for when drying sludge is as follows:
1) sludge operational process
Sludge pours into sludge crusher, and the mud granule that partial size is 8~25mm is made, from the discharge port of sludge crusher into
Sludge is delivered to the track conveyor of fluidized bed dryer by the first screw conveyor by the material mouth for entering the first screw conveyor
On, sludge uniform drawout on crawler belt.The high pressure-temperature generated with the advance of crawler belt and bottom air distribution plate is dry to be done
The injection of dry medium, mud granule are blown afloat, and the state of fluidisation is formed.The speed of crawler belt conveying is defeated according to drying time and crawler belt
Captain's degree is sent to determine.Sludge is delivered to the star-shaped discharge valve of outlet, eventually off drying system.
2) the heat pump course of work: the working medium of low temperature drying forms high temperature and pressure working medium after compressor compresses, and entrance is cold
Heat release becomes cryogenic high pressure working medium after condenser, and condenser is by the heat dried medium of release, the temperature after expansion valve release
Degree continues to reduce, and after evaporator, the heat done in miscellaneous medium is absorbed the state for turning again to low-temp low-pressure by working medium.
B-1) the course of work (the case where not needing auxiliary heating) of dried medium
Open 6#Throttle valve 76,8#Throttle valve 78,1#Throttle valve 71,2#The dried medium of throttle valve 72, high temperature drying is passed through
First air pressure pump 5 formed high pressure dried medium, into air distribution plate after equipped with mud granule crawler belt below release formed high speed
Air-flow, mud granule are blown afloat the state to form fluidisation by air-flow, and dried medium takes away the moisture in mud granule and enters dedusting dress
It sets and is dusted.When the temperature containing wet dried medium is higher than 15 DEG C of its dew-point temperature containing humid gas or more, without auxiliary
Heating.Low temperature enters guide shell containing humid gas and flows downward, quilt after the retention cover in the biggish dust collision inertia retention area of partial size
Retention, rolls down along wall surface in the second screw conveyor 43 fallen under ash bucket, and thinner dust can enter with air-flow
Inertia retains in area, and under cloth filtration, tiny dust is also trapped simultaneously.It is purified to enter steaming containing wet dried medium
Device cooling is sent out, condensation of water, which is collected, excludes drying system, and the dried medium of low temperature drying enters condenser and is heated, and entrance is next
A circulation.
B-2) the course of work (needing the case where assisting heating) of dried medium
Open throttle valve 6#Throttle valve 76,8#Throttle valve 78,1#Throttle valve 71,2#Throttle valve 72.The dry of high temperature drying is situated between
Matter by the first air pressure pump 5 formed high pressure dried medium, into air distribution plate after in drier release form high-speed flow, sludge
Particle is blown afloat to form fluidized state by air-flow, and dried medium, which takes away the moisture in mud granule and enters dust-extraction unit, to be dusted.
When the temperature containing wet dried medium is less than or equal to more than its dew-point temperature containing humid gas 15 DEG C, need to open auxiliary heat system
System.Open 5#Throttle valve 75,4#Throttle valve 74,3#Throttle valve 73, opens the second air pressure pump 6, and the dried medium of high temperature drying passes through
Auxiliary thermally induced flow cover introduces between guide shell and inertia retention area, and it is low containing humid gas containing humid gas to be mixed to form medium temperature with low temperature, leads to
The temperature in monitoring inertia retention area is crossed, adjusts 5#Throttle valve 75 meets the flow of the high temperature drying dried medium introduced most
The temperature of whole combination drying medium is higher than 15 DEG C of its dew-point temperature or more, prevents from condensing on cloth bag containing wet dried medium.Remaining
Part is consistent in the process for being not turned on auxiliary heating.
3) blowback process: when cloth bag inside and outside differential pressure reaches cloth bag limit pressure difference (such as 2000Pa), or in a setting
After good blowback end cycle (such as operation is 3 hours full), need to carry out blowback.Close 8#Throttle valve 78,5#Throttle valve 75, is opened
Open 7#Throttle valve 77,3#Throttle valve 73 opens electromagnetic impulse valve 79, opens the second air pressure pump 6, makes the dried medium of high temperature drying
Into the cloth bag to blowback, cloth bag is expanded because of blowback air-flow, be adhered to cloth bag outer surface dust fall under ash bucket second
In screw conveyor 43.The pressure of blowback air-flow is 500~600kPa, blowing time interval 60s or so, is blown the primary time
It is 0.1~0.2 second, blowing number is 5 times.It, can be real by adjusting each dust removing units throttle valve open and-shut mode during blowback
Now part dust removing units reverse gas cleaning, part dust removing units continue dedusting.
The foregoing is merely the specific implementation cases of the utility model patent, but the technical characteristic of the utility model patent is simultaneously
Not limited to this, in the field of the utility model, made changes or modifications all cover any those skilled in the relevant art
Among the scope of the patents of the utility model.
