The present invention relates to low-order coal upgrading technical field, more particularly to a kind of upgraded coal temperature reducing humidifier.
Background technology
For low-order coal after upright furnace is pyrolyzed upgrading, the temperature of product upgraded coal is about 600 DEG C, need to be cooled to 80 DEG C
It is processed again after left and right, transports storage；At present in country's low order pyrolytic process of coal, for cooling for upgraded coal
Processing has 2 kinds of common methods：One kind is that upgraded coal is cooled to 80 DEG C or so indirectly from 600 DEG C, and shortcoming is of high cost, Er Qieleng
But the dry material after usually has dust from flying, assembles the situation of spontaneous combustion, causes follow-up workshop section's dedusting pressure very big；Another work
Skill is directly soaked in pyrolysis furnace bottom, and upgraded coal is cooled to less than 80 DEG C, and shortcoming is that water consumption is big and generation is big
Steam is measured, undressed steam carries out a large amount of dust, can be escaped in follow-up workshop section, cause production environment severe.
The content of the invention
The present invention provides a kind of upgraded coal temperature reducing humidifier, by cooling down the side being combined with humidification cooling indirectly
Method, makes the temperature of upgraded coal and moisture reach requirement, while the dust-laden steam to being produced in humidification cooling procedure is effectively located
Reason, qualified discharge；On the one hand cooling load indirectly is reduced, weight of equipment, cost and operating cost are reduced, on the other hand to carrying
Matter coal is humidified, and is played dust suppression and is improved operating environment, reduces the effect of spontaneous combustion risk.
In order to achieve the above object, the present invention is realized using following technical scheme：
A kind of upgraded coal temperature reducing humidifier, including revolution cooler, humidifier and scrubbing tower；The revolution cooler is set
Water-cooling jacket, turns round the upgraded coal entrance of the upgraded coal discharge port connection humidifier top side of cooler, and humidification motor spindle is another
Side sets upgrading coal export, and spiral conveying mechanism is set between upgraded coal entrance and upgrading coal export；Watering spray is set at the top of humidifier
Shower device, sets air intake close to humidifier one end of upgraded coal inlet side, is set at the top of the humidifier of upgrading coal export
Offgas outlet, offgas outlet connect scrubbing tower lower part tower reactor by pipeline, and scrubbing tower top sets at least two-stage spray equipment, washs
Top of tower sets net gas outlet, and wash tower bottoms set washing water out, and washing water out is by washing water circulating pipe connection spray
Device, washs and circulating pump and washings supplement entrance is set on water circulating pipe.
Gas gathering mask is set above the humidifier internal screw conveyer structure, the top of gas gathering mask is connected with offgas outlet.
Net gas outlet at the top of the scrubbing tower connects diffuse channel, and air-introduced machine is set on diffuse channel.
The upgrading coal export of the humidifier sets temperature sensor and moisture detector, temperature sensor, moisture detector
Pass through control system and the water control valve interlocked control in watering spray equipment.
Compared with prior art, the beneficial effects of the invention are as follows：
1) using the method for sub-sectional cooling humidification；Upgraded coal is cooled to 200 DEG C by 600 DEG C by cooling down indirectly, so
It is cooled down twice and humidifies by humidifier again afterwards, upgraded coal temperature is down to 80 DEG C or so, moisture reaches 5% or so, full
The requirement of sufficient subsequent technique；
2) the dust-laden steam produced in humidification cooling procedure is effectively treated, accomplishes qualified discharge；So on the one hand
The load of indirect cooling device is reduced, reduces weight of equipment, cost and operating cost, is on the other hand realizing second of cooling
While upgraded coal is humidified, play dust suppression and improve operating environment, reduce upgraded coal storage when spontaneous combustion risk；
3) factory's recycle-water i.e. processed waste water is made full use of as spray water, realizes the purpose of clean manufacturing.
