The present invention is effectively utilized high-temp waste gas, and the new wind mixed with high-temp waste gas can rely on regeneration side completely
Regeneration blower fan suction, need not be separately provided blower fan, further control realization cost and simplification and control.
The present invention is directed to existing sudden strain of a muscle dry systems chilled water coil to dehumidify new wind, new wind water capacity is the highest, needs
Temperature that will be higher and air quantity reach to dodge the defect of dry dehydration demand, are used for dodging the new of dry systems by desiccant wheel formula dehumanization method
Wind fills in mechanism, can control new wind inlet humidification at 3g/m3Hereinafter, reduce in the case of temperature and ventilation volume are done in sudden strain of a muscle full
Foot dodges dry dehydration demand, saves equipment operation energy consumption.And because humidity reduces, also the temperature of dry circulated air will be dodged from 70-80
Degree Celsius it is reduced to 50-60 degree Celsius, furthermore achieved that energy-saving and emission-reduction, reduce and dodge dry temperature and saved gas consumption,
Reducing air quantity and the most just reduce the energy consumption of blower fan, what quaternary body can add hot tank does simultaneously is less, reduces preliminary investment, enters
One step ground, because dodging the reduction of dry temperature, can reduce air quantity and the time of strong cold step, it is achieved that interlock type is energy-conservation to be subtracted then
Row, reduces overall cost.Utilizing heating arrangements, as produced by quaternary body burning, clean high-temp waste gas is as desiccant wheel machine
Regeneration thermal source, it is achieved that use in desiccant wheel by dodging the fume afterheat that in dry systems, quaternary body is discharged, it is achieved that the energy
Make full use of.Simultaneously as desiccant wheel regenerated heat source temperature is about 115 DEG C, and after quaternary body combustion heat-exchange, flue gas is 200
About DEG C, flue-gas temperature is regulated and controled by the way of new wind fills into by the present invention, regeneration side air themperature is effectively ensured constant,
Ensure the properly functioning of desiccant wheel machine.
As improving further, the heat-lightening dry systems of the present invention also includes heat pump 20, the vaporizer 24 of described heat pump 20
String is located on the strong SAPMAC method wind path 61 of described strong device for cooling, and the condenser 23 of described heat pump 20 is arranged on heating and dehumidification dress
The new wind put fills on pipeline 51.Wherein, heat pump itself similarly to the prior art, herein by the vaporizer of heat pump and condenser
Heat has the most all made substantive application, utilizes the transfer of heat, is simultaneously achieved the need of cooling and heating, is effectively increased whole
The energy of body uses level.
Specifically, described strong SAPMAC method wind path is serially connected with cooling chamber, from return side to going out in described cooling chamber
Wind side is disposed with strong cold return fan 21, vaporizer 24 and filter 22, and described strong SAPMAC method wind path enters by force through air-valve 5
The both sides of cold section 60 are to carry out the strong cold operation after heat-lightening is done.Meanwhile, described new wind fills into pipeline 51 through above-mentioned dehumidifying
The processing region of runner enters fresh air preheating room after carrying out dehumidification treatments, and described fresh air preheating room is disposed with from inlet side
Filter 52, condenser 23 and fresh-air fan 53, the air outlet of described fresh-air fan is connected to new wind and fills into mouth.New wind
Add and first pass through after dehumidifying preheating through condenser again, effectively reduce the requirement of later stage heating, it is achieved that heat total
Body distribution and effective use.Wherein, it has been arranged in parallel bypass pipe to be used as maintenance at described condenser side.
That is, replacing handpiece Water Chilling Units with one or more heat pump assembly, the vaporizer of heat pump is arranged into inside strong device for cooling, makes
Obtain cold-producing medium and strong cold air-supply direct heat transfer, strong cold air-supply is reduced to 15 DEG C by 30 DEG C, additionally the condenser cloth of heat pump assembly
Putting heat-lightening to do inside new air heating device, the heat utilizing heat pump assembly to produce dodges dry new wind.
In sum, the invention have the advantages that

The expense of combustor in the new air heating device of case.
Parameter comparison, for traditional scheme, handpiece Water Chilling Units evaporating temperature 0 DEG C, condensation temperature 45 DEG C, cold owing to only make use of
Amount, heat drains into outdoor via cooling tower, and therefore under this operating mode, the calculated performance coefficient EER of handpiece Water Chilling Units (freeze by handpiece Water Chilling Units
Amount and the ratio of compressor wasted work) it is 3.2 (without chilled water circulating pump, cooling tower energy consumption, if counting, this performance system
Can be lower), and novel for this application, and source pump evaporating temperature 8 DEG C, condensation temperature 60 DEG C, owing to native system both make use of
Source pump refrigerating capacity, make use of source pump heating capacity again, therefore under this operating mode, the calculated performance coefficient EER of source pump
(source pump refrigerating capacity and the ratio of heating capacity) is 6.4.
With strong cold air output 50000Nm3/ h, resh air requirement 25000Nm3As a example by/h, the energy input of traditional scheme is: cooling-water machine
Group power consumption is 20.2kwh, and it is 405.3kwh that combustor adds thermal energy consumption；And after applying the present invention, the energy input of whole system is
73.4kwh, it is achieved that the requirement of energy-saving and emission-reduction.
In sum, desiccant wheel is used for the dehumidifying of new wind by the present invention, effectively reduces humidity, utilizes the phase of heating arrangements
To desorbing high-temperature gas as desiccant wheel after clean burning waste gas homoiothermic, meanwhile, heat pump is utilized to release the coldest section
Heat is transferred to new wind bringing-up section, and 3 be combined with each other, and effectively reduces the dry circulated air temperature of heat-lightening, circulating load and new wind and mends
Enter amount, reduce strong cold blast rate, the requirement of strong cold wind temperature, it is achieved that the global optimization configuration of the energy, be substantially reduced energy consumption, joint
Cost-saving.
The above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, it is also possible to make some improvements and modifications, these improvements and modifications
Also should be regarded as protection scope of the present invention.
