Description
Technical field
The utility model relates to the hydrofuge bootstrap system used in a kind of bulk curing barn tobacco flue-curing, is applicable in multiple concentrated bulk curing barn tobacco flue-curing hydrofuge process, to the pipeline system that damp and hot waste gas recovery utilizes.
Background technology
The hydrofuge mode of bulk curing barn be adopt the air of ambient temperature and moisture under circulating fan effect through with exchanger heat exchange heat up after enter barn, replace with the hot and humid steam in barn, damp and hot waste gas is discharged from barn moisture exhausting port, thus reaches the object reducing barn humidity.
In hydrofuge process, in barn, temperature is far above the air themperature under normal temperature, for guaranteeing that in hydrofuge process barn, temperature does not decline, often need the heating load strengthening heating equipment, make normal temperature air through with heating equipment heat exchange after, energy rapid temperature increases, thus realize the baking process of " steady temperature hydrofuge " or " intensification hydrofuge ".On the other hand, the damp and hot waste gas that barn is discharged carries a large amount of heat energy and is directly discharged in air and wastes, analyze according to relevant authoritative expert, during barn hydrofuge, the thermal loss that the wet-hot steam of discharging causes accounts for the 40%-70% of the total amount of heat that fuel in Tobacco Leaf Curing produces.Reclaim the Low Temperature Wet hot waste gas that bulk curing barn fixation stage is discharged, be transferred to that changing yellow stage barn carries out heating up, steady temperature or be transferred to moisture regain indoor and carry out tobacco leaf conditioning, also can be transferred in barn that dry muscle blowing out waits for out room and tentatively get damp again.Reclaim the damp and hot waste gas of high temperature that drying muscle stage barn is discharged, be transferred in fixation stage barn and recycle.Thus reach the object reducing coal consumption, power consumption.
Utility model content
The utility model is for solving existing bulk curing barn in hydrofuge process, and the heat energy of discharge directly discharges problems such as wasting in atmosphere, provides a kind of bulk curing barn dehumidifying bootstrap system.
Bulk curing barn dehumidifying bootstrap system, this system comprises low temperature transmission pipeline, high temperature transmission pipeline, low temperature exports mozzle, low temperature imports mozzle, high temperature exports mozzle, high temperature imports mozzle, multiple control valve and current divider box; Low temperature transmission pipeline is positioned at the top between bulk curing barn heating, high temperature transmission pipeline is positioned at circulated air board version top between heating, current divider box is arranged on the outside of bulk curing barn left and right sides moisture exhausting port, the both sides up and down of described current divider box export one end of mozzle and high temperature respectively and export mozzle one end and be connected with low temperature, the other end that low temperature exports mozzle is connected with low temperature transmission pipeline, the other end that high temperature exports mozzle is connected with high temperature transmission pipeline, and described high temperature imports mozzle and low temperature imports inner side and the upside that mozzle is separately positioned on circulating fan between heating; Described multiple control valve is separately positioned on low temperature and exports on mozzle, low temperature importing mozzle, high temperature output mozzle and high temperature importing mozzle.
The beneficial effects of the utility model: native system be installed on the bulk curing barn left and right sides barn moisture exhausting port place and heating between top.Utilize gas by the characteristic of high pressure to low pressure diverging flow, when tobacco flue-curing is in changing yellow stage, the control valve of current divider box top and the bottom cuts out, and waste gas can not be displaced into transmission pipeline by this barn, but by the direct discharged air of shutter; Open (the Drazin inverse valve of high temperature transmission pipeline cuts out) when needing the Drazin inverse valve between the heating of hot barn in the low temperature transmission pipeline mozzle of top, produce negative pressure herein, the Low Temperature Wet hot waste gas of fixation stage will be inhaled into this barn and be used for heating up and steady temperature.When tobacco flue-curing is in fixation stage, the importing control valve of current divider box top low temperature transmission pipeline is opened, low temperature exhaust heat waste gas can be inhaled into low temperature transmission pipeline (having negative pressure in pipeline) whenever necessary, enter in low temperature flavescence barn and be utilized, unnecessary waste gas is then by the direct discharged air of shutter; Open (the Drazin inverse valve of low temperature transmission pipeline cuts out) when needing the Drazin inverse valve in the high temperature transmission pipeline between the heating of hot barn inside circulating fan and produce negative pressure herein,, the damp and hot waste gas of high temperature of drying muscle stage will be inhaled into this barn and be used for fixation humidity discharging.When tobacco flue-curing is in drying muscle stage, the importing control valve of current divider box bottom high temperature transmission pipeline is opened (the importing control valve of low temperature transmission pipeline cuts out), high-temperature residual heat waste gas can be inhaled into high temperature transmission pipeline (having negative pressure in pipeline) whenever necessary, enter in the lower barn of temperature and be utilized, unnecessary waste gas is then by the direct discharged air of shutter; The Drazin inverse valve Close All of Inner guide pipe between heating, this barn does not suck waste heat waste gas.
The waste heat of the damp and hot waste gas of discharging in bulk curing barn Tobacco Leaf Curing is reclaimed in this novel realization, is transferred in the barn of relatively lower temp, realizes the recycling of waste heat by pipeline.This system can reclaim the Low Temperature Wet hot waste gas that bulk curing barn fixation stage is discharged, be transferred to that changing yellow stage barn carries out heating up, steady temperature or be transferred to moisture regain indoor and carry out tobacco leaf conditioning, also can be transferred in barn that dry muscle blowing out waits for out room and tentatively get damp again.Reclaim the damp and hot waste gas of high temperature that drying muscle stage barn is discharged, be transferred in fixation stage barn and recycle.Thus reach the object reducing coal consumption, power consumption.
