Description
Technical field
The present invention relates to a kind of solar energy utilization and waste heat recovery and utilize barn again, belong to drying tobacco device technique field.
Background technology
At present, national bulk curing barn Based Intelligent Control is popularized in an all-round way and is used bulk curing barn construction structure and baking process maturation.Existing bulk curing barn be by a wall every Heat Room and cigarette-filling house constitute, the heat that produces in the Heat Room is sent into the oven dry that cigarette-filling house carries out tobacco leaf by circulating fan, the hot-air that then contains a large amount of moistures is by cigarette-filling house's top discharge, outside air is entered by the connected entrance of Heat Room and barn upper end, absorb the heat of solar energy temperature collecting chamber and dehumidification tube, enter the barn baking again, reach waste heat recovery and utilize again; The intensive baking room of said structure has been well positioned to meet requirement in use, but also has very big problem in energy-conservation link.
And barn heat exhaustion aspect is taken the physics heat out of based on exhaust outlet, accounts for 50-75%, and wherein invalid heat consumption is up to 40-60%.Especially the invalid energy consumption of fixation stage in the tobacco flue-curing process and drying muscle stage accounts for 50% more than, so carry out heat regulation between fixation stage and drying muscle stage are to barn, can reach the effect of energy-saving and emission-reduction.And as the Guizhou of one of national tobacco leaf main producing region, sunny season in baking, it is the highest that 7-8 month percentage of possible sunshine reaches the whole year, and solar energy resources is with the obvious advantage.Therefore, transform by the basic enterprising luggage smoke-box at large-scale bulk curing barn, the waste heat recovery and the solar energy composite of hydrofuge tail gas utilize significant in the research barn flue-cured tobacco process.
The patent No. is 200620133777.6, name is called: utilize solar energy reduce coal consumption tobacco leaf condensed type barn composite set, in this patent, introduced the utilization of solar energy and the method that is recycled of heat energy, this method in the barn use truly have good energy-saving effect, can satisfy the requirement of peg baking; But along with the popularization of the tobacco leaf accumulation formula flue-cured tobacco method of loosing, carry out flue-cured tobacco with this patented technology scheme and then can not meet the demands, the reason of its failure of analysis-by-synthesis, subject matter are embodied in hot and humid gas discharging deficiency in extraneous intake deficiency, the barn.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of energy to satisfy to loose tobacco leaf to pile up baking, and heat utilization efficiency height, solar energy and barn baking hydrofuge gas waste-heat recycling barn that gas communication is good can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: solar energy and barn baking hydrofuge gas waste-heat recycling barn, it comprises cigarette-filling house and the Heat Room that a wall is separated by, on cigarette-filling house and the Heat Room, the lower end communicates, the top connected entrance of cigarette-filling house and Heat Room is the hot blast return air inlet, the bottom connected entrance is the hot blast air outlet, top at Heat Room is provided with circulating fan, upper side at Heat Room cocycle blower fan is provided with the cold wind air inlet, top in cigarette-filling house offers moisture exhausting port, on cigarette-filling house top, be connected with dehumidification tube on the moisture exhausting port, on cigarette-filling house and Heat Room, be provided with temperature collecting chamber, the body of dehumidification tube is positioned at temperature collecting chamber, the mouth of pipe is positioned at outside the temperature collecting chamber, in temperature collecting chamber, be provided with air admission hole, and temperature collecting chamber communicates with the cold wind air inlet.
The quantity of dehumidification tube is more than one, is provided with between the dehumidification tube more than at interval.
The entrance point of dehumidification tube is higher than the port of export.
Air admission hole in the temperature collecting chamber is positioned at the port of export of dehumidification tube.
Moisture exhausting port is near the Heat Room side.
On the cold wind air inlet, be provided with the cold wind shutter.
Compared with the prior art, the present invention has compared following advantage with existing intensive baking room:
1, the present invention is provided with solar energy temperature collecting chamber in cigarette-filling house with the top of heating the room, and the callable dehumidification tube of heat energy is set in temperature collecting chamber, temperature collecting chamber communicates with circulating fan cold wind air inlet, so just can utilize solar energy and discharging waste heat that the gas in the temperature collecting chamber is carried out preheating, and then make the gas temperature that enters the cold wind air inlet be higher than ambient temperature, can reduce coal-fired consumption significantly, reduce pollution emissions, it is calculated that statistics, the conventional relatively intensive baking room of employing the present invention can be energy-conservation more than 20%.
2, the air intake of intensive baking room and air-out are closely-related, and what of air-out are related to the discharging of examining moisture in the room, the particularly popularization of piling up baking method along with the leaf that looses, the amount of putting into tobacco leaf in each barn is by original 3-4 ton, rise to the 5-6 ton, in order to reach desirable cured effect, just must satisfy air intake and air-out.Turnover wind of the present invention for these reasons setting, moisture exhausting port setting are well positioned to meet requirement, guarantee that cigarette-filling house's gas inside flows, the present invention and conventional intensive baking room, the patent No. are 200620133777.6 under the identical situation of circulating fan, name is called: " utilizing solar energy to reduce the tobacco leaf condensed type barn composite set of coal consumption " (claiming the patent barn later on) compared its cold wind air inlet air quantity and is significantly higher than the patent barn, and concrete measuring wind speed please see Table one;
By table 1: the cold wind air inlet wind speed of conventional bulk curing barn and return air inlet wind speed are respectively 0.64 m/ second, 1.35 m/ seconds, and intake and return air amount ratio are about 1:2; Patent barn cold wind air inlet wind speed, return air inlet wind speed and intake, return air amount all are significantly less than conventional bulk curing barn, differ greatly; It is less that cold wind air inlet wind speed of the present invention, air outlet wind speed, intake, return air amount and conventional bulk curing barn are compared gap, within reasonable range.So the patent barn will cause barn baking ventilation dewetting not smooth, and then influence the quality of flue-cured tobacco, it can not satisfy the normal baking needs of the leaf baking of loosing.
3, the quantity of dehumidification tube is more than one, is provided with between the dehumidification tube more than at interval, can increase the heat-exchange capacity of dehumidification tube like this.The entrance point of dehumidification tube is higher than the port of export, makes things convenient for the condensed water discharging in the dehumidification tube like this.Air admission hole in the temperature collecting chamber is positioned at the port of export of dehumidification tube, can increase the preheating of air distance like this.Moisture exhausting port can increase the hydrofuge degree in the barn like this near the Heat Room side, according to applicant's test, with moisture exhausting port near the outlet air quantity of Heat Room side (near the return air door) is
0.1176, the outlet air quantity that moisture exhausting port is located near the cigarette-filling house doorway is 0.0853, by above data as can be seen, the effect that is provided with hydrofuge of moisture exhausting port position has a significant impact.
