Abstract
The utility model discloses a waste heat recycling spiral drying device. A waste heat recycling system is additionally arranged on a spiral drying device, and the waste heat recycling system comprises a fan, a waste heat recycling channel and a heating device. The waste heat recycling channel is positioned on an air outlet of the spiral drying device and connected with the fan, the heating device is positioned inside an outlet pipeline of the fan, and the outlet pipeline of the fan is connected with an air inlet of the spiral drying device. A temperature sensor for indicating operation of the heating device is arranged at the air inlet of the spiral drying device, and a central air outlet and a plurality of air outlet holes are arranged on the top of the spiral drying device. The problem of waste heat wasted in drying of agricultural products can be resolved, heat can be recycled and constant temperature control of air inlet air temperature can be realized, and the waste heat recycling spiral drying device is fine in drying effect, small in occupied area, high in heat utilization rate and low in energy consumption.
Description
Technical field
The waste heat recovery that the utility model relates to a kind of heat cyclic utilization system, particularly a kind of drying equipment utilizes system again.
Background technology
At present, the hot-air seasoning processing of agriculture and forestry product is usually to drying time and dry mass having requirement, in order to shorten dry required time and to reach good dry mass, usually need to improve the gas temperature of drying equipment import department, yet, the gas temperature of the easy like this gas outlet that causes drying equipment is too high, because traditional drying equipment does not have the recycling system of heat, thereby causes energy utilization ratio low, causes the waste of the energy, less economical, be unfavorable for environmental protection and energy saving, in addition, traditional drying equipment can not be realized the monitoring of air inlet gas temperature and setting, thereby reach thermostatically controlled purpose, influence drying effect.
The utility model content
The purpose of this utility model provides a kind of recyclable spiral drying device that utilizes waste heat again, has that drying effect is good, capacity usage ratio is high and the characteristics of environmental protection and energy saving.
For achieving the above object, by the following technical solutions:
A kind of recyclable spiral drying device that utilizes waste heat is again set up a cover waste heat recovery and is utilized system again on spiral drying equipment, wherein, described waste heat recovery utilizes system to comprise blower fan, waste heat recovery passage and heater again; Described waste heat recovery passage is positioned on the exhaust outlet of spiral drying equipment and with blower fan and links to each other; Described heater is positioned at the fan outlet tube road, and described fan outlet tube road links to each other with the air inlet of spiral drying equipment; The air inlet place of described spiral drying equipment is provided with the temperature sensor that is used to indicate heater work; Described spiral drying equipment top is provided with central exhaust outlet and some humid air taps.
Preferably, described heater is a heat-generating pipe.
The utility model utilizes system again by increase by a cover waste heat recovery on spiral drying equipment, to be the gas that comes out of drying equipment top vent enter sieve to described sieve once more after waste heat recovery utilizes the recovery of system and heating again be drying equipment, utilize once more, thereby effectively utilize the waste heat in the gas that drying equipment discharges to carry out cyclic drying, effectively improved the utilization rate of heat, reduced energy consumption, reduced production cost and be beneficial to environmental protection and energy saving; In addition, can effectively the keep dry temperature constant of equipment air inlet of the temperature sensor at spiral drying equipment air inlet place satisfies the requirement of different agriculture and forestry products to baking temperature, thereby improves dry mass.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described recyclable front view that utilizes the spiral drying device of waste heat again of the utility model embodiment;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1.
Among the figure:
1, blower fan; 2, waste heat recovery passage; 3, heat-generating pipe; 4, exhaust outlet; 5, fan outlet tube road; 6, air inlet; 7, temperature sensor; 8, central exhaust outlet; 9, humid air tap; 10, spiral drying equipment.
The specific embodiment
Below in conjunction with accompanying drawing, further specify the utility model by embodiment.
As shown in Figure 1, the recyclable spiral drying device that utilizes waste heat more described in the utility model, set up a cover waste heat recovery and utilize system again on spiral drying equipment 10, wherein, described waste heat recovery utilizes system to comprise blower fan 1, waste heat recovery passage 2 and four groups of heat-generating pipes 3 again; Described waste heat recovery passage 2 is positioned on the exhaust outlet 4 of spiral drying equipment 10 and with blower fan 1 and links to each other; Described heat-generating pipe 3 is positioned at fan outlet tube road 5, and described fan outlet tube road 5 links to each other with the air inlet 6 of spiral drying equipment 10; Air inlet 6 places of described spiral drying equipment 10 are provided with the temperature sensor 7 that is used to indicate heat-generating pipe 3 work; Described spiral drying equipment 10 tops are provided with central exhaust outlet 8 and some humid air taps 9.
Hot blast enters spiral drying equipment 10 and rotation rising from air inlet 6, material in the drying equipment is carried out drying, form humid air after absorbing the moisture in the material, wherein a part of humid air is discharged from central exhaust outlet 8, another part humid air is discharged from the humid air tap 9 at drying equipment top, thereby both satisfied the exhaust needs, hot-air is evenly risen in drying equipment; Blower fan 1 sucks waste heat recovery passage 2 from the air that exhaust outlet 4 will still have surplus heat, there is air inlet 6 to enter spiral drying equipment 10 once more after heat-generating pipe 3 heating through being positioned at fan outlet tube road 5, but and the temperature of the temperature sensor 7 at-once monitor air inlets that are provided with at air inlet 6 places, thereby operating switch according to processing needs control heat-generating pipe 3, reach the constant purpose of control intake air temperature, guarantee dry mass.
Claims (2)
1. a recyclable spiral drying device that utilizes waste heat again is characterized in that, sets up a cover waste heat recovery and utilize system again on spiral drying equipment, and wherein, described waste heat recovery utilizes system to comprise blower fan, waste heat recovery passage and heater again; Described waste heat recovery passage is positioned on the exhaust outlet of spiral drying equipment and with blower fan and links to each other; Described heater is positioned at the fan outlet tube road, and described fan outlet tube road links to each other with the air inlet of spiral drying equipment; The air inlet place of described spiral drying equipment is provided with the temperature sensor that is used to indicate heater work; Described spiral drying equipment top is provided with central exhaust outlet and some humid air taps.
