Abstract
The utility model relates to an energy-saving type drying device which comprises a drying bin, an air heater, a wet air outlet pipe, an air inlet pipe and an air heat exchanger. The air heater is installed at the upper end of the drying bin, and is communicated with the air heater. An air inlet end of the wet air outlet pipe is communicated with the drying bin. An air outlet end of the wet air outlet pipe is installed on the air heat exchanger. The air heat exchanger is provided with a dry cold air inlet port and a wet air exhaust port. The air exchanger is communicated with the air heater through an air inlet pipe. The energy-saving type drying device has the advantages of reducing use of steam or electricity by recovering heat in wet hot air and using the heat for preheating of cold air, thereby achieving an energy-saving effect.
Description
Technical field
The utility model relates to a kind of drying unit, and concrete is a kind of energy-conserving drying device.
Background technology
Existing drying plant is when operation, by the cool ambient air heating generation heated dry air of the modes such as steam or electrical heating with access arrangement, carry out heat exchange with heated dry air and baking thing, discharge damp-heat air, constantly circulation sets requirement until baking thing humidity is reached.The existing equipment thermal losses occurs in several places: one, to baking thing transferring heat; Two, the heat that distributes to environment of equipment; Three, work in coordination with the heat that damp-heat air is discharged together.Above loss except article one be useful, all the other are all wastes, the heat that the damp-heat air that drying plant discharges carries is thermal losses the best part in drying plant, and the heat in the damp-heat air that can not recycling discharges of traditional drying plant.
Summary of the invention
For overcoming the defective of prior art, the utility model provides a kind of energy-conserving drying device.The technical solution of the utility model is: a kind of energy-conserving drying device, comprise warehouse for drying, air heater, humid air escape pipe, air inlet pipe and air heat exchanger, the upper end of described warehouse for drying is equipped with air heater, and be connected with air heater, the inlet end of described humid air escape pipe is connected with warehouse for drying, its outlet side is arranged on air heat exchanger, be provided with cold dry air air inlet and humid air exhaust outlet on described air heat exchanger, be communicated with by air inlet pipe between described air heat exchanger and air heater.
The inlet end of described humid air escape pipe and outlet side are arranged on respectively the bottom of warehouse for drying and air heat exchanger.
The periphery of described warehouse for drying is coated with insulation material.
The utility model has the advantages that: by the heat in the recovery damp-heat air, and this part heat is used for preheating of cold air, to reduce the use of steam or electricity, has reached energy-saving effect.
Description of drawings
Fig. 1 is agent structure schematic diagram of the present utility model.
The specific embodiment
referring to Fig. 1, the utility model relates to a kind of energy-conserving drying device, comprise warehouse for drying 1, air heater 2, humid air escape pipe 5, air inlet pipe 3 and air heat exchanger 4, the upper end of described warehouse for drying 1 is equipped with air heater 2, and be connected with air heater 2, the inlet end of described humid air escape pipe 5 is connected with warehouse for drying 1, its outlet side is arranged on air heat exchanger 4, be provided with cold dry air air inlet 6 and humid air exhaust outlet 7 on described air heat exchanger 4, be communicated with by air inlet pipe 3 between described air heat exchanger 4 and air heater 2.For guaranteeing drying effect, can increase air inflow, can effectively contact with the baking thing after making heated dry air enter the oven dry bin, make the humidity of the air maintenance maximum after exchange improve the utilization rate of heat with this;
The inlet end of described humid air escape pipe 5 and outlet side are arranged on respectively the bottom of warehouse for drying 1 and air heat exchanger 4, the periphery of described warehouse for drying 1 is coated with insulation material (routine techniques), reduce the oven dry bin to the environment transferring heat, come energy efficient with this;
Operation principle of the present utility model is: cold dry air enters in air heat exchanger 4 by the air inlet 6 on heat exchanger, gas through air heat exchanger 4 enters in air heater 2 through air inlet pipe 3, after heating again, gas enters the bin of warehouse for drying in air heater 2, after contacting oven dry with baking thing in bin, again enter in air heat exchanger through the humid air escape pipe, carry out reciprocation cycle, humid air is through after air heat exchanger, discharge through the humid air exhaust outlet, in figure, the direction of arrow represents the flow direction of cold dry air.
For the utility model, heat recovery effect and humidity recovering effect can reach the cold air preheating by the air heat exchanger of selection and installation unlike material, to reclaim the heat in damp-heat air, reach energy-conservation requirement.
