Abstract
The utility model provides an improved air inlet system which comprises a drying channel communicated with an air inlet pipeline and an air outlet pipeline. The air inlet pipeline is provided with a heater. A draught fan is installed at the air inlet of the air inlet pipeline. A draught fan is installed at the exhaust port of the air outlet pipeline. The air inlet pipeline and the air outlet pipeline are communicated with a heat exchanger which is formed by overlaying staggered corrugated aluminum plates. The system provided by the utility model has the beneficial effects that the introduced cold air exchanges heat from one face with hot air laterally exhausted from the drying channel through the heat exchanger and is discharged from the other face; cold air is pre-cooled and hot air is initially cooled, so that the energy resources are greatly saved, the service life of the device is prolonged and the efficiency is improved. The hot air heat exchange device is formed by overlaying staggered corrugated aluminum plates, so that the system is small in size, large in heat exchange area and small in wind resistance.
Description
Technical field
The utility model relates to the drying system device technical field, relates in particular to a kind of improved air inlet system.
Background technology
In the manufacturing process of Kapton, the salivation film forming is an operation of most critical, this operation is mainly to dry by the polyamic acid resin that hot air circulation will salivate on steel band, after partial solvent volatilization in the polyamides propylhomoserin, formed the Polyamic Acid Film of self-supporting on steel band, and then carried out forming Kapton after imidization through the imidization stove.
In the prior art, the source of hot blast is to absorb extraneous wind through blower fan, blowing to heater enters after heating in slobbering machine oven dry road again and carries out the polyamic acid resin on steel band is dried, the temperature in oven dry road is up to 270 ℃, a large amount of solvent evaporates is arranged in the resin drying course, be transported to recycle section with hot blast by air-introduced machine after solvent evaporates and carry out solvent recovery.Hot blast (the containing solvent) temperature of drawing by air-introduced machine is greatly about more than 150 ℃, need send into the section of knocking off and carry out cooling recovery, therefore in whole production process, air intake is just can dry after needing heating to reach uniform temperature, the hot blast that contains a large amount of solvents after oven dry needs again the cooling solvent recovery of carrying out, and above-mentioned air inlet system exists some problems as follows:
1. what air-introduced machine was drawn is the hot blast that contains a large amount of solvents, and air-introduced machine all is in the hot operation state for a long time like this, therefore is easy to cause motor overheating to form short circuit and burns.
2. the overheated hot blast that contains solvent will reclaim through condenser condenses, and the hot blast of a large amount of high speeds, high heat has increased the burden of condenser by condenser, affects yield, has strengthened cost recovery
3. air inlet system needs air intake and heats use, and in the winter time, outdoor temperature is extremely low, needs electrical bar to heat from the new wind of outdoor suction, reaches technological requirement, has strengthened like this power consumption, power consumption increases.
The utility model content
For the problems referred to above, problem to be solved in the utility model is to provide a kind of improved air inlet system.
The technical solution of the utility model is as follows:
A kind of improved air inlet system, comprise the oven dry road, be communicated with intake stack and wind pipe on described oven dry road, described intake stack is provided with heater, air inlet place's installation air-introduced machine of intake stack, exhaust outlet place's installation air-introduced machine of wind pipe, described intake stack and wind pipe are communicated with heat exchanger.
Further, described heat exchanger is by stacked the forming of staggered form corrugation aluminium sheet.
Further, described oven dry road is provided with a plurality of intake stacks, and each intake stack is provided with a heat exchanger.
The beneficial effects of the utility model are: owing to adopting technique scheme, the hot blast of the oven dry road discharge that the cold wind of introducing is come in through heat exchanger and side from one side carries out after heat exchange from another side out, cold wind is preheated, hot blast is by tentatively cooling, greatly saved the energy, extend the service life of equipment, improved efficient; Hot-blast heat exchange device is to adopt stacked the forming of staggered form corrugation aluminium sheet, and volume is little, heat exchange area is large, and windage is little.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of heat exchanger of the present utility model.
Wherein: 1, oven dry road 2, intake stack 3, wind pipe
4, heater 5, air-introduced machine 6, heat exchanger
The specific embodiment
Below in conjunction with accompanying drawing, a kind of preferred specific embodiment of the present utility model is made brief description.
As shown in Fig. 1 to 2:
A kind of improved air inlet system, comprise and dry road 1, be communicated with two intake stacks 2 and wind pipe 3 on described oven dry road 1, described each intake stack 2 is provided with heater 4, air inlet place's installation air-introduced machine 5 of intake stack 2, exhaust outlet place's installation air-introduced machine 5 of wind pipe 3, described each intake stack 2 and wind pipe 3 are communicated with a heat exchanger 6, and described heat exchanger 6 is by stacked the forming of staggered form corrugation aluminium sheet.
The cold wind that the hot blast that will draw from the oven dry road 1 of slobbering machine is introduced by heat exchanger 6 and the intake stack 2 that needs heating carries out heat exchange, more than the temperature of the air intake that flows into from intake stack 2 has like this improved 30 degree, air intake through preheating further heats through heater 4 again, and the energy consumption of heater 4 reduces greatly; And the hot blast that need to reclaim is suitable cooling through also having obtained after heat exchanger 6, enters recovery system after cooling again, and this Energy Intensity Reduction and efficient that reclaims system is improved.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
