A kind of temperature-controlling system of vertical type drying tower
Technical field
The utility model relates to a kind of device of vertical type drying tower technical field, is specifically related to a kind of temperature-controlling system of vertical type drying tower.
Background technology
Vertical type drying tower is as the visual plant in carbonization technique flow process, for the carbon fiber after starching is dried.But since putting into operation, there is a lot of problems in vertical type drying tower.Such as: drying tower regional area electric boiling plate melts, and thermal resistance variation range is large, and the thermal resistance life-span is short, and the interior temperature control of drying tower is unstable etc.These problems have affected the normal production of company to a certain extent, have reduced production efficiency, have increased production cost, have reduced product quality.Particular problem is analyzed as follows:
1. drying tower regional area electric boiling plate melts, and by analysis, this not rationally causes because temperature control distributes.Specifically, vertical type drying tower has six layers, is but only provided with three temperature controlling points, is set in respectively on air pipeline, vertical type drying tower top and vertical type drying tower bottom.Clearly, this will cause temperature that temperature controller cannot vertical drying tower inside to carry out effective and reasonable control.Reason is: assumed bottom temperature has reached the temperature of setting, but because head temperature does not reach technological requirement, for this reason, must improve bottom temp, so that head temperature meets the demands, but superheated can cause the local electric boiling plate fusing of drying tower.
2. electrothermal resistance range of temperature is large, and thermal resistance is fragile, because effective point for measuring temperature is positioned at top and the bottom of vertical type drying tower.In the time that head temperature is suitable, bottom temp may not reach requirement, and this makes the range of adjustment of thermal resistance bigger than normal, and then makes the thermal resistance lost of life.And, due to two temperature controlling points relatively far apart, make two temperature between temperature controlling point stable not, also even not, in the winter time, this information slip terrain is more obvious.In view of this special construction of vertical type drying tower, whether the temperature that even cannot understand drying tower two to five interlayers reaches requirement.
3. the impact of product quality.Owing to only having two effective temperature controlling points, if one of them damages, another temperature controlling point also cannot use, thereby cannot carry out effective temperature control by vertical drying tower, affect product quality, and serious words cause production line to stop.
4. keep in repair, maintain difficulty large.In view of the special construction of vertical type drying tower and the simplification of control mode, can only understand its inner temperature by middle control.Due to installation site apart from each other, if thermal resistance breaks down, whole vertical type drying tower balustrade deching need be opened, workload is larger.
5. power consumption cost is higher.Owing to only there being two temperature controlling points, resistance and temperature range is larger, and power regulating eqiupment power consumption is larger, has therefore increased power consumption.
Therefore, the problems referred to above are the problems that should pay attention to and solve in the design and use process of the temperature-controlling system of vertical drying tower.

The temperature-controlling system of a kind of vertical type drying tower of the utility model, on described temperature element, set in drying tower each layer temperature required, temperature element is transmitted to signal on temp-controlling element and temperature control executive component, thereby control each layer temperature required by temp-controlling element and temperature control executive component, reach the object to drying tower partition heating.In the time that a certain or a few heating plates damage, find out and obtain by thermostat, thereby just can disconnect heating plate and damage the heater circuit of that one deck, again start drying tower temperature-controlling system, interior other each layer of drying tower is worked on.When work stops, needing repairing, as long as survey for that one deck damaging, in the short time, just can detect the heating plate of damage and substitute in time, drying tower can be put into production again.
The beneficial effects of the utility model are: the utility model is by drying tower is increased to temperature controlling point, and make to adopt the mode of parallel join between each layer of circuit, thereby reach the object that can carry out to each thermostat place layer in drying tower partition heating.And such improvement has reduced the consumption of electric weight to circuit, for user saves spending greatly.This improves maximum projecting point and is to carry out subregion temperature control, can be because of the damage of a certain or a few heating plates and have influence on the temperature of whole drying tower, and avoid heating plate to receive damage because of over-heating.And in the time that a certain or a few heating plates are damaged, can know in time the residing position of heating plate, keep in repair, also can remove the circuit of damaged layer, other layers of drying tower are proceeded to work.The utility model exquisite composition, easy to operate, the temperature control that makes drying tower inside more effectively, more even, more convenient, safer, improve the cycle of operation of equipment, reduce production cost, time saving and energy saving in maintenance process, for macrocyclic steady production provides guarantee.
