The utility model discloses an automatic drying temperature control device which is applicable to drying operation in industrial production and reaction process requiring automatic temperature control. The automatic drying temperature control device comprises a heat exchanger, an air inlet pipe of the heat exchanger is provided with a steam inlet valve, two steam condensed water valves sequentially serially connected are arranged on a condensed water pipe of the heat exchanger, a bypass valve is connected with the two steam condensed water valves in parallel, a pneumatic adjusting valve is arranged between the two steam condensed water valves, and the condensed water pipe is provided with a drain valve. The automatic drying temperature control device is applicable to drying operation in industrial production and reaction process requiring automatic temperature control, steam can be effectively utilized, steam loss can be reduced, and resource saving, energy saving and consumption reduction can be achieved.
Description
Technical field
The utility model relates to a kind of automatic temp controller, is applicable to drying operation in Chemical Manufacture and other needs the course of reaction of automatic control temperature control.
Background technology
Existing drying system adopts the mode of steam indirect air to carry out drying to wet feed and removes moisture.Drying system mainly is made of blower fan, heater, steam control valve, cyclone separator, deduster.
The control of existing drying system temperature adopts the mode of manual adjustments steam (vapor) outlet valve aperture to realize, due to the even artificial factors such as maloperation of some unescapable time errors, causes the drying system temperature to float frequent.The unsettled temperature phenomenons such as occurring glutinous material, oven dry are irregular, wet feed caking when causing the wet feed oven dry of floating deal with and can consume a large amount of manpowers, time, delay the normal production in workshop.In addition, because drain valve is not installed at the steam (vapor) outlet valve place of heater, when causing manual adjustments steam (vapor) outlet valve, the in line phenomenon of steam is arranged, the waste resource has increased the Workshop Production cost virtually.
Summary of the invention
The purpose of this utility model is to provide the automatic temp controller in a kind of drying system, to solve the defective that in former drying course, the temperature manual control mode exists and to solve the waste of steam phenomenon.This apparatus structure is simple, can realize that the temperature of drying course is controlled automatically.
The utility model is realized in the following manner:
A kind of oven dry automatic temp controller, comprise heat exchanger, the heat exchanger admission line is provided with the steam admission valve, the heat exchanger condensate pipe is provided with the steam-condensation penstock of series connection successively, with two steam-condensation penstock by-passing valves that are provided with in parallel, be provided with pneumatic control valve in the middle of two steam-condensation penstocks, condensate pipe is provided with drain valve.
When this device uses, at first set the temperature upper limit limit value of PID device, connect the source of the gas of pneumatic control valve, and guarantee that the steam-condensation penstock is in opening, by-passing valve is in closed condition.
Drying system is driven constantly, opens the steam inlet valve, gives the air preheat that enters in heat exchanger.
Do not reach the lowest temperature value of setting when the air by heat exchanger before, pneumatic control valve is in closed condition, so that system is rapidly heated; When the air by heat exchanger reached the temperature upper limit of setting, pneumatic control valve was opened in proportion, and exhaust steam condensed water and vapour mixture float in range of set value to guarantee temperature.
When the mixture of steam and steam condensate (SC) passed through drain valve, steam and its condensed water were separated, only with the condensed water discharge pipe road, removed the condensation water collection tank; Can exhaust steam, thus the in line wasting phenomenon of the steam when having avoided former drying mode.
Wherein, pneumatic control valve and PID system interlocking, its valve opening is by PID system auto-adjustment control, opening and closing in formulating temperature range.The pneumatic control valve source of the gas is provided by 0.4-0.5MPa compressed air.Drain valve separates steam with steam condensate (SC), and makes steam condensate (SC) discharge system, to improve the utilization ratio of steam.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment;
In figure, 1, the steam admission valve, 2, heat exchanger, 3, the steam-condensation penstock, 4, by-passing valve, 5, pneumatic control valve, 6, drain valve.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As shown in Figure of description 1, the oven dry automatic temp controller that the utility model relates to mainly comprises heat exchanger 2, steam admission valve 1, steam-condensation penstock 3, by-passing valve 4, pneumatic control valve 5, drain valve 6.
The temperature upper lower limit value of PID device is set as 80～95 ℃; Connect the source of the gas of pneumatic control valve 5, and guarantee that bleed pressure is between 0.4～0.5MPa; Open steam-condensation penstock 3 and close by-passing valve 4.
Open steam inlet valve 1, begin simultaneously to the interior air-supply of heat exchanger 2.
Regulate material loading speed and other factors that affects drying effect in drying course.
During lower than 80 ℃, pneumatic control valve 5 is in closed condition, so that system is rapidly heated when the air themperature by heat exchanger 2; During higher than 95 ℃, pneumatic control valve 5 is opened in proportion when the air by heat exchanger 2, and exhaust steam condensed water and vapour mixture are unsteady in range of set value to guarantee temperature.
When the mixture of steam and steam condensate (SC) passed through drain valve 6, steam and its condensed water were separated, only with the condensed water discharge pipe road, removed the condensation water collection tank; Can exhaust steam, thus the in line wasting phenomenon of the steam when having avoided former drying mode.
This device is applicable to drying operation in Chemical Manufacture and other needs the course of reaction of automatic control temperature control.Can effectively utilize steam, reduce steam loss, be conducive to economize on resources, save energy and reduce the cost.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done are within all dropping on protection domain of the present utility model.
