Description
Technical field:
The utility model relates to a kind of nitrogen making and injection equipment, particularly a kind of nitrogen making machine temperature control system.
Background technology:
In membrane separation nitrogen making machine, the intake air temperature of film group is very crucial parameter, and rationally accurately the intake air temperature of controlling diaphragm group can ensure that film group is run with higher separation efficiency, and greatly can extend the serviceable life of film group.The process of gas path of the temperature control system of current nitrogen making machine is as follows: air compressor machine produces the pressurized air of high temperature, the pressurized air of high temperature enters air cooler and cools, enter cooling driers through the cooled pressurized air of air cooler and carry out cooling de-watering, enter filter set from cooling driers pressurized air out to filter, pressurized air after filtering enters after heat exchanger heats and enters film group entrance.Heat exchanger is the decline of whole flow process, is also temperature controlled key node.At present in the temperature control system of nitrogen making machine, heat exchanger employing electrical heating and heating water bath two kinds of modes, be equipped with temperature sensor and PLC controls, and can reach good temperature control effect.But these two kinds of modes all need to consume extra energy, add the cost that equipment runs.
Utility model content:
The technical problems to be solved in the utility model is to provide a kind of nitrogen making machine temperature control system, the arrangement achieves can controlling diaphragm group intake air temperature accurately, heat exchanger does not need extra energy ezpenditure, energy-conserving and environment-protective simultaneously, greatly reduces the operating cost of equipment.The heat exchanger overcome in the temperature control system of existing nitrogen making machine needs to consume extra energy, increases the deficiency of the cost that equipment runs.
Technical solution adopted in the utility model is: a kind of nitrogen making machine temperature control system, comprises air compressor; Air compressor is connected with solenoid valve with the high-temperature gas entrance of heat exchanger respectively, solenoid valve is all connected with air cooler with the high-temperature gas outlet of heat exchanger, air cooler is connected with cooling driers, cooling driers is connected with filter set, filter set is connected with the cryogenic gas entrance of heat exchanger, the cryogenic gas outlet of heat exchanger is connected with film group by pipeline, pipeline between the cryogenic gas outlet and film group of heat exchanger is provided with temperature sensor, and temperature sensor is all connected with PLC with solenoid valve.
The beneficial effects of the utility model are: the utility model, thus can controlling diaphragm group intake air temperature accurately owing to have changed whole process of gas path, and heat exchanger does not need extra energy ezpenditure, energy-conserving and environment-protective simultaneously, greatly reduces the operating cost of equipment.
Accompanying drawing illustrates:
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, a kind of nitrogen making machine temperature control system, comprises air compressor 1, air compressor 1 is connected with solenoid valve 8 with the high-temperature gas entrance of heat exchanger 5 respectively, solenoid valve 8 is all connected with air cooler 2 with the high-temperature gas outlet of heat exchanger 5, air cooler 2 is connected with cooling driers 3, cooling driers 3 is connected with filter set 4, filter set 4 is connected with the cryogenic gas entrance of heat exchanger 5, the cryogenic gas outlet of heat exchanger 5 is connected with film group 6 by pipeline, pipeline between the cryogenic gas outlet and film group 6 of heat exchanger 5 is provided with temperature sensor 9, temperature sensor 9 is all connected with PLC 7 with solenoid valve 8.
During use, air compressor 1 produces the pressurized air of high temperature, the pressurized air of high temperature is controlled by PLC 7, partly or entirely enter heat exchanger 5, heat exchanger 5 absorbs the compressed-air actuated heat of high temperature, from heat exchanger 5 pressurized air out with together with solenoid valve 8 pressurized air out, enter air cooler 2 cool, enter cooling driers 3 through the cooled pressurized air of air cooler 2 and carry out cooling de-watering, enter filter set 4 from cooling driers 3 pressurized air out to filter, pressurized air after filtering enters the cryogenic gas entrance of heat exchanger 5, film group 6 entrance is entered after heating, heat needed for heat exchanger 5 heats the pressurized air after filtering for before the heat that absorbs, therefore heat exchanger does not need extra energy ezpenditure, energy-conserving and environment-protective.
The value of PLC 7 monitor temperature sensor 9, if lower than the temperature of setting value, then drive solenoid valve 8 suitably to reduce the aperture of solenoid valve according to pid algorithm, then the flow of the gas of the high temperature compressed air inflow heat exchanger 5 produced by air compressor 1 increases.If the temperature monitored is higher than setting value, just suitably increase the aperture of solenoid valve 8 according to pid algorithm, reduce the flow entering the gas of heat exchanger 5.Thus realize the object accurately controlling heat exchanger outlet gas temperature.
Be understandable that, above about specific descriptions of the present utility model, the technical scheme described by the utility model embodiment is only not limited to for illustration of the utility model, those of ordinary skill in the art is to be understood that, still can modify to the utility model or equivalent replacement, to reach identical technique effect; Needs are used, all within protection domain of the present utility model as long as meet.
