Abstract
The utility model relates to an energy-saving residual heat regeneration dryer. The dryer comprises a PLC controller, a dew point instrument, an adsorption tower, an analysis tower and a pneumatic valve; an electronic electromotive adjusting valve V14 is additionally arranged on the regeneration air pipe of the dryer provided with a regeneration airflow amount manual gate valve V5; and the electronic electromotive adjusting valve V14 is electrically connected with the PLC controller and controlled by the PLC controller. The utility model utilizes the dew point analyzer to carry out the real-time detection of the air dew point of finished products, conveys the analysis data to the PLC controller, and conveys the commands to the electronic electromotive adjusting valve V14 additionally arranged on the regeneration air pipe after the comparison operation is performed according to input signal values by the PLC controller; the received current signals can be converted into corresponding linear displacement through the electronic electromotive adjusting valve; and the opening degree of the electronic electromotive adjusting valve is automatically controlled, so as to realize automatic,continuous, real-time and adjustable regeneration airflow amount.
Description
Technical field
The utility model relates to a kind of drier of nitrogen oxygen device, relates in particular to a kind of energy-saving waste heat regenerative dryer.
Background technology
The user before to the first type selecting of waste heat regeneration drying equipment to the tolerance of equipment certainly factually the border condition put sufficient surplus, moreover the device processes ability is placed with during manufacturing firm's art designs 10～15% surplus, promptly the actual gas consumption of user is much smaller than the specified treating capacity of equipment.Finished product gas dew point is the key index of drying equipment, and the equipment actual working conditions is superior more, and the actual dew point value of finished product gas will be far below design load.Under fixing situation of work period, waste heat regeneration its finished product gas dew point value of drying equipment and being inversely proportional to relation of regeneration gas flow, that is: regeneration gas flow increase, the reduction of finished product gas dew point; The regeneration gas flow reduces, and finished product gas dew point rises.Existing drier is by regulating hand sluice valve (V
5) control regeneration gas flow (as Fig. 1), cause the waste of the energy.
Summary of the invention
The utility model has been mainly and has solved the problems of the technologies described above, and provides a kind of and can regulate the regeneration gas flow automatically, the energy-saving waste heat regenerative dryer of energy savings.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises PLC controller, dew point hygrometer, adsorption tower, Analytic Tower, pneumatic operated valve, add an electronic type electric control valve on the regeneration gas pipeline that is provided with regeneration gas flow hand sluice valve of described drier, the electronic type electric control valve is electrically connected with the PLC controller, controlled by the PLC controller.
The beneficial effects of the utility model are: the utility model detects finished product gas dew point in real time with the dew point analysis instrument, and will analyze data and be delivered to the PLC controller, PLC carries instruction to give the electric control valve that is installed on the regeneration gas pipeline after comparing computing according to input signal values, electric control valve then is transformed into corresponding straight-line displacement with the current signal that receives, the aperture of autocontrol valve is to realize continuous, the Adjustable real-time to the regeneration gas flow.
