JPS63140874A - Dehumidifier for gas low-pressure compressor - Google Patents

Abstract

PURPOSE:To maintain the cooling temperature constant by utilizing the heat generating unit of a refrigerator in a dehumidifier condensing and separating the moisture contained in the gas. CONSTITUTION:The condensed gas is evaporated by a refrigerator 4 and heat- exchanged with the gas sent through a gas inlet A. A moisture contained in the gas is condensed, and the dried gas is brought into contact with a temperature sensor 5 and sent out through a gas outlet B. A solenoid valve 7 is closed by a signal from the temperature sensor 5 when the temperature of the high- pressure gas is higher than the predetermined temperature, on the contrary the solenoid valve 7 is opened when it is lower. Accordingly, the gas can be cooled at the fixed temperature, and an electric heater or the like is not required.

Description

[Detailed description of the invention] 3-11 Field of industrial application of the invention -111 Air and combustion gas used in powder transportation, food manufacturing, drug manufacturing, precision equipment manufacturing and management, constant temperature and humidity chambers, etc. , in each gas production plant.

Constant temperature and dehumidification of gas.

Conventional technology - 6ε In conventional technology, there is a method of condensing and separating the moisture contained in the gas by cooling the gas using a refrigerator.

A thermostat is used to control the operation and shutdown of the refrigerator according to changes in the conditions of the gas entering the dehumidifier.

In addition, when constant temperature conditions are required, the problem is solved by the invention of lowering the temperature to a lower temperature than the target temperature and then heating it using an electric heater and a steam heater. If the thermostat is used to restart the refrigerator after it has been stopped, for the purpose of filing a lawsuit against the refrigerator, the refrigerator must be restarted for 5 to 3 minutes.
Restart cannot be performed for 0 minutes. Therefore, the temperature of the gas being cooled varies significantly.

In addition, if constant temperature conditions are required, a cold 2V machine with a larger capacity than necessary is required to achieve a lower temperature than the target temperature, and an electric heater and steam heater are required for each length. , This also increases operating costs.

3-21 Means for Solving the Constituent Problems of the Invention -M-Figure, (1) High-temperature, high-pressure gas compressed by the cooling compound machine exchanges heat with outside air by a fan motor in (2) the condenser, and is condensed.

The condensed gas ■passes through the expansion valve, ■evaporates in the cooler, and ■
It evaporates in the cooler and exchanges heat with the gas sent from the gas inlet. At this time, the gas is cooled and the moisture contained in the gas is condensed and discharged from the <C> drain outlet. V, the dry gas from which the moisture has been separated, ■contacts the temperature sensor,
(B) The gas is sent out from the gas outlet.

G) The signal received by the temperature sensor is received by the amplifier, and this signal is given to the solenoid valve.

From this, it can be concluded that the high-temperature, high-pressure gas compressed by the refrigerator is
If the temperature of the gas is higher than the target temperature according to the signal received by the temperature sensor, the solenoid valve will close and the high temperature and high pressure gas will not flow. Conversely, if the gas temperature is lower than the target temperature, the solenoid valve opens.

High-temperature, high-pressure gas flows.

This action cools the gas to a constant temperature.

Examples include pumping flour, cooling molten glass, and constant temperature in ultracentrifuges.

3-30 Effects of the Invention -111 The dehumidifier manufactured with the above configuration can be used as a gas to be cooled between 1°C and 15°C, and as a result, the temperature is increased by +1 to the arbitrarily set value.
At 1.5℃ minus 0.5℃, we were able to perform stable cooling and dehumidification throughout the year6.Also, since the cooling temperature is stable, the effect of the gas used in this device on the product is not ideal. The number of defective products has been significantly reduced because it can be carried out under certain conditions.

Furthermore, there is no need for equipment such as electric heaters and steam heaters as in the conventional system, and operating costs are significantly reduced.
