This invention provides a constant temperature and dehumidification system and control method for a grain silo air conditioner, comprising: an air duct and an air outlet for supplying fresh air; a temperature and humidity sensor and an electric air valve are installed at the air outlet, and the airflow at the air outlet is controlled by adjusting the opening of the electric air valve; fluid in the temperature control pipeline is used to exchange heat with the air entering the air outlet; an electronic expansion valve is installed on the refrigeration pipeline of the air conditioner, located between the evaporator and condenser of the air conditioner; a controller is connected to the temperature and humidity sensor and the electric air valve respectively, and the controller controls the opening of the electronic expansion valve according to the signal from the temperature and humidity sensor to adjust the humidity of the grain silo; the controller calculates the required airflow at the air outlet according to the signal transmitted by the temperature and humidity sensor, thereby controlling the opening of the electric air valve to adjust the temperature of the grain silo, thus solving the technical problem of high energy consumption and high cost of grain storage silos in existing constant temperature and dehumidification control methods in related technologies.

This invention relates to the field of coal-to-methanol production equipment technology, and more particularly to a distillation column for separating crude methanol by-products from coal-to-methanol production. The column includes a pre-distillation column, a pressurized distillation column, and an atmospheric distillation column. An energy-saving control device is installed between the pressurized and atmospheric distillation columns. The power control device controls the steam output of the pressurized distillation column, and then valve two controls the liquid phase distribution to the atmospheric distillation column, thereby achieving equilibrium and effectively saving energy. A temperature compensation device is installed between the pressurized distillation column and the reboiler. This device includes a heat storage body installed on pipeline two, with an insulation layer outside the heat storage body. A temperature sensor is installed near the end of the heat storage body. The heat storage body can store heat when the steam flow is high, thus stabilizing the power of the reboiler and providing a buffer time for delayed feedback control, ensuring stable operation of the three columns.
