Unattended central heat supply monitoring station

Abstract

The invention relates to an unattended central heat supply monitoring station. The station is characterized by mainly comprising a plate heat exchanger, a variable frequency water replenishing pump, a circulating pump, an electric adjusting valve, a ball valve, a controller and a control cabinet, wherein an inlet and a return port of the plate heat exchanger are connected with a primary heat supply pipeline and a primary water return pipeline respectively; the electric adjusting valve is arranged between the primary heat supply pipeline and the plate heat exchanger; a water outlet and a water return port of the plate heat exchanger are connected with a secondary heat supply pipeline and a secondary water return pipeline respectively; the controller is connected with an outdoor temperature sensor, a temperature sensor and a pressure sensor; and the temperature sensor and the pressure sensor are connected with the primary heat supply pipeline and the secondary heat supply pipeline respectively. The unattended central heat supply monitoring station has the advantage of realizing remote transmission and remote control by using a fully automatic unattended operating mode. The system has over-temperature, over-voltage and under-voltage chain protection and alarm function; and through the controller, the temperature of the water supplied by the pipe network can be adjusted according to the outdoor temperature variation so as to ensure the indoor heat supply temperature.

Description

technical field [0001] The invention belongs to a central heating system, in particular to an unattended central heating monitoring station. Background technique [0002] In the north of my country, it has the advantages of reducing coal consumption and reducing CO 2 District heating with emission advantages is widely used. The current heating network is to divide a large-area heating area into several heating districts, and the entire system is monitored through a centralized heating monitoring system between each district and the heating boiler room. Each district establishes a heating station to monitor the heat supply corresponding to the heating district. Setting up several heating stations between the heating networks will cause a waste of personnel, and the human factors that are difficult to manage due to the absence of duty personnel will directly affect the quality of heating supply, and even accidents will occur. At the same time, due to the large range of temp...

Problems solved by technology

Setting up several heating stations between the heating networks will cause a waste of personnel, and the human factors that are difficult to manage due to the unmanageable human factors of the on-duty personnel leaving their duties without permission will directly affect the quality of heating supply, and even accidents will occur

At the same time, due to the large range of temperature changes in winter, the outdoor temperature rises or falls, and the temperature of the hot water supply in the pipe network remains unchanged. The temperature difference between the city and the outside cannot be adjusted, resulting in waste of energy.
