Intelligent heating system of heat exchange station

Abstract

The invention discloses an intelligent heating system of a heat exchange station. The intelligent heating system mainly comprises a heat exchanger, a heat exchange circulating pump, a control cabinet and a heating user area, wherein the heat exchanger is connected with a primary water supply pipe and a primary water return pipe respectively, the heat exchanger is also connected with a heating water supply pipe and a heating water return pipe respectively, the heating water supply pipe, the heating water return pipe and the heating user area are connected to form a circulation, a direct connection heating pipe is connected onto the heating water supply pipe and connected with the primary water supply pipe, a direct connection water return pipe is connected onto the primary water return pipe as well and connected with the heating water return pipe, a solenoid valve II is mounted on the direct connection heating pipe, a solenoid valve IV is mounted on the direct connection water return pipe, a heating water replenishing pipe bypasses the solenoid valve IV and is connected with the direct connection water return pipe, and a variable-frequency water replenishing pump and a check valve are mounted on the heating water replenishing pipe. The intelligent heating system has the benefits that the system has a heat exchange heating mode and a direct connection heating mode, the heating safety is improved, the heating effect is guaranteed, energy saving and emission reduction effects are good, the heating cost is low, and the system is flexible to use, convenient to manage and maintain and convenient to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of heat exchange stations, in particular to an intelligent heating system for heat exchange stations. Background technique [0002] Common heat exchange station heating systems include heat exchange unit heating systems and direct-connected heating systems. The heating temperature of the heat exchange unit heating system is controllable and adjustable, and is conducive to automatic unattended control. When the water supply temperature difference of the secondary side is required to be small, for example, when the water supply temperature of the primary side of the heat exchange unit is 50°C-70°C and the water supply temperature of the secondary side is 50°C-60°C, the heat exchange unit is used for heating to cause heat exchange. If the selection of the heater is too large, it will lead to problems such as high equipment investment and large land occupation; the direct connection heating system has the charac...

[0002] Common heat exchange station heating systems include heat exchange unit heating systems and direct-connected heating systems. The heating temperature of the heat exchange unit heating system is controllable and adjustable, and is conducive to automatic unattended control. When the water supply temperature difference on the secondary side is required to be small, for example, when the water supply temperature of the primary side of the heat exchange unit is 50°C to 70°C and the water supply temperature of the secondary side is required to be 50°C to 60°C, the heat exchange unit is used for heating to cause heat exchange. If the selection of the heater is too large, it will lead to problems such as high equipment investment and large land occupation; the direct connection heating system has the characteristics of high heating efficiency and no heat energy loss of the heat exchange unit, but the heating temperature is not easy to control

At present, the heat exchange station heating system on the market often only adopts one of the heat exchange unit or the direct connection unit. The process parameters of the pipe network are not completely consistent with the design parameters. When the heat exchange unit or direct-connected unit is considered separately, it often occurs that the heating is not hot and the user complains due to the inconsistency with the design parameters, and it is inconvenient to rectify later.
