Embodiment 1

[0081]The project is located on North Fourth Ring West Road, Haidian District, Beijing, with a construction area of ​​25,000 m2. The building is a multi-storey brick-concrete structure, with the highest number of floors being 4 floors.

[0082] (1) The original heating system

[0083] The unit originally had two 4t atmospheric pressure hot water coal-fired boilers, each with a heat supply of 2.8×Mw, one for use and one for standby (the two atmospheric pressure boilers have been in service for a long time and are close to being eliminated), and 2 circulation pumps ( The flow rate is 100m 3 / h, lift is 32m, power is 15kw), one for use and one for standby.

[0084] The terminal equipment of the original heating system of the dry rest center all adopts radiators (four-column 813 radiators). The maximum supply water temperature of the original heating system is 80°C, and the maximum return water temperature is 60°C. The heating system is in the form of double-pipe vertical parall...

Abstract

The invention discloses a design method of a geothermal engineering automatic monitoring system. The design method of the geothermal engineering automatic monitoring system comprises the following steps: S1, analyzing controlled geothermal engineering system operation; S2, selecting a controlled parameter and a control parameter; S3, selecting and measuring a transformation unit and an execution mechanism; S4, selecting a control scheme and a control rule; and S5, selecting a system correction method. The advantages are as follows: the operation cost is low, the energy conservation and environmental protection effects are good, and energy consumption parameters indicate that though a boiler system is small in power consumption, primary energy consumption is large. Therefore, the energy efficiency is low, and the environmental protection benefits are poor. Hoverer, a geothermal system is much better, and the environmental adverse effect of the geothermal system is less than the boil system by at last two thirds.

Description

technical field [0001] The invention specifically relates to a design method of an automatic monitoring system for geothermal engineering. Background technique [0002] Sustainable utilization is an important research topic in the development and utilization of geothermal resources. Through the monitoring of dynamic parameters such as water temperature, flow rate, wellhead pressure, and water level of geothermal wells, the exploitation and supply of resources can be kept at a balance. [65] Therefore, in the past, the automatic monitoring system of geothermal information focused on the realization of intelligent management, such as the balance of regional procurement and replenishment and the provision of information and charging basis. It is precisely because of the above reasons that the automatic monitoring and intelligent management of geothermal projects in the past focused on monitoring the relevant information of geothermal wells and reinjection wells, and user informa...
