Abstract
The utility model discloses a heat source system device adjustable in steam parameters. The device structurally comprises a pressure control valve, two dryness testers, a desuperheater, a humidifier, and a desiccant wheel, which are arranged on a steam pipeline. A first cooling water replenishing pipeline is connected to the desuperheater through the temperature control valve. A second cooling water replenishing pipeline is connected to the humidifier through an electric valve. The pressure and the temperature are controlled through respective controllers. The controllers, the first and second dryness testers, the humidifier, the desiccant wheel, and the electric valve are all provided with control lines connected to a control board and are all controllable by the control board. Parameters outputted by the second dryness tester are taken as feedback signals. The control board is used to sample, calculate, and repeatedly adjust all the connected parts to finally enable the temperature, pressure, flow, and dryness of steam outputted by the pipeline to meet design parameters. The testing system is simple, but is capable of effectively ensuring the quality of the steam from various sources. According to the utility model, the problem of great deviation of testing results due to unstable dryness is particularly solved.
