Embodiment 1
[0060] A high-temperature flue gas temperature control system for a flue gas desulfurization project based on the "basic technical scheme" and a method for controlling the temperature of high-temperature flue gas.
[0061] As shown in Figure 2: the high-temperature flue gas temperature control system of the flue gas desulfurization project includes a water spray device I, a flue gas temperature and spray water pressure monitoring device II and a control device III;
[0062] The water spray device I installed in the flue behind the bypass baffle of the desulfurization island is composed of an external water source / water supply pipe 1, a ring water supply pipe 2 for the water spray device, 2 electric control valves 3 for the spray layer and electric regulation for the spray layer Valve actuator 4, 8 spray layer mist water nozzles 5; 2 spare spray layer electric regulating valves 7 and their actuators 8, 8 spare spray layer mist water nozzles 9, outlet pipe 10, outlet pipe Compos...
Embodiment 2
[0103] A high-temperature flue gas desulfurization project based on the "simplified technical solution" A temperature control system and a method for controlling the temperature of high-temperature flue gas.
[0104] The "simplified technical solution" of the second embodiment is different from the "basic technical solution" of the first embodiment in that: the "simplified technical solution" does not have a temperature sensor and a pressure sensor; the electric control valve is changed to an electric valve.
[0105] As shown in Figure 3: the high-temperature flue gas temperature control system of the flue gas desulfurization project of this "simplified technical solution" includes water spraying device I A and control gear III A .
[0106] The water spray device I A The setting principle is the same as that of the water spray device in the "basic technical plan", but the spray layer electric regulating valve and its actuator of the "basic technical plan" use the spray lay...
