Computer-controlled exhaust gas concentration monitoring thermal power plant electric equipment

Abstract

The invention discloses a computer-controlled thermal power generation device for monitoring exhaust gas concentration, which includes a boiler body, a heat transfer cylinder is set inside the boiler body, and a pulverized coal feeding port is arranged on the bottom side surface of the heat transfer cylinder. The inner bottom of the heat transfer cylinder is provided with a combustion tank corresponding to the pulverized coal feed inlet, and the inner surface of the combustion tank is fixed with uniformly distributed blowers, and the bottom surface of the boiler body is provided with a waste gas outlet. The waste gas outlet end is connected with a waste gas recovery and purification mechanism, and the bottom liquid outlet of the waste gas recovery and purification mechanism is equipped with a waste water micro metal sorting and collection mechanism, and the outer surface of the boiler body is equipped with sampling and detection mechanisms of different heights. A controller is arranged outside the boiler body, and the connection ends of the controller are respectively electrically connected with the electrical components of the blower, the sampling detection mechanism and the exhaust gas recovery and purification mechanism. The invention has the advantages of simple structure and strong practicability.

Description

technical field [0001] The invention relates to the field of calculation and control equipment, in particular to a computer-controlled electrical equipment for monitoring exhaust gas concentration of a thermal power generation device. Background technique [0002] For a single-channel sampling device, the biggest problem is that the sampling on the grid points at each measuring hole or even all the measuring holes can only be carried out sequentially, and the simultaneous sampling of all grid points cannot be realized, which seriously affects the measurement accuracy. It also brings problems such as heavy workload and inconvenient operation. At the same time, the condensed water is pressed back to the boiler with a high-temperature pump to discharge the steam. If the steam is not discharged, the pressure of the return pipe will greatly reduce the heat transfer effect and affect the production process temperature. and production efficiency, greatly wasting resources and pollu...
