At present, the problems of measuring point faults or pipe wall overtemperature are encountered in the power generation process of a thermal power plant, so that the problems can not be controlled in time, and the leakage of the overtemperature of the water wall of the transition section causes forced shutdown of the unit. The transition section water cooling wall of the thermal power plant does not have measuring points for all pipes, the wall temperature of the pipes cannot be measured during the period that the unit is not stopped, the accuracy of the wall temperature measuring points cannot be checked, when the wall temperature measuring points are abnormal, the pipe wall cannot be controlled in time, and the safe and stable operation of the unit cannot be ensured.
Disclosure of Invention
The utility model aims to provide a drawer device capable of directly measuring the wall temperature of a transition section of a boiler.
The above object is achieved by the following technical scheme:
a drawer device capable of directly measuring the wall temperature of a transition section of a boiler comprises the following components: the drawer storage support is arranged at the upper water-cooled wall, a group of drawer boxes are arranged on the drawer storage support, the drawer boxes are arranged in a rectangular structure, the box body of each drawer box is of a heat-insulating aluminum skin guard plate structure, and the drawer boxes are filled with aluminum silicate refractory fiber blankets, and the front face of each drawer box is connected with a drawer handle.
The drawer device capable of directly measuring the wall temperature of the transition section of the boiler is characterized in that the drawer box is of a hollow structure, the drawer box is closed by a roof, and the side, close to the boiler wall, of the drawer box is of an open structure.
The drawer device capable of directly measuring the wall temperature of the transition section of the boiler is characterized in that the drawer storage support is 30mm by 3mm angle iron.
The utility model has the beneficial effects that:
1. according to the utility model, even under the condition of damage and faults of the wall temperature measuring points, the accuracy of the wall temperature measuring points can be checked, and the wall temperature of each pipe can be easily and accurately measured by using the temperature measuring gun, so that the non-stop probability of the unit is reduced, and the safe and stable operation of the unit is ensured.
2. When the temperature measuring drawer device encounters the problems of measuring point faults or pipe wall overtemperature, the temperature measuring drawer device can be used for further confirmation; the device is simple to manufacture and only uses the heat-preservation outer guard plate; an aluminum silicate refractory fiber blanket; a drawer handle; 30mm by 3mm angle iron.
3. The utility model can directly measure the wall temperature of the pipe during the continuous operation of the unit, can check the accuracy of the wall temperature measuring point, and can timely control the pipe wall not to be over-heated when the wall temperature measuring point is abnormal, thereby ensuring the safe and stable operation of the unit.
4. According to the utility model, during the running of the unit, the water wall heat preservation can not be removed in a large area, and the wall temperature of each pipe can be easily and accurately measured by only opening each drawer and using a temperature measuring gun. After transformation, under the condition that parameters of the wall temperature measuring point are abnormal, the wall temperature and the accuracy of the measuring point are directly judged, and meanwhile, the safe and stable operation of the unit is ensured.
