Description

Technical Field

[0001] The utility model belongs to the technical field of power generation boilers, and particularly relates to an intelligent detection device for power generation boilers. Background Technique

[0002] Generally speaking, a power generation boiler is a boiler used by a power plant to generate electricity. During the operation of a power generation boiler, a fuel - coal block is required. During the combustion of the coal block, a large amount of tail gas is generated. To improve the environmental protection effect, it is necessary to control the tail gas detection device of the power plant boiler to detect the tail gas generated during the operation of the power generation boiler and determine whether the tail gas meets the emission standards.

[0003] After retrieval, a tail gas detection device for a power plant boiler is disclosed in the patent document with the patent publication number CN216208938U. The tail gas detection device for the power plant boiler includes a device body, and an intake pipe is vertically installed on the top of the device body. The provided tail gas detection device for the power plant boiler facilitates the sampling of boiler tail gas through the coordinated use of the intake pipe, the distribution pipe, the first exhaust hose, the gas collection bag, the second exhaust hose, the first solenoid valve, the second solenoid valve, and the third solenoid valve. When sampling, the intake pipe is connected to the external exhaust pipe, and then the first solenoid valve and the second solenoid valve are opened, so that the tail gas first enters the intake pipe, and then enters the distribution pipe through the intake pipe. Then, under the action of the distribution pipe, it enters each gas collection bag. After the gas collection bag is filled, the second solenoid valve and the first solenoid valve are closed to stop sampling, thus completing the collection of the tail gas. This method is simple to operate and greatly improves the sampling efficiency.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. During the use of the tail gas detection device for the power plant boiler, the worker needs to operate the exhaust mechanism and the third solenoid valve multiple times to introduce the waste gas in different gas collection bags into the detection box, so that the detection mechanism can detect the waste gas in different gas collection bags, avoiding the contingency and omission of waste gas detection, which is beneficial to improving the quality of waste gas detection, but it will increase the labor intensity of the worker and increase the fatigue degree of the worker.

[0006] 2. During the use of the tail gas detection device for the power plant boiler, by operating the exhaust mechanism to introduce the waste gas in the gas collection bag into the detection box, it is convenient for the detection mechanism to detect the waste gas in the detection box. However, due to the single structure of the exhaust mechanism, it is not convenient for the worker to know the amount of waste gas entering the detection box, and it is not convenient for the worker to calculate the content of each component in the waste gas later, which brings inconvenience to the worker to judge whether the waste gas meets the emission standards.

It is convenient for the worker to control the pumping pump 41 to introduce the waste gas inside different waste gas sampling cylinders 42 into the detection box 3 for detection, which is beneficial to reducing the working intensity of the worker and effectively reducing the fatigue degree of the worker during work;

[0027] As shown in Figure 1 , self-locking universal wheels 11 are connected to the four corners of the lower part of a cabinet body 1 connected to the lower part of the horizontal plate 2, which is convenient for adjusting the position of the horizontal plate 2 and the position of the intelligent detection device for the power generation boiler;

[0029] An installation vertical plate 7 is connected to the rear side above the horizontal plate 2. The rear side wall of a first ear seat 423 fixedly connected to the rear side wall of the waste gas sampling cylinder 42 is connected to the front side wall of the installation vertical plate 7, effectively improving the stability of the waste gas sampling cylinder 42 after installation; A horizontal air inlet pipe 6 is arranged above the screw cap 424 threadedly connected to the waste gas sampling cylinder 42. One end of the air inlet pipe 6 is connected with a filter plate 62. The end of the air inlet pipe 6 away from the filter plate 62 is of a closed structure.
