[0028] See Figure 1-6
[0029] Working principle: when in use, the transmission pipe 22 is connected with the exhaust pipe of the ash depot in the power plant, so that the excessive positive pressure or negative pressure in the ash depot can be effectively discharged through the exhaust gas emission detection system to ensure that the ash reservoir can obtain effective stable air pressure and thus achieve effective protection effect, through the cover plate 11 in the top seat 11 can effectively block and dredge the exhaust pipe 21 at the end of the transmission pipe 22 to achieve the effect of opening and closing the exhaust pipe 21, By the mounting cover 3 provided in the exhaust pipe 21, and the mounting ring 31 and the guide ring 32 are provided on both sides of the mounting cover 3, so that the mounting cover 3 can be effectively channeled through the air flow in the exhaust pipe 21 through the fixing ring 31 at the same time as the transmission ring 32, so that the gas can be...

The invention discloses a waste gas emission detection system for a power plant, which includes a top seat, a connecting piece and an installation cover; the invention adopts a fixed cover provided in the exhaust pipe through the installation cover, and a filter layer is arranged in the fixed cover The mesh cover and the filter screen, and the pressure sensor provided in the positioning groove in the installation cover can effectively detect the gravity of the fixed cover through the positioning block, so that the filter screen and the filter layer mesh cover in the fixed cover can carry out the control of the exhaust gas to be discharged. While cleaning and removing dust, it can also effectively achieve the effect of detecting dust and impurity components, so as to realize the filtering and cleaning of the exhaust gas in the middle ash storehouse of the pneumatic ash conveying system to ensure that the exhaust gas is pollution-free, and at the same time, it can also effectively detect exhaust pollution. In order to effectively detect the gas discharged from the ash store, it can also achieve effective dust removal and anti-pollution effects, so as to ensure the effective operation of the ash store and greatly extend its service life.
Description
Technical field [0001] The present invention relates to the technical field of detection system, specifically a power plant exhaust gas emission detection system. Background [0002] Power generation is the use of power generation power devices to convert hydropower, fossil fuel thermal energy, nuclear energy and solar energy, wind energy, geothermal energy, marine energy, etc. into electric energy, and power plants, also known as power stations, are plants that convert various primary energy sources stored in nature into electric energy, of which the waste gas of coal-fired power plants is mainly derived from the flue gas generated by boiler combustion, the exhaust gas of the ash storage in the middle of the gas transmission system and the dusty waste gas produced by the coal yard, as well as the coal dust generated by the coal yard, raw coal crushing and coal transportation. Among them, the exhaust of the middle ash depot of the pneumatic ash transmission system is very easy t...
