Detailed Description

The technical solution of the present application will be described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, a flue gas purifier disclosed in the embodiment of the present application is mainly composed of a housing 11, a water storage area 12, a filter screen 13, an air inlet pipe 14, a secondary treatment area 15, a heater 16, an exhaust pipe 17, and the like, where the housing 11 is a hollow structure, that is, a cavity is present in the housing 11, and a water storage area 12 is disposed in the cavity, and the water storage area 12 is used for storing a certain water source, so that part of large-volume ashes in exhaust gas flowing into the cavity will first contact with the water surface and then sink to the bottom of the water.

The air inlet pipe 14 is used to connect the plant combustion furnace to the housing 11, and has one end located outside the housing 11 and the other end extending into the interior of the housing 11 and located above the water storage region 12. The filter screen 13 is installed inside the housing 11 and above the water storage area 12, and functions to intercept ash in the exhaust gas.

Meanwhile, the end of the air inlet pipe 14 located in the housing 11 also passes through the filter screen 13, so that after the filter screen 13 intercepts ash in the exhaust gas, the intercepted ash falls into the water storage area 12 below.

Still set up a secondary treatment district 15 in the casing 11, secondary treatment district 15 and casing 11 intercommunication, the effect is handled the tail gas through filter screen 13, and specific processing mode provides a high temperature environment, makes the carbon monoxide in the tail gas can react with oxygen, generates carbon dioxide.

Specifically, a heater 16 is installed in the secondary treatment area 15, and after the heater 16 is powered on, the electric energy can be converted into heat energy, so that the temperature in the secondary treatment area 15 is increased, and carbon monoxide can react with oxygen to generate carbon dioxide in a high-temperature environment.

An exhaust pipe 17 is arranged on the shell 11 and communicated with the secondary treatment area 15, and the tail gas of the plant combustion furnace is filtered and secondarily combusted, and then is exhausted from the exhaust pipe 17.

On the whole, through the mode of filtration and postcombustion, can effectively get rid of ashes and carbon monoxide in the tail gas of plant combustion furnace, reduce the influence of tail gas to the surrounding environment.

As a concrete implementation mode of the smoke purifier provided by the application, the number of the filter screens 13 is increased to two or more, and the plurality of filter screens 13 simultaneously filter ashes in tail gas of the plant combustion furnace, so that the filtering effect is better.

Further, in the direction away from the water storage area 12, the pore size of the filter screen 13 tends to decrease, that is, in the flow direction of the exhaust gas, the pore size of the filter screen 13 is smaller and smaller, on one hand, this filtering manner can reduce the possibility of blocking the filter screen 13, and on the other hand, the ash intercepted by the filter screen 13 is not easy to block the filter screen 13 below the filter screen in the falling process.

As a specific embodiment of the exhaust gas purifier provided by the application, the heater 16 is composed of a heating body 161 arranged in the heating chamber 15 and an electromagnetic heater 162 arranged on the heating body 161, after the electromagnetic heater 162 is electrified, the electric energy is converted into electromagnetic energy, then countless small eddy currents are generated in the heating body 161, so that the heating body 161 self generates heat at high speed, and the purpose of temperature rise is achieved.

This heating method has a high heating speed, and can rapidly raise the temperature of the heating body 161 to rapidly burn carbon monoxide, and can maintain the temperature in the heating chamber 15 constant during continuous heating, thereby contributing to reduction of instability of the carbon monoxide removal effect due to temperature fluctuation.

Further, the electromagnetic heater 162 is placed inside the heating body 161, and the electromagnetic heater 162 is isolated from the space inside the heating chamber 15 by the heating body 161, which contributes to prolonging the service life of the electromagnetic heater 162.

In one embodiment of the exhaust gas purifying apparatus according to the present application, a catalyst plate 21 is attached to the heating chamber 15, and the catalyst plate 21 is positioned in front of the heater 16 in the gas flow direction in the heating chamber 15.

The catalytic plate 21 serves to reduce the condition of carbon monoxide to carbon dioxide, and it is understood that the reaction of carbon monoxide with oxygen to form carbon dioxide needs to be carried out under certain temperature conditions, and the addition of the catalytic plate 21 can reduce the temperature conditions, which contributes to further improving the efficiency of carbon monoxide treatment.

Further, the catalyst plate 21 includes a copper-based catalyst plate and an aluminum-based catalyst plate.

The embodiment of the application also discloses a plant combustion furnace, which comprises the smoke purifier.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
