Embodiment Construction
[0030] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0031] Such as Figure 1 to Figure 3 As shown, the present invention provides a flue gas condensation purifier, which includes an inner tube 1, a central tube 2 and an outer tube 3 arranged in sequence from inside to outside, wherein:
[0032] The inner pipe 1 is used to provide a passage for flue gas flow, a cooling passage is formed between the inner pipe 1 and the central pipe 2, and a waste water passage is formed between the central pipe 2 and the outer pipe 3; The groove 11 and the convex groove 11 are penetrated in the cooling channel, and the inner pipe 1 communicates with the waste water channel through the convex groove 11 . The present invention condenses the flue gas by making the flue gas flow in the inner pipe, and the dust in the flue gas will also adhere to the inner wall of the inn...

The invention belongs to the technical field of thermal power generation and discloses a flue gas condensation purifier and a flue gas condensation purification system. The flue gas condensation purifier comprises an inner pipe, a central pipe and an outer pipe, which are arranged in sequence from inside to outside, wherein the inner pipe is used for providing a channel for flue gas to flow; a cooling channel is formed between the inner pipe and the central pipe; a wastewater channel is formed between the central pipe and the outer pipe; a plurality of convex grooves are formed in the peripheral direction of a pipe body of the inner pipe; the convex grooves penetrate into the cooling channel; the inner pipe is communicated with the wastewater channel through the convex grooves. According to the flue gas condensation purifier disclosed by the invention, the flue gas flows in the inner pipe and the flue gas is condensed by utilizing the cooling channel; dust in the flue gas is also attached on an inner wall of the inner pipe due to turbulent flow, and then wastewater and dust which are generated through condensation are commonly discharged into the wastewater channel through the convex grooves formed in the pipe body of the inner pipe and then are discharged to the outside, so that the moisture content and dust content in the flue gas are reduced.
Description
technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a flue gas condensation purifier and a condensation purification system. Background technique [0002] At present, desulfurization devices are generally installed in thermal power plants in my country, most of which are wet limestone-gypsum desulfurization devices. For flue gas systems that are not equipped with a rotary GGH (Gas Gas Heater, gas-to-gas heat exchanger), since the flue gas discharged from the chimney after FGD (Flue Gas Desulphurization, desulfurization tower) is in a saturated state, when the ambient temperature is low Condensation forms a white "wet plume". [0003] At present, the treatment method for "wet smoke plume" mainly adopts the technical scheme of direct heating of flue gas or first condensation and then heating. Due to the high moisture content in the flue gas at the outlet of the desulfurization tower, the direct heating method cons...
