[0027] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0028] The utility model is further described below in conjunction with the accompanying drawings.

[0029] like Figure 1 As shown in the figure, a condenser for a boiler includes a main body 1, the main body 1 is a rectangular parallelepiped with a hollow interior, an opening is provided on a side wall of one end of the main body 1, a smoke inlet 5 is provided at the opening, a smoke exhaust pipe 12 is provided at the upper end of the main body 1, and the smoke exhaust pipe 12 is connected to the main body 1;

[0030] The bottom of the main body 1 is in an inclined state, and a drainage pipe 11 is provided at the center of the bottom of the main body 1. The drainage pipe 11 is connected to the inside of the main body 1. A plurality of water guide grooves 13 are provided on the bottom wall inside the main body 1. The water guide grooves 13 are evenly and equidistantly arranged. The drainage pipe 11 is made of a stainless steel pipe.

[0031] A condensation device 6 is also provided inside the main body 1, and the condensation device 6 is used for cooling the flue gas.

[0032] The condensation device 6 includes a water inlet 3, a water outlet 4, a water inlet pipe 63, a water outlet pipe 64, a condensation pipe 62 and a mounting bracket 61;

[0033] The condenser 62 is arranged inside the main body 1. The condenser 62 is a coil connected end to end. The head end of the condenser 62 is connected to the water inlet pipe 63, and the tail end of the condenser 62 is connected to the water outlet pipe 64. The mounting bracket 61 is fixed on the condenser 62. The condenser 62 is arranged into multiple coils connected end to end, which increases the stroke of water flow and improves the heat dissipation effect.

[0034] The water inlet 3 and the water outlet 4 are respectively fixed on the front side of the main body 1 . The water inlet 3 and the water outlet 4 extend into the main body 1 and are respectively connected to the water inlet pipe 63 and the water outlet pipe 64 .

[0035] The condenser tube 62 is provided with a plurality of heat dissipation fins 7 , which are evenly and equidistantly arranged. The heat dissipation fins 7 increase the contact area with the air, thereby greatly improving the heat dissipation effect of the condenser.

[0036] A filter tank 2 is also provided at the upper end of the smoke exhaust pipe 12, and a filter element is provided inside the filter tank 2. The filter element includes a filter screen 22 and activated carbon 21. The filter screen 22 is symmetrically arranged at the upper and lower ends of the activated carbon 21. The filter tank 2 can filter out impurities in the smoke. The filter screen 22 filters out large particles of solid impurities, and the activated carbon 21 adsorbs harmful substances inside it, ensuring that the exhausted smoke does not pollute the environment and effectively protects the environment.

[0037] The smoke inlet 5 is provided with a smoke inlet cover for smoke to enter, and the smoke inlet cover is fixed on the side wall of the smoke inlet 5 .

[0038] The working principle of the utility model is as follows: when in use, high-temperature flue gas enters the interior of the main body 1 from the smoke inlet hood of the smoke inlet 5, and when it contacts the condensing device 6, the heat dissipation fins 7 and the condensing tube 62 of the condensing device 6 cool it down. After the cooling of the condensing device 6, the flue gas contains a large amount of high-temperature water vapor, so it will produce a condensation reaction with the condensing device 6, and the water vapor will change from gaseous state to liquid state;

[0039] The condensed water drops on the bottom of the main body 1. Since the bottom of the main body 1 is in an inclined state and is covered with water guide grooves 13, the condensed water flows along the water guide grooves 13 to the bottom of the main body 1 and is finally discharged from the drain pipe 11.

[0040] After condensation and cooling, the flue gas is finally discharged from the exhaust pipe 12, and the filter tank 2 on the exhaust pipe 12 performs the final filtration on the flue gas. The filter screen 22 filters out large particles of impurities, and the activated carbon 21 absorbs harmful substances to ensure the environmental protection of the exhaust gas, thereby protecting the environment.

[0041] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
