Problems solved by technology
The condensing heat exchange hot water unit in the prior art, due to the large casing, the water flow in the casing is relatively slow, and the heat transfer efficiency is not high
This kind of problem is not very prominent in small hot water units, but now with the development of large-scale atmospheric pressure condensing heat exchange hot water units, the shell is getting bigger and bigger, and the problem of slow water flow in the shell is becoming more and more prominent, resulting in heat transfer. less efficient
If the flow rate of water in the shell cannot be effectively improved, it will form a great obstacle to the large-scale development of this kind of high-safety, simple-to-operate, and convenient normal-pressure condensing heat-exchanging hot water unit.

The invention provides a condensation heat exchange hot water unit. One end of a smoke guide pipe in a shell is connected to a smoke outlet of a combustor drum. The smoke guide pipe is arranged in a water heat exchange space of the hot water unit and further arranged below a water line to be immersed in the water in use. The other end of the smoke guide pipe extends into a smoke heat exchange space. A water flow speeder is arranged in the water heat exchange space and comprises at least one water baffle. The water baffles are fixedly arranged in the shell and further arranged outside the combustor drum in the water heat exchange space, thus a winding water flow path is formed between hot water outlets formed at the front end and the rear end of the shell. Holes or slots are formed in the water baffles to allow the water or water vapor to pass the water baffles to flow. A smoke condensation heat exchange device is arranged in the smoke heat exchange space and comprises a plurality of smoke baffles and sprayers. The smoke baffles are arranged in the smoke heat exchange space to form a winding path. The sprayers correspond to a smoke outlet and are arranged at intervals among the separated smoke baffles. According to the arrangement, heat efficiency of the condensation heat exchange hot water unit is greatly improved.
Description
technical field [0001] The invention relates to the technical field of a normal-pressure heat-exchanging hot water unit, and in particular provides a condensing heat-exchanging hot water unit. Background technique [0002] In the normal pressure condensing heat exchange hot water unit, the drum of the combustion chamber is arranged in the water heat exchange space at the lower part of the shell, and the water heat exchange space is filled with water when used, and the drum is submerged in the water. Fuel is fed into the drum of the combustor for combustion, and heat is transferred to the water in the shell through the wall of the drum of the combustor, and the hot water is output from the rear end of the water heat exchange space of the shell. Above the water heat exchange space is the flue gas heat exchange space. A smoke outlet is set on the top of the combustion chamber drum, and a smoke outlet is connected to the smoke outlet to pass through the water surface. The smoke ...
