Condensation type module boiler exhaust structure and method

Abstract

The invention discloses a condensation type module boiler exhaust structure and method. The structure comprises a smoke collecting pipe, wherein the upper end of the smoke collecting pipe communicateswith a smoke vent pipe through a conical pipe, the smoke vent pipe communicates with all module boiler exhaust ports through a plurality of elbow pipes, pipe ports of all the elbow pipes face upward,cover sheets cover the pipe ports of the elbow pipes, one ends of the cover sheets are hinged to the pipe ports of the elbow pipes, the lower end of the smoke vent pipe communicates with a drainage pipe through a water collecting hood, a first electromagnetic valve is installed on the drainage pipe, a plurality of atomizing nozzles are installed on the smoke collecting pipe, a water inlet pipe communicates with each atomizing nozzle through a water distributor, a second electromagnetic valve is installed on the water inlet pipe, and the first electromagnetic valve and the second electromagnetic valve are connected with a module boiler main controller. According to the structure, condensate water of a module boiler can be treated, so that the condensate water is prevented from corroding pipelines.

Description

technical field [0001] The invention relates to an exhaust structure and method for a condensing modular furnace. Background technique [0002] Modular gas boiler, also known as "gas modular furnace", is a heating equipment composed of several single heating units with the same function. Each single heating unit generally has a combustion system, a smoke exhaust system, a heat exchange system, etc. Its structure is basically the same as that of a wall-hung boiler. A single heating unit is a heating module, so it is called a "gas modular furnace". [0003] The combustion tail gas of the gas-fired modular furnace needs to be condensed through two heat exchanges before being discharged into the smoke collection pipe, and finally discharged from the smoke exhaust pipe. Since the condensed water is acidic, when the modular furnace is shut down, it will be attached to the smoke collection pipe and the smoke exhaust pipe. Acidic condensed water on the pipe will corrode the pipe fo...

[0003] The combustion tail gas of the gas-fired modular furnace needs to be condensed through two heat exchanges before being discharged into the smoke collection pipe, and finally discharged from the smoke exhaust pipe. Since the condensed water is acidic, when the modular furnace is shut down, it will be attached to the smoke collection pipe and the smoke exhaust pipe. Acidic condensed water on the pipe will corrode the pipe for a long time, resulting in damage to the pipe
