Abstract

The invention relates to a smoke temperature difference power generation smoke pipe device of a gas water heater. The device comprises an internal enhanced heat exchange smoke pipe, a cylindrical temperature difference power generation piece, a cylindrical cold water cooler, a water tank enhanced heat exchange rib and a smoke pipe enhanced heat exchange rib. The smoke temperature difference power generation smoke pipe device is combined with an exhaust pipe of a water heater, can be applied to a new product, and also can be used for transforming a traditional gas water heater. The smoke temperature difference power generation smoke pipe device, provided by the invention, can recover heat energy in smoke for heating inlet water, and can use a temperature difference between the smoke and the inlet water for generating electricity, so that the heat efficiency of the gas water heater is improved, and the operation cost is saved.

Description

technical field [0001] The invention relates to the field of temperature difference power generation combined with gas flue gas waste heat recovery and utilization, in particular to a smoke tube device for gas water heater flue temperature difference power generation. Background technique [0002] With the increasingly serious energy and environmental problems, how to maximize the efficiency of energy utilization on the premise of ensuring environmental friendliness has become a common concern of all countries in the world. In the existing energy system, nearly 70% of the energy is dissipated into the atmosphere in the form of waste heat or waste heat, causing serious energy waste. If this part of energy can be utilized, there will be a very large room for energy saving. According to statistics, the use of gas water heaters in the country has exceeded 70 million units, and the annual output of the industry has reached more than 20 million units. And in recent years, with th...
