Embodiment Construction

[0029] The present invention is described in further detail below in conjunction with embodiment. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the composition related to the present invention, and directions and references (for example, up, down, left, right, etc.) can only Used to aid in the description of features in a drawing. Accordingly, the following Detailed Description is not to be taken in a limiting sense, and the scope of claimed subject matter should be defined only by the appended claims and their equivalents.

[0030] Such as Figure 1 to Figure 5 As shown, a gas water heater exhaust gas utilization device for softening water includes: an intake pipe 1 provided with a gas compression pump 3, a mixing reaction pipe 2 with a built-in spoiler 21, a pH value regulator 4, and a water inlet pipe 5 , static tank 6 and the water storage water supply tank 7...

Abstract

The invention relates to a gas water heater waste gas utilization device for softening water. The device includes an air inlet pipeline connected to a gas water heater waste gas emission pipeline, a mixed reaction pipeline with built-in turbolators, a pH value adjustment apparatus, a water inlet pipe, a standing tank and a water storage and supply tank under the standing tank. Gas water heater waste gas is compressed and then guided into weak alkali water that is treated by the pH value adjustment apparatus in advance and has pH within certain range, then the waste gas and treated weak alkaliwater enter the mixed reaction pipeline, in which CO2 in the waste gas is absorbed by water, and then the waste gas and water enter the standing tank, and in an alkaline environment, reaction with calcium and magnesium substances in water is carried out to generate solid insoluble substances, which are then removed by standing adsorption and other physical means, finally weak alkali softened wateris obtained and introduced into the water storage and supply tank for daily water usage. The device re-utilizes gas water heater waste gas that is rarely recycled for softening hard water, reaches the effects of reducing emission and improving water quality, and has high social value and environmental protection value.

Description

technical field [0001] The invention belongs to the technical field of energy saving and emission reduction, and in particular relates to a gas water heater exhaust gas utilization device for softening water. Background technique [0002] Gas water heaters are the mainstream form of water heaters on the market at present, with an annual output of tens of millions of units, accounting for almost half of the water heater market output, and has developed rapidly in recent years, and its sales growth rate has greatly exceeded other types of water heater products. The gas water heater is ready to use, the water output speed is fast, the water output is large, and the gas price is low. It is a good household hot water product. However, gas water heaters will emit a large amount of CO2 and some SO2 and other gases. Since gas water heaters on the market usually directly discharge this part of gas into the atmosphere, there is almost no use and treatment, which produces a relatively ...
