Purifying, high-pressure gas-supplying and detouring combustion heat exchanger

Abstract

The invention discloses a purifying, high-pressure gas-supplying and detouring combustion heat exchanger. The purifying, high-pressure gas-supplying and detouring combustion heat exchanger comprises a plurality of plate type heat exchange units which are arranged and combined into a combustion cavity for allowing a combustor to place in, and a housing; a plurality of gas flow guide plates are arranged among the plate type heat exchange units; the plate type heat exchange units are arranged in the housing; the combustor comprises a combustion fire barrel extending into the combustion cavity, a fuel gas mixing channel connected to one side of the housing, a pre-mixing fan connected to the fuel gas mixing channel and an air filter element arranged at an air inlet of the fan; and when the pre-mixing fan works, gas flow pressure is generated, so that air enters the fuel gas mixing channel after being sucked through the air filter element and purified. The purifying, high-pressure gas-supplying and detouring combustion heat exchanger has the characteristics of being simple and practical in structure, low in manufacturing and wide in application, and has the advantages of being high in heat exchange rate, capable of effectively preventing scale formation by performing high-pressure purifying on air and mixing the air with fuel gas, more sufficient in combustion, energy-saving and environmentally friendly, free of need to dismount and clean, long in service life and the like. The purifying, high-pressure gas-supplying and detouring combustion heat exchanger is a product with senior technical character, practicability and economical efficiency.

Description

【Technical field】 [0001] The invention relates to a purifying forced-pressure air supply bypass combustion heat exchanger. 【Background technique】 [0002] Existing heat exchangers are used in gas water heaters, wall-hung boilers, etc. as the key components of the core of thermal efficiency, and the existing heat exchangers are generally installed on the heat exchange tank on the burner with coils. There is a fin for the coil to pass through, and there is also a heat exchanger that directly uses water pipes to coil. After a period of time, the heat exchanger needs to be removed and cleaned, which is difficult to clean and requires after-sales professional maintenance personnel to operate; the cause of scale formation is mainly formed after the combustion of air particles, which causes inconvenience to users and high maintenance costs. The existing heat exchanger also has defects such as complicated structure, complicated manufacturing process and high cost. [0003] In orde...

[0002] Existing heat exchangers are used in gas water heaters, wall-hung boilers, etc. as the key components of the core of thermal efficiency, and the existing heat exchangers are generally installed on the heat exchange tank on the burner with coils. There is a fin for the coil to pass through, and there is also a heat exchanger that directly uses water pipes to coil. After a period of time, the heat exchanger needs to be removed and cleaned, which is difficult to clean and requires after-sales professional maintenance personnel to operate; the analysis of the cause of the formation of scale is mainly the formation of air particles after combustion, which causes inconvenience to users and high maintenance costs

Existing heat exchangers still have defects such as complex structure, complex manufacturing process and high cost
