Description
Technical Field
The utility model relates to a gas heater technical field, more specifically relates to a gas heater jet-propelled pipe.
Background
People have increasingly strengthened awareness of protecting the environment, the combustion of a gas water heater inevitably generates waste gas, and harmful gases in the waste gas mainly comprise CO and NOXThe primary reason for the generation of these harmful gases is the amount of primary air entering the burner, whether the gas in the burner can be completely combusted as much as possible. The structure of the burner assembly determines the amount of primary air entering the burner, and the gas lance is one of the main components of the burner assembly and plays a crucial role.
In the existing gas water heater, the gas injection pipe is usually only provided with one row of nozzles, relatively speaking, the number of the nozzles is small, so that the amount of primary air injected into a combustor when the nozzles inject gas is small, and harmful gases (CO and NO) after the gas is combustedX) More will be produced, which is not beneficial to environmental protection.
In addition, the gas injection pipe of the existing gas water heater is of a structure which is sealed by a cover plate, on one hand, the hidden danger of leakage exists in sealing, on the other hand, the structure is complex, and the cost is high.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome the gas water heater gas combustion inadequately, harmful gas (CO, NO) after the gas combustionX) More defects, provides a gas water heater gas ejector pipe. The utility model discloses simple structure, convenient to use draws when can improve the jet stack and draws when spraying the gas and penetrate the primary air volume that gets into the combustor, and then reduces the harmful gas (CO, NO) after the gas combustionX) The amount of production of (c).
In order to solve the technical problem, the utility model discloses a technical scheme is: the utility model provides a gas heater gas ejector, wherein, including the gas ejector main part, the inside at least a set of gas channel group that divides that is equipped with of gas ejector main part, each group divides gas channel group to include the branch gas channel of two at least mutual intercommunications, all be equipped with on each branch gas channel ifThe gas injection pipe main body is also provided with a gas inlet channel, and when the number of the gas distribution channel groups is 1, the gas inlet channel is directly communicated with the gas distribution channel groups; when the number of the gas distribution channel groups is more than 1, the gas distribution channel groups are independent from each other, and the gas inlet channel is directly communicated with one of the gas distribution channel groups and is communicated with the rest gas distribution channel groups through stop valves. In this way, whether only one gas distribution channel group or a plurality of mutually independent gas distribution channel groups are provided, each gas distribution channel group comprises at least two gas distribution channels which are communicated with each other, and each gas distribution channel is provided with a plurality of nozzles, that is, at least two rows of nozzles are provided on the gas ejector pipe body. At this time, the same amount of gas is injected into the combustor through the two rows of nozzles, compared with the same amount of gas injected into the combustor through the one row of nozzles, the number of nozzles is large, that is, the gas is injected with more contact points with the air around the gas nozzle body; the primary air quantity injected into the combustor when each nozzle injects fuel gas is almost limited, so that the more the nozzles are, the more the primary air quantity injected into the combustor when the whole gas injection pipe injects fuel gas is, more air is provided, the more the fuel gas is completely combusted, and the generated harmful gases (CO and NO) are generatedX) Less will be produced, which is beneficial to environmental protection.
