Specifically, the neutralization apparatus 100 includes a housing 10 and a liquid passing member 20 disposed within the housing 10. The shape of the housing 10 may be a cylinder, a square cylinder or other special-shaped cylinder according to practical needs, and is not particularly limited herein. The liquid passing member 20 is disposed in the housing 10, and a certain space is formed between an inner wall surface of the housing 10 and an outer wall surface of the liquid passing member 20, so that a neutralization cavity 102 is formed in the housing 10 corresponding to an outer peripheral area of the liquid passing member 20. The neutralizing agent may be solid or liquid, for example, alkaline neutralizing particles may be placed in the neutralizing chamber 102. The housing 10 is provided with a liquid inlet 101 communicating with the neutralization chamber 102, the liquid inlet 101 being for connection with an external pipe. For example, when the neutralization apparatus 100 is applied to a condensing gas water heater, the liquid inlet 101 may be in communication with a condensate outlet of the condensing gas water heater, so that acid condensate generated by the condensing gas water heater may enter the neutralization chamber 102 through the liquid inlet 101, and then be in sufficient contact with the neutralizing agent to perform a neutralization reaction, so that the acid condensate is neutralized into a neutral liquid.

The liquid passing member 20 is provided with a tortuous liquid flow channel 201, that is, the liquid flow channel 201 integrally presents a non-linear flow path from the liquid inlet end to the liquid outlet end, for example, the liquid flow channel 201 may be designed as a U-shaped channel, an S-shaped channel, a spiral-shaped channel, or the like, which is not particularly limited herein. The liquid inlet end of the liquid flow channel 201 is communicated with the neutralization cavity 102, and the liquid outlet end of the liquid flow channel 201 penetrates through the shell 10, so that the neutralized neutral liquid in the neutralization cavity 102 can enter the liquid flow channel 201 and is finally discharged out of the shell 10 from the liquid outlet end of the liquid flow channel 201. The flow channel 201 is in a tortuous arrangement, so that the length of the flow channel 201 can be prolonged in a limited space, and meanwhile, the resistance of the flow channel 201 can be increased, so that the acid condensate water can be discharged after fully reacting with the neutralizing agent in the neutralizing cavity 102, and the acid condensate water can be completely neutralized into neutral liquid.

When the neutralization device 100 is applied to condensing gas equipment, acidic condensed water generated by the condensing gas equipment can enter the neutralization cavity 102 through the liquid inlet 101, and then is fully contacted with a neutralizing agent to perform neutralization reaction so as to neutralize the acidic condensed water into neutral liquid; neutral liquid enters the liquid flow channel 201 and is finally discharged out of the housing 10 from the liquid outlet end of the liquid flow channel 201. The tortuous arrangement of the flow channel 201 can extend the length of the flow channel 201 in a limited space while increasing the resistance of the flow channel 201 to allow the acid condensate to fully react with the neutralizing agent in the neutralizing chamber 102 and then drain out to ensure that the acid condensate can be fully neutralized to neutral. Therefore, the acidic condensate water can be effectively neutralized so as to meet the discharge requirement and avoid corrosion to a discharge pipeline.

An annular liquid inlet passage 2011 is formed between the inner peripheral surface of the sleeve 22 and the outer peripheral surface of the liquid outlet pipe 21, and the liquid inlet passage 2011 has a liquid passing port 223 communicating with the neutralization chamber 102, wherein the liquid passing port 223 may be formed on the end surface of the sleeve 22 or may be formed on the peripheral surface of the sleeve 22. For example, in the present embodiment, the sleeve 22 and the liquid outlet tube 21 are both disposed along the vertical extension, the bottom of the sleeve 22 is disposed in an open manner, and an annular liquid passing port 223 is formed between the bottom open end 222 of the sleeve 22 and the liquid outlet tube 21. The bottom end of the liquid outlet pipe 21 penetrates through the bottom wall (i.e., the first end wall 111) of the housing 10, and a liquid outlet 2111 is formed in the bottom end of the liquid outlet pipe 21. In this way, the neutral liquid after neutralization in the neutralization chamber 102 enters the liquid inlet channel 2011 through the liquid passing port 223, and is discharged to the outside of the casing 10 through the liquid outlet port 2111 of the liquid outlet channel 2012; the entire flow channel 201 is simple in construction and easy to manufacture.

In particular, in practical use, the neutralization apparatus 100 is generally preferably connected to the piping system in a vertically disposed condition, and accordingly, the sleeve 22 and the liquid outlet pipe 21 are each disposed to extend vertically. The top end of the sleeve 22 is a closed end 221, the bottom end of the sleeve 22 is an open end 222, an annular liquid passing port 223 is defined between the inner edge of the open end 222 and the outer circumferential surface of the liquid outlet pipe 21, and the open end 222 of the sleeve 22 is suspended relative to the bottom wall (i.e. the first end wall 111) of the casing 10, so that the neutralization cavity 102 is communicated with the liquid passing port 223. The liquid outlet pipe 21 comprises a first pipe section 211 extending vertically, the top end of the first pipe section 211 is connected with the closed end 221 of the sleeve 22, a first overflow port 2112 is arranged on the top peripheral wall of the first pipe section 211, one end, far away from the liquid passing port 223, of the liquid inlet channel 2011 is communicated with the liquid outlet channel 2012 through the first overflow port 2112, and a liquid outlet 2111 is formed at the bottom end of the first pipe section 211. In this way, the neutral liquid in the neutralization chamber 102 enters the liquid inlet channel 2011 through the liquid passing port 223 at the bottom of the sleeve 22, and when the liquid level of the neutral liquid reaches the height of the first overflow port 2112, the neutral liquid enters the liquid outlet channel 2012 of the first pipe section 211 through the first overflow port 2112 and rapidly flows downwards to the liquid outlet port 2111 to be discharged under the action of gravity. Thus, the neutral liquid can stay in the liquid inlet channel 2011 for a period of time to ensure complete reaction with the neutralizer and meet the discharge requirement; when neutral liquid enters the liquid outlet channel 2012, the neutral liquid can be rapidly discharged under the self gravity without adding other power devices, so that the structure can be simplified, and the cost can be saved.

As shown in fig. 4, in one embodiment, the first overflow port 2112 includes a plurality of first overflow grooves arranged at intervals along the circumferential direction of the first pipe section 211, and each of the first overflow grooves is disposed along the axial direction of the first pipe section 211.
