Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and in particular relates to a condensed water treatment device for a condensing gas water heater and a treatment method thereof. Background Art

[0002] Condensing gas water heaters are widely used due to their energy-saving and environmentally friendly characteristics. They preheat cold water by absorbing the residual heat of the high-temperature flue gas generated by combustion, thereby improving the thermal efficiency of gas water heaters. However, in the process of preheating cold water in the condenser of the condensing gas water heater, the water vapor in the high-temperature flue gas condenses in the condenser to produce a large amount of liquid condensed water. Since the high-temperature flue gas generated by the combustion of natural gas contains a large amount of acidic substances (carbon oxides, sulfur oxides, nitrogen oxides, etc.), which are dissolved in the condensed water, the condensed water is acidic, and the discharge of condensed water is a problem to be solved.

[0003] At present, the existing technology generally adopts the method of condensed water atomization to achieve the purpose of discharging condensed water, wherein the discharge speed of the water mist formed by the condensed water atomization is the key to affecting the discharge of condensed water. The prior art discloses a condensate treatment device for a gas water heater and a water heater device thereof, which uses a built-in fan of the gas water heater or an additional fan to increase the air flow rate in the exhaust pipe. It was later discovered that the built-in fan of the gas water heater is not suitable for practical applications, and it is not feasible to set up an additional fan, which poses a safety hazard. Since the wind speed generated by the fan is related to the combustion state of the combustion chamber and cannot be arbitrarily changed, the oxygen entering the combustion chamber per unit time will increase, affecting the working condition of the gas water heater and the final water outlet temperature; the prior art also discloses a condensate atomization discharge device and a condensing gas water heater, wherein a first row of fans is arranged below a sprinkler, a second row of fans is located directly in front of the first row of fans and is vertically distributed, one end of the atomization discharge pipe is located above the second row of fans, and the other end of the atomization discharge pipe is connected to the exhaust pipe of the condensing gas water heater. If the atomization discharge pipe is set separately, the original layout of the gas water heater needs to be adjusted, which increases the cost and is not conducive to production. At the same time, there is a risk of air leakage, and the sprinkler is arranged below the condenser, which increases the height of the atomization device from the exhaust pipe outlet, which will aggravate the atomization reflux phenomenon and affect the discharge efficiency, which is not practical. Therefore, in view of the above problems and technical requirements, it is necessary to improve the existing condensing gas water heaters. Summary of the invention

[0053] Based on Embodiment 1, the difference in this embodiment is that the exhaust pipe and the flow guiding mechanism are omitted, the condenser pipe serves as the exhaust pipe, the condenser and the smoke exhaust pipe are connected from bottom to top, the air outlet pipe of the auxiliary fan is arranged on the side wall of the condenser pipe, and the rest is the same.

Referring to the following experimental method, under laboratory conditions, only the auxiliary fan and the atomizing mechanism are started, and 967.5 ml of condensed water is discharged per hour on average. Embodiment 15

[0056] Based on Embodiment 1, the difference in this embodiment is that the two-fluid atomizing head is replaced with a pressure atomizing head, and the air pump is replaced with a pressure pump.

[0058] A method for heating cold water and accelerating the treatment of condensed water using the condensing gas water heater of Embodiment 1 is as follows: (1) Tap water enters the heat exchanger through the condenser, and natural gas heats the heat exchanger to heat the cold water, while generating high-temperature flue gas; (2) The high-temperature flue gas enters the condenser under the action of the combustion control fan for preheating the cold water, and the condensed water generated when the water vapor in the high-temperature flue gas meets cold in the condenser enters the water collection chamber; (3) The water level sensor sends a signal to the central control unit, and the central control unit controls the atomizing head to inhale the condensed water, the air pump operates to generate a pressurized air flow, and the condensed water is broken up to form a condensed water water mist; (4) The auxiliary fan is started to form an air flow, which is blown into the exhaust pipe from the air outlet pipe of the auxiliary fan. The air flow passes through the Tesla valve, the wind deflector is blown open, and the air flow drives the water mist into the smoke exhaust pipe to accelerate the discharge of the water mist from the smoke exhaust pipe, realizing the acceleration of the condensed water treatment; (5) A small part of the condensed water and water mist flows backward into the condenser due to gravity, and step (4) is repeated.

[0059] Using the method of the present invention can accelerate the discharge of condensed water without affecting the operation of the condensing gas water heater, unexpectedly reducing the backflow of condensed water and water mist, and significantly improving the atomization efficiency. Comparative Example 1

[0060] On the basis of Example 1, the exhaust mechanism and the diversion mechanism are omitted, the condenser is connected to the smoke exhaust pipe from bottom to top, and the two-fluid atomizing head is arranged in the smoke exhaust pipe, and the rest remains unchanged.

[0061] Under laboratory conditions, equal amounts of condensed water are atomized respectively, only the auxiliary fan and the atomizing mechanism are started, and parallel experiments on condensed water treatment are carried out for Comparative Example 1 and Example 1. The results are shown in Table 1.

[0062] Table 1 Results of Condensed Water Treatment

[0063] It can be seen that under the condition that other conditions are the same, the discharge amount of condensed water and water mist using the exhaust mechanism increases by 104.36%, and the atomization efficiency increases by 126.06%, indicating that the exhaust mechanism of the present invention can reduce the re-condensation of condensed water and water mist in the smoke exhaust pipe. Comparative Example 2

[0064] On the basis of Example 1, the diversion mechanism is omitted, and the rest remains unchanged. The discharge amount of condensed water and water mist is lower than that of Example 1, and there is also a risk of waste gas backflow. Comparative Example 3

[0065] The prior art discloses a device for treating condensed water for a gas water heater and its water heater equipment, which uses a built-in fan for exhausting waste gas, or an additional fan for exhausting waste gas can be set to increase the air flow rate in the exhaust pipe, so as to facilitate the discharge of the atomized condensed water and water mist through the exhaust pipe.

[0066] In the actual application process, it is found that when using the built-in fan for exhausting waste gas of the gas water heater, the discharge speed of condensed water is too low to meet the actual requirements; when an additional fan (with the same performance specifications as Example 1) is set at the connection between the combustion chamber and the condenser, the additional fan will cause an increase in the amount of oxygen entering the combustion chamber per unit time, affecting the working condition of the condensing gas water heater. The speed of discharging waste gas into the condenser per unit time will increase, resulting in a shorter residence time of the waste gas in the condenser, poor effect of preheating cold water by the condenser, and the heat of the waste gas cannot be maximally utilized, affecting the final outlet water temperature.

[0067] Since it is inconvenient to measure the gas velocity during the operation of a condensing gas water heater, when the condensing gas water heater is not heating cold water, only the combustion control fan and the auxiliary fan (extra fan) are started. The intake air velocity inside the condenser of Example 1 is measured to be 8 m / s, and the intake air velocity inside the condenser of Comparative Example 3 is 12 m / s. The following data are obtained through SolidWorks Flow Simulation.

[0068] The gas temperature inside the condenser is set at 200 °C, and the ambient temperature is 20 °C. Table 2 shows the exhaust gas temperature inside the condenser of Example 1, and Table 2 shows the exhaust gas temperature inside the condenser of Comparative Example 3. The GG mentioned in Table 1 and Table 2 refers to the air fluid.

[0069] Table 2 Exhaust Gas Temperature inside the Condenser of Example 1

[0070] Table 3 Exhaust Gas Temperature inside the Condenser of Comparative Example 3

[0071] It can be seen that the high intake air velocity inside the condenser of Comparative Example 3 results in an average increase in the exhaust gas temperature by 4 - 5 °C, indicating that the effect of preheating cold water by the condenser is not good, and the heat of the exhaust gas cannot be utilized maximally. Comparative Example 4

[0072] The prior art discloses a condensate atomization discharge device and a condensing gas water heater. The condensate pipe guides the condensate into the sprinkler. The first exhaust fan is arranged below the sprinkler to atomize the condensate, and the second exhaust fan is used to blow the atomized condensate into the atomization discharge pipe and discharge the atomized condensate along the atomization discharge pipe. One end of the atomization discharge pipe is above the second exhaust fan, and the other end of the atomization discharge pipe is connected to the exhaust pipe of the condensing gas water heater.

[0073] The condensate atomization discharge device is arranged below the condenser and a separate atomization discharge pipeline is set, which will increase the cost. Especially, it is also necessary to re-layout the inside of the gas water heater, the operation is complex, the risk of air leakage is increased, affecting the working condition of the gas water heater, and the sprinkler is connected to the bottom of the condenser, resulting in the phenomenon that large particle impurities block the sprinkler, the atomization effect is not obvious, and at the same time, the sprinkler is far from the exhaust pipe, the backflow phenomenon is aggravated, and the condensate discharge efficiency is extremely low, which is not practical.

[0074] The method for accelerating the treatment of condensed water in the exhaust mechanism disclosed by the present invention does not require the user to frequently pour water or additionally reserve a condensed water drain outlet. By setting up an atomization mechanism, the condensed water is turned into condensed water water mist and discharged. In particular, the present invention creatively sets up an exhaust mechanism between the condenser and the smoke exhaust pipe. On the basis of not changing the original internal structure of the condensing gas water heater and not affecting the normal operation of the condensing gas water heater, the wind speed and air volume in the exhaust pipe and the smoke exhaust pipe are increased, and the discharge efficiency of the condensed water water mist is increased by 104.36% on average; a flow guiding mechanism is provided on the air outlet pipe of the auxiliary fan, so that the air flow in the air outlet pipe of the auxiliary fan flows towards the exhaust pipe and prevents the backflow of waste gas and water mist, accelerating the discharge speed of the waste gas and the condensed water water mist; by setting up a filter, it effectively prevents the atomizing head from being blocked and affecting the atomization and discharge efficiency.

[0075] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
