[0022] The following is combined with Figure 1 —4 The specific implementation methods of the utility model are further described in detail.

[0023] like Figure 1-4 As shown,

[0024] Example 1, a reflux device for producing an acidic cleaning agent, comprising a reactor 1, a flow rate reducer 2 provided at the upper end of the reactor 1, the flow rate reducer 2 being in communication with the gas outlet of the reactor 1, and the flow rate reducer 2 being a structure for reducing the steam flow rate;

[0025] The outlet end of the flow rate reducer 2 is connected to the air inlet of the condenser, and the air outlet end of the condenser is connected to the reactor 1.

[0026] A one-way valve is installed at the air outlet of the condenser. The setting of the one-way valve prevents the steam of the reactor from flowing out of the air outlet of the condenser.

[0027] In this device, the condenser is an existing technology, which uses a cooling medium to exchange heat with steam, thereby condensing the steam into liquid. Since the condenser is not improved, the condenser is omitted in the drawing.

[0028] The steam in the reactor 1 flows upward into the flow reducer 2, thereby reducing the flow rate of the steam. After the steam enters the condenser, its speed will be greatly reduced. Then the flow rate is reduced and the contact time with the cooling medium is increased, thereby increasing the condensation effect and improving the reflux effect.

[0029] Example 2, based on Example 1, specifically discloses the structure of a flow velocity reducer 2, wherein the flow velocity reducer 2 includes a first pipe 3 and a second pipe 4, the upper end of the first pipe 3 is a blocked structure, and the lower end of the second pipe 4 is a blocked structure, and a plurality of connecting pipes 5 are fixed on the outer circumference of the first pipe 3, and the upper end of the connecting pipe 5 is connected to the second pipe 4.

[0030] In this device, the first pipe 3 is connected to the reactor 1, and the steam enters the first pipe 3 at the first time. The upper end of the first pipe 3 is blocked. At this time, the upward flow of steam is blocked by the upper end of the first pipe 3, which will reduce the flow rate of the steam. Then, the steam with reduced speed enters the second pipe 4 through the connecting pipe 5, and finally inputs steam into the condenser to condense and reflux the steam.

[0031] The upper end of the first pipe 3 is a tapered structure, and the lower end of the connecting pipe 5 is arranged on the outer circumference side of the upper end of the first pipe 3.

[0032] The conical structure is provided with a guide groove on the conical structure, and the guide groove is communicated with the connecting pipe 5, so that steam enters the connecting pipe 5 through the guide groove.

[0033] The lower end of the second pipe 4 is a tapered structure, and the upper end of the connecting pipe 5 is arranged on the outer circumference side of the lower end of the second pipe 4.

[0034] Example 3, based on Example 2, a first reflux pipe 6 is additionally provided, the lower end of the second pipeline 4 is connected to the first reflux pipe 6, the first reflux pipe 6 is connected to the reactor 1, and a first valve 7 is provided on the first reflux pipe 6.

[0035] The lower side of the second pipe 4 is a tapered structure, so even if some steam is condensed in this process, the condensed liquid gathers at the lowermost side of the second pipe 4 and then enters the first reflux pipe 6. The first reflux pipe 6 and the second pipe 4 are made transparent, which makes it easy to observe the actual condensation situation. When it is found that the amount of liquid in the first reflux pipe 6 is large, the first valve 7 is opened to transport the liquid into the reactor 1, and then the first valve 7 is closed.

[0036] Example 4. On the basis of any one of Examples 1-3, a second reflux pipe 8 and a third reflux pipe 9 are additionally provided. At this time, the flow velocity reducer 2 is no longer directly connected to the condenser, but the upper end of the flow velocity reducer 2 is connected to the second reflux pipe 8 and the third reflux pipe 9, a U-shaped tube 10 is provided between the second reflux pipe 8 and the third reflux pipe 9, the lower end of the U-shaped tube 10 is connected to the fourth reflux pipe 11, the fourth reflux pipe 11 is connected to the reactor 1, and a second valve 12 is provided on the fourth reflux pipe.

[0037] The U-shaped tube 10 is mainly provided to prevent a backflow of condensed water. In this way, even if condensate is generated in this process, it will remain in the U-shaped tube 10 and enter the fourth reflux pipe 11 through the U-shaped tube 10. The U-shaped tube 10 and the fourth reflux pipe 11 are also made transparent. In this way, according to the amount of liquid in the fourth reflux pipe 11, the timing of opening the second valve 12 is determined so that this part of the liquid can flow back into the reactor 1.

[0038] In this embodiment, the third return pipe 9 is communicated with the air inlet of the condensed gas. A plurality of baffles 13 are provided in the third return pipe 9 , and two adjacent baffles 13 are arranged opposite to each other.

[0039] like Figure 4As shown, a plurality of baffles 13 are provided on the horizontal portion of the third return pipe 9 , and steam entering is blocked by the baffles 13 , at which point the flow rate is further reduced, thereby improving the final condensation effect.

[0040] The cross-sectional area of ​​the baffle plate 13 is greater than half of the cross-sectional area of ​​the third reflux pipe 9 .

[0041] Two adjacent baffles 13 are intersected with each other, so that the steam can be fully decelerated.

[0042] In this embodiment, during use, the steam from the reactor flows from the reactor to the flow rate reducer 2, then to the second reflux pipe 8, then to the U-shaped tube 10, then to the third reflux pipe 9, then to the condenser, where the condensate finally flows back into the reactor. The steam is decelerated by the flow rate reducer 2 and then by the baffle 13, thereby increasing the steam's flow time in the condenser and improving the condensation effect. The steam then flows through the first reflux pipe 6 and the fourth reflux pipe 11, preventing the partially condensed liquid from hindering the operation of the equipment.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
