Description

Technical Field

[0001] The utility model relates to the technical field of yellow phosphorus tail gas conveying pipeline components, in particular to a yellow phosphorus tail gas multi-stage washing pipeline component. Background Art

[0002] During the period between combustion and de-whitening of yellow phosphorus tail gas, the tail gas is usually transported to corresponding treatment equipment through pipelines for treatment. However, due to the low temperature of the pipeline, impurities in the tail gas are prone to adhere to the inner wall of the pipeline after long-term tail gas transportation. The adhesion of impurities will not only damage the pipeline, but also affect the normal transportation of the subsequent yellow phosphorus tail gas.

[0003] The traditional method for cleaning impurities from the inner walls of pipes is to disassemble the pipes before cleaning them. This is a relatively cumbersome and labor-intensive operation, especially for long pipes, which are difficult to disassemble and clean, causing inconvenience to the user. In light of this, we have proposed a multi-stage yellow phosphorus tail gas scrubbing pipe assembly. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-4 The utility model provides a technical solution: a multi-stage yellow phosphorus tail gas washing pipeline assembly, comprising a tail gas delivery pipeline 1, with electric butterfly valves 10 fixedly installed at both ends of the tail gas delivery pipeline 1. When the electric butterfly valves 10 are closed, a closed space can be formed between the two electric butterfly valves 10, which is conducive to the entry of liquid medicine for treatment operations;

[0026] Specifically, a sewage pipe 11 is fixedly installed at the bottom position of the end tube body of the exhaust gas conveying pipeline 1, and a first valve 111 is fixedly installed on the sewage pipe 11 to facilitate the subsequent discharge of waste water; a multi-stage washing component 2 is provided on the exhaust gas conveying pipeline 1, and the multi-stage washing component 2 includes a plurality of liquid storage cylinders 20 for storing corresponding liquid medicines. A solenoid valve 24 is provided on one side of the liquid medicine storage cylinder 20, and the liquid medicine storage cylinder 20 and the corresponding liquid inlet pipe on the solenoid valve 24 are connected through a liquid medicine pipe 25. A delivery pump 26 is provided on one side of the solenoid valve 24, and the delivery pump 26 and the solenoid valve 24 are connected through a delivery pipe 27. The liquid outlet end of the delivery pump 26 is connected to the exhaust gas conveying pipeline 1 through an outflow pipe 28, so that the delivery pump 26 is used to deliver the liquid medicine in the corresponding liquid medicine storage cylinder 20 to the exhaust gas conveying pipeline 1 for processing.

[0027] In this embodiment, the liquid medicine storage cylinder 20 is provided with a transparent plate 201 arranged along the height direction of the liquid medicine storage cylinder 20 . The transparent plate 201 is a transparent plate structure, which facilitates observation of the liquid medicine amount in the liquid medicine storage cylinder 20 through the transparent plate 201 .

[0028] Specifically, a top cover 21 is fixedly installed on the top of the medicine storage cylinder 20, and an adding tube 22 is fixedly installed at the center position of the top cover 21 to facilitate the addition of medicine into the medicine storage cylinder 20; a dust cover 23 is hinged on the top surface of the adding tube 22 through a hinge, and when the dust cover 23 is closed, it covers the upper surface of the adding tube 22 to provide dust-proof protection.

[0029] Furthermore, an exhaust pipe 12 is fixedly mounted on the top pipe body of the exhaust gas delivery pipe 1 , and a second valve 121 is fixedly mounted on the exhaust pipe 12 , so that when adding liquid medicine into the exhaust gas delivery pipe 1 , the second valve 121 can be opened to perform exhaust operation.

[0030] In addition, a bent pipe 13 is fixedly installed at the end of the exhaust pipe 12, and the end pipe opening of the bent pipe 13 is set to face downward, which has the effect of blocking the entry of dust; the bent pipe 13 is a transparent tube body, which is convenient for observing whether the amount of liquid medicine in the exhaust gas delivery pipeline 1 flows out from the bent pipe 13.

[0031] It is worth noting that a pad 14 is fixedly installed on the top pipe body of the exhaust gas conveying pipe 1, and an ultrasonic oscillator 141 is fixedly installed on the pad 14. The transmitting end of the ultrasonic oscillator 141 is inserted into the exhaust gas conveying pipe 1, so that the ultrasonic oscillator 141 is used to promote water vibration and improve the cleaning effect on the inner wall of the exhaust gas conveying pipe 1.

[0032] It is worth noting that the outer diameter of the sewage pipe 11 is 5 cm to 10 cm, which is conducive to discharging sewage more quickly.

[0033] When the yellow phosphorus tail gas multi-stage washing pipeline assembly of the present invention is in use, the electric butterfly valve 10 is closed. At this time, the space between the two electric butterfly valves 10 is a closed structure. Then the solenoid valve 24 is opened until the corresponding liquid medicine pipe 25 is connected to the delivery pipe 27. At the same time, the second valve 121 is opened, and the delivery pump 26 is connected to the external power supply and made to work. When the delivery pump 26 works, the liquid medicine in the liquid medicine storage cylinder 20 is delivered to the tail gas delivery pipeline 1, and the impurities on the inner wall of the tail gas delivery pipeline 1 are cleaned. After a period of reaction, the first valve 111 is opened to discharge the sewage from the sewage pipe 11, which is convenient to use.
