Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vinylidene fluoride synthesis technology and relates to an alkaline washing tower cleaning device. Background Technology
[0002] Vinylidene fluoride (VDF) production uses R142b as raw material. After vaporization and preheating, it undergoes cracking to obtain high-temperature cracked gas. This gas is then cooled, dust-removed, and passed through a water washing tower and an alkali washing tower to remove acidic gases such as hydrogen chloride and hydrogen fluoride. The alkali washing tower uses acid-base neutralization to remove hydrogen chloride and hydrogen fluoride. The alkali solution reacts with hydrogen chloride and hydrogen fluoride to produce sodium chloride and sodium fluoride, respectively. After the alkali washing tower has been running for a period of time, sodium chloride and sodium fluoride will scale on the packing inside the tower, clogging it and affecting its operation. At this point, the alkali washing tower needs to be flushed. However, the conventional method of flushing with tap water is not only slow but also insufficiently clean. Utility Model Content
[0003] The purpose of this invention is to address the problems existing in the prior art by providing an alkaline washing tower cleaning device, which solves the problems of slow washing efficiency and incomplete cleaning that often occur when using tap water to wash alkaline washing towers in vinylidene fluoride production.
[0004] Therefore, the present invention adopts the following technical solution: An alkaline scrubbing tower cleaning device includes an alkaline scrubbing tower, a heater, a water tank, and a transfer pump; The alkaline washing tower is connected to the heater through the alkaline washing tower inlet pipe and to the water tank through the water tank inlet pipe; The heater is equipped with a hot water supply pipe and a hot water return pipe. The heater is connected to the delivery pump through the heater inlet pipe, and the delivery pump is connected to the water tank through the delivery pump inlet pipe. The water tank is equipped with a production water pipe and a level gauge. The production water pipe is equipped with a third regulating valve, and the level gauge and the third regulating valve are interlocked.
[0005] The inlet pipe of the alkaline washing tower is equipped with a thermometer.
[0006] The hot water supply pipe is equipped with a first regulating valve, which is interlocked with the thermometer.
[0007] The heater inlet pipe is equipped with a flow meter and a second regulating valve, and the two are interlocked.
[0008] The beneficial effects of this utility model are as follows: In use, this invention utilizes a delivery pump to pump the production water heated by the heater into the alkaline washing tower, which then flows by gravity into the water tank for circulating cleaning of the alkaline washing tower, thereby improving the cleaning efficiency and effectiveness of the alkaline washing tower. This invention is also characterized by easy maintenance and long service life. Attached Figure Description

Detailed Implementation
[0011] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.
[0012] like Figure 1 As shown, an alkaline washing tower cleaning device includes an alkaline washing tower 1, a heater 6, a water tank 14, and a transfer pump 16. The alkaline washing tower 1 is connected to the heater 6 through an alkaline washing tower inlet pipe 2 and to the water tank 14 through a water tank inlet pipe 13. The heater 6 is provided with a hot water supply pipe 5 and a hot water return pipe 7. The heater 6 is connected to the transfer pump 16 through a heater inlet pipe 10, and the transfer pump 16 is connected to the water tank 14 through a transfer pump inlet pipe 15.
[0013] The water tank 14 is equipped with a production water pipe 9 and a level gauge 17. The production water pipe 9 is equipped with a third regulating valve 8. The level gauge 17 and the third regulating valve 8 are interlocked. The third regulating valve 8 controls the water tank level to 50%.
[0014] The inlet pipe 2 of the alkali washing tower is equipped with a thermometer 3, and the hot water supply pipe 5 is equipped with a first regulating valve 4, which is interlocked with the thermometer 3. The first regulating valve 4 controls the inlet water temperature of the alkali washing tower 1 at 60℃.
[0015] The heater inlet pipe 10 is equipped with a flow meter 11 and a second regulating valve 12, which are interlocked. The second regulating valve 12 controls the production water circulation rate to 10 Nm³. 3 / h.
[0016] During use, the third regulating valve 8 is opened to inject production water into the water tank 14. When the liquid level in the water tank 14 reaches 70%, the transfer pump 16 is started. The production water in the water tank 14 is heated by the heater 6 and enters from the top of the alkali washing tower 1. It then flows by gravity from the bottom of the alkali washing tower 1 to the water tank 14, thereby achieving the circulation cleaning of the alkali washing tower 1 through the transfer pump 16.
