The invention discloses an automatic decontamination device and a decontamination method for a regeneration module of a vacuum hydrocarbon solvent cleaning machine. The invention automatically and timely cleans dirt, improves the working efficiency of oil stain treatment of the regeneration module, has good sealing performance and improves the regeneration performance.
Description
Technical Field
The invention belongs to the field of vacuum hydrocarbon cleaning devices, and particularly relates to an automatic waste oil cleaning device and a dirt cleaning method for a hydrocarbon regeneration module of vacuum hydrocarbon cleaning equipment.
Background
With the development and upgrade of industrial technologies, the environmental protection requirements in China and even around the world are becoming more and more severe. The traditional industrial cleaning equipment (water-based cleaning equipment) cannot meet the requirements of precise cleaning and high-end cleaning. Meanwhile, the problem of subsequent water treatment brought by the traditional industrial cleaning equipment (water-based cleaning equipment) is increasingly urgent. Based on the above factors, in the eight and ninety years of the last century, high-tech enterprises represented by dull, NACHI, and IHI of japan, germany, have introduced a new high-end industrial cleaning apparatus using a hydrocarbon solvent as a cleaning medium and assisting a vacuum technique. Vacuum hydrocarbon solvent cleaners also face troublesome problems during use, such as "waste oil disposal of solvent regeneration modules".
As the name implies, "solvent regeneration" refers to the conversion of a relatively clean hydrocarbon solvent into a relatively unclean hydrocarbon solvent after the clean hydrocarbon solvent comes into contact with a workpiece to be cleaned, and the unclean hydrocarbon solvent needs to be sent to a solvent regeneration module to be treated. The relatively unclean solvent is separated into clean solvent and waste oil (oil stain) that needs to be discharged.
Aiming at the mainstream vacuum hydrocarbon solvent cleaning machine in the current market, the waste oil treatment of the solvent regeneration module mainly adopts the mode of 'overhaul' or opening a 'maintenance hole', and the high-pressure gun is utilized to perform high-pressure washing on the waste oil inside. Above-mentioned processing form has reduced the work efficiency of equipment on the one hand, has increaseed the working strength that the equipment overhauld simultaneously.
As shown in the attached fig. 1, the solvent regeneration module of a typical vacuum hydrocarbon solvent cleaning machine is provided. The regeneration of the solvent and the separation of the used oil (greasy dirt) are integrated in one module. In this type of solvent regeneration module, a solvent regeneration tank 1 is connected to a waste oil heating tank 3 at the bottom by a flange. The waste oil is heated on the surface of the heating plate 2, the waste oil (greasy dirt) can be solidified on the surface of the heating plate 2 after a period of time, and if the waste oil is not treated, the regeneration capability of a solvent and the discharge capability of the waste oil can be seriously influenced. In general, the time for overhaul is set, and the solvent regeneration tank 1 and the waste oil heating tank 3 at the bottom are released from the fastening relationship in the stage of overhaul, and the whole is lifted off. Thereby cleaning the heating plate 2. And the waste oil (greasy dirt) is discharged to a waste oil groove 5 through a waste oil discharge electromagnetic valve 4 at the bottom.
The solvent regeneration module of the vacuum hydrocarbon solvent cleaning machine with the structure is similar to the solvent regeneration module of the vacuum hydrocarbon solvent cleaning machine with the structure shown in the specification and the attached figure 2, and the solvent regeneration module of the vacuum hydrocarbon solvent cleaning machine with the structure is similar to the solvent regeneration module of the vacuum hydrocarbon solvent cleaning machine with the specification and the attached figure 1. The difference is that the regeneration module is provided with an access hole 11. The access opening 11 is externally sealed in the form of a flange. As described above, when the waste oil (oil stain) on the surface of the heating plate 2 is cleaned, the flange of the access opening 11 is detached, and the heating plate 2 is cleaned with the high-pressure gun.
The solvent regeneration modules of the two typical vacuum hydrocarbon solvent cleaning machines have the following disadvantages:
1. cannot be overhauled in time
When a solvent regeneration module of the vacuum hydrocarbon solvent cleaning machine is used, the cleanliness of workpieces, the oil stain type and other factors are not in a standard state, and a standard state does not exist. Therefore, the overhaul oil cleaning time of the regeneration module is different and even has larger difference. The overhaul intervals given by the equipment use guidelines are not representative. That is, the overhaul schedule of different enterprises is formulated according to the overhaul time of the instruction book, so that the overhaul is executed after the regeneration performance of the regeneration module is weakened to a serious degree possibly;
2. complicated operation
Description the cleaning of the heating plate 2 of figure 1, which is equivalent to the dismantling of the plant, involves considerable field work, which is a challenge for the maintenance sector of the enterprise. The attached figure 1 cannot avoid the disassembly work of the equipment, and the workload is a little bit smaller than that of the first structure.
3. Reduce the working efficiency
Because the solvent regeneration modules of the two conventional vacuum hydrocarbon solvent cleaning machines need to be shut down for overhaul, the working efficiency is seriously reduced;
4. affecting the sealing performance of the solvent regeneration tank
Both modes bring an uncontrolled risk to the sealing performance of the device. After the overhaul of the specification and the attached drawing 1 is finished, the sealing performance of the regeneration module needs to be checked again, and the opening and closing processes of the maintenance port 11 of the specification and the attached drawing 2 are easy to leak.
