Problems solved by technology

[0006] The purpose of the present invention is to overcome the deficiencies in the prior art that when the vacuum pump is evacuated on the bell-type furnace, the copper coil contains oil, causing frequent damage to the vacuum pump and environmental pollution caused by a large amount of oil and gas at the exhaust port, and provides a hood furnace. The method of oil and gas separation in the exhaust belt of the bell-type furnace, through the oil and gas separation in the exhaust belt system of the bell-type furnace, ensures the safe operation of the vacuum pump, makes the production smooth, reduces the production and operation costs, and at the same time prevents the oil and gas from being discharged into the air and causing environmental pollution.

Embodiment 1

[0035] to combine figure 1 , figure 2 , image 3 and Figure 4 , a method for separating oil and gas from a bell-type furnace exhaust zone of the present embodiment, the steps are as follows:

[0036] Step 1: Put the oil-containing copper coil into the bell furnace 1, and lock the inner cover of the bell furnace 1 on the furnace platform;

[0037] Step 2: manually open the first intake valve 21, the first exhaust valve 27, the second intake valve 41 and the second exhaust valve 47; The second oil discharge valve 43 and the third oil discharge valve 45 respectively arranged at the diversion oil discharge port are in an open state;

[0038] Step 3: Start the vacuum pump 3, and after 15 seconds, give the vacuum valve 5 an electric signal to open it, and the vacuum pump 3 starts to vacuum the oil and gas in the bell furnace (1). In this embodiment, start the vacuum pump 3, and then 15 seconds later Open the vacuum valve 5 so that the vacuum pump 3 starts under no-load conditio...

Embodiment 2

[0049] A method for separating oil and gas from the exhaust gas of a bell-type furnace in this embodiment is basically the same as in Embodiment 1, except that the angle between the side of the oil-gas splitter plate 23 and the vertical line in this embodiment is 60° , the angle between the deflector 44 and the horizontal line is 65°.

Embodiment 3

[0051] A method for separating oil and gas from the exhaust zone of a bell-type furnace in this embodiment is basically the same as in Embodiment 1, except that the angle between the side of the first gas guide plate 25 and the vertical line in this embodiment is 75° °, the angle between the side of the second air guiding plate 26 and the vertical line is 60 °.

Abstract

Belonging to the technical field of oil-gas separation, the invention discloses a bell-type furnace exhaust belt oil-gas separation method. The method comprises the steps of: 1. loading an oil-containing copper roll into a bell-type furnace; 2. opening a first air inlet valve, a first exhaust valve, a second air inlet valve and a second exhaust valve, at the same time letting a second oil drain valve and a third oil drain valve both in an open state; 3. starting a vacuum pump, then sending an electricity receiving signal to a vacuum valve to make the valve open; 4. after starting the vacuum pump, letting the oil gas in the bell-type furnace pass through an oil-gas separator, the vacuum valve, the vacuum pump, and an oil gas purifier to separate oil from gas; and 5. after vacuum pumping for certain period of time in step 4, sending a power-off signal to the vacuum valve to make the valve close, and then stopping the vacuum pump. The technical scheme provided by the invention can ensure safe operation of the vacuum pump, reduce the damage frequency of the vacuum pump, lower the production operation cost, and also avoid discharging oil gas into the air to cause environmental pollution.

Description

technical field [0001] The invention relates to the technical field of oil and gas separation, and more particularly, relates to a method for separating oil and gas in a bell-type furnace exhaust belt. Background technique [0002] At present, the bell furnace needs to use a vacuum pump to extract the air in the furnace during the working process, and then inject a hydrogen-nitrogen mixed gas to protect the copper strip in the furnace from oxidation at high temperature and improve the quality of the copper strip. However, in the process of vacuuming, a certain gas flow will be formed in the hood of the closed bell furnace. Since the vacuum pressure in the vacuum pump is low, the residual oil in the copper coil will follow the air flow and enter the vacuum pump through the pipeline. When the gas contains a high amount of rolling oil, the performance of the vacuum pump will decrease after the rolling oil enters the vacuum pump, the vacuuming will slow down and the oil injectio...
