Treatment process for recycling stainless steel intalox saddle packing

Abstract

The invention provides a treatment process for recycling stainless steel intalox saddle packing, which comprises the following steps of: putting the stainless steel intalox saddle packing into an incineration device, heating and incinerating at low temperature, adding a certain proportion of cleaning agent, heating and incinerating at medium temperature, adding a certain proportion of cleaning agent again, and heating and incinerating at medium temperature to obtain the stainless steel intalox saddle packing. Finally, high-temperature heating incineration is conducted, after heat preservation is conducted for a period of time, the stainless steel intalox saddle packing is taken out, and then a cleaning agent is sprayed; according to the method, the stainless steel intalox saddle packing is treated in a gradient incineration desorption mode in combination with a cleaning agent, so that attached carbides are incinerated and desorbed thoroughly, the original function of the stainless steel packing is guaranteed, cyclic utilization of the carbonized intalox saddle packing is achieved, and the physical property of the carbonized intalox saddle packing is not changed; efficient and clean treatment can be realized in an extremely short time, the cost is lower, and the effect is obvious; and the treated intalox saddle packing is recycled, so that great expenditure is saved for a production line, and higher economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of rectangular saddle ring packing, in particular to a treatment process for the recycling of stainless steel rectangular saddle ring packing. Background technique [0002] After the stainless steel saddle ring packing is used for a period of time in the tower for removing heavy components, a large amount of nitro substances will carbonize and coke and adhere to it, which will reduce the separation effect of the packing if it is light, and block the inner space of the tower if it is serious, causing safety hazards . After the filler is carbonized and coked at high temperature, the following methods are generally selected for cleaning: one is the mechanical removal method, which uses high-pressure water guns and manual treatment to impact the carbonized coke, but the removal rate of this method is very low; the other is to use solvents for cleaning Through a large number of experiments, it was found that the...

[0002] After the stainless steel saddle ring packing is used for a period of time in the tower for removing heavy components, a large amount of nitro substances will carbonize and coke and adhere to it, which will reduce the separation effect of the packing if it is light, and block the inner space of the tower if it is serious, causing safety hazards

After the filler is carbonized and coked at high temperature, the following methods are generally selected for cleaning: one is the mechanical removal method, which uses high-pressure water guns and manual treatment to impact the carbonized coke, but the removal rate of this method is very low; the other is to use solvents for cleaning Through a large number of experiments, it was found that the cleaning agent with the best effect can only partially dissolve the carbonized coke, it is difficult to completely remove it, and the cost is too high, exceeding the cost of new purchases; this type of carbonized material can be removed mechanically and chemically. Solvent removal is ineffective and time consuming

If the packing is directly replaced, first, it will cause waste of packing, and second, the contaminated packing will be regarded as hazardous waste if it cannot be disposed of.
