Description
Technical Field
The utility model relates to a automatically cleaning solid-liquid separation system for containing sediment danger waste liquid.
Background
In the production process of chemical plants, various hazardous waste liquids are generally produced. Therefore, the hazardous waste liquid needs to be incinerated and disposed in a centralized manner. The hazardous waste liquid is usually a heterogeneous mixture, i.e. contains slag, so that the hazardous waste liquid needs to be pretreated before entering the incineration device so as to reduce line blockage. The pretreatment is to carry out solid-liquid separation on the hazardous waste liquid. Generally, there are two types of solid-liquid separation, i.e., natural settling or filtration. The natural sedimentation mode is to realize solid-liquid separation through the action of gravity; the filter screen mode is that the pressure of the pump acts on the filter device to realize solid-liquid separation. When adopting the filter screen mode, because the fluid through the filter screen is one-way, the accumulation of filter residue can make the mesh of filter screen stop up, need the manual work to clear up after stopping up, waste time and energy, because dangerous waste liquid has certain toxicity, clear up the filter screen and can cause harm to operating personnel's healthy.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's defect and provide a automatically cleaning solid-liquid separation system for containing sediment danger waste liquid, it can not only improve the separating rate of residue in containing sediment danger waste liquid, can also reduce operating personnel and danger waste liquid's contact.
The purpose of the utility model is realized like this: a self-cleaning solid-liquid separation system for slag-containing hazardous waste liquid comprises a filtering device, a waste material storage tank, a waste material conveying pump, a slag collecting tank, a liquid conveying pump and a liquid storage tank; the solid-liquid separation system also comprises a cleaning mechanism; wherein the content of the first and second substances,
the filtering device comprises a shell and a U-shaped filter element component arranged in the shell;
the outlet of the waste material storage box is connected with a feed inlet positioned at the lower part of the shell of the filtering device through a waste material conveying pipe;
the waste conveying pump is arranged on the waste conveying pipe;
the slag collecting box is connected with a slag outlet arranged at the bottom of the shell of the filtering device through a slag discharge pipe;

Drawings
FIG. 1 is a schematic structural diagram of the self-cleaning solid-liquid separation system for the slag-containing hazardous waste liquid of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the self-cleaning solid-liquid separation system for hazardous waste liquid containing slag of the present invention includes a filtering device 3, a waste storage tank 1, a waste delivery pump 2, a slag collection tank 6, a liquid delivery pump 4, a liquid storage tank 5 and a cleaning mechanism; wherein the content of the first and second substances,
the filtering device 3 comprises a shell and a U-shaped filter element component arranged in the shell;
the outlet of the waste material storage box 1 is connected with a feed inlet positioned at the lower part of the shell of the filtering device 3 through a waste material conveying pipe;
the waste conveying pump 2 is arranged on the waste conveying pipe;
the slag collection box 6 is connected with a slag outlet arranged at the bottom of the shell of the filtering device 3 through a slag discharge pipe; a slag discharging valve 9 is also arranged on the slag discharging pipe;
the inlet of the liquid storage box 5 is connected with the water outlet positioned at the upper part of the shell of the filtering device 3 through a liquid conveying pipe;
