Abstract
The utility model discloses a polyester gathers EG hot well purifier of EG circulation system eventually, including the hot well jar of EG, be equipped with flat filter screen on the hot well jar of EG, the EG leads into flat filter screen one side through the liquid outlet of slagging-off machine, and the hot well jar of EG still passes through drain pipe intercommunication pump prefilter, and the slope still is equipped with the inclined baffle in the hot well jar of EG, and the inclined baffle is by the lateral wall tilt up of EG hot well tank bottoms one side towards relative opposite side. This polyester gathers EG hot well purifier of EG circulation system finally conveniently clears out jar internal floccule, avoids the residue to pile up in a large number and reduces the residue and blocks up the pre-pump filter.
Description
The technical field is as follows:
the utility model relates to a polyester production field specifically says a polyester end gathers EG hot-well purifier of EG circulation system.
Background art:
in the production process, the main source of residue in the system is that mist entrainment is generated in the process of vacuumizing a final polymerization kettle and sprayed by a final polymerization spraying condenser, then the mist entrainment returns to a final polymerization liquid sealing tank, then a slag extractor is introduced into a flat filter screen at the upper end of the final polymerization heat well tank, and part of large blocky residue is cleaned from the tail end of the filter screen.
The utility model has the following contents:
the utility model aims to solve the technical problem that a conveniently clear out jar internal floccule, avoid the residue to pile up in a large number and reduce the polyester of residue jam pre-pump filter and gather EG circulating system's EG hot-well purifier finally is provided.
The utility model provides a technical solution is that, an EG hot well purification device of a polyester final polymerization EG circulation system is provided, which comprises an EG hot well tank, a flat plate type filter screen is arranged on the EG hot well tank, EG is led into one side of the flat plate type filter screen through a liquid outlet of a slag remover, the EG hot well tank is communicated with a pre-pump filter through a liquid outlet pipe, an inclined baffle is also obliquely arranged in the EG hot well tank, the inclined baffle is upwards inclined from one side of the bottom of the EG hot well tank to the side wall of the opposite side, the upper end of the inclined baffle is supported against the inner wall of the EG hot well tank and is positioned at one side of the liquid outlet far away from the slag remover, the inclined baffle divides the EG hot well tank into a first containing cavity positioned above the baffle and a second containing cavity positioned below the baffle, a diversion through hole is arranged at the upper part of the inclined baffle, the liquid outlet pipe is communicated with the EG hot well tank and is communicated with the second containing cavity, a slag suction pipe is arranged at the bottom in the first containing cavity, a slag suction hole is arranged on the slag suction pipe, inhale sediment pipe one end and seal, inhale the sediment pipe other end and be connected with the diaphragm pump, the diaphragm pump is arranged in the EG accumulator.
Compared with the prior art after the structure more than adopting, the utility model has the advantages of it is following: EG is introduced by the mucking machine and is finally gathered flat filter screen in hot well jar upper end, the great cubic residue of part is cleared up from the filter screen tail end, EG gets into the first appearance chamber of the hot well jar of EG, residue powder and oligomer enter into hot well jar bottom and pile up, rise along with the liquid level, EG flows to the second and holds the chamber and carry out two times through the filter before the pump and filter back entering circulation system, at this moment, most such as flocculus and oligomer still remain first appearance chamber bottom, regularly open the diaphragm pump with these deposits take out from first appearance chamber can, thereby ensure that the EG that gets into the second and hold the chamber is comparatively clean.
Preferably, the cross section of the slag suction pipe is hexagonal, and each side surface is provided with a strip seam arranged along the length direction. The slag suction effect is good.
Furthermore, the periphery of the inclined baffle is welded and fixed with the inner wall of the EG hot well tank.
Description of the drawings:
fig. 1 is a schematic structural diagram of the present invention.
The specific implementation mode is as follows:
the invention will be further explained with reference to the drawings and the detailed description below:
as shown in figure 1, the EG hot well purification device of the polyester final polymerization EG circulating system comprises an EG hot well tank 1, wherein a flat filter screen 2 is embedded in an opening at the top of the EG hot well tank 1, EG is guided into one side of the flat filter screen 2 through a liquid outlet of a slag remover 3 of the polyester final polymerization EG circulating system, the EG hot well tank 1 is further communicated with a pre-pump filter 9 through a liquid outlet pipe 4, the liquid outlet pipe 4 penetrates through the EG hot well tank and is subjected to welding and sealing treatment at the penetrating position, an inclined baffle plate 5 is further obliquely arranged in the EG hot well tank 1, the periphery of the inclined baffle plate 5 is fixedly welded with the inner wall of the EG hot well tank, the inclined baffle plate 5 is upwards inclined from one side of the bottom of the EG hot well tank to the side wall opposite to the other side, the upper end of the inclined baffle plate 5 is abutted against the inner wall of the EG hot well tank and is positioned at one side far away from the liquid outlet of the slag remover, the inclined baffle plate 5 divides the EG hot well tank into a first containing cavity positioned above the baffle plate and a second containing cavity positioned below the baffle plate, like this EG gets into first appearance chamber when flat filter screen 2 is leading-in, 5 upper portions of baffle to one side have the water conservancy diversion through hole, the water conservancy diversion through hole is horizontal strip opening, drain pipe 4 link up the hot well jar of EG and hold the chamber intercommunication with the second, the bottom still is equipped with inhales slag pipe 6 in the first appearance chamber, inhale slag pipe 6 and place in the contained angle that inclined baffle 5 and the hot well jar 1 inner wall of EG formed, inhale slag pipe 6 and be the straight tube, inhale slag pipe cross-section and be the hexagon, and set up the strip seam that sets up along length direction on each side, be equipped with on inhaling slag pipe and inhale the slag hole, inhale slag pipe one end and seal, inhale slag pipe 6 other end and be connected with diaphragm pump 7 through connecting pipe 10, diaphragm pump 7 is arranged in EG accumulator recovery tank 8, when the diaphragm pump deposit is more, the accessible is opened and is taken out to the EG accumulator recovery tank, the clean EG is taken out the retrieval and utilization after the sediment of stewing.
Through the utility model discloses an implement, technology circulation system is cleaner, has effectively reduced unusual pump number of times and frequency of cutting, has reached the purpose that technology is stable and reduce the power consumption.
The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims. All the equivalent structures or equivalent flow changes made by using the contents of the specification and the attached drawings of the utility model are included in the patent protection scope of the utility model.
