Abstract

The utility model relates to a device for improving the yield of terephthalic acid. The device comprises a metal sintering filter element (1) and a tank body (2), wherein the metal sintering filter element (1) is fixedly positioned in the middle position of the inner chamber of the tank body (2); a drain outlet (4) is positioned on the lower end of the tank body (2); a condensation opening (6) is fixed at the right side of the drain outlet (4); and a feeding hole (3) is arranged on the tank body (2) at the left side above the discharging hole (4). The device has good filtering effect and high solid recovery rate, can effectively reduce the unit consumption of PX, and simultaneously reduce the COD of wastewater effectively. Simultaneously, the metal sintering filter element has high strength, long service life and low maintenance cost.

Description

Improve the device of terephthalic acid (TPA) yield
Technical field
The utility model belongs to the petrochemical equipment field, particularly relates to a kind of device that improves the terephthalic acid (TPA) yield.
Background technology
Existing filter filter effect is not high, needs to filter repeatedly, thereby has increased production cost.
F-177 is the filter of metal sintering filter core, material is 2205DSS, by P-302 the CTA mother liquor is delivered among the F-177, under the effect of pressure, filtrate is passed the metal sintering filter core, and filter cake forms at the filter element inner surface, waits filter element pressure reduction to reach 3Barg, program skips to blanking, and blanking finishes the back circulation and refilters.99% the solid particle greater than 0.5um can be reclaimed by this device, filtrate after filtering is transported to reclaim in the acetic acid evaporimeter and handles.
Technological principle:
Program step was divided into for 9 steps: the first step: filter.Second step: isolate.The 3rd step: discharging.The 4th step: acid bubble 1.The 5th step: pressurization 1.The 6th step: discharging 1.The 7th step: acid bubble 2.The 8th step: pressurization 2.The 9th step: discharging 2.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of device that improves the terephthalic acid (TPA) yield, is used for improving the terephthalic acid (TPA) yield.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of device that improves the terephthalic acid (TPA) yield is provided, comprise metal sintering filter core and tank body, described metal sintering filter core is fixed in the tank inner chamber middle position, floss hole is positioned at the tank body lower end, the condensation mouth is fixed in the floss hole right side, and charging aperture is positioned on the tank body in left side, floss hole top.
Described tank body upper left-hand has the purgative gas inlet.
Beneficial effect
The utility model good filtration effect, the solid recovery rate height can effectively reduce the unit consumption of PX, can effectively reduce the COD of waste water simultaneously; The metal sintering filer element strength is big simultaneously, and the life-span is long, and maintenance cost is low.
Description of drawings
Fig. 1 is the utility model cutaway view,
Among the figure: 1-metal sintering filter core, 2-tank body, 3-charging aperture, 4-floss hole, 5-purgative gas inlet, 6-condensation mouth.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
