Abstract
The utility model relates to a new device for recovering PTA (Purified Terephthalic Acid) energy, which comprises an emptying port (7), a boiler water heater (9) and a desalted water heater (10), wherein the emptying port (7) is positioned on the top of a boiler main body (8), and a spray washer (1) is positioned below the emptying port (7); the boiler water heater (9) is positioned in the inner chamber of the boiler main body (8) below the spray washer (1), and the upper part and the lower part of the boiler water heater (9) are respectively communicated with a boiler water inlet pipe (2) and a boiler water return pipe (3); the desalted water heater (10) is positioned in the inner chamber of the boiler main body (8) at the lower part of the boiler water heater (9); and a steam inlet (6) is positioned in the middle of the inner chamber of the boiler main body (8) below the boiler water heater (9). While meeting the technical and environmental-protection requirements, the new device also avoids secondary waste of energy.
Description
Technical field
The utility model belongs to the petrochemical equipment field, particularly relates to a kind of p-phthalic acid's energy and reclaims new equipment.
Background technology
In traditional PTA technology, the energy major part that refining workshop section produces forms by the crystallizer flash distillation, and most energy recycles at warm-up phase, and the atmospheric flashing steam that more remaining energy and recovery difficult are bigger all can carry out collection and treatment at last in refining washing tail gas jar.In the present PTA device, it generally is the desalted water that adopts the refining workshop section of heating earlier making beating usefulness, reclaim portion of energy wherein, for environmental protection requirement, the direct emptying of PTA dust of avoiding steam and carrying secretly is with the directly emptying of cooler cooling back then, so not only do not make full use of the waste heat of device itself, cause the loss of big energy on the contrary, also will provide a large amount of recirculated cooling waters to come cooling medium simultaneously, additionally increased energy consumption.Take all factors into consideration according to the actual energy demand of full factory now, refining tail gas washing tower energy remaining is recycled, existing heat exchanger is transformed, at first increase the heat exchange area of the desalted water heater of the refining making beating of heating usefulness, the waste heat that utilizes as much as possible, energy remaining is no longer used water quench then, but is used for the heating boiler moisturizing, thereby reduces the steam consumption of the deoxygenation of boiler.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of p-phthalic acid's energy and reclaims new equipment, comprise drain, boiler water heater and desalted water heater is characterized in that: described drain is positioned at the boiler body top, and sprayer-washer is positioned at the drain below; The boiler water heater is positioned at the boiler body inner chamber of sprayer-washer below, and boiler water heater upper and lower is communicated with boiler water inlet pipe and boiler blow-down water pipe respectively; The desalted water heater be positioned at boiler water heater bottom the boiler body inner chamber; Steam-gas inlet is positioned at the boiler body inner chamber middle part of boiler water heater below.
Described desalted water heater upper and lower is communicated with desalination outlet pipe and desalination water inlet pipe respectively.
Beneficial effect
The utility model when satisfying technology and environmental protection requirement, has also been avoided the secondary waste of energy like this.
Description of drawings
Fig. 1 is the utility model structure chart.
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.
As shown in Figure 1, a kind of p-phthalic acid's energy reclaims new equipment, comprises drain 7, boiler water heater 9 and desalted water heater 10, and described drain 7 is positioned at boiler body 8 tops, and sprayer-washer 1 is positioned at drain 7 belows; Boiler water heater 9 is positioned at boiler body 8 inner chambers of sprayer-washer 1 below, and boiler water heater 9 upper and lowers are communicated with boiler water inlet pipe 2 and boiler blow-down water pipe 3 respectively; Desalted water heater 10 be positioned at boiler water heater 9 bottoms boiler body 8 inner chambers; Steam-gas inlet 6 is positioned at the boiler body 8 inner chambers middle part of boiler water heater 9 belows.Desalted water heater 10 upper and lowers are communicated with desalination outlet pipe 4 and desalination water inlet pipe 5 respectively.
Claims (2)
1. p-phthalic acid's energy reclaims new equipment, comprise drain (7), boiler water heater (9) and desalted water heater (10) is characterized in that: described drain (7) is positioned at boiler body (8) top, and sprayer-washer (1) is positioned at drain (7) below; Boiler water heater (9) is positioned at boiler body (8) inner chamber of sprayer-washer (1) below, and boiler water heater (9) upper and lower is communicated with boiler water inlet pipe (2) and boiler blow-down water pipe (3) respectively; Desalted water heater (10) be positioned at boiler water heater (9) bottom boiler body (8) inner chamber; Steam-gas inlet (6) is positioned at boiler body (8) the inner chamber middle part of boiler water heater (9) below.
