Abstract
The utility model discloses a heat exchanging device of a washing tower, which comprises a ring-shaped oblique plate and a plurality of heat exchange tubes mounted on the inner side of the wall of the urea washing tower, wherein the heat exchange tubes are mounted along the vertical direction of the urea washing tower, the ring-shaped oblique plate is arranged above the heat exchange tubes, a liquid feeding pipe casing and a liquid discharging pipe casing are mounted on the outer side of the wall of the urea washing tower, one ends of the heat exchange tubes are communicated with the liquid feeding pipe casing by penetrating through the urea washing tower wall, the other end of the heat exchange tubes are communicated with the liquid discharging pipe casing by penetrating through the urea washing tower wall, a liquid feeding pipe is mounted on the liquid feeding pipe casing, and a liquid discharging pipe is mounted on the liquid discharging pipe casing. The utility model has the advantages that as the heat exchange tubes are mounted vertically in the washing tower, and the ring-shaped oblique plate is arranged above the heat exchange tubes, both process gas and melt urea pass through the tubes, which prevents the melt urea from hanging on the wall; as a liquid preventing conical cap is arranged in the center of the urea washing tower, the process gas and the melt urea can be guided into the heat exchange tubes to exchange heat, thereby improving the heat exchanging efficiency; the utility model requires no tube plate, therefore the structure thereof is simple and reasonable, and the service life thereof is long.
Description
Technical field
The utility model relates to scrubbing tower heat-exchanger rig field, specifically is a kind of scrubbing tower heat-exchanger rig.
Background technology
In Melamine Production, the process gas that produces need wash heat exchange through scrubbing tower, because used fusing urea self has easy crystallization, the easy characteristics that produce wall built-up and obstruction on barrel during washing process gas, as adopt traditional tube sheet to add the heat exchanger tube form, the characteristics of fusing urea own can make fusing urea produce at the tube sheet place and stop up, and then may stop up the heat exchange mouth of pipe, have a strong impact on the operate as normal of equipment.
Summary of the invention
The utility model provides heat-exchanger rig in a kind of scrubbing tower, it can solve the deficiency that exists in the known technology, by in tower that heat exchanger tube is arranged in a straight line along tower body, and annular swash plate is set above heat exchanger tube, can allow process gas and fusing urea all pass through between pipe, enlarged the free air space of fusing urea, made the fusing urea can be in crystallization of heat exchanger tube place and obstruction
The utility model for achieving the above object, be achieved through the following technical solutions: a kind of scrubbing tower heat-exchanger rig, be included in urea washing Tata wall installed inside annular swash plate and some heat exchanger tubes, heat exchanger tube is installed along urea scrubbing tower vertical direction, the annular swash plate is positioned at heat exchanger tube top, feed liquor pipe box and fluid pipe box are installed in the urea washing Tata wall outside, heat exchanger tube one end passes urea washing Tata wall and is communicated with the feed tube cover, the heat exchanger tube other end passes urea washing Tata wall and is communicated with the drain pipe cover, feed tube puts the installation feed tube, and drain pipe puts the installation drain pipe.
Retaining liquid awl cap is installed on the described heat exchanger tube, and retaining liquid awl cap is positioned at urea scrubbing tower centre.
Between described heat exchanger tube joint pin is installed.
Described feed liquor pipe box is positioned at the bottom of fluid pipe box.
Advantage of the present utility model is: the perpendicular row of heat exchanger tube are installed in the scrubbing tower, and on heat exchanger tube top annular swash plate are set, process gas and fusing urea are all passed through between pipe, can not produce the fusing urea wall cling phenomenon; There is retaining liquid awl cap at urea scrubbing tower center, but water conservancy diversion process gas and fusing urea enter and carry out heat exchange between heat exchanger tube, improved heat exchange efficiency; Need not tube sheet, simple for structure reasonable; Wait so long service life.
Description of drawings
Accompanying drawing 1 is a main TV structure schematic diagram of the present utility model; Accompanying drawing 2 is A-A cross-sectional view of accompanying drawing 1.
The specific embodiment
The utility model is described in further detail for the contrast accompanying drawing:
Agent structure of the present utility model is: be included in urea scrubbing tower 4 tower wall installed inside annular swash plate 7 and some heat exchanger tubes 2, heat exchanger tube 2 is installed along urea scrubbing tower 4 vertical direction, annular swash plate 7 is positioned at heat exchanger tube 2 tops, annular swash plate 7 can make process gas and fusing urea all pass through from 2 of heat exchanger tubes, can not produce the fusing urea wall cling phenomenon.Feed liquor pipe box 1 and fluid pipe box 3 are installed in the described urea scrubbing tower 4 tower walls outside, heat exchanger tube 2 one ends pass urea scrubbing tower 4 tower walls and are communicated with feed liquor pipe box 1, heat exchanger tube 2 one ends pass urea scrubbing tower 4 tower walls and are communicated with fluid pipe box 3, feed tube 6 is installed on the feed liquor pipe box 1, drain pipe 5 is installed on the fluid pipe box 3.
Carry out heat exchange in order to guide process gas and fusing urea into heat exchanger tube 2, improve heat exchange efficiency, retaining liquid awl cap is installed on heat exchanger tube 2
, retaining liquid awl cap
Be positioned at urea scrubbing tower 4 centres.
2 of described heat exchanger tubes are installed joint pin 9, and heat exchanger tube 2 produces vibration in the time of can preventing work, improves the service life of product.
In order to improve heat exchange efficiency, preferably feed liquor pipe box 1 is arranged on the bottom of fluid pipe box 3.
