Abstract
A fixed tube-sheet heat exchanger relates to a fixed tube heat exchanger. The utility model aims to solve the problems of difficulty of mechanical cleaning of U-shaped bent parts, low heat conduction and frequent halting times caused by the medium leaking in a tube due to easy abrasion of the existing U-shaped tube heat exchanger. The fixed tube-sheet heat exchanger comprises a heat exchange shell and N heat exchange tubes which are arranged in the inner cavity of the heat exchange shell, wherein N is an integer greater than 1; the fixed tube-sheet heat exchanger also comprises a partition plate and an air cavity chamber; the partition plate is arranged in the inner cavity of the heat exchanger shell; N through holes are formed in the surface of the partition plate; the N holes are respectively correspondingly connected with the right end parts of the N heat exchange tubes; the outer edge of the side wall of the partition plate is in fixed contact connection with the inner wall of the heat exchanger shell; the partition plate and the right end of the inner cavity of the heat exchanger shell form the air cavity chamber. The fixed tube-sheet heat exchanger is suitable for the fixed tube heat exchanger.
Description
Technical field
The utility model relates to stationary pipes heat exchanger.
Background technology
At present in synthetic water cooler, adopt U-shaped pipe heat exchanger, this heat exchanger is difficult to that mechanical cleaning, heat exchanger tube inconvenience change, pipe mid portion gap is large, the heat output of unit capacity and unit mass is low; And when heat exchanger diameter is larger, U-shaped crook is supported with difficulty, in U-shaped crook easy fracture or wearing and tearing, causes managing interior medium and easily leak, restrain that resistance to shock is poor and stop frequency is frequent.
Utility model content
The purpose of this utility model is that to exist U-shaped crook to be difficult to mechanical cleaning, heat output low and easy to wearly cause managing interior medium and easily leak the stop frequency problem frequently causing in order to solve existing U-shaped pipe heat exchanger, and a kind of fixed tube-sheet exchanger is provided.
A kind of fixed tube-sheet exchanger, it comprises heat exchanger shell and N root heat exchanger tube, N root heat exchanger tube is arranged in the inner chamber of heat exchanger shell, N is greater than 1 natural number, it also comprises dividing plate and gas chamber, dividing plate is arranged in the inner chamber of heat exchanger shell, the surface of dividing plate has N penetrating hole, described N hole correspondence is fixedly connected with the right part of N root heat exchanger tube respectively, the outward flange of the sidewall of dividing plate contacts and is fixedly connected with the inwall of heat exchanger shell, and the right-hand member of dividing plate and heat exchanger shell inner chamber forms gas chamber.
The gas chamber that the utility model is separated out by dividing plate replaces the U-shaped pipe in existing heat exchanger, make the assorted dirt of tube wall and liquid because the effect of the process gas pressure in tube side is washed into gas chamber, be convenient to the mechanical cleaning of tube side, increased heat transfer area, thoroughly solved that U-shaped crook is easy to wear to cause managing interior medium and easily leak the system shutdown causing.The utlity model has simple in structure, compact, heat transfer area and increase and make cooling velocity accelerate and can bear higher pressure, the temperature of heat exchanger delivery port is reduced to 40 ℃ by before 60 ℃.Extend the production run cycle, improved the economic benefit of company.
Accompanying drawing explanation
Fig. 1 is main cutaway view of the present utility model, the structural representation that Fig. 2 is existing heat exchanger.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, a kind of fixed tube-sheet exchanger described in present embodiment, it comprises heat exchanger shell 3 and N root heat exchanger tube 2, N root heat exchanger tube 2 is arranged in the inner chamber of heat exchanger shell 3, N is greater than 1 natural number, it also comprises dividing plate 1 and gas chamber 4, dividing plate 1 is arranged in the inner chamber of heat exchanger shell 3, the surface of dividing plate 1 has N penetrating hole, described N hole correspondence is fixedly connected with the right part of N root heat exchanger tube 2 respectively, the outward flange of the sidewall of dividing plate 1 contacts and is fixedly connected with the inwall of heat exchanger shell 3, dividing plate 1 forms gas chamber 4 with the right-hand member of heat exchanger shell 3 inner chambers.
The utility model forms gas chamber 4 by dividing plate 1 and the right-hand member of heat exchanger shell 3 inner chambers, replaces the U-shaped pipe in existing heat exchanger, and tube side is the process gas from gas-gas heat exchanger, and after Heat Exchanger in Circulating Water System, process gas goes methanol separator to carry out gas-liquid separation; When the process gas in tube side enters gas chamber 4, due to the effect of pressure, the assorted dirt of tube wall and liquid can be poured to gas chamber 4, and work as process gas, from gas chamber 4, again enter tube side, because the proportion of assorted dirt and liquid is trapped in gas chamber 4 much larger than the proportion of process gas; Thereby reduced the number of times that cleans tube side.
For being trapped in the assorted dirt of gas chamber 4, be convenient to mechanical cleaning; Because the utility model no longer retains U-shaped bend pipe, thereby thoroughly solved, U-shaped crook is easy to wear to cause managing interior medium and easily leaks the system shutdown causing.
On shell side of the present utility model, water carrys out supply mains on self-circulating water, and backwater removes recirculated water return main line.
Gas chamber 4 adopts existing shell side showering guilding valve and atmospheric valve showering guilding valve and the atmospheric valve as gas chamber 4.
The specific embodiment two: in conjunction with Fig. 1, present embodiment is described, present embodiment is the further restriction to a kind of fixed tube-sheet exchanger described in the specific embodiment one, and dividing plate 1 adopts metallic plate.
The specific embodiment three: present embodiment is described in conjunction with Fig. 1, present embodiment is the further restriction to a kind of fixed tube-sheet exchanger described in the specific embodiment one, it also comprises housing atmospheric valve 3-1 and housing showering guilding valve 3-2, housing atmospheric valve 3-1 is arranged on the top of heat exchanger shell 3, and the bottom of corresponding heat exchanger shell 3 arranges housing showering guilding valve 3-2.
The utility model is showering guilding valve and the atmospheric valve as shell side by the housing showering guilding valve 3-2 that sets up and housing atmospheric valve 3-1.
The specific embodiment four: in conjunction with Fig. 1, present embodiment is described, present embodiment is the further restriction to a kind of fixed tube-sheet exchanger described in the specific embodiment one, and it also comprises access hole 3-3, and access hole 3-3 is arranged on the middle part of heat exchanger shell 3 right-hand members.
The setting of access hole 3-3, cleans tube side convenient, and damaged tubular is easier to change.
