Description

A kind of imitative labyrinth shape baffle shell-and-tube heat exchanger
Technical field
The utility model relates to a kind of imitative labyrinth shape baffle shell-and-tube heat exchanger.
Background technology
Traditional shell-and-tube heat exchanger, due to long-pending more much larger than inlet/outlet pipe open area times of housing section, makes the flow velocity entering fluid container greatly reduce, and distribution space is comparatively large, and inner current difference is apart from also larger; The various forms of deflection plates of current use also some flow process dead angles of existence in various degree, make heat exchange medium flow distribution uneven, actual heat exchange effect is affected; Some impurity in fluid and suspension are also located deposition more slowly at flow velocity and are got off; Make depositional phenomenon more serious because temperature raises increasing of rear precipitation impurity, actual flow spaces is reduced further, and heat exchange effect worsens further.
Utility model content
The purpose of this utility model is to provide a kind of imitative labyrinth shape baffle shell-and-tube heat exchanger, reduces dielectric deposition, improves heat exchange efficiency.
The purpose of this utility model is achieved through the following technical solutions:
A kind of imitative labyrinth shape baffle shell-and-tube heat exchanger, comprises heat exchanger cylindrical shell, and the upper and lower two ends of heat exchanger cylindrical shell are respectively equipped with heated medium outlet and heated medium entrance; Be provided with head type bobbin carriage on the left of heat exchanger cylindrical shell, the upper and lower two ends of head type bobbin carriage are respectively equipped with heating medium inlet and Crude product input, and in head type bobbin carriage, middle part is provided with pass partition; Tube sheet is provided with between described head type bobbin carriage and heat exchanger cylindrical shell, heat-exchanging tube bundle is provided with in heat exchanger cylindrical shell, this heat-exchanging tube bundle end connects tube sheet, described heat exchanger cylindrical shell inner top is provided with some deflection plates with bottom is all parallel, the deflection plate of described heat exchanger cylindrical shell inner top and the deflection plate of heat exchanger cylindrical shell inner bottom part are distinguished arranged in a crossed manner between two, the cross section of this deflection plate is T-shaped, wherein the flange plate of deflection plate and horizontal plane, the web of deflection plate and the axes normal of heat exchanger; Horizontal baffle is provided with in the middle part of described heat-exchanging tube bundle, one end of this horizontal baffle and Tube-sheet Welding, the horizontal baffle other end is connected at the deflection plate of the rightmost side in heat exchanger cylindrical shell, and heat exchanger cylindrical shell forms a labyrinth passage by described deflection plate, horizontal baffle and tube sheet.
The beneficial effects of the utility model are: change the shape of traditional heat exchangers deflection plate, arrangement position and direction, by minimum range between labyrinth effect principle determination baffle, substantially increase heat exchanger ground heat exchange efficiency, decrease dirt deposition.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structure chart of a kind of imitative labyrinth shape baffle shell-and-tube heat exchanger described in the utility model embodiment;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
As shown in Figure 1-2, the one described in the utility model embodiment imitates labyrinth shape baffle shell-and-tube heat exchanger, comprises heat exchanger cylindrical shell 6, and the upper and lower two ends of heat exchanger cylindrical shell are respectively equipped with heated medium outlet 4 and heated medium entrance 9; Be provided with head type bobbin carriage 1 on the left of heat exchanger cylindrical shell, the upper and lower two ends of head type bobbin carriage are respectively equipped with heating medium inlet 2 and Crude product input 11, and in head type bobbin carriage, middle part is provided with pass partition 3; Tube sheet 10 is provided with between described head type bobbin carriage and heat exchanger cylindrical shell, heat-exchanging tube bundle 7 is provided with in heat exchanger cylindrical shell, this heat-exchanging tube bundle end connects tube sheet, described heat exchanger cylindrical shell inner top is provided with some deflection plates 8 with bottom is all parallel, the deflection plate of described heat exchanger cylindrical shell inner top and the deflection plate of heat exchanger cylindrical shell inner bottom part are distinguished arranged in a crossed manner between two, the opening direction of levels deflection plate is contrary, the cross section of this deflection plate is T-shaped, the wherein flange plate of deflection plate and horizontal plane, the web of deflection plate and the axes normal of heat exchanger; Horizontal baffle 5 is provided with in the middle part of described heat-exchanging tube bundle, one end of this horizontal baffle and Tube-sheet Welding, the horizontal baffle other end is connected at the deflection plate of the rightmost side in heat exchanger cylindrical shell, and heat exchanger cylindrical shell forms a labyrinth passage by described deflection plate, horizontal baffle and tube sheet.
During concrete use, head type bobbin carriage is divided into upper and lower two rooms by pass partition, heat medium enters into the top of head type bobbin carriage by top heating medium inlet, enter into afterwards in heat-exchanging tube bundle, namely tube side is walked, start quantity of heat given up, the medium after cooling is discharged from head type bobbin carriage bottom Crude product input.Heated medium enters into the bottom of heat exchanger cylindrical shell by heated medium entrance, enter heat transfer zone, heat transfer zone is divided into two-layer up and down by horizontal baffle, every layer forms passage jointly by the simplified inwall of heat exchanger, labyrinth shape deflection plate, horizontal baffle and tube sheet, this passage and shell side.Interior several heating tube composition that interts is restrained, and heated medium flows through in shell side process and continues to carry out heat exchange.Flow on the right side of heat exchanger cylindrical shell through labyrinth shape deflection plate again, close to entering into container upper strata during end socket, flowing to heat exchange again on the left of heat exchanger cylindrical shell through labyrinth shape deflection plate, finally being discharged by top Crude product input.
The utility model is selected, from its ventilative effect of increase, to reduce its a fluid stream blockage effect, overcome several aspect such as its friction effect and thermomechanical effect etc., oppositely make use of labyrinth effect principle.Namely adopt rational uiform section passage, keep the constant of flow velocity, frequently change the flow direction, reduce passage dead angle, make heat exchanger channels uniform, heat transfer evenly; Make to be heated flow medium and heat medium is countercurrent movement, form the constant temperature difference, utilize waste heat fully, improve heat exchange efficiency; Constant flow velocity and unique passage also can make impurity sedimentation significantly reduce.In use, rationally arrange the position that heated medium is imported and exported, make medium flow through distance on the heat exchanger shell length direction of about 2 times, the baffling effect of deflection plate, extends heat-transfer path effectively in addition; Baffle spacing and openings of sizes can be considered to determine according to combined factors such as inlet/outlet pipe sectional area, medium character, flow velocity, impurity contents.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
