Abstract
The utility model discloses the mud interchanger in a kind of anaerobic sludge digestion, for heating the mud of different solid content.This interchanger mainly comprises outer tube and core pipe, and core pipe is movably placed in outer tube.Core pipe with upper hose and taper connection plate composition, strengthens heat transfer area primarily of seven.Outer tube two ends are Flange joint, inwall be provided with more than one group be uniformly distributed formed annular fin, formed rectification, mud is heated evenly.The advantage of this interchanger is: the mud heating being applicable to different solid content in anaerobic sludge digestion, and device structure is simple, and heat exchange efficiency is high, and foldable connecting fills, and not easily blocking is easy to maintenance cleaning.
Description
Technical field
The utility model relates to a kind of interchanger, and specifically, the utility model relates to a kind of mud interchanger for anaerobic sludge digestion.
Background technology
Along with the develop rapidly of wastewater treatment in China cause, to the requirement also increasingly stringent of the sludge treatment produced after sewage disposal, increasing New technical use is in field of sludge treatment.In numerous sludge disposal technologies, anaerobic sludge digestion has a lot of advantages, and the application in recent years in sludge treatment is more and more extensive.
Anaerobic sludge digestion is temperature required general higher than external temperature, and therefore mud is before entering anaerobic digestion facility, needs to be warmed to certain temperature.Conventional heating device is double-pipe exchanger, to be formed by connecting concentric(al) circles sleeve pipe with the standard pipe that two kinds of sizes are different, outside be shell side, inner is tube side, and two kinds of different media flowings in shell side and tube side respectively (reverse or in the same way) are to reach the effect of heat exchange.But mud has certain viscosity, after entering sleeve pipe, very easily result in blockage, and drag losses is large, heat transfer effect can reduce greatly, even occurs the situation of frequent servicing installation.
Summary of the invention
For above-mentioned existing problems, the utility model provides a kind of mud interchanger for anaerobic sludge digestion.To achieve these goals, the utility model adopts following technical scheme:
For a mud interchanger for anaerobic sludge digestion, described mud interchanger is connect by plural heat exchange unit group and forms, and the heat exchange unit at mud interchanger two ends is respectively arranged with water inlet pipe, sludge out pipe and rising pipe, enters mud pipe.
Described heat exchange unit is made up of outer tube, core pipe, flange, the inwall of outer tube is provided with more than the one group equally distributed fin forming annular, flange is fixedly installed on outer tube two ends, core pipe is made up of with upper hose a pair taper connection plate and seven, face has equally distributed through hole to taper connection wooden partition, a pair taper connection plate is positioned opposite, and water pipe two ends are connected on the through hole on taper connection plate, being placed in outer tube of core pipe activity.
Flange joint between the outer tube that described group connects heat exchange unit, between adjacent conical web plate, groove connects.
Owing to have employed above technical scheme, the utility model taper connection plate groove is connected to form heat exchanging chamber, and the fin in outer tube plays rectifying action when mud flows, and increases heat interchanging area, improves heat utilization efficiency, has saved mud heating cost.The outer tube of the mud interchanger of the utility model anaerobic sludge digestion, core pipe are easy to dismounting, install simple and convenient, are conducive to maintenance and cleaning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See accompanying drawing, a kind of mud interchanger for anaerobic sludge digestion, described mud interchanger is connect by plural heat exchange unit group and forms, described heat exchange unit is made up of outer tube 1, core pipe, flange 2, the inwall of outer tube 1 is provided with more than the one group equally distributed fin 3 forming annular, and the group of fin 3 is several to be needed to adjust according to heat exchange, and when mud flows in outer tube 1, fin 3 plays rectifying action, be conducive to heat exchange, fin 3 can also play the effect supporting water pipe 5 simultaneously.Flange 2 is fixedly installed on outer tube 1 two ends, is connected between outer tube 1 by flange 2, can assembledly dismantle, and is conducive to outer tube 1 and cleans and keep in repair.Core pipe is made up of with upper hose 5 a pair taper connection plate 6 and seven, and the quantity of water pipe 5 adjusts according to concrete sludge quality, and equally distributed water pipe 5 improves heat interchanging area, adds heat utilization efficiency.Taper connection plate 6 wall has equally distributed through hole, a pair taper connection plate 6 is positioned opposite, water pipe 5 two ends are connected on the through hole on taper connection plate 6, the activity of core pipe be placed in outer tube 1, between core pipe, groove 7 connects, taper connection plate 6 between adjacent can form heat exchanging chamber, is easy to mud heat exchange, the assembled and dismounting easy to connect of the groove 7 simultaneously between core pipe.Between the outer tube 1 that described group connects heat exchange unit, flange 2 connects, and between adjacent conical web plate 6, groove 7 connects.The heat exchange unit at mud interchanger two ends is respectively arranged with water inlet pipe 4, sludge out pipe 10 and rising pipe 8, enters mud pipe 9.Water and sludge stream reverse to adopting, mud heat exchange from water low temperature, progressively arrives high temperature, is conducive to the heat making full use of water.
