Example (b):

referring to fig. 1-4, a garbage slurry heat exchange device comprises a housing 3, and further comprises: the heat exchanger comprises a shell body 3, a tube plate 4 symmetrically and fixedly connected in the shell body 3, twenty heat exchange tubes 14 fixedly connected on the tube plate 4, the twenty heat exchange tubes 14 are sequentially connected in series through an elbow tube 9, the elbow tube 9 is communicated with an overhaul tube 10, and a first medium inlet tube 15 and a first medium outlet tube 17 are respectively communicated on a head heat exchange tube 14 and a tail heat exchange tube 14; and the four baffle plates 6 are fixedly connected in the shell 3, the upper part of the shell 3 is communicated with a second medium outlet pipe 5, and the lower part of the shell 3 is communicated with a second medium inlet pipe 11.

The uppermost heat exchange tube 14 is communicated with a first exhaust tube 2, one end, far away from the heat exchange tube 14, of the first exhaust tube 2 extends out of the shell 3, and two ends of the heat exchange tube 14 are communicated with the elbow tube 9 through the flange 8.

The upper part of the shell 3 is communicated with an observation pipe opening 7 and a second exhaust pipe 16, the two end openings of the shell 3 are fixedly connected with annular fixing plates 18, the annular fixing plates 18 are connected with a cover plate 1 through fixing bolts 19, and the lower part of the shell 3 is communicated with a sewage discharge pipe 13.

Six support legs 12 are fixedly connected to the lower part of the shell 3.

In the using process of the device, a first medium can enter the first heat exchange tube 14 from the first medium inlet tube 15 and sequentially flows through the rest heat exchange tubes 14, the first medium flows out of the device from the first medium outlet tube 17 communicated with the last heat exchange tube 14 after heat conduction through the heat exchange tubes 14 and heat exchange with a second medium in the flowing process, the second medium enters a cavity formed by the tube plate 4 and the shell 3 through the second medium inlet tube 11 communicated with the lower part of the shell 3, and the second medium flows out of the device from the second medium outlet tube 5 communicated with the upper part of the shell 3 after being sequentially baffled by the four baffle plates 6.

The first medium can be a medium with a solid content within 15% such as garbage slurry and sewage, and the second medium is usually circulating water or other cleaning media.

Because the twenty heat exchange tubes 14 are connected in series to form a long heat exchange channel, the first medium can still fully exchange heat with the second medium in the shell 3 under the condition that the flow speed is relatively high in the flowing process of the first medium through the twenty heat exchange tubes 14, and the phenomenon that the flow speed of the first medium in the heat exchange tubes 14 can be reduced for full heat exchange to cause impurity deposition in the first medium, so that the heat exchange tubes 14 are blocked is avoided.

And when the chance has heat exchange tube 14 to be blockked up in the use, can dismantle the apron 1 at 3 both ends of casing, overhaul pipe 10 to intercommunication on each elbow pipe 9 is opened, and let in high-pressure liquid from first medium import pipe 15, observe which overhaul pipe 10 open end can't flow out liquid, can find out which section heat exchange tube 14 takes place to block up fast, then dismantle the elbow pipe 9 at this heat exchange tube 14 both ends, can dredge fast in inserting heat exchange tube 14 through special mediation ejector pin.

This device can carry out quick abundant heat transfer through the second medium that lets in heat transfer passageway that lets in a plurality of heat exchange tube 14 series formation and the casing 3 with first medium, avoids the heat transfer in-process first medium velocity of flow lower and take place to block up to when the chance meets the jam, the heat exchange tube 14 that is blockked up is gone out to quick the inspection of going up of the inspection pipe 10 on each elbow pipe 9 of accessible, thereby dredges it fast, has improved the efficiency of rubbish thick liquids heat transfer.

Above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be included in the protection scope of the present invention.
