Description
Technical field
The present invention relates to technical field of heat exchangers, be specifically related to U-tube heat exchanger.
Background technology
Traditional U-tube heat exchanger, its structure includes: bobbin carriage and shell-side cylinder, the oral area of shell-side cylinder is fixedly installed shell flange, bobbin carriage is interval with tube sheet with shell flange, described Tube-sheet Welding is fixed on bobbin carriage, shell flange in shell-side cylinder is fixing with tube sheet to be connected, some pores are offered on tube sheet, U heat exchange bundle it is provided with in shell-side cylinder, on the deflection plate support that described U heat exchange bundle is fixedly supported in shell-side cylinder, deflection plate support can slide in shell-side cylinder, the pipe end of U heat exchange bundle wears, and be fixed in the pore of tube sheet.U heat exchange bundle in U-tube heat exchanger needs periodic inspection and cleaning, it is therefore desirable to pulled out in shell-side cylinder by U heat exchange bundle.Traditional method is that shell-side cylinder maintains static, by lifting machinery, bobbin carriage is pulled outward, it is connected as a single entity owing to bobbin carriage, tube sheet, U-shaped heat-exchanging tube bundle and deflection plate support are fixing, therefore bobbin carriage is pulled outwardly and tube sheet, U-shaped heat-exchanging tube bundle and deflection plate support will be driven to be displaced outwardly together, thus can be to operations such as the U heat exchange Shu Jinhang maintenance removed outside shell-side cylinder, cleanings.But owing to the weight of bobbin carriage and U heat exchange bundle is big, it is necessary to use lifting machine to be pulled out by U heat exchange bundle, the most not only cause maintenance and disposal costs high, and cause maintenance and cleaning work loaded down with trivial details.
Summary of the invention
It is an object of the invention to: a kind of U-tube heat exchanger that can significantly facilitate maintenance and cleaning work is provided.
nullFor achieving the above object，The technical solution used in the present invention is: U-tube heat exchanger，Including: bobbin carriage and shell-side cylinder，The oral area of shell-side cylinder is fixedly installed shell flange，Bobbin carriage is interval with tube sheet with shell flange，Described Tube-sheet Welding is fixed on bobbin carriage，Shell flange in shell-side cylinder is fixing with tube sheet to be connected，Some pores are offered on tube sheet，U heat exchange bundle it is provided with in shell-side cylinder，On the deflection plate support that described U heat exchange bundle is fixedly supported in shell-side cylinder，Deflection plate support can slide in shell-side cylinder，The pipe end of U heat exchange bundle wears、And be fixed in the pore of tube sheet，The bottom of shell-side cylinder is provided with shell-side cylinder saddle，The bottom of shell-side cylinder saddle is provided with roller，On described roller supporting guide rail on the ground，It is provided with bottom tube sheet circumference and is supported on ground tube bundle support saddle.
Further, aforesaid U-tube heat exchanger, wherein, the forward and backward two-end part bottom shell-side cylinder is respectively arranged with shell-side cylinder saddle, each shell-side cylinder saddle base is provided with a pair roller, and a pair roller of each shell-side cylinder saddle base is supported in the pair of guide rails on ground respectively.
Further, aforesaid U-tube heat exchanger, wherein, the structure of described shell-side cylinder saddle includes: the circular arc gripper shoe adapted with shell-side cylinder, and the bottom of circular arc gripper shoe is provided with saddle bracing frame.
The invention have the advantage that and can easily shell-side cylinder outwards be removed, make U heat exchange bundle exposed outside, thus greatly facilitate maintenance and the cleaning work of U heat exchange bundle, reduce the maintenance of U heat exchange bundle and the cost of cleaning work, also substantially increase the maintenance of U heat exchange bundle and the efficiency of cleaning work.
Accompanying drawing explanation
Fig. 1 is the structural representation of U-tube heat exchanger of the present invention.
Fig. 2 is the structural representation of the shell-side cylinder saddle shown in left view direction in Fig. 1.
Detailed description of the invention
The present invention is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
nullSuch as Fig. 1、Shown in Fig. 2，U-tube heat exchanger，Including: bobbin carriage 1 and shell-side cylinder 2，The oral area of shell-side cylinder 2 is fixedly installed shell flange 3，Bobbin carriage 1 is interval with tube sheet 4 with shell flange 3，Described tube sheet 4 is weldingly fixed on bobbin carriage 1，Shell flange 3 in shell-side cylinder 2 is bolted to connection with tube sheet 4，Some pores are offered on tube sheet 4，U heat exchange bundle 5 it is provided with in shell-side cylinder 2，U heat exchange bundle 5 is fixedly supported on the deflection plate support 6 in shell-side cylinder 2，Deflection plate support 6 can slide in shell-side cylinder 2，The pipe end of U heat exchange bundle 5 wears、And be fixed in the pore of tube sheet 4，The bottom of shell-side cylinder 2 is provided with shell-side cylinder saddle 7，In the present embodiment bottom shell-side cylinder 2 before、Rear two-end part is respectively arranged with shell-side cylinder saddle 7，The bottom of each shell-side cylinder saddle 7 is provided with a pair roller 8，A pair roller 8 bottom each shell-side cylinder saddle 7 is supported in the pair of guide rails 9 on ground respectively.In the present embodiment, the structure of shell-side cylinder saddle 7 includes: the circular arc gripper shoe 11 adapted with shell-side cylinder 2, and the bottom of circular arc gripper shoe 11 is fixedly installed saddle bracing frame 10.It is provided with bottom tube sheet 4 circumference and is supported on ground tube bundle support saddle 12.
nullUsing method is as follows: when needs are to the maintenance of U heat exchange Shu Jinhang or cleaning，Release the connection between shell flange 3 and tube sheet 4，Pull out shell-side cylinder 2，On the one hand owing to being provided with roller 8 on the shell-side cylinder saddle 7 bottom shell-side cylinder 2，On the other hand it is far smaller than bobbin carriage 1 due to the deadweight of shell-side cylinder 2、The weight of the parts such as U heat exchange bundle 5 and deflection plate support 6 because of，These need easily pull shell-side cylinder 2，Roller 8 bottom shell-side cylinder 2 will slide in and out on guideway，Under the support of tube bundle support saddle 12，Tube sheet 4、U heat exchange bundle 5 and bobbin carriage 1 parts such as grade are stably supported on the ground，So shell-side cylinder 2 is constantly displaced outwardly，U heat exchange bundle 5 will progressively exposed outside，Such that it is able to U heat exchange bundle 5 is overhauled、The work such as cleaning.
Use the U-tube heat exchanger of said structure, easily shell-side cylinder 2 outwards can be removed, make U heat exchange bundle 5 exposed outside, thus greatly facilitate maintenance and the cleaning work of U heat exchange bundle 5, greatly reduce the maintenance of U heat exchange bundle 5 and the cost of cleaning work, also substantially increase the maintenance of U heat exchange bundle 5 and the efficiency of cleaning work.
