Abstract
The invention discloses a fast, steady and safe installation method of a baffle plate in a large-size heat exchanger. A heat exchanger barrel is horizontally placed so that an axis of the heat exchanger barrel is located in a horizontal plane; a lever is lifted by a hoisting apparatus and the length of the lever is two times more than the distance between an outlet of the heat exchanger barrel and the baffle plate which is the most far away from the outlet of the heat exchanger barrel; a lifting point of the hoisting apparatus is located on the middle point of the lever; one end of the lever is suspended with the baffle plate and the other end of the lever is suspended with a balancing weight with the same weight as the baffle plate; the baffle plate and the balancing weight are symmetrically distributed about the middle point of the lever; then the hoisting apparatus is moved and the baffle plate is stably moved towards the inner part of the heat exchanger barrel from the outlet of the heat exchanger barrel until the baffle plate is moved to an installation position; and after the baffle plate is fixed, the balancing weight is taken off and the lever is pulled out by utilizing the hoisting apparatus. The installation method of the baffle plate in the large-size heat exchanger has the advantage that the baffle plate can be stably and rapidly installed by utilizing a lever principle.
Description
Technical field
The present invention relates to the installation method of deflection plate in a kind of large heat exchanger.
Background technology
Along with the development of China's chemical industry to large-scale complexes, the equipment of chemical equipment industry also develops to high parameter, maximization, large-tonnage direction gradually at present.In order to respond the energy-saving and cost-reducing policy of country, the heat exchanger heat exchange area, the diameter that are adopted are also increasing simultaneously, and the heat exchanger of present domestic maximum has reached 30,000 square metres.When heat exchanger maximizes, also give to make to process and brought bigger difficulty, the for example wherein installation of deflection plate.The deflection plate size of large heat exchanger, weight are bigger, can't directly install by hand as little deflection plate.The installation of large heat exchanger deflection plate in the past is with chain block deflection plate to be hung in the inside of cylindrical shell, and gradually pulling in cylindrical shell again is until in place.Do the also effort of promptly taking a lot of work like this, and also lack guarantee at secure context.Take 6 deflection plates of 3.8 rice diameters to install for example, need 5 people just can install in 3 days, consumed great amount of manpower and material resources with said method.
Summary of the invention
Technical problem to be solved by this invention is: the installation method that deflection plate in a kind of quick, steady, safe large heat exchanger is provided.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the installation method of deflection plate in a kind of large heat exchanger, heat exchanger cylindrical shell horizontal positioned; Make the axis of heat exchanger cylindrical shell be positioned at horizontal plane, utilize the crane gear lever of slinging, the length of lever is greater than the exit of heat exchanger cylindrical shell and from the distance twice between the deflection plate farthest of heat exchanger cylindrical shell exit; And the suspension centre of crane gear is positioned at the midpoint of lever; One end of lever mounts deflection plate, and the other end mounts a balancing weight heavy with deflection plate etc., and deflection plate and balancing weight are about the mid point symmetrical distribution of lever; Move crane gear then; Deflection plate just moves to the heat exchanger barrel from the exit of heat exchanger cylindrical shell stably, moves to required installation site until deflection plate, treat that deflection plate fixes after; Take off balancing weight, utilize crane gear that lever is pulled out again.
The invention has the beneficial effects as follows: utilize lever principle, just can install stably, fast deflection plate.
Description of drawings
Fig. 1 is the structure chart of the present invention when deflection plate in the large heat exchanger is installed.
Among the figure: 1, heat exchanger cylindrical shell, 2, crane gear, 3, lever, 4, deflection plate, 5, balancing weight.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, the installation method of deflection plate in a kind of large heat exchanger, heat exchanger cylindrical shell 1 horizontal positioned; Make the axis of heat exchanger cylindrical shell 1 be positioned at horizontal plane; Utilize crane gear 2 lever 3 of slinging, the length of lever 3 is greater than the exit of heat exchanger cylindrical shell 1 and from the distance twice (guaranteeing to be positioned at the innermost deflection plate of heat exchanger cylindrical shell) between the deflection plate 5 farthest of heat exchanger cylindrical shell 1 exit, and the suspension centre of crane gear 2 is positioned at the midpoint of lever 3; One end of lever 3 mounts deflection plate 4; The other end mount one with heavy balancing weights 5 such as deflection plate 4, in order to save material, can be with the deflection plate of same size as balancing weight.Deflection plate 4 is symmetrically distributed with the mid point of balancing weight 5 about lever, utilizes lever principle, and deflection plate 4 is guaranteed a position stably.Move crane gear 2 then; Deflection plate 4 is just inner mobile to heat exchanger cylindrical shell 1 stably from the exit of heat exchanger cylindrical shell 1; Move to required installation site until deflection plate 4, just can fix deflection plate 4, treat that deflection plate 4 fixes after; Take off balancing weight 5, utilize crane gear 2 that lever 3 is pulled out again.When next deflection plate is installed, as long as install once more according to the method described above.
Advantage of the present invention is: utilize lever principle; Make deflection plate to sling stably; Move crane gear then and move deflection plate, in the immigration heat exchanger cylindrical shell that just can deflection plate is steady, quick, safe, the deflection plate in the most suitable installation large heat exchanger of said method.
Claims (1)
1. the installation method of deflection plate in the large heat exchanger, it is characterized in that: heat exchanger cylindrical shell horizontal positioned makes the axis of heat exchanger cylindrical shell be positioned at horizontal plane; Utilize the crane gear lever of slinging, the length of lever is greater than the exit of heat exchanger cylindrical shell and from the distance twice between the deflection plate farthest of heat exchanger cylindrical shell exit, and the suspension centre of crane gear is positioned at the midpoint of lever; One end of lever mounts deflection plate, and the other end mounts a balancing weight heavy with deflection plate etc., and deflection plate and balancing weight are about the mid point symmetrical distribution of lever; Move crane gear then; Deflection plate just moves to the heat exchanger barrel from the exit of heat exchanger cylindrical shell stably, moves to required installation site until deflection plate, treat that deflection plate fixes after; Take off balancing weight, utilize crane gear that lever is pulled out again.
