Description

Technical Field

[0001] The utility model relates to the field of high-efficiency composite coolers, in particular to a corrosion-resistant wide-body composite cooler. Background Art

[0002] Existing split-type high-efficiency composite cooling equipment is widely used in the petroleum, chemical, petrochemical and other industries, but in actual application, there are problems such as high equipment manufacturing and transportation costs, a large number of welding joints for a single device, many interfaces with the customer's on-site system pipelines, excessive width for transportation, inconvenient internal maintenance, and uneven spraying of water in the evaporation section, which leads to many corrosion and scaling problems. Although some existing integrated composite cooling equipment has solved some on-site pipe orifice problems, the number of equipment modules is large, the production and assembly of parts are relatively complex, the production and processing are difficult and inefficient, and the material waste is serious, which does not meet the current social development needs. The layout of the heat exchange tube has problems such as uneven wind and water distribution, which poses a challenge to the durability of the equipment. After-sales problems are increasing, and the internal maintenance space is limited due to the complexity of the structure, making it difficult to maintain, which has also become a problem that cannot be ignored. In addition, the operating conditions in the fields of petroleum, chemical, petrochemical, etc. are diverse and complex, with many corrosive media, which also puts forward high requirements for the corrosion resistance of the equipment. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a corrosion-resistant wide-body composite cooler. Through the rational use of the flip tooling, the two-in-one frame is made possible, the deformation of the frame can be strictly controlled, and the scientific assembly method can significantly and effectively save materials, reduce production costs, reduce production processes, save manpower and material resources, and improve product production efficiency. It also reduces the equipment support frame, and the internal maintenance space is relatively sufficient, which is more convenient for equipment maintenance. The combined assembly of the inner wind shield, the outer wind shield, and the foam sealing plate reduces the influence of wind resistance, effectively increases the uniformity of the spray water, and reduces the occurrence of corrosion. The reasonable distribution of wind and water is directly beneficial to the service life of the heat exchange tube, the improvement of corrosion resistance, and the reduction of equipment failure rate. It is beneficial to the product market share and is a technical improvement for heat exchange composite cooling equipment.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a corrosion-resistant wide-body composite cooler, comprising a core frame, wherein the upper and lower ends of the front side of the core frame are respectively provided with inlet and outlet pipe boxes, and the inlet and outlet pipe boxes (4) at the upper and lower ends of the front side of the core frame are respectively provided as a water inlet box and a water outlet box, and the upper end of the core frame is evenly distributed with a water inlet pipe, and the front end of the water inlet pipe is correspondingly connected with the water inlet box, and the lower end of the core frame is evenly distributed with a precooling coil integrated heat exchange pipe, and a connecting pipe is provided between the rear end of the water inlet pipe and the water inlet of the precooling coil integrated heat exchange pipe, and the upper and lower ends of the connecting pipe are respectively connected with the water inlet pipe and the precooling coil integrated heat exchange pipe. The heat exchange tubes are connected through elbows, and the elbows between the upper and lower ends of the connecting tube and the water inlet pipe and the precooling coil integrated heat exchange tube are respectively arranged as a switching elbow and a coil elbow from top to bottom, and the water outlet of the precooling coil integrated heat exchange tube is correspondingly connected to the water outlet tank, and a water collector and a spray mechanism are arranged above the precooling coil integrated heat exchange tube from top to bottom. An inner wind shield plate is vertically arranged between the switching elbow and the coil elbow, and an outer wind shield plate is vertically arranged between the coil elbow and the lower end of the core frame, a foam sealing plate is arranged at the connection between the coil elbow and the precooling coil integrated heat exchange tube, and a flip tooling is arranged at the front and rear ends of the lower surface of the core frame.

[0005] Furthermore, the core frame includes a bottom frame, a top frame, and column supports, and the column supports are evenly distributed between the bottom frame and both sides of the fixed frame.

[0006] Furthermore, the flip tool is semicircular, and the arc surface of the semicircular flip tool faces the ground.

[0007] Working principle: Cancel the original multi-module core setting, and make a new heat exchange tube arrangement plan through re-process calculation. The multi-module core is integrated into one, and the whole upper box is designed to have only one heat exchange module, which successfully eliminates all the heat exchange tube gaps between the modules. Through rigorous force simulation analysis, the core frame is enlarged and widened, and the most suitable profile specifications are selected. The core frame can be used as a box frame for support. The support of all upper box components including the spray system, water collector and other parts is simplified and rooted in the core frame. The original upper box frame is cancelled, and the protective plate can be directly attached to the outside after the core is made. The arrangement of various baffles can make the wind and water evenly distributed, and solve the corrosion caused by the dead corner position of wind speed and spray distribution. Due to the inevitable flipping of the frame during the implementation of the two-in-one implementation, the normal hoisting of the module will cause the frame to deform. Therefore, it is necessary to develop a simple tooling suitable for flipping, which is specifically used for the flipping problem of such large modules.

[0008] The beneficial effects of the utility model are as follows: the core frame of the utility model can be used as the entire frame of the upper box, which greatly improves the material utilization rate; the arrangement of the heat exchange tubes is re-performed, and the whole set of equipment has now become a single-mode single-set, and the whole set of upper boxes only has a core of one module, breaking the limitation of the previous multi-module core. This change will directly help to eliminate the influence of the wind resistance between the multi-module heat exchange tubes, effectively utilize the heat exchange space, reduce the occurrence of heat exchange tube corrosion, and improve product performance; through force simulation calculation and analysis, the most suitable profile specifications are selected, and the core frame and the box frame are combined into one. The frame becomes larger and wider, and the original assembly method will cause the frame deformation to increase, which does not meet the product production requirements. The utility model reasonably utilizes the flip tooling to combine the two frames. First, it is possible to strictly control the deformation of the frame, and the scientific assembly method will significantly and effectively save materials, reduce production costs, reduce production processes, save manpower and material resources, and improve product production efficiency. It also reduces the equipment support frame, and the internal maintenance space is relatively sufficient, which is more convenient for equipment maintenance. The combined assembly of the inner wind shield, the outer wind shield, and the foam sealing plate reduces the impact of wind resistance, effectively increases the uniformity of the spray water, and reduces the occurrence of corrosion. The reasonable distribution of wind and water is directly beneficial to the service life of the heat exchange tube, improves the corrosion resistance, reduces the equipment failure rate, and is beneficial to the product market share. It is a technical improvement for heat exchange composite cooling equipment; the parts not introduced in detail in the utility model are existing common technologies.
