Utility model content
This utility model purpose is the deficiency for solving above-mentioned technical problem, it is provided that the heat exchange of a kind of thermal source Multi-class propagation Device, can need to be divided into multistage according to technique and arrange all have fluid and the stream in tube bank in the cylinder shell of each heat-exchanging component Body heat exchange, a heat exchanger meets the duty requirements that can reach of multiple stage heat exchanger;Simultaneously can reduce thermal stress, it is to avoid flexibility The setting of element.
This utility model be the technical scheme is that the heat exchange of a kind of thermal source Multi-class propagation by the above-mentioned technical problem of solution Device, it is respectively arranged at two ends with left end bobbin carriage and right-hand member bobbin carriage;Multiple being sequentially connected with it is provided with between left end bobbin carriage and right-hand member bobbin carriage Heat-exchanging component, each heat-exchanging component is respectively provided with independent cylinder shell, and cylinder shell is provided with inlet tube and outlet, cylinder The two ends of shell are equipped with tube sheet, and the tube bank in each cylinder shell all connects with the tube sheet at its two ends, and adjacent cylinder Tube bank in shell is docked by tube sheet.
The deflection plate that be crisscross arranged is distributed in described cylinder shell.
Described deflection plate is fitted together by pull bar and distance sink tube with tube bank.
Tube bank in adjacent heat-exchanging component is fixed together by the securing member on tube sheet and gasket seal.
Described heat-exchanging component is preferably 3, including heat-exchanging component I, heat-exchanging component II and heat-exchanging component III.
The saddle of multiple sustainable heat-exchanging component it is provided with below described heat-exchanging component.
Below described heat-exchanging component, the quantity of set saddle, can be configured, preferably 1 according to actual needs.
Provide the benefit that:
1, the heat exchanger of this utility model thermal source Multi-class propagation, needs tube bank is divided into multistage according to technique;High temperature heat source Heat exchanger tube is entered, the tube bank in heat-exchanging component and the fluid heat transfer in the cylinder shell at its place by tube-side inlet.Pass through work Skill calculates length and the setting of deflection plate that can rationally arrange every section of tube bank, meets multi-state demand.Reach at one pipe Under journey operating mode, cylinder shell can have multiple heat-exchanging state, and its structure ensure that the cascade utilization of heat, improves energy profit Use efficiency.Can be widely applied in the industries such as oil, chemical industry, biological medicine, electric power, it is achieved the cascade utilization of thermal source.
2, the heat exchanger of this utility model thermal source Multi-class propagation, shares under a tube side, and multitubular bundles designs, and structure is tighter Gather, also save the bobbin carriage portion of material needed for multiple stage heat exchanger simultaneously, reduce manufacturing cost.Realize thermal source cascade utilization, Multi-stage heat exchanger, reduces heat source temperature and not the mating of temperature in shell side, reduction thermal stress, it is to avoid the setting of flexible member.
Accompanying drawing explanation
