Trichlorosilane double condenser tube plate structure and Expansion and Tubes


Degree related, according to Equation 1 and Figure 3 for a field expansion rod 2 3l 3,[link widoczny dla zalogowanych], a hub of a heat exchange is not difficult to export its relationship to: 1:-2Wt + (-Dd) 2t (2) ga ... where I shot an expansion the insertion depth, mm; d before the diameter of a pipe expansion, mm; t a pipe wall thickness, mm; a shot of a half angle expansion, mm; D a plate diameter, mm; w an Expanding rate. Expander is chosen, the expansion rod is a semi-cone angle of a fixed value, so the spin precession depends on the depth of an inflation hole before the tube and tube plate gap between the Q (Dd), pipe wall thickness t w and the Expanding Rate rate is chosen as long as the expander, I can be obtained by Equation 2. Therefore, any expansion joint, despite the gap, the wall thickness varies, as long as the control rod insertion depth expansion, the expander can guarantee the same rate. We will control board aperture, the tube diameter and wall thickness measurement with a dial indicator to group after matching, each tube and tube sheet are relatively close to the hole size; then calculated for each group of type 2 rod insertion depth expansion I mean, and make corresponding marks around pores; the last turn Expansion in groups, the first expansion inside the tube plate, and then the outer tube sheet expansion. Expanded After sampling dozens of different parts of the pore, calculated by measuring the actual expander rate control between 5.5 to 7. After the condenser's first made in 1990 officially put into use in early 1O, and then they have produced four. Five equipment operation so far, have not found any leaks, and all the normal chemical heat pump technology energy saving equipment, chemical equipment, heat pump technology of alumina Gen Shanghai Petrochemical Company 7. A /, /, L describes the type of chemical heat pump, working principle and thermal efficiency, and to present several applications have been developed for a chemical heat pump described in more detail to know. Keywords blue Ramie Ramie Mexican League 1 Introduction Section A,[link widoczny dla zalogowanych], the chemical industry involves many sectors, its products and more wide use, production, energy consumption is higher in the national economy sector. Energy efficiency is not high, however,[link widoczny dla zalogowanych], a considerable part of the energy as waste heat into the unused and the environment, and therefore the recycling of waste heat caused great concern about workers. In recent years, countries are working to develop waste heat power generation, compression heat pump, absorption heat pump and other energy-saving technologies, some of which have been practical. However, the low temperature waste heat, waste water and the situation unstable and there is a change of energy recovery is still a difficult problem to solve. In order to effectively capture and use energy, heat storage and heat pumps are the two essential technologies. Storage technology is to heat up their savings, only when needed to release the necessary amount of technology; the heat pump is based on low-temperature waste heat to generate high temperature heat source technology. This paper describes the chemical heat pump is a heat energy is converted to chemical energy and heat pumps will heat storage function into one function with the new energy-saving technology devices. It has a heat storage, heat transport and many other advantages, it can serve as good heat-driven heat pump. Since this type of multi-reaction system, so it may be widely used. The emergence of this technology, with its efficient heat storage and the use of low-grade waste heat caused by people upgrading attention. According to the U.S. energy report describes the petrochemical industry, chemical industry, pulp industry, the economic effects of the use of chemical heat pump for the annual energy 2 �� lO \for the chemical energy of the device, it relies on the state of chemical reaction using chemical endothermic and exothermic changes. In these reactions (both reversible reaction) in order to make changes at low temperature under the heat absorption, while at high temperatures to complete its reversible exothermic change,[link widoczny dla zalogowanych], the need for participation in the process of heat (see Figure 1). in the heat engine and heat pump question the existence of common substances, such substances in the process of heat by compression, in the form of concentrated heat pump system to transfer power 0]. Select the appropriate chemical reaction cycle and the reaction conditions of 4 Conclusion 4.1 condenser for trichlorosilane alone when the two heat transfer media, the material produced only slight corrosion. with double tube sheet structure to prevent leakage due to mixed media corrosion caused by the strong, for extending its life, the effect is significant. 4.2 The group structure was improved overall processing of dual-welded plate and ordinary double tube sheet, compared with the processing of convenience, high concentric pore, through tube easy, Expansion joints and good quality. 4.3 Expansion require a higher heat exchanger, when the lack of reliable data, based on the use of heat conditions,[link widoczny dla zalogowanych], simulation tests, to determine more appropriate Expander rate or swelling degrees. 4.4 mechanical roller expander can be used for low-pressure twin-tube heat exchanger of the deep hole expander, as long as a reasonable choice, and strictly control the swelling degree expander rate or can be obtained quite satisfactory effect.
