Abstract
The utility model relates to a heat pipe-type heater for a sulfur smelting groove used in a sulfur acid making process. The heat pipe-type heater is mainly characterized in that the lower part of the housing of the heater is divided by a pipe plate, so as to form an air-proof cavity; the lower end of a heat conducting element heat pipe penetrates into the pipe plate and is placed into the cavity; and the cavity is connected with an external heat source inlet, condensed water or a flue gas outlet respectively. The heat pipe-type heater is designed according to the unique performance of liquid sulfur that the viscosity changes with temperature. According to the isothermal performance of the heat pipe, that is, the temperature difference of a working medium in the heat pipe is very low during phase change and flowing in the heat transmission process, the defect in the prior art that the temperature gradient of steam in a coil heater is large during flowing, heat transmission and condensation is overcome. Therefore, the heat pipe-type heater has the advantages of low energy consumption, high sulfur smelting efficiency, long equipment service life and the like.
Description
Technical field
The utility model relates to the well heater of sulfur melting groove in a kind of acid production with sulphur technology.
Background technology
China's acid production with sulphur sulfur melting groove well heater nearly all is the steam coils well heater at present.Because the viscosity of liquid-state sulfur has temperature variant peculiar property, promptly temperature is raised to 155 ℃ of its viscosity from 115 ℃ to be reduced to 0.0065Pa.S gradually minimum, but temperature rises from 155 ℃ again, and viscosity raises again on the contrary gradually.Be controlled at 145～155 ℃ for best according to this characteristic temperature in molten sulphur process.Because of steam coils well heater heat exchange thermograde is big, the coefficient of heat transfer is little, and in use heat transfer tube is prone to fouling, and work-ing life is short, often all will change again every year, not only influences production but also increase factory cost, causes waste; As long as and have heat transfer tube to leak aborning will to bleed steam water in the sulphur, must stop production to overhaul; Its thermal source can only be used water vapour.The steam coils well heater also exists the well heater volume big, deficiencies such as heat exchange weak effect.
Summary of the invention
The purpose of the utility model provides the heat pipe-type sulfur melting groove well heater that low, the molten sulphur efficiency of a kind of energy consumption is high, service life of equipment is long.
The technical scheme of the utility model is achieved in that well heater housing bottom is divided into airtight cavity mutually through tube sheet; The lower end of heat conducting element heat pipe is passed tube sheet and is inserted in this cavity, and this cavity is connected with external thermal source import, water of condensation or exhanst gas outlet respectively.
The utility model well heater housing top is unenclosed construction.
Described unenclosed construction is that well heater housing top is the support type structure, and promptly well heater housing top just plays a supportive role.
The utility model is the heat pipe sulfur melting groove well heater that the viscosity according to liquid-state sulfur has temperature variant peculiar property to design.The utility model utilizes the isothermal characteristics of heat pipe; Its phase transformation in the phase-change heat transfer process of instant heating plumber matter, this all very little isothermal characteristics of the temperature difference when flowing overcome spiral heater steam big shortcoming of thermograde when flowing heat transfer, condensation of prior art.
During use, several the utility model are fixed in the sulfur melting groove, establish whisking appliance in the middle of the sulfur melting groove.The utility model carries out calculation Design with the discrete type method of calculation.The total heat transfer coefficient of the utility model is twice above than coil tube type, save steel about 30% than shell-and-tube heater; Utilize that heat pipe evaporator section is different with the condensation segment heat transfer coefficient confirms heat interchanging area and length dimension, flexible design; The utility model separates with tube sheet because of in the middle of heating zone and the condensation segment, and cold and hot two fluids are separated from each other, and when a certain heat pipe leaks, can not influence production, and the bleed incident of sulphur of steam, water can not take place yet; The tube plate structure that the utility model adopts pipe and housing to support each other replaces traditional flat head structure, and structure is simpler.
The utility model can adapt to and use steam or sulfuric acid tail gas waste heat to be thermal source under the prerequisite of structure that does not change former sulfur melting groove body and structure, fast melting solid sulphur.Having the molten sulphur operation that makes acid production with sulphur cuts down the consumption of energy, practices thrift cost, improves molten sulphur efficiency, increases the service life, advantages such as while fume afterheat capable of using.
Description of drawings
The embodiment that will combine accompanying drawing to provide below further details the utility model.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Among Fig. 1; Establish water steel heat pipe (9) in the well heater housing (1) as heat transfer element; Through tube sheet (3) well heater being divided into two sections is heating zone (2) and condensation segment (4); The closed cavity that well heater housing (1) bottom is divided into through tube sheet (3) mutually is heating zone (2); The lower end of heat conducting element heat pipe (9) is passed tube sheet (3) and is inserted in this cavity, and this cavity is connected with external thermal source import, water of condensation or exhanst gas outlet respectively, utilizes the evaporator section of external thermal source opposite heat tube (9) to heat.The condensation segment (4) on well heater housing (1) top is a unenclosed construction, and the outside housing of condensation segment (4) is the fence type supporting structure.Be connected to external thermal source import (8), relief valve connection (7) and water of condensation or exhanst gas outlet (6) on well heater housing (1) the upper end cover plate (5); Steam or flue gas are placed the heat pipe (9) in the heating zone (2) through external thermal source import (8) importing heating zone (2) heating, and the sulphur of passing to heat outside the condensation segment (4) through heat pipe (9) makes it be molten into liquid.Water of condensation or flue gas are discharged from water of condensation or exhanst gas outlet (6).
Among Fig. 2, be connected to external thermal source import (8), relief valve connection (7) and water of condensation or exhanst gas outlet (6) on the utility model housing upper end cover plate (5).
