Abstract
The invention discloses a kind of numeral temperature control heat-exchanger rig, it includes structure stainless steel casing, stainless steel inner container, heat exchanger tube, ring flange, water service pipe, temperature sensor, temperature controller, heater, industrial computer, the present invention utilizes industrial computer to regulate the bath temperature of heat-exchanger rig by the temperature value of bath temperature sensor: the method adopting continuous heating when temperature difference is bigger, the mode of PULSE HEATING is adopted to realize constant temperature when temperature is close to the constant temperature value preset, and because temperature sensor adopts digital temperature sensor in the present invention, the process of transmission is digital signal, for the temperature sensor that thermocouple and common analogue signal transmit, the problem being absent from line loss, reduce measurement error.
Description
Technical field
The present invention relates to the water quality stability of the recirculating cooling water system of the industries such as electric power, oil, chemical industry, metallurgy monitoring field, particularly relate to a kind of numeral temperature control heat-exchanger rig.
Background technology
Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial departments, occupies critical role aborning.In Chemical Manufacture, heat exchanger as heater, cooler, condenser, vaporizer and reboiler etc., can be more widely applied.Heat exchanger kind is a lot, but namely the principle and mode according to the exchange of cold and hot fluid heat substantially can divide three major types: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger application is at most.
Summary of the invention
The invention provides a kind of numeral temperature control heat-exchanger rig, including stainless steel inner container, stainless steel casing, heat exchanger tube, ring flange, pipe fitting, temperature controller, digital temperature sensor, industrial computer, heater, by using digital temperature sensor to induce temperature and the bath temperature of water inlet, and its digital signal is passed to industrial computer, by industrial computer, temperature controller is sent instruction to be heated, make the temperature of heat exchange tube fluid reach constant requirement.
In the present invention, stainless steel inner container is loaded in stainless steel casing, has thermal insulation layer between its outer wall and rustless steel inwall；Ring flange there is several hole confess for installing, enter the pipe fitting that water and heat transfer medium add, and be welded in stainless steel casing two ends；Digital temperature sensor is divided into inlet temperature sensor, outlet temperature sensor, bath temperature sensor, and wherein entrance, outlet temperature sensor are loaded on inlet tube and outlet respectively, and bath temperature sensor is arranged in thermal insulation layer；Heat exchanger tube, heater are positioned at inside stainless steel inner container, wherein the outlet on heat exchanger tube mounting flange and water inlet, and heater is fixed on inside ring flange, and electrically connects with temperature controller；Industrial computer electrically connects with temperature controller.
Preferably, digital temperature sensor is DS18B20；
Preferably, thermal insulation layer is filled with insulation material glass fibre cotton；
Preferably, the outlet in digital temperature sensor, inlet temperature sensor apart from its corresponding outlet, entrance distance less than 15cm；Industrial computer receives the digital signal of outlet, entrance, bath temperature sensor, and sends continuous heating, PULSE HEATING, stopping 3 kinds of instructions of heating by bath temperature sensor for temperature controller.
Due to entrance, what the temperature sensor of outlet and bath temperature detection adopted is digital temperature sensor DS18B20, detection temperature range is between-55 DEG C to+125 DEG C, minimum resolution is 0.0625 DEG C, it is entirely capable of meeting the requirement of detecting device 0.2 DEG C, and because of transmission process in be digital signal, for the temperature sensor that thermocouple and common analogue signal transmit, the problem being absent from line loss, reduce measurement error, and this temperature sensor is carried out initial alignment by producer when dispatching from the factory, so the scene that is made without again is demarcated and can directly be used；And between outer protective layer and inner bag, form thermal insulation layer can reduce aerial radiation loss, so this product has been provided simultaneously with accurate temperature controlling, reduce heat radiation, advantage easy to use.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram, in figure 1, heater 2, inlet temperature sensor 3, heat transfer medium add entrance 4, ring flange 5, thermal insulation layer 6, bath temperature sensor 7, temperature controller 8, stainless steel casing 9, heat exchanger tube 10, industrial computer 11, outlet temperature sensor 12, stainless steel inner container.
