Abstract
The utility model discloses a kind of digital temperature control heat-exchanger rig, it comprises structure stainless steel casing, stainless steel inner container, heat exchanger tube, ring flange, water service pipe, temperature sensor, temperature controller, heater, industrial computer, the utility model 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 larger, when temperature realizes constant temperature close to adopting the mode of PULSE HEATING during the constant temperature value preset, and because temperature sensor adopts digital temperature sensor in the utility model, data signal in the process of transmission, for the temperature sensor that thermocouple and common analog signal transmit, there is not the problem of line loss, reduce measure error.
Description
Technical field
The utility model relates to the water quality stability monitoring field of the recirculating cooling water system of the industries such as electric power, oil, chemical industry, metallurgy, particularly relates to a kind of digital temperature control heat-exchanger rig.
Background technology
Heat exchanger is the common apparatus of chemical industry, oil, power, food and other many industrial department, occupies critical role aborning.In Chemical Manufacture, heat exchanger can be used as heater, cooler, condenser, evaporimeter and reboiler etc., applies more extensive.Heat exchanger kind is a lot, but substantially can divide three major types namely according to the principle of cold and hot fluid exchange heat and mode: dividing wall type, hybrid and heat accumulating type.In three class heat exchangers, dividing wall type heat exchanger application at most.
Utility model content
The utility model provides a kind of digital temperature control heat-exchanger rig, comprise stainless steel inner container, stainless steel casing, heat exchanger tube, ring flange, pipe fitting, temperature controller, digital temperature sensor, industrial computer, heater, by the temperature and the bath temperature that use digital temperature sensor to induce water inlet, and by its digital signal transfers to industrial computer, send instruction by industrial computer to temperature controller to heat, make the requirement that the temperature of heat exchanger tube inner fluid reaches constant.
In the utility model, stainless steel inner container is loaded in stainless steel casing, has thermal insulation layer between its outer wall and stainless steel inwall; Ring flange there is several hole confess for installing, entering 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 stainless steel inner container inside, the delivery port wherein on heat exchanger tube mounting flange and water inlet, and heater is fixed on inside ring flange, and is electrically connected with temperature controller; Industrial computer is electrically connected with temperature controller.
Preferably, digital temperature sensor is DS18B20;
Preferably, thermal insulation layer is filled with insulation material glass fibre cotton;
Preferably, the distance of the outlet in digital temperature sensor, inlet temperature sensor outlet corresponding to it, entrance is no more than 15cm; Industrial computer receives the data signal of outlet, entrance, bath temperature sensor, and send continuous heating by bath temperature sensor for temperature controller, PULSE HEATING, stopping heat 3 kinds of instructions.
Due to entrance, what the temperature sensor that outlet and bath temperature detect adopted is digital temperature sensor DS18B20, detected temperatures scope is between-55 DEG C to+125 DEG C, minimum resolution is 0.0625 DEG C, the complete requirement that can meet checkout gear 0.2 DEG C, and because of transmission process in be data signal, for the temperature sensor that thermocouple and common analog signal transmit, there is not the problem of line loss, reduce measure error, and this temperature sensor carries out initial alignment by producer when dispatching from the factory, again demarcate can directly use so do not need to carry out scene, and between outer protective layer and inner bag, form thermal insulation layer can reduce aerial radiation loss, so this product has possessed accurate temperature controlling simultaneously, reduce heat radiation, advantage easy to use.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation, and 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.
