Description
Technical field
The present invention relates to a kind of temperature to control and off gas system, particularly relate to a kind of blood purification temperature and control and off gas system.
Background technology
Current blood purification temperature controls and off gas system, main control mode is be provided with one in the water side of heater from the temperature sensor close to heater outlet and one from the distant temperature sensor of heater outlet, pass through control heater, make the temperature value reaching setting from the temperature sensor that heater is distant, only use as monitoring from the temperature sensor close to heater outlet is general, because another temperature sensor is away from heater, so the hysteresis quality of whole heating system is very large, if firing rate requires very fast, the overshoot value of the temperature of heating can be made larger, otherwise, firing rate is comparatively slow and unstable once discharge, temperature fluctuation can be very large.Also have a kind of mode of less use, by heater, indirectly heat the water inside pipeline, it can not produce water route and pollute, but due to its indirect temperature measurement accuracy lower, and during heating, thermal inertia is very large, causes temperature control precision lower.
Therefore those skilled in the art are devoted to develop a kind of blood purification temperature that can respond fast and control and off gas system.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of blood purification temperature that can respond fast and controls and off gas system.
For achieving the above object, the invention provides a kind of blood purification temperature and control and off gas system, comprise inlet water tank; Described inlet water tank has water inlet; The outlet of described inlet water tank is connected with the water inlet of heater by pipeline; The outlet of described heater is connected with water tank; The first temperature sensor is provided with in pipeline between described heater and described water tank; The described outfan of the first temperature sensor is connected with the first input end of heating control circuit; The second temperature sensor is provided with in pipeline between the outlet of described inlet water tank and described heater water inlet; The outfan of described second temperature sensor is connected with the second input of described heating control circuit; The outfan of described heating control circuit exports control signal to described heater, controls the heating element generates heat of described heater.
Preferably, the air vent of described water tank is connected with the air inlet of described inlet water tank; Described inlet water tank is provided with air vent; Also gear pump is provided with between described inlet water tank and heater; Also choke valve is provided with in pipeline between described inlet water tank and described gear pump.
Preferably, described heater is also provided with temperature relay; One end of described temperature relay is connected with described heater, and the other end of described temperature relay is connected with described heating control circuit.

Fig. 1 is the structural representation of the embodiment of the present invention one.
Fig. 2 is the structural representation of the embodiment of the present invention two.
Fig. 3 is the structural representation of the embodiment of the present invention three.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: as shown in Figure 1, a kind of blood purification temperature controls and off gas system, it is characterized in that: comprise inlet water tank 1; Described inlet water tank 1 has water inlet; The outlet of described inlet water tank 1 is connected by the water inlet of pipeline with heater 2; The outlet of described heater 2 is connected with water tank 3; Two the first temperature sensors 5 are provided with in pipeline between described heater 2 and described water tank 3; The outfan of described first temperature sensor 5 is connected with the first input end of heating control circuit 6; The second temperature sensor 7 is provided with in pipeline between the outlet of described inlet water tank 1 and described heater 2 water inlet; The outfan of described second temperature sensor 7 is connected with the second input of described heating control circuit 6; The outfan of described heating control circuit 6 exports control signal to described heater 2, and the heating element heater 8 controlling described heater 2 generates heat.
First temperature sensor 5 and the second temperature sensor 7 are thermistor temperature sensor, described heater 2 is tubular container, heater 2 is provided with outlet and water inlet, heating element heater 8 is arranged in heater 2, described heating element heater 8 is heating rod, certainly, the first temperature sensor 5 and the second temperature sensor 7 can be arranged according to demand, are such as set to three.
Reverse osmosis water in heating element heater 8 pairs of heaters carries out heat treated, described second temperature sensor 7 gathers the temperature of heater 2 water inlet reverse osmosis water and sends heating control circuit 6 to, first temperature sensor 5 gathers the temperature of heater 2 outlet and sends heating control circuit 6 to, the temperature value that described heating control circuit 6 collects according to the first temperature sensor 7 and the second temperature sensor 5, calculates by pid algorithm the power that the output of heating element heater 8 and heating element heater 8 make the temperature value of heater 2 outlet up to standard; Heating control circuit 6 adjusts the output of heating element heater 8, makes the temperature of heater 2 outlet reach the temperature value of setting.
Embodiment two: as shown in Figure 2, the structure of the present embodiment is substantially identical with embodiment one, and difference is: the air vent 12 of described water tank 3 is connected with the air inlet of described inlet water tank 1; Described inlet water tank 1 is provided with air vent 4; Gear pump 9 is also provided with between described inlet water tank 1 and heater 2; Choke valve 10 is also provided with in pipeline between described inlet water tank 1 and described gear pump 9.
Reverse osmosis water is extracted out and is entered heater 2 through choke valve 10 by gear pump 9 from inlet water tank 1, owing to being subject to the effect of choke valve 10, minute bubbles in reverse osmosis water pool larger bubble under the effect of negative pressure, reverse osmosis water enters after heater 2 heats and arrives water tank 3 through the first temperature sensor 5, because the density of the density ratio reverse osmosis water of bubble is little, so bubble can get back to inlet water tank 1 from the air vent 12 of water tank 3, then bubble is discharged by the air vent 4 of inlet water tank 1.
Embodiment three: as shown in Figure 3, the structure of the present embodiment is substantially identical with embodiment two, and difference is: described heater 2 is also provided with temperature relay 11; One end of described temperature relay 11 is connected with described heater 2, and the other end of described temperature relay 11 is connected with described heating control circuit 6.
When heater 2 temperature exceedes setting value, temperature relay 11, by the dump of heater 2, stops heater 2 to continue heating.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technical staff in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment.
