技术领域technical field
本实用新型是一种用于提高换热器交换效率的装置，特别是一种板式换热器温差稳定装置。The utility model relates to a device for improving the exchange efficiency of a heat exchanger, in particular to a temperature difference stabilizing device for a plate heat exchanger.
背景技术Background technique
板式换热器包括冷出管、热进管及冷进管、热出管，冷进管是连接在自来水管道上，热进管是连接高温废热源管道上。我们设定冷出管的温度为T2，热进管的温度为T1，热进管与冷出管的温差为T1-T2，在实际运行中，只有在温差T1-T2保持相对稳定的状态下，板式换热器才能具有较高的交换效率。由于冷进管是连接在自来水管道上，所以流量受各种因素影响，使冷出管和热进管的流量距设定值有很大偏差，进而导致温差T1-T2也随着变化，T1-T2的变化，将影响到板式换热器的交换效率。The plate heat exchanger includes a cold outlet pipe, a hot inlet pipe, a cold inlet pipe, and a hot outlet pipe. The cold inlet pipe is connected to the tap water pipe, and the hot inlet pipe is connected to the high-temperature waste heat source pipe. We set the temperature of the cold outlet pipe as T2, the temperature of the hot inlet pipe as T1, and the temperature difference between the hot inlet pipe and the cold outlet pipe as T1-T2. In actual operation, only when the temperature difference T1-T2 remains relatively stable , the plate heat exchanger can have a higher exchange efficiency. Since the cold inlet pipe is connected to the tap water pipe, the flow rate is affected by various factors, so that the flow rate of the cold outlet pipe and the hot inlet pipe has a large deviation from the set value, which in turn causes the temperature difference T1-T2 to change accordingly, and T1 The change of -T2 will affect the exchange efficiency of the plate heat exchanger.
发明内容Contents of the invention
本实用新型的目的是为了克服现有板式换热器冷出管与热进管的温差不稳定的缺陷，发明一种板式换热器温差稳定装置。The purpose of this utility model is to invent a temperature difference stabilizing device for a plate heat exchanger in order to overcome the defect that the temperature difference between the cold outlet pipe and the hot inlet pipe of the existing plate heat exchanger is not stable.
本实用新型的目的是按如下的方式来实现的：所述板式换热器温差稳定装置，包括一板式换热器，板式换热器的一侧设有冷出管和热进管，板式换热器的另一侧设冷进管和热出管，其特征在于：在冷出管上设有冷出温度传感器，其温度为T2，在热进管上设有热进温度传感器，其温度为T1，热进管上装置有变频水泵，另有一变频控制器，变频控制器通过电路与冷出温度传感器、热进温度传感器和变频水泵连接。The purpose of this utility model is achieved in the following manner: the temperature difference stabilizing device of the plate heat exchanger includes a plate heat exchanger, one side of the plate heat exchanger is provided with a cold outlet pipe and a heat inlet pipe, and the plate heat exchanger The other side of the heater is provided with a cold inlet pipe and a hot outlet pipe, which are characterized in that: a cold outlet temperature sensor is arranged on the cold outlet pipe, and its temperature is T2, and a heat inlet temperature sensor is arranged on the hot inlet pipe, and its temperature It is T1, the heat inlet pipe is equipped with a frequency conversion water pump, and another frequency conversion controller, the frequency conversion controller is connected with the cold outlet temperature sensor, the heat inlet temperature sensor and the frequency conversion water pump through a circuit.
本实用新型的积极效果如下：由于变频水泵的运行频率是根据T1-T2差值来决定，当T1-T2差值大于设定值时，变频水泵运行频率自动增加(转速提高，流量加大)，反之，当T1-T2差值小于设定值时，变频水泵运行频率自动减少(转速降低，流量减小)，这样热进管流量会随着冷出管流量的变化而自动变化，使T1-T2差值控制在设定范围内，冷出管和热进管的流量也达到基本平衡，流量平衡使板式换热器具有较高的交换效率。The positive effects of the utility model are as follows: Since the operating frequency of the variable frequency water pump is determined according to the T1-T2 difference, when the T1-T2 difference is greater than the set value, the operating frequency of the variable frequency water pump will automatically increase (speed increases, flow increases) , On the contrary, when the difference between T1-T2 is less than the set value, the frequency conversion water pump will automatically reduce the operating frequency (the speed will decrease, the flow rate will decrease), so that the flow rate of the hot inlet pipe will automatically change with the change of the flow rate of the cold outlet pipe, so that T1 The -T2 difference is controlled within the set range, and the flow of the cold outlet pipe and the hot inlet pipe has reached a basic balance. The flow balance makes the plate heat exchanger have a higher exchange efficiency.

具体实施方式Detailed ways
如图1所示，所述板式换热器温差稳定装置，包括一板式换热器1，板式换热器1的一侧设有冷出管2和热进管3，板式换热器1的另一侧设冷进管4和热出管5，其特征在于：在冷出管2上设有冷出温度传感器6，在热进管3上设有热进温度传感器7，热进管3上装置有变频水泵8，另有一变频控制器9，变频控制器9通过电路与冷出温度传感器6、热进温度传感器7和变频水泵8连接。As shown in Figure 1, the plate heat exchanger temperature difference stabilizing device includes a
运行过程如下：被要求热能回收的高温废热源从热进管进入，通过变频水泵、热进管温度传感器(T1)进入板式热交换器，与反向从冷进管进入的冷介质进行热能置换，由于板式热交换器的交换效率很高，交换后的高温废热源的热量被冷管介质充分吸收后变为常温从热出管排出，从冷进管进入的低温介质在吸收了高温废热源的热量后变为高温介质经冷出管温度传感器(T2)后流出，供生产或其它用途使用。The operation process is as follows: the high-temperature waste heat source required to recover heat energy enters from the heat inlet pipe, enters the plate heat exchanger through the frequency conversion water pump and the heat inlet pipe temperature sensor (T1), and performs heat energy replacement with the cold medium entering from the cold inlet pipe in the opposite direction , due to the high exchange efficiency of the plate heat exchanger, the heat of the exchanged high-temperature waste heat source is fully absorbed by the cold pipe medium and then becomes normal temperature and discharged from the heat outlet pipe, and the low-temperature medium entering from the cold inlet pipe absorbs the high-temperature waste heat source After the heat of the medium becomes high temperature, it flows out after passing through the temperature sensor (T2) of the cold outlet pipe for production or other purposes.
