Description

Technical Field

[0001] The present invention relates to the technical field of fuel cell detection, and in particular to a method and a device for automatically controlling temperature and humidity of a humidification system. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy, also known as an electrochemical generator. It is the fourth power generation technology after hydroelectric power generation, thermal power generation, and atomic power generation. Since fuel cells convert part of the Gibbs free energy in the chemical energy of the fuel into electrical energy through electrochemical reactions, they are not limited by the Carnot cycle effect and therefore have high efficiency. In addition, fuel cells use fuel and oxygen as raw materials and have no mechanical transmission parts, so they emit very little harmful gas and have a long service life.

[0003] During the fuel cell detection process, it is necessary to perform detection in a gas environment with relative temperature and humidity. In existing equipment, most gases use water mist sprayed from the nozzle for water heat exchange. The fuel cell condensate water heating technology is introduced to allow the condensate water to pass through the porous heat exchange plate to heat the gas, and an electric heating device is added to the gas outlet to heat the gas again to control the temperature. This method of generating fuel cell detection gas cannot meet the operating conditions of the fuel cell, and the temperature and humidity control accuracy is relatively poor, the temperature adjustment is relatively slow, and it is easy to contain a large amount of liquid water during the fuel cell humidification test. For this reason, we propose a humidification system temperature and humidity automatic control method and control device. Summary of the invention

[0004] The object of the present invention is to provide a method and a control device for automatically controlling temperature and humidity of a humidification system, so as to solve the problems that need to be solved in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for automatically controlling temperature and humidity of a humidification system, comprising the following steps:

[0006] A1: First, the deionized water stored in the humidification tank is pumped into the heater and cooling plate through a water pump. Then, the corresponding deionized water temperature is calculated according to the dew point temperature and relative humidity of the required gas. Then, the water temperature is jointly adjusted and stabilized by the heater and cooling plate.

[0007] A2: The deionized water after adjustment by the heater and the cooling plate is diverted to the fifth and sixth water pipes through the water diversion valve, and then the deionized water diverted through the fifth water pipe is transported to the inside of the humidification tank, and the deionized water diverted through the sixth water pipe is transported to the inside of the atomizing nozzle to form tiny droplets, and humidifies the gas through high-temperature gasification;

[0008] A3: The gas flow rate required for the test is controlled and delivered by a mass flow controller, and the delivered gas is diverted into two paths through a three-way valve. In the process of the three-way valve delivering the gas, the driving mechanism drives the sealing mechanism to move, so that the flow of the two groups of gas delivered and diverted through the first gas outlet cavity and the second gas outlet cavity can be controlled, and the regulating mechanism can be driven to move left and right during the up and down movement of the sealing mechanism. This movement method can control the gas flow rate of the inlet cavity of the three-way valve through one end of the regulating mechanism.

[0009] A4: One of the gases is transported to the inside of the diffuser in the humidification tank through the second gas pipeline. The gas passing through the diffuser undergoes bubbling, defoaming, atomization, humidification and deliquation to become saturated humidified gas, and then is transported to the inside of the mixer through the water separator at the top of the humidification tank and the fourth gas pipeline. The other gas is transported to the dry gas heating plate in the humidification tank through the third gas pipeline for heating, and is transported to the inside of the mixer through the fifth gas pipeline for mixing.

A method for automatically controlling temperature and humidity of a humidification system, characterized in that: The following steps are involved: A1: First, the deionized water stored in the humidification tank (1) is pumped into the heater (18) and the cooling plate (20) through the water pump (16), and then the corresponding deionized water temperature is calculated according to the dew point temperature and relative humidity of the required gas, and then the water temperature is jointly adjusted and stabilized by the heater (18) and the cooling plate (20); A2: The deionized water regulated by the heater (18) and the cooling plate (20) is diverted to the inside of the fifth water pipe (23) and the sixth water pipe (24) through the water diversion valve (22), and then the deionized water diverted through the fifth water pipe (23) is transported to the inside of the humidification tank (1), while the deionized water diverted through the sixth water pipe (24) is transported to the inside of the atomizing nozzle (25) to form tiny droplets, and is then gasified at high temperature to humidify the gas; A3: The gas flow rate required for the test is controlled and delivered by the mass flow controller (5), and the delivered gas is diverted into two paths through the three-way valve (7). In the process of the three-way valve (7) delivering the gas, the driving mechanism (32) drives the sealing mechanism (33) to move, so that the flow of the two groups of gas delivered and diverted through the first gas outlet cavity (36) and the second gas outlet cavity (37) can be controlled, and in the process of the sealing mechanism (33) moving up and down, the regulating mechanism (34) can be driven to move in the left and right directions. This movement method can control the gas flow rate of the gas inlet cavity (35) of the three-way valve (7) through one end of the regulating mechanism (34). This setting can use the sealing mechanism (33) and the regulating mechanism (34) to control the flow rate at the same time, so that the flow rate and flow rate of the gas can be accurately controlled; A4: One of the gases is transported to the inside of the diffuser (3) in the humidifying tank (1) through the second gas pipeline (8). The gas passing through the diffuser (3) undergoes bubbling, defoaming, atomization, humidification and liquid removal to become saturated humidified gas.

The two groups of gases transported by the fourth gas pipeline (11) and the fifth gas pipeline (12) are mixed through the mixer (10). The flow ratio of the two groups of gases can be calculated based on the relative humidity of the gas required for the test. The two flows are quickly diverted.
