Energy storage type industrial hot air blower

Abstract

The invention discloses an energy storage type industrial hot air blower. The energy storage type industrial hot air blower comprises a temperature control system, a machine shell, a first fan arranged in the machine shell, a heater and a heat storage device, wherein the shell is provided with an air inlet and an air outlet, the first fan is arranged in the air inlet, the heater is positioned in front of the first fan, the heat storage device is positioned in front of the heater, the heat storage device comprises a heat source, a shell and a heat storage material filling the shell, the heat source exchanges heat with the heat storage material to heat the heat storage material and store the heat, and cold air entering from the air inlet is heated through the heater and then is heated through the heat storage material so as to control the temperature of hot air at the air outlet. According to the energy storage type industrial hot air blower, the heat storage material is used for heatingthe heated air again, the temperature of the heat storage material is in the quasi-constant temperature zone based on the characteristic of the phase change temperature of the heat storage material,the temperature of the hot air at the air outlet is determined and controlled by means of the temperature of the heat storage material and the speed of the fans, and the target temperature can be corrected again; and on the basis of the heat storage characteristic of the heat storage material, the energy storage type industrial hot air blower has the energy-saving and energy-storage effects.

Description

technical field [0001] The invention relates to an industrial hot air blower, in particular to an energy storage type industrial hot air blower. Background technique [0002] Industrial hot air blowers are generally composed of fans, heaters and temperature control systems. Among them, the heater of the gas-fired industrial hot air blower is a gas burner, which is installed in the combustion chamber, and the cold air is heated by the burner combustion, and the hot air is formed by the rotation of the fan and sent out from the air outlet. The heater of the electric fan is an electric heater. The cold air is sent in by the fan from the air inlet, and heated by the electric heater to form hot air and sent out from the air outlet. The electric heater fan controls the power of the electric heater and the speed of the fan according to the temperature of the air outlet to achieve temperature regulation. [0003] But there are following defects in existing industrial hot air blowe...

Problems solved by technology

However, the sensor has the disadvantage of temperature detection hysteresis, that is, the actual temperature field has reached the temperature set by the system, but because the sensor has not detected it, the actuator continues to work, which causes the temperature field temperature to deviate from the set temperature within the lag time. Fixed value is getting bigger and bigger

[0005] (2) Some components of the temperature control system work in a relatively high ambient temperature, which will not only cause certain damage to the instruments and meters of the system, but also have a greater impact on the accuracy of temperature control, especially for the use of thermocouples for measurement. temperature sensor systems have a greater impact on the

[0006] (3) For the convenience of installation or the convenience of users using the temperature field, the temperature measurement sensors are mostly installed at the corners of the temperature field. For the uneven system with large temperature field, many openings or no circulation device, the temperature measurement sensor is used as the temperature measurement point Likely not representative to accurately reflect temperature conditions
