Embodiment Construction

[0024] see figure 1 , illustrating the first embodiment of the method for monitoring the heat recovery efficiency of the oven provided by the present invention, including performing the following steps S1 to S3 in sequence:

[0025] Step S1: Heat recovery from the oven using an economizer.

[0026] see figure 2 , indicating that the oven 10 has an air inlet 14 and an exhaust outlet 13, the high-temperature exhaust gas in the heating chamber 11 of the oven 10 is discharged to the outside through the exhaust outlet 13, and the ambient temperature air from the outside is introduced into the oven 10 through the air inlet 14 . The exhaust port 13 and the air inlet 14 of the oven 10 are respectively connected to an economizer 20 in implementation, so that the high-temperature waste gas in the heating chamber 11 of the oven 10 is discharged to the outside through the economizer 20, and the normal temperature air outside It is introduced into the heating chamber 11 of the oven 10 ...

Abstract

The invention provides a method for monitoring the heat recovery efficiency of an oven, which comprises the following steps of: performing heat recovery on high-temperature waste gas discharged by the oven by using an energy saver, and detecting the temperature of the high-temperature waste gas in the oven before the high-temperature waste gas is introduced into the energy saver so as to obtain an in-furnace temperature; the temperature of the normal-temperature air before the normal-temperature air is guided into the oven through the energy saver is detected to obtain an air inlet temperature, the temperature of the normal-temperature air before the normal-temperature air is guided into the energy saver is detected to obtain an environment temperature, and the heat recovery efficiency is calculated according to the environment temperature. The invention further comprises a monitoring device for implementing the method, so that the problem that a user cannot know the energy-saving effect of the oven after the energy saver is configured is solved.

Description

technical field [0001] The invention relates to a temperature monitoring technology of an oven, in particular to a method and a device for monitoring the heat recovery efficiency of an oven. Background technique [0002] The oven targeted by the present invention refers to an industrial oven, which has been widely used in the baking operation of existing optoelectronic products such as PCB, LCD or touch panel (Touch Panel), and can perform drying processing or aging of the above optoelectronic products Tests and other operations; traditional industrial ovens generally have a heating chamber and a heater (such as an electric heating tube) located at the end of the heating chamber, which can be adjusted and controlled by generating heat through the heater The interior of the heating chamber reaches the expected heating temperature, and then bakes the above-mentioned photoelectric products; during this period, the outside air with a normal temperature of about 10 to 40 degrees ...
