Embodiment 1

[0033] Such as figure 1 , figure 2 As shown, this embodiment provides a furnace temperature measuring device for a waste incinerator, the center of the top of the furnace is provided with a first infrared thermal imager 1 that can rotate 360 ​​degrees in a horizontal plane, and can look down on the entire furnace, and vertically view it from multiple angles. Measure the temperature in the furnace; the joints between the four walls inside the furnace are each equipped with a second infrared thermal imager 2 that can move longitudinally in the furnace, and each second infrared thermal imager adopts a dynamic sealing method, not only It can ensure that the temperature in the furnace will not be lost, and it can also move and monitor the temperature of each height area in the furnace in real time, realizing the measurement of the transverse temperature on different height sections of the furnace; each of the four walls of the main combustion area in the furnace is equipped with a...

Embodiment 2

[0039] Such as image 3 As shown, this embodiment provides a furnace temperature control system using the furnace temperature measuring device of the waste incinerator in Embodiment 1, including the furnace temperature measuring device of the waste incinerator, a multi-loop temperature control system, an alarm system and a learning system. Among them, the furnace temperature measuring device of the garbage incinerator is used to detect the temperature in the furnace of the garbage incinerator, and feed back the obtained temperature data to the multi-loop temperature control system.

[0040] The multi-loop temperature control system is used to adjust the furnace temperature of the garbage incinerator by adjusting the operating parameters of the garbage incinerator. It includes a main loop and a secondary loop, and each loop has a different function of adjusting the furnace temperature of the garbage incinerator. parameter.

[0041] The alarm system is used to send an alarm whe...

Embodiment 3

[0044] Such as image 3 , Figure 4 As shown, this embodiment provides a furnace temperature control method using the furnace temperature control system of Embodiment 2, and the main steps are as follows:

[0045] S1. The furnace temperature measuring device of the garbage incinerator detects the temperature in the furnace of the garbage incinerator, and feeds back the obtained temperature data to the temperature control system;

[0046] S2. The temperature control system compares the obtained temperature data with the preset temperature range value, if the temperature data is outside the preset temperature range value, adjust the use parameters of the waste incinerator so that the temperature in the furnace can be adjusted within the preset temperature range; if the temperature in the furnace cannot be adjusted accurately within the preset time, an alarm will be issued to manually adjust the operating parameters of the waste incinerator.

[0047] Wherein, the temperature co...

Abstract

The invention provides a garbage incinerator combustion chamber temperature-measuring device. A rotatable first infrared thermal imaging instrument is disposed at the top of the interior of a combustion chamber; movable second infrared thermal imaging instruments are disposed on all the wall surfaces of the interior of the combustion chamber correspondingly; and a plurality of thermocouples are disposed on the inner wall surfaces of a main combustion section area of the combustion chamber. The invention further provides an incinerator temperature control system and an incinerator temperature control method correspondingly. By means of the garbage incinerator combustion chamber temperature-measuring device and the system provided by the invention, the temperatures of the transverse layers in all the heights inside the combustion chamber can be detected in real time, the longitudinal temperature inside an incinerator can be detected, omni-directional detection of the temperature inside the incinerator is achieved, and distribution of a temperature field in the incinerator is accurately restored; and through the corresponding incinerator temperature control method, adjustment of the incinerator temperature is fast and effective, the incinerator temperature can be stabilized within a reasonable range, and optimization of the combustion process is achieved.

Description

technical field [0001] The invention relates to the technical field of temperature measurement and control, in particular to a furnace temperature measuring device for a garbage incinerator, a furnace temperature control system and a method. Background technique [0002] The incineration treatment of municipal solid waste has the characteristics of complete harmlessness, obvious reduction in volume and weight, and easy realization of resource utilization. It has been widely used in my country in recent years. Through the analysis of the process characteristics of waste incineration, it can be known that among the many factors affecting the efficiency of waste incineration, furnace temperature is the most important. Higher furnace temperature is conducive to the rapid and sufficient drying of garbage in the furnace and the precipitation of volatile matter, ensuring the full pyrolysis process, and promoting the burnout of residual carbon, thereby improving the burnout degree o...
