Problems solved by technology

[0002] There are generally two ways to monitor the flame state of the lime rotary kiln during the gas oven: the first is to observe the flame state directly at the observation port manually, and the second is to install a surveillance camera at the observation port to introduce the picture into the central control room, but it is still manually monitored. Keep an eye on the flames
The common disadvantage of the two methods is that people monitor the flame state, which is not continuous, and the flame extinguishment cannot be found in time. A large amount of gas leaks and accumulates in the rotary kiln, which may lead to explosion accidents.
In addition, once an explosion accident occurs, the use of the first method may cause casualties

Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] In the present invention, in the case of no opposite explanation, the orientation words included in the term "upper, lower, down, top, and side" only represent the orientation of the term in the conventional use state, or understand the technical staff of the field in the field. colloquial term and should not be construed as a limitation of the term.

[0024] Such as figure 1 It shows that the invention provides a white -gray swing kiln flame monitoring device, including infrared flame sensor 1. Control circuit 2. Control module 3, PLC4, monitoring display 5, flameout protection alarm 6. Among them, control circuit 2 can be infrared flame sensors from in...

Abstract

The invention discloses a flame monitoring device of a lime rotary kiln. The device comprises an infrared flame sensor, a control circuit, a control module, a PLC, a monitoring display, a flameout protection alarm, wherein the control circuit is capable of transmitting electrical signals converted by the infrared flame sensor to the control module. The control module is capable of converting the electrical signals into digital signals and transmitting the digital signals to the PLC. After receiving the digital signals, the PLC can control the displaying of flame state on the monitoring displayaccording to a pre-set value, and starts the flameout protection alarm upon an alarm limit value is reached. According to the flame monitoring device of the lime rotary kiln, manual detecting of flame state in the prior art is replaced by equipment detection, namely the flameout protection alarm can immediately respond as long as flame is out, so that emergency treatment measures can be taken immediately, in this way, equipment detection is more accurate compared with manual detection; and in addition, manual approaching to the lime rotary kiln for detection is avoided, which is more safer.

Description

technical field [0001] The invention relates to flame monitoring of a lime rotary kiln, in particular to a flame monitoring device for a lime rotary kiln. Background technique [0002] There are generally two ways to monitor the flames when the white -gray swing kiln monitors the flame when the gas is drying. Keep an eye on the flames. The disadvantage of the commonality of the two methods is that people monitor the state of flames. They are not continuous. They cannot discover the extinguish of flames in time. A large amount of gas leakage of gas is gathered in the rotary kiln, which may lead to the occurrence of burning accidents. In addition, in the event of an explosion accident, the adoption of the first method may cause casualties. [0003] Therefore, how to solve the disadvantages of manual fire inspection to provide a technical solution for non-manual monitoring of the flame state is a technical problem to be solved urgently at present. Contents of the invention ...
