Ignition device and ignition method for sinter pot test

Abstract

The invention provides an ignition device and an ignition method for a sinter pot test. The ignition device is composed of a flame uniform distribution plate, a blast blower, an air tube, a gas valve, an electromagnetic valve, a primary gas tube, a secondary gas tube, a premixing cavity, a connection seat, an electronic igniter, a protective cover, a flame detector and a computer; the computer starts the blast blower, the electronic igniter, the flame detector and the secondary electromagnetic valve in a programmable manner for pre-igniting, and judges whether the pre-igniting is successful according to a set temperature; if the pre-igniting is not successful, the computer stops the secondary electromagnetic valve, and re-ignites; if the pre-igniting is successful, the computer starts the primary electromagnetic valve for formal igniting, and the computer times; and when the ignition time reaches a set time, the computer stops the primary electromagnetic valve, the secondary electromagnetic valve and the blast blower in a programmable manner. The ignition device and the ignition method for the sinter pot test provided by the invention can economize on manpower and space, ensure uniform and stable flame temperature at the outlet of the protective cover, and realize an automatic ignition control process; and with the ignition device and the ignition method, a combustion effect of fuel can be improved, and the accuracy rate of the sinter pot test can be ensured.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to an ignition device and an ignition method for igniting a mixture fuel during a sintering cup test. Background technique [0002] During the sintering cup test, it is necessary to ignite the fuel on the surface of the mixture, and then use the negative pressure generated by the exhaust fan to gradually move down the combustion layer, and finally complete the entire sintering process. [0003] In the previous sintering cup test, because the blower was far away from the sintering cup, two valves, namely the gas valve and the combustion fan valve, needed to be opened at the same time when igniting. Two people were required to cooperate with the operation at the same time, which not only wasted manpower, but also the synchronization of the operation was poor. , it is very easy to appear hysteresis on one side, which affects the ignition effect and the uniformity of comb...

Problems solved by technology

[0003] In the previous sintering cup test, because the blower was far away from the sintering cup, two valves had to be opened at the same time when igniting, that is, the gas valve and the combustion fan valve, which required two people to cooperate at the same time, which not only wasted manpower, but also the synchronization of the operation was poor. , it is very easy to appear hysteresis on one side, which affects the ignition effect and the uniformity of combustion, and the combustion-supporting blower needs to be set up in a separate space, which causes a lot of inconvenience to the site
