Problems solved by technology
The coulometric sulfur measurement method needs to use a pump as the power source. Since the sulfur concentration in the gas changes with time, it is difficult to accurately measure the sulfur content. At the same time, the life of the pump is also shortened due to the unbalanced load.

The invention discloses a neutralization-process sulfur detector with an oxygen flow rate control function, belonging to the field of automatic measuring equipment for sulfur content in coal. The sulfur detector comprises a combustion furnace fixed on a bottom plate, a combustion pipe arranged in the middle of the combustion furnace, a sucking pump, a gas collecting bottle filled with hydrogen peroxide solution, an oxygen bottle filled with oxygen, a gas guide pipe and an oxygen flow rate control device, wherein the gas collecting bottle and the oxygen bottle are respectively connected with the two ends of the combustion pipe through the gas guiding pipe, sealing heads are arranged at the two ends of the combustion pipe, and the sucking pump extends above the liquid level of the gas collecting bottle through the gas guiding pipe; the oxygen flow rate control device is arranged between the oxygen bottle and the combustion pipe and comprises a throttle main body, a first damping piece, a second damping piece, a first static pressure sensor, a first dynamic pressure sensor, a rotating shaft, a second static pressure sensor and a second dynamic pressure sensor. The neutralization-process sulfur detector with the oxygen flow rate control function has a simple and reasonable result and can be used for stably controlling the oxygen flow rate.
Description
technical field [0001] The invention mainly relates to the field of automatic measurement equipment for sulfur content in coal, in particular to a neutralization method sulfur measuring instrument with the function of oxygen flow rate control. Background technique [0002] Sulfur content is one of the important indicators for evaluating coal quality. In order to accurately and quickly measure the sulfur content in combustible substances, a sulfur meter is generally used as a common measuring device. In the prior art measuring equipment, the coulometric sulfur measuring method is adopted. The coulometric sulfur measurement method needs to use a pump as a power source. Since the sulfur concentration in the gas changes with time, it is difficult to accurately measure the sulfur content. At the same time, the life of the pump is also shortened due to the unbalanced load. [0003] As one of the rapid determination methods of total sulfur in coal, the high-temperature combustion...
