The invention relates to a spraying pipe provided with a pressure detection device and capable of realizing remote transmission and monitoring. The spraying pipe has the main characteristic that a pressure guide pipe and a flushing water pipe are additionally arranged at an inlet section of the spraying pipe, and a pressure sensor and a remote signal transmission module are mounted; operation pressure of desulfuration slurry in the spraying pipe is converted into a current signal, and then the current signal is further transmitted to a PC or a mobile phone terminal through the remote transmission module to monitor the pressure of the slurry in the spraying pipe in real time; therefore, safe and stable operation of a desulfuration system is guaranteed. The spraying pipe mainly comprises thepressure guide pipe, the flushing water pipe, the pressure sensor, the remote pressure transmission module and the like. The pressure of the spraying pipeline is monitored in real time through the above devices, so that an abnormality of the spraying pipe can be found out in time and then eliminated; the service life of the spraying pipe is prolonged, and long-term stable and effective operationof the desulfuration system is also guaranteed.
