The invention discloses a soot-blowing control device for a boiler furnace based on heat flow online measurement, which comprises a heat flow sensor, a multiplexer, a data collector and an industrial personal computer, wherein the heat flow sensor is arranged on a film-type water wall fin at the periphery of the boiler furnace and connected to the input end of the multiplexer and used for transmitting collected heat flow to the multiplexer; the multiplexer is sequentially connected with the data collector and the industrial personal computer and used for multi-channel switching, signal amplifying and filtering; the data collector is used for converting a heat flow analog signal to a digital signal; and the industrial personal computer is used for analyzing the digital signal transmitted from the multiplexer and sending a soot-blowing signal. The invention can be used for various coal-fired power plants; and according to fouling conditions of heating surfaces in each region of the boiler furnace, realizes the sweeping in a demand quantity for the required region, improves the accuracy and the real time of fouling diagnosis for the heating surfaces of the boiler furnace, reduces the boiler failure, prolongs the lifetime of a soot-blower, saves the maintenance workload of the soot-blower, and the like.

The invention relates to the technical field of cleaning equipment, in particular to a soot blowing device with a rotary nozzle. The soot blowing device comprises a motor device, a soot blowing device and a base, a moving device is arranged at the lower end of the base, and the moving device can be adjusted up and down and can be easily moved in a labor-saving manner. A lifting device is further arranged on the base, so that the equipment can be lifted or lowered to the most appropriate height, and therefore, the equipment can be matched with various to-be-cleaned equipment. A gas tank device of the equipment is provided with a filtering tank, on one hand, the filtering effect is improved, on the other hand, a filtering pad is more convenient to replace, a gas tank as a whole does not need to be disassembled, and the working efficiency is improved. The rotary nozzle is arranged in a large horn of the equipment, pulse type impact can be formed, the cleaning capacity can be greatly improved, a cleaning agent can be added into the equipment, and therefore the cleaning capacity and efficiency are further improved. The device has the advantages of being convenient to move, adjustable in height, good in filtering effect, high in cleaning capacity and high in working efficiency.
