Problems solved by technology
[0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. During the combustion process of the boiler, flue gas will be generated. It is discharged through the exhaust pipe installed on the top of the boiler. The flue gas contains a certain amount of solid particles and toxic gases produced by incomplete combustion, and the temperature of the flue gas is relatively high. If it is discharged directly, it will cause serious environmental pollution.

Embodiment approach
[0023] As a preferred embodiment of the present invention, the PLC control box 21 is connected to the fan 11 and the igniter 16 respectively.
[0024] As a preferred embodiment of the present invention, the lower bottom surface of the boiler shell 1 is located at the position of the ash outlet 14 and is provided with a pull-out baffle, and the rotating rod 23 of the hook 24 on the dust collector 6 is also provided with a reset spring.
[0025] As a preferred embodiment of the present invention, the exhaust gas heating pipe 20 is arranged horizontally and spirally inside the heating water tank 3 .
[0026] This PLC controls the boiler. By setting the smoke collection chamber close to it, the smoke exhaust heating pipe extends into the heating water tank and the tail gas primary discharge pipe extends to the nozzle of the cold water delivery pipe, and transfers heat to the cold water in the heating water tank for three times by burning the hot flue gas. , realize the full use o...

The invention discloses a boiler device capable of treating tail gas through PLC control. The boiler device comprises a boiler shell, an upper cover, a heating water tank, a cold water conveying pipe,a fan, support legs, an ash collecting cavity, a smoke collecting cavity, a hot water output pipe and a PLC control box; the support legs are arranged at four corners of the bottom surface of the boiler shell; the smoke collecting cavity is provided for tight bonding; a smoke discharge heating pipe extends into the heating water tank, and a tail gas primary discharge pipe extends to an orifice ofthe cold water conveying pipe; heat of hot smoke obtained by combustion is transferred to cold water in the heating water tank for three times to realize full utilization of the heat and to prevent the waste of resources; meanwhile, the tail gas exhausted by the boiler is cooled, so that the harm caused by high-temperature tail gas is prevented; a dust remover is connected to the tail gas primarydischarge pipe; through an internal structure, granular dust in the tail gas is centrifugally rotated and deposited in a dust collecting box, so that the tail gas is further treated to meet emissionstandards, and the harm to the environment by the tail gas is reduced; and the dust collecting box is simple in connecting mode and convenient to operate, and facilitates cleaning by workers.
Description
technical field [0001] The invention relates to the technical field of boilers, in particular to a PLC-controlled boiler device with tail gas treatment. Background technique [0002] The boiler is a kind of energy conversion equipment. The energy input to the boiler includes chemical energy and electric energy in the fuel. The boiler outputs steam, high-temperature water or organic heat carrier with certain heat energy. During the combustion process of the boiler, flue gas will be generated. It is discharged through the exhaust pipe installed on the top of the boiler. The flue gas contains a certain amount of solid particles and toxic gases produced by incomplete combustion, and the temperature of the flue gas is relatively high. If it is discharged directly, it will bring serious environmental pollution. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a PLC-controlled boiler device with tai...
