Ammonium salt anti-blocking filtering device of waste gas combustion treatment equipment

Abstract

The invention discloses an ammonium salt anti-blocking filtering device of the waste gas combustion treatment equipment. The ammonium salt anti-blocking filtering device of the waste gas combustion treatment equipment comprises an outer shell body, wherein a first detection head of a a differential pressure gauge is arranged on an inlet pipe in a communicating mode, and a second detection head of the differential pressure gauge is arranged on an outlet pipe in a communicating mode; an elastic connecting plate is arranged on the top wall of an inner cavity of the outer shell body in a connecting mode, and a plurality of ceramic rings are fixedly arranged in the frame plate; a baffle is fixedly arranged at an output end of an air cylinder, an adjusting block is fixedly arranged on the baffle, and a spraying head inclining downwards is arranged on a corrugated communicating pipe in a communicating mode; and a first connector pipe is arranged on a mixing box in a communicating mode, a second connector pipe and a third connector pipe are arranged on the first connector pipe in a communicating mode, and the third connector pipe communicates with a return pipe. The ammonium salt anti-blocking filtering device of the waste gas combustion treatment equipment can automatically carry out back washing when the ceramic rings are blocked by ammonium salt, and is comprehensive in washing, free of dead angles, low in washing water consumption, capable of effectively saving resources, simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of anti-blocking devices, in particular to an ammonium salt anti-blocking filter device for waste gas combustion treatment equipment. Background technique [0002] Regenerative ceramics are installed in the hearth of the existing regenerative waste gas incinerator, and the waste gas enters the furnace through the heat storage ceramics for incineration. The waste gas contains some particulate matter, which is easy to block the ceramics, and the resistance increases. The frequency of the waste gas fan increases, so that the waste gas can pass through the ceramics. To a certain extent, when the exhaust gas cannot pass through, the ceramics must be replaced. To replace the ceramics, the incinerator needs to be cooled, the old ceramics are removed, new ceramics are installed, and the oven is heated up. The construction period takes 4-5 days, which affects production and costs high. [0003] The defects in the pri...

[0002] Regenerative ceramics are installed in the hearth of the existing regenerative waste gas incinerator, and the waste gas enters the furnace through the heat storage ceramics for incineration. The waste gas contains some particulate matter, which is easy to block the ceramics, and the resistance increases. The frequency of the waste gas fan increases, so that the waste gas can pass through the ceramics. To a certain extent, when the exhaust gas cannot pass through, the ceramics must be replaced. To replace the ceramics, the incinerator needs to be cooled, the old ceramics are removed, new ceramics are installed, and the oven is heated up. The construction period takes 4-5 days, which affects production and costs high

[0003] The defects in the prior art include but are not limited to: 1. The existing device does not have an online flushing function. When the ceramic ring is blocked by ammonium salt, it needs to be manually disassembled for cleaning, which is time-consuming and laborious and affects the use; 2. The existing device When cleaning, it is necessary to use the water flow with cleaning agent to perform multiple flushes, and then use clean water flow for final flushing. However, the existing device also needs an additional ratio structure of concentrated cleaning agent and water flow. The device is complicated and cannot Repeated use of the cleaning solution wastes resources and is not convenient for large-scale promotion and use
