Flue fire extinguishing purifier for roasting furnace

Abstract

The invention discloses a flue fire extinguishing purifier for a roasting furnace. The flue fire extinguishing purifier is characterized by comprising an outer pipe, a coil pipe, a water inlet pipe, nozzles, an electromagnetic valve, a thermoelectric couple and a control instrument, wherein the outer pipe is a pipeline of which the both ends are opened; the coil pipe is welded on an inner wall of the outer pipe and is communicated with the water inlet pipe; a plurality of nozzles are arranged on the coil pipe; the water inlet pipe penetrates through the outer pipe and is connected with a water pipe through the electromagnetic valve; the thermoelectric couple is fixed in the outer pipe and is connected with the control instrument; the control instrument is connected with the electromagnetic valve; and the outer pipe, the coil pipe, the water inlet pipe and the nozzles are all made of stainless steel materials. According to the flue fire extinguishing purifier for the roasting furnace disclosed by the invention, a temperature of a flue is monitored by the thermoelectric couple, and the electromagnetic valve is controlled to spray water so as to extinguish fire; the flue fire extinguishing purifier is not only simple in structure, low in construction cost, and production cost can be effectively saved, but also the flue fire extinguishing purifier is convenient to use, safe and reliable. Therefore, the flue fire extinguishing purifier is particularly suitable for enterprises in which carbon calcination is implemented.

Description

technical field [0001] The invention relates to the technical field of carbon roasting flue gas purification, in particular to a fire extinguishing purifier for a roasting furnace flue. Background technique [0002] In today's society, environmental protection requirements are getting higher and higher, and there are strict requirements for carbon roasting flue gas emissions. At present, carbon roasting flue gas treatment generally adopts electric coke capture dust collector, and roasting flue gas needs to meet the national emission standards after being treated by electric coke capture: [0003] 1. Sulfur dioxide net 400mg / m3 [0004] 2. Tar emission concentration 12mg / m3 [0005] 3. Dust emission concentration reaches: 30mg / m3 [0006] 4. Benzopyrene: 0.0025 mg / m3 [0007] 5. Ringelmann blackness <1 [0008] 6. Fluoride <72 mg / m3 [0009] At present, the flue gas from the roasting furnace first enters the conditioning tower through the flue for pretreatment, an...
