Abstract
The utility model discloses the heat treatment carburizer emission-control equipment on a kind of flue gas leading being arranged on heat treatment carburizer, namely on exhaust emission tube pipeline, be formed with a branch road waste gas lead Gas Pipe, lead Gas Pipe mouth of pipe place at described branch road waste gas and be provided with igniter, described igniter comprises the ignition controller of the energising of resistance wire, transformer and controlling resistance silk or power-off, on the upside of the described exhaust emission tube mouth of pipe, be provided with flame detecting pin, described emission-control equipment also comprises control unit.This heat treatment carburizer emission-control equipment structure is simple, propane flammable gas is not needed to light waste gas to carry out exhaust-gas treatment as ever-burning flame, but light waste gas by resistive heater, and whether have flame by control unit according to flame detecting pin detection exhaust emission tube and then control energising or the power-off of resistance wire in igniter, while reduction production cost, ensure that equipment is safe and reliable to operation.
Description
Technical field
The utility model relates to exhaust-gas treatment field, particularly a kind of heat treatment carburizer emission-control equipment.
Background technology
Heat treatment carburizer can produce large quantity of exhaust gas in process of production, and these waste gas main components are carbon monoxide.Carbon monoxide is a kind of colourless, odorless, tasteless, nonirritant, to blood and the harmful poisonous gas of nerve, therefore can not directly be discharged in air.Waste gas burning is the waste gas that a kind of guarantee will be discharged in stove, namely carbon monoxide is produced carbon dioxide and is discharged into gas processing method in air again after burning, usual meeting arranges a little burner (being commonly called as normal bright lamp) at exhaust outlet place, by burn propane gas as burning things which may cause a fire disaster, be used for lighting waste gas, for ensureing that toxic emission out burns in time, burner must light waste gas by burn propane for a long time, and adopt this waste gas processing method, the burner propane that will consume 3 cubes per hour, the propane flammable gas of mean consumption every day 72 cubes, within 1 year, continuous seepage luminous point nozzles just need consume nearly 100,000 costs, and can not light in time when occurring that flame surprisingly extinguishes (come out of the stove or gone out by wind).
Summary of the invention
It is simple, safe and reliable that the purpose of this utility model is to provide a kind of structure, do not need propane flammable gas to light as ever-burning flame the heat treatment carburizer emission-control equipment that waste gas carries out exhaust-gas treatment.
For this reason, the technical solution of the utility model is as follows:
A kind of heat treatment carburizer emission-control equipment, be arranged on the flue gas leading of heat treatment carburizer, it is characterized in that, be included in the branch road waste gas that exhaust emission tube pipeline is formed and lead Gas Pipe, be arranged on the igniter that described branch road waste gas leads Gas Pipe mouth of pipe place, be arranged on the flame detecting pin on the upside of the described exhaust emission tube mouth of pipe and control unit, described igniter comprises resistance wire, the ignition controller of transformer and the energising of controlling resistance silk or power-off, described control unit is used for according to flame detecting pin detection exhaust emission tube with or without flame and then the energising or the power-off that control resistance wire in igniter.Preferably, described control unit is PLC control unit.
This heat treatment carburizer emission-control equipment structure is simple, propane flammable gas is not needed to light waste gas to carry out exhaust-gas treatment as ever-burning flame, but light waste gas by resistive heater, and whether have flame by control unit according to flame detecting pin detection exhaust emission tube and then control energising and the power-off of resistance wire in igniter, while reduction production cost, ensure that equipment is safe and reliable to operation.
Accompanying drawing explanation
Fig. 1 is heat treatment carburizer emission-control equipment structural representation of the present utility model.
Detailed description of the invention
Be described in detail below in conjunction with the structure of accompanying drawing to heat treatment carburizer emission-control equipment of the present utility model.
As shown in Figure 1, this heat treatment carburizer emission-control equipment is arranged on the flue gas leading 1 of heat treatment carburizer, exhaust emission tube 1 exhaust emission tube 1 pipeline is formed with a branch road waste gas and leads Gas Pipe 2, lead Gas Pipe 2 mouth of pipe place at described branch road waste gas and be provided with igniter 4, described igniter 4 comprises resistance wire, the ignition controller of transformer and the energising of controlling resistance silk or power-off, flame detecting pin 3 is provided with on the upside of described exhaust emission tube 1 mouth of pipe, described emission-control equipment also comprises control unit 5, energising and the power-off whether exhaust emission tube 1 has resistance wire in flame and then control igniter 4 is detected according to flame detecting pin 3.Described control unit is PLC control unit.
The operation principle of this heat treatment carburizer emission-control equipment is as follows:
When in-furnace temperature reaches safe temperature instillation methyl alcohol or passes into after RX gas carries out carburizing heat treatment, igniter 4 is controlled by PLC control unit, control resistance wire is energized by ignition controller, light the waste gas that branch road waste gas leads Gas Pipe 2 eliminating, and then light the waste gas of exhaust emission tube 1 discharge, after flame detecting pin detects the flame at exhaust emission tube 1 place, the ignition controller that PLC control system controls in igniter 4 makes resistance wire power-off, and when flame surprisingly extinguishes (come out of the stove or gone out by wind), when flame detecting pin does not detect flame, PLC control unit can make resistance wire energising light a fire by the ignition controller again controlled in igniter 4, ensure that waste gas is lighted in time.
Claims (2)
