Abstract

The utility model discloses an integration igniter which comprises two venturi ejector-mixers 7, a flame crossover tube 14, a gas pipe 9, a flameless burner 15, a burning nozzle 11, a windshield 16, a high-pressure electric arc ignition electrode 13 and an embedded-type armoured thermocouple 10. One mixer achieves complete premixing to cause an air mixing amount to be bigger than an air mixing amount needed by theory burning, and the mixed air is taken as an ignition airflow; and the other mixer takes primary air as burning flame of a pilot burner. The flameless burner 15 has favorable flame rigidity to ensure the wind and rain resistance capacity, and partial premixing and the burner ensure the length and the brightness of flame and also ensure the wind and rain resistance capacity under the support of the flameless burner 15. The electric arc ignition electrode 13 is installed at the lower part of an igniter far away from torch flame, and a temperature thermocouple is installed in the gas pipe having long service life and low energy consumption; the temperature thermocouple has the advantages of simple installation and low matching cost.

Description

Integrated igniter

Technical field

The utility model belongs to igniting and field of combustion technology, is specifically related to a kind of integrated igniter of long-life that is used for oil, chemical industry, electric power, smelter imflammable gas Venting and Flare Stack System.

Background technology

The imflammable gas Venting and Flare Stack System is very important safety, the environmental protection facility of oil, chemical industry, electric power, smelter process units indispensability, and torch lighter is the most important equipment that guarantees the torch normal ignition.Present torch ignition equipment is made up of with normal bright lamp and temperature thermocouple the high-altitude ignition device of split.Normal bright lamp adopts the part primary air and mixes, and has wind resistance rain ability, and Fuel Consumption is big; Temperature thermocouple is installed in the altar lamp next door, is subjected to the baking life-span of torch flame short; The high-altitude ignition device is that open flue passes combustion, and carbon distribution is serious, and wind loading rating is poor, can lose efficacy when the ignitor carbon distribution is serious, and the life-span difficult in maintenance is short.These equipment are installed in tens meters to more than 100 meters high-altitude, in case go wrong, can't in time safeguard, repair, and have a strong impact on the safe operation of flare system; Normal in addition bright lamp, igniter, the independent respectively installation of thermocouple, combination property is poor, and installation is complicated, the expense height.

Summary of the invention

The purpose of this utility model is exactly high, for a long time do not need to safeguard, the life-span low-cost torch lighters long, energy-conserving and environment-protective of a kind of reliability of invention.

For achieving the above object, the technical solution adopted in the utility model is: adopt the double-venturi mixer-ejector, one reach fully premixed and, make air mix two greater than theory burning required air quantity, as the igniting air-flow; Another blender part primary air is as the combustion flame of altar lamp.The design double burner is worked simultaneously, and flameless burner flame good rigidity guarantees wind resistance rain ability, and partly-premixed and burner guarantees the length of flame and brightness, in the rainy same wind resistance ability that guarantees of the support of flameless burner.Ignitor is installed in the igniter bottom away from torch flame, temperature thermocouple is installed in Gas Pipe inside, the high-temperature baking that makes electric instrument parts avoid torch flame like this prolongs its life-span greatly, adopts integrated design to reduce the expense and the operating expenses of system's pipe arrangement, automatic instrument(s).

Advantage of the present utility model is:

1, the life-span is grown, does not need for a long time to safeguard

2, property height, energy consumption are low

3, the temperature thermocouple life-span is long

4, simple installation, support expense are low
