Description

Technical Field

[0001] The invention relates to the technical field of industrial waste gas treatment, in particular to a combustion exhaust gas torch steady lamp system. Background Art

[0002] Torch combustion covers numerous fields, including oil refining, petrochemicals, organic chemicals, inorganic chemicals, polymer chemicals, biochemicals, coal chemicals, natural gas, and oilfield extraction. It is a crucial environmental protection device used to combust waste gases, tail gases, and harmful gases emitted by combustion devices. The pilot light, the primary structure of the flare head, provides a stable heat source for the torch to burn various types of waste gases with varying calorific values, ensuring the flare flame does not go out.

[0003] The torch lights in the prior art are all designed to improve the success rate of ignition or the ignition effect. For example, patents CN215001632U and CN206247355U have made improved designs in terms of ignition structure or fuel mixing. Patent CN103836623B achieves the effect of low fuel gas consumption by strengthening the mixing with air. However, the above technical solutions all consume conventional fuel gas (generally a gas with stable calorific value and easy to ignite, such as natural gas). Usually, the torch directly consumes fuel gas, which is basically 1 to 4 m 3 / h, and it is continuous all year round, so the annual gas consumption is very large, which is not only not conducive to energy conservation and environmental protection, but also increases the production cost of the enterprise.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0016] See also Figure 1-3The present invention provides a technical solution: a combustion exhaust gas torch long-burning light system, including a main fuel pipe 1, a filter a2, a filter b3 and an ignition assembly 7, the filter a2 and the filter b3 are connected in parallel and serve as a backup for each other to supply gas to the main fuel pipe 1 and filter out impurities in the exhaust gas, the upper end of the main fuel pipe 1 is fixedly installed with a sleeve 5, the upper end of the sleeve 5 is fixedly connected with a cone-shaped wind shield 6, a thermocouple 11 is installed in the wind shield 6, the thermocouple 11 is used to measure the temperature of the combustion head, and then monitor the combustion situation.

[0017] The upper end of the main fuel pipe 1 is inserted into the bottom of the inner cavity of the sleeve 5 and an annular gap is formed to allow the combustion air to enter. The inner cavity of the sleeve 5 is provided with a heat-insulating ceramic sleeve, and the inner cavity of the ceramic sleeve forms a heat storage chamber. The upper end of the main fuel pipe 1 is provided with a high-speed nozzle 13. When the high-speed nozzle 13 sprays exhaust gas, according to the Bernoulli principle, air will be sucked in from the outside through the gap. A vertical heating wire 10 is fixedly installed in the middle of the high-speed nozzle 13. The heating wire 10 is located in the heat storage chamber to reduce heat loss. The heating wire 10 is connected to the battery 4 through a cable. The battery 4 is charged during off-peak hours. The heating wire 10 is continuously heated to ignite the exhaust gas. The upper end of the sleeve 5 is fixedly connected to a flame stabilizing plate 12. There are several circular holes evenly distributed on the flame stabilizing plate 12. The flame stabilizing plate 12 is used to evenly disperse the flame. The inner cavity of the main fuel pipe 1 is provided with a coaxial sleeve 14, and the cable passes through the sleeve 14. The sleeve 14 is made of heat-insulating material. The side of the wind shield 6 is connected to the flame transmission tube 9, and the ignition assembly 7 is installed on the side of the flame transmission tube 9. The lower end of the flame transmission tube 9 is fixedly installed with an ignition assembly 8.

[0018] Pilot assembly 8 includes a nozzle 81, with a distribution pipe 83 welded to its lower end. Distribution pipe 83 is circumferentially provided with a plurality of air inlet holes 85. An adjustment ring 82 is screwed onto the outer side of distribution pipe 83. By rotating adjustment ring 82 to move it up and down, the coverage of air inlet holes 85 can be adjusted. The fewer air inlet holes 85 covered, the more air can enter. Fuel inlet pipe 84 is mounted at the lower end of distribution pipe 83. The inner diameter of fuel inlet pipe 84 decreases from bottom to top, and an injection head 86 is mounted at the upper end. Injector head 86 is located in the middle of the lower end of nozzle 81. If the heating wire 10 is insufficient to ignite the exhaust gas, pilot gas is introduced through pilot assembly 8, ignited, and then ignited.

[0019] Working Principle: Exhaust gas enters the main fuel pipe 1 through filter a2 or filter b3. Battery 4 provides electricity to heat the heating wire 10. Exhaust gas is ejected from high-speed nozzle 13 into sleeve 5, and combustion-supporting air is drawn in through the gap between sleeve 5 and main fuel pipe 1. The mixture of exhaust gas and air ignites when it passes through heating wire 10 and is ejected from windscreen 6. An auxiliary ignition assembly 8 is also provided. If heating wire 10 fails to ignite, gas and air enter through ignition assembly 8, igniting a flame that is then drawn to windscreen 6 to ignite the exhaust gas.
