Abstract

The utility model provides a low-pressure natural gas energy-saving nozzle of a water jacket furnace, which is used for an oil field ground heating water jacket furnace and is composed of a gas inlet pipe, a combustion chamber, a gas nozzle, a sucking injection chamber, a throat pipe, a mixing pipe, a mixing chamber, a combustion nozzle, a secondary combustion surface, an automatic manual air door, a main air inlet, an air inlet, a bearing and a shaft sleeve. The gas inlet pipe is welded with the combustion chamber, and the gas nozzle is connected with the combustion chamber in a threaded manner; the sucking injection chamber is welded with the throat pipe, the throat pipe is welded with the mixing pipe, and the mixing pipe is welded with the mixing chamber; the combustion nozzle is connected with the mixing chamber in a threaded manner, and the secondary combustion surface is connected with the mixing chamber in a threaded manner; a shell of the automatic manual air door is welded with the main air inlet, and a shaft of the automatic manual air door is matched with the bearing in an interference manner; the air inlet is welded with the combustion chamber, and the bearing is welded with the shaft sleeve. The low-pressure natural gas energy-saving nozzle solves the problems in the prior art that black smoke is generated, the combustion is incomplete, the environment is polluted and energy resources are wasted when the pressure of natural gas is low. Therefore, the low-pressure natural gas energy-saving nozzle can be widely used in the oil field ground heating water jacket furnace.

Description

The energy-conservation nozzle of water jacket furnace low pressure natural gas

Technical field:

The utility model relates to the energy-conservation nozzle of water jacket furnace low pressure natural gas that ground, a kind of oil field heating water jacket's stove is used.

Background technology:

At present, ground, oil field heating water jacket's stove uses at the higher water jacket furnace of gas pressure, and high-pressure natural gas is ejected in the water jacket burner hearth, and red as fire a slice, combustion efficiency are good especially, because temperature height in the stove, gas fuel burning is more thorough, and chimney is over-emitting black exhaust not.If it is just not so good than combustion efficiency on the low source of the gas to be used in gas pressure, over-emitting black exhaust, contaminated environment wastes energy.If run into the weather of blowing, the temperature in the burner hearth is lower, blows hard, and sometimes stove fire is scraped and is gone out, and influence is produced.

The utility model content:

The purpose of this utility model provides the energy-conservation nozzle of a kind of water jacket furnace low pressure natural gas, and this nozzle has solved the over-emitting black exhaust when gas pressure is low that exists in the prior art, and it is not thorough to burn, contaminated environment, the problem that wastes energy.

The technical scheme that its technical problem that solves the utility model adopts is: the energy-conservation nozzle of water jacket furnace low pressure natural gas, by air inlet pipe, the combustion chamber, gas nozzle, the chamber is penetrated in suction, trunnion, mixing tube, mixing chamber, burner noz(zle), second-time burning face, manual self closing door, the primary air import, air intlet, bearing, axle sleeve is formed: air inlet pipe and combustion chamber welding, gas nozzle and combustion chamber screwed connection, chamber and trunnion are penetrated in suction, trunnion and mixing tube, mixing tube and mixing chamber are welding, burner noz(zle) and mixing chamber, second-time burning face is screwed connection with mixing chamber, the manually shell of self closing door and primary air import welding, the axle and the bearing interference fit of manual self closing door, air intlet and combustion chamber, bearing and axle sleeve are welding; During work: low pressure natural gas enters fuel chamber by air inlet pipe, and combustion gas is sprayed by 5 gas nozzles behind the steady pressure in fuel chamber simultaneously.The air of bringing into enters mixing tube through trunnion fully to be mixed, and is all pressing mixing through mixing chamber.Through 60 ° of injections of 72 apertures on the burner noz(zle), form reciprocal combustion, form primary combustion.Having seat clay to make above the lining to burn in the inside of combustion chamber has the heat-resisting alloy raised points, very high through the heat-resisting alloy raised points temperature after the burning, does not have completing combustion gas through out-of-date generation second-time burning through this point.It is not thorough that second-time burning has solved burning, and the interior temperature of moment burner hearth is crossed low fire extinguishing problem.The air door of She Ji gaseous mixture personnel selection wage adjustment in the past is whole, locks after being transferred to the fixed position.If blow weather, the temperature in the burner hearth is too many owing to entering air, and the stove tube siphons away the temperature in the furnace chamber, has wasted the energy.Go out if blow hard also may scrape stove fire, influenced production.We utilize area pressure reduction equal pressure principle to design a cover self closing door., after certain air inflow, maintain static with manual adjustment.Air door is closed automatically when blowing, and air door is got back to the angle of former adjustment automatically when calm.

The beneficial effects of the utility model are: modern design, and relatively simple for structure, easy to use; The low pressure natural gas sufficient combustion, unburned natural gas carries out second-time burning energy-saving and environmental protection, safety; Windy day can keep temperature in the water jacket furnace, prevents that wind from blowing the fire extinguishing flame.
