Abstract
The utility model relates to an adjustable ejector of an annular sleeve kiln, which comprises an injection tube, an ejection tube and an ejector outer tube. An inlet of the ejector is connected with an air outlet of an inner sleeve through an air pipeline, an outlet of the ejector is connected with an inlet of a lower nozzle of the sleeve kiln, and an inlet of the injection tube is connected with an ejection airflow pipeline. The injection tube is in threaded connection with an ejector base, and the ejection tube and the injection tube are made of carbon steel or stainless steel. Due to the fact that the injection tube is in threaded connection with the ejector base, the position of the injection tube can be adjustable. Pressure of the ejection tube and flow velocity of pumped air can be controlled by adjusting the depth of the injection tube inserted into the ejection tube. Therefore, the adjustable ejector of the annular sleeve kiln is suitable for changes of lime production working conditions, and operation flexibility can be improved.
Description
Technical field
The utility model belongs to the fluid machines technical field, relates to a kind of injector, is specifically related to the adjustable injector of a kind of annular lime kiln.
Background technology
Telescopic shaft furnace has another name called ring kiln, originates from Teller company of the graceful department of German Beckenbach Weir, and cover for seat cartridge type shaft furnace comes into operation surplus in the of existing 300 in the world.Practice shows that telescopic shaft furnace equipment is simple, and Operation and maintenance are convenient, and working environment is better, and calcination product is superior in quality, is a kind of very promising novel stove.The cooling air of cool lime is calcined inner sleeve under a section flue gas that the produces entering with also flowing in the sleeve kiln, sends into burner through the injector extraction and makes combustion air, both can make full use of heat energy, can reduce the load of combustion fan again, the reduction power consumption.Injector is to utilize fluid to transmit energy and quality equipment, and adopting has the certain pressure fluid to spray through the nozzle that symmetry is uniformly distributed with into certain skew back degree, is aggregated on the focus.Because injector speed is high, can change pressure into the speed ability, air-breathing district pressure is reduced produce vacuum, will be taken away by draw fluid.The pressure of the determining positions injector of injection playpipe in the injector, influence is by the flow velocity of intake-gas.When sleeve firer condition condition changes, need to regulate the flow velocity of suction sleeve kiln inner sleeve cooling air, the playpipe of the injection blower fan that prior art is used is connected as flange with the injector base, and fixed-site can not be regulated, and makes troubles to production.
Granted publication number is the open " injector that a kind of adjustable spraying apparatus is carried especially for the strength of staple fibre of CN201560262U.Mouth-piece, air inlet and discharging opening are formed the injector body of a skew T form; On the top panel of air inlet, strip hole is arranged; Sealing is inserted with plate in the strip hole; Form aditus laryngis between the front end of plate and the lower panel of air inlet, the position of adjustment plate can change the size and the spray angle of aditus laryngis.It is simple in structure, and is easy to maintenance, and cost is low, the adjustable size of aditus laryngis.”。This patented technology is not suitable for the inner sleeve cooling air of sleeve kiln suction high temperature.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, the utility model provides a kind of annular lime kiln adjustable injector, makes the playpipe adjustable positions of injector, changes to adapt to the lime production status, improves operating flexibility.
The adjustable injector of the utility model annular lime kiln comprises playpipe, induction tunnel, injector outer tube.The inlet of injector is connected with the inner sleeve gas vent through gas piping, export with the sleeve kiln under burner enter the mouth and be connected, the inlet of playpipe is connected with the injection airflow pipeline.Playpipe is connected with the injector whorl of base, and the position of the relative injector of playpipe can up-down adjustment.
The material of induction tunnel and playpipe is carbon steel or stainless steel.
The playpipe of the utility model injector adopts with the injector whorl of base and is threaded, and has realized the adjustable of playpipe position.Through regulating the degree of depth of playpipe insertion induction tunnel, can regulate the pressure of induction tunnel and, adapt to the variation of lime production status condition by the flow velocity of intake-gas, improve the operating flexibility of sleeve kiln.
Description of drawings
Fig. 1 is the structural representation of the adjustable injector of the utility model annular lime kiln;
Fig. 2 is the screw connection point structure chart.
Wherein
Burner, 10-adapter sleeve under 1-injector base, 2-gas piping, 3-inner sleeve gas vent, 4-injection airflow pipeline, 5-screw connection point, 6-playpipe, 7-induction tunnel, 8-injector outer tube, the 9-sleeve kiln.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The adjustable injector of the utility model kind annular lime kiln is as shown in Figure 1, comprises playpipe 6, induction tunnel 7, injector outer tube 8.The inlet of injector is connected with inner sleeve gas vent 3 through gas piping 2, export with the sleeve kiln under burner 9 enter the mouth and be connected, the inlet of playpipe is connected with injection airflow pipeline 4.Injector is an adjustable structure, and induction tunnel is threaded with injector base 1.As shown in Figure 2, adapter sleeve 10 is housed on the injector base, adapter sleeve is an internal thread, playpipe is an external screw thread, adapter sleeve and playpipe threaded engagement.The material of induction tunnel and injection air-flow playpipe is a stainless steel.
Under the effect of playpipe jet-stream wind, 600～800 ℃ of gas is made circulating air through inner sleeve gas vent 3, gas piping 2 and induction tunnel 7 burner 9 under the sleeve kiln in the sleeve kiln inner sleeve.When working condition or when producing load and changing, through the playpipe 6 of rotation injector, regulate the degree of depth that injector inserts induction tunnel 7, realize to pressure with by the adjusting of intake-gas flow velocity.
Claims (2)
1. adjustable injector of annular lime kiln; Comprise playpipe (6), induction tunnel (7), injector outer tube (8); The inlet of injector is connected with inner sleeve gas vent (3) through gas piping (2), export with the sleeve kiln under burner (9) enter the mouth and be connected, the inlet of playpipe is connected with injection airflow pipeline (4); It is characterized in that: said playpipe is threaded with injector base (1), and the position of the relative injector of playpipe can up-down adjustment.
2. annular lime kiln injector according to claim 1 is characterized in that: the material of said induction tunnel and playpipe is carbon steel or stainless steel.
