Abstract
The utility model discloses a direct and continuous thermometric device in gas generator, comprising a thermocouple, a protecting tube and an electron potential difference gauge. The protecting tube is composed of inner and outer protecting tubes, a soft protecting tube and a leading out protecting tube. The inner and outer protecting tubes vertically pass through the rotation center of a fire grate from a furnace bottom and extend to a furnace chamber. The outer protecting tube is fixed on the fire grate, and the leading out protecting tube is fixed on an ash collecting box body of the furnace bottom. The utility model is provided with a supporting assembly of the protecting tube to guarantee that the inner protecting tube is not rotated following the fire grate. The utility model has the advantages of high temperature resistance, corrosion resistance, simple structure and convenient installation and is capable of bearing the knock and abrasion in the furnace and being used for long term.
Description
The utility model is a kind ofly can directly carry out thermometric device continuously to the inner gasification layer of coal (Jiao) Gas-making Furnace.
At present, numerous middle-size and small-size nitrogen fertilizer plant produces synthetic ammonia with coal generating gas, and Gas-making Furnace adopts the method for fixed bed gasification of solid fuels, and temperature is along with the process of chemical reaction constantly changes in the stove, at any time grasping the temperature of gasification layer in the stove, is the key of carrying out optimum operation control.But because temperature higher (can reach about 1300 ℃) in the stove, fire grate is gyrating, and therefore the device that can directly measure gasification layer temperature is not continuously arranged so far.Record the low temperature of ratio gasification layer temperature of hysteresis continuously in the practice or from gas outlet and furnace bottom, or temperature measuring equipment is inserted the furnace wall discontinuously, record the temperature of a period of time.A kind of method in back will be inserted a plurality of long temperature measuring equipments on a plurality of cross sections of furnace wall, the sealing problem between itself and the furnace wall also is difficult for solution.In a word, present technology can not get gasification layer continuous temperature curve in the stove, still operates control by rule of thumb to a great extent, makes coal consumption amount big, and gas making efficient is not high.
The purpose of this utility model is the device that design places energy continuous coverage gasification layer temperature in the coal generating gas stove.
The utility model technical solution is as follows:
Temperature measuring equipment by thermopair, interior protection tube, outer protection tube, soft protection tube, draw that protection tube, protection tube support assembly and secondary instrument---electron potentiometer is formed.The inside and outside protection tube that thermopair is housed vertically passes the fire grate center of rotation by furnace bottom and stretches to burner hearth, and interior protection tube lower end connects soft protection tube successively, draws protection tube and electron potentiometer.Outer protection tube is fixed on the fire grate, rotates with fire grate, draws protection tube and is fixed on the furnace bottom dust collecting box body.The protection tube support assembly comprise cover at the bottom of the interlayer that outer protection tube lower end connects and be vertically fixed on the protection tube outer wall and insert the plate, plate of cover at the bottom of the interlayer can be with fire grate play, move left and right up and down; thereby interior protection tube also can be in this scope play, move left and right up and down, but interior protection tube does not rotate with fire grate.
Specific embodiments of the present utility model is described further with reference to the accompanying drawings.
Fig. 1 is the utility model installation site synoptic diagram in Gas-making Furnace.
Fig. 2 is the utility model total structure (part provides section) synoptic diagram.
As shown in Figure 1, the utility model temperature measuring equipment (2) is installed in the Gas-making Furnace (1), is upward through fire grate (3) rotation center by furnace bottom dust collecting box (4) and stretches to burner hearth.
As shown in Figure 2, thermopair (6) is contained in the interior protection tube (7), and interior protection tube lower end connects soft protection tube (13) successively and draws protection tube (17), and thermocouple wire inserts electron potentiometer through drawing protection tube.Outer protection tube is divided into upper/lower terminal; epimere (5) is pipe cermet material, the top closure; protection tube stretches into the burner hearth part in covering; bottom cylinder iron pressure cap (8) is integrally welded with fire grate (3); gap between pressure cap and the outer protection tube epimere is filled with cementing agent (18), plays buffer action when expanding with heat and contract with cold.Hypomere (19) has the sleeve pipe of two parallel ring flanges (10,11) for the bottom, use fastening nut (15) to be fixed on the fire grate, and two ring flanges usefulness screw rods are fixedly connected.Plate (12) in being vertically fixed on the protection tube outer wall inserts between the ring flange interlayer; itself and lower floor ring flange contact position are lined with slip annulus (14); the upper and lower two sections contact positions of outer protection tube also are lined with spring bearing (9); purpose is the frictional resistance of internal protection tube when reducing outer protection tube rotation, keeps interior protection tube not rotate.The L-shaped sigmoid of soft protection tube (13), protection tube it and interior protection tube, is drawn and is wanted strict seal between the protection tube at certain limit play up and down in adapting to.Drawing protection tube (17) is drawn thermocouple wire by the dust collecting box wall.
For fear of the suffered mechanical shear stress of interior protection tube, between inside and outside protection tube, be provided with one section and strengthen protection tube (16), its lower end is fixed on the plate.
Among the embodiment, thermopair can be selected platinum Pt Rh or elements such as tungsten Lei-tungsten Lei or nickel chromium triangle-chrome-silicon, and the multiple heat galvanic couple can be set in interior protection tube, measures the gasification layer temperature of variation continuously.Interior protection tube can adopt refractory metal material to make as 2520 stainless-steel tubes or nickel 25 titaniums etc., and soft protection tube is made with soft metal or heat-resisting soft pipe, protects hypomere outward and draws protection tube and make with the common metal material.
The utility model effect is as follows:
1, high temperature resistant, corrosion-resistant, can bear stove inner impact, wearing and tearing, the assurance signal is correctly drawn, and can carry out continuously for a long time temperature survey.
2, only use a covering device thermometric, simple in structure, installation and maintenance are convenient.
3, directly measure gasification layer temperature, dynamic characteristic is good, can obtain gas cycle period temperature variation curve processed, provides advantage for further operating automatic control with microcomputer.
