Abstract
A high-temperature mixing flammable gas explosion detection device is provided with a no-spark heating belt on the external wall of a sealing cylinder which can bear a certain explosion pressure and can contain the flammable mixing gas; a flange at one end of the sealing cylinder is provided with a single-direction gas inlet, a pressure discharge hole and a monitoring sensor; the cylinder is internally provided with a movable piston; a movable piston handle is extended out of the cylinder by the other end flange of the sealing cylinder; an ignition electrode is fixed to the movable piston; the sealing cylinder wall is provided with a temperature controlling sensor. The utility model provides the detection device for the explosion of high-temperature flammable mixing gas in the furnace (kiln), and brings guarantees to the safe production.
Description
(1) technical field:
The utility model belongs to a kind of pick-up unit.
(2) background technology:
To add hot exhaust gas and send back to the kiln internal combustion in order to save energy people in the graphite electrode roasting process, combustible component is very complicated in this moment stove, the happen occasionally danger of flammable gas explosion of igniting again in kiln.The method of often using inflammable gas or oxygen concentration to survey for the present people of the generation that prevents explosion accident realizes safety practices such as warning, shutdown.But the prerequisite that is to use above method is to understand the explosion limits of inflammable gas or the oxygen concentration limit of burning.Because the gas componant complexity in the burning kiln (stove) is various, can't learn the blast parameter of this mixed gas at all, therefore can't adopt the method for detectable concentration to realize safety in production.
(3) summary of the invention:
For solving the explosibility detection of high temperature mixed combustible gas body, the utility model provides a kind of high temperature mixed combustible gas body blast pick-up unit that can be used for the safety anti-explosive of electrode production and gas fired-boiler.
The utility model is a two ends flange seal on a metal cylinder, and wherein end weldering is dead, and other end bolted is used for the splendid attire inflammable gas also can bear certain explosive force, at the outer wall of cylindrical shell the no-spark heating tape is housed, and is used for heating cylindrical shell.On the flange of sealing bore one end, have unidirectional gas access and relief hole, retaining valve is equipped with at the place in unidirectional gas access, and rupture disk is equipped with at the place at relief hole, and the blast monitoring sensor also is housed on the flange of this end, be used for to propagate after the inflammable gas igniting in the monitoring device i.e. blast.Moving plug is housed in tube, and spark electrode is fixed on the moving plug, and the other end of sealing bore is opened a through hole, and the moving plug handle stretches to outside the tube by this hole, and the moving plug handle can be swung, and is also rotatable.Spark electrode is used for the burning mixture in the firing device, spark electrode passes through moving plug, insulating with insulating material by locating, to avoid short circuit, moving plug is used to form the vacuum in the test cylindrical shell, and guarantee certain tightness, and temperature-control senser is housed on barrel, be used for the temperature control of barrel.Use the utility model, at first utilize the 6 pairs of metal cylinders 7 in no-spark heating tape to heat, utilize temperature-control senser 8 to regulate heating-up temperature to the device interior temperature; Spur piston handle 5 then, from unidirectional gas collecting mouth 1 suction burning mixture, the starting ignition electrode 3 then, utilize monitoring sensor 2 to survey the flame propagation situation of inner barrel.Repeatedly utilize between the test to rush down and press hole 9 waste gas of releasing.
The utility model provides a kind of stove (kiln) pick-up unit that can interior high temperature burning mixture explode, thereby has brought assurance for keeping the safety in production.
