A kind of vapourizing furnace preheating mouth shutoff brick comprises right cylinder, it is characterized in that: a cylindrical end is a cone, and right cylinder and cone are one; The face that right cylinder and cone join is provided with the right cylinder trim, and the side of cone is provided with bevelled sealing surface.
According to described vapourizing furnace preheating mouth shutoff brick, it is characterized in that: the material of said bevelled sealing surface adopts refractory fibre containing zirconium; The material of right cylinder trim adopts aluminosilicate refractory fiber.
According to described vapourizing furnace preheating mouth shutoff brick, it is characterized in that: said right cylinder and cone adopt high chromium fireproof material.
According to described vapourizing furnace preheating mouth shutoff brick, it is characterized in that: the tapering of said cone is 5 °-7 °.
The utility model has the advantages of and be: can improve the sealing effectiveness of shutoff brick, prevent vault position gas blowby overtemperature; Can prevent the sintering of shutoff brick and burner chamber brick effectively, be convenient to change the shutoff brick, prevent to damage burner chamber brick in the replacing process, prolong the work-ing life of vapourizing furnace refractory brick, reduce production costs; The firebrick structure that is used for the shutoff of multi-nozzle vapourizing furnace vault, this structure easy accessibility, obturation effect are good, prevent the sintering adhesion, are convenient to dismounting.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the accompanying drawing: 1, right cylinder; 2, right cylinder trim; 3, cone; 4, bevelled sealing surface.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:
The utility model is as shown in Figure 1, and a kind of vapourizing furnace preheating mouth shutoff brick comprises right cylinder 1, and it is characterized in that: an end of right cylinder 1 is a cone 3, and right cylinder 1 and cone 3 are one; Right cylinder 1 is provided with right cylinder trim 2 with the face that cone 3 joins, and the side of cone 3 is provided with bevelled sealing surface 4.According to described vapourizing furnace preheating mouth shutoff brick, it is characterized in that: the material of said bevelled sealing surface 4 adopts refractory fibre containing zirconium; The material of right cylinder trim 2 adopts aluminosilicate refractory fiber.According to described vapourizing furnace preheating mouth shutoff brick, it is characterized in that: said right cylinder 1 adopts high chromium fireproof material with cone 3.According to described vapourizing furnace preheating mouth shutoff brick, it is characterized in that: the tapering of said cone 3 is 5 °-7 °.
The embodiment of the utility model is following:
Yankuang Group Ltd. and East China University of Science successfully develop the novel multi-nozzle opposed type coal water slurry gasification technology with independent intellectual property right; Broken of the monopolization of external transregional company, for China's energy and Coal Chemical Industry market provide the new technology with independent intellectual property right to coal water slurry gasification technology.This device is safe and reliable to operation, and level of automation is high, controls flexibly, and the ordinary production of the driving transitional period is short, and performance and technical indicator are reached the international leading level.With external coal water slurry gasification compared with techniques, have the gasification efficiency height, technical indicator is advanced.Vapourizing furnace load adjustable extent is big, can be with the company of pressure to throw, and advantages such as maximization operate steadily, suit.
This shutoff brick structure is combined by a right cylinder 1 and a cone 3, cooperates installation with vault burner chamber refractory brick.The tapering of the bevelled sealing surface 4 of shutoff brick is 6 °, cooperates with the internal surface of burner chamber brick, forms the back taper gap between shutoff brick and the burner chamber brick.The bevelled sealing surface 4 spraying refractory fibre containing zirconium table linings of shutoff brick, the coating structure layer belongs to flexible materials, and thickness is 3mm, can improve sealing property.Sprayed coating can prevent sintering under shutoff brick and the burner chamber brick high temperature, and when changing refractory brick, sprayed coating is stressed to come off, and is convenient to pull down the shutoff brick.Clearance seal on the right cylinder trim 2 of shutoff brick and the fire door brick between the plane adopts the aluminosilicate refractory fiber pad; The top common airtight refractory ceramic fibre cotton that is connected with of the top and fire door brick of shutoff brick.The matrix of shutoff brick is high chromium refractory materials, after the HS grinding tool compression moulding through special use, puts into reducing atmosphere and adds heating kiln, through high temperature sintering.Sprayed coating does not need heating curing before using; After high temperature sintering is accomplished, use fiber spray gun to carry out the surface spraying, filamentary material and tackiness agent mixing are sprayed directly on the working-surface; Form three-dimensional network shape article construction, spraying can be come into operation after accomplishing.
The utility model can improve the sealing effectiveness of shutoff brick, prevents vault position gas blowby overtemperature; Can prevent the sintering of shutoff brick and burner chamber brick effectively, be convenient to change the shutoff brick, prevent to damage burner chamber brick in the replacing process, prolong the work-ing life of vapourizing furnace refractory brick, reduce production costs; The firebrick structure that is used for the shutoff of multi-nozzle vapourizing furnace vault, this structure easy accessibility, obturation effect are good, prevent the sintering adhesion, are convenient to dismounting.
