Description

Dry quenching furnace prestorage section anti-deformation inner wall

Technical Field

The utility model relates to a coker field, specifically speaking, the utility model relates to a put out stove prestore section deformation-preventing interior wall futilely.

Background

The coke dry quenching furnace is important equipment in a coke dry quenching process, and is frequently shut down for maintenance in the production process, the strength of a wall body is reduced due to repeated temperature rise and drop, and the wall body is extruded by coke to deform to form bulges. In order to control the combustible gas composition in the circulation system, control is generally performed by introducing cool air. The cold air, when passing through the annular duct, causes a reduction in the temperature of the refractory material. And combustible gases such as CO and H2 and the like have violent combustion reaction with the sucked air, and simultaneously emit a large amount of heat, which can cause the temperature of the refractory material to rise. The refractory brick is in a temperature changing environment with rapid cooling and rapid heating, thermal stress is generated, the strength of the brick is reduced, the brick is easy to crack, a wall structure is damaged, and local collapse is formed in severe cases.

The inner wall of the annular air duct of the dry quenching furnace is easy to deform and collapse due to the air flow scouring abrasion of coke and dust. The design of the upper layer and the lower layer of the original design of the annular air duct inner wall brick is only considered, no tongue is produced in the horizontal direction, the refractory brick is easy to generate horizontal displacement after the condition occurs, and then leaked circulating gas appears, and the annular air duct inner wall is deformed and collapsed after a long time. As shown in figure 1 below.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide a dry quenching furnace inner wall which is not easy to collapse when meeting temperature change.

In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a put out stove prestore section shape interior wall of preapring for an unfavorable turn of events futilely, includes polylith A stove brick and B stove brick, and A stove brick and B stove brick cooperate the concatenation together, the brick limit intermediate position of A stove brick sets up the arch, and another relative brick limit sets up the recess, and during the concatenation, the protruding and B stove brick recess cooperation concatenation of A stove brick forms the dry-quenching stove inner wall together.

Preferably, the dry quenching furnace further comprises a dry quenching furnace outer wall, the dry quenching furnace outer wall is arranged on the outer side of the dry quenching furnace inner wall, a plurality of support rods are arranged between the dry quenching furnace inner wall and the dry quenching furnace outer wall, and the support rods are uniformly distributed between the dry quenching furnace inner wall and the dry quenching furnace outer wall to play a supporting role.

Preferably, an expansion gap is arranged between the furnace brick protrusion A and the furnace brick groove B, and an expansion space is reserved in the expansion gap when the furnace brick expands at high temperature.

Adopt the technical scheme of the utility model, can obtain following beneficial effect:

the utility model discloses a put out stove futilely and prestore section resistant deformation interior wall resistant firebrick is in the alternating temperature environment of rapid cooling and rapid heating, and resistant firebrick is difficult to the fracture, and wall structure is firm, is difficult for causing the wall body part to collapse.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.

As shown in fig. 2, 3, this put out stove prestore section of preapring for an unfavorable turn of events shape interior wall includes polylith A stove brick 1 and B stove brick 2, and A stove brick 1 and B stove brick 2 cooperate the concatenation together, and the brick edge intermediate position of A stove brick 1 sets up the arch, and another relative brick edge sets up the recess, and during the concatenation, the protruding of A stove brick 1 cooperates the concatenation with the recess of B stove brick 2 and forms the dry-quenching stove inner wall 5 together.

As shown in FIG. 3, the outer wall 6 of the dry quenching furnace is arranged outside the inner wall 5 of the dry quenching furnace, a plurality of support rods 4 are arranged between the inner wall 5 of the dry quenching furnace and the outer wall 6 of the dry quenching furnace, and the support rods 4 are uniformly distributed between the inner wall 5 of the dry quenching furnace and the outer wall 6 of the dry quenching furnace to play a role of supporting. When the inner wall 5 of the dry quenching furnace meets rapid cooling or rapid heating, the furnace bricks shrink or expand, and the support rods 4 can play a supporting role.

As shown in figure 2, an expansion gap 3 is arranged between the bulge of the furnace brick A1 and the groove of the furnace brick B2, and an expansion space is reserved for the expansion gap 3 when the furnace brick expands at high temperature.

This put out firebrick of stove prestore section deformation-preventing inner wall futilely is in the alternating temperature environment of rapid cooling and rapid heating, and firebrick is difficult to the fracture, and wall structure is firm, is difficult for causing the wall body part to collapse.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
