Technical Field

The invention relates to the field of coking equipment, in particular to a deformation-preventing inner wall for a pre-storage section of a dry quenching furnace.

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 invention aims to solve the technical problem of providing the dry quenching furnace inner wall which is not easy to collapse when meeting temperature change.

In order to solve the technical problems, the technical scheme adopted by the invention is as follows: 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.

By adopting the technical scheme of the invention, the following beneficial effects can be obtained:

the refractory brick of the pre-storage section deformation-preventing inner wall of the dry quenching furnace is in a temperature-changing environment with rapid cooling and rapid heating, the refractory brick is not easy to crack, the wall structure is stable, and the local collapse of the wall is not easy to cause.

Detailed Description

The embodiments of the present invention, such as the shapes and structures of the respective members, the mutual positions and connection relationships between the respective portions, the functions and operation principles of the respective portions, will be described in further detail below with reference to the accompanying drawings.

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 invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
