The cooling device is characterized in that an upper communication manifold trunk and a lower communication manifold trunk are mounted at the upper end and the lower end of an oval hopper defined by membrane type walls respectively, the upper communication manifold trunk is fixed to the lower side of an upper flange and is connected with a water outlet pipe, the lower communication manifold trunk is fixed to the upper side of a lower flange and is connected with a water inlet pipe, at least three sets of secondary heat exchangers parallel to the short radius of the oval hopper are arranged in the hopper, the two ends of a transverse manifold trunk of each secondary heat exchanger are connected with heat exchange pipes on right side membrane type walls and on reverse side membrane type walls. According to the cooling device for the materials after the calcination of the anthracite or the petroleum coke, the hopper is changed to be in the vertical state from the taper state, the volume of materials is enlarged, the front membrane type walls and the rear membrane type walls have certain radian and are connected flexibly, the number of secondary heat exchanging devices is increased, compared with the prior art, the heat exchanging efficiency can be improved, and the service life can be prolonged.
Description
Technical field
The invention belongs to the distillation apparatus of the solid-state raw material being exclusively used in specific solid-state raw material or special shape, particularly supporting with can-type calcine furnace cooling device.
Background technology
Can-type calcine furnace is applied to the destructive distillation of solid material as calcining petroleum coke become the raw material of carbon anode, calcined anthracite is become electrolgtic aluminium cathode materials, electrode paste raw material and carbon electrode raw material.Output object temperature after calcining is high needs cooling, it is even to there is inhomogeneous cooling in the type of cooling of double-layer water jacket type, effluent temperature is high, the shortcomings such as service life of equipment is short, Chinese patent CN101362951B cooling water jacket of petroleum coke can-type calcine furnace, comprise the one-level heat-exchanger rig for surrounding high-temperature material passage, described one-level heat-exchanger rig comprises an annular upper collecting chamber, and described upper collecting chamber is provided with delivery port; An annular lower header, described lower header is provided with water inlet; Many are fixedly connected with and the heat exchanger tube communicated with described lower header respectively with described upper collecting chamber; Be fixedly connected on the heat conduction baffle plate between two adjacent heat exchanger tubes.Secondary heat exchange device is provided with in the described high-temperature material passage surrounded by one-level heat-exchanger rig.This cooling jacket good rigidity, be not easy to produce thermal deformation, and heat exchange area is large, cooling heat transferring is effective.By increasing secondary heat exchange device, the uniformity of temperature of charge in whole passage is greatly improved.But it is suitable for reading large lower young that whole water jacket is reversed round bench shaped, during material (calcined coke) moves downward, there is fluffy material phenomenon, once there is fluffy material, be difficult to process.Material is large to taper cooling jacket inwall frictional force, and membrane wall is short for service life.Heat exchanger tube is vertically arrangement, and the weld bond of the large heat exchanger tube of thermal deformation and upper lower header is easily destroyed, and the little layout of inner two times heat changing device area is reasonable not, the shortcomings such as heat exchange efficiency is low.
Summary of the invention
Fluffy material phenomenon, thermal deformation is large, secondary heat exchange area is little deficiency is easily produced in order to overcome existing can-type calcine furnace cooling jacket, the invention provides refrigerating device for materials after a kind of anthracite or calcining petroleum coke, after this anthracite or calcining petroleum coke, the hopper of refrigerating device for materials changes into vertically by tapering, two sides change into up-small and down-big, increase the volume of material, front-back membrane wall has certain radian, genus flexibly connects, prevent the impact of thermal deformation butt welding mouth, add the quantity of secondary heat exchange equipment, comparatively prior art can improve heat exchange efficiency, increases the service life.
The technical solution adopted for the present invention to solve the technical problems is: refrigerating device for materials after a kind of anthracite or calcining petroleum coke, it is characterized in that: the upper and lower two ends of oval hopper surrounded by membrane wall be equipped with respectively upper connection manifold trunk with under be communicated with manifold trunk, upper connection manifold trunk to be fixed on the downside of upper flange and to be connected with outlet pipe, lower connection manifold trunk to be fixed on the upside of lower flange and to be connected with water inlet pipe, 3 groups of secondary heat exchangers parallel with oval hopper short radius are at least equipped with in hopper inside, the horizontal manifold trunk two ends of secondary heat exchanger are connected with the heat exchanger tube on obverse and reverse membrane wall respectively.
Described upper and lower connection manifold trunk is formed by connecting by two parallel supervisors and semicircular two ends pipe.
Described oval hopper obverse and reverse membrane wall is that up-small and down-big outward-dipping membrane wall epimere flexibly connects with vertical membrane wall hypomere and forms, and the membrane wall of hopper both sides is at right angle setting.
The invention has the beneficial effects as follows that the hopper owing to being surrounded by membrane wall is improved to elliptical cylinder-shape by up big and down small reverse frustoconic, and obverse and reverse is up-small and down-big, not only solve the shortcoming of the easily fluffy material of generation but also increase the volume of material, material movement speed reduces, add the time of contact of material and cooling medium, multiple secondary heat exchanger adds heat exchange area and improves heat exchange efficiency.Obverse and reverse membrane wall changes outward-dipping membrane wall epimere into and flexibly connects with vertical membrane wall hypomere and form, and substantially reduces thermal deformation stress to membrane wall and the upper and lower destruction being communicated with manifold trunk weld bond, improves the service life of equipment.
