Abstract
The invention discloses a kettle wall heat transfer mechanism for a graphite reaction kettle. The kettle wall heat transfer mechanism for the graphite reaction kettle comprises a reaction kettle body, a kettle body jacket in a tubular structure is arranged in a kettle wall of the reaction kettle body and communicated with a water inlet ring outside the kettle wall, a pipe connection hoop is arranged at the joint of the kettle body jacket and the water inlet ring, a pipe connection reinforcement ring is arranged outside the pipe connection hoop, and a pipe connection steel element hoop is arranged at the outer end of the water inlet ring. A kettle wall structure of an original graphite reaction kettle is modified by arranging the kettle body jacket in the kettle wall, and consequently the problem of reduction of integral compression strength of equipment due to insufficiency of dipping thickness is solved, thickness of a heat transfer wall is greatly reduced to improve heat transfer effects, and graphite weight is reduced. In addition, due to the graphite hoop arranged at the joint of the water inlet ring and the kettle body, the problem of leakage is solved.
Description
Technical field
The present invention relates to a kind of graphite reactor structure-improved, be specifically related to a kind of still wall heat transfer mechanism of large-scale graphite reactor.
Background technology
When designing large-scale graphite reactor, if according to design the earliest, being about to the outside that heat transfer kettle chuck is located at still wall, carrying out heat transfer.But along with the continuous amplification of reactor diameter, the calculated wall thickness of cylindrical shell increases gradually, and then increase the weight of graphite equipment, net weight has reached 25 tons, and operating weight reaches more than 30 tons, bring great difficulty, in diabatic process to transport and installation, because increasing heat transfer wall thickness, the heat-transfer effect of chuck medium also can be greatly reduced.And graphite wall thickness thickeies to a certain degree, also because of the restriction of dipping thickness, integral device compressive resistance can be affected.
Summary of the invention
Goal of the invention: the object of the invention is to solve deficiency of the prior art, thering is provided a kind of is arranged in still wall by kettle chuck, and then the problem solved because of dipping thickness deficiency reduction integral device compressive resistance, and greatly reduce heat transfer wall thickness, increase heat-transfer effect, also reduce the graphite reactor still wall heat transfer mechanism of the weight of graphite simultaneously.
Technical scheme: a kind of graphite reactor still wall heat transfer mechanism of the present invention, comprise reactor body, the kettle chuck of pipe structure is provided with in the still wall of described reactor body, described kettle chuck is communicated with the water inlet circle being located at described still wall outside, described kettle chuck and the described joint enclosed of intaking are provided with adapter circle holding, be provided with adapter stiffening ring outside described adapter circle holding, the outer end of described water inlet circle is also provided with adapter steel part circle holding.
As optimization, described kettle chuck adopts impregnated graphite structure.
As optimization, described adapter circle holding and adapter stiffening ring are graphite-structure.
As optimization, described adapter steel part circle holding adopts Q235B carbon steel structure.
As optimization, the distance range of described kettle chuck distance kettle outer wall is 110-130mm, and distance inner wall of kettle distance is 40-60mm.
Beneficial effect: the present invention's original graphite reactor still wall construction improves, kettle chuck is arranged in still wall, and then the problem solved because of dipping thickness deficiency reduction integral device compressive resistance, and greatly reduce heat transfer wall thickness, increase heat-transfer effect, also reduce the weight of graphite simultaneously.Water inlet circle is provided with graphite circle holding with the junction of kettle simultaneously, thus solves the problem of seepage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is kettle structure schematic diagram of the prior art.
Detailed description of the invention
A kind of graphite reactor still wall heat transfer mechanism as shown in Figure 1, comprise reactor body 1, the kettle chuck 5 of pipe structure is provided with in the still wall of described reactor body 1, described kettle chuck 5 is communicated with the water inlet circle 6 being located at described still wall outside, described kettle chuck 5 is provided with adapter circle holding 2 with the joint of described water inlet circle 6, be provided with adapter stiffening ring 3 outside described adapter circle holding 2, the outer end of described water inlet circle 6 is also provided with adapter steel part circle holding 4.
As the further optimization of technique scheme, described kettle chuck 5 adopts impregnated graphite structure.Described adapter circle holding 2 and adapter stiffening ring 3 are graphite-structure.Described adapter steel part circle holding 4 adopts Q235B carbon steel structure.Described kettle chuck 5 is 110-130mm apart from the distance range of kettle outer wall, is preferably 120mm, and distance inner wall of kettle distance is 40-60mm, and be preferably 50mm, radiating effect is better.
Be illustrated in figure 2 the heat transfer structure before improvement, outside still wall kettle chuck 5 being located at reactor body 1, but this design is along with the continuous amplification of reactor diameter, and the calculated wall thickness of cylindrical shell increases gradually, and then increase the weight of graphite equipment, net weight has reached 25 tons, and operating weight reaches more than 30 tons, bring great difficulty, in diabatic process to transport and installation, because increasing heat transfer wall thickness, the heat-transfer effect of chuck medium also can be greatly reduced.And graphite wall thickness thickeies to a certain degree, also because of the restriction of dipping thickness, integral device compressive resistance can be affected.
Afterwards above-mentioned heat transfer structure was improved, structure and the present invention similar, but adopt 0 type circle holding unlike circle holding, graphite reactor is in use intermittent operation, passes into emptying after steam a period of time, pass through cooling circulating water in chuck, so repeatedly operate, the tetrafluoro O type circle of water inlet circle sealing place is in the process of rising-heat contracting-cold repeatedly, and distortion allowance reduces, and easily causes seepage.
Therefore again final improvement has been carried out to said structure, i.e. the present patent application content.By cloth hole even in the middle of the graphite kettle thickeied, in guarantee, the hole of lower kettle cloth is concentric, and utilize this some holes to become the housing parts of our jacket for heat exchange, and then the problem solved because of dipping thickness deficiency reduction integral device compressive resistance, and greatly reduce heat transfer wall thickness, increase heat-transfer effect, also reduce the weight of graphite simultaneously.
(gas) circle of simultaneously intaking changes full graphite into, steel part stiffening ring carries out outsourcing and tightens up abutting edge into water circle and kettle, and then solve the problem of O type circle, simultaneously all housing jacket portion are graphite piece, the hole wall dirt caused after steam and cooling water circulation use, when equipment does not need dismounting, can be cleaned by Chemical cleaning way, add the service life of equipment.
