Abstract
The utility model relates to a tubulation type fixed bed reactor, which is used for chemical industries. An upper fused salt outlet of the reactor and a lower fused salt inlet are provided with a circle of upper annular passages and a circle of lower annular passages outside of the circumference of reactor walls; a circle of bar shape holes with equal width and intervals and unequal height are arranged on inner walls of the annular passages, and the heights of the holes are orderly arranged from high to low along the flow direction of fused salt.
Description
The utility model is a kind of calandria type fixed bed reactor of uniform design, belongs to the technical field that chemical reactor is made.
Calandria type fixed bed reactor is widely used in the heterogeneous catalytic reaction process, this class reacts that mostly reaction speed is fast, and be to put (suction) thermal process by force, heat must be removed by reacting gas and thermophore timely and effectively, and is even with the radial temperature that guarantees thermophore between pipe.The existing large-sized calandria type fixed bed reactor radial temperature difference of China is excessive at present, and reaction selectivity is descended, and unit consumption and energy consumption increase, and the local coking of catalyst is serious, influences product quality.The distribution consistency degree of the thermophore that flows between pipe is depended in the outer temperature control of fixed bed reaction organ pipe.This is one and thermophore and the closely-related technical problem of reactor stream mechanics.Full and uniform heat transmission between how guaranteeing to manage is the key problem in technology of calandria type fixed bed reactor design.
Goal of the invention of the present utility model just provides a kind of reaction heat that makes the reactor tube outer fluid energy of flow derive rapidly and produce in the reaction tube, radially the temperature difference is as much as possible little with thermophore between the assurance pipe, each reaction tube is under the essentially identical medium temperature moves, the reactor radial temperature difference is less than 3 ℃ calandria type fixed bed reactor.
Calandria type fixed bed reactor of the present utility model mainly is made up of institutes such as reactor wall, reactor end socket, reaction tube, disc hydraulic barriers, outside the circumference of reactor wall, be provided with circular passage under circular passage and is enclosed on the circle in fused salt outlet on the reactor and following fused salt import department, it is wide, equidistantly but not contour bar hole to be provided with a circle on the inwall of circular passage, and the height in hole flows to from height to low order along fused salt and arranges.
Advantage of the present utility model is:
1. open equidistant bar hole on reactor wall, the width in hole determines, the adjusting of the height by the hole reaches equivalent shunting or the equivalent interflow of thermophore in annular flow path.
The uniform design of this reactor has realized that major diameter calandria type fixed bed reactor bed radial temperature profile is even, the temperature difference is controlled at all the time≤and 3 ℃, satisfy technological requirement.
Fig. 1 is a general structure schematic diagram of the present utility model.Following circular passage 1, annular hydraulic barrier 2, last circular passage 3, reactor end socket 4 are wherein arranged, go up fused salt outlet 5, reactor wall 6, reaction tube 7, fused salt import 9 down, circular passage outer wall 10.
Fig. 2 is the deployed configuration schematic diagram of circular passage inwall in the utility model.Bar hole 8 is wherein arranged.
Embodiment of the present utility model is as follows:
On the basis of original calandria type fixed bed reactor, position in its fused salt import and outlet, add a circle circular passage outer wall along its circumference, make this additional outer wall 10 and reactor wall 6 form a circular passage, it is wide to have a circle on the inwall of circular passage, equidistantly, its height flows to from height to low tactic bar hole 8 along fused salt.
To design 10,000 tons of/year trichloro-ethylene device ring row of channels is example:
According to annular flow path internal pressure Changing Pattern, on reactor wall, evenly offer 40 bar holes, the bar hole width is fixed, adjustable height, its height dimension sees the following form:
Annular flow path open interior height dimension (mm) on the table one
Table two time annular flow path open interior height dimension (mm)
