Abstract
The utility model relates to a novel cold hydrogen disc, which is fixedly arranged on a support ring of a coal tar hydrogenation reactor. The cold hydrogen disc is characterized in that three layers of plates, namely an upper layer of plate, a middle layer of plate and a lower layer of plate, are spliced and connected into a whole, wherein on the upper layer of plate, small plate blocks are spliced through fastening pieces to form a whole throttle plate, and two symmetrical throttling holes are formed on the throttle plate; swirl channels are formed between the upper layer of plate and the lower layer of plate, and divided into two groups and communicated with the throttling holes on the upper layer of throttle plate; a central hole communicated with the lower layer of plate is formed in the middle of the middle layer of plate; and the lower layer of plate is a distributing disc, and through holes are uniformly distributed on the distributing disc. As an efficient internal member of the hydrogenation reactor, the novel cold hydrogen disc is a novel structural style, and has the advantages of better application effect on the coal tar hydrogenation reactor, uniform media distribution and complete mixing of coal tar and cold hydrogen.
Description
Technical field
The utility model relates to coal tar hydrogenating unit, refers in particular to utilize coal tar hydrogenation in reactor, by the manufacture a finished product cold hydrogen dish of the required main internals hydrogenator of oil of catalyst reaction.
Background technology
At present, coal and relevant industries thereof produce a large amount of byproduct coal tar, owing to contain a large amount of sulphur and other impurity in the coal tar, domestic modal way is with the coal tar burning that acts as a fuel, and has caused the loss of environmental pollution and economic benefit like this.
Summary of the invention
The purpose of this utility model is improved, is innovated at shortcoming that exists in the background technology and problem, and a kind of simple in structure, effective novel cold hydrogen dish is provided.
The technical solution of the utility model is the cold hydrogen dish on a kind of supporting cup that is fixedly installed on the coal tar hydrogenating reactor of structure, and it is in aggregates that it connects assembly unit by the upper, middle and lower-ranking plank frame, wherein:
The upper strata is that small piece plate is spliced into a monoblock throttle plate by fastening piece, has symmetric two throttle orifices on the throttle plate;
The eddy flow passage is set between upper strata and the la m, and the eddy flow passage is left and right two groups, and the throttle orifice of eddy flow passage and upper strata throttle plate connects;
Described la m middle part also has a centre hole that connects with lower plywood;
Described lower plywood is a distributing disc, has through hole on the distributing disc uniformly.
The utility model has following advantage and beneficial effect:
The utility model is the efficient internals of hydrogenator, makes the cold hydrogen dish thorough mixing of medium process by the reactor upper bed layer, reaches the purpose of reaction and to reduce temperature of charge, satisfies the reaction requirement of next beds, guarantees to react and carries out smoothly.The utility model is a kind of novel structural shape, and effect is better on the coal tar hydrogenating reactor, the medium distributed uniform, and coal tar mixes fully with cold hydrogen.

Embodiment
By Fig. 1 to 4 as can be known, the utility model is fixedly installed on the supporting cup of coal tar hydrogenating reactor 7, and it is in aggregates that it connects assembly unit by the upper, middle and lower-ranking plank frame, wherein:
The upper strata is that small piece plate is spliced into a monoblock throttle plate 1 by fastening piece, has symmetric two throttle orifices 2 on the throttle plate 1;
Eddy flow passage 3 is set between upper strata and the la m, and eddy flow passage 3 is left and right two groups, and eddy flow passage 3 connects with the throttle orifice 2 of upper strata throttle plate 1;
Described la m middle part also has a centre hole 4 that connects with lower plywood;
Described lower plywood is a distributing disc 5, has through hole 6 on the distributing disc 5 uniformly.
Through hole 6 described in the utility model is covered with whole distributing disc 5, and the through hole 6 at middle part is aperture, and through hole 6 all around is a macropore.Described eddy flow passage 3 is welded for top plate, la m and central dividing plate.The size of described throttle orifice 2 can be adjusted.
Principle of work of the present utility model:
The utility model is the place that the caloric response thing carries out thermal exchange in the hydrogenator, its effect is that the thermal response thing that upper bed layer is flow down mixes fully with the cold hydrogen that is injected by cold hydrogen tube, to reduce temperature of charge, satisfy the reaction requirement of next beds, guarantee to react and carry out smoothly.Liquid Flow situation in the cold hydrogen dish: the biphase gas and liquid flow that flows down from top is before entering throttle orifice, major part accumulates on the liquid collecting plate, form a thick layer of liquid, when cold hydrogen sprays in cold hydrogen tube, consumingly the liquid layer on the liquid collecting plate is dispelled, part liquid along continuous straight runs is pushed barrel to, plays the premix effect.Gas-liquid is dashed to the eddy flow channel base plate after throttle orifice penetrates, and the liquid disturbance is reinforced, and has produced to splash and vortex, enters then in the eddy flow passage, produces eddy flow, has prolonged mixing time.In eddy flow, mix, enter interstitial hole then, flow on the distributing disc, gas-liquid is further contacted, reach the purpose of thermal exchange.The distribution hole that last gas-liquid communicated on the distributing disc is distributed down.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that the utility model design and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; engineering technical personnel make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
