All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.

Examples:

as shown in fig. 1-4, a novel spiral catalytic reaction apparatus comprises: a sleeve core, a solenoid reaction unit and a solenoid sleeve.

In particular, the device can be externally provided with a spiral catalytic net and an electric heating pipe, and is convenient to detach and replace. The spiral reaction tube can be plugged with a metal catalytic net with a net-shaped structure for supporting a catalyst. The electric heating pipe can be inserted into the electric heating hole.

The solenoid sleeve and the sleeve core are made of ceramic materials.

A solenoid housing for housing the solenoid reaction unit and the core, the solenoid housing being located at an outermost layer; consists of two semi-cylindrical shell structures, wherein a plurality of turns of thread grooves are distributed on the inner side of the semi-cylindrical shell structures;

and a groove for closely fitting the solenoid reaction unit to the solenoid housing.

In particular, the solenoid sleeve is made of high-temperature resistant materials, so that the solenoid sleeve is safer to use; in particular, the solenoid valve sleeve not only can protect the solenoid reaction unit inside, but also plays a role in heat preservation, so that the electric heating pipe has higher heating efficiency and promotes the full reaction of reactants.

The sleeve core is provided with a round hole along the axial direction, is an electric heating hole and is additionally provided with an electric heating pipe in a plugging manner;

a solenoid reaction unit (i.e., a combination of solenoid reaction tubes) for circulating the reaction monomers.

The solenoid reaction unit is formed by alternately winding 6 identical solenoid reaction pipes along the radial direction to form seamless embedded combination, and is embedded at the outer side of the sleeve core and the inner side of the solenoid sleeve to form axicentral symmetry;

the spiral reaction tube is alternately wound to realize layering, so that the spiral reaction tube is used for carrying out cyclic reaction and multiple catalytic reactions;

the spiral reaction tube is a solenoid with two ends open along the axial direction. The combination mode can ensure that 6 spiral reaction tubes can be tightly attached together without gaps, when the device vibrates, the spiral reaction tubes are protected, because the spiral reaction tubes are provided with gaps, the device is easy to damage during vibration, the spiral reaction tubes are free from gaps, the damage can be prevented, and the spiral reaction tubes are convenient to detach.

In particular, the coil height of the spiral reaction tube is equal to 6 times the diameter of the spiral reaction tube, so that 6 spiral reaction tubes are seamlessly combined into a spiral reaction unit.

The two ends of the solenoid reaction unit are bent along the radial direction, and the bending lengths are kept consistent, so that the ports of the solenoid reaction unit are axisymmetric.

The spiral reaction tube is spirally wound, so that the total length is longer than that of the straight reaction tube, the reaction time of reactants is further prolonged, and the reactants can react more fully by repeatedly carrying out the reaction round by round along the spiral reaction tube. The alternating winding of the solenoid reaction units achieves layering for carrying out cyclic reactions as well as multiple catalytic reactions.

The implementation process of the cyclic reaction comprises the following steps: the materials are processed, the materials are fed from the bottom of the device through a feeding device, the carriers are added at the same time, and the materials enter a spiral catalytic net in a solenoid reaction unit and are heated through an electric heating pipe to react. Because the single spiral reaction tube is formed by winding 6 spiral reaction tubes together, the spiral reaction tube is internally layered by winding, and the reactants can be circularly reacted, so that the reactants can reach the maximum conversion rate and reach the equilibrium state. For example: nitrogen and hydrogen produce ammonia under the action of high-temperature and high-pressure catalyst. The nitrogen and the hydrogen are added from the bottom of the device through the feeding device and simultaneously added into the carrier for reaction, and after ammonia gas is generated, if the reaction is not completely carried out, the next reaction can be carried out, so that the reaction is circulated until the reaction reaches an equilibrium state.

The realization process of a plurality of catalytic reactions comprises the following steps: the solenoid reaction unit may be divided into two or more parts to perform different reactions in different parts. For example, the catalyst is divided into two parts, and the liquid level is used as a dividing line, for example, normal hexane is subjected to cracking reaction under the action of the catalyst below the liquid level to generate propylene and propane. And (3) carrying out catalytic hydrogenation reaction on propylene above the liquid level to generate propane.

The spiral reaction tube may perform various forms of single-phase or multi-phase reactions. In particular, heterogeneous reaction can be carried out, solid-liquid, solid-gas and gas-liquid reaction is realized, the device has wide application range and strong practicability, and a reaction environment with higher quality is created for reactants. The device can realize complex heterogeneous catalytic reaction, for example, when a horizontally placed spiral reaction tube is filled with part of liquid, the cavity of the spiral reaction tube can form two alternately connected phases, namely gas phase and liquid phase, and when the gas passing through the spiral reaction tube passes through the spiral reaction tube, the catalyst of the gas phase and the liquid phase alternately occurs, so that the aim of generating a product more optimally is achieved. In addition to the gas-liquid phase reaction, a gas-solid phase reaction or a liquid-solid phase reaction can be similarly carried out.

The solenoid sleeve consists of two semi-cylindrical shell structures, and a plurality of turns of grooves are distributed on the inner side of the solenoid sleeve;

The catalytic net translates in the solenoid reaction unit and enriches the catalyst.

Specifically, the catalytic net is a net structure made of metal and is placed in the solenoid reaction unit, and different catalysts can be placed on the catalytic net according to different reactions so that the reactions can be more orderly carried out. The placement of different catalysts on the catalytic mesh allows the catalyst to be attached to the metal mesh using a static process. For example: the simple substance of aluminum and sodium hydroxide solution are placed in a solenoid to react to generate aluminum hydroxide, the generated aluminum hydroxide is heated to generate aluminum oxide and water, the aluminum oxide catalyst is attached to a catalytic net through standing, and finally the generated water is poured out to perform subsequent reactions.

In particular, the device can control the reaction conditions (such as temperature, pressure and the like), thereby controlling the ratio of reactants. And the material which is difficult to react can be circularly reacted, so that the conversion rate of the material is improved. The device can simultaneously carry out a plurality of catalytic reactions and can adapt to the reactions under different conditions. Saving cost and time.

The above embodiments are merely illustrative of the preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but various modifications and improvements made by those skilled in the art to which the present utility model pertains are made without departing from the spirit of the present utility model, and all modifications and improvements fall within the scope of the present utility model as defined in the appended claims.
