Description

Technical Field

[0001] The utility model belongs to the field of chemical production equipment, and specifically relates to a catalytic reactor for efficiently converting blast furnace gas into methanol production. Background Art

[0002] Blast furnace gas is a byproduct gas produced in the metallurgical industry, especially in steel production. Its main components include carbon dioxide (CO2), carbon monoxide (CO), hydrogen (H2) and a small amount of other gases. Due to the dual needs of environmental protection requirements and energy recovery, the effective utilization of blast furnace gas has become the focus of attention in the industrial field. Converting blast furnace gas into methanol is an effective way to utilize resources, which can not only reduce environmental pollution but also improve the comprehensive utilization rate of energy.

[0003] Traditionally, the conversion process of blast furnace gas to methanol uses a catalytic reactor to carry out a catalytic reaction to generate methanol. Under normal circumstances, flowing air is required in the catalytic reactor. Without flowing air, the contact between the reactant methanol and oxygen will be limited, resulting in a decrease in the efficiency of the catalytic reaction. Secondly, the chemical reaction occurring in the catalytic reactor for methanol production requires heat release. Overheating of the reactor will cause the heat inside the catalyst to be unable to be effectively dissipated, causing the catalyst temperature to rise. Excessive temperature may cause damage or failure of the catalyst. At the same time, the catalyst may be deactivated due to overheating and carbon deposition. Catalyst deactivation will further reduce the efficiency and performance of the catalytic reaction. Secondly, the stacking and placement of the catalyst will lead to a decrease in the activity of the catalyst. In addition, the tightly stacked catalyst may cause wear between the catalyst particles, further reducing the activity of the catalyst. At the same time, the poor air permeability reduces the production efficiency. Based on the above problems, this application document proposes a catalytic reactor for the efficient conversion of blast furnace gas to methanol production to improve the above problems. Utility Model Content

[0004] The utility model aims to provide a catalytic reactor for the efficient conversion of blast furnace gas into methanol production, which can regulate the flow of air in the catalytic reactor and improve the efficiency of the catalytic reaction.

The layered arrangement of the catalyst bed can reduce the bulk density of the catalyst. Secondly, the air permeability of the catalyst is enhanced, and the catalytic efficiency is improved.

[0027] Furthermore, the fan blade 16 is made of aluminum alloy, and the upper gear 13 and the lower gear 14 are made of copper alloy, wherein the aluminum alloy fan blade 16 has a high hardness, which enables the aluminum fan blade 16 to provide stable and strong wind during operation. Secondly, the aluminum alloy is not easy to deform, and can maintain its shape and performance even in the case of long-term operation or high-speed rotation, thereby having a longer service life. Copper alloy as a gear material has better impact resistance and toughness, which makes the copper alloy gear more reliable when subjected to sudden load changes. At the same time, copper alloys generally have good corrosion resistance, which extends the service life of gears. At the same time, copper alloy gears have good wear resistance, which enables copper alloy gears to maintain stability under long-term operation and repeated loads.

[0028] Furthermore, a first groove 17 is formed inside the upper tube plate 11 , and chamfered surfaces are formed at both ends of the sliding rod 15 , and the chamfered surfaces at both ends of the sliding rod 15 are matched with the first groove 17 .

[0029] like Figures 5 to 7 As shown, a plurality of fixing frames 20 are fixed in a ring shape inside the reactor shell 10, a second groove 19 is fixed between the plurality of fixing frames 20, a positioning round rod 21 is detachably sleeved inside the second groove 19, a third groove 24 is provided at the bottom end of the positioning round rod 21, a catalyst bed 22 is fixed on the outside of the positioning round rod 21, and a circular support rod 23 is fixed to the top end of the positioning round rod 21.

[0031] Furthermore, a hoisting hole is provided in the middle of the circular support rod 23, and the hoisting hole is in a square shape.

[0032] The working principle of the utility model is:

[0033] When the catalytic reactor for the efficient conversion of blast furnace gas into methanol production starts to operate, the motor 12 fixed on the upper end of the reactor shell 10 starts to operate, and the rotation of the motor 12 drives the upper gear 13 to start rotating. When the upper gear 13 rotates, it drives the lower gear 14 to rotate. A sliding rod 15 is detachably fixed inside the upper tube plate 11 and located at the bottom end of the upper gear 13. The lower gear 14 is connected to the sliding rod 15 for internal rotation. Because the fan blade 16 is fixed to the bottom end of the lower gear 14, when the lower gear 14 rotates, the fan blade 16 also rotates. The rotation of the fan blade 16 will accelerate the flow of air and further improve production efficiency. A plurality of fixing frames 20 are fixed inside the reactor shell 10. The fixing frames 20 can be used to carry a catalyst bed 22. A catalyst is placed on the catalyst bed 22. A second groove 19 is fixed between the fixing frames 20.

[0034] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
