TECHNICAL FIELD
[0001] The utility model relates to catalyst gas modification technical field, concretely relates to a catalyst gas modification production device. BACKGROUND
[0002] Catalyst gas modification has a wide application prospect in modern industry, and its main purpose is to improve its catalytic activity, selectivity, stability and other properties by changing the surface properties and structure of the catalyst, so as to optimize the chemical reaction process, improve production efficiency, reduce cost and meet environmental protection requirements.
[0003] In the related art, the traditional catalyst gas modification production device is usually vertically arranged, but the loading capacity of the device for loading catalyst is limited, and if the loading capacity of the catalyst is large, the catalyst accumulated in the middle and bottom cannot be fully reacted with inert gas, and the heating is uneven, so that the gas modification operation of a large amount of catalyst cannot be realized, and the catalyst needs to be modified in batches, which reduces the catalyst modification efficiency.
[0004] Therefore, there is an urgent need for a catalyst gas modification production device that can meet the larger loading capacity of the catalyst and improve the catalyst modification reaction effect. UTILITY MODEL CONTENT
[0005] The utility model aims at providing a catalyst gas modification production device to solve at least one aspect of the problems and defects in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0019] As a further scheme of the present application, the intermittent atmosphere rotary kiln is provided with a temperature measuring thermocouple at one end close to the exhaust pipe.
[0020] By setting the temperature measuring thermocouple on one end of the intermittent atmosphere rotary kiln close to the exhaust pipe, the temperature in the intermittent atmosphere rotary kiln can be monitored in real time, and the heating system can be adjusted according to accurate temperature data, so that the temperature in the kiln is kept within a predetermined process range, the catalyst is uniformly heated in the kiln, local overheating or insufficient heating of the catalyst is avoided, and the catalyst modification effect is ensured.
[0021] As a further scheme of the utility model: the exhaust pipe is provided with a micro-pressure gauge.
[0022] Because the micro-pressure gauge is arranged on the exhaust pipe, the pressure in the exhaust pipe and the flow of gas in the exhaust pipe can be monitored in real time, so that the gas flow is ensured, and blockage or uneven gas flow is prevented; and the resistance problem in the gas flow can be found and solved in time, so that the stability and efficiency of the catalyst modification process are ensured.
[0023] As a further scheme of the utility model: the exhaust pipe is provided with a pressure relief valve.
[0024] By arranging the pressure relief valve on the exhaust pipe, when the pressure in the exhaust pipe exceeds the set value, the excess pressure in the kiln can be released by opening the pressure relief valve, so that the intermittent atmosphere rotary kiln is prevented from being damaged due to overpressure, the pressure stability in the intermittent atmosphere rotary kiln is ensured, and the safety and reliability of the catalyst modification process are effectively improved.
[0025] As a further scheme of the utility model: a heat preservation layer is arranged along the inner side wall of the shell.
[0026] Because the heat preservation layer is arranged along the inner side wall of the shell, the heat transfer from the inside of the intermittent atmosphere rotary kiln to the outside can be effectively reduced, the heat loss is reduced, the energy utilization efficiency is improved, the uniformity of the temperature in the shell is maintained, the temperature fluctuation is reduced, and the catalyst modification process is ensured to be carried out under stable temperature conditions.
[0027] As a further scheme of the utility model: cooling exhaust ports are arranged at both ends of the top of the shell.
[0028] By arranging the cooling exhaust ports at both ends of the top of the shell, uniform cooling of the inside of the shell can be achieved, the cooling efficiency is improved, the pressure rise in the intermittent atmosphere rotary kiln due to heat accumulation is prevented, and by promoting air circulation, the excess heat in the inside of the shell can be reduced, and the heat consistency and stability of the catalyst modification process are ensured.
