Embodiment Construction

[0007] The vulcanization method of a kind of new catalyst of the present invention is: add a heat exchanger between the blower fan and the heater of the converter system, add a water cooler between the heat exchanger and the blower fan, make the blower fan, heat exchanger, The heater, the converter and the water cooler form a closed circulation system; a new catalyst is installed in the converter; the fan is turned on, and the semi-water gas delivered by the fan enters the heat exchanger to exchange heat with the high-temperature semi-water gas reacted in the converter. Then it enters the heating furnace for further heating, and then enters the converter furnace for catalytic vulcanization reaction. After the reaction, it enters the heat exchanger to exchange heat with the semi-water gas newly transported by the fan to reduce the temperature. After further reducing the temperature through the water cooler, it re-enters the system circulation through the fan use.

Abstract

The invention belongs to the field of catalyst curing, and relates to a curing method of a novel catalyst, which comprises the steps that: a heat exchanger is added between a fan and a heater, a water cooler is arranged between the heat exchanger and the fan, so that the fan, the heat exchanger, the heater, a converter and the water cooler form a closed circulating system, and the novel catalyst is arranged in the converter; and the fan is turned on to convey semi-water gas into the closed circulating system to carry out catalyst curing reaction. The method separates a catalyst curing process from a large system to form the closed catalyst curing system, so that reaction gas is effectively recovered and is not emitted, energy is saved, environment is protected, the safety factor is high, and the production of a whole synthetic ammonia system is not affected.

Description

technical field [0001] The invention belongs to the field of catalyst vulcanization, in particular to a new catalyst vulcanization method. Background technique [0002] In the full low-voltage conversion process, when adding catalyst or replacing waste catalyst in order to increase production output, the whole system needs to be shut down, and the process of catalyst loading and original vulcanization is long, which takes at least 10 days to complete, which directly affects production; at the same time, during the vulcanization process The amount of gas used is large, and the used gas is mostly vented or ignited directly, which pollutes the atmosphere, wastes resources, does not meet the standards of energy conservation and emission reduction, and has a low safety factor for venting and ignition operations, which has many disadvantages. Contents of the invention [0003] The purpose of the present invention is to provide a new catalyst vulcanization method to solve the pro...
