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
The invention belongs to catalyst sulfuration field, relate in particular to a kind of vulcanization process of new catalyst.
Background technology
Become in the conversion process in order to improve production output and need to add catalyst or change waste and old catalyst complete low, need total system to stop, and process such as the original sulfuration of catalyst filling is long, need at least could accomplish in about 10 days, directly influence production; Simultaneously the coal gas use amount is big in the sulfidation, many directly emptying of the coal gas after the use or light, and atmosphere pollution, the waste resource does not meet the standard of energy-saving and emission-reduction, and the safety coefficient of emptying ignition operation is low, has many drawbacks.
Summary of the invention
The vulcanization process that the purpose of this invention is to provide a kind of new catalyst, when solving newly-increased catalyst or changing old catalyst, down time long production and the low problem of the original sulfuration waste resource resource security of new catalyst of influencing.
For realizing above-mentioned purpose; The vulcanization process of a kind of new catalyst of the present invention is: newly-increased heat exchanger between the blower fan of change furnace system and heater; Newly-increased water cooler between heat exchanger and the blower fan makes blower fan, heat exchanger, heater, change furnace, water cooler form the circulatory system of a sealing; New catalyst is installed in change furnace; Open blower fan; The semiwater gas that blower fan is carried gets into reacted high temperature semiwater gas heat exchange in heat exchanger and the change furnace, gets into heating furnace after the heat exchange and further heats, and gets into change furnace afterwards and carries out the catalyst vulcanization reaction; The reaction back gets into heat exchanger and the new semiwater gas heat exchange of carrying of blower fan; Reduce temperature, further reduce temperature through water cooler then after, get into systemic circulation again through blower fan and use.
Adopt the inventive method, on original transformation system basis, incorporate heat exchanger and water cooler into, and form the circulatory system of sealing through pipeline; The low temperature semiwater gas gets into blower fan along pipeline, is transported to heat exchanger through blower fan, with reacted coal gas of high temperature heat exchange in change furnace; Improve the temperature of low temperature coal gas, low temperature coal gas gets into heater and is heated to the required temperature of vulcanization reaction after the heat exchanger heat exchange; Because before getting into heater; Low temperature coal gas has improved temperature in heat exchanger, so practiced thrift the energy consumption that heater is used to heat to a great extent, practiced thrift the energy; Simultaneously, the coal gas of high temperature behind the vulcanization reaction is through after the heat exchanger heat exchange, and temperature reduces; And further lower the temperature through water cooler, recycling through the blower fan access to plant once more through the coal gas pipeloop, water cooler is to the further cooling of coal gas of high temperature; Can prevent the damage of high-temperature gas to blower fan; Prolong equipment life, the recycle of coal gas has solved coal gas and has used directly low, the air-polluting problem of emptying igniting security of back, and has avoided the wasting of resources.
The advantage of the inventive method is, can from the big system of whole synthetic ammonia, separate the catalyst sulfidation, forms an independently totally enclosed type curing system, and coal gas effectively reclaims does not have discharging, and energy-conserving and environment-protective are safe and reliable; Carry out owing to from synthesis ammonia system, separating sulfidation simultaneously, thereby reduce the influence of catalyst sulfuration the production efficiency of big system.
The specific embodiment
The vulcanization process of a kind of new catalyst of the present invention is: newly-increased heat exchanger between the blower fan of change furnace system and heater; Newly-increased water cooler between heat exchanger and the blower fan makes blower fan, heat exchanger, heater, change furnace, water cooler form the circulatory system of a sealing; New catalyst is installed in change furnace; Open blower fan; The semiwater gas that blower fan is carried gets into reacted high temperature semiwater gas heat exchange in heat exchanger and the change furnace, gets into heating furnace after the heat exchange and further heats, and gets into change furnace afterwards and carries out the catalyst vulcanization reaction; The reaction back gets into heat exchanger and the new semiwater gas heat exchange of carrying of blower fan; Reduce temperature, further reduce temperature through water cooler then after, get into systemic circulation again through blower fan and use.
Claims (1)
1. the vulcanization process of a new catalyst; It is characterized in that: newly-increased heat exchanger between the blower fan of change furnace system and heater; Newly-increased water cooler between heat exchanger and the blower fan makes blower fan, heat exchanger, heater, change furnace, water cooler form the circulatory system of a sealing; New catalyst is installed in change furnace; Open blower fan; The semiwater gas that blower fan is carried gets into reacted high temperature semiwater gas heat exchange in heat exchanger and the change furnace, gets into heating furnace after the heat exchange and further heats, and gets into change furnace afterwards and carries out the catalyst vulcanization reaction; The reaction back gets into heat exchanger and the new semiwater gas heat exchange of carrying of blower fan; Reduce temperature, further reduce temperature through water cooler then after, get into systemic circulation again through blower fan and use.
