Abstract
The utility model relates to a heating ammonia feeding device in the production of o-tolunitrile, belonging to the chemical product production equipment technical field. The heating ammonia feeding device is mainly characterized in that a tubular heating device is connected to the side of a reaction kettle so as to make the material heating reaction begin from the tubular heating device and complete through an ammonization kettle, thereby the flow rate of feeding and discharge is increased and the material heating reaction is sufficient and quick. Due to the function of an obviously lengthened processing line, materials are more sufficiently and completely reacted in the chemical reaction, thereby ammonia gas is almost completely absorbed and then the concentration of tail gas exhausted is reduced by 31.86 percent compared with the prior art. The heating ammonia feeding device is suitable for producing the o-tolunitrile and has obvious economic benefit and social benefit.
Description
Technical field
The utility model relates to the logical ammonia device of heating in a kind of adjacent toluic nitrile production, belongs to Chemicals production equipment technical field.
Background technology
Adjacent toluic nitrile is to make raw material with o-toluic acid, carry out ammonification by heating logical ammonia (liquefied ammonia), get product by rectifying again, existing adjacent toluic nitrile heats logical ammonia process in process of production and adopts the 3000L reactor, heats in reacting kettle jacketing, and the heating sectional area is little, bring material, overlong time in the reacting by heating has a strong impact on the raising of output, quality, consumes with " three wastes " discharging huge high-leveled and difficult following.
Summary of the invention
The purpose of this utility model provides the logical ammonia device of heating in a kind of adjacent toluic nitrile production, solve the logical ammonia process employing of heating reactor above shortcomings in the existing adjacent toluic nitrile production process, help improving adjacent toluic nitrile output, quality, reduce consumption and " three wastes " discharging in the production process.
The purpose of this utility model is achieved through the following technical solutions, the logical ammonia device of heating during a kind of adjacent toluic nitrile is produced, comprise reactor, it is characterized in that the charging of described reactor and the tubulation heating unit that the discharging interface is provided with through pipe connection, reactor is built-in with feed distributor, the charging interface of the inlet termination reactor of feed distributor.
Described tubulation heating unit is by tank body, and jar intravital tubulation stretches into feed-pipe and logical ammonia sparger formation in the tank body outside tank body.
Tank body in the described tubulation heating unit is by the loam cake with chuck, lower cover, cylindrical shell constitutes, the two ends of cylindrical shell connect solid through ring flange and upper and lower covers, cylindrical shell and loam cake, lower cover chuck adjacent are through having the pipe connection of gate valve, loam cake is connected with the charging interface of reactor through pipeline, lower cover is connected with the discharging interface of reactor through pipeline, and feed-pipe and logical ammonia sparger stretch in the lower cover of tank body outside the loam cake of tank body.
In the described tubulation heating unit tank body on cover intrinsic pressure table and thermometer, the lower cover of tank body bottom is provided with slag-drip opening, tank body lower cover bottom is provided with the oil-in and the chuck that communicates.
The straight tube that tubulation in the described tubulation heating unit is arranged side by side by some, ring flange is passed at its two ends is respectively formed.
The pipeline of tank body loam cake and reactor charging interface has chuck in the described tubulation heating unit, between two chucks through having the pipe connection of gate valve.
The utility model connects a cover tubulation heating unit by increasing on the reactor next door, and material, reacting by heating are begun from the tubulation heating unit, and finish by the reaction of ammonification still the back.Like this, the input and output material flow strengthens, material, reacting by heating are fully rapid, owing to add the time of fast response greatly, thus improved platform/time output of equipment, quality, it is also very remarkable to reduce effects such as material consumption and minimizing exhaust gas emission, and separate unit complete equipment day output improves 57% than existing apparatus now, and product content improves 1.5%, the consumption per unit product of raw materials descends 14.07% than existing apparatus, and liquefied ammonia consumption descends 22.26%; Thermo-efficiency utilizes high, and energy consumption descends obviously, and heat supply enters from the tubulation heating unit, after discharge through the ammonification still, the time ratio original device that stops with original device comparison heat supply doubles above, and the thermo-efficiency utilization is improved greatly, energy consumption obviously descends; Exhaust emissions concentration reduces, and environmental influence reduces, and can produce a large amount of waste gas in the reacting by heating process, and a large amount of ammonia of original device can not fully be absorbed and discharge from tail gas, has a strong impact on environment.The utility model is owing to the obviously effect of lengthening of technology circuit, and material more fully fully, almost completely is absorbed ammonia in chemical reaction, has descended 31.86% before now the tail gas concentration ratio of discharging changes.The utility model is applicable to the production of adjacent toluic nitrile, has remarkable economic efficiency and social benefit.
