Abstract
The utility model relates to a device for direct supplying methyl chloride to chlorination reaction in the field of production of methane chloride. The technical scheme is as follows: the device comprises a methyl chloride compressor, a chloride buffer tank, and a methyl chloride preheater which are orderly connected through a pipeline. Methyl chloride produced at a hydrochlorinate post directly enters the methyl chloride preheater to exchange heat and warm after being compressed by the compressor, and then enters a chlorination reaction system to participate into the chlorination reaction. Compared with the prior art, the steps of condensate liquefaction and evaporative gasification are removed by the device. Thus, a lot of vapor and cold flow are saved; and meanwhile, use of the device is reduced, and an operation risk is also reduced.
Description
Technical field
The utility model relates to the device of a kind of methyl chloride direct-furnish chlorination reaction in the methane chloride production field.
Background technology
At present, the methyl chloride that hydrochlorinate post, chlorocarbon workshop produces is after the methyl chloride compressor compresses, pressure is raised to 0.9Mpa, temperature 70-80 ℃, through surge tank dechlorination methane condenser condenses, the liquid phase methyl chloride dechlorination methane storage tank of condensation pumps into the methyl chloride vaporizer again and evaporates with steam heating, participates in chlorination reaction again after the methyl chloride preheater heats to 80 ℃.Uncooled gas phase methyl chloride and hydrogenchloride go the vent condenser low temperature separation process, liquid phase dechlorination methane storage tank, and gas phase de-chlorine hydride absorption system is produced hydrochloric acid.The drawback of above-mentioned design is: the gas phase methyl chloride is condensed into first liquid phase, and then heating and gasifying participation chlorination reaction, needs to consume a large amount of energy in condensation and evaporative process.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of chlorine reasonable in design, save energy pipeline displacement apparatus of giving vent to anger is provided.
Its technical scheme is: comprise the methyl chloride compressor, Chlorine Buffer Vessel, the methyl chloride preheater that connect successively by pipeline.After being the methyl chloride process compressor compresses of hydrochlorinate post production, directly entering the heat exchange of methyl chloride preheater by Chlorine Buffer Vessel and heat up, then enter chlorination system and participate in chlorination reaction.
In order to stop at chlorination system or during maintenance, do not affect the normal production in hydrochlorinate post, the connection line of described Chlorine Buffer Vessel and methyl chloride preheater is provided with take-off line, connect methyl chloride condenser, the first gas-liquid separator on it, described the first gas-liquid separator liquid exit line connects methyl chloride storage tank, the front water cooler of pump, methyl chloride pump, methyl chloride vaporizer, scum dredger, methyl chloride preheater successively; Connect successively vent condenser, the second gas-liquid separator on the outlet gas line of described the first gas-liquid separator; The liquid exit line of described the second gas-liquid separator is connected with the methyl chloride storage tank, outlet gas line is connected with the hydrogen chloride absorption device.Be after chlorination system stops, to be fluid storage with the methyl chloride condensation liquefaction, the revaporization gasification participates in chlorination reaction after driving.
Compared with prior art, the utility model has been given up the step of condensation liquefaction and evaporation gasification, has therefore saved a large amount of steam and cold; The simultaneously less use of equipment has reduced operational risk.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, a kind of device of methyl chloride direct-furnish chlorination reaction, methyl chloride compressor 1 connects Chlorine Buffer Vessel 2 by pipeline, then is divided into two-way, and one road pipeline directly connects methyl chloride preheater 3.1, then enters chlorination system; Another road pipeline connects methyl chloride condenser 4, the first gas-liquid separator 5, the first gas-liquid separator 5 liquid exit lines connect methyl chloride storage tank 6, the front water cooler 7 of pump, methyl chloride pump 8, methyl chloride vaporizer 9, scum dredger 10, methyl chloride preheater 3.2 successively, then enter chlorination system; Connect successively vent condenser 11, the second gas-liquid separator 12 on the outlet gas line of the first gas-liquid separator 5; The liquid exit line of the second gas-liquid separator 12 is connected with methyl chloride storage tank 6, outlet gas line is connected with the hydrogen chloride absorption device.
