Description
Technical field
The utility model relates to a kind of reactor, specifically a kind of conversion reactor that is generated vinyl chloride by acetylene, hydrogen chloride gas conversion reaction.
Background technology
In carbide, produce in the production process of polyvinyl chloride, the mist being comprised of acetylene and hydrogen chloride reacts production vinyl chloride through take the converter that active carbon is catalyst as carrier mercury chloride.This reaction is exothermic reaction, in reaction, can produce a large amount of reaction heat.Too high temperature can cause the volatilization of mercury and then cause catalyst to lose efficacy, and makes its devitalization, and the discharge of mercury simultaneously not only increases production cost, also can cause environmental pollution.
Traditional vinyl chloride conversion reactor is exactly a tubular heat exchanger, the activity carbon carrier that contains mercuric chloride catalyst is placed in tube side, when the mist being comprised of acetylene and hydrogen chloride is flowed through tube side, under catalysis, react, the water of the heat producing in reaction in shell side is taken away, in course of reaction, need to make the temperature in tube side to be maintained within a certain range, to prevent excess Temperature, cause catalyst to consume situation generation high, the too low impact reaction of temperature.
Because the heat producing in this conversion reaction is many, can the heat that therefore reaction is produced be taken away is as early as possible a major criterion that embodies reactor quality.For tubular heat exchanger, in the situation that instrument size is constant, want to increase heat exchange area, can only reduce heat exchanger tube diameter, or reduce the distance between heat exchanger tube.Owing to also will depositing catalyst and carrier in heat exchanger tube, so caliber can not too little (picking and placeing of inconvenient catalyst); In order to ensure weld strength, the distance between heat exchanger tube can not be too little.Consider, present stage heat exchange tube diameter minimum accomplish φ 45 ㎜, heat exchanger tube centre-to-centre spacing is generally 57mm.
In actual production, often because mist dehydration does not cause catalyst and carrier caking only, thereby stop up tube side passage, impact reaction is carried out.The catalyst stopping up on the other hand and the removing of carrier are also more difficult.Once dry hydrogen chloride gas runs into water and becomes hydrochloric acid simultaneously, will be very soon by equipment corrosion, once some local leakages, whole equipment will be scrapped.
In sum, it is low that existing conversion reactor has heat exchange efficiency, and catalyst and carrier are difficult to the problem of changing, caking cleaning is difficult.
Utility model content:
After the purpose of this utility model is to provide a kind of both high efficient heat exchangings and catalyst is changed conveniently, lumpd, be easy to the vinyl chloride conversion reactor of cleaning.
The utility model is achieved in that
Vinyl chloride conversion reactor comprises reaction warehouse, is installed on the heat-exchanger rig in reaction warehouse; Upper collector tube, lower collector tube that described heat-exchanger rig comprises spaced apart some vertical heat exchanger plates of putting, joins with liquid outlet, the inlet of described each heat exchanger plates; On described upper collector tube, lower collector tube, offer refrigerant exit, refrigerant import; Described heat exchanger plates, upper collector tube, lower liquid collecting pipe form refrigerant passage; Between described spaced apart heat exchanger plates, form and take activated carbon and take the catalyst storehouse that mercury chloride is catalyst as carrier; The end opening of described reaction warehouse is the air inlet of acetylene and chlorine hydride mixed gas body, and the suitable for reading of described reaction warehouse is the gas outlet of vinyl chloride gas.
In the utility model, the described vertical heat exchanger plates of putting is welded by two heat exchanger plates.
In the utility model, described reaction warehouse bottom is provided with for supporting the gripper shoe of heat exchanger plates and mercuric chloride catalyst.
In the utility model, reaction warehouse side arranges with gemel access door.
In the utility model, between the liquid outlet of described each heat exchanger plates, inlet and the upper collector tube joining, lower collector tube, adopt flexible pipe to be connected, to facilitate the spacing of adjusting between heat exchanger plates.
The utility model adopts plate type heat exchanger, and heat exchanger plates adopts all-welded structure, has avoided the leakage problem of chilled water, correspondingly, has also just avoided hydrogen chloride gas to meet the etching problem producing after water.In reaction warehouse of the present utility model, because catalyst is placed between two heat exchanger plates, therefore, can by the spacing of adjusting between heat exchanger plates, make it to adapt to picking and placeing of catalyst easily.The in the situation that of reaction warehouse given volume, the less heat exchange area of heat exchanger plates spacing is larger.The spacing of heat exchanger plates picks and places convenient setting according to catalyst, and need not consider equipment intensity.As long as abundant interface is set on collector tube, increase and decrease arbitrarily in the situation that amount of heat exchanger plates can allowing in reaction warehouse space, thus reach the object that increases and decreases heat exchange area.
Meanwhile, the hinge type hermatic door of installing in reaction warehouse is convenient to installation, the dismounting of heat exchanger plates, has also solved catalyst and the carrier not problem of easy to clean of luming.If a slice heat exchanger plates damages dismountable replacing, do not affect Whole Equipment operation and use.

Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
Shown in Fig. 1, vinyl chloride conversion reactor comprises reaction warehouse 10, is installed on the heat-exchanger rig in reaction warehouse 10; Upper collector tube 2, lower collector tube 5 that described heat-exchanger rig comprises spaced apart some vertical heat exchanger plates 4 of putting, joins with liquid outlet, the inlet of described each heat exchanger plates; On described upper collector tube 2, offer refrigerant exit 8, on described lower collector tube 5, offer refrigerant import 7; Described heat exchanger plates 4, upper collector tube 2, lower collector tube 5 form refrigerant passage; Between described spaced apart heat exchanger plates, form and take activated carbon and take the catalyst storehouse 1 that mercury chloride is catalyst as carrier; The end opening of described reaction warehouse is the air inlet 6 of acetylene and chlorine hydride mixed gas body, and the suitable for reading of described reaction warehouse is the gas outlet 9 of vinyl chloride gas.The described vertical heat exchanger plates of putting is welded by two heat exchanger plates.Described reaction warehouse 1 bottom is provided with the gripper shoe (not shown) for supporting heat exchanger plates 4 and mercuric chloride catalyst.Described reaction warehouse side arranges with gemel access door, is convenient to change maintenance heat exchanger plates and removes inner catalyst and carrier.Between the liquid outlet of described each heat exchanger plates, inlet and the upper collector tube joining, lower collector tube, adopt flexible pipe to be connected.In this vinyl chloride conversion reactor, on reaction warehouse sidewall suitable for reading, offer catalyst dog-house 3.
When the specific concave, convex point processing on heat exchanger plates of the present utility model is used for increasing heat exchange area and heat exchange efficiency, also increased the intensity of heat exchanger plates.The big or small depth of concave, convex point designs as the heap filling density of catalyst and carrier, angle of repose etc. according to the characteristic of catalyst and carrier.Meanwhile, the refrigerant fluid in heat exchanger plates and the reacting gas between heat exchanger plates are in flow process, and because the sags and crests on heat exchanger plates exists, turbulence state is better, and heat exchange efficiency is higher.Reaction warehouse peripheral hardware refrigerant pipe, for the turnover of refrigerant in heat exchanger plates.
The utility model has solved the problem that existing plate type heat exchanger is only applicable to liquid, liquid heat exchange, applicable to the heat transfer process of liquid, liquid heat exchange and solid, liquid storeroom.
