Abstract

An inner cooled type chlorination reactor is formed by an upper sealing head with a pressure meter port H, a material feeding port A, a gas discharge port F, a liquid level meter port E and a reflux port G, a lower sealing head with a material discharge port and a cylinder body with a temperature meter port, a support lug, a sampling port and a stirrer. The cylinder body is connected with a chlorine distributor which is matched with the stirrer in the cylinder body, a heat exchange pipe is fixed on the inner wall of the cylinder body, an upper horizontal pipe and a lower horizontal pipe are provided with valves and arranged on the outer wall of the cylinder body, and the heat exchange pipe, the upper horizontal pipe and the lower horizontal pipe are connected into a whole to form a heat exchanger. The chlorine distributor directly extends into a liquid phase through a decompression shower nozzle, gas liquid reaction is uniform in mixture, gas is slowly sprayed out and spreads, and flow speed of the gas is reduced when the gas flows through a reducing section of the chloride distributor. The heat exchange pipe is a straight pipe without welding lines, so that water leakage accidents of the heat exchanger are greatly reduced. Simultaneously, a large quantity of heat produced in the reaction is carried away, so that the heat transmission effect is good. The heat exchange pipe functions as a flow guide blocking plate, so that reaction liquid can flow in the axial direction, and gas liquid contact time is increased. Simultaneously, the reactor cannot corrode equipment, thereby greatly decreasing investment of the equipment and reducing production cost.

Description

The inner-cooled chlorination reactor

Technical field

The utility model relates to a kind of chlorination reaction device, and particularly a kind of vinylidene chloride and chlorine of being used for reacts in chlorination reactor under the effect of catalyst, generates the inner-cooled chlorination reactor of the pentachloroethane mixture that contains hydrogen chloride.

Background technology

Organic chloride is a kind of important chemical product, but Different products, different production technology are also inequality to the requirement of reactor.

What Chinese patent number 200920308946.9 " the jet-propelled agitated reactors in bottom " provided only is to be used to produce the chlorination reactor that Choline Chloride uses; It is to connect shaft at the top of still body; Shaft connects paddle through the still body, and the jet air jet pipe that makes progress is arranged at the bottom of still body.

Chinese patent number 200920016250.9 " chlorination reaction devices " disclose a kind of monochloro methane and chlorine under the effect of catalyst, in chlorination reaction device, react, and generate the methane chloride mixture that contains hydrogen chloride.

The reactor of above-mentioned two patents is the production of suitable low exothermic reaction system only, and not considering the generation of reaction heat and heat dissipation problem because of it does not have cooling system.Will induce reaction overheatedly if run into strong exothermal reaction, can't distribute and security incident takes place, limitation is big, versatility is poor so use.

Summary of the invention

The utility model technical problem to be solved is: a kind of inner-cooled chlorination reactor is provided; The a large amount of heats that produce when the heat exchanger of installing on its reactor can be taken away reaction; Heat-transfer effect is good; The gas-liquid two-phase reaction is even, abundant, steady, safety, and low to the requirement of reactor manufacturing materials, greatly reduces production cost.

The utility model addresses the above problem the technical scheme that is adopted: the inner-cooled chlorination reactor; The cylindrical shell that comprises the upper cover that has pressure gauge mouth H, charging aperture A, exhaust outlet F, liquid level gauge mouth E, phegma mouth G and have the low head of discharging opening and have thermometer mouth, journal stirrup, sample tap, an agitator constitutes; Be connected with chlorine gas distributor on the said cylindrical shell and cooperate with agitator in the cylindrical shell; Be fixed with heat-exchange tube on the said cylinder inboard wall, and link into an integrated entity and constitute heat exchanger by upper lateral tube, the lower transverse tubule of band valve on heat-exchange tube and the cylinder body outer wall.

Compared with prior art, the advantage of the utility model is: this is simple in structure, and the integral body that is only connected into by upper and lower end socket and cylindrical shell is prone to make.Simple in structure and symmetrical being uniformly distributed with of chlorine gas distributor is installed in the cylindrical shell; Directly stretch in the liquid phase through the decompression shower nozzle; Gas liquid reaction is mixed and evenly slowly injection, diffusion, the reducer of gas flow rate on chlorine gas distributor reduces, and effectively prolonged the time of staying of chlorine in reactor; React more abundant, steadily safety.This chlorination reaction can produce great amount of heat, and the heat-exchange tube that constitutes heat exchanger is weldless straight tube, greatly reduces the heat exchanger leakage accident; It is good that a large amount of heats that can will react simultaneously generation are taken away heat-transfer effect; And heat-exchange tube also plays the effect of water conservancy diversion plate washer, makes reactant liquor flow increase gas-liquid contact time vertically, simultaneously also can etching apparatus; Greatly reduce investment of devices, reduced production cost; Go in the cylindrical shell to stir by the propeller agitator oblique cutting, the interior reactant liquor of reactor is mixed more evenly with gas be fully used, react safer.

The structural representation of Fig. 2, chlorine gas distributor.

The specific embodiment

Embodiment to the utility model further describes below in conjunction with accompanying drawing.

The integral body that the chlorine reaction device is connected into by upper and

lower end socket
