Abstract
Disclosed is a nitro chlorobenzene nitration reactor. A cooling tube is arranged in a cylinder; a first water inlet tube and a first water outlet tube which are communicated with the cooling tube are connected onto the cylinder; a feeding port and a discharging port are arranged on the upper portion of the cylinder; a stirring device is mounted at the upper end of the cylinder; a stirring component of the stirring device extends into the cylinder; a tubular jacket is spirally coiled on the outer side of the cylinder; the cross section of the tubular jacket is in the shape of an indented circle; an open side of the tubular jacket is fixed to the outer side of the cylinder; the lower end of the tubular jacket is connected with a second water inlet tube; and the upper end of the tubular jacket is connected with a second water outlet tube. After cooling water enters the tubular jacket, the tubular jacket is capable of forcing the cooling water to flow along the outer wall of the cylinder, and a flow dead zone is avoided. As the flow section of the tubular jacket is smaller, energy consumption is less, the flow velocity of the cooling water is fast, heat exchange efficiency is high, the cooling effect of the cylinder is fine, and nitration reaction temperature is low. The nitro chlorobenzene nitration reactor is reasonable and reliable in structure, and has the advantages of high heat exchange efficiency, less energy consumption, fine reaction effect and low material cost.
Description
Technical field
The utility model relates to a kind of nitration reaction still, and specifically a kind of nitro Benzene Chloride that is applicable to is carried out the agitated reactor of nitration reaction.
Background technology
Existing a kind of basic structure that is used for the agitated reactor of nitro Benzene Chloride nitration reaction is: the vertical cylindrical shell outside is with the tubular chuck; Form cavity between chuck and cylinder body outer wall; Be connected to the water inlet pipe and the outlet pipe that communicate with this cavity on the chuck; Be provided with in the cylindrical shell and be the cooling tube that coils shape more than two groups, be connected to the water inlet pipe and the outlet pipe that communicate with cooling tube on the cylindrical shell, cylindrical shell top is provided with charging aperture, discharging opening; The upper end of cylindrical shell is equipped with agitating device, and the mixing component of agitating device stretches in the cylindrical shell.Above-mentioned this agitated reactor in use exists shortcoming to be: when cooling water passed through the cavity between tubular chuck and cylinder body outer wall, the passage section of cooling water was big, flow velocity is lower, and heat exchange effect is not good enough; Cylindrical shell cooling is slower, and the temperature of nitration reaction is higher, and make that phenol is higher with the content of many nitro compounds in the product, thereby increased the difficulty of reaction product isolated, and the increase production cost.
The utility model content
The purpose of the utility model is to provide a kind of nitro Benzene Chloride nitration reaction still, and the heat exchange effect of this nitration reaction still is good, at the bottom of the reaction temperature.
Be to realize above-mentioned purpose, the utility model adopts following scheme: nitro Benzene Chloride nitration reaction still is provided with in the cylindrical shell and is the cooling tube that coils shape more than two; Be connected to first water inlet pipe and first outlet pipe that communicate with cooling tube on the cylindrical shell; Cylindrical shell top is provided with charging aperture, discharging opening, and the upper end of cylindrical shell is equipped with agitating device, and the shaft of agitating device stretches in the cylindrical shell; The shape coiling has the tubulose chuck in the shape of a spiral on the outside of cylindrical shell; The cross section of tubulose chuck is for lacking the circle shape, and the open side of tubulose chuck and the outside of cylindrical shell are fixed, and the lower end of tubulose chuck is connected to second water inlet pipe, the upper end is connected to second outlet pipe.
Visible by such scheme; The nitro Benzene Chloride nitration reaction still that the utility model provides in use; Cooling water is got in the tubulose chuck and from second outlet pipe by second water inlet pipe flow out, realize cooling, after cooling water gets in the tubulose chuck of shape coiling in the shape of a spiral cylindrical shell; But tubulose chuck forced cooling water flows along the outer wall of cylindrical shell, and does not have flow dead; Because the passage section of tubulose chuck is less, thereby, provide the energy consumption of cooling water little, the flow velocity of cooling water is fast, and heat exchange efficiency is high, the good cooling results of cylindrical shell, the temperature of nitration reaction is low.In addition, the tubulose chuck is coiled on the cylindrical shell, and reality has strengthened the intensity of cylindrical shell, therefore, the wall thickness of cylindrical shell is significantly reduced, and practices thrift the consumptive material of cylindrical shell.
The utility model is rational in infrastructure, reliable, and it has heat exchange efficiency height, energy consumption is little, reaction effect good, material cost is few characteristics.
