Abstract

The utility model provides a high-pressure reaction tower which comprises a reaction tower (1), a material feeding pipe (2) and a material discharging pipe (3). The high-pressure reaction tower is characterized in that a heating cavity (4) is formed outside the material feeding pipe (2), an inlet (5) and an outlet (6) are formed on the heating cavity (4), and the inlet (5) is connected with the material discharging pipe. The high-pressure reaction tower provided by the utility model adopts the structure that the material discharging pipe is connected with the heating cavity, the material feeding pipe is put in the heating cavity, the energy of flashed mixture gas can be utilized to heat a reaction solution during the former procedures, so that both the energy of the mixture and the energy required by heating an ammonolysis solution are reduced. Therefore, the requirement for the equipment during the subsequent procedures is lowered, and the use amount of cold energy is greatly reduced during the ammonia recycling.

Description

High-pressure reaction tower

Technical field

The utility model relates to a kind of reaction tower, particularly high-pressure reaction tower.

Background technology

Along with economic development and scientific and technological progress, high-pressure reaction tower has obtained using widely in chemical industry.

In the prior art, in the channelization production process of aminoethane sulfonic acid, the ammonia that reactant liquor volatilizees through the high-pressure reaction tower flash distillation adds the steam temperature and can reach 160～200 ℃, after forcing cooling, with spraying absorption process it is reuptaked, the one, avoid the discharging of a large amount of ammonia to pollute, the 2nd, recycling to reduce cost.But force the cold energy source of cooling big, very high to the ability and the requirement of withstand voltage of cooling device, so utilize the heat energy of this mist to seem most important.

This patent provides a kind of device to heat with the energy that utilizes mist after the flash distillation reactant liquor to preceding working procedure, both reduce ammonia and separated the required energy of liquid heating, the energy that has reduced this mixture again makes the equipment of road, back recovery process require to reduce greatly, and the cold energy use amount when ammonia reclaims significantly reduces.

Summary of the invention

At above-mentioned defective, the high-pressure reaction tower that the utility model provides, the material efferent duct is connected heating chamber, place the material input pipe in the heating chamber, the energy that utilizes mist after the flash distillation heats the reactant liquor of preceding working procedure, both reduced ammonia and separated the required energy of liquid heating, the energy that has reduced this mixture again makes the equipment of road, back recovery process require to reduce greatly, and the cold energy use amount when ammonia reclaims significantly reduces.

The high-pressure reaction tower that the utility model provides, comprise reaction tower (1), material input pipe (2) and material efferent duct (3), the outer setting of described material input pipe (2) has heating chamber (4), this heating chamber (4) is provided with import (5) and outlet (6), and described import (5) connects material efferent duct (3).

Preferably, above-mentioned heating chamber (4) is provided with thermometer (7) and Pressure gauge (8).

The high-pressure reaction tower that the utility model provides, the material efferent duct is connected heating chamber, place the material input pipe in the heating chamber, the energy that utilizes mist after the flash distillation heats the reactant liquor of preceding working procedure, both reduce ammonia and separated the required energy of liquid heating, the energy that has reduced this mixture again makes the equipment of road, back recovery process require to reduce greatly, and the cold energy use amount when ammonia reclaims significantly reduces.

In the preferred version of utility model, heating chamber is provided with thermometer and Pressure gauge, the time data are provided, in tube side, reach the outlet temperature of technological requirement to guarantee this operation residue pipeline.
