Technical Field

The utility model relates to a chemical industry equipment technical field, concretely relates to ammonia buffer tank.

Background

In the chemical production field, the ammonia often needs to be used, and the ammonia storage tank is equipment commonly used, still need set up the ammonia buffer tank generally between ammonia storage tank and reaction unit to reach stable system pressure, guarantee the safe effect of system reaction. The process of industrially preparing ammonia gas usually comprises a gas purification process, in the process, ammonia gas is not only required to be deoxidized, but also required to be dehydrated through dehydration equipment, however, the gas in an ammonia gas buffer tank still contains a small amount of moisture, and in the long-term use process of the ammonia gas buffer tank, the moisture in the ammonia gas buffer tank can be accumulated in the buffer tank to influence the normal use of the buffer tank, in addition, in order to reduce the moisture contained in the ammonia gas, a drying device is generally required to be independently arranged at a gas outlet pipe of the buffer tank, and the occupied space is large. Therefore, an ammonia buffer tank capable of solving the existing problems is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an ammonia buffer tank that has area little, and can reduce the inside water content of ammonia to the not enough of technique.

The utility model provides a following technical scheme:

the utility model provides an ammonia buffer tank, includes the end cover and the jar body through flange joint, the jar body is including the outer jar of body with locate the internal inner tank body of the external jar of body inside, outer jar of body bottom is equipped with the fluid-discharge tube, the internal tank body bottom is opened, the internal tank body outer wall with form the cavity between the inner wall of the outer jar of body, the cavity intussuseption is filled with reproducible drier layer, the both sides of the upper end of the outer jar of body be equipped with the communicating gas inlet pipe of cavity, be equipped with on the end cover with the communicating gas outlet pipe of the inside of the internal jar.

Preferably, the bottom of the inner tank body is provided with an arc-shaped filter screen.

Preferably, the distance between the bottom of the inner tank and the inner wall of the bottom of the outer tank is 1/8-1/2 of the length of the inner tank.

Preferably, a guide plate connected with the inlet of the liquid discharge pipe is arranged below the filter screen.

Preferably, the upper end and the lower end of the cavity are respectively provided with a drying agent feeding port and a drying agent discharging port.

Preferably, the inlet of the gas outlet pipe extends to the inside of the inner tank.

Preferably, the outer surface of the outer tank body is provided with a heat-insulating layer.

The utility model has the advantages that:

the tank body of the buffer tank of the utility model is divided into an inner tank body and an outer tank body, and a drying agent layer is filled in the cavity between the outer wall of the inner tank body and the inner wall of the outer tank body, so that the buffer tank has a drying function; the ammonia gas enters from the gas inlet pipe, then enters the inner tank body after being dried by the drying agent layer, and the inlet at the bottom of the inner tank body is also provided with an arc-shaped filter screen which not only can help to slow down the circulation speed of the gas, so that the gas is more uniform in circulation, but also plays a certain role in filtering; the two gas inlet pipes are arranged so that the buffer tank is connected with a plurality of gas storage tanks; the utility model discloses compact structure, area are little.
