Abstract
It the utility model is related to a kind of ammonia malleation absorption plant, it is characterised in that：Including first pressure valve group, second pressure valve group, the 3rd pressure valve group, the first valve, the second valve and the 3rd valve；The operating pressure of the first pressure valve group, second pressure valve group and the 3rd pressure valve group gradually increases；The top installation pressure valve group of scrubbing tower, during use after ammonia, which is let out, puts scrubbing tower, start to absorb under 0.05MPa operating modes, after the substantial amounts of ammonia of absorption tends to saturation, 0.05MPa pressure valve take-off, 0.10 MPa pressure valve is started working, by that analogy, after scrubbing tower absorbs ammonia to 0.20MPa, surface washing tower absorbs ammonia and is in 0.20MPa direct draughts, absorb ammonia saturation, ammoniacal liquor solubility is also higher, after 0.20MPa, to ensure that scrubbing tower is safe to use, 0.20MPa pressure valve is opened, the ammonia exceeded is further absorbed by vent gas treatment tower；The absorption efficiency and ammonia that have detected ammonia absorb pressure ring border.
Description
Technical field
It the utility model is related to chemical production field, more particularly to a kind of ammonia malleation absorption plant.
Background technology
In ammonification production process, the relationship between efficiency of the absorption of ammonia is to cost accounting and environment, it is necessary to set out one kind just
Press absorption plant；Scrubbing tower top install pressure valve group, pressure valve design pressure be respectively 0.05MPa, 0.10MPa,
During 0.20MPa, use after ammonia is let out and puts scrubbing tower, start to absorb under 0.05MPa operating modes, when the substantial amounts of ammonia of absorption
After tending to saturation, 0.05MPa safety valve jumping up, 0.10 MPa pressure valve is started working, and tends to be full when absorbing substantial amounts of ammonia
With it is rear, 0.10MPa after absorbing substantial amounts of ammonia and tending to saturation, start working by pressure valve take-off, 0.20MPa safety valves, when washing
Wash tower and absorb ammonia to after 0.20MPa, surface washing tower absorbs ammonia and be in 0.20MPa direct draughts, and absorption ammonia is
Saturation, ammoniacal liquor solubility is also higher, and after 0.20MPa, to ensure that scrubbing tower is safe to use, 0.20MPa pressure valve is opened, and is exceeded
Ammonia further absorbed by vent gas treatment tower.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of efficiency for the absorption that can detect ammonia and work is pressed
The ammonia malleation absorption plant of power.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of ammonia malleation absorption plant, the ammonia
Malleation absorption plant is arranged on ammonia scrubbing tower, and ammonia scrubbing tower is connected by pipeline with vent gas treatment tower；Its innovative point exists
In：Including first pressure valve group, second pressure valve group, the 3rd pressure valve group, the first valve, the second valve and the 3rd valve；Institute
The operating pressure for stating first pressure valve group, second pressure valve group and the 3rd pressure valve group gradually increases；
The first valve is provided with the pipeline that the ammonia scrubbing tower is connected with vent gas treatment tower；The first pressure valve
Group, second pressure valve group and the 3rd pressure valve group are arranged in parallel to form pressure valve group shunt circuit successively；The pressure valve group is in parallel
The input in loop is connected by the second valve with ammonia scrubbing tower, and the output end of the pressure valve group shunt circuit passes through the 3rd valve
Door is connected with vent gas treatment tower.
Further, the operating pressure of the first pressure valve group is 0.05MPa；The operating pressure of second pressure valve group is
0.1MPa；The operating pressure of 3rd pressure valve group is 0.2MPa.
Further, second valve and the 3rd valve are respectively positioned on pressure valve group shunt circuit.
The utility model has the advantage of：
1）In the utility model scrubbing tower top install pressure valve group, pressure valve design pressure be respectively 0.05MPa,
During 0.10MPa, 0.20MPa, use after ammonia is let out and puts scrubbing tower, start to absorb under 0.05MPa operating modes, it is big when absorbing
After the ammonia of amount tends to saturation, 0.05MPa safety valve jumping up, 0.10 MPa pressure valve is started working, when the substantial amounts of ammonia of absorption
After gas tends to saturation, for 0.10MPa after the substantial amounts of ammonia of absorption tends to saturation, safety valve jumping up, 0.20MPa pressure valve starts work
Make, after scrubbing tower absorbs ammonia to 0.20MPa, surface washing tower absorbs ammonia and is in 0.20MPa direct draughts, absorbing ammonia
Gas saturation, ammoniacal liquor solubility is also higher, and after 0.20MPa, to ensure that scrubbing tower is safe to use, 0.20MPa pressure valve is opened
Open, the ammonia exceeded is further absorbed by vent gas treatment tower；The absorption efficiency and ammonia that have detected ammonia absorb pressure ring border.
