Problems solved by technology

However, due to the imperfection of the recovery device, fluctuations in process condensate water parameters will affect subsequent water use devices and cause losses. Therefore, general fertilizer plants discharge process condensate water directly into the environment (does not meet environmental protection discharge standards), and fail to recycle. use, water resources are wasted in vain, and it also has an impact on the environment

Embodiment Construction

[0016] Lead the process condensate water that needs to be recovered to the recovery water storage tank 1 (or other water use occasions) with pipelines, and the above four equipment required for recovery of water are online conductivity monitor 2, electric three-way valve 4, cooler 5, interlock control The system is installed on this pipeline. The conductivity meter 2 is installed on the water inlet pipeline of the three-way valve 4. One side of the three-way valve 4 leads to the recovery water storage tank, and the other side leads to the original external drainage channel. The cooler 5 is installed in the recovery water tank. Just before the water storage tank. The main control parameters are as follows:

[0017] (5) The electrical conductivity is generally required to be less than 50us / cm.

[0018] (6) The temperature is generally required to be less than 50°C.

[0019] (7) For other process parameters that are considered necessary to be set, safe values ​​can be set as lo...

Abstract

A method for recovering the technologically condensed liquid from the chemical fertilizer production apparatus features that the recovered technological condensed water is delivered into water tank via pipeline, on which the electric conductivity monitor, three-way valve, cooler and linked control system are installed. Its advantages are high safety for consuming the recovered water, and high automation level.

Description

technical field [0001] The invention relates to a method for recovering process condensate, in particular to a process for recovering process condensate of a chemical fertilizer plant. Background technique [0002] In large, medium and small chemical fertilizer plants, no matter what kind of energy is used as raw material, the common feature of the process is that the intermediate reactants of chemical fertilizer products and products contain a certain amount of water before purification, which is removed through a series of processes, Condensed water is formed after evaporation and condensation. In production, it is generally called process condensed water. The process condensed water is chemical reaction water and steam condensed water. It is very pure and can be recycled after only a little treatment. However, due to the imperfection of the recovery device, fluctuations in process condensate water parameters will affect subsequent water use devices and cause losses. There...
