Problems solved by technology

But both methods have serious defects; incineration consumes a lot of energy and investment, and is economically uneconomical; vaporization of the cyclone dust collector makes the dust collector easy to scale, block, corrode, and greatly reduces the service life

Embodiment 1

[0006] Example 1: A new process for the treatment of phenolic water in a gas station. First, the saturated steam generated in the gas generator is sent into the steam collecting drum for buffering, then enters the cyclone dust collector, and is heated by the cyclone dust collector to become superheated steam, superheated steam The pressure reaches 0.32MPa, and the temperature reaches 220°C; the above superheated steam enters the desuperheater, and at the same time, the phenol water stored in the intercooler is pumped into the desuperheater, and the above superheated steam and phenol water are mixed in the desuperheater Finally, new saturated steam is formed, the pressure of the new saturated steam reaches 0.32MPa, and the temperature reaches 150°C; the new saturated steam re-enters the gasifier and mixes with air as a gasification agent. React until all of them are decomposed into harmless substances.

Embodiment 2

[0007] Example 2: A new process for the treatment of phenol water in a gas station. First, the saturated steam generated in the gas generator is sent into the steam collecting drum for buffering, and then enters the cyclone dust collector, and is heated by the cyclone dust collector to become superheated steam, superheated steam The pressure reaches 0.3MPa, and the temperature reaches 240°C; the above superheated steam enters the desuperheater, and at the same time, the phenol water stored in the intercooler is pumped into the desuperheater, and the above superheated steam and phenol water are mixed in the desuperheater Finally, new saturated steam is formed, the pressure of the new saturated steam reaches 0.35MPa, and the temperature reaches 160°C; the new saturated steam re-enters the gasifier and mixes with air as a gasification agent. React until all of them are decomposed into harmless substances.

Embodiment 3

[0008] Example 3: A new process for the treatment of phenolic water in a gas station. First, the saturated steam generated in the gas generator is sent into the steam collecting drum for buffering, and then enters the cyclone dust collector. After being heated by the cyclone dust collector, it becomes superheated steam, and the superheated steam The pressure reaches 0.35MPa, and the temperature reaches 200°C; the above superheated steam enters the desuperheater, and at the same time, the phenol water stored in the intercooler is pumped into the desuperheater, and the above superheated steam and phenol water are mixed in the desuperheater Finally, new saturated steam is formed, the pressure of the new saturated steam reaches 0.3MPa, and the temperature reaches 140°C; the new saturated steam re-enters the gasifier and mixes with air as a gasification agent. When passing through the oxide layer of the gasifier, the phenol React until all of them are decomposed into harmless substa...

Abstract

The invention discloses a novel process for treating phenol water from a gas station, which comprises the following steps of: firstly delivering steam generated in a gas producer into a receiver drum for buffering the steam, enabling the steam to enter a cyclone dust collector, and heating to form overheated steam with the pressure of 0.32 MPa and the temperature of 220 DEG C by the cyclone dust collector; enabling the overheated steam to enter a desuperheater, simultaneously pumping phenol water stored in an intercooler into the desuperheater by a pump, mixing the overheated steam and the phenol water in the desuperheater to form saturated steam with the pressure of 0.32 MPa and the temperature of 150 DEG C; and enabling the saturated steam to enter the gas producer again, mixing with air as a gasification agent, and reacting phenol until completely cracking when passing through the oxidation layer of the gas producer. The invention has less investment, reliable running, high utilization rate of complementary energy and long service life of equipment.

Description

Technical field: [0001] The invention relates to a new process for treating phenol water in a gas station. Background technique: [0002] At present, there are two ways to treat the phenol-containing wastewater produced by the domestic gasifier process: one is to build an incinerator to make it burn at high temperature and crack it into a harmless product; the other is to use the waste heat of the cyclone dust collector to vaporize it into saturated steam for the furnace It can be used as a gasification agent and cracked into harmless products. But both methods have serious defects; incineration consumes a lot of energy and investment, and it is not economical; the use of cyclone dust collector vaporization makes the dust collector easy to scale, block, corrode, and the service life is greatly reduced. Invention content: [0003] The purpose of the present invention is to provide a new process for treating phenolic water in a gas station, which requires less investment, i...
