Embodiment 1

[0034] A heavy oil pipeline in a chemical plant needs to be cleaned and purged. First use light oil to push the heavy oil in the pipeline out of the discharge point, collect it through the floor drain to the underground oily sewage pipe network, and then purge it with 1.0MPa steam through the purge joint. Finally, blow out the stored water with compressed air. There were ear-piercing noises, diffuse steam, strong oil gas and foul smell, cross-flow of sewage, and solidified heavy oil attached to the ground.

[0035] Move a mobile chemical discharge treatment device of the present invention to the discharge point, connect the discharge point with the pipeline mixer 1a with a temporary pipeline, and connect the anticoagulant tank with the additive nozzle of the pipeline mixer 1a with a temporary pipeline Connect, use a temporary pipeline to lead the waste liquid pipe 22 to the floor drain, connect the circulating cooling water inlet and outlet pipes, fill the primary absorption a...

Embodiment 2

[0037] A safety valve was installed on the top of the sewage stripping tower of a chemical plant. Once the safety valve tripped, a large amount of steam, high-concentration hydrogen sulfide and ammonia gas were vented, causing extensive environmental pollution. The main reason is that there are corrosion leaks in the reboiler steam tube bundle at the bottom of the sewage stripper. This situation is very common, so after adjusting the operating parameters of the sewage stripper, continue to run. Causing the safety valve to trip.

[0038] When the steam tube bundle of the reboiler at the bottom of the sewage stripper has corrosion leaks and the operation of the sewage stripper fluctuates, a mobile chemical discharge treatment device of the present invention can be moved to the sewage stripper, and a temporary pipeline can be used Connect the outlet of the safety valve to the pipeline mixer 1a, use a temporary pipeline to connect the production water to the additive nozzle of the...

Abstract

The invention discloses a method and shifting unit for processing chemical-industrial emissions, belonging to the technical field of chemical-industrial environmental protection, which is used for solving the problems of disorder emission of pollutants, such as blowing-sweeping emission, emergency emptying and the like of chemical-industrial devices. According to the invention, gravity settlement, centrifugal separation and cooling separation methods are adopted to carry out gas-liquid-solid separation on the emissions, so that waste liquor and waste residue are drained according to classification; a solvent absorption method, an adsorption method and a dilution and diffusion method are adopted to carry out purification processing on drained tail gases and then the tail gases are drained according to the standard. The method and shifting unit for processing the chemical-industrial emissions also have the functions of additive-mixing, silencing and gas-conducting. According to the invention, processing equipment and connecting pipes among equipment are properly connected and then are mounted on a public chassis to form an overall device; and the overall device is combined with a shifting facility, so that the overall device can rapidly shift and be used. The method and shifting unit for processing the chemical-industrial emissions have the advantages of strong universality, good processing effect and low operating cost; some disorder emissions of the chemical-industrial devices are relatively perfectly changed into controlled order emissions; and an effective guarantee for the safe and clean production of the chemical-industrial devices is provided.

Description

technical field [0001] The invention belongs to the technical field of chemical environmental protection, and relates to a method for treating chemical discharges, in particular to a method for separating chemical discharges and treating tail gas, and a device for implementing the method. Background technique [0002] Chemical installations (including petrochemical and oil refining installations) generally have collection and treatment systems for waste gas, waste liquid, and waste residue, which conduct airtight discharge, collection, and safe treatment of the "three wastes" generated during the production process. However, due to various reasons, some chemical plants still discharge pollutants to the surrounding environment, among which the most influential ones are: start-up and shutdown maintenance and purge discharge, fault maintenance and purge discharge, production emergency venting, etc. [0003] The design of the chemical plant has considered the purging, venting an...
