Embodiment 1

[0036] Such as figure 1 As shown, a fully sealed environmental protection recovery control system for coal coke tar slag in this embodiment includes an emulsifier 100, a two-phase separator 200 and a tar slag tank 300, wherein the emulsifier 100 is covered with a thermal insulation container 110, and The top and the bottom of the insulated container 110 are respectively provided with an insulated container liquid outlet 103 and an insulated container liquid inlet 104, and the top of the emulsifier 100 is provided with a feeding port 101; Sealed tube 102, the bottom of the emulsifier 100 is provided with an outlet, the outlet is connected to the two-phase separator 200 through a pipeline, the top of the two-phase separator 200 is provided with a waste gas outlet 201, and one side is provided with a discharge port 202, the two-phase separator There is a slag outlet 203 at the bottom of the 200, and the slag outlet 203 discharges the tar residue through the slag outlet pipe 204. ...

Embodiment 2

[0047] A fully sealed environment-friendly recovery control system for coal coke chemical tar residue in this embodiment is basically the same as in Embodiment 1. Furthermore, in this embodiment, the emulsifier 100 is also equipped with a device for cleaning and purging the passive liquid level switch 120 The switch purge 121, as figure 1 As shown, the switch purger 121 is obliquely arranged on the side of the passive liquid level switch 120 , and its height gradually decreases along the direction of approaching the passive liquid level switch 120 . And if figure 2 As shown, switch purgers 121 are respectively provided on both sides of the passive liquid level switch 120, and at least one switch purger 121 is purged with ammonia water. Specifically, the two sides are symmetrically arranged and distributed at an angle of 90°. One side is purged with high-temperature steam, and the other side is purged with ammonia water, which can prevent the solidification of oil residue and...

Embodiment 3

[0049] A fully sealed environment-friendly recovery control system for coal coke chemical tar slag in this embodiment is basically the same as the above-mentioned embodiment. Furthermore, in this embodiment, a protective plate 130 is also provided in the emulsifier 100, and the protective plate 130 is covered in an airless above the source liquid level switch 120 , and the protective plate 130 gradually slopes downward along the direction away from the inner wall of the emulsifier 100 . Such as figure 1 As shown, the protection plate 130 can be set to be similar to an L shape, and its horizontal extension section is set above the passive liquid level switch 120, and then its end is gradually inclined downward, so as to facilitate the tar residue to slide down and prevent the tar residue from dripping and sticking. Attached to the passive liquid level switch 120; a protective plate purger 131 is arranged above the protective plate 130, and the protective plate purger 131 gradua...

Abstract

The invention discloses a fully-sealed environmentally-friendly recovery control system for tar residues in the coal tar chemical industry, and belongs to the field of pollution treatment. The systemcomprises an emulsifier, a two-phase separator and a tar residue tank, wherein a passive liquid level switch is arranged in the emulsifier, the outlet of the emulsifier is connected with the two-phaseseparator through a pipeline, and an eccentric ball valve, a grinding pump and a conveying pump are arranged on the outlet pipeline; and a sealing cover sleeves the outer side of a slag outlet pipe at the bottom of the two-phase separator in a fit manner, is connected with a driving arm, is driven by the driving arm to lift up and down, and is used for sealing the top opening of the tar residue tank, the tar residue tank is arranged on a trolley, and the trolley is provided with a laser range finder. The system can overcome the defect that tar residue treatment is difficult to automatically operate in the prior art, effectively improves the operation environment of tar residue recovery treatment, and also has the advantages of convenience in automatic control operation, high adaptabilityand wide application prospect.

Description

technical field [0001] The invention relates to the technical field of automatic control of pollutant treatment in the coal coking production process, and more specifically relates to a fully sealed and environmentally friendly recycling control system for tar slag in the coal coking chemical industry. Background technique [0002] Tar residue is a viscous solid waste residue with coal tar adsorbed in the coal coking production process, which is mainly composed of polycyclic aromatic hydrocarbons, hydrocarbons, benzene, phenols, naphthalene, coal powder, coke powder, etc. Tar residue is corrosive and adhesive, and has a certain fluidity at a certain temperature. Improper storage will cause serious pollution to the surrounding environment and groundwater resources. In addition, the volatilization and escape of tar residues seriously polluted the surrounding air, affecting the physical and mental health of enterprise employees and surrounding people. Tar residues are hazardou...
