Problems solved by technology

[0006] The above countermeasures obviously have the following shortcomings: ①The waste gas is discharged directly without treatment; ②Although the cover is sealed, the waste gas is not sampled and analyzed and effectively treated, and the maintenance, repair and maintenance of the equipment and components in the unit structure are not given. Replacement, and observation of equipment operating conditions and other operations have brought difficulties; ③Although it has been covered and sealed, and exhaust pipes have been set up to discharge the exhaust gas at high altitudes, no sampling analysis and effective treatment have been done for the exhaust gas, and there are also exhaust gases in the unit structures. Difficult conditions such as maintenance, repair and replacement of equipment and components, and observation of equipment operating conditions

Embodiment 1

[0018] The surface aeration tank, the water treatment facility used for surface aeration reaction in the drainage workshop of petroleum refining enterprises, often emits waste gas containing hydrogen sulfide, benzene, and volatile hydrocarbons. By using the device of the invention, the surface aeration tank can be sealed to collect waste gas so as to facilitate sampling monitoring and purification treatment.

[0019] Such as figure 1 As shown, the middle part of the surface aeration tank 1 is the spiral mixer pump room 2, the outside of the 1 is the sedimentation area 3, and the ring area 4 between 1 and 3 is the surface aeration area, which is also the main area for generating exhaust gas. On the top of the aeration area 4, a top cover composed of standard sealing members 5 and 6 made of engineering plastics is arranged to seal the surface aeration area 4. A vent 7 is arranged on the member 5, and an exhaust pipe 8 is arranged on the member 6, which can be connected with fac...

Embodiment 2

[0027]The water treatment facility used for biochemical aeration reaction in the sewage treatment plant - blast aeration tank, often discharges waste gas containing hydrogen sulfide, benzene, volatile hydrocarbons and so on. The device of the invention is used to seal the aeration tank, collect waste gas and carry out purification treatment.

[0028] Such as Figure 7 As shown, in the aeration tank 17 is a blast aeration area 18, on the inner side wall of the aeration area 18, there is a chute 16; cover to seal the aeration area 18; components 19 and 20 are made of engineering plastics; a vent 21 equipped with a sealing cover is provided on component 19; an exhaust pipe 22 is provided on component 20, which can be discharged through joints and exhaust gas The pipeline is connected with facilities such as induced draft fan, gas purification treatment equipment or exhaust pipe.

[0029] The sealing components on the aeration area 18 are mainly composed of components 19, and on...

Abstract

The present invention relates to a kind of covered sealer, used especially in water processing facility to collect exhausted waste gas. By setting up a movable combined sealing top cover capable of being opened out and dranw in and easy to install and disassemble, the opened part of the structural unit in water processing facility may be sealed for waste gas collection, sampling and processing of waste gas or opened for service, overhaul and replacement of equipment and member inside the structural unit and observation of the equipoment running state.

Description

technical field [0001] The invention relates to a capped airtight device for industrial facilities, in particular to a capped airtight collection device for waste gas discharged from water treatment facilities. Background technique [0002] Various existing industrial wastewater and domestic sewage treatment facilities or devices (hereinafter collectively referred to as water treatment facilities) are usually composed of unit processes such as oil separation, neutralization, aeration, flotation, sedimentation, and their structures. Due to the effects of physical, chemical and biological factors, each unit process often produces some toxic and harmful substances, such as: volatile organic compounds (including low molecular alkanes, benzene series, phenolic compounds, etc.), sulfides (hydrogen sulfide , low molecular mercaptan, sulfide, dimethyl disulfide, etc.), ammonia, low molecular organic amine, etc. If these toxic and harmful substances are not treated effectively, they...
