Problems solved by technology

Even so, the concentration of VOCs gas at a single printing machine or ink preparation equipment is still seriously exceeding the standard, and it is difficult to achieve a good purification effect for the entire workshop by relying on the existing air purification system alone

Embodiment Construction

[0011] Such as figure 1 shown. The device for removing VOCs gas in the printing workshop includes a driving car, a vehicle frame 13, a fan, a control dial and a car driving control box 7, and is characterized in that: the device also includes an adsorption purification device 5 arranged on the car, Suction cover 1 and air outlet pipe 11; Adsorption purification device 5 is cylindrical, also can be other shapes, is longitudinally installed on the chassis of vehicle frame 13, and its front end communicates with suction cover 1 through flexible air channel 3, flexible air duct 3 The channel 3 is arranged on the support arm 12 of the suction hood. The flexible air duct is made of fatigue-resistant PVC material and can be designed as an accordion bellows for easy expansion and contraction. The support arm 12 of the suction hood is connected with the inner frame of the suction hood through the first movable joint 4 and the second movable joint 14 successively, so that the suction ...

Abstract

The invention discloses a device for movably eliminating VOCs gas in a printing workshop. The device comprises an adsorption cleaning device (5) arranged on a trolley, a suction guard (1) and an air duct (11); the adsorption cleaning device (5) is longitudinally installed on a chassis of a frame (13), the front end of the adsorption cleaning device (5) is communicated with the suction guard (1) through a flexible air flue (3), the flexible air flue (3) is arranged on a suction guard support arm (12), the suction guard support arm (12) is connected an inside frame of the suction guard through a first movable joint (4) and a second movable joint (14) in order, so that the suction guard (1) is capable of freely rotating under the support of the suction guard support arm power and a transmission case (6). The device can be used for flexibly and freely eliminating harmful waste gas at high-concentration VOCs gas production equipment in the printing workshop, the concentration of the VOCs gas directly discharged into the air flue or the atmosphere is reduced, so that the whole VOCs gas concentration in the workshop can be effectively reduced, and the good energy-saving and emission-reduction effect can be realized.

Description

technical field [0001] The invention relates to a device for removing harmful industrial waste gas, in particular to a device for removing VOCs gas in a mobile printing workshop in the printing and packaging industry. Background technique [0002] Volatile organic compounds (VOCs for short) refer to all organic compounds whose vapor pressure is greater than or equal to 0.01kPa at 20°C, or which have corresponding volatility under specific applicable conditions. VOCs are important precursors of near-surface ozone (O3), which have serious adverse effects on urban haze and photochemical pollution. With the continuous and stable development of the national economy and the rapid development of the upstream ink industry of the printing and packaging industry, the printing and reproduction industry has developed rapidly in recent years and has become the pillar of the cultural industry. The main pollutants emitted by the printing industry are organic waste gases containing VOCs. T...
