A set of heater is arranged in the tank body, and the temperature controller is used for controlling heating temperature. The whole device has simple structure and low cost, is easy and convenient to operate, and is beneficial to industrial production and environment protection.

Description

A kind of absorption plant of organic exhaust gas

Technical field

The utility model relates to exhaust gas absorption device, particularly at a kind of absorption plant of volatile organic waste gas.

Background technology

Organic exhaust gas has toxicity, mainly be present in organic synthesis, synthetic rubber, paint and the processes such as dyestuff, PETROLEUM PROCESSING, having a strong impact on human health, thus must efficiently handle it, and processing method mainly comprises physical absorption, chemical absorbing and biological treatment.Physical absorption is primarily aimed at low concentration, high-throughout processing; The biological treatment cycle is long, is not suitable for industrial production; Chemical absorbing is applicable to that various operating modes, maintenance cost are low.

This processing method is selected absorption process for use, and the design by to absorbent screening and absorptive unit proposes a kind of absorption plant, when improving assimilation effect, simplifies the operation, and is beneficial to production.In absorption process, this method be with liquid flux as absorbent, the harmful components in the waste gas are absorbed by liquid, and tail gas are monitored, thereby reach the purpose of safety dumping.

The utility model content

Technical problem to be solved in the utility model is the absorption plant of a kind of waste gas that the pollution concentration and the treatment effeciency of whole absorption process are monitored in real time of design.

In order to address the above problem, the utility model is taked following technical scheme:

A kind of absorption plant of organic exhaust gas comprises waste gas gas handling system, absorption system and monitoring system three parts.The absorptive unit at core place comprises, casing, absorption tower, heater, booster pump, fluid flowmeter and liquid distribution trough; And gas handling system comprises air compressor, gas flowmeter and gas mixer, and monitoring system comprises detector.According to the detection data of monitoring system to exhaust emissions concentration, factors such as the tolerance by adjusting gas handling system, the spray flux of absorption system, temperature, liquid-gas ratio make concentration of emission up to standard.

The beneficial effects of the utility model are: the utility model has been installed detector at the absorption system end, can monitor constantly absorption process, at any time absorption factor is made suitable adjustment.Package unit is simple in structure, expense is cheap, easy and simple to handle, be beneficial to industrial production and environmental protection work.

Description of drawings

Fig. 1 is the process chart of organic exhaust gas absorption plant among the embodiment.

Number in the figure is: the 1-air compressor; 2-gas flowmeter one; The 3-gas mixer; 4-gas flowmeter two; 5-detector one; 6-gas flowmeter three; 7-detector two; The 8-liquid distribution trough; The 9-absorption tower; The 10-fluid flowmeter; The 11-elevator pump; The 12-casing; The 13-heater; The 14-temperature controller.

The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to Fig. 1, a kind of absorption plant of organic exhaust gas comprises compositions such as air compressor, gas mixer, gas flowmeter one, gas flowmeter two, gas flowmeter three, detector one, detector two, casing, absorption tower, liquid distribution trough, elevator pump, fluid flowmeter, heater and temperature controller.Its concrete ruuning situation is: provide the clean gas and the pollution waste gas at A place, workshop exhaust passage to be mixed in gas mixer by air compressor, its mixed proportion is by gas flowmeter one, gas flowmeter two controls, purpose is that waste gas is evenly distributed in order to make, pollution concentration is moderate, is beneficial to the absorption in later stage; Gas enters the absorption tower after mixing, and is provided with detector one at the absorption tower air inlet, can measure exhaust gas inlet concentration, under different working conditions, and the inlet gas concentration difference, this can regulate by gas flowmeter three; Absorbents such as waste lubricating oil are housed in the casing, absorbent are imported in the absorption tower by the effect of elevator pump, even for treatment effect, be provided with liquid distribution trough, outlet is provided with detector two on the absorption tower, monitors waste gas outlet concentration constantly; Under special operation condition, the temperature of absorbent so be provided with a cover heater in casing, is controlled heating-up temperature by temperature controller to the very big influence that is absorbed with of waste gas.Its objective is: by the detection constantly of detector, in time each pipeline flow is regulated and control, made whole waste gas absorption process more efficient; The factor that influences absorption efficiency is done comprehensive analysis, increase the regulator control system of some key factors,, can in factory, be extensive use of at comparatively complicated operating mode such as heater.

In the making of actual sample, the spy has adopted following measures to optimize this device:

The absorption tower accounts for very large space, and the absorbent use amount is also very big, so the spy installs the absorption tower on the casing of dress absorbent, elevator pump is installed on the casing, has saved the space greatly, has solved the contradiction between equipment occupation of land and the factory's area; Also reduce the laying of pipeline simultaneously, saved mounting cost.

In exhaust gas inlet and outlet air monitor is set respectively, can monitors constantly, for the regulation and control of factors such as gas flow, fluid flow, temperature, pressure provide information timely and effectively exhaust gas concentration; Simultaneously, reduced when personnel take a sample the time of contact poisonous fume, guaranteed that personnel's is healthy.

Characteristics of the present utility model are, dusty gas is carried out on-line monitoring, according to Monitoring Data each link are regulated and control, and have improved absorption efficiency; Complete equipment is simple to operate, quick, the handling rate height, and maintenance cost is cheap, is fit to produce use.

The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
