Description
Technical Field
The utility model belongs to the technical field of the environmental protection and specifically relates to an environmental protection is harmful gas processing apparatus for engineering.
Background
Common toxic and harmful gases are classified into: irritant gases are gases which have an irritating effect on the mucous membranes of the eye and respiratory tract and are toxic gases which are frequently encountered in the chemical industry. The types of irritant gases are various, the most common gases are chlorine, ammonia, nitrogen oxide, phosgene, hydrogen fluoride, sulfur dioxide, sulfur trioxide, dimethyl sulfate and the like, and the asphyxiant gases refer to toxic gases which can cause oxygen deficiency of organisms and can be divided into pure asphyxia gases, blood asphyxia gases and cell asphyxia gases. Such as nitrogen, methane, ethane, ethylene, carbon monoxide, nitrobenzene vapor, hydrogen cyanide, hydrogen sulfide, etc., and irritant gases exist in many industrial processes, such as electric welding, electroplating, smelting, chemical industry, petroleum, etc. These gases are corrosive and enter the human body through the respiratory tract, which can cause acute poisoning. The common characteristic of toxic action of irritant gases on the body is that they have different degrees of irritation to the eyes, respiratory mucosa and skin. Local lesions are usually the major cause, but systemic reactions can also be induced. The 'triacid' steam can stimulate respiratory tract mucosa, can also cause skin burn, can stimulate teeth after being contacted with low-concentration acid mist for a long time, can cause tooth erosion, has high water solubility of chlorine, ammonia, sulfur dioxide, sulfur trioxide and the like, and can easily cause damage when meeting wet parts. After the gas is inhaled, the upper respiratory tract mucosa is dissolved to directly stimulate the mucosa, so that the congestion, the edema and the secretion of the upper respiratory tract mucosa are increased, a chemical inflammatory reaction is generated, symptoms such as running nose, throat itching, choking cough and the like are presented, the water solubility of nitric oxide, phosgene and the like is low, and the hydrolysis effect is rarely caused when the nitric oxide, the phosgene and the like pass through the upper respiratory tract mucosa, so the irritation effect of the mucosa is slight; but can go on going deep into bronchus and alveolus, act with the moisture on the mucosa gradually, produce stronger stimulation and corrosive action to the lung tissue, pulmonary edema appears in serious cases, the prevention of irritant gas is key, stop accident, prevent running, overflowing, dripping, leaking, and do waste gas recovery and comprehensive utilization well, the automation, mechanization and pipelining of the production process adopts the automatic control technology, the automatic adjustment maintains the normal operating condition, prevent the accident from happening; the airtightness of the equipment is improved, and the corrosion and the breakage of the metal equipment are prevented; according to the characteristics of production process, a proper ventilation method is selected to enhance personal protection, and when a large amount of corrosive liquid poisons such as acid, alkali and the like are contacted, corrosion-resistant protective tools such as polyvinyl chloride, rubber products, rubber gloves, protective glasses, protective rubber shoes and the like are worn, a gas mask or a protective mask is worn, and skin protective ointment is coated. Strengthening health care, and carrying out pre-post and regular physical examination to find allergic asthma, allergic dermatoses or eczema at exposed parts of skin, chronic respiratory diseases such as eyes, nose, throat and trachea, pulmonary tuberculosis (including stable phase) and heart disease, which should not be contacted with irritant gas.
Traditional tail gas processing apparatus, generally adopt the method of chemical reaction during the processing, a large amount of resources can be wasted to this kind of mode, and the effect of handling is not good, after adsorbing harmful gas with active carbon, active carbon is difficult to change, and active carbon can not used repeatedly, some contain a large amount of vapor and dust in the gas, these substances can influence subsequent harmful gas and handle when not handling at the beginning, many gases also are very important resources after the conversion in addition, these gases can pollute the environment in discharging the air, harm human health, for example carbon monoxide can use as water gas after the reaction, but traditional processing mode is directly absorbing or burning, not only not environmental protection also can cause very big waste of resources, the investment cost has been increaseed, in order to solve above-mentioned problem, we have proposed this kind of harmful gas processing apparatus for environmental protection engineering.
