Abstract
A boiler exhaust gas desulfurization device includes an desulfurization tower, a spray device, an oxygen feeding device, a first pool and a second pool, and is characterized in that the left side of the desulfurization tower is connected with a gas inlet pipe, the top of the desulfurization tower is equipped with the spray device, the oxygen feeding device is arranged near the spray device, an oxygen feeding port is arranged below the oxygen feeding device, the middle of the desulfurization tower is equipped with a separation layer, the upper side of the separation layer is equipped with the first pool, and the first pool is located just below the spray device; the separation layer is equipped with a small hole, the lower side of the small hole is connected with a communication pipe, the communication pipe is inserted into the bottom of the second pool, and the second pool is located at the bottom of the desulfurization tower; and the upper side of the second pool is equipped with a gas outlet pipe. The boiler exhaust gas desulfurization device has the advantages that sulfurous gas generated by a boiler can be removed for twice, environmental pollution caused by incomplete one-time removal is avoided, at the same time, by-products can also be prepared through first-time sulfur removal, the environment is protected, benefits are increased, and production manufacturing is facilitated.
Description
Technical field
the invention belongs to mechanical engineering field, especially relate to a kind of boiler waste gas desulphurization plant.
Background technology
industrial waste gas refers to the various general names containing contaminant gases entering air produced in enterprise's on-site fuel combustion and production process, these waste gas have: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxide, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist) plumbous mercury, beryllide, flue dust and industrial dust, enter air, can contaminated air.These materials enter in the body of people by different approach respiratory tracts, and the direct generation harm had, what have also has cumulative effect, the health of harm people that can be more serious.
industrial waste gas can increase annual precipitation: the particulate ejected from large industrial city, wherein has the effect much with condensation of moisture core.Therefore, in time having some other precipitation condition to coordinate with it in air, just there will be precipitation weather.Leeward area in large industrial city, precipitation is more; Lower acid rain: sometimes, containing sulfuric acid from the rainwater that sky falls.This acid rain is that the pollutant sulfur dioxide in air forms sulfuric acid through peroxidating, falls to being formed with natural precipitation.Sulfuric acid rain can make large stretches of forests and crops damage, and the corrosion such as paper product, textile, leather and fur products can be made broken, the antirusting paint of metal can be made rotten and reduce protective effect, also can pollute building by burn into.
therefore, the sulphur of dispelling in industrial waste gas is the important composition of exhaust-gas treatment, by introducing the analysis and research of sulfur removal technology pilot factory situation condition to domestic and international desulfur technology and domestic electrical industry, current sulfur method generally can be divided into the front desulfurization of burning, 3 classes such as desulfurization and the rear desulfurization of burning in burning, wherein desulfurization after burning, also known as flue gas desulfurization, comprise and can be divided into following Lung biopsy: by CaCO3(lime stone) based on calcium method, magnesium processes based on MgO, sodium method based on Na2SO3, ammonia process based on NH3, organic alkaline process based on organic base.But any one method is used alone all can have part sulphur gas to be separated, and still can cause atmosphere pollution.
Summary of the invention
the object of this invention is to provide a kind of sulphur-containing substance effectively can removed boiler waste gas and discharge, reach the object purified air.
Summary of the invention
the object of the present invention is achieved like this, a kind of boiler waste gas desulphurization plant, comprise desulfurizing tower, sprinkling equipment, beat oxygen equipment, the first pond and the second pond, connect air inlet pipe on the left of described desulfurizing tower, desulfurizing tower top is provided with sprinkling equipment, and other being provided with of sprinkling equipment beats oxygen equipment, beat below oxygen equipment and be provided with dozen oxygen mouth, be provided with insulating course in the middle part of described desulfurizing tower, insulating course top is provided with the first pond, and the first described pond is positioned at immediately below sprinkling equipment; Described insulating course is provided with aperture, connects pipe below aperture, is inserted into the bottom in the second pond described communicating pipe, and the second described pond is positioned at the bottom of desulfurizing tower; Escape pipe is provided with above the second described pond.
ammonia alkali solution is provided with in described sprinkling equipment,
the first described pond is built with alkaline solution.
the second described pond adds water built with agstone and makes slurries.
the invention has the advantages that: twice removing can be carried out to the sulfurous gas that boiler produces; avoid and once remove the not thoroughly environmental pollution caused, byproduct can also be obtained by first time sulphur removal simultaneously, both protect environment; turn increase benefit, be of value to the manufacturing.
