Description
Technical Field
[0001] The utility model relates to the technical field of flue gas treatment production, in particular to a flue gas desulfurization, denitrification and dust removal device. Background Art
[0002] In recent years, due to the deterioration of the atmospheric environment, the emission standards of industrial furnace flue gas have become increasingly stringent. Some regions require that the environmental protection system must be used in a backup and ultra-low emission manner. Flue gas is a mixture of gas and smoke, and is the main cause of air pollution in residential areas. The composition of flue gas is very complex. The gas includes water vapor, sulfur dioxide, nitrogen, oxygen, carbon monoxide, carbon dioxide, hydrocarbons and nitrogen oxides, etc. The smoke includes fuel ash, coal particles, oil droplets and high-temperature cracking products. Therefore, it needs to be desulfurized, denitrified and dusted before it can be discharged;
[0003] The existing desulfurization, denitrification and dust removal equipment includes a treatment box. After the flue gas is introduced, the treatment agent is sprayed into the treatment box to allow the flue gas and the treatment agent to fully mix and react to achieve the effect of desulfurization and denitrification. The operation can be completed by filtering it. However, before the treatment, it is inevitable that there are a large number of particles such as dust in the flue gas. Directly using a spray pipe to spray it can easily cause the spray pipe to be blocked, thereby affecting the normal spraying of the treatment agent and affecting the dust removal efficiency. Therefore, a flue gas desulfurization, denitrification and dust removal device with a pre-treatment function and anti-clogging is required. Utility Model Content
[0004] The technical problem to be solved by the utility model is that a large amount of dust exists in the flue gas before it is treated, which easily leads to the blockage of the spray component and affects its use. Therefore, a flue gas desulfurization, denitrification and dust removal device with a pre-treatment function and anti-blocking is provided.
[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a flue gas desulfurization, denitrification and dust removal device, comprising a working box, a treatment agent box is fixedly provided on the left side of the top surface of the working box, a reaction box is provided in the center of the top surface of the working box, a spray cavity is provided in the reaction box, a plurality of sprayers connected with the treatment agent box are provided in the spray cavity, a pretreatment cavity is provided in the working box, a plurality of inclined dust removal nets are provided in the pretreatment cavity from left to right, an air inlet pipe connected with the pretreatment cavity is provided at the top left side of the working box, an air supply pipe connected with the pretreatment cavity and extending to the bottom end of the spray cavity is provided at the top of the right outer wall of the working box, and an exhaust pipe is provided on the right side of the reaction box.
[0006] As an improvement, a water pump connected to the spray cavity is provided at the top of the left outer wall of the reaction box body. The water inlet end of the water pump is connected to a water supply hose connected to the bottom end of the treatment agent box body. The other end of the water pump is connected to the sprayer to facilitate the spraying of the treatment agent.
[0007] As an improvement, the top of the reaction box is a conical structure, which facilitates full contact between the flue gas and the treatment agent.
[0008] As an improvement, a control panel is fixedly provided on the front outer wall of the reaction box, and the arrangement of the control panel is convenient for operators to operate.
[0009] As an improvement, the inclined dust removal net is arranged to be inclined from the upper left to the lower right, and multiple groups of the inclined dust removal nets are screwed together to perform sufficient dust removal pretreatment on the flue gas.
[0010] Compared with the prior art, the advantages of the utility model are: a pretreatment chamber is set up, and multiple inclined dust removal nets are set up in the pretreatment chamber. The flue gas is first introduced into the pretreatment chamber, and a large amount of dust and other impurities in the flue gas are filtered through the action of the multiple inclined dust removal nets. Then the flue gas enters the spray chamber for desulfurization, denitrification and dust removal treatment, thereby avoiding blockage of the spray component and ensuring work efficiency.
