Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dust collectors, and particularly relates to a desulfurization and denitrification dust collector. Background Art
[0002] The desulfurization and denitrification dust collector is a commonly used device in the environmental protection field, and is mainly used for removing harmful substances such as sulfur oxides (such as sulfur dioxide SO2), nitrogen oxides (such as nitric oxide NO and nitrogen dioxide NO2), and particulate matter in industrial emissions such as coal combustion and fuel oil.
[0003] In the traditional dust collector, there may be a problem that the flue gas cannot be in full contact with the filter layer. If the flue gas cannot be in full contact with the filter layer, a large amount of particulate matter will directly pass through the filter layer without being trapped, resulting in a significant decrease in the dust removal efficiency, a decrease in the capture efficiency of the adsorbent, and a reduction in the desulfurization and denitrification effect. Due to the decrease in the dust removal efficiency, the emission concentration of particulate matter in the flue gas will increase significantly, probably exceeding the emission standards specified by environmental protection regulations, thus causing environmental pollution problems.
[0004] Therefore, it is necessary to invent a desulfurization and denitrification dust collector to solve the above problems. Content of the Utility Model
[0005] To solve the deficiencies of the prior art, the purpose of the utility model is to provide a desulfurization and denitrification dust collector, which solves the problem that the flue gas may not be in full contact with the filter layer during actual use. If the flue gas cannot be in full contact with the filter layer, a large amount of particulate matter will directly pass through the filter layer without being trapped, resulting in a significant decrease in the dust removal efficiency, a decrease in the capture efficiency of the adsorbent, and a reduction in the desulfurization and denitrification effect.
[0006] To achieve the above goal, the utility model adopts the following technical solutions:
[0007] A desulfurization and denitrification dust collector includes a housing. Side covers are detachably installed on both side walls of the housing.

An adsorbent for adsorbing and purifying sulfides and nitrate compounds is loaded inside the filter cavities.

[0008] As a preferred solution of the utility model, the overall shape of the filter cavity is L-shaped. The short side of the filter cavity is arranged longitudinally, and the long side of the filter cavity is arranged horizontally. The short side of the filter cavity at the bottom end of the housing is detachably connected to the intake pipe, and the long side of the filter cavity at the top end of the housing is detachably connected to the outlet pipe.
[0009] As a preferred embodiment of the present utility model, a plurality of filter holes for allowing waste gas to pass through and for carrying and preventing the adsorbent from falling off are provided at the bottom end of the short side of the filter cavity. A feeding chute is provided on one side of the horizontal side of the filter cavity. The combined arrangement of a plurality of the filter cavities forms a flue gas passage with multiple turns.

The limiting baffles are respectively located on both sides of the filter cavity. A pressing push plate located inside the housing is slidably arranged on the outer side of the limiting baffle. A plurality of adjusting bolts for adjusting the relative position of the pressing push plate are threadedly connected to the outer surface of the housing.

[0013] As a preferred embodiment of the present utility model, the adsorbent loaded inside the filter cavity is activated carbon.
[0014] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:
[0015] In the present utility model, by assembling a plurality of filter cavities into a flue gas passage with multiple bends, during the transportation of the flue gas of sulfides and nitro compounds from the intake pipe to the outlet pipe, the contact time between the flue gas and the activated carbon is prolonged, and the flue gas is in full contact with the gas, thereby significantly improving the adsorption and purification effect.

[0021] The present utility model will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.
[0022] The present utility model provides a desulfurization and denitrification dust collector as Figures 1-4 shown, including a housing 1. Side covers 2 are detachably installed on both side walls of the housing 1. An intake duct 4 is connected to one side of the side cover 2. An exhaust duct 5 is connected to the top end of the housing 1. A plurality of filter cavities 9 are detachably installed inside the housing 1. An adsorbent for adsorbing and purifying sulfides and nitrate compounds is loaded inside the filter cavity 9. A plurality of cooling chambers 8 for improving the adsorption effect by cooling are also provided inside the housing 1. By disassembling the side covers 2 on both sides, the product can be quickly assembled, reducing the installation difficulty of the device. A sealing rubber strip is provided on the contact surface between the side cover 2 and the housing 1 to prevent flue gas leakage. The side cover 2 can be provided with a plurality of interfaces for electrically connecting the refrigeration machine 10 and exhaust holes for heat dissipation.
[0023] The overall shape of the filter cavity 9 is L-shaped. The short side of the filter cavity 9 is arranged longitudinally, and the long side of the filter cavity 9 is arranged horizontally. The short side of the filter cavity 9 located at the bottom end of the housing 1 is detachably connected to the intake duct 4. The long side of the filter cavity 9 located at the top end of the housing 1 is detachably connected to the exhaust duct 5. The exhaust duct 5 is fixedly installed inside the housing 1, and its bottom end is adapted to the slide rail 13 at the top end of the filter cavity 9 to ensure the reliability of the connection, prevent the leakage of flue gas, and ensure the dust removal effect.
[0024] A plurality of filter holes 11 for allowing waste gas to pass through and for carrying and preventing the adsorbent from falling off are opened at the bottom end of the short side of the filter cavity 9. A blanking chute 14 is opened on one side of the horizontal side of the filter cavity 9. The combined arrangement of a plurality of filter cavities 9 forms a flue gas passage with multiple turns, increasing the contact area between the flue gas and the adsorbent during the flow process, thereby improving the adsorption efficiency.
[0025] A plurality of limiting baffles 15 are installed at the top and bottom of the housing 1. The limiting baffles 15 are respectively located on both sides of the filtering cavity 9. A squeezing push plate 6 located inside the housing 1 is slidably arranged on the outer side of the limiting baffle 15. A plurality of adjusting bolts 3 for adjusting the relative position of the squeezing push plate 6 are threadedly connected to the outer surface of the housing 1. A plurality of guiding blocks 7 facilitating installation are detachably installed on the inner side wall of the limiting baffle 15. The adjustable setting of the squeezing push plate 6 can reduce the clearance inside the device, fix the filtering cavity 9, and prevent the sealing effect from failing due to factors such as vibration.
[0026] At one side of the top end of the filtering cavity 9 and located at the lower side of the feeding chute 14, a limiting step 12 adapted to the bottom dimension of the transverse side of the filtering cavity 9 is provided. Slide rails 13 for the installation and splicing of the filtering cavity 9 are provided on both sides of the feeding chute 14. The setting of the limiting step 12 and the slide rails 13 facilitates the docking of the filtering cavity 9, and can also intercept through the limiting step 12 to make it move to the specified position with accurate positioning, thereby avoiding the generation of large gaps and affecting the adsorption effect.
[0027] A refrigerating machine 10 is electrically connected inside the cooling chamber 8. The cooling chamber 8 can fill the space inside the housing 1. The end face of the cooling chamber 8 abuts against the short side of the filtering cavity 9, providing effective support for the filtering cavity 9, improving the reliability of the connection relationship, and preventing the components from separating inside the housing 1.
[0028] The adsorbent loaded inside the filtering cavity 9 is activated carbon. The adsorbent adopts activated carbon particles, which not only meets the requirements of desulfurization and denitrification, but also facilitates the timely replacement of the filtering cavity 9, and can also prevent the activated carbon particles from falling off along the filtering holes 11, reducing the maintenance cost of the product.
[0029] In this utility model, by assembling a plurality of filtering cavities 9 into a flue gas passage with multiple bends, during the transportation of the flue gas containing sulfides and nitrogen compounds from the intake pipe 4 to the outlet pipe 5, the contact time between the flue gas and the activated carbon is prolonged, enabling the flue gas to fully contact with the gas, thereby significantly improving the adsorption and purification effect. In the gap of the filtering cavity 9, the provided cooling chamber 8 can effectively reduce the temperature of the gas. When the temperature decreases, the thermal motion of molecules slows down, which is conducive to the flue gas being captured and fixed on the surface of the activated carbon, thereby improving the desulfurization and denitrification effect. The detachable structural design of the filtering cavity 9 facilitates the timely replacement and cleaning of the filter element, reducing the maintenance difficulty of the product.
[0030] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
