Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention uses harmful gases discharged from small incinerators, etc. as a remover using granular alkali neutralizer, activated carbon adsorbent, etc., and removes harmful gases by utilizing its neutralizing action and adsorption action. It relates to a gas removal device.

[0002]

[Prior art]

 In the past, hazardous gas removal equipment was large and very expensive, and was not installed except for some large incinerators. Recently, the issue of hydrogen chloride and dioxin has been raised, and it has become urgent to install toxic gas removal equipment. However, there is almost no equipment for small incinerators, and the current situation is that pollution is pouring down.

[0003]

[Problems to be solved by the invention]

 The present invention aims to eliminate such inconvenience and develop a small and inexpensive harmful gas removal device.

[0004]

[Means for Solving the Problems]

 Now, let's explain the solution with reference to the drawings.

[A] In FIG. 2, a removing agent supply hopper 2 for containing and supplying the removing agent 3 is provided above the removing device main body 4.

[B] A shelf 5 for receiving the removing agent 3 is installed in an inverted C-shape or a U-shape inside the removing device body 4.

[C] A discharge valve 7 for discharging the used removing agent is provided at a lower portion of the removing device main body 4, and a collection box 9 for collecting the used removing agent is provided below the discharging valve 7.

[0005]

[Function] Since this model has the above structure, when using it, attach the harmful gas removal device through the flange 6 in the middle of the incinerator flue. The granular remover 3 is introduced into the remover supply hopper 2. Then, the removing agent 3 is piled up on the shelf 5 provided inside the removing device main body 4 and on the funnel portion of the removing device main body 4. When the harmful gas passes through this heaped portion, it reacts with the neutralizing agent and the adsorbent, and the harmful substances are neutralized, adsorbed and removed. The used remover is periodically discharged by the discharge valve 7 at regular intervals and collected in the lower collection box. Selection diagram

【Example】

 In the present invention, the following can be performed.

【I】

As shown in FIG. 3, the harmful gas removing device main body 4 is made larger, a plurality of sets of shelves 5 are provided in a square shape, and a lower portion of the harmful gas removing device body 4 is used to discharge and collect the used removing agent. By attaching the discharge screw conveyor 8 and the collection box 9, it is possible to deal with the exhaust gas from a larger incinerator.

[B]

As shown in FIG. 4, by installing and integrating a bag filter dust collector 10 in the removal device main body 4, the removal can be performed at a higher level.

[C] If gas is replaced with water, it can be used as a wastewater purification device.

[0007]

[Effect of the invention]

[B] The structure is small and simple, and there is no worry of failure.

[B] The discharge valve allows the used remover to be discharged periodically in a fixed amount, and is replaced with a new remover in conjunction with it.

[C] In order to cope with advanced processing, the contact time can be extended by providing the shelf 5 in a square shape.

[D] In order to cope with a larger throughput, it is easy to cope with the problem by simply making the harmful gas removing device main body 4 large and providing a plurality of sets of shelves 5.

[E] By installing and integrating the bag filter dust collector 10 in the harmful gas removal device main body 4, it is possible to remove the gas at a higher level.
