Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a dust removing gas purifier that removes fine substances floating in an atmosphere, for example, liquids such as oil and water, dusts of scales and various mineral substances, and smoke-like substances.

[0002]

[Prior art]

 Conventionally, dust removers and dust collectors are mainly composed of multi-stage filter units that combine filters with different eyes, or those that combine a filter unit with a cyclone-type dust collector or an electric dust collector. For example, a looper-type dust collector disclosed in Japanese Utility Model Laid-Open No. 57-187620, for example, has a shower provided between a plurality of filter units or a device provided with a filler layer having a predetermined thickness. It is proposed in Japanese Patent Laid-Open No. 62-38218.

[0003]

[Problems to be solved by the invention]

 However, conventional dust removal equipment requires large-sized equipment to increase the dust removal efficiency if the collected material is fine, or if the gas contains small droplets of small mass such as oil or moisture. It requires expensive processing equipment and has low investment efficiency.

[0004] An object of the present invention is to provide a dust-removing gas purifier capable of reducing the size of equipment and having a high dust-removing effect even for suspended substances in which various fine substances are mixed.

[0005]

[Means for Solving the Problems]

 The present invention relates to a dust removing device mainly configured of a filter unit or a plurality of filter units for collecting suspended substances, which is used in combination with a gas inlet section containing suspended fine substances in front of the dust removing apparatus. An apparatus for separating suspended fine substances, wherein the separation apparatus has a support having a plate-like body or a net-like body having a large number of gas passage holes, which blocks the flow of gas and traps the suspended fine substances. A baffle plate with a plate-like body to be collected is installed.Further, a filter unit or an assembled filter unit is installed next to the baffle plate, and a desired preparation liquid is supplied to the gas inlet surface in the gas flow direction. This is a dust removing gas purifier characterized by connecting one or more stages of a suspended fine substance separation device provided with a spray nozzle for spraying.

Further, the present invention provides the above dust removing gas purifier, wherein the baffle plate on which the plate-like body for collecting suspended fine substances is attached is a baffle plate with a large number of narrow plate-like bodies attached thereto, and a corrugated plate-like body. Alternatively, the present invention is a dust-removing gas purifier characterized by installing a baffle plate to which a plate-like body having a large number of irregularities is attached, or a baffle plate to which a plate-like body in which these are mixed is attached.

[0007] Further, the present invention provides the dust removing gas purifier, wherein the mounting angle of the plate for collecting the suspended fine substance is set in a range of 20 to 65 degrees with respect to the support. It is a dust purifier characterized by the following.

[0008] In addition, the present invention provides a dust collecting gas purifier as described above, wherein a solution collecting section for circulating and using a spray solution of a suspended fine substance separation device, separates and removes collected fine substances from a recovered liquid to regenerate the solution. This is a dust removing gas purifier characterized by including a solution regenerating section, a spray solution storing section, and a circulation pump.

Further, the present invention provides the dust removing gas purifier, wherein a filter cleaning liquid spray nozzle is provided on the surface of the filter unit or the filter unit of the apparatus for separating suspended fine substances. is there.

[0010] That is, the gas suspended fine substance separation device of the present invention includes a gas inlet and a front part of a dust remover (hereinafter, simply referred to as a dust remover) configured to collect suspended fine substances mainly composed of a conventional filter. This is either a direct-coupled device that is directly attached to the section and configured as a single unit, or a dust-type gas purifier that is a separate-type device that is configured by connecting the front part of a dust-removing device and a device for separating suspended fine substances with a duct.

In addition, since the mounting angle of the plate-like body for collecting suspended fine substances of the present invention affects the collection effect, the physical properties such as the shape, mass, and cohesiveness of the collected suspended fine substances are affected. Although it is determined in consideration of the quality, usually, a suitable baffle plate can be obtained by setting it at a range of 20 to 65 degrees with respect to the support. If the angle is out of the range, the trapping effect may be reduced, and the flow resistance of the gas may be increased to increase the equipment cost, which is not preferable.

Next, a baffle plate to which the suspended fine substance trapping plate is attached is placed in the gas flow. The number and shape of the baffles are determined by considering mainly the physical properties of the suspended microscopic substances to be collected, the flow velocity of the gas passing through the baffle, and the shape and size of the plate attached to the baffle. However, usually, one to ten baffle plates may be provided.

[0013] Further, the dust-removing gas purifier of the present invention uses a spray liquid prepared in a desired state in consideration of the properties of the fine substance to be collected. A solution spray nozzle is provided at a position where the solution is sprayed in the gas flow direction. In addition, a spray nozzle for spraying a cleaning liquid for cleaning the filter unit or the filter unit installed following the baffle plate may be provided and used as needed.

In addition, since it is environmentally preferable that the sprayed solution is circulated and used environmentally, a solution collection unit, a solution regeneration unit that separates and removes collected fine substances from the recovered liquid to regenerate the solution, a storage unit for the spray solution, In addition, it is preferable to provide a solution circulation and use equipment provided with a circulation pump for circulating the solution.

Further, a feature of the dust removal gas purifier of the present invention is that a solution is sprayed in a gas flow direction on a baffle plate surface of a gas inlet of a suspended fine substance separation device or a filter surface provided in front of a baffle plate. An object of the present invention is to provide a spray nozzle at a position and spray a desired solution so that suspended fine substances are easily collected by a baffle plate to enhance a dust removing effect.

[0016]

[Action] The dust-removing gas purifier of the present invention installs a baffle plate with a collecting plate in a gas flow containing suspended fine substances, and sprays the prepared solution in the direction of gas flow to float. The fine substance can be sufficiently wetted, the mass of the suspended fine substance can be increased, and the trapping effect on the baffle plate can be enhanced.
