Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a dehumidification device for dust collectors. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device. It is suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle down due to gravity and fall into the ash hopper. The gas containing finer dust particles is purified as it passes through the filter media, with the dust being trapped.

[0003] When the humidity of the air entering the bag filter is high, a water film may form on the surface of the filter bag, making it easier for dust particles to adhere to the filter bag and increasing the risk of clogging. Moisture may also affect the properties of the dust, making it heavier or stickier, resulting in reduced dust removal efficiency and inability to effectively remove dust from the air. Utility Model Content

[0004] The purpose of this invention is to provide a dehumidification device for a dust collector, which has the effect of dehumidifying the gas entering the dust collector and maintaining the normal operation of the dust collector.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a dehumidification device for a dust collector, comprising a dehumidification box, an inlet pipe and an outlet pipe installed on both sides of the dehumidification box, wherein a dehumidification component and a drying component are sequentially arranged in the dehumidification box along the direction from the inlet pipe to the outlet pipe, the dehumidification component comprising multiple layers of dehumidification plates fixed in the dehumidification box, the dehumidification plates being provided with ventilation holes, and the drying component comprising multiple layers of drying cylinders concentrically arranged fixed in the dehumidification box, wherein an electric heating wire is fixed inside the drying cylinder.

[0006] By adopting the above technical solution, the dehumidification box is installed at the front end of the dust collector, and the air outlet pipe is connected to the air inlet of the dust collector. The suction force of the dust collector draws air in from the air inlet pipe. After passing through the dehumidification component and the drying component, the air enters the dust collector from the air outlet pipe. The dehumidification plate is made of moisture-absorbing material, which initially dehumidifies the air entering the dehumidification box. The multi-layer dehumidification plate enhances the dehumidification effect. The heating wire in the drying component further heats and dries the air passing through the drying cylinder. The multi-layer drying cylinder increases the contact area with the air, thereby improving the dehumidification efficiency and controlling the humidity in the air.

[0007] A further feature of this invention is that the dehumidification plate has multiple protrusions.

[0008] By adopting the above technical solution, the multiple protrusions help to increase the contact area between the moisture-absorbing material and the air, thereby improving the dehumidification efficiency.

[0009] A further feature of this invention is that the multi-layer drying cylinder has a cavity, and the heating wire is disposed within the cavity.

[0010] By adopting the above technical solution, the heating wire is enclosed in the cavity, which can reduce heat loss, thereby improving heating efficiency and saving energy costs.

[0011] A further feature of this invention is that a cross support frame is fixed inside the dehumidification box, located on both sides of the multi-layer drying cylinder. The cross support frame is provided with a slot, and both sides of the drying cylinder are respectively engaged in the slots of the cross support frame on both sides.

[0012] By adopting the above technical solution, multiple drying cylinders can be set at intervals, thereby fully drying the passing air.

[0013] A further feature of this invention is that a separation component is provided inside the dehumidification box, the separation component separates the dry gas and water vapor, and the outlet pipe is located between the drying component and the separation component.

[0014] By adopting the above technical solution, the separation component separates the dry gas from the water vapor in the gas, further reducing the air humidity and thus avoiding affecting the performance of the bag filter.

[0015] A further feature of this invention is that the separation assembly includes a water vapor separation membrane fixed inside the dehumidification chamber, a guide plate fixed inside the dehumidification chamber on the side of the water vapor separation membrane away from the drying cylinder, and a condenser tube disposed inside the guide plate.

[0016] By adopting the above technical solution, after the air is dried by passing through the drying cylinder, the water vapor in the air passes through the water vapor separation membrane, and the dried air enters the bag filter through the air outlet pipe. The water vapor passing through the water vapor separation membrane is condensed into water droplets by the condenser tube and falls off the guide plate.

[0017] A further feature of this invention is that the guide plate is inclined, and the dehumidification box is connected to a water outlet pipe located below the guide plate.

[0018] By adopting the above technical solution, the water vapor condensed into water droplets falls out of the water outlet pipe under the action of the guide plate, realizing the separation of dry gas and water vapor and improving the air dehumidification efficiency.

[0019] A further feature of this invention is that the dehumidification box is provided with an inspection port, and the dehumidification box is hinged with a cover plate that covers the inspection port.

[0020] By adopting the above technical solution, the internal components of the dehumidifier can be inspected through the inspection port after opening the cover, which is beneficial for later maintenance.

[0021] A further feature of this invention is that the cover plate is threadedly connected with mounting bolts that extend into the dehumidification box.

[0022] By adopting the above technical solution, the cover plate can be fixed by the mounting bolts or the mounting bolts can be removed so that the cover plate can rotate relative to the dehumidification box to open the maintenance port.

[0023] A further feature of this invention is that: the inner wall of the dehumidification box is provided with limiting grooves on both sides, and the dehumidification plate is engaged with the limiting grooves on both sides.

[0024] By adopting the above technical solution, the dehumidifier plate can be pulled out and replaced from the dehumidifier box after opening the inspection port.

[0025] The beneficial effects of this utility model are:

[0026] 1. After passing through the inlet pipe, the air passes through the dehumidification and drying components and then enters the dust collector through the outlet pipe. The dehumidification plate is made of moisture-absorbing material and performs initial dehumidification on the air entering the dehumidification chamber. Multiple layers of dehumidification plates enhance the dehumidification effect. The heating wire in the drying component further heats and dries the air passing through the drying cylinder. The multiple layers of the drying cylinder increase the contact area with the air, thereby improving the dehumidification efficiency and controlling the humidity in the air.

[0027] 2. After the air is dried in the drying cylinder, the water vapor in the air passes through the water vapor separation membrane, while the dried air enters the bag filter through the outlet pipe. The water vapor that passes through the water vapor separation membrane is condensed into water droplets by the condenser tube and falls off the guide plate, thus achieving the separation of dry gas and water vapor and improving the air dehumidification efficiency.
