Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitators and electrostatic dust removal technology, and in particular to an explosion-proof insulating box structure for an electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator is an industrial device that uses a high-voltage electric field to charge impurities such as dust, tar, and water mist in coal gas, and then separates them under the influence of the electric field to collect these impurities. Its working principle is as follows: a negative high voltage generated by a high-voltage DC power supply is connected to the corona electrode through an insulating box. A strong electric field is generated between the corona electrode and the precipitating electrode due to the high voltage. Tar, dust, and other particulate matter in the coal gas become charged in the strong electric field. Under the influence of the electric field force, the charged particles move towards the precipitating electrode. Upon reaching the precipitating electrode, since the precipitating electrode is the anode, the negatively charged particles undergo a neutralization reaction with the positively charged precipitating electrode. The neutralized particles are first adsorbed onto the precipitating electrode and then fall down the electrode plates due to their own gravity. Thus, the tar, dust, and other particulate matter in the coal gas are separated from the coal gas.

[0003] Existing electrostatic precipitators (such as the one disclosed in application number 201610097461.4) include a cylinder, multiple insulating boxes, multiple insulators, multiple upper connecting rods, multiple lower connecting rods, an upper hanger, and multiple corona electrodes. The top of the cylinder has multiple mounting openings, and the bottom of each insulating box is open. The openings at the bottom of each insulating box correspond one-to-one with the mounting openings and are connected via flanges. The insulators are fixedly covered by the upper connecting rods, forming a single unit. Each insulator and each upper connecting rod is internally fitted into its respective mounting box. Inside the insulation box, each insulator is detachably and fixedly connected to each insulation box. The lower end of each lower connecting rod is built into the cylinder, and the upper end of each lower connecting rod passes through each mounting port and extends into the corresponding insulation box. The upper end of each lower connecting rod is detachably and fixedly connected to the lower end of each upper connecting rod. The upper hanger is built into the cylinder, and the upper hanger is detachably and fixedly connected to the lower end of each lower connecting rod. Each corona electrode is built into the cylinder, and the upper end of each corona electrode is detachably and fixedly connected to the upper hanger. In the above-described electrostatic precipitator, each upper connecting rod, each lower connecting rod, the upper hanger, and each corona electrode are made of conductive material. After the negative terminal of the power supply system is electrically connected to each upper connecting rod, each upper connecting rod, each lower connecting rod, the upper hanger, and each corona electrode can form a cathode module. The upper connecting rods and insulators are built into the insulation box, which serves as an explosion-proof insulation.

[0004] However, during the installation of the aforementioned insulators, assembly errors between the insulators and the insulation box may result in the insulators not being perfectly perpendicular, affecting the perpendicularity of the lower connecting rod and the corona electrode, thus impacting the ionization effect. Therefore, it is urgent to design an explosion-proof insulation box structure for electrostatic precipitators to solve the problem of not being able to guarantee the perpendicularity of the insulators during assembly. Utility Model Content

The end of the pin has a first threaded hole. The locking pin has a thread. The locking pin passes through the first threaded hole and is screwed to the first threaded hole via the thread.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] This utility model provides a structure for an explosion-proof insulating box for an electrostatic precipitator, the structure of which is as follows: Figure 1 - Figure 4As shown, the device includes a housing 100, a pad 200, and a first fastening mechanism 300. The housing 100 is used to house the insulator 1. The pad 200 is elastic and fixedly connected to the housing 100, and is used to abut against the bottom surface of the boss 11 of the insulator 1. The first fastening mechanism 300 includes at least three support rods 310, at least three pressure blocks 320, and at least three first fasteners 330. Each support rod 310 is arranged vertically on the side of the insulator 1 in a circular array structure. Each pressure block 320 is slidably connected to each support rod 310. Each first fastener 330 is detachably connected to each support rod 310. The first fastener 330 has a fastened state that is fastened to the support rod 310 and an active state that can slide along the support rod 310 to push the pressure block 320 downward to press the boss 11 of the insulator 1.

[0020] In use, the opening at the bottom of the housing 100 is aligned with the mounting port on the cylinder of the electrostatic precipitator, and connected via a flange. Then, the insulator 1 is installed. During installation, the insulator 1 is placed inside the housing 100, with the bottom surface of the protrusion 11 of the insulator 1 resting on the pad 200. At this time, the pad 200 can abut against the bottom surface of the protrusion 11 of the insulator 1. The perpendicularity of the insulator 1 is observed, and the first fasteners 330 of the first fastening mechanism 300 are operated according to the perpendicularity of the insulator 1. When the first fastener 330 is in operation, it slides downward along the support rod 310, which can push the pressure block 320 to press down on the boss 11 of the insulator 1. This allows adjustment of the level of the boss 11 of the insulator 1, thereby adjusting the verticality of the insulator 1. The explosion-proof insulation box structure of this electrostatic precipitator can overcome the assembly error problem between the insulator 1 and the insulation box. During the assembly of the insulator 1, the verticality of the insulator 1 can be guaranteed, thereby ensuring the verticality of the lower connecting rod 3 and the corona electrode, and ensuring the ionization effect.

[0022] As a preferred embodiment, please refer to Figure 1 and Figure 2The housing 110 is a tubular structure, comprising a lower pipe section 111, an upper pipe section 112, and an upper cover plate 113. The opening at the bottom of the upper pipe section 112 is detachably connected to the opening at the top of the lower pipe section 111 via a flange. The upper cover plate 113 is detachably fitted onto the opening at the top of the upper pipe section 112 via a flange.

When installing the insulator 1, the insulator 1 is placed inside the lower pipe section 111, with the bottom surface of the boss 11 of the insulator 1 resting on the pad 200. At this time, the pad 200 can abut against the bottom surface of the boss 11 of the insulator 1. One person enters the cylinder of the electrostatic precipitator to observe the verticality of the upper connecting rod 2. Another person... Standing outside the cylinder of the electrostatic precipitator, the verticality of the insulator 1 can be adjusted by operating the first fasteners 330 of the first fastening mechanism 300 according to the verticality of the upper connecting rod 2. This allows for the adjustment of the verticality of the upper connecting rod 2. Finally, the opening at the bottom of the upper pipe section 112 is connected to the opening at the top of the lower pipe section 111, and the connection is detachable via a flange. The upper cover plate 113 is then placed over the opening at the top of the upper pipe section 112 and detachably connected via a flange. The structure of the housing 110 facilitates the operation of the first fasteners 330 of the first fastening mechanism 300, preventing the user from inserting their head inside the housing 110 to operate the first fasteners 330.

[0023] As a preferred embodiment, please refer to Figure 1 and Figure 3 Both the base 120 and the pad 200 are annular structures.

The annular structure of the pad 200 can also play a sealing role, preventing the gas inside the cylinder of the electrostatic precipitator from passing through the base 120 and entering the space above the base 120, and then leaking into the outside air.

[0024] In a preferred embodiment, the pad 200 is a rubber ring.

The nut is sleeved on the screw rod and threadedly connected to the screw rod. When the nut is rotated in the forward direction, the nut can move downward along the screw rod, thereby pushing the pressure block 320 downward, so that the pressure block 320 can press down on the boss 11 of the insulator 1, thereby adjusting the level of the boss 11 of the insulator 1.

[0027] As a preferred embodiment, please refer to Figure 3 The pressure block 320 has a through hole at one end and is slidably sleeved on the support rod 310 through the through hole. The support rod 310 can guide the up and down movement of the pressure block 320.

[0028] As a preferred embodiment, please refer to Figure 3 A ramp is provided on the bottom surface of the other end of the pressure block 320, and the ramp abuts against the top surface of the boss 11 of the insulator 1.

The second fasteners 420 are distributed in a ring array structure and are all connected to the upper end of the lower connecting rod 3. The end is detachably connected. The second fastener 420 has a fastened state that is fastened to the lower connecting rod 3 and a movable state that can slide radially along the lower connecting rod 3 to abut against the side wall of the upper connecting rod 2. In use, the opening at the bottom of the housing 100 is connected to the mounting port on the cylinder of the electrostatic precipitator, and then connected via a flange. Then, the insulator 1 is installed. When installing the insulator 1, the insulator 1 is placed inside the housing 100, and the bottom surface of the boss 11 of the insulator 1 is placed on the pad 200. At this time, the pad 200 can abut against the bottom surface of the boss 11 of the insulator 1. Observe the insulator 1. To check the verticality of insulator 1, rotate each nut of the first fastening mechanism 300. When the nut is rotated, it slides downward along the support rod 310, pushing the pressure block 320 downward to press the boss 11 of insulator 1, thereby adjusting the horizontality of the boss 11 of insulator 1 and thus adjusting the verticality of insulator 1.

The second fasteners 420 will slide radially along the lower connecting rod 3 and abut against the side wall of the upper connecting rod 2. Since the lower connecting rod 3 can swing relative to the upper connecting rod 2, the verticality of the lower connecting rod 3 can be adjusted. The explosion-proof insulation box structure of this electrostatic precipitator can also overcome the assembly error problem between the lower connecting rod 3 and the upper connecting rod 2. When assembling the lower connecting rod 3, the verticality of the lower connecting rod 3 can be guaranteed, thereby ensuring the verticality of the corona electrode and ensuring the ionization effect.

[0033] As a preferred embodiment, please refer to Figure 1 and Figure 2 The lower pipe section 111 of the housing 110 is provided with the manhole 130. The housing 110 also includes a side cover plate 114, which is detachably covered by the manhole 130 via a flange. Since the second fastening mechanism 400 is located inside the lower pipe section 111 of the housing 110, the manhole 130 is opened on the lower pipe section 111 to facilitate the operation of the connector 410 and each of the second fasteners 420 through the manhole 130.

Then, the insulator 1 is installed. During installation, the insulator 1 is placed inside the lower pipe section 111 of the housing 110, with the bottom surface of the boss 11 of the insulator 1 resting on the pad 200. At this time, the pad 200 can abut against the bottom surface of the boss 11 of the insulator 1. One person enters the cylinder of the electrostatic precipitator to observe the verticality of the upper connecting rod 2, while another person stands outside the cylinder of the electrostatic precipitator to operate the screws of the first fastening mechanism 300 according to the verticality of the upper connecting rod 2. When the nut is rotated clockwise, it moves downward along the screw, thereby pushing the pressure block 320 downward. This pressure block 320 presses down on the boss 11 of the insulator 1, adjusting the levelness of the boss 11 and thus adjusting the verticality of the insulator 1. Then, the lower connecting rod 3 is installed. During installation, the upper end of the lower connecting rod 3 extends into the housing 100, and the upper end of the lower connecting rod 3 is fitted onto the lower end of the upper connecting rod 2.

Then, the pin 411 is inserted through the first and second insertion holes, and... The locking pin 412 passes through the first threaded hole and is screwed into the first threaded hole via its thread. The end cap of the pin 411 and the locking pin 412 form a radial limit, realizing the connection between the lower connecting rod 3 and the upper connecting rod 2. Since the diameter of the pin 411 is smaller than the diameter of the first and second insertion holes, when the lower connecting rod 3 and the upper connecting rod 2 are connected by the pin 411, the lower connecting rod 3 can swing relative to the upper connecting rod 2. One person enters the cylinder of the electrostatic precipitator to observe the verticality of the lower connecting rod 3, and another person stands outside the cylinder of the electrostatic precipitator to operate the second fastening mechanism 400 according to the verticality of the lower connecting rod 3. By rotating each of the bolts, the inner end of the bolt abuts against the side wall of the upper connecting rod 2, thereby adjusting the verticality of the lower connecting rod 3. This explosion-proof insulation box structure for the electrostatic precipitator overcomes the assembly error problem between the insulator 1 and the insulation box. During the assembly of the insulator 1, the verticality of the insulator 1 is guaranteed, thus ensuring the verticality of the lower connecting rod 3 and the corona electrode, guaranteeing the ionization effect. Furthermore, this explosion-proof insulation box structure for the electrostatic precipitator also overcomes the assembly error problem between the lower connecting rod 3 and the upper connecting rod 2. During the assembly of the lower connecting rod 3, the verticality of the lower connecting rod 3 is guaranteed, thus ensuring the verticality of the corona electrode, guaranteeing the ionization effect.

[0038] The explosion-proof insulating box structure for an electrostatic precipitator provided by this utility model has the following beneficial effects: (1) The structure of the box body 110 makes it easy for people to operate each of the first fasteners 330 of the first fastening mechanism 300, and avoids people from putting their heads into the box body 110 to operate each of the first fasteners 330 of the first fastening mechanism 300. (2) The explosion-proof insulation box structure of this electrostatic precipitator can overcome the assembly error problem between the insulator 1 and the insulation box. When the insulator 1 is assembled, the verticality of the insulator 1 can be guaranteed, thereby ensuring the verticality of the lower connecting rod 3 and the corona electrode, and ensuring the ionization effect. (3) The explosion-proof insulation box structure of this electrostatic precipitator can also overcome the assembly error problem between the lower connecting rod 3 and the upper connecting rod 2. When assembling the lower connecting rod 3, the verticality of the lower connecting rod 3 can be guaranteed, thereby ensuring the verticality of the corona electrode and ensuring the ionization effect.
