Description

Technical Field

[0001] The utility model relates to the technical field of electric tar precipitator porcelain bottle preheating, and is an electric tar precipitator porcelain bottle preheating device. Background Art

[0002] An electric tar precipitator removes tar and dust in gas to purify the gas, enabling subsequent equipment to operate normally in a long cycle and achieving the effects of energy conservation and consumption reduction. It mainly consists of the following components: a straight shell; a cylindrical precipitation electrode system arranged axially inside; a set of tensioned wires as corona electrodes, and in addition, there are auxiliary devices such as instruments, control power supply, and power transmission. The coke oven gas containing tar and dust enters the electric tar precipitator through the inlet on the outer shell below the precipitation electrode, and then the gas is evenly distributed by the gas distributor. When the gas passes through the electrode area, the tar and dust in the gas are separated under the action of high-voltage static electricity. The purified gas leaves the electric tar precipitator through the upper outlet, and the separated tar and dust flow downward along the cylindrical precipitation electrode and are discharged from the bottom. The high-voltage direct current from the high-voltage rectifier is sent to the hanger of the discharge system in the insulating box through the high-voltage cable, and the discharge system is supported by the porcelain bottle in the insulating box. The upper hanger and the lower hanger are used to ensure that each corona electrode is located at the center of each electric field space. To prevent the porcelain bottle surface from condensing, heating protection is set in the insulating box.

[0003] However, the electric tar precipitator insulating box uses a direct heating method with heating tubes. Due to the long service time of the equipment insulating box and the porcelain bottle, the local preheating level fails to meet the specified requirements, and the porcelain bottle is prone to breakage due to uneven heating. The preheating porcelain bottle of the electric tar precipitator is frequently damaged, resulting in the abnormal operation of the electric tar precipitator, a high oil content rate in the gas, corrosion of the equipment and pipelines, poor hygiene of the equipment and pipeline bodies, and the need to stop the furnace for defect elimination and leakage repair, which affects the safe and stable operation of the semi-coke furnace. Summary of the Invention

[0004] The utility model provides an electric tar precipitator porcelain bottle preheating device, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problem that the existing electric tar precipitator directly heats the porcelain bottle, resulting in uneven heating of the porcelain bottle and easy breakage.

[0005] The technical solution of the utility model is realized by the following measures: An electric tar precipitator porcelain bottle preheating device, comprising an electric tar precipitator body, porcelain bottles, insulating boxes and preheating components. Four porcelain bottles are circumferentially and spacedly distributed on the outer side of the upper part of the electric tar precipitator body. An insulating box with a lower end opening and an upper end closed is fixedly installed on the outer side of each porcelain bottle. A preheating component is provided on the outer side of each insulating box. The preheating component located in the front right is the main preheating component. The main preheating component includes a support seat, a hinge shaft, a first protective shell, a second protective shell, an electric heater and a connecting piece. A circular support seat is detachably and fixedly installed on the outer side of the lower part of the insulating box.

A plurality of first rotating sleeves and second rotating sleeves are sleeved on the outer side of the hinge shaft. The first protective shell and the second protective shell are in the shape of semi-circles with opposite openings. The rear side of the left part of the first protective shell is fixedly installed together with the outer side of the front part of each first rotating sleeve. The front side of the left part of the second protective shell is fixedly installed together with the outer side of the rear part of each second rotating sleeve. At least one connecting piece is vertically spaced between the rear side of the right part of the first protective shell and the front side of the right part of the second protective shell. A plurality of electric heaters are circumferentially and spacedly distributed on the inner sides of the lower parts of the first protective shell and the second protective shell. A spacing is provided between each electric heater and the outer side of the insulating box. The preheating components located in other positions have the same structure as the main preheating component.

[0006] The following is a further optimization and / or improvement of the above-mentioned technical solution of the utility model:

[0007] An inspection hole penetrating up and down may be provided at the upper end of the above-mentioned insulating box. An installation cover plate is fixedly installed at the upper end of the insulating box corresponding to the position of the inspection hole. An annular upper baffle is fixedly installed on the outer side of the upper part of the insulating box corresponding to the upper end position of the first protective shell.

[0008] The above-mentioned connecting piece may include a connecting nut, a connecting ring and a connecting screw. A plurality of connecting nuts are fixedly installed at the upper and lower intervals on the right rear side of the first protective shell. A connecting ring is fixedly installed on the right front side of the second protective shell corresponding to each connecting nut position. A connecting screw with a front end screwed into the corresponding connecting nut is sleeved in each connecting ring.

[0009] The above-mentioned main preheating component may further include a control module, a mounting seat and a temperature sensor. An installation groove with an opening forward is provided on the outer side of the right part of the second protective shell. A mounting seat with a front side fixedly installed together with the right rear side of the first protective shell is provided in the installation groove.

When the electric heater works, it can heat the outside of the insulating box, so as to keep a certain temperature inside the insulating box, thereby preventing the porcelain insulators in the insulating box from condensing. The heaters can be evenly distributed according to the setting of the porcelain insulators to realize uniform heating of the insulating box. Electric heating can directly generate heat inside the object to be heated, so the thermal efficiency is high and the heating speed is fast. Constant temperature heating can also be realized during the heating process. Compared with straight tube heating, the heating cost of the electric heater is lower. Through such a setting, the condensation of the porcelain insulators can be avoided, which can reduce the failure rate of the electrocatalytic tar precipitator and extend the normal operation time.
