The access door structure can effectively block heat convection, heat losses of the access door are reduced, meanwhile, the supporting function is achieved, and the access door structure can be used for high-temperature dust removal devices in cement, waste incineration, thermal power, steel, nonferrous metal, chemical engineering and other industries.
Description
Technical field
The utility model designs the parts in a kind of pulse-jetting type hot precipitator, is specifically related to a kind of top access door of the pulse-jetting type hot precipitator for hot environment flue gas purifying equipment.
Background technology
Current, high-temperature dust removal technology is also in laboratory or pilot scale stage, and traditional dust remover roof access door is continued to use top cover more and offered seal groove, and in seal groove, fill out and put the conventional encapsulant of sealing, then by press strip press seal.Be subject to that ash-laden gas temperature is high, flue gas corrosion is strong, the inhomogeneous impact that the factor such as jams on during the large and installation and repairing of deduster body vibrations during arteries and veins spray, traditional roof door lid filler easily comes off or is easily aging, causes traditional top cover to leak out seriously, system energy consumption increase.
Utility model content
For above-mentioned problems of the prior art, the purpose of this utility model is to propose a kind of access door structure for pulse-jetting type hot precipitator, it has good sealing performance, can prevent that outside cold wind from entering the increase that deduster causes system hear rate and power consumption.
the utility model adopts following technical scheme:for an access door structure for pulse-jetting type hot precipitator, comprise access door and sealing posting; Described access door comprises top cover and inner bag, described inner bag is concave, in its chamber, establish isolation layer, inner bag upper edge is connected on the back side periphery of top cover, described sealing posting comprises the U-lag that airtight and watertight padding is housed, and described U-lag is located on the riser being connected with air-purifying chamber top board, is configured for the framework of access door peripheral sealing location, the card of described top cover is combined in the airtight and watertight padding of U-lag, forms and is flexible coupling with U-lag.
Described access door periphery is established several hold down gags and is fixed.
Described hold down gag consists of press strip, bolt and nut, and described press strip is pressed on top cover by bolt and nut, and described bolt bottom is fixed on air-purifying chamber top board.
Described airtight and watertight padding is comprised of two parts, and inner side adopts inorganic high-temperature resistant heat-barrier material, and outside guaranteeing, airtight and watertight padding is worked at 250 ℃ of temperature, and outside adopts elevated-temperature seal filler.As shown from the above technical solution: an inner bag of design in access door top cover, inner filling with insulation material, can effectively block thermal convection current, when reducing access door heat leakage, plays a supporting role again.U-lag is used in conjunction with access door top cover, is not integrated with access door, plays sealing positioning action, in groove
adopttwo kinds of airtight and watertight paddings, inner side filler plays heat-blocking action, and outside filler has good elasticity, guarantees sealing.On access door top cover, design many press strips, in all directions, prevent top cover distortion, play good sealing function.
the beneficial effects of the utility model:can effectively block thermal convection current, when reducing access door heat leakage, play a supporting role again, can be used in the industry high-temperature dust removal equipment such as cement, waste incineration, thermoelectricity, iron and steel, non-ferrous metal, chemical industry.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, be the positional structure schematic diagram of the utility model in hot precipitator; Access door 9 is positioned at the top of deduster body 8.
As in Figure 2-4, comprise access door 9 and sealing posting; Access door 9 consists of top cover 2 and inner bag 5.Inner bag 5 is concave, establishes isolation layer 4 in concave shaped cavity.Inner bag 5 upper edges are fixed in the back side periphery of top cover 2.Inner bag adopts good rigidity, and the metal material that density is little is made.Sealing posting comprises the U-lag 303 that airtight and watertight padding 1 is housed.U-lag 303 is welded on the riser 304 being connected with air-purifying chamber top board 6, is configured for the framework of access door peripheral sealing location.The card of top cover 2 is combined in the airtight and watertight padding 1 of U-lag 303, forms and is flexible coupling with U-lag.It is fixing that access door 9 periphery corners establish a plurality of hold down gags 3.Hold down gag consists of press strip 301, bolt 302 and nut, and press strip 301 is pressed on top cover 2 by bolt and nut, and bolt 302 bottoms are welded on air-purifying chamber top board 6.Hold down gag can prevent top cover distortion in all directions, plays good sealing function.Airtight and watertight padding 1 is comprised of two parts, and inner side adopts inorganic high-temperature resistant material, and inner side filler drops to internal temperature in the filler working range of outside, mainly plays heat-blocking action, and temperature resistant range is greater than 600 ℃.The airtight and watertight padding in outside adopts the heat insulating material containing organic principle, selects the material of good springiness under high temperature, plays sealing and heat-blocking action simultaneously; U-shaped groove and top cover are flexible coupling by airtight and watertight padding.
The selection of above structure and material, while guaranteeing that deduster normally moves, the top access door cold wind that do not bleed.During maintenance, inner side of liner heat-barrier material can not shrivel.Inner bag can effectively be blocked thermal convection current, when reducing access door heat leakage, plays a supporting role again.
