Abstract
The invention discloses a check drain valve of a heat accumulator, relating to the technical field of waste heat recovery of flue gas of an industrial kiln. The check drain valve comprises a sealing cylinder, wherein the top and the bottom of the sealing cylinder are provided with a taper cavity respectively; a floating ball is arranged in the sealing cylinder; the upper end of the sealing cylinder is provided with a liquid collection cone for connecting the heat accumulator; and the lower end of the sealing cylinder is provided with a connecting end for connecting a rotary liquid sealing pipe. The liquid collection cone at the upper end of the check drain valve is connected with flue gas waste heat recovery equipment, and the lower end of the check drain valve is connected with the rotary liquid sealing pipe; since liquid is filled in the rotary liquid sealing pipe in use, liquid also exists in the sealing cylinder communicated with the rotary liquid sealing pipe; and under the action of the floating ball, no phenomenon of air leakage of a drainage system is guaranteed.
Description
Technical field
The invention belongs to the Energy-saving in Industrial Furnaces technical field, be specifically related to industrial furnace flue gas waste heat recovery technical field.
Background technique
The recovery of industrial furnace combustion product gases waste heat has steel tube type, fin tube type, top tubular type, hot tube, the form such as board-like.Various heat recovery heat exchangers are gaseous state, as reaching liquid phase state, serious dew point corrosion will occur, cause waste heat recovering device to lose efficacy, heat accumulation type trans-critical flue gas waste heat recovery equipment (the patent No.: 200910028403.6), (patent No.: revolution liquid-seal type non-return structure has been adopted in discharge opeing 200910028334.9) to the heat accumulating type heat-exchanger, in engineering reality, because the fluctuation of stack draught or blower or induced draught fan pressure, can cause seal failure, cause drainage system to leak out, and then destroy the heat recovery effect.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide the heat regenerator of a kind of industrial furnace combustion product gases heat recovery to stride the check valve of critical liquid-discharging tube.
The present invention includes a upper and lower sealing drum that is respectively equipped with the tapering inner chamber, in described sealing drum, ball float is set, the upper end of described sealing drum is provided with for the liquid collecting cone that connects thermal accumulator, and the lower end of described sealing drum is provided with to be used and the connecting end that is connected the rotary type liquid sealing pipe.
The liquid collecting cone of the present invention upper end is connected with flue gas waste heat recovery equipment, the lower end is connected with the revolution liquid sealing pipe, owing in the revolution liquid sealing pipe, liquid is housed when using, so, with also had liquid in the sealing drum of the present invention that is communicated with of revolution liquid sealing pipe, under the effect of ball float, the system that guaranteed the phenomenon that drainage system leaks out can not occur.
When the suitable thermal accumulator liquid collecting centrum of the liquid of trans-critical flue gas waste-heat recoverer condensation advances downstream to floater seal section of the present invention, ball float sinks down into the tenesmus section by gravity and guarantees the unimpeded of upper sealing surface liquid collecting, during incipient stage rotary type fluid-tight end no liquid, the lower conical surface of the tapering inner chamber that ball float sinks and sealing drum is interior is fitted and is formed sealing, this moment, sealing drum compiled liquid formation liquid level, ball float is risen open the sealing of the conical surface under it, make the thermal accumulator liquid collecting dirty smoothly.
When rotary type fluid-tight section is full of liquid collecting, liquid level with ball float is risen under the effect of buoyancy, open the sealing of lower end conisphere face, make the heat retainer liquid collecting dirty smoothly.
When in the heat accumulator system because system pressure fluctuation when (as blow the situation such as ash occur), system produces negative pressure, forms revolution fluid-tight liquid and takes out in system, and liquid level raises, ball float rises, and makes the upper conical surface applying of the interior tapering inner chamber of ball float upper end and sealing drum form sealing.
When the revolution fluid-tight did not form fluid-tight and is no liquid, the air-flow of pumpback was taken out ball float, made the upper conical surface of the tapering inner chamber in ball float upper-end surface and the sealing drum fit to form and sealed.
The present invention adopts ball float, utilize air-flow and liquid collecting to control the rubber mass ball float, form corresponding sealing, be marked with expandable plastic in the sealed spheroid, alleviating ball density, simultaneously can fixed volume, when temperature variation, larger variation does not occur in its volume, and it is simple in structure, sealing is reliable, save material.
In addition, sealing drum of the present invention by the direct tube section at middle part and be connected to direct tube section up and down upper cone section and the lower cone section at two ends form, the height of sealing drum is h
1, the radius of ball float is d
2System enters hot air flow when preventing that ball float from changing in system; sphere volume is expanded with heat and contract with cold; cause normal activity in the floater seal cylinder; guarantee accurately to realize sealing function with this structure; and leave suitably conservative amount, with 2d2 〉=h1 〉=1.5d2, control direct tube section sectional area guarantees the circulation area of liquid collecting.
The diameter of described sealing drum is d
1, the diameter of upper cone section upper end and the diameter of lower cone section lower end are respectively d
3, d
1 2=d
2 2+ d
3 2For guaranteeing under any circumstance circulation area of sealing drum discharge opeing, require the entire body sectional area to deduct the spheroid sectional area and equate with lower liquid-discharging tube area, in order to avoid form the liquid resistance; The amount of liquid of condensation can reduce when system's high temperature, works as d
1 2=d
2 2+ d
3 2The time can make this structure can not form liquid resistance.
In addition, in order to improve the conical surface seal effect, the interior cone angle of the epimere of described sealing drum inner chamber is 45 ± 15 °.
The interior cone angle of the hypomere of described sealing drum inner chamber is 45 ± 15 °.
