Abstract
The utility model relates to a sewage discharge structure at the bottom of a chimney. The sewage discharge structure comprises a support used for supporting the sewage discharge structure, wherein the support is installed on an ash deposition platform, and a sewage and liquid discharge funnel with a furled lower port is arranged below the ash deposition platform. The sewage discharge structure is characterized in that an outlet is formed below the sewage and liquid discharge funnel and is connected with a diversion pipe extending into a sewage discharge effusion box at the lower part; a pipe orifice of a liquid discharge pipe is arranged above the wall surface of the sewage discharge effusion box, and a sewage clearing port is arranged below the wall surface; and a port of the diversion pipe extending into the sewage discharge effusion box is kept in the position between the pipe orifice of the liquid discharge pipe and the sewage clearing port. The sewage discharge structure abandons the existing pipe diameter structure and is divided into two parts used for respectively clearing the deposited liquid and the deposited ash by the diversion pipe; the height of the diversion pipe is controlled between the two ports as a liquid seal; the overflowed deposition liquid can be discharged from the pipe orifice of the liquid discharge pipe and can not flow backwards; and the sewage clearing port at the bottom part is convenient for the deposition of flue gas and dust and also is convenient for people to clean periodically.
Description
[technical field]
The utility model relates to the chimney treatment technology, relates in particular to a kind of chimney bottom pollution discharge structure.
[background technology]
The chimney that large-scale fuel type industrial plant all disposes specialty usually is used for smoke evacuation, be provided with in the chimney and be provided with the dust stratification platform in the chimney and be used for flue dust soil and the long-pending flow liquid that sedimentation burning brings, cross beam under the dust stratification platform is built with chimney, be generally xoncrete structure, dust stratification platform formwork secondary on cross beam is built, the 3-5cm expansion joint is arranged between platform collar tie beam and the chimney, fill out loose fill type insulant in the seam when laying bricks, the dust stratification platform is provided with security bar.Need after desulfurization, enter atmosphere during chimney emission, and the exhaust gas temperature after the desulfurization is generally at 40-50 ℃, water content height, high humidity in the flue gas, the plume rise diffusivity is low, therefore form water smoke in chimney, flue gas has the droplets agglomerate that contains acid in a large number to come out below dew point, not only contaminated environment but also bring corrosion to equipment, therefore, a large amount of dust stratification liquid, dust stratification things need be discharged chimney as soon as possible on the dust stratification platform.
Dust stratification liquid on the existing dust stratification platform and dust stratification thing are generally discharged chimney by blow-off pipe is set in chimney bottom, least significant end at chimney, be designed to a L type, flue dust gas enters from the L lower end, vertical chimney discharges from top, just be provided with pollution discharge structure in the turning point, existing pollution discharge structure all is the blowdown drainage hopper that adopts a collection dust and hydrops last, blowdown drainage hopper bottom connects the pipeline of bending, become the outlet of blowdown, because be subjected to the restriction of caliber, chimney bottom is easy to be stopped up by dust stratification.
[summary of the invention]
The utility model provides a kind of caliber size restriction that is not subjected in order to solve above technical problem, is convenient to the chimney pollution discharge structure with flue dust and hydrops discharge.
The technical solution of the utility model is: a kind of chimney bottom pollution discharge structure, comprise the support and the dust stratification platform that support pollution discharge structure, described support is installed on the dust stratification platform, it below the dust stratification platform blowdown drainage hopper that end opening draws in, it is characterized in that, below described blowdown drainage hopper, an outlet is arranged, described outlet connects a mozzle that extend into below blowdown hydrops case, on the wall of described blowdown hydrops case, the top is provided with the discharging tube mouth of pipe, be provided with soil cleaning port below described blowdown hydrops wall, the port when described mozzle extend in the blowdown hydrops case remains on the position between the discharging tube mouth of pipe and the soil cleaning port.
The described blowdown drainage hopper side's of being taper or taper shape.
Described outlet is to engage by a flange-interface to be connected with mozzle.
The node place of described dust stratification platform and chimney bottom is provided with the slope with certain slope.
Above described blowdown hydrops case, have and can hold the cover plate that mozzle passes.
Lower surface at the dust stratification platform has the fixedly ear handle that cooperates with support, and described fixedly ear is by the expansion bolt that is symmetrically distributed the blowdown drainage hopper being fixed on the dust stratification platform.
Soil cleaning port exceeds the bottom surface of described blowdown hydrops case.
The beneficial effects of the utility model: abandoned original caliber structure, adopt mozzle to divide two places up and down, clear respectively row's hydrops and laying dust, the height of mozzle is controlled between two mouths, can be used as fluid-tight, the hydrops of spill-over just can and can not flow backwards from the discharge of the discharging tube mouth of pipe, and the soil cleaning port of bottom then makes things convenient for the sedimentation of flue dust, and making things convenient for the people is periodic cleaning.
[description of drawings]
Fig. 1 is the utility model one example structure schematic diagram.
Wherein: 1, dust stratification platform; 2, blowdown drainage hopper; 3, outlet; 4, mozzle; 5, blowdown hydrops case; 6, the discharging tube mouth of pipe; 7, soil cleaning port; 8, port; 9, cover plate; 10, fixing ear handle; 11, expansion bolt; 12, flange-interface.
[specific embodiment]
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.
Embodiment 1: a kind of chimney bottom pollution discharge structure, comprise the support and the dust stratification platform that support pollution discharge structure, described support is installed on the dust stratification platform 1, it below dust stratification platform 1 the blowdown drainage hopper 2 that end opening draws in, it is characterized in that, one outlet 3 is arranged below described blowdown drainage hopper 2, described outlet 3 connects a mozzle 4 that extend into below blowdown hydrops case 5, on the wall of described blowdown hydrops case 5, the top is provided with the discharging tube mouth of pipe 6, be provided with soil cleaning port 7 below described blowdown hydrops case 5 walls, the port 8 when described mozzle 4 extend in the blowdown hydrops case 5 remains on the position between the discharging tube mouth of pipe 6 and the soil cleaning port 7.
