Abstract
The utility model relates to a large-scale cloth screen with a self carried bypath. In the prior art, the temperature bearing of a filtering bag adopted by a large-scale cloth screen is limited. In industrial application, because abnormal conditions or accidents during technology running occur, the condition that flue gas temperature is beyond the use range of the filtering bag can occur, a bypath flue increase method is adopted in general at home and abroad, and in this way, cost and occupation area can be increased. Because field limitation, an ideal effect is difficulty to realize. The inlet point of the large-scale cloth screen is provided with an air-stream reversing box by the utility model. When the flue gas temperature is beyond the stated temperature of the filtering bag, an air-stream reversing valve is opened rapidly through electric control, high temperature flue gases are expelled from the cloth screen through a self gas-out flue of the cloth screen, and the filtering bag obtains protection. Thereby, the utility model does not need increasing field areas and has the advantages that structure is simple, use is reliable, the stable running of the cloth screen can be ensured, pollution is reduced and environment is protected.
Description
One, technical field:
The utility model relates to a kind of large-scale bagroom that carries bypass.
Two, technical background:
In the prior art, the filter bag heatproof that large-scale bagroom adopted is restricted, in commercial Application, because abnormal conditions or accident appear in the technology operation, the situation that flue-gas temperature surpasses the scope of application of filter bag can appear, if untimely taking measures will make whole filter bags burn out, cause very large economy loss, and cause environmental pollution.Home and overseas generally takes to increase the way of bypass flue, like this, will increase cost and increase floor space, have since place restriction be difficult to realize; The way of taking to join cold wind that has can have a strong impact on technology like this and normally move, and increases the filter bag load, reduces service life.
Three, summary of the invention:
The utility model proposes a kind of site area that do not need to increase for addressing the above problem, and when flue-gas temperature surpasses setting, makes flue gas discharge the large-scale bagroom of dust-precipitator through the flue of giving vent to anger of dust-precipitator itself by the airflow-reversing case.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of large-scale bagroom that carries bypass comprises large-scale bagroom, and its special character is: import 5 places of described large-scale bagroom 3 are provided with an airflow-reversing case 1; On the described airflow-reversing case 1 airflow-reversing valve 2 is set, airflow-reversing case 1 directly communicates with the flue 6 of giving vent to anger of dust-precipitator through airflow-reversing valve 2; On the described dust-precipitator 3 valve 4 is set, flue gas communicates with the flue 6 of giving vent to anger of dust-precipitator by valve 4 after filter bag filters.
The above-mentioned flue 6 of giving vent to anger is dust-precipitator bypass flue.
The airflow-reversing valve 2 that above-mentioned airflow-reversing case 1 is provided with is 2-4.
The utility model is with respect to prior art, and its advantage is as follows:
1, the utility model is simple in structure, uses reliably, can guarantee the stable operation of bag collector, reduces and pollutes, the protection environment.
2, the utility model adopts the flue of giving vent to anger of dust-precipitator itself, thereby does not need to increase the bypass flue, does not increase floor space and reduces cost.
Four, description of drawings:
Fig. 1 is the utility model structure chart;
Fig. 2 is a sectional structure chart of the present utility model;
Fig. 3 is the left view of figure one;
Fig. 4 is the vertical view of figure one;
Five, the specific embodiment:
In course of normal operation, when dusty gas enters bagroom, filter by filter bag, dust is isolated in the filter bag surface by filter bag, and clean gas enters the flue of giving vent to anger and discharges outside the dust-precipitator by behind the filter bag, makes gas purification.In industry, bagroom is operation continuously, and the filter bag heatproof is conditional, if flue-gas temperature surpasses the filter bag maximum temperature, filter bag will be burnt out, and economic loss is very big, and influences whole industrial production, pollutes to environment.
The utility model is that the import department at large-scale bagroom is provided with an airflow-reversing case; when flue-gas temperature surpasses the temperature of filter bag regulation; make high-temperature flue gas discharge dust-precipitator by the automatically controlled airflow-reversing valve of opening rapidly, filter bag is protected by the flue of giving vent to anger of dust-precipitator itself.
Referring to Fig. 1 to Fig. 4, the described large-scale bagroom that carries bypass is provided with airflow-reversing valve 2 for to be provided with an airflow-reversing case 1 at import 5 places of large-scale bagroom 3 on the described airflow-reversing case 1, directly communicates with the flue 6 of giving vent to anger of dust-precipitator; On the described large-scale bagroom 3 valve 4 is set, flue gas enters flue 6 discharges of giving vent to anger through the valve 4 that filter bag filters through dust-precipitator.When flue-gas temperature surpassed the temperature of filter bag regulation, by the automatically controlled airflow-reversing valve 2 of opening rapidly, shut off valve 4 made high-temperature flue gas discharge dust-precipitator by the flue 6 of giving vent to anger of dust-precipitator itself, and filter bag is protected.1-2 road sealed change valve can be set in the airflow-reversing case of the present utility model, and its reversal valve can be 2-4.
Dust-precipitator body of the present utility model can be blowing type, the big cloth bag of blowback wind or gas tank blowing type; when flue-gas temperature surpasses the temperature of filter bag regulation; by the automatically controlled airflow-reversing valve of opening rapidly; make high-temperature flue gas discharge dust-precipitator, strainer is protected by the flue of giving vent to anger of dust-precipitator itself, simple in structure; use reliable; can guarantee the stable operation of bag collector, reduce and pollute, the protection environment.
