Abstract
A preheating apparatus for a filtering chamber of a bag-type strainer relates to industrial dedusting technology. The utility model has the technical proposal that an air-supply pipe 1 of a filtering chamber of a bag-type strainer is provided with a hot air branch pipe 4 which is connected with the air-supply pipe; the opening of the hot air branch pipe is provided with a valve 7; a spring 8 is arranged between the valve and the wall of the hot air branch pipe; the inner cavity of the hot air branch pipe is provided with an electrical heating element 5; the hot air branch pipe is connected with a blower; connection terminals (a), (b) and (c) of an electric control box 10 are respectively connected with a temperature measurement head 9 of a discharge pipe 3 of the filtering chamber, the electrical heating element 5 of the hot air branch pipe and the blower 6. Adopting new technical measures, when the utility model is started, the blower and the electric heating element of the hot air branch pipe are firstly actuated by an electric control circuit to open the valve of the hot air branch pipe, and then hot air enters the filtering chamber of the strainer passing through the air-supply pipe of the filtering chamber to make the hot air in the filtering chamber even so as to effectively prevent dew condensation and overcome the defects of uneven heating, easy burnout of heating elements, etc. existing in the prior art.
Description
Technical field: the utility model relates to the industrial dedusting technology, relates generally to pulsed jet cloth filter, specifically is meant sack cleaner filter chamber preheating device.
Background technology: when sack cleaner shelve a period of time, particularly when microthermal climate is enabled, high-temperature flue gas enters cold conditions deduster filter chamber and is easy to generate dewfall, this causes filter chamber inwall and filter bag knot dirt easily, influences dust removing effects.Be anti-filter chamber dewfall, existing solution is in the filter chamber bottom, promptly bottom the filter bag and between more than the ash bucket electrical heating elements is set, and drops into electrical heating preheating filter chamber during startup earlier.There is following deficiency in this way, and the one, it is serious that heating is located at the interior laying dust of filter chamber, both influenced heat exchange, the easy again cause thermal damage of crossing, the 2nd, no matter what position heating is installed in, often all thermal convection current is not smooth, makes filter chamber heating-up temperature inequality, the anti-condensation weak effect.
Summary of the invention: goal of the invention of the present utility model, be deficiency at pre existing heating anti-condensation method, the sack cleaner filter chamber preheating device of an improvement scheme is provided.
For reaching the measure that above-mentioned purpose takes be, in sack cleaner filter chamber blast pipe 1 hot blast manifold 4 that joins with it is set, the hot blast manifold opening part is established valve 7, shock mount 8 between valve and hot blast manifold wall, the hot blast manifold inner chamber is established heating 5, the hot blast manifold machine 6 of giving a dinner for a visitor from afar, electric cabinet 10 binding post a, b, c are connected at temperature measuring head 9, hot blast manifold heating 5 and the blower fan 6 of filter chamber discharge pipe 3 respectively.
After taking new technical measures, when operation starts, electrical control circuit at first starts blower fan and hot blast manifold electrical heating elements, open the hot blast manifold valve, hot blast enters the deduster filter chamber through the filter chamber blast pipe, make in the filter chamber hot blast even, can effectively realize anti-condensation, overcome the prior art heating uneven, easily burn defective such as heating element heater.
Description of drawings:
Accompanying drawing 1 sack cleaner filter chamber preheating device organigram
Accompanying drawing 1 sack cleaner filter chamber preheating device organigram, the embodiment of the invention is provided, wherein, sack cleaner filter chamber 2, blast pipe 1 and discharge pipe 3 are arranged, in sack cleaner filter chamber blast pipe 1 hot blast manifold 4 that joins with it is set, the hot blast manifold opening part is established valve 7, shock mount 8 between valve and hot blast manifold wall, the hot blast manifold inner chamber is established heating 5, the hot blast manifold machine 6 of giving a dinner for a visitor from afar, electric cabinet 10 binding post a, b, c are connected at temperature measuring head 9, hot blast manifold heating 5 and the blower fan 6 of filter chamber discharge pipe 3 respectively.
When operation starts, at first start preheating device, connect electrical heating elements 5 and blower fan 6, send hot blast to open valve by hot blast manifold by blower fan, send hot blast through the filter chamber blast pipe to the deduster filter chamber, with anti-condensation, treat that filter chamber heats up, when the temperature measuring head feedback signal is higher than setting value, preheating device quits work, valve is closed under the spring tension effect, begins into flue gas, and deduster enters normal dedusting duty.
