Description
Technical field
The present invention relates to Environmental-protecting dust-removing plant equipment manufacturing technology field, especially a kind of for having the whether intact filter bag of self filtering function of detection in cleaner.
Background technology
Bag-type dust equipment is a kind of equipment that dust and dust are separated from flue gas, and it is widely used in the dedusting of the industries such as iron and steel, thermal power generation, cement, mining.Along with country's improving constantly environmental requirement, environmental protection policy is day by day severe, and each manufacturer all pays much attention to environmental protection, adopts a large amount of bag-type dust equipment to process and pollutes waste gas, improvement post dust.The operation principle of bag-type dust equipment is: the flue gas containing dust and dust enters the visceral-qi room of deduster inner sealing card bottom from the air inlet of cleaner, and deduster inside is provided with the dedusting filtering bag of multiple 2 ~ 10 meters long, and filter bag majority adopts cloth bag; Filter bag material has natural fiber, chemical synthetic fiber, glass fibre or metallic fiber etc., has cage bone to support in filter bag.Dust remover roof has one deck sealing card to prevent smoke spillage, the top of filter bag is the filter pocket mouths through sealing card, filter pocket mouths is communicated with discharge duct by sealing card top air-purifying chamber, filter bag inside is entered through filter bag after flue gas enters deduster inside, as shown in Figure 7, dust and dust are blocked in filter bag outside, and the gas after filtration enters discharge duct by filter pocket mouths by sealing card top air-purifying chamber, reaches the effect of purifying smoke.
In daily bag-type dust equipment use process, running check, the filter bag safeguarded in bag-type dust equipment, i.e. cloth bag; But the Measures compare of existing inspection cloth bag broken hole, wearing and tearing is loaded down with trivial details.Conventional method is: 1, on cleaner card, check cloth bag one by one; 2, enter cleaner casing, whether have run-down one by one bottom inspection cloth bag; 3, adopt leak hunting instrument, check cloth bag leak situation.All there is the problem that labour intensity is large, Detection accuracy is low and proof cycle is long in these three kinds of methods, thus causes checking efficiency low, wastes a large amount of manpower and materials, delay operation hours.
Summary of the invention
The object of this invention is to provide a kind of dedusting filtering bag, it can solve inspection dedusting filtering bag that prior art exists when whether having run-down labour intensity large, Detection accuracy and the low problem of checking efficiency.
In order to solve the problem, the technical solution used in the present invention is: this dedusting filtering bag, includes the filter pocket mouths be located on filter bag body; Detection bag is provided with in described filter bag body.
In technique scheme, more specifically scheme can also be: described detection bag includes the bottom surface being provided with fixed part, and be located at the detection bag that the little bottom of oral area on described bottom surface is large, the detection sack of described detection bag is near described fixed part one end; Described detection bag is connected with described filter bag body by described fixed part; Described detection bag body is positioned at described bottom surface and described filter bag body is connected with between the inwall of described that side of fixed part.
Further: described bottom surface and described detection bag are terylene filter screen, and the aperture of described filter screen is less than 0. 1 millimeters; Liner is provided with between described fixed part and described filter bag body.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, detection bag is provided with in dedusting filtering bag, when checking that whether cloth bag is damaged, as long as observe in detection bag transparent in cloth bag the quality whether having dust just can judge dedusting filtering bag on cleaner card, very simply; Labour intensity is low, and Detection accuracy reaches 100%, and detection efficiency is high.
2, less investment.Compared with detecting cloth bag leak with machinery, instrument, fund input is low, can ignore.Other affiliated facilities need not be increased simultaneously.
3, simple installation.It is outside that this infant industry cloth bag is arranged on dedusting skeleton, and head is buckled on card, and integral installation is simple and reliable.
4, online or offline inspection can be realized.According to cleaner service requirement, can realize online or offline inspection cloth bag broken hole problem.Improve the operational efficiency of cleaner.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the invention will be further described:
The dedusting filtering bag of Fig. 1, Fig. 2, includes filter pocket mouths 1 and filter bag body 2; Detection bag 3 is provided with in filter bag body 2.
Shown in Fig. 3, Fig. 4 and Fig. 5, detection bag 3 includes the bottom surface 3-1 being provided with fixed part, is located at the detection bag 3-3 that the little bottom of oral area on the 3-1 of bottom surface is large, detects the detection sack 3-2 of bag 3-3 near fixed part one end of bottom surface 3-1; Detect bag 3-3 to be connected with filter bag body 2 by the fixed part of bottom surface 3-1; Detect bag 3-3 between bottom surface 3-1 and the inwall of filter bag body 2.
Bottom surface 3-1 and detection bag 3-3 is the transparent filter screen of terylene at the present embodiment, can be the filter screen of other materials such as gauze, nylon, PPS or glass in other embodiment; The aperture of filter screen is less than 0. 1 millimeters; Be provided with liner between the fixed part of bottom surface 3-1 and filter bag body 2, liner is made for adding transparent filter screen with terylene pin felt rug.
Operation principle of the present invention is as shown in Fig. 2, Fig. 6 and Fig. 7:
Fig. 2 is that before dedusting fan is opened, detection bag 3 gravitate nature vertically downward, does not have dust in detection bag 3 bags.
Fig. 6 is that after dedusting fan is opened, due to the effect of negative pressure and wind-force, detection bag 3 is stood upside down, and detect sack 3-2 and open downwards, in figure, arrow is depicted as gas flow direction; If during the phenomenons such as the filter bag body 2 of dedusting filtering bag is leaky, cut, in dusty gas, dust is through filter bag, and the fraction dust 4 leaked through is detected bag 3-3 by leak detection sack 3-2 and collects, and dust 4 constantly accumulates in detection bag 3.
Fig. 7 is after dedusting fan is shut down or Off-line valve closes, detection bag 3 due to Action of Gravity Field downward immediately, homing, detects sack 3-2 upwards, and dust 4 is installed in and detects in bag 3-3.
Staff is when checking the whether leaky or cut of filter bag, open cleaner upper box access door, as long as observe in filter bag from filter pocket mouths 1 on card, see that detection bag 3 is built with dust 4, can determine that this filter bag exists the phenomenons such as run-down hole or cut, illustrate that this filter bag damages, can not use, need to change; If there is no dust 4 in detection bag 3, illustrate that filter bag is intact.
