Description

The cessation reaction jar of band spray equipment

Technical field

The utility model relates to the cessation reaction jar, what be specifically related to is a kind of cessation reaction jar that has spray equipment and can prevent solid accumulation.

Background technology

In the daily production of acrylic fiber industry, mix monomer is reacting generating copolymer in polymeric kettle, and polymer will pass through a surge tank, enters to take off Dan Ta and take off list again, and this surge tank is for being called the cessation reaction jar.

Existing cessation reaction jar stirs for making the material in the cessation reaction jar as shown in Figure 1, needs built-in agitator.But in the process that reality stirs, above material liquid surface, can form a large amount of spittle.These spittle can attachment phenomenon occur in the cessation reaction jar on tank deck and tank skin, and adheres to thickening with the carrying out that produces of accumulation and increase gradually.In 50～60 days production run cycle, the tank skin of cessation reaction jar and tank deck are piled up the thickness of material even up to 200 millimeters.These materials contain a large amount of monomers, and skin is had the strong impulse effect.After reaching the cycle of operation, operating personnel need be with gas defence face to enter in the jar from manhole, because jar interior space is limited, cleaning work is very inconvenient, and difficulty is also very big; More seriously operating personnel not only are difficult to breathe in jar, also will bear a large amount of monomers in the material simultaneously to the tingling sensation of skin; Contain little Molecularly Imprinted Polymer and monomer in the material that cleans out in addition, can't reclaim, can only burn, return enterprise in the time of contaminated environment and caused the certain economic loss indirectly.If running into the material liquid level fluctuates, the material of those bulk depositions will come off, cause stifled pump, liquid level distortion, the uncontrollable situation of discharging, must stop when serious and handle, this can allow labor intensity of operating staff increase, and makes enterprise additionally increase maintenance cost again simultaneously, prolong the production run time and lowered production efficiency, directly cause enterprise to suffer bigger economic loss.

Summary of the invention

Goal of the invention of the present utility model is to provide a kind of cessation reaction jar with spray equipment at the problems referred to above, is used to solve former problem of adhering to accumulation with material in the cessation reaction jar.

The utility model is achieved through the following technical solutions: the cessation reaction jar of band spray equipment comprises tank body, agitator, material inlet pipe, blow-down pipe are arranged at the tank body top, agitator is installed in tank interior, it is characterized in that: spray equipment is equipped with at described tank body top; Wherein, spray equipment is made of shower water distributor, baffle plate, inlet attack, pressure angle adjustable pipe; Baffle plate is two, places shower water distributor two ends up and down respectively; Inlet attack is communicated with pressure angle adjustable pipe on being arranged on shower water distributor sidewall through the shower water distributor.

Described pressure angle adjustable pipe is evenly distributed on the sidewall of shower water distributor radially.

Adopt the good effect of technique scheme: the utility model is to install spray equipment additional at cessation reaction tank top; make external water under high pressure in jar, form the vaporific diaphragm of one deck through spray equipment; having blocked the material liquid surface top spittle contacts with the direct of tank deck or tank skin; stopped the phenomenon that material adheres to accumulation in a large number; reduced loss of material; avoided of the influence of temporary needs sewage effluent to environmental protection; reduced the labour intensity of operating personnel's cleanings; shortened the cleaning maintenance time; improve operating efficiency, increased economic benefit of enterprises.

Four, description of drawings

Fig. 1 is former structural representation with the cessation reaction jar;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the structural representation of spray equipment in the utility model.

Among the figure: 1 tank body, 2 manholes, 3 material inlet pipes, 4 blow-down pipes, 5 agitators, 6 shower water distributors, 7 baffle plates, 8 inlet attacks, 9 pressure angle adjustable pipes.

Five, the specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 2 is a structural representation of the present utility model, and as shown in the figure, the cessation reaction jar of band spray equipment comprises tank body 1, agitator 5.Blow-down pipe 4 in the tank filling is arranged at tank body 1 top, is used for emptying keeping jar inner and outer air pressure in certain scope, the effect of secure production safety.Tank body 1 is equipped with material inlet pipe 3, and material inlet pipe 3 one end openings can directly be delivered to material tank body 1 bottom in tank body 1 bottom.Agitator 5 is installed in tank body 1 inside, is convenient to the material in the direct agitator tank.

Fig. 3 is the structural representation of spray equipment in the utility model, and as shown in the figure, the cessation reaction jar of band spray equipment also comprises spray equipment, and spray equipment is installed in tank body 1 top.Spray equipment is made of shower water distributor 6, baffle plate 7, inlet attack 8, pressure angle adjustable pipe 9, and baffle plate 7 is two, and overhead gage is installed in shower water distributor 6 upper ends, and lower baffle plate is installed in shower water distributor 6 lower ends.One end of shower water distributor 6 is communicated with inlet attack 8, and the sidewall of shower water distributor 6 is provided with pressure angle adjustable pipe 9, and pressure angle adjustable pipe 9 is the adjustable pipes that have adjustable-angle and pressure function by the end that φ 6 * 1 pipelines are made.After the spray equipment integral installation, can make inlet attack 8 through shower water distributor 6 indirectly be arranged on shower water distributor 6 sidewalls on pressure angle adjustable pipe 9 be communicated with.In addition, consider the actual spray effect and the cost of erection unit, quantity that can pressure angle adjustable pipe 9 is set to six to ten, is optimal number with eight wherein, and is evenly distributed on radially on the sidewall of shower water distributor 6.

With Daqing petrochemical company Acrylic Fibers Plant polymerization plant is example; during use; operating personnel at first regulate pressure and the angle that sets pressure angle adjustable pipe 9 in the spray equipment; again with the 8 external water under high pressures of the inlet attack in the spray equipment; pressure angle adjustable pipe 9 ejections of water under high pressure in spray equipment; the water under high pressure of ejection has formed the vaporific diaphragm of one deck in inner tank wall and tank deck; making inner tank wall and tank deck all will obtain water under high pressure protects fully; so also reached and broken off the purpose that the spittle and tank deck or tank skin directly contact; promptly reached the effect that the material spittle is separated with inner tank wall and tank deck; make the spittle no longer adventitious deposit at inner tank wall and tank deck; reduced loss of material; after the cessation reaction jar reaches the cycle of operation; open manhole 2; on the surface of tank deck and tank skin all is smooth clean; the phenomenon that has not had former a large amount of solid accumulations; this also greatly reduces the labour intensity of operating personnel's cleaning simultaneously; only need check whether the pressure angle adjustable pipe normally gets final product; both shortened the cleaning maintenance time; reduced environmental pollution; improve operating efficiency again, won bigger economic benefit for enterprise indirectly.

To stop 24 in car every year is example, 0.2 ton of the material of suppose at every turn to reduce the loss, average 1.2 ten thousand yuan of material per ton, annual for enterprise's increase economic benefit be ten thousand yuan of 24.0 * 0.2 * 1.2=5.8.
